Objective

To assess the cost-effectiveness a school-based intervention designed to reduce overweight/obesity and other cardiovascular risk factors in children.

Methods

Standard cost effectiveness analysis methods and two perspectives (societal and institutional) were used. A cluster-randomized controlled trial with 10 intervention schools (691 children) and 10 control schools (718 children) was performed. Net costs were calculated by subtracting the usual after-school care cost from intervention costs. The effectiveness of the intervention was measured as the reduction in health outcomes compared with the control group.

Results

The intervention costs totaled 125,469.75鈧? representing 269.83 鈧?year/child. The usual after-school care was estimated at 844,56 鈧?year/child. Intervention children showed a decrease in triceps skinfold thickness (鈭?.25 mm, 95%CI: 鈭?.82 to 鈭?.67; P < .001). Intervention children with body mass index (BMI) between the percentiles 25 and 75 showed a decrease in the percentage of body fat (鈭?.59%; 95%CI: 鈭?.03 to 鈭?.67; P < .001), and those with a BMI > P75 showed a decrease in triceps skinfold thickness (鈭?.87 mm; 95%CI: 鈭?.43 to 鈭?.32; P < .001), and percentage of body fat (鈭?.67%; 95%CI: 鈭?.32 to 鈭?.01; P < .05).

Conclusions

This type of after-school program for recreational physical activity to prevent obesity are likely to be a cost-effective use of public funds and warrant careful consideration by policy makers and program planners.
