This study aimed to provide cost-effectiveness and budget impact analyses of a school-based overweight/obesity screening and care prevention strategy among adolescents.
Cost-effectiveness and budget impact analyses.
Data from 3538 adolescents who participated in a school-based randomised controlled trial in the Northeast of France were used. Costs (from a public payer's perspective) included screening for overweight and obesity and subsequent care. Effectiveness was measured as the change in body mass index (kilogram per square metre), prevalence of overweight/obesity, moderate physical activity energy expenditure, duration and frequency and total sitting time. The incremental cost-effectiveness ratio was calculated, and a budget impact analysis was conducted.
The screening and care strategy resulted in an incremental cost-effectiveness ratio of €1634.48 per averted case of overweight/obesity and €255.43 per body mass index unit decrease. The costs for increasing moderate physical activity by 1000 metabolic equivalent of task-min/week, duration by 60 min/week and frequency 1 day/week were €165.28, €39.21 and €93.66 per adolescent, respectively. Decreasing total sitting time by 60 min/week had a cost of €8.49 per adolescent. The cost of implementing the strategy nationally was estimated to be €50.1 million with a payback period from 3.6 to 7.3 years.
The screening and care strategy could be an efficient way to prevent overweight and obesity among adolescents. Future studies should investigate how the current results could be achieved in schools with different settings and thus justify its relevance for overweight and obesity prevention to policy-makers.
本研究旨在对一项针对青少年的基于学校的超重/肥胖筛查与预防策略进行成本效益分析和预算影响分析。
成本效益分析和预算影响分析。
使用了来自法国东北部3538名参与基于学校的随机对照试验的青少年的数据。成本（从公共支付者的角度）包括超重和肥胖筛查及后续护理。有效性通过体重指数（千克每平方米）的变化、超重/肥胖患病率、中等强度身体活动能量消耗、时长和频率以及总久坐时间来衡量。计算了增量成本效益比，并进行了预算影响分析。
筛查与预防策略导致每避免一例超重/肥胖病例的增量成本效益比为1634.48欧元，每体重指数单位降低的成本效益比为255.43欧元。每名青少年将中等强度身体活动增加1000代谢当量任务-分钟/周、时长增加60分钟/周以及频率增加1天/周的成本分别为165.28欧元、39.21欧元和93.66欧元。每名青少年每周将总久坐时间减少60分钟的成本为8.49欧元。在全国实施该策略的成本估计为5010万欧元，投资回收期为3.6至7.3年。
筛查与预防策略可能是预防青少年超重和肥胖的有效方法。未来的研究应调查在不同环境的学校中如何实现当前的结果，从而向政策制定者证明其对超重和肥胖预防的相关性。
