[Cost-effectiveness of an intervention to reduce overweight and XXXX in 9-10-year-olds. The Cuenca study].

@entity1 @entity28
OBJECTIVE: To assess the cost-effectiveness a school-based intervention designed to reduce overweight/ @entity28 and other cardiovascular risk factors in @entity1 . METHODS: Standard cost effectiveness analysis methods and two perspectives (societal and institutional) were used. A cluster-randomized controlled trial with 10 intervention schools (691 @entity1 ) and 10 control schools (718 @entity1 ) 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   , representing 269.83    /year/ @entity1 . The usual after-school care was estimated at 844,56    /year/ @entity1 . Intervention @entity1 showed a decrease in triceps skinfold thickness (-1.25mm, 95% CI: -1.82 to -0.67; P<.001). Intervention @entity1 with body mass index (BMI) between the percentiles 25 and 75 showed a decrease in the percentage of body fat (-0.59%; 95% CI: -1.03 to -0.67; P<.001), and those with a BMI>P75 showed a decrease in triceps skinfold thickness (-1.87mm; 95%CI: -3.43 to -0.32; P<.001), and percentage of body fat (-0.67%; 95%CI: -1.32 to -0.01; P<.05). CONCLUSIONS: This type of after-school program for recreational physical activity to prevent @entity28 are likely to be a cost-effective use of public funds and warrant careful consideration by policy makers and program planners.
