Pdf Summary

The study "Effects of yoga on depressive symptoms, anxiety, sleep quality, and mood in patients with rheumatic diseases" by Pedro de Orleans Casagrande et al. consists of a systematic review and meta-analysis to determine yoga's impact on these mental health variables. Published in 2023, it explores yoga's effectiveness in people with osteoarthritis, fibromyalgia, rheumatoid arthritis, and chronic fatigue syndrome by analyzing 27 studies, 18 of which were used for meta-analysis.<br /><br />The review adheres to PRISMA guidelines and was registered with PROSPERO. Literature searches were conducted across several databases until March 2022. Key findings include:<br /><br />1. **Depressive Symptoms**: Yoga significantly reduced depressive symptoms across eight randomized controlled trials (RCTs) when compared to control groups, showing a large effect size (SMD: -0.88). However, when compared to other forms of exercise, the effect was not significant.<br /><br />2. **Anxiety**: Moderate reductions in anxiety were observed in five RCTs favoring yoga against control groups (SMD: -0.51).<br /><br />3. **Sleep Quality**: Three RCTs demonstrated a large positive impact of yoga on sleep quality compared to controls (SMD: -0.96).<br /><br />4. **Mood**: Although yoga indicated potential benefits, insufficient studies with appropriate designs precluded a meta-analysis on mood outcomes.<br /><br />The majority of studies were noted to have a high or uncertain risk of bias, primarily due to sample losses, lack of detailed intervention protocols, and the absence of intention-to-treat analysis. Styles of yoga employed included Hatha, isometric, and chair yoga, with varying session lengths and frequencies.<br /><br />Overall, the study concludes that yoga can effectively improve depression, anxiety, and sleep quality in patients with rheumatic diseases but emphasizes the need for more well-conducted RCTs comparing yoga against other forms of exercises to validate these results comprehensively.
