Chinese multi-centered school based obesity intervention
Brief summary
The study was designed as a national multi-centered cluster randomized controlled trial involving more than 70,000 children and adolescents aged 7-18 years from 7 provinces in China. In each center, about 12-16 primary and secondary schools, with totally at least 10000 participants were randomly selected (Primary: Secondary=1:1). All of the selected schools were randomly allocated to either intervention or control group (Intervention: Control=1:1).The multi-components school-based and family-involved scheme was conducted within the intervention group for 9 month, while students in the control group followed their usual health practice. The intervention consisted of four components: a) Create supportive school and family environment, b) Health lifestyles education and related compulsory physical activities, c) Instruct and promote school physical education, d) Self-monitor obesity related behaviors. Four types of outcomes including anthropometric, behavioral, blood chemical and physical fitness were measured to assess the effectiveness of the intervention program.
