Abstract
Background: Body mass index (BMI) is a metric used to define anthropometric characteristics and classify interpretations of individual fatness indexes. The International Association For The Study Of Obesity (IASO) and the International Obesity Task Force (IOTF) calculate that 200 million school children worldwide are overweight or obese. This study aims to estimate the magnitude of the effect of school-based interventions for nutrition on body mass index based on a number of previous primary studies. Subjects and Method: This study is a systematic study and meta-analysis, with the following PICO Population = students (SMP) and (SMA) with obesity. Intervention= School-based interventions for nutrition. Comparison= no intervention. Outcomes in the form of body mass index. The articles used in this study were obtained from several databases, including PubMed, ScienceDirect, and Google Scholar. This article was collected for 1 month. The keywords to search for articles were as follows: “School-based intervention” AND “Nutrition ” “AND “ Obesity “ AND “BMI” OR “Body Mass Index” AND “Randomized Controlled Trial”. The articles included in this study are full-text articles with a Randomized Controlled Trial study design. Articles were collected using PRISMA flow diagrams. Articles were analyzed using the Review Manager 5.3 application Results: A total of 9 articles were reviewed in this meta-analysis. The study showed that school-based interventions for nutrition had an effect on lowering body mass index (Standardized Mean Difference = -0.23; 95% CI = -0.39 to 0.007 p= 0.005). Conclusion: School-based interventions for nutrition lower body mass index. Keywords: school-based interventions, nutrition, obesity, Body mass index . Correspondence: Wulandari.
