摘要
Background:Sleep disorders are common in older adults and have a negative influence on their physical and mental health.General aerobic exercises(GAEs)have long been used in the treatment of sleep disorders as a non-pharmacological measure.However,there is no consensus on the efficacy of traditional Chinese exercises(TCEs)for treating sleep disorders in older adults and the difference between TCEs and GAEs.Objective:This study assessed the effects of TCEs and GAEs on the sleep quality of older adults and the differences between these two interventions.Search strategy:Pub Med,Embase,Cochrane Library,Web of Science,China Biology Medicine disc,China National Knowledge Infrastructure,China Science Journal Database and Wanfang Data were searched from their inception to August 2020.Inclusion criteria:Randomized controlled trials(RCTs)that evaluated the effects of TCEs and GAEs on older adults with sleep disorders were included.Data extraction and analysis:Data were extracted by two researchers working independently.The risk bias of included studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0 and the quality of evidence was assessed using the Grades of Recommendation,Assessment,Development and Evaluation approach.The Pittsburgh Sleep Quality Index(PSQI)was used to estimate sleep quality.Meta-analyses were performed to assess the total PSQI score of the exercise intervention as the primary outcome,and the scores of subjective sleep quality,sleep latency,sleep duration,habitual sleep efficiency,sleep disturbance,use of sleep medication and daytime dysfunction were assessed as secondary outcomes.Subgroup,sensitivity,and meta-regression analyses were conducted to assess the contribution of covariables to heterogeneity.Results:A total of 22 RCTs(including 1747 participants)were included in the meta-analysis.The results indicated that TCEs(weighted mean difference[WMD]=-2.14,95%confidence interval[CI][-2.82,-1.46],P<0.001;heterogeneity:P<0.001,I2=82%;15 studies,n=1063)and GAEs(WMD=-2
