[Evaluation on the effectiveness of intervention comprehensive program on child obesity, using Generalized Estimating Equation].

Objective: To evaluate the effect of child obesity intervention comprehensive program on the improvement of overweight, obese control and knowledge-attitude-practice.
Methods: The study design was under cluster-randomized controlled trial, with 965 children in the intervention and 895 children in the control groups. Repeated measurement data on child obesity was analyzed through Generalized Estimating Equation models.
Results: The risk of becoming overweight or obesity in the intervention group was 0.824 times more than children in the control group, showing a reduction of 17.6% the risk of being overweight or obese (P = 0.031). In addition, the possibility of increasing one unit of correct rate on obesity related knowledge, children in the intervention group children was 1.044 times (P = 0.001)than in the control group. On the mean obesity related correct attitude rate, it was 1.023 times (P = 0.001) in the intervention group of the control group. Regarding the possibility of increasing one unit om the mean obesity related behavior score, children in the intervention group was 1.522 times (P = 0.001)than those in the control group (P = 0.046).
Conclusion: The comprehensive child obesity intervention program could effectively reduce the risk of developing overweight or obesity and improving the obesity related knowledge, attitude and behavior in children.
