The global incidence of obesity is rising, posing a substantial public health threat. This meta-analysis aim to estimate of the prevalence of obesity among school-aged children in Vietnam and to analyze the risk variables that have been linked to this problem. MEDLINE, PubMed, and Scopus were used to identify articles published up to May 2022. According to peer-reviewed literature, studies reported the proportion of obesity among Vietnamese school-aged children. The Scales of Newcastle-Ottawa Quality Assessment was used to evaluate the study quality for all qualifying research. The data was analyzed using R-Studio software, and the combined effects were estimated using a random-effects model. Cochran's Q-test and the I2 test were employed to examine heterogeneity. Egger's test was used to determine publication bias. Eleven studies with 27,363 participants were suitable for inclusion in the final model after meeting the prerequisites. The proportion of obesity among Vietnamese school-aged children was 13.08% (95% CI, 7.04%–23.01%) with higher heterogeneity through the observed prevalence estimates (Q = 1,0339, p < 0.01, I2 = 99%). A higher prevalence was observed in boys (17.5%) than in girls (8.07%). Male gender of the children: 2.42 (95%CI: 1.43–4.09), mothers have less education: 2.63 (95% CI 1.52–4.55) have shown a positive association with the development of obesity among children. The recent pooled analysis of studies demonstrates that school-aged children in Vietnam have a high prevalence of obesity. The male gender and the low education status of the mother were found to be significantly associated with obesity. The findings provide evidence for prevention intervention strategies to reduce obesity in school-age children. •The recent pooled analysis of studies demonstrates that school-aged children in Vietnam have a high prevalence of obesity.•The prevalence of obesity was more in boys than in girls.•The male gender and the low education status of the mother were found to be significantly associated with obesity.
