目的评估针对久坐不动的非裔美国女性的生活方式体育活动项目增加体育活动和保持体重的边际成本。结果包括每周总中高强度体力活动分钟数、休闲时间中高强度体力活动和步行分钟数的变化，以及基线和维持48周时体重稳定性的变化。计算每个结局的边际成本-效果比（MCERs），并使用bootstrap方法计算95%置信区间（ci）。该分析是从社会角度进行的，并以2013年的美元计算。结果260名参与者的项目成本为165±19美元，参与者成本为164±35美元，总成本为329±49美元。步行变化的MCER为1.50美元/分钟/周（95% CI 1.28-1.87），中度至剧烈体力活动的MCER为1.73美元/分钟/周（95% CI 1.41-2.18），休闲时间中度至剧烈体力活动的MCER为1.94美元/分钟/周（95% CI 1.58-2.40）。基于加速度计的步数mcr为每步0.46美元（95% CI 0.30-0.85），体重稳定性为412美元（95% CI 399-456）。结论妇女生活方式体力活动计划是一种相对低成本的增加体力活动的策略。增加体力活动的边际成本低于保持体重稳定的边际成本。参与者在项目中与时间相关的成本几乎占总成本的一半，这表明从业者和政策制定者在将生活方式体育活动项目推广到实践中时应该考虑参与者的成本。
Objective To evaluate the marginal costs of increasing physical activity and maintaining weight for a lifestyle physical activity program targeting sedentary African American women. Methods Outcomes included change in minutes of total moderate to vigorous physical activity, leisure-time moderate to vigorous physical activity and walking per week, and weight stability between baseline and maintenance at 48 weeks. Marginal cost-effectiveness ratios (MCERs) were calculated for each outcome, and 95% confidence intervals (CIs) were computed using a bootstrap method. The analysis was carried out from the societal perspective and calculated in 2013 US dollars. Results For the 260 participants in the analysis, program costs were $165±$19, and participant costs were $164±$35, for a total cost of $329±$49. The MCER for change in walking was $1.50/min/wk (95% CI 1.28–1.87), for change in moderate to vigorous physical activity was $1.73/min/wk (95% CI 1.41–2.18), and for leisure-time moderate to vigorous physical activity was $1.94/min/wk (95% CI 1.58–2.40). The MCER for steps based on the accelerometer was $0.46 per step (95% CI 0.30-0.85) and weight stability was $412 (95% CI 399–456). Conclusions The Women’s Lifestyle Physical Activity Program is a relatively low-cost strategy for increasing physical activity. The marginal cost of increasing physical activity is lower than for weight stability. The participant costs related to time in the program were nearly half the total costs, suggesting that practitioners and policymakers should consider the participant cost when disseminating a lifestyle physical activity program into practice.
