这项荟萃分析总结了旨在增加健康成年人身体活动的干预措施的效果。综合检索找到了358份符合纳入条件的报告。随机效应分析用于综合数据。潜在的调节变量进行了检查与荟萃分析类似的方差分析和回归。研究了调节变量的稳健性和发表偏倚。荟萃分析结果来自包括99，011名受试者的研究。治疗组与对照组比较的总体平均效应量（d）为0.19（治疗组受试者的平均值高于对照组受试者）。这0.19与治疗和对照受试者之间496步/天的平均差异一致。探索性主持人分析表明，最有效的干预措施的特点包括行为干预而不是认知干预，面对面的交付与中介干预（例如，通过电话，邮件等），目标是个人而不是社区参与者的特征与体力活动效应大小无关。大量的研究间异质性仍然超出了个别主持人。这些发现表明，旨在增加活动的干预措施是适度有效的。研究结果表明，干预措施应强调行为策略，而不是认知策略，以增加体力活动。
This meta-analysis summarized effects of interventions designed to increase physical activity among healthy adults. Comprehensive searching located 358 reports eligible for inclusion. Random-effects analyses were used to synthesize data. Potential moderator variables were examined with meta-analytic analogues of ANOVA and regression. Moderator variable robustness and publication bias were explored. Meta-analytic results were computed from studies including 99,011 subjects. The overall mean effect size (d) for treatment vs. control groups comparisons was 0.19 (higher mean for treatment than control subjects). This 0.19 is consistent with a mean difference of 496 steps/day between treatment and control subjects. Exploratory moderator analyses suggested that the characteristics of the most effective interventions included behavioral interventions instead of cognitive interventions, face-to-face delivery versus mediated interventions (e.g. via telephone, mail, etc.), and targeted individuals instead of communities. Participant characteristics were unrelated to physical activity effect sizes. Substantial between-studies heterogeneity remained beyond individual moderators. These findings suggest that interventions designed to increase activity are modestly effective. Findings suggest interventions should emphasize behavioral strategies over cognitive strategies to increase physical activity.
