To synthesise and critically appraise the quality of existing evidence about the effects of yoga on physical and psychological outcomes among older adults.
A systematic review and meta-analysis.
Participants aged 60 and above.
Nine English and two Chinese electronic bibliographic databases, including MEDLINE OvidSP, PsycINFO, AMED, EMBASE, Global Health, PubMed, Scopus, CINAHL, Cochrane Library, Hyread and WanFang databases, were searched. Randomised controlled trials (RCT) of yoga on physical and psychological outcomes among older adults were included. Meta-analysis was conducted for outcomes studied in three or more studies, otherwise narrative synthesis was performed.
Fifteen studies were included for review. The results of meta-analysis after sensitivity analysis showed that yoga significantly improved balance (SMD = 0.81, 95% CI: 0.48-1.14, p < .001, II = 59%), flexibility (SMD = 0.38, 95% CI: 0.07-0.68, p = .020, II 34%), muscle strength (SMD = 0.49, 95% CI: 0.18-0.79, p = .002, I 43%) and depressive symptoms (SMD = 0.50, 95% CI = 0.09-0.91, p = .01, I 0%). There was insufficient data for meta-analysis on gait and other psychological outcomes. Narrative synthesis suggested that yoga has positive effects on reducing anxiety, but its effects on improving gait and reducing stress among older adults were inconclusive.
The results of this review supported the beneficial effects of yoga on physical outcomes among older adults, but the heterogeneity across studies was relatively high. Evidence related to the effect on psychological outcomes was limited.
综合并批判性评价现有关于瑜伽对老年人身体和心理结果影响的证据质量。
系统评价和荟萃分析。
年龄在 60 岁及以上的参与者。
检索了 9 个英文和 2 个中文电子文献数据库，包括 MEDLINE OvidSP、PsycINFO、AMED、EMBASE、全球健康、PubMed、Scopus、CINAHL、Cochrane 图书馆、Hyread 和万方数据库。纳入了关于瑜伽对老年人身体和心理结果影响的随机对照试验（RCT）。对研究了三个或更多研究结果的进行荟萃分析，否则进行叙述性综合。
共纳入 15 项研究进行综述。经过敏感性分析后的荟萃分析结果表明，瑜伽显著改善了平衡（SMD=0.81，95%CI：0.48-1.14，p<0.001，II=59%）、柔韧性（SMD=0.38，95%CI：0.07-0.68，p=0.020，II=34%）、肌肉力量（SMD=0.49，95%CI：0.18-0.79，p=0.002，I=43%）和抑郁症状（SMD=0.50，95%CI=0.09-0.91，p=0.01，I=0%）。但对于步态和其他心理结果，没有足够的数据进行荟萃分析。叙述性综合表明，瑜伽对减轻焦虑有积极影响，但对改善老年人步态和减轻压力的效果尚不确定。
本综述结果支持瑜伽对老年人身体结果的有益影响，但研究之间的异质性相对较高。与心理结果相关的证据有限。
