Effect of School Based Obesity Interventions

Effect of School Based Obesity Interventions ABSTRACT Introduction Background Obesity in both adult and children is fast becoming one of the most serious public health problems of the 21st century in developed and developing countries alike. It is estimated that approximately 10% of school age children. The prevalence of childhood overweight and obesity is ever on the increase in the UK as in the rest of the world. It is estimated that the prevalence of overweight and obesity among 2 10 year old children in the UK rose from 22.7%-27.7% and 9.9%-13.7% respectively between 1995 and 2003; these figures are set to increase unless something is done. School-based interventions offer a possible solution in halting obesity prevalence, because the school setting provides an avenue for reaching out to a high percentage of children (especially in the western world), opportunity for constant monitoring of children and the resources for anti-obesity interventions. Objectives To systematically review the evidence of the impact of school-based interventions to prevent childhood obesity on: Adiposity (primary objective) Knowledge, physical activity levels and diet (secondary objectives) Methods The review was done following the Cochrane collaboration guidelines. In addition to searching electronic databases, first authors of all included studies were contacted. A recognised critical appraisal tool was used to assess the quality of included studies. Results Three RCTs and one CCT met the inclusion criteria for the review. All four studies had a control and intervention group; with various study limitations. While none of the studies found statistically significant BMI changes in intervention groups when compared with control group post-intervention, all of them recorded either a significant change in diet, or an increase in physical activity levels. INTRODUCTION BACKGROUND Obesity is generally understood as abnormal accumulation of fat to the extent that presents health risk (Kiess, Marcus et al. 2004), and was added to the international classification of diseases for the first time in 1948 (Kipping, Jago et al. 2008). The worldwide clinical definition of adult obesity by the WHO is body mass index (BMI) ≠¥ 30kg/m2 (WHO 2006). In children however, because of the significant changes in their BMI with age (Cole, Bellizzi et al. 2000), there is no universally accepted definition of obesity (Parizkova and Hills 2004; Bessesen 2008) and it therefore varies from country-to-country. The most commonly used definition of childhood obesity is the US definition which measures overweight and obesity in a reference population using the cut off points of 85th and 95th centiles of BMI for age (Ogden, Yanovski et al. 2007). In the UK, overweight and obesity are diagnosed using a national reference data from a 1990 BMI survey of British children (Stamatakis, Prima testa et al. 2005). Children whose weights are above the 85th centile are classed as overweight and over the 95th centile are considered obese (Reilly, Wilson et al. 2002). Recent estimates suggest that obesity has reached epidemic proportions globally with about 400 million adults being clinically obese, a figure projected to rise to about 700 million by 2015 (WHO 2006). In children, the current WHO estimates are that about 22 million children globally under age 5 are overweight (WHO 2008). In the UK, evidence suggests that obesity is set to be the number one preventable cause of disease in a matter of time (Simon, Everitt et al. 2005). In the last three decades, the scale as well as the prevalence of obesity have grown rapidly amongst all age, social and ethnic groups in the UK, as well as globally (Table 1)(Kipping, Jago et al. 2008). Estimates suggest that in the UK, between 1984 and 2002/2003, the prevalence of obesity in boys aged 5-10 rose by 4.16%, and by 4.8% in girls (Stamatakis, Primatesta et al. 2005). There is therefore there is an urgent need for the development and implementation of effective intervention strategies to halt the ever increasing obesity prevalence (Summerbell Carolyn, Waters et al. 2005). OBESITY CAUSATION The primary risk factors associated with the increase in prevalence of childhood obesity are ever increasing involvement in sedentary lifestyles and an increase also in the consumption of high energy dense food and drink (Ebbeling, Pawlak et al. 2002; Sekine, Yamagami et al. 2002; Speiser, Rudolf et al. 2005; Topp, Jacks et al. 2009). The underlying mechanism of obesity formation is an imbalance between energy input and expenditure (Moran 1999; Kipping, Jago et al. 2008) Genetic and environmental factors greatly influence the bodys energy balance. Nevertheless, genetic conditions which either cause production of excessive fat in the body or reduce the rate at which it is broken down, of which Prader-Willi syndrome is an example account for less than 5% of obese individuals (Speiser, Rudolf et al. 2005), with environmental factors accounting for a very high percentage (French, Story et al. 2001). The major cause of the rising obesity problem is arguably changes in physical and social environments (French, Story et al. 2001). In recent times, there has been a remarkable shift towards activities that do not promote energy expenditure, for example, most children would travel to school in cars rather walk, in contrast to what obtained in the 1970s (Popkin, Duffey et al. 2005; Anderson and Butcher 2006). There is evidence to suggest that obese children are less active than their non-obese counterparts, hence promoting physical activity such as walking or exercising will help prevent obesity in children (Hughes, Henderson et al. 2006). Media time (television viewing, playing video games and using the computer) has been identified as one of the significant environmental changes responsible for the surge in childhood obesity. Besides promoting physical inactivity, it encourages energy input via excessive snacking and inappropriate food choices as a result of television advertisements (Ebbeling, Pawlak et al. 2002; Speiser, Rudolf et al. 2005). Robinson in his study reveals that â€Å"between ages 2 and 17, children spend an average of 3 years of their waking lifetime watching television alone† (Robinson 1998). Parents play a significant role in where, what and how much their children eat and to an extent, how physically active their children are. In most homes, children make their food choices based on the options they are presented with by their parents, and they characteristically would go for wrong option, more so if they have an obese parent (Strauss and Knight 1999). Other changes within the family such as physical inactivity and working patterns of parents have contributed somewhat to the obesity epidemic. In a family where the parents work full-time, there tends to be very little time for them to prepare wholesome home-made meals and this could possibly explain the increasing demand for eating out (Anderson and Butcher 2006) thereby increasing intake of high energy dense food. Childrens attitude to and participation in physical activities depends largely on how physically active their parents are. Thus children of sporty parents embrace exercise heartily and are therefore less prone to becoming obese.