To investigate the possible role of physical activity (PA) on sleep disturbance in breast cancer patients.
Literature in PubMed, Embase, and the Cochrane Library was systematically searched until January 30, 2020. Randomized controlled trials that focused on the role of PA interventions on sleep disturbance were selected. The main outcome measures included the global Pittsburgh Sleep Quality Index (PSQI) score and PSQI subscales. Subgroup analysis was performed based on the study area and intervention time. The stability and authenticity of the results were measured by sensitivity analysis and publication bias analysis, respectively.
Six articles were included in this meta-analysis. There were no significant differences in global PSQI scores between the PA intervention group and the usual care group (P = 0.057). As for PSQI subscales, PA intervention could improve sleep quality (weighted mean difference = 0.22; 95% confidence interval 0.04-0.40; P = 0.018). There were no significant differences in sleep duration, sleep medication, sleep latency, habitual sleep efficiency, and daytime dysfunction between the two groups (all P > 0.05).
PA serves as an effective intervention to improve sleep quality.
探讨身体活动（PA）对乳腺癌患者睡眠障碍的可能作用。
系统检索了 PubMed、Embase 和 Cochrane 图书馆截至 2020 年 1 月 30 日的文献。选择了专注于 PA 干预对睡眠障碍作用的随机对照试验。主要结局指标包括匹兹堡睡眠质量指数（PSQI）总分和 PSQI 各分量表。根据研究区域和干预时间进行了亚组分析。分别通过敏感性分析和发表偏倚分析来测量结果的稳定性和真实性。
共有 6 篇文章纳入本荟萃分析。PA 干预组与常规护理组的 PSQI 总分无显著差异（P=0.057）。在 PSQI 各分量表方面，PA 干预可改善睡眠质量（加权均数差=0.22；95%置信区间 0.04-0.40；P=0.018）。两组的睡眠时间、睡眠药物、睡眠潜伏期、习惯性睡眠效率和日间功能障碍无显著差异（均 P＞0.05）。
PA 是改善睡眠质量的有效干预措施。
