To clarify the effect of programmed exercise (PE), performed for at least six weeks, on perceived stress (PS) in middle aged and old women.
A structured search was carried out in PubMed, Embase, Cochrane Library, Scielo, Web of Science and Scopus, from database inception through January 10, 2018, without language restriction. The US, UK, and Australian clinical trials databases were also searched. The search included a combination of the terms "programmed exercise", "perceived stress", "menopausal women" and "randomized controlled trial" (RCTs). PE was classified according to duration as "mid-term exercise intervention" (MTEI; mean duration 6 months), and "long-term exercise intervention" (LTEI; mean duration 12 months). Mean ± standard deviations of changes in PS scores, as assessed with different questionnaires, were calculated as standardized mean differences (SMDs) and used as effect size for meta-analysis. SMDs of PS after intervention were pooled using a random-effects model. Study quality and bias risk were assessed with the Cochrane tool.
Five RCTs that studied midlife and older women (mean age 47.0 ± 1.7 years minimum to 71.8 ± 5.6 maximum) were included in the meta-analysis. There was no significant effect of PE on PS score (SMD: -0.16; 95% CI: -0.43 to 0.11). In subgroup analyses, there was no significant effect of PE on PS with mid-term interventions (SMD: - 0.17; 95% CI: -0.59 to 0.25) nor with long-term interventions (SMD: -0.02; 95% CI: -0.42 to 0.38) as compared with controls.
PE of low to moderate intensity does not improve PS in midlife and older women.
明确至少持续 6 周的有计划锻炼（PE）对中年和老年女性感知压力（PS）的影响。
系统检索了 PubMed、Embase、Cochrane 图书馆、Scielo、Web of Science 和 Scopus 数据库，检索时间为建库至 2018 年 1 月 10 日，未设语言限制。还检索了美国、英国和澳大利亚临床试验数据库。检索词包括“programmed exercise”“perceived stress”“menopausal women”和“randomized controlled trial”。根据持续时间，PE 被分类为“中期运动干预”（MTEI；平均持续时间 6 个月）和“长期运动干预”（LTEI；平均持续时间 12 个月）。采用不同问卷评估 PS 评分变化的均值±标准差，计算标准化均数差（SMD）作为 meta 分析的效应量。采用随机效应模型汇总干预后 PS 的 SMD。采用 Cochrane 工具评估研究质量和偏倚风险。
纳入了 5 项 RCT 研究，共纳入中年和老年女性（平均年龄 47.0±1.7 岁，最小至 71.8±5.6 岁）。PE 对 PS 评分无显著影响（SMD：-0.16；95%CI：-0.43 至 0.11）。亚组分析显示，中期干预（SMD：-0.17；95%CI：-0.59 至 0.25）和长期干预（SMD：-0.02；95%CI：-0.42 至 0.38）对 PS 均无显著影响。
低到中等强度的 PE 并不能改善中年和老年女性的 PS。
