The purpose of this systematic review is to analyze current lifestyle intervention literature conducted in U.S. rural areas to identify the most effective and impactful interventions on physical activity outcomes. Quality of studies was assessed using the Cochrane Collaboration's risk of bias tool. Exploratory calculations of effect size and 95% confidence intervals were performed to demonstrate trends in clinical importance. Eight trials which included 1,399 adult participants met the inclusion criteria for review. Two trials reported a significant difference in the increase of physical activity between groups with medium to large effect sizes. Interventions which are very personalized or tailored and/or include many intervention contacts appear to be most effective. However, the small number of studies, mixed findings, and the risk of bias limit our ability to draw conclusion.
本系统评价的目的是分析美国农村地区目前开展的生活方式干预文献，以确定对身体活动结果最有效和最具影响力的干预措施。使用Cochrane协作网的偏倚风险工具评估研究质量。进行了效应大小和95%置信区间的探索性计算，以证明临床重要性的趋势。八项试验纳入了1399名成年参与者，符合纳入综述的标准。两项试验报告称，组间身体活动增加存在显著差异，效应大小为中到大型。非常个性化或量身定制的干预措施和/或包含多次干预接触的措施似乎最有效。然而，研究数量少、结果不一以及偏倚风险限制了我们得出结论的能力。
