“…These findings highlight the paucity of high-quality, theory based interventions to mitigate the effects of overweight and obesity, and energy-related behaviours among African children. A considerable body of evidence suggests that multicomponent school-based interventions that target PA, dietary behaviours, sedentary behaviours, and the environments are more likely to be effective in children and adolescents compared with single component interventions [15][16][17][18]34]. Given the multi-faceted nature of overweight and obesity, it is not surprising that programmes that target individual behaviours and the obesogenic environments simultaneously are promising.…”

Background: Overweight/obesity is an emerging health concern among African children. The aim of this study was to summarise available evidence from school-based interventions that focused on improving nutrition and physical activity knowledge, attitude, and behaviours, and weight status of children aged 6-15 years in the African context. Methods: Multiple databases were searched for studies evaluating school-based interventions of African origin that involved diet alone, physical activity alone, or multicomponent interventions, for at least 12 weeks in duration, reporting changes in either diet, physical activity, or body composition, and published between 1 January 2000 and 31 December 2018. No language restrictions were applied. Relevant data from eligible studies were extracted. Narrative synthesis was used to analyse and describe the data. Results: This systematic review included nine interventions comprising 10 studies. Studies were conducted among 9957 children and adolescents in two African countries, namely South Africa and Tunisia, and were generally of low methodological quality. The sample size at baseline ranged from 28 to 4003 participants. Two interventions reported enrolling children from both urban and rural areas. The majority of the study participants were elementary or primary school children and adolescents in grades 4 to 6. Participants were between the ages of 12.4 and 13.5 years. All but one intervention targeted children of both sexes. Four studies were described as randomised control trials, while five were pre-and post-test quasi-experiments. Except for one study that involved the community as a secondary setting, all were primarily school-based studies. The duration of the interventions ranged from four months to three years. The interventions focused largely on weight-related behaviours, while a few targeted weight status. The results of the effectiveness of these interventions were inconsistent: three of five studies that evaluated weight status (body mass index (BMI), BMI z-score, overweight/obesity prevalence), three of six studies that reported physical activity outcomes (number of sports activities, and physical activity duration ≥ 30 min for at least six days/week), and four of six reporting on nutrition-related outcomes (number meeting fruit and vegetable intake ≥ 5 times/day) found beneficial effects of the interventions. Conclusion: Given the dearth of studies and the inconsistent results, definite conclusions about the overall effectiveness and evidence could not be made. Nonetheless, this study has identified research gaps in the childhood obesity literature in Africa and strengthened the need for further studies, the findings of which would contribute valuable data and inform policy.

“…La escuela es un escenario adecuado para realizar intervenciones contra la obesidad, porque es donde los escolares pasan gran parte de su tiempo, toman algunas de las comidas y son educados de manera natural sobre estilos de vida saludables; además, junto al ámbito familiar son los espacios educativos que más influyen en la adquisición de hábitos alimentarios y estilos de vida saludable (7,2) .…”

Evaluación del impacto de la intervención educativa-motivacional "Como jugando" para prevenir la obesidad en escolares del Cercado Conclusiones. La intervención "Como Jugando", al primer año de implementación, no redujo el Puntaje Z del IMC, sin embargo, tuvo impacto sobre los conocimientos en nutrición, redujo la probabilidad de tener un nivel malo de actividad física y mantuvo o aumentó la frecuencia adecuada del consumo de frutas, agua sin azúcar, jugos envasados y galletas dulces y saladas. Es necesario continuar evaluando la intervención "Como Jugando" para estimar el impacto sobre indicadores biológicos.

IMPACT EVALUATION OF EDUCATIONAL-MOTIVATIONAL INTERVENTION "COMO JUGANDO" TO PREVENT OBESITY IN SCHOOL CHILDREN OF CERCADO DE LIMA: RESULTS IN THE FIRST YEAR ABSTRACTObjective. To determine the impact of the educational-motivational intervention "Como jugando" on the body mass index (BMI), knowledge on nutrition, physical activity levels, and eating patterns in students from the first to fourth grades of four educational institutions (EIs) of Cercado de Lima after the first year of the intervention. Materials and methods. This was a quasi-experimental, controlled study. BMI, knowledge on nutrition, frequency of food consumption, and level of physical activity were evaluated. The "Como jugando" program included playful and experiential activities for school children and involved both teachers and parents. The impact was estimated by applying the McNemar test for related samples and regression models for the analysis of differences in adjusted variables related to children and their mothers. Results. The study included 696 school children from two experimental EIs and two control EIs. The Z-score for BMI and the prevalence of obesity did not vary during the study period. The intervention improved the knowledge of nutrition [odds ratio (OR): 1.46; 95% confidence interval (CI): 1.17-1.81], reduced the likelihood of poor levels of physical activity (OR: 0.63; 95% CI: 0.46-0.87), and improved the consumption patterns for all food categories except vegetables in the intervention group. Conclusions. The "Como jugando" intervention, in the first year of implementation, did not reduce the Z-score for BMI but improved the knowledge of nutrition, reduced the probability of poor levels of physical activity, and maintained or increased the consumption of fruits, sugar-free water, packaged juices, and sweet and savory cookies. Therefore, the "Como jugando" intervention should be better studied in order to estimate its impact on biological indicators.

“…Five systematic reviews included both randomized controlled trials (RCTs) and studies that were not randomized or did not include a control and two reviews included RCTs only. Four systematic reviews synthesized results using meta‐analysis, and four undertook a systematic search but described the findings using narrative review . No values were reported in the papers using narrative review; therefore, these are considered in terms of reported significance of effect.…”

This systematic review of systematic reviews addresses a current gap in evidence by synthesizing findings relating to weight management interventions set entirely in primary/elementary schools targeting, diet, and/or physical activity as key strategies.Eight databases were searched for systematic reviews of trials of school-based interventions targeting children aged 4 to 12 years that looked at biometric and behavioral outcomes. From the 10 selected systematic reviews, we found that interventions designed to promote physical activity or reduce sedentary behavior were most effective for weight loss. Interventions designed to improve diet and nutrition had a small effect on behavioral and cognitive outcomes, and these outcomes could be enhanced through the use of experiential learning. The most effective interventions involved a range of stakeholders in the development process and included parents and families in implementation. This systematic review of systematic reviews offers evidence-based guidance for the development and implementation of multistrategy weight-management interventions in primary/elementary schools. K E Y W O R D S Childhood obesity, primary/elementary schools, systematic review 1 | INTRODUCTION Being overweight in childhood is associated with poorer quality of life 1 and excess morbidity and mortality in adulthood. 2 Research in the UK shows that BMI has been increasing among children entering reception class (aged 4/5) and accelerating through to the last year of primary school (year 6, aged 10/11 years). 3 This suggests that intervention with school-aged children should take place as early as possible, and the primary school setting offers a key opportunity to intervene early, at a crucial time in children's development. Early intervention has the potential to have short and long-term effects on a number of health, educational, and social outcomes 4 and to reduce health inequalities globally. 5 The aim of the present research was to review systematically what is known about the effectiveness and contents of primary/elementary school-based interventions to prevent or treat excess weight gain.Weight-management interventions are increasingly being evaluated in school settings, and subsequently the amount of research published on this topic, including reviews of reviews, has increased. 6,7 It is difficult to draw firm conclusions from these previous reviews of reviews on three grounds. First, they have generalized across children from early childhood to adolescence, at all stages of their schooling, 8 which is problematic because BMI naturally increases with age. 1 Second, previous reviews of reviews have focused on specific obesityprevention single strategies such as increasing physical activity in