(Sallis, Prochaska et al. 2000). In addition to these family factors, societal factors such as high crime rate, access to safe sports/recreational facilities, transportation and fewer physical education programs in schools significantly impact on energy balance (Koplan, Liverman et al. 2005; Popkin, Duffey et al. 2005; Topp, Jacks et al. 2009). French summarizes the environmental influence on obesity by opining that â€Å"The current epidemic of obesity is caused largely by an environment that promotes excessive food intake and discourages physical activity† (French, Story et al. 2001) CONSEQUENCES OF OBESITY Evidence suggests that childhood obesity and/or overweight has a great impact on both physical and psychological health; causing effects such as behavioral problems and low self esteem, with a higher risk in girls than in boys (Reilly, Methven et al. 2003). Although most of the serious consequences do not become evident until adulthood, research has shown childhood obesity to be linked to metabolic disorders such as insulin resistance and type 2 diabetes, stroke and heart attacks, sleep apnea, nonalchoholic fatty liver disease, higher incidence of cancers, depression, dyslipidaemia, increased blood clotting tendency, etc (Ebbeling, Pawlak et al. 2002; Reilly, Methven et al. 2003; Kiess, Marcus et al. 2004; D. A. Lawlor, C. J. Riddoch et al. 2005; Daniels 2006; WHO 2006). One of the long-term serious consequences of childhood obesity is that obese children are twice more likely to grow into obese adults than their non-obese counterparts (Moran 1999); however, this largely depends on factors such as age of onset, severity of the disease and the presence of the disease in one parent (Moran 1999; Campbell, Waters et al. 2001; Kiess, Marcus et al. 2004; WHO 2006). Other long term consequences include early death and adverse socio-economic consequences such as poor educational attainment and low/no income in adulthood (Reilly, Methven et al. 2003; Fowler-Brown and Kahwati 2004; Kiess, Marcus et al. 2004). Obesity-related morbidity places a huge and growing financial demand on governments. In the UK alone, the Department of Health has reported that obesity costs the NHS and the UK economy as a whole about  £1b and between  £2.3b  £2.6b annually respectively, with the cost to the NHS projected to rise to  £3.6b by 2010 (DH 2007). TREATMENT AND PREVENTION The treatment of obesity requires a multidisciplinary approach due to the multi-faceted nature of the condition (Parizkova and Hills 2004). This is aimed at reducing caloric intake and increasing energy expenditure through physical activity (Ebbeling, Pawlak et al. 2002). These interventions are more likely to be successful if the patients family is involved and the treatment tailored to individual needs and circumstances (Fowler-Brown and Kahwati 2004). In extreme cases, options such as surgical and pharmacological treatments could be exploited. These options are very unpopular and usually not recommended because the associated health risks outweigh the benefits by far (Epstein, Myers et al. 1998; Ebbeling, Pawlak et al. 2002). Considering the huge costs and high levels of treatment failure associated with obesity treatment (Stewart, Chapple et al. 2008), the axiom by Benjamin Franklin cannot describe any other condition better than it describes obesity management. â€Å"An ounce of prevention is worth a pound of cure† Dietz et al confirm this by saying that prevention remains the best and most effective management of obesity (Dietz and Gortmaker 2001). Obesity prevention interventions are usually set either in the home or at school with an objective of eliminating peer pressure and, by so doing effect behavioral change (Ebbeling, Pawlak et al. 2002). Literature suggests that the school has so far remained the choice setting for these preventive interventions despite the very limited evidence on its effectiveness (Birch and Ventura 2009). Why is the school setting a good focus of intervention? Approximately 90% of children are enrolled in schools in developed countries (Baranowsk, Cullen et al. 2002) Children spend a substantial amount of time in school and therefore consume a considerable proportion of their daily calories at school (Katz, OConnell et al. 2005) School related activities present an opportunity to educate children on the concept of energy balance, healthy living and how to make appropriate food choices (Ebbeling, Pawlak et al. 2002; Koplan, Liverman et al. 2005) It offers opportunity for continuity and constant monitoring via frequent contact (Baranowski T 2002) Schools have an availability of existing manpower and facilities needed for anti-obesity interventions (Kropski, Keckley et al. 2008) In a nut shell, â€Å"Schools offer many other opportunities for learning and practicing healthful eating and physical activity behaviors. Coordinated changes in the curriculum, the in-school advertising environment, school health services, and after-school programs all offer the potential to advance obesity prevention† (Koplan, Liverman et al. 2005). PREVIOUS SYSTEMATIC REVIEWS Systematic reviews have been conducted on the effectiveness of school-based interventions in the prevention of childhood obesity. Campbell et al (2001), conducted a systematic review of 7 randomised control trials (RCTs) (6 were school-based, varying in length of time, target population, quality of study and intervention approach). The review found that dietary and physical education interventions have an effect on childhood obesity prevalence. However, success varied with different interventions amongst different age groups. Two of the three long term studies that focused on a combination of dietary education and physical activity, and dietary education respectively reported an effect on obesity prevalence reduction. Similarly, 1 out of the 3 school based short-term interventions that focused only on reducing sedentary activity also found an effect on obesity prevalence. While this review shows that dietary and physical activity interventions based at school are effective against th e risk factors of obesity, the question of generalisability and reproducibility arises as the review reports the majority of the included primary studies were carried out in the US. Most of the studies used BMI as a measure of adiposity, and BMI as has been documented varies across ethnic and racial groups (Rush, Goedecke et al. 2007), thus, it will be inappropriate to apply the findings of US-based obesity prevention interventions to children in middle and low income countries where conditions are different. There are also concerns about the methodology and study design. For example the school-based study by Gotmaker et al (1999) had limitations such as low participation rate (65%) and the researchers were unable to adjust for maturity in boys and there was also poor assessment of dietary intake. All these limitations could have been responsible for a high percentage of the reported intervention effect thus affecting the validity of the results of the study (Gortmaker, Peterson et al. 1999). The authors of the review however concluded that there is currently very limited high quality evidence on which to draw conclusions on the effectiveness of anti-obesity programmes. A Cochrane review which is an update of the Campbell et al (2001) study by Summerbell et al (2005) has examined the impact of diet, physical activity and/or lifestyle and social support on childhood obesity prevention. Their review examined the effectiveness of childhood obesity prevention interventions which included school based interventions. Their study included 10 long-term (a minimum duration of 12 months) and 12 short-term (12weeks 12 months) clinical trials (randomised and controlled). 19 out of the 22 studies that met their inclusion criteria were school/pre-school based. The study chose the appropriate study type; more than one reviewer was involved in the entire process of data collection, extraction and selection of included studies. In general, the study found that most of the school-based interventions (dietary and/or physical activity) reported some positive changes in targeted behaviours, but however had very little or no statistically significant impact on BMI. The reviewers stated that none of the 22 studies fulfilled the quality criteria because of some form of methodological weakness which includes measurement errors. For instance, the study by Jenner et al (1989) had no valid method of measuring food intake. The studies by Crawford et al (1994), Lannotti et al (1994) and Sallis et al (2000) had similar measurement errors. Reporting error was identified in studies by Little et al (1999) and Macdiarmid et al (1998). There were also reliability concerns about the secondary outcomes measurement in some of the included studies. The reviewers therefore expressed the need for further high quality research on effectiveness. Kropski et al (2008) reviewed 14 school-based studies that were designed to effect a life style change, a change in BMI, decrease overweight prevalence through a change in nutrition, physical activity or a combination of both. Of the 14 studies, three were done in the UK, one in Germany and 10 in the US. The right type of studies were chosen for this review and the whole process was done by more than one reviewer, however they were unable to draw strong conclusions on the efficacy of school-based interventions because of the