The Cost Effectiveness of a Free Summer Day Camp Voucher Program to Prevent Summer Weight Gain among Children from Disadvantaged Households.
Introduction: Summer day camps (SDC) can mitigate summer weight gain by providing a structured daily environment that promotes healthy behaviors, but SDCs are often cost prohibitive to families with low-income. This study evaluated the cost effectiveness of providing free SDC to disadvantaged children to prevent summer weight gain.
Methods: 422 children from a low-income school district in South Carolina were recruited and randomly assigned to receive 8-10 weeks of free SDC or to experience summer as usual in 2021-2023. The incremental cost-effectiveness ratio (ICER) was calculated by dividing SDC cost by the difference between the intervention and control groups in changes in Body Mass Index Z-scores (zBMI) from the start to end of summer. ICERs at different doses of SDC participation were also calculated. Sensitivity analyses were conducted using nonparametric bootstrapping of trial-based zBMI outcomes, matched with SDC costs from across the country. The probability of cost-effectiveness was assessed over a range of potential costs at which policymakers may be willing to support.
Results: The SDC voucher program averted 0.0917 zBMI gain relative to control at a cost of $1,307, yielding an ICER of $1,463 per 0.1 zBMI averted per child. Attending SDC 5 days per week, the highest dose, yielded the highest cost-effectiveness. Sensitivity analyses showed the bootstrapped ICERs averaged $2,187 per 0.1 zBMI averted, with 80% being less than $3,500 per 0.1 zBMI averted.
Conclusion: The voucher program is likely cost effective, with 80% probability of cost-effectiveness if policymakers are willing to pay $3,500 per 0.1 zBMI averted.
期刊介绍:
The American Journal of Preventive Medicine is the official journal of the American College of Preventive Medicine and the Association for Prevention Teaching and Research. It publishes articles in the areas of prevention research, teaching, practice and policy. Original research is published on interventions aimed at the prevention of chronic and acute disease and the promotion of individual and community health.
Of particular emphasis are papers that address the primary and secondary prevention of important clinical, behavioral and public health issues such as injury and violence, infectious disease, women''s health, smoking, sedentary behaviors and physical activity, nutrition, diabetes, obesity, and substance use disorders. Papers also address educational initiatives aimed at improving the ability of health professionals to provide effective clinical prevention and public health services. Papers on health services research pertinent to prevention and public health are also published. The journal also publishes official policy statements from the two co-sponsoring organizations, review articles, media reviews, and editorials. Finally, the journal periodically publishes supplements and special theme issues devoted to areas of current interest to the prevention community.
