Meta Analysis the Effect of Intervention Based School toward Nutrition on Body Mass Index

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.
