Insights
This study designs a large-scale, multi-center school-based intervention to combat childhood obesity in China. It evaluates a comprehensive strategy against nutrition-only and physical activity-only interventions for cost-effectiveness.
Area of Science:
- Public Health
- Pediatrics
- Preventive Medicine
Background:
- Childhood obesity is a growing health concern in China, leading to metabolic and psychological issues.
- Early onset of cardiovascular diseases is linked to childhood obesity, necessitating effective interventions.
- School-based programs offer a practical approach to prevent and manage childhood obesity.
Purpose of the Study:
- To describe the design of a multi-centered, randomized controlled school-based clinical intervention for childhood obesity in China.
- To compare the cost-effectiveness of a comprehensive intervention strategy with nutrition education alone and physical activity alone interventions.
- To provide evidence for a potential national program to address childhood obesity.
Main Methods:
- A multi-centered randomized controlled trial involving 6 centers across China.
- Intervention includes nutrition education (carton-style handbook) and physical activity (Happy 10 program).
- 9750 primary students (grades 1-5) will undergo baseline and intervention measurements (anthropometrics, body composition, fitness, diet, physical activity, blood pressure, lipids, glucose).
Main Results:
- Data collection includes anthropometric measurements, body composition, physical fitness, dietary intake, physical activity levels, and biochemical markers.
- Cost data on staff training, materials, and school/supervising input will be gathered for cost-effectiveness analysis.
- The study is the largest multi-center comprehensive childhood obesity intervention in China.
Conclusions:
- The study's findings could support a national school-based program for childhood obesity prevention in China.
- A comprehensive intervention strategy may be more effective and cost-effective than single-focus approaches.
- This research addresses a critical public health issue with significant long-term implications.
Background:
Childhood obesity and its related metabolic and psychological abnormalities are becoming serious health problems in China. Effective, feasible and practical interventions should be developed in order to prevent the childhood obesity and its related early onset of clinical cardiovascular diseases. The objective of this paper is to describe the design of a multi-centred random controlled school-based clinical intervention for childhood obesity in China. The secondary objective is to compare the cost-effectiveness of the comprehensive intervention strategy with two other interventions, one only focuses on nutrition education, the other only focuses on physical activity.
Methods/Design:
The study is designed as a multi-centred randomised controlled trial, which included 6 centres located in Beijing, Shanghai, Chongqing, Shandong province, Heilongjiang province and Guangdong province. Both nutrition education (special developed carton style nutrition education handbook) and physical activity intervention (Happy 10 program) will be applied in all intervention schools of 5 cities except Beijing. In Beijing, nutrition education intervention will be applied in 3 schools and physical activity intervention among another 3 schools. A total of 9750 primary students (grade 1 to grade 5, aged 7-13 years) will participate in baseline and intervention measurements, including weight, height, waist circumference, body composition (bioelectrical impendence device), physical fitness, 3 days dietary record, physical activity questionnaire, blood pressure, plasma glucose and plasma lipid profiles. Data concerning investments will be collected in our study, including costs in staff training, intervention materials, teachers and school input and supervising related expenditure.
Discussion:
Present study is the first and biggest multi-center comprehensive childhood obesity intervention study in China. Should the study produce comprehensive results, the intervention strategies would justify a national school-based program to prevent childhood obesity in China.
