Anthropometric characteristics and obesity prevalence at baseline, after intervention and changes in different groups^.

^ Continuous variables were expressed as mean±standard error.a, b: Means shared the different letter means significant difference at baseline among groups in Beijing, pc, d : Means shared the different letter means significant difference of changes (post-intervention vs. baseline) among groups in Beijing, p* Comparison the mean between post-intervention and baseline in each group, p# Comparison means between combined intervention group and control group at baseline as well as for changes (post-intervention vs. baseline), # p## p† OR and 95% CI for overweight & obesity prevalence using generalized linear mixed model, no significantly difference of OR between nutrition or PA individual intervention group with their control group, but a borderline difference between combined intervention group with its’ control group (p=0.06).
