Cost-Effectiveness Analysis of a Comprehensive Obesity Prevention Program
Overview
The DECIDE-Children intervention, a multi-component program in Chinese primary schools, demonstrated significant reductions in childhood obesity and was found to be cost-effective. The program's economic evaluation suggests it is a viable strategy for addressing the rising prevalence of obesity among school-aged children.
Background
Childhood obesity is a pressing global health issue, particularly in low- and middle-income countries like China, where rates have surged dramatically. The associated health risks and economic burdens underscore the need for effective prevention strategies. School-based interventions, especially those that engage families and incorporate multiple components, have shown promise in combating this epidemic.

BMI
-0.46 kg/m² (95% CI -0.67 to -0.25)
0.34 (95% CI 0.18 to 0.64)
Key Findings
The DECIDE-Children intervention reduced BMI by a mean of -0.46 kg/m².
The intervention significantly lowered the odds of obesity with an odds ratio of 0.34.
Cost-effectiveness analysis indicated an incremental cost-utility ratio of approximately US$4,644 per QALY gained.
The program's cost was about US$19.5 per student.
Multi-component interventions are more effective than single-component approaches in preventing childhood obesity.
Clinical Implications
Healthcare professionals should consider the integration of family engagement and multi-component strategies in obesity prevention programs. The cost-effectiveness of the DECIDE-Children intervention highlights its potential for broader implementation in school settings to combat childhood obesity.
Conclusion
The DECIDE-Children intervention presents a promising model for addressing childhood obesity through effective and cost-efficient strategies. Its successful implementation could inform future public health policies aimed at reducing obesity rates in children.
