![]() ![]() Therefore, at present, there is insufficient evidence to support a direct link between obesity and poor academic performance in school age children. After controlling for covariates such as socio-economic status, parental education and physical activity, the association between obesity and academic performance becomes uncertain for most of the studies (55.9%). Seven studies were classified as low risk of bias, 23 as medium risk and four as high risk. Thirty-four studies (23 cross-sectional and 11 longitudinal) matched all inclusion criteria and were included. Risk of bias was assessed by using Strengthening the Reporting of Observational Studies in Epidemiology. Cross-sectional and longitudinal studies examining the association between obesity and academic performance in children and adolescents, published between January 1990 and December 2016, were included. A systematic review of English articles was undertaken by using databases PubMed/Medline, ERIC, LILACS, SciELO and Web of Science. The aim of this study was to systematically review the scientific evidence on the association between obesity and academic performance in school children. Previous studies have found that obesity could influence academic performance. Psychosocial variables, such as weight-based teasing, should be considered in future research examining the impact of childhood obesity on school performance and in future intervention studies. Weight-based teasing was significantly associated with school performance, with lower odds of strong school performance among weight-based teased children (OR=0.44 95% CI=0.27, 0.74). However, the addition of weight-based teasing to the model (with weight category and covariates) reduced the weight category parameter estimate by 24%, becoming non-significant (OR=1.40 95% CI=0.93, 2.10) and indicating a possible mediating effect of weight-based teasing on the relationship between weight category and school performance. #Mical se burla de david freeOverweight status was a significant predictor of poorer school performance (OR=1.51 95% CI=1.01, 2.25), after adjustment for gender, school level, free and reduced lunch participation, and race. Overweight status (body mass index > 85th percentile for gender and age) and weight-based teasing were examined as predictors of poorer school performance. Random parental telephone survey data (N=1 071) of public school students collected as part of the statewide evaluation of Arkansas Act 1220, a law to reduce childhood obesity, were used. ![]() Psychosocial factors, such as weight-based teasing, have been proposed as having a possible mediating role, although they remain largely unexplored. School performance of overweight children has been found to be inferior to normal weight children however, the reason(s) for this link between overweight and academic performance remain unclear. ![]()
