To examine the cost-effectiveness of Be Active Eat Well (BAEW), a large, multifaceted, community-based capacity-building demonstration program that promoted healthy eating and physical activity for Australian children aged 4-12 years between 2003 and 2006.
A quasi-experimental, longitudinal design was used with anthropometric data collected at baseline (1001 children-intervention; 1183-comparator) and follow-up. A societal perspective was employed, with intervention resource use measured retrospectively based on process evaluation reports, school newsletters, reports, and key stakeholder interviews, and valued in 2006 Australian dollars (AUD). Outcomes were measured as Body Mass Index (BMI) units saved and Disability Adjusted Life Years (DALYs) averted over the predicted cohort lifetime, and reported as incremental cost-effectiveness ratios (with 95% uncertainty intervals).
The intervention cost AUD0.34M ($0.31M; $0.38M) annually, and resulted in savings of 547 (-104; 1209) BMI units and 10.2 (-0.19; 21.6) DALYs. This translated to modest cost offsets of AUD27 311 (-$1803; $58 242) and a net cost per DALY saved of AUD29 798 (dominated; $0.26M).
BAEW was affordable and cost-effective, and generated substantial spin-offs in terms of activity beyond funding levels. Elements fundamental to its success and any potential cost efficiencies associated with scaling-up now require identification.
评估 Be Active Eat Well（BAEW）的成本效益。BAEW 是一个大型的、多方面的、基于社区的能力建设示范项目，旨在促进澳大利亚 4-12 岁儿童的健康饮食和身体活动，该项目于 2003 年至 2006 年实施。
采用准实验、纵向设计，在基线（1001 名干预组；1183 名对照组）和随访时收集人体测量数据。采用社会视角，根据过程评估报告、学校通讯、报告和主要利益相关者访谈，回顾性地衡量干预资源的使用情况，并以 2006 年澳元（AUD）计价。结果以预计队列寿命内节省的体重指数（BMI）单位和避免的残疾调整生命年（DALY）衡量，并报告为增量成本效益比（95%置信区间）。
干预每年花费 AUD0.34 百万澳元（0.31 百万澳元；0.38 百万澳元），节省了 547（-104；1209）个 BMI 单位和 10.2（-0.19；21.6）个 DALY。这相当于 AUD27311（-1803 美元；58242 美元）的适度成本抵消和每节省一个 DALY 的净成本 AUD29798（占主导地位；0.26 百万澳元）。
BAEW 是负担得起且具有成本效益的，并且在超出资金水平的活动方面产生了可观的附带效益。现在需要确定其成功的基本要素以及与扩大规模相关的任何潜在成本效益。