limited number of primary studies available and methodological or design concerns which include: small sample size (Luepker, Perry et al. 1996; Mo-suwan, Pongprapai et al. 1998; Nader, Stone et al. 1999; Warren, Henry et al. 2003), no intention-to treat analysis (Danielzik, Pust et al.; Sallis, McKenzie et al. 1993; Sahota, Rudolf et al. 2001; Warren, Henry et al. 2003), possibility of type I (Coleman, Tiller et al. 2005) and type II errors (Warren, Henry et al. 2003), unit of analysis errors (Sallis, McKenzie et al. 1993) and inconsistent results (Mo-suwan, Pongprapai et al. 1998; Caballero, Clay et al. 2003; Coleman, Tiller et al. 2005). Despite their inability to draw a conclusion on effectiveness, overall, the review found that a combination of nutritional and physical activity interventions had the most effect on BMI and prevalence of overweight, with the result largely varying from community-to-community. The nutrition only and physical activity only interventions appeared to have had a change on lifestyles of participants but either had no significant effect on the measures of overweight or no BMI outcomes were measured. Another systematic review on the effectiveness of school-based interventions among Chinese school children was carried out by M.Li et al (2008). The authors included 22 primary studies in their review. The review reported that the primary studies showed that there are some beneficial effects of school-based interventions for obesity prevention; the reviewers however expressed their concerns that most of the studies included in the review had what they considered to be serious to moderate methodological weaknesses. Sixteen of the 22 studies included studies were cluster control trials, and there was no mention by any of the researchers that cluster analysis was applied to any of the 16 studies. In addition to lack of cluster analysis, no process evaluation was conducted in any of the studies. Only one study performed an intention to treat analysis. Twelve studies experienced dropouts, but there was incomplete information on the study population at the end of the trial and the reason f or the dropouts. Additionally, none of the studies explained the theory upon which they based their intervention. There was also potential recruitment and selection bias in all the primary studies as identified by the reviewers. They stated that none of the studies reported the number of subjects that were approached for recruitment into the study. As none of the RCTs included described the method they used in randomization, neither did they state if the studies were blinded or not. The methodological flaws in a high percentage of the included primary studies could impact on the validity of the findings of the review. Again, the authors failed to reach a conclusion on the effectiveness of the interventions because of the intrinsic weaknesses found in the primary studies, and as a result state the need for more primary studies that would address the methodological weaknesses that is highly present in nearly all existing primary studies conducted on this topic so far. The study of the efficacy of school-based interventions aimed at preventing childhood obesity or reducing the risk factors is a rather complex one. Pertinent issues on effectiveness of school-based interventions to prevent the risk factors of obesity remain that there is very limited/weak evidence on which to base policies on. Heterogeneity of primary research (in terms if age of study population, duration of intervention, measurement of outcomes and outcomes measured) makes further statistical analysis nearly impossible. BMI is currently the most widely used measure of overweight and obesity in children. However, BMI has no way of distinguishing between fat mass and muscle mass in the body and might therefore misdiagnose children with bigger muscles as obese. Another disadvantage of using BMI in overweight measurement is its inability of depicting the body fat composition (Committee on Nutrition 2003), other surrogate indicators of adiposity may be needed. Most authors that have carried out a review on this topic so far have expressed the need for further research on this topic to add to the existing body of evidence. RATIONALE FOR THIS STUDY All the systematic reviews on this subject so far have focused mainly on the United States. Lifestyle differences such as eating habits between American and British children possibly affect generalisability and reproducibility of US findings to the UK. For example, in the US, research has shown that 0.5% of all television advertisements promote food, and that about 72% of these food advertisements promote unhealthy food such as candy and fast food (Darwin 2009). In the UK paradoxically, the government in 2007 enforced regulations banning television advertisement of unhealthy foods (foods with high fat, salt, and sugar content) during television programmes aimed at children below 16 years of age (Darwin 2009). Thus US children are at a higher risk of becoming obese than their UK counterparts as a result of higher rate of exposure to TV junk food advertisements. Another lifestyle difference between American and British children is physical activity. In the UK, a high percentage of children aged 2 to 15 achieve at least 60 minutes of physical activity daily (about 70% of males and 60% of females) (DoH 2004), as opposed to the US where only about 34% of school pupils achieve the daily recommended levels of physical activity daily (CDC 2008). These differences highlight the importance of public health policies being based on the local population characteristics rather than on imported overseas figures. There is therefore need to review the evidence of UK school-based obesity interventions to inform policy relevant to the UK population. To the best of my knowledge following an extensive literature search, no systematic review has been conducted on the effectiveness of school-based intervention in preventing childhood obesity in the UK, despite the high prevalence of the condition and its public health significance in this country. This research aims to bridge this gap in knowledge by focusing on UK based studies to evaluate the efficacy of school-based interventions in the UK population. This study therefore stands out insofar as it will be assessing the effectiveness of school-based interventions in the reducing the risk factors of obesity in the UK, with a hope of providing specific local recommendations based on UK evidence. This type of review is long overdue in the UK, considering that the governments target to reduce childhood obesity to its pre-2000 levels by the year 2020 (DoH 2007) will require local evidence of effective interventions to succeed. The next stage of this review will describe in detail the research methodology to be used to conduct the proposed systematic review. Also included will be research strategy details to be adopted, study selection criteria, data collection and analysis. AIMS AND OBJECTIVES The aim of this research is to: Systematically review school-based intervention studies in the UK aimed at reducing the risk factors of childhood obesity among school children. Objectives are: To assess the efficacy of school-based anti-obesity interventions in the UK. To identify the most effective form of school-based interventions in the prevention of childhood obesity amongst school children in the UK. CRITERIA FOR INCLUDING STUDIES IN THIS REVIEW METHODS This review was performed as a Cochrane review. The Cochrane guidance on systematic reviews and reporting format were as far as possible adhered to by the author (Green, Higgins et al. 2008). The entire review process was guided by a tool for assessing the quality of systematic reviews, alongside the accompanying guidance (health-evidence.ca 2007a; health-evidence.ca 2007b). TYPES OF STUDY In the search for the effectiveness of an intervention, well conducted randomised control trials (which are the best and most credible sources of evidence) will be the preferred source of studies for this review. However, because of the limited number of RCTs conducted on this topic so far, this study will include controlled clinical trials if there is insufficient availability of RCTs. TYPES OF PARTICIPANTS School children under 18 years of age TYPES OF INTERVENTIONS Interventions being evaluated are those