The Effects of Yoga Interventions on Sleep Quality in Adults People with Depression and Anxiety: A Meta-Analysis of Randomized Controlled Trials

Abstract

Background: Depression is a public health problem affecting older people and causes many health problems. We aim to estimate the effects of yoga interventions on depression, anxiety and sleep quality in adults using meta‐analysis.

Methods: Four digital databases were searched from the inception of databases to March 2022, including Web of Science, Cochrane Library, PubMed and Embase. The Cochrane Collaboration recommendations assessed the publication bias of the included studies. And all test models used a 95% confidence interval (CI).

Results: A total of 10 studies with 582 patients were included in this meta-analysis. The results demonstrated that the depression relief rate of experimental group was better than that of control group ( depression (SMD = -0.20, 95% CI (-0.63 - 0.23) ， p<0.001), anxiety(SMD = -0.55, 95% CI (−1.29 to 0.19 )p<0.001). In addition, there was a significant improvement in sleep quality in the yoga group(SMD=-0.46,95% CI (-0.88,-0.05)p <0.001 ).

Conclusion: This review synthesized current evidence using yoga interventions to reduce negative emotion in adults, especially concerning targeting the applicability between different populations or intervention methods. In addition, yoga interventions are safe and convenient, which have great feasibility and potential to be used as an aspect of psychotherapy for clinical and nursing to improve well-being in adults.
