Walking is a good way to meet physical activity guidelines. We examined the effectiveness of walking in groups compared with walking alone or inactive controls in physically healthy adults on physical activity and quality of life. (PROSPERO CRD42016033752).
We searched Medline, Embase, Cinahl, Web of Knowledge Science Citation Index, and Cochrane CENTRAL until March 2016, for any comparative studies, in physically healthy adults, of walking in groups compared with inactive controls or walking alone, reporting any measure of physical activity. We searched references from recent relevant systematic reviews. Two reviewers checked study eligibility and independently extracted data. Disagreements were resolved through discussion. Quality was assessed using likelihood of selection, performance, attrition, and detection biases. Meta-analysis was conducted using Review Manager 5.3.
From 1,404 citations, 18 studies were included in qualitative synthesis and 10 in meta-analyses. Fourteen compared group walking to inactive controls and four to walking alone. Eight reported more than one measure of physical activity, none reported according to current guidelines. Group walking compared with inactive controls increased follow-up physical activity (9 randomized controlled trials, standardized mean difference [SMD] 0.58 [95 percent confidence interval {CI}, 0.34-0.82] to SMD 0.43 [95 percent CI, 0.20-0.66]). Compared with walking alone, studies were too few and too heterogeneous to conduct meta-analysis, but the trend was improved physical activity at follow-up for group walking participants. Seven (all inactive control) reported quality-of-life: five showed statistically significantly improved scores.
Better evidence may encourage government policy to promote walking in groups. Standardized physical activity outcomes need to be reported in research.
散步是满足身体活动指南的一种好方法。我们考察了与单独散步或不活动对照相比，群体散步对身体健全的成年人的身体活动和生活质量的影响。（PROSPERO CRD42016033752）。
我们检索了 Medline、Embase、Cinahl、Web of Knowledge 科学引文索引和 Cochrane 中心，截至 2016 年 3 月，检索了任何关于群体散步与不活动对照或单独散步比较的身体健全成年人的比较研究，报告了任何身体活动测量指标。我们检索了近期相关系统评价的参考文献。两名审查员检查了研究的纳入标准，并独立提取了数据。意见分歧通过讨论解决。使用选择、表现、失访和检测偏倚的可能性来评估质量。使用 Review Manager 5.3 进行荟萃分析。
从 1404 条引文，18 项研究被纳入定性综合分析，10 项研究被纳入荟萃分析。其中 14 项研究将群体散步与不活动对照进行了比较，4 项研究将群体散步与单独散步进行了比较。有 8 项研究报告了不止一项身体活动测量指标，但没有一项研究是根据当前指南报告的。与不活动对照相比，群体散步增加了随访期间的身体活动（9 项随机对照试验，标准化均数差[SMD]为 0.58[95%置信区间{CI}，0.34-0.82]至 SMD 0.43[95%CI，0.20-0.66]）。与单独散步相比，研究数量太少且异质性太大，无法进行荟萃分析，但群体散步参与者的随访身体活动有改善趋势。有 7 项（均为不活动对照）报告了生活质量：其中 5 项显示出统计学上显著改善的评分。
更好的证据可能会鼓励政府政策来促进群体散步。研究需要报告标准化的身体活动结果。
