This systematic review summarizes the current evidence on the financial return of worksite health promotion programmes aimed at improving nutrition and/or increasing physical activity. Data on study characteristics and results were extracted from 18 studies published up to 14 January 2011. Two reviewers independently assessed the risk of bias of included studies. Three metrics were (re-)calculated per study: the net benefits, benefit cost ratio (BCR) and return on investment (ROI). Metrics were averaged, and a post hoc subgroup analysis was performed to compare financial return estimates between study designs. Four randomized controlled trials (RCTs), 13 non-randomized studies (NRSs) and one modelling study were included. Average financial return estimates in terms of absenteeism benefits (NRS: ROI 325%, BCR 4.25; RCT: ROI -49%, BCR 0.51), medical benefits (NRS: ROI 95%, BCR 1.95; RCT: ROI -112%, BCR -0.12) or both (NRS: ROI 387%, BCR 4.87; RCT: ROI -92%, BCR 0.08) were positive in NRSs, but negative in RCTs. Worksite health promotion programmes aimed at improving nutrition and/or increasing physical activity generate financial savings in terms of reduced absenteeism costs, medical costs or both according to NRSs, whereas they do not according to RCTs. Since these programmes are associated with additional types of benefits, conclusions about their overall profitability cannot be made.
本系统综述总结了目前关于以改善营养和/或增加身体活动为目标的工作场所健康促进计划的财务回报的证据。截至 2011 年 1 月 14 日，从 18 项已发表的研究中提取了研究特征和结果的数据。两名审查员独立评估了纳入研究的偏倚风险。对每一项研究重新计算了三个指标：净收益、效益成本比（BCR）和投资回报率（ROI）。对指标进行了平均化处理，并进行了事后亚组分析，以比较不同研究设计的财务回报估计值。纳入了四项随机对照试验（RCT）、13 项非随机研究（NRS）和一项模型研究。从旷工效益（NRS：ROI 325%，BCR 4.25；RCT：ROI-49%，BCR 0.51）、医疗效益（NRS：ROI 95%，BCR 1.95；RCT：ROI-112%，BCR-0.12）或两者（NRS：ROI 387%，BCR 4.87；RCT：ROI-92%，BCR 0.08）的角度来看，NRS 中的工作场所健康促进计划的财务回报估计值为正，但 RCT 中的财务回报估计值为负。根据 NRS，以改善营养和/或增加身体活动为目标的工作场所健康促进计划可以节省旷工成本、医疗成本或两者的费用，但根据 RCT 却并非如此。由于这些计划与其他类型的收益相关，因此不能得出关于其总体盈利能力的结论。
