Simple random sampling proportionate to each of the schools population size was used to select the children. A child’s anthropometric data, which was converted to Weight – for- Height z-scores, was used to determine the prevalence of overweight and obesity. A structured questionnaire was used to collect data. Anthropometric data was analyzed using WHO anthro software for child standards in monitoring and growth. Data was analyzed using SPSS version 12.0 and Epi Info version 3.4.3. Chi-square test of association and logistic regression (binary) was used to determine the significant variables affecting the prevalence of overweight and obesity. All p values <0.05 were considered to be statistically significant. Results indicated that the prevalence of overweight was 13.4% and obesity 6.9%.
