摘要

简介:夏令营(SDC)可以通过提供一个促进健康行为的结构化日常环境来减轻夏季体重增加,但对于低收入家庭来说,SDC的成本往往过高。本研究评估了为弱势儿童提供免费SDC以防止夏季体重增加的成本效益。方法:从南卡罗来纳州的一个低收入学区招募422名儿童,随机分配接受8-10周的免费SDC或在2021-2023年像往常一样体验夏季。增量成本-效果比(ICER)通过SDC成本除以干预组和对照组从夏初到夏末身体质量指数z分数(zBMI)变化的差异来计算。还计算了参与SDC的不同剂量下的ICERs。使用基于试验的zBMI结果的非参数自助方法进行敏感性分析,并与全国各地的SDC成本相匹配。成本效益的可能性是根据政策制定者可能愿意支持的一系列潜在成本来评估的。结果:与对照组相比,SDC代金券项目以1307美元的成本避免了0.0917个zBMI的增加,每减少0.1个zBMI,每个儿童的成本为1463美元。每周5天参加SDC,最高剂量,产生最高的成本效益。敏感性分析显示,自我引导的ICERs平均每避免0.1 zBMI花费2187美元,其中80%的ICERs每避免0.1 zBMI花费不到3500美元。结论:代金券计划可能具有成本效益,如果政策制定者愿意为每减少0.1 zBMI支付3,500美元,则成本效益的可能性为80%。

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.