that aim to: Reduce sedentary lifestyle Effect nutritional change Combine the two outcomes above Reduce obesity prevalence Effect an attitude change towards physical activity and diet Studies that present a baseline and post intervention measure of primary outcome. Interventions not included in this study are: Those with no specified weight-related outcomes Those that involved school-age children but were delivered outside of the school setting, as our focus is based on school-based interventions aimed at obesity prevention. Studies done outside the UK Studies with no specified interventions Non-RCTs or CCTs For each intervention, the control group will be school children not receiving the intervention(s). TYPES OF OUTCOMES MEASURED Primary outcomes Change in adiposity measured as BMI and/or skin fold thickness Secondary outcomes Knowledge Physical activity levels Diet SEARCH METHODS FOR IDENTIFICATION OF STUDIES Electronic searches The electronic databases OVID MEDLINE ® (1950-2009), PsycINFO (1982-2009), EMBASE (1980-2009) and the British Nursing Index (1994-2009) were all searched using the OVID SP interface. The Wiley Interscience interface was used to search the following databases: Cochrane Central Register of Controlled Trials and Database of Abstracts of Reviews of Effects. There was also a general search of internet using Google search engine, in an attempt to identify any ongoing studies or unpublished reports before proceeding to search grey literature sources. Grey literature For references to childhood obesity prevention in schools, the following grey literature sources were searched: British Library Integrated Catalogue (http://catalogue.bl.uk/F/?func=filefile_name=login-bl-list) ISI index of Conference Proceedings (http://wok.mimas.ac.uk/) SCIRUS (http://www.scirus.com/) System for Information on Grey Literature (http://opensigle.inist.fr/) ZETOC (http://zetoc.mimas.ac.uk) Additionally, current control trials database at http://www.controlled-trials.com/ was searched for any ongoing research. The UK national research register was also searched at https://portal.nihr.ac.uk/Pages/NRRArchive.aspx. All the links to the grey literature databases were tested at the time of this review and found to be working. Hand searches It was not possible to conduct a hand search of journals due to pragmatic reasons. Reference lists Reference lists of retrieved studies were searched for other potential relevant studies that might have been omitted in the earlier search. Correspondence First author of all included studies were contacted with a view to seeking more references. DATA COLLECTION AND ANALYSIS Selection of studies The abstracts and titles of the hits from the electronic databases searched were screened for relevance by a single assessor. Those that were thought to be potentially relevant were retrieved and downloaded unto EndnoteTM to make the results manageable and also avoid loss of data. At the end of the search, all databases were merged into one single database and duplicated records of the same study were removed. Subsequently, the assessor then sought and obtained the full text of, and reviewed the relevant studies that were considered eligible for inclusion. Multiple reports of same study were linked together. No further data were sought for studies not included in the review. Data extraction Data extraction from included studies was done by a single reviewer and the data recorded on a data extraction form. A summary of each included study was described according to these characteristics: Participants (age, ethnicity etc.), study design, description of school-based interventions, study quality and details such as follow-ups and date, location, outcomes measured, theoretical framework, baseline comparability and results Assessment of methodological quality of included studies A number of researchers (Jackson, Waters et al. 2005) and the Cochrane guidelines for systematic reviews of health promotion and public health interventions (Rebecca Armstrong, Waters et al. 2007) strongly advise using the Quality Assessment Tool for Quantitative Studies (2008a) developed by the Effective Public Health Practice Project in Canada and the accompanying dictionary (to act as a guideline) (2008b) in assessing methodological quality. Based on criteria such as selection bias, study design, blinding, cofounders, data collection methods, withdrawals and drop-outs and intervention integrity, the tool which is designed to cover any quantitative study employs the use of a scale (strong, moderate or weak) to assess the quality of each study included in the review. Analysis Considering the small number of studies included in the review and heterogeneity in terms of interventions, delivery methods, intensity of interventions, age of participants, duration of intervention and outcomes measured, it was not statistically appropriate to undertake a Meta analysis, which admittedly would have been the preferred method of analysing and summarising the results of the studies. A narrative synthesis of the results was done instead. RESULT DESCRIPTION OF STUDIES Results of the search The search of electronic sources identified 811 citations out of which 97 potential studies were retrieved. A reference management software EndnoteTM was used to search for and remove duplicate citations. Further screening of title and abstract reduced the number of citations to 17 potential studies. Full texts of the 17 studies were sought, 13 were excluded, and four met the inclusion criteria and were therefore included in the review. Authors of the four studies were then conta Effect of School Based Obesity Interventions Effect of School Based Obesity Interventions ABSTRACT Introduction Background Obesity in both adult and children is fast becoming one of the most serious public health problems of the 21st century in developed and developing countries alike. It is estimated that approximately 10% of school age children. The prevalence of childhood overweight and obesity is ever on the increase in the UK as in the rest of the world. It is estimated that the prevalence of overweight and obesity among 2 10 year old children in the UK rose from 22.7%-27.7% and 9.9%-13.7% respectively between 1995 and 2003; these figures are set to increase unless something is done. School-based interventions offer a possible solution in halting obesity prevalence, because the school setting provides an avenue for reaching out to a high percentage of children (especially in the western world), opportunity for constant monitoring of children and the resources for anti-obesity interventions. Objectives To systematically review the evidence of the impact of school-based interventions to prevent childhood obesity on: Adiposity (primary objective) Knowledge, physical activity levels and diet (secondary objectives) Methods The review was done following the Cochrane collaboration guidelines. In addition to searching electronic databases, first authors of all included studies were contacted. A recognised critical appraisal tool was used to assess the quality of included studies. Results Three RCTs and one CCT met the inclusion criteria for the review. All four studies had a control and intervention group; with various study limitations. While none of the studies found statistically significant BMI changes in intervention groups when compared with control group post-intervention, all of them recorded either a significant change in diet, or an increase in physical activity levels. INTRODUCTION BACKGROUND Obesity is generally understood as abnormal accumulation of fat to the extent that presents health risk (Kiess, Marcus et al. 2004), and was added to the international classification of diseases for the first time in 1948 (Kipping, Jago et al. 2008). The worldwide clinical definition of adult obesity by the WHO is body mass index (BMI) ≠¥ 30kg/m2 (WHO 2006). In children however, because of the significant changes in their BMI with age (Cole, Bellizzi et al. 2000), there is no universally accepted definition of obesity (Parizkova and Hills 2004; Bessesen 2008) and it therefore varies from country-to-country. The most commonly used definition of childhood obesity is the US definition which measures overweight and obesity in a reference population using the cut off points of 85th and 95th centiles of BMI for age (Ogden, Yanovski et al. 