Abstract: Objective: The purpose of this systematic review is to investigate the effectiveness of school lunch programs for reducing childhood obesity by examining changes to the Body Mass Index (BMI) as an outcome measure to compare and assess the effectiveness of different school lunch interventions. Background: Childhood obesity has a high likelihood of leading to obesity in adulthood and this negative effect is well documented. School lunches have been widely implemented in this decade for tackling childhood obesity. Many countries are following this trend to align school lunches with national or standard nutrition guidelines as part of the school policy. Since many schools have only recently started to provide school lunches, the impact of these programs in terms of reducing childhood obesity has yet to be fully explored. Methods: Published literature about school lunch and body mass index from 2008 to 2014 was collected through PubMed and ScienceDirect. Relevant studies, including cohort studies, cross-sectional studies, case control studies, and observational studies, were included if they involved interventions that measured BMI as an independent outcome. Results: Nine studies from USA and one from Norway were included in this systematic review. For measuring school lunch participation, 4 were associated with increased BMI after intervention, 1 was associated with decreased BMI and 3 were not statistically significant with BMI. For studies that included consumption or observed energy intake, 3 were associated with lower BMI and 1 study showed that higher consumption lowered initial BMI but increased BMI over time. Overall, the results were inconsistent, and this may be attributed to confounding factors such as different food environments, meal quality, and availability of school snacks. Conclusion: The implications for school lunch programs as a key factor in lowering childhood obesity are complicated. No solid conclusions can be inferred for the effectiveness of school lunch program for lowering childhood obesity, as certain studies show positive relationships and others show no association. Future research with primary data and longitudinal cohort with years follow up may be considered for studying the relationship of between the school lunch program and the trend of BMI of children change at each level of school. Research on extending observed energy intake should also be applied in order to provide guidance for policy change on the meal quality, food options, competitive foods availability as well as nutrition guidelines.

Book Description
This report presents the outcomes of a scoping review conducted to identify and map existing evidence on the effects of school food and nutrition policies on health-related outcomes in children of school age as part of the initial preparation for undertaking the guideline development process by the WHO Nutrition Guidance Expert Advisory Group (NUGAG) Subgroup on Policy Actions. In order to align with WHO’s Nutrition-friendly Schools Initiative (NFSI) framework, school-based food and nutrition interventions were assessed in terms of the impacts in four key policy areas, namely – the school community, the school curriculum, the school food and nutrition environment, and school nutrition and health services.

Abstract: Objective: To systematically review the feasibility and effectiveness of recent school lunch interventions in primary schools and whether they instil positive changes to childhood dietary habits and help prevent obesity. Background: Childhood obesity is a growing concern affecting 42 million children (2010) and increasing daily, and may be linked to adult obesity. Lunch contributes 24% of daily energy, making school lunch interventions monumentally important in reducing consumption of high fat and/or sugar foods, and increasing fruit and vegetable (F&V) intake. Methods: A literature search was conducted for studies with interventions in primary school environments that aimed to alter the consumption of fruits, vegetables, and unhealthy foods high in fat or sugar. Studies were only suitable if they utilized randomized controlled trial (RCT) or cluster RCT designs, and included relevant outcome measures for F&V or macronutrient consumption. Relevant studies published between January 1st 2000 and May 31st 2013 were identified through PubMed, ISI Web of Science, and Cochrane Trials, and bibliographies of relevant studies. Results: Nine studies were included in this systematic review from the US or UK, with varied direct and indirect interventions to alter school lunch nutrition either through F&V or improved macronutrient content. Environmental changes to child attitudes towards F&V, such as verbal encouragement, classroom curriculums and audio-visual stimuli, were significantly effective in all 4 studies, whereas 2 studies with changes to F&V availability without involving students had mixed results. Direct reductions to fat content in school lunches produced significant results in 2 of 4 studies, with increased carbohydrate intake compensating for lower fat, resulting in non-significant total energy changes. One of 3 environmental interventions also had similar trends in macronutrient intake. Total energy change was only significant in 1 of 6 studies. Conclusion: Overall interventions for childhood obesity had moderate success, and most were unable to meet primary dietary goals set out by researchers. Ineffectiveness of interventions may be due to parental influences at home, early childhood dietary habits, disproportionately low SES in study samples, among other factors. Further research on targeting calorie intakes, parental involvement, snack food reduction, and related fields is recommended.

Book Description
Children's health has made tremendous strides over the past century. In general, life expectancy has increased by more than thirty years since 1900 and much of this improvement is due to the reduction of infant and early childhood mortality. Given this trajectory toward a healthier childhood, we begin the 21st-century with a shocking developmentâ€"an epidemic of obesity in children and youth. The increased number of obese children throughout the U.S. during the past 25 years has led policymakers to rank it as one of the most critical public health threats of the 21st-century. Preventing Childhood Obesity provides a broad-based examination of the nature, extent, and consequences of obesity in U.S. children and youth, including the social, environmental, medical, and dietary factors responsible for its increased prevalence. The book also offers a prevention-oriented action plan that identifies the most promising array of short-term and longer-term interventions, as well as recommendations for the roles and responsibilities of numerous stakeholders in various sectors of society to reduce its future occurrence. Preventing Childhood Obesity explores the underlying causes of this serious health problem and the actions needed to initiate, support, and sustain the societal and lifestyle changes that can reverse the trend among our children and youth.

Book Description
The World Health Organization estimates that there are 2.1 billion individuals with obesity globally. Nearly three quarters of adults in the United States are overweight or obese. The average individual with obesity cuts ten years off their life expectancy, yet less than 40% of physicians routinely counsel individuals concerning the adverse health consequences of obesity. Obesity Prevention and Treatment: A Practical Guide equips healthcare practitioners to include effective weight management counselling in the daily practice of medicine. Written by lifestyle medicine pioneer and cardiologist, Dr. James Rippe and obesity expert Dr. John Foreyt, this book provides evidence-based discussions of obesity and its metabolic consequences. A volume in the Lifestyle Medicine Series, it provides evidence-based information about the prevention and treatment of obesity through lifestyle measures, such as regular physical activity and sound nutrition, as well as the use of new medications or bariatric surgery available to assist in weight management. Provides a framework and practical strategies to assist practitioners in safe and effective treatments of obesity. Contains information explaining the relationship between obesity and increased risk of heart disease, diabetes, cancer, osteoarthritis, and other chronic conditions. Chapters begin with bulleted key points and conclude with a list of Clinical Applications. Written for practitioners at all levels, this user-friendly, evidence-based book on obesity prevention and treatment will be valuable to practitioners in general medicine or subspecialty practices.
