The objective of this study was to determine the prevalence and associated factors of overweight/obesity among urban primary and secondary school children. This was a descriptive cross-sectional study among school children and adolescents (n=1442) selected using multistage sampling method. Behavioral data were collected using a structured self-administered questionnaire with parents of children aged 6–18 years old studying in schools of Kinshasa. Height and weight measurements of 575 children were taken and BMI for-age-sex was calculated using WHO AnthroPlus. Data were analyzed using SPSS version 21. Associated factors were examined using Chi-square tests followed by multivariate logistic regression analyses

The study found that out of 1442 students, 72 % of the sample was at a healthy weight, 15% were underweight and nearly 13% were overweight or obese. The prevalence of overweight and obesity was higher in older students as compared to younger students and in older girls as compared with older boys. Younger age group children were much more likely to be underweight. The results of multivariate logistic regressions showed that the sex of children, category of age, %BF, eating fruits and vegetables, physical activity were significantly associated with childhood overweight/obesity. One in eight children and adolescents aged of 6 to 18 years (12.8%) in Kinshasa going to primary and secondary schools were either overweight or obese. As the prevalence of overweight and obesity is increasing in the DRC, early interventions on these modifiable risk factors are likely to reduce the rate of childhood obesity