2007). In the UK, overweight and obesity are diagnosed using a national reference data from a 1990 BMI survey of British children (Stamatakis, Prima testa et al. 2005). Children whose weights are above the 85th centile are classed as overweight and over the 95th centile are considered obese (Reilly, Wilson et al. 2002). Recent estimates suggest that obesity has reached epidemic proportions globally with about 400 million adults being clinically obese, a figure projected to rise to about 700 million by 2015 (WHO 2006). In children, the current WHO estimates are that about 22 million children globally under age 5 are overweight (WHO 2008). In the UK, evidence suggests that obesity is set to be the number one preventable cause of disease in a matter of time (Simon, Everitt et al. 2005). In the last three decades, the scale as well as the prevalence of obesity have grown rapidly amongst all age, social and ethnic groups in the UK, as well as globally (Table 1)(Kipping, Jago et al. 2008). Estimates suggest that in the UK, between 1984 and 2002/2003, the prevalence of obesity in boys aged 5-10 rose by 4.16%, and by 4.8% in girls (Stamatakis, Primatesta et al. 2005). There is therefore there is an urgent need for the development and implementation of effective intervention strategies to halt the ever increasing obesity prevalence (Summerbell Carolyn, Waters et al. 2005). OBESITY CAUSATION The primary risk factors associated with the increase in prevalence of childhood obesity are ever increasing involvement in sedentary lifestyles and an increase also in the consumption of high energy dense food and drink (Ebbeling, Pawlak et al. 2002; Sekine, Yamagami et al. 2002; Speiser, Rudolf et al. 2005; Topp, Jacks et al. 2009). The underlying mechanism of obesity formation is an imbalance between energy input and expenditure (Moran 1999; Kipping, Jago et al. 2008) Genetic and environmental factors greatly influence the bodys energy balance. Nevertheless, genetic conditions which either cause production of excessive fat in the body or reduce the rate at which it is broken down, of which Prader-Willi syndrome is an example account for less than 5% of obese individuals (Speiser, Rudolf et al. 2005), with environmental factors accounting for a very high percentage (French, Story et al. 2001). The major cause of the rising obesity problem is arguably changes in physical and social environments (French, Story et al. 2001). In recent times, there has been a remarkable shift towards activities that do not promote energy expenditure, for example, most children would travel to school in cars rather walk, in contrast to what obtained in the 1970s (Popkin, Duffey et al. 2005; Anderson and Butcher 2006). There is evidence to suggest that obese children are less active than their non-obese counterparts, hence promoting physical activity such as walking or exercising will help prevent obesity in children (Hughes, Henderson et al. 2006). Media time (television viewing, playing video games and using the computer) has been identified as one of the significant environmental changes responsible for the surge in childhood obesity. Besides promoting physical inactivity, it encourages energy input via excessive snacking and inappropriate food choices as a result of television advertisements (Ebbeling, Pawlak et al. 2002; Speiser, Rudolf et al. 2005). Robinson in his study reveals that â€Å"between ages 2 and 17, children spend an average of 3 years of their waking lifetime watching television alone† (Robinson 1998). Parents play a significant role in where, what and how much their children eat and to an extent, how physically active their children are. In most homes, children make their food choices based on the options they are presented with by their parents, and they characteristically would go for wrong option, more so if they have an obese parent (Strauss and Knight 1999). Other changes within the family such as physical inactivity and working patterns of parents have contributed somewhat to the obesity epidemic. In a family where the parents work full-time, there tends to be very little time for them to prepare wholesome home-made meals and this could possibly explain the increasing demand for eating out (Anderson and Butcher 2006) thereby increasing intake of high energy dense food. Childrens attitude to and participation in physical activities depends largely on how physically active their parents are. Thus children of sporty parents embrace exercise heartily and are therefore less prone to becoming obese.(Sallis, Prochaska et al. 2000). In addition to these family factors, societal factors such as high crime rate, access to safe sports/recreational facilities, transportation and fewer physical education programs in schools significantly impact on energy balance (Koplan, Liverman et al. 2005; Popkin, Duffey et al. 2005; Topp, Jacks et al. 2009). French summarizes the environmental influence on obesity by opining that â€Å"The current epidemic of obesity is caused largely by an environment that promotes excessive food intake and discourages physical activity† (French, Story et al. 2001) CONSEQUENCES OF OBESITY Evidence suggests that childhood obesity and/or overweight has a great impact on both physical and psychological health; causing effects such as behavioral problems and low self esteem, with a higher risk in girls than in boys (Reilly, Methven et al. 2003). Although most of the serious consequences do not become evident until adulthood, research has shown childhood obesity to be linked to metabolic disorders such as insulin resistance and type 2 diabetes, stroke and heart attacks, sleep apnea, nonalchoholic fatty liver disease, higher incidence of cancers, depression, dyslipidaemia, increased blood clotting tendency, etc (Ebbeling, Pawlak et al. 2002; Reilly, Methven et al. 2003; Kiess, Marcus et al. 2004; D. A. Lawlor, C. J. Riddoch et al. 2005; Daniels 2006; WHO 2006). One of the long-term serious consequences of childhood obesity is that obese children are twice more likely to grow into obese adults than their non-obese counterparts (Moran 1999); however, this largely depends on factors such as age of onset, severity of the disease and the presence of the disease in one parent (Moran 1999; Campbell, Waters et al. 2001; Kiess, Marcus et al. 2004; WHO 2006). Other long term consequences include early death and adverse socio-economic consequences such as poor educational attainment and low/no income in adulthood (Reilly, Methven et al. 2003; Fowler-Brown and Kahwati 2004; Kiess, Marcus et al. 2004). Obesity-related morbidity places a huge and growing financial demand on governments. In the UK alone, the Department of Health has reported that obesity costs the NHS and the UK economy as a whole about  £1b and between  £2.3b  £2.6b annually respectively, with the cost to the NHS projected to rise to  £3.6b by 2010 (DH 2007). TREATMENT AND PREVENTION The treatment of obesity requires a multidisciplinary approach due to the multi-faceted nature of the condition (Parizkova and Hills 2004). This is aimed at reducing caloric intake and increasing energy expenditure through physical activity (Ebbeling, Pawlak et al. 2002). These interventions are more likely to be successful if the patients family is involved and the treatment tailored to individual needs and circumstances (Fowler-Brown and Kahwati 2004). In extreme cases, options such as surgical and pharmacological treatments could be exploited. These options are very unpopular and usually not recommended because the associated health risks outweigh the benefits by far (Epstein, Myers et al. 1998; Ebbeling, Pawlak et al. 2002). Considering the huge costs and high levels of treatment failure associated with obesity treatment (Stewart, Chapple et al. 2008), the axiom by Benjamin Franklin cannot describe any other condition better than it describes obesity management. â€Å"An ounce of prevention is worth a pound of cure† Dietz et al confirm this by saying that prevention remains the best and most effective management of obesity (Dietz and Gortmaker 2001). Obesity prevention interventions are usually set either in the home or at school with an objective of eliminating peer pressure and, by so doing effect behavioral change (Ebbeling, Pawlak et al. 2002). Literature suggests that the school has so far remained the choice setting for these preventive