OBJECTIVES: To identify the South American prevalence of overweight and obesity in children and adolescents from 2010 to 2020. METHODS: A systematic literature search was conducted in PubMed, SCOPUS, LILACS, IBECS and, MedCarib databases. Only cross-sectional, cohort, case-control and clinical trials studies were included. The methodological quality of the studies was assessed independently by two review authors, using the Newcastle-Ottawa scale. Random effect model by DerSimonian and Laird and inconsistency measure (I2) were used. RESULTS: In total, 532 articles met the inclusion criteria. 88 studies were included in the analysis and 80 were classified as high quality/low bias. The prevalence was: 28.3% (95% confidence interval [CI95%]=22.4;34.2% - I2=99.98%) of excess body weight, 17.8% of overweight (CI95%=14.3;21.3% - I2=99.94%) and 13.2% (CI95%=10.1;16.3% - I2=99.96%) of obesity. CONCLUSION: The South American prevalence of overweight was 17.8% and obesity was 13.2%. Meta-analysis showed high heterogeneity (I2>99%) probably due to the ethnic, cultural and methodological differences. |
