“…Data entered in RevMan included the following: pre/post-changes in outcome measures for the intervention and the control groups, the corresponding number of participants for each treatment group in the trial and standard deviation (s). Where studies 38,39,51,55,56 reported mean changes in outcome measures from baseline (pre) to end point (post) for each intervention group (that is, DI or DC), data were entered in RevMan with their corresponding number of participants and s's. For trials 40,41,43,44,46 that reported both pre-and post-intervention values, changes were computed by subtracting the pre-from the post-measurements.…”

“…Given that intervention components vary considerably across studies, it is not possible to do so definitively; however, several salient considerations emerge from this review. An assessment limited to the findings of formal meta-analysis suggests that the following commonly used program components may be valuable: parent involvement (as discussed above), [37][38][39][40][41]43,44 classroom (or after-school) instruction on improving dietary intake or increasing PA, [37][38][39][40][41]43,44,46,49 participatory/hands-on, skill building student activities, [37][38][39][40][41]43,44,49 the provision of print materials, [37][38][39][40] teacher training for program implementation, 37-39 student competitions, 44 improvements to the nutritional environment (school cafeteria offerings, etc. ), 43,46 implementation of PA programs in addition to routine PE, 40,41,43 modifications to duration, frequency or intensity of existing PE, 46,49 use of non-competitive PA, 49 training in behavioral techniques (including self monitoring, goal setting, etc.)…”

Objective: To determine the effectiveness of school-based strategies for obesity prevention and control using methods of systematic review and meta-analysis. Methods: Peer-reviewed studies published between 1966 and October 2004 were considered for review. Studies meeting eligibility criteria were published in English, targeted children aged 3-18 in a school setting, reported weight-related outcomes, included a control measurement and had at least a 6-month follow-up period. Studies employed interventions related to nutrition, physical activity, reduction in television viewing or combinations thereof. Weight related data were analyzed using RevMan software. Results: Sixty-four studies were considered for inclusion. Fourteen did not meet inclusion criteria; 29 were excluded due to poor methodological quality. Twenty-one papers describing 19 studies were included in the systematic review and 8 of these were included in the meta-analysis. Nutrition and physical activity interventions resulted in significant reductions in body weight compared with control ((standardized mean difference, SMD ¼ À0.29, 95% confidence interval (CI) ¼ À0.45 to À0.14), random effects model). Parental or family involvement of nutrition and physical activity interventions also induced weight reduction ((SMD ¼ À0.20, 95%CI ¼ À0.41 to 0.00), random effects model). Conclusion: Combination nutrition and physical activity interventions are effective at achieving weight reduction in school settings. Several promising strategies for addressing obesity in the school setting are suggested, and warrant replication and further testing.

Background Obesity prevention is an international public health priority. The prevalence of obesity and overweight is increasing in child populations throughout the world, impacting on short and long-term health. Obesity prevention strategies for children can change behaviour but efficacy in terms of preventing obesity remains poorly understood. Objectives To assess the effectiveness of interventions designed to prevent obesity in childhood through diet, physical activity and/or lifestyle and social support. Search strategy MEDLINE, PsycINFO, EMBASE, CINAHL and CENTRAL were searched from 1990 to February 2005. Non-English language papers were included and experts contacted. Selection criteria Randomised controlled trials and controlled clinical trials with minimum duration twelve weeks. Data collection and analysis Two reviewers independently extracted data and assessed study quality. Main results Twenty-two studies were included; ten long-term (at least 12 months) and twelve short-term (12 weeks to 12 months). Nineteen were school/preschool-based interventions, one was a community-based intervention targeting low-income families, and two were familybased interventions targeting non-obese children of obese or overweight parents. Six of the ten long-term studies combined dietary education and physical activity interventions; five resulted in no difference in overweight status between groups and one resulted in improvements for girls receiving the intervention, but not boys.