interventions despite the very limited evidence on its effectiveness (Birch and Ventura 2009). Why is the school setting a good focus of intervention? Approximately 90% of children are enrolled in schools in developed countries (Baranowsk, Cullen et al. 2002) Children spend a substantial amount of time in school and therefore consume a considerable proportion of their daily calories at school (Katz, OConnell et al. 2005) School related activities present an opportunity to educate children on the concept of energy balance, healthy living and how to make appropriate food choices (Ebbeling, Pawlak et al. 2002; Koplan, Liverman et al. 2005) It offers opportunity for continuity and constant monitoring via frequent contact (Baranowski T 2002) Schools have an availability of existing manpower and facilities needed for anti-obesity interventions (Kropski, Keckley et al. 2008) In a nut shell, â€Å"Schools offer many other opportunities for learning and practicing healthful eating and physical activity behaviors. Coordinated changes in the curriculum, the in-school advertising environment, school health services, and after-school programs all offer the potential to advance obesity prevention† (Koplan, Liverman et al. 2005). PREVIOUS SYSTEMATIC REVIEWS Systematic reviews have been conducted on the effectiveness of school-based interventions in the prevention of childhood obesity. Campbell et al (2001), conducted a systematic review of 7 randomised control trials (RCTs) (6 were school-based, varying in length of time, target population, quality of study and intervention approach). The review found that dietary and physical education interventions have an effect on childhood obesity prevalence. However, success varied with different interventions amongst different age groups. Two of the three long term studies that focused on a combination of dietary education and physical activity, and dietary education respectively reported an effect on obesity prevalence reduction. Similarly, 1 out of the 3 school based short-term interventions that focused only on reducing sedentary activity also found an effect on obesity prevalence. While this review shows that dietary and physical activity interventions based at school are effective against th e risk factors of obesity, the question of generalisability and reproducibility arises as the review reports the majority of the included primary studies were carried out in the US. Most of the studies used BMI as a measure of adiposity, and BMI as has been documented varies across ethnic and racial groups (Rush, Goedecke et al. 2007), thus, it will be inappropriate to apply the findings of US-based obesity prevention interventions to children in middle and low income countries where conditions are different. There are also concerns about the methodology and study design. For example the school-based study by Gotmaker et al (1999) had limitations such as low participation rate (65%) and the researchers were unable to adjust for maturity in boys and there was also poor assessment of dietary intake. All these limitations could have been responsible for a high percentage of the reported intervention effect thus affecting the validity of the results of the study (Gortmaker, Peterson et al. 1999). The authors of the review however concluded that there is currently very limited high quality evidence on which to draw conclusions on the effectiveness of anti-obesity programmes. A Cochrane review which is an update of the Campbell et al (2001) study by Summerbell et al (2005) has examined the impact of diet, physical activity and/or lifestyle and social support on childhood obesity prevention. Their review examined the effectiveness of childhood obesity prevention interventions which included school based interventions. Their study included 10 long-term (a minimum duration of 12 months) and 12 short-term (12weeks 12 months) clinical trials (randomised and controlled). 19 out of the 22 studies that met their inclusion criteria were school/pre-school based. The study chose the appropriate study type; more than one reviewer was involved in the entire process of data collection, extraction and selection of included studies. In general, the study found that most of the school-based interventions (dietary and/or physical activity) reported some positive changes in targeted behaviours, but however had very little or no statistically significant impact on BMI. The reviewers stated that none of the 22 studies fulfilled the quality criteria because of some form of methodological weakness which includes measurement errors. For instance, the study by Jenner et al (1989) had no valid method of measuring food intake. The studies by Crawford et al (1994), Lannotti et al (1994) and Sallis et al (2000) had similar measurement errors. Reporting error was identified in studies by Little et al (1999) and Macdiarmid et al (1998). There were also reliability concerns about the secondary outcomes measurement in some of the included studies. The reviewers therefore expressed the need for further high quality research on effectiveness. Kropski et al (2008) reviewed 14 school-based studies that were designed to effect a life style change, a change in BMI, decrease overweight prevalence through a change in nutrition, physical activity or a combination of both. Of the 14 studies, three were done in the UK, one in Germany and 10 in the US. The right type of studies were chosen for this review and the whole process was done by more than one reviewer, however they were unable to draw strong conclusions on the efficacy of school-based interventions because of the limited number of primary studies available and methodological or design concerns which include: small sample size (Luepker, Perry et al. 1996; Mo-suwan, Pongprapai et al. 1998; Nader, Stone et al. 1999; Warren, Henry et al. 2003), no intention-to treat analysis (Danielzik, Pust et al.; Sallis, McKenzie et al. 1993; Sahota, Rudolf et al. 2001; Warren, Henry et al. 2003), possibility of type I (Coleman, Tiller et al. 2005) and type II errors (Warren, Henry et al. 2003), unit of analysis errors (Sallis, McKenzie et al. 1993) and inconsistent results (Mo-suwan, Pongprapai et al. 1998; Caballero, Clay et al. 2003; Coleman, Tiller et al. 2005). Despite their inability to draw a conclusion on effectiveness, overall, the review found that a combination of nutritional and physical activity interventions had the most effect on BMI and prevalence of overweight, with the result largely varying from community-to-community. The nutrition only and physical activity only interventions appeared to have had a change on lifestyles of participants but either had no significant effect on the measures of overweight or no BMI outcomes were measured. Another systematic review on the effectiveness of school-based interventions among Chinese school children was carried out by M.Li et al (2008). The authors included 22 primary studies in their review. The review reported that the primary studies showed that there are some beneficial effects of school-based interventions for obesity prevention; the reviewers however expressed their concerns that most of the studies included in the review had what they considered to be serious to moderate methodological weaknesses. Sixteen of the 22 studies included studies were cluster control trials, and there was no mention by any of the researchers that cluster analysis was applied to any of the 16 studies. In addition to lack of cluster analysis, no process evaluation was conducted in any of the studies. Only one study performed an intention to treat analysis. Twelve studies experienced dropouts, but there was incomplete information on the study population at the end of the trial and the reason f or the dropouts. Additionally, none of the studies explained the theory upon which they based their intervention. There was also potential recruitment and selection bias in all the primary studies as identified by the reviewers. They stated that none of the studies reported the number of subjects that were approached for recruitment into the study. As none of the RCTs included described the method they used in randomization, neither did they state if the studies were blinded or not. The methodological flaws in a high percentage of the included primary studies could impact on the validity of the findings of the review. Again, the authors failed to reach a conclusion on the effectiveness of the interventions because of the intrinsic weaknesses found in the primary studies, and as a result state the need for more primary studies that would address the methodological weaknesses that is highly present in nearly all existing primary studies conducted on this topic so far. The study of the efficacy of school-based interventions aimed at preventing childhood obesity or reducing the risk factors is a rather complex one. Pertinent issues on effectiveness of school-based interventions to prevent the risk factors of obesity remain that there is very limited/weak evidence on which to base policies on. Heterogeneity of primary research (in terms if age of study population, duration of intervention, measurement of outcomes and outcomes measured) makes further statistical analysis nearly impossible. BMI is currently the most widely used measure of overweight and obesity in children. However, BMI has no way of distinguishing between fat mass and muscle mass in the body and might therefore misdiagnose children with bigger muscles as obese. Another disadvantage of using BMI in overweight measurement is its inability of depicting the body fat composition (Committee on Nutrition 2003), other surrogate indicators of adiposity may be needed. Most authors that have carried out a review on this topic so far have expressed the need for further research on this topic to add to the existing body of evidence. RATIONALE FOR THIS STUDY All the systematic reviews on this subject so far have focused mainly on the United States. Lifestyle differences such as eating habits between American and British children possibly affect generalisability and reproducibility of US findings to the UK. For example, in the US, research has shown that 0.5% of all television advertisements promote food, and that about 72% of these food advertisements promote unhealthy food such as candy and fast food (Darwin 2009). In the UK paradoxically, the government in 2007 enforced regulations banning television advertisement of unhealthy foods (foods with high fat, salt, and sugar content) during television programmes aimed at children below 16 years of age (Darwin 2009). Thus US children are at a higher risk of becoming obese than their UK counterparts as a result of higher rate of exposure to TV junk food advertisements. Another lifestyle difference between American and British children is physical activity. In the UK, a high percentage of children aged 2 to 15 achieve at least 60 minutes of physical activity daily (about 70% of males and 60% of females) (DoH 2004), as opposed to the US where only about 34% of school pupils achieve the daily recommended levels of physical activity daily (CDC 2008). These differences highlight the importance of public health policies being based on the local population characteristics rather than on imported overseas figures. There is therefore need to review the evidence of UK school-based obesity interventions to inform policy relevant to the UK population. To the best of my knowledge following an extensive literature search, no systematic review has been conducted on the effectiveness of school-based intervention in preventing childhood obesity in the UK, despite the high prevalence of the condition and its public health significance in this country. This research aims to bridge this gap in knowledge by focusing on UK based studies to evaluate the efficacy of school-based interventions in the UK population. This study therefore stands out insofar as it will be assessing the effectiveness of school-based interventions in the reducing the risk factors of obesity in the UK, with a hope of providing specific local recommendations based on UK evidence. This type of review is long overdue in the UK, considering that the governments target to reduce childhood obesity to its pre-2000 levels by the year 2020 (DoH 2007) will require local evidence of effective interventions to succeed. The next stage of this review will describe in detail the research methodology to be used to conduct the proposed systematic review. Also included will be research strategy details to be adopted, study selection criteria, data collection and analysis. AIMS AND OBJECTIVES The aim of this research is to: Systematically review school-based intervention studies in the UK aimed at reducing the risk factors of childhood obesity among school children. Objectives are: To assess the efficacy of school-based anti-obesity interventions in the UK. To identify the most effective form of school-based interventions in the prevention of childhood obesity amongst school children in the UK. CRITERIA FOR INCLUDING STUDIES IN THIS REVIEW METHODS This review was performed as a Cochrane review. The Cochrane guidance on systematic reviews and reporting format were as far as possible adhered to by the author (Green, Higgins et al. 2008). The entire review process was guided by a tool for assessing the quality of systematic reviews, alongside the accompanying guidance (health-evidence.ca 2007a; health-evidence.ca 2007b). TYPES OF STUDY In the search for the effectiveness of an intervention, well conducted randomised control trials (which are the best and most credible sources of evidence) will be the preferred source of studies for this review. However, because of the limited number of RCTs conducted on this topic so far, this study will include controlled clinical trials if there is insufficient availability of RCTs. TYPES OF PARTICIPANTS School children under 18 years of age TYPES OF INTERVENTIONS Interventions being evaluated are those that aim to: Reduce sedentary lifestyle Effect nutritional change Combine the two outcomes above Reduce obesity prevalence Effect an attitude change towards physical activity and diet Studies that present a baseline and post intervention measure of primary outcome. Interventions not included in this study are: Those with no specified weight-related outcomes Those that involved school-age children but were delivered outside of the school setting, as our focus is based on school-based interventions aimed at obesity prevention. Studies done outside the UK Studies with no specified interventions Non-RCTs or CCTs For each intervention, the control group will be school children not receiving the intervention(s). TYPES OF OUTCOMES MEASURED Primary outcomes Change in adiposity measured as BMI and/or skin fold thickness Secondary outcomes Knowledge Physical activity levels Diet SEARCH METHODS FOR IDENTIFICATION OF STUDIES Electronic searches The electronic databases OVID MEDLINE ® (1950-2009), PsycINFO (1982-2009), EMBASE (1980-2009) and the British Nursing Index (1994-2009) were all searched using the OVID SP interface. The Wiley Interscience interface was used to search the following databases: Cochrane Central Register of Controlled Trials and Database of Abstracts of Reviews of Effects. There was also a general search of internet using Google search engine, in an attempt to identify any ongoing studies or unpublished reports before proceeding to search grey literature sources. Grey literature For references to childhood obesity prevention in schools, the following grey literature sources were searched: British Library Integrated Catalogue (http://catalogue.bl.uk/F/?func=filefile_name=login-bl-list) ISI index of Conference Proceedings (http://wok.mimas.ac.uk/) SCIRUS (http://www.scirus.com/) System for Information on Grey Literature (http://opensigle.inist.fr/) ZETOC (http://zetoc.mimas.ac.uk) Additionally, current control trials database at http://www.controlled-trials.com/ was searched for any ongoing research. The UK national research register was also searched at https://portal.nihr.ac.uk/Pages/NRRArchive.aspx. All the links to the grey literature databases were tested at the time of this review and found to be working. Hand searches It was not possible to conduct a hand search of journals due to pragmatic reasons. Reference lists Reference lists of retrieved studies were searched for other potential relevant studies that might have been omitted in the earlier search. Correspondence First author of all included studies were contacted with a view to seeking more references. DATA COLLECTION AND ANALYSIS Selection of studies The abstracts and titles of the hits from the electronic databases searched were screened for relevance by a single assessor. Those that were thought to be potentially relevant were retrieved and downloaded unto EndnoteTM to make the results manageable and also avoid loss of data. At the end of the search, all databases were merged into one single database and duplicated records of the same study were removed. Subsequently, the assessor then sought and obtained the full text of, and reviewed the relevant studies that were considered eligible for inclusion. Multiple reports of same study were linked together. No further data were sought for studies not included in the review. Data extraction Data extraction from included studies was done by a single reviewer and the data recorded on a data extraction form. A summary of each included study was described according to these characteristics: Participants (age, ethnicity etc.), study design, description of school-based interventions, study quality and details such as follow-ups and date, location, outcomes measured, theoretical framework, baseline comparability and results Assessment of methodological quality of included studies A number of researchers (Jackson, Waters et al. 2005) and the Cochrane guidelines for systematic reviews of health promotion and public health interventions (Rebecca Armstrong, Waters et al. 2007) strongly advise using the Quality Assessment Tool for Quantitative Studies (2008a) developed by the Effective Public Health Practice Project in Canada and the accompanying dictionary (to act as a guideline) (2008b) in assessing methodological quality. Based on criteria such as selection bias, study design, blinding, cofounders, data collection methods, withdrawals and drop-outs and intervention integrity, the tool which is designed to cover any quantitative study employs the use of a scale (strong, moderate or weak) to assess the quality of each study included in the review. Analysis Considering the small number of studies included in the review and heterogeneity in terms of interventions, delivery methods, intensity of interventions, age of participants, duration of intervention and outcomes measured, it was not statistically appropriate to undertake a Meta analysis, which admittedly would have been the preferred method of analysing and summarising the results of the studies. A narrative synthesis of the results was done instead. RESULT DESCRIPTION OF STUDIES Results of the search The search of electronic sources identified 811 citations out of which 97 potential studies were retrieved. A reference management software EndnoteTM was used to search for and remove duplicate citations. Further screening of title and abstract reduced the number of citations to 17 potential studies. Full texts of the 17 studies were sought, 13 were excluded, and four met the inclusion criteria and were therefore included in the review. Authors of the four studies were then conta

Cultural Diversity in Business :: essays research papers

In their eagerness to avoid the courts and editorial pages, most firms in America, and increasingly in Europe, now pay close attention to the sex and race of the people they recruit and promote, For example, Harvard Business School has just announced that they will go out of its way to include women in its case studies, which are used in business-school classrooms around the world. In other words, schools and businesses, in order to stay out of trouble, are taking the easy way out, quotas. (Kole, MacDonald.1997.1) Although some women and minorities are hired to fill quotas, the majority of them are needed to create a cultural diverse workplace. Cultural Diversity can have a positive effect and be profitable but only for some firms. A well considered strategy must accompany Cultural Diversity if profit is to be made. There are at least two reasons to expect a policy of diversity to yield profits. One difference is communication. Because many people find it easier to understand others of the same sex, or nationality, it helps to have employees from the same cultural background as your customers. It’s not only a matter of language, but understanding the customer’s needs, tastes and the earning of their trust is vital. The recruiting of people from a different cultural background can not only improve communication with outsiders, it may also bring fresh ideas to insiders (Kole, MacDonald. 1997.2). Businesses don’t only need cultural diversity in order to relate to customers, they need women and minorities in management. Smaller banks have traditionally selected their directors from among those who live and work in their communities. Their reasoning is to hire people who cannot only tell the banks what the people want, but also spread the word about their products. However, many banks surveyed by the Business Times have local natives on their boards, few women are represented and almost no minorities can be found-even in areas where there is a large minority population (Kole,MacDonald.1997.2). Many bank CEO’s feel that the lack of minority and female representation needs to be corrected (Cochran.1997). â€Å"Jack Anderson, chairman and Chief Executive of Johnstown-based BT Financial Corp.- the holding company for Laurel Bank, and Johnstown Bank Trust Co. states â€Å"Any right-thinking person understands the need for diversity,† he said â€Å"I think it i s something we need to work toward.†(Neiser.1997.1)† Anderson also recognizes that there hasn’t been a large pool of candidates to choose from.

Biography of Jon Corzine

Jonathan Corzine was born on New Year’s Day in 1947 and grew up on his family’s farm in rural Illinois. Having learned the value of hard work from his parents, a farmer and a school teacher, he graduated from the University of Illinois at Urbana-Champaign as a Phi Beta Kappa and immediately enlisted in the Marine Reserves. He served for six years as a reservist while beginning his career in finance at the Continental Illinois National Bank. He earned his MBA in 1973 while attending night classes and went to work for Bank Ohio.He moved to New Jersey in 1975 with his wife when he went to work for the New York investment firm of Goldman Sachs where he was named partner in 1980 and CEO in 1984(About the Governor, 2006). The couple had three children, but later divorced (Governor’s Information, 2006). His affair became a public spectacle during his political career with his wife announcing that he may let down the state of New Jersey in the same way he let down the fa mily (Cilliza, 2005).However, this did not deter his political aspirations. Soon, Corzine entered the political spectrum. He made a push for the United States Senate and won the seat in 2000. Five years later, Corzine announced his intention of running for the New Jersey Governor. He focused on using his knowledge and skills in finance to help the economy of the state of New Jersey. As a Democrat, he urged the state to adopt a more progressive economic and social policy (Governor’s Information, 2006).He helped write the Sarbanes-Oxley Act, which attempted to crack down on corporate wrongdoing. He also sponsored the Start Healthy, Stay Healthy Act, which worked to create more health care coverage for children and pregnant women (Jon Corzine, 2008). His career was punctuated by his attempt to apply his business expertise to politics. In 2005, Corzine announced his candidacy for the governorship of New Jersey and vowed to utilize his business acumen which had helped him become a multimillionaire on Wall Street in helping out the state.â€Å"He built his campaign around his comprehensive ethics proposal, revamping the state’s property tax system, building a stronger economy, and improving education and healthcare†(Governor’s Information, 2006) Using 43 million dollars of his own money on the campaign, he narrowly beat his Republican adversary and became the 54th governor of New Jersey in January of 2007 (Cilliza, 2005). Corzine was sworn in as New Jersey’s 54th Governor on January 17, 2006.While in office, he worked hard to raise the sales tax from 6% to 7% even though he had to shut down the nonessential elements of government in order to do it. In addition, he abolished the death penalty in the state of New Jersey, replacing it with life imprisonment. He suffered a critical injury in a car accident in 2007, but has made a recovery and continues to serve his term. About the Governor. (2006). State of New Jersey Office of the Gov ernor.
