This systematic review and meta-analysis aimed to determine the effectiveness of yoga on anthropometry, quality of life, and lipid profiles in patients with obesity and central obesity.
The Cochrane Central Register of Controlled Trials (CENTRAL) and PubMed (1985-January 2022) and trial registries for relevant randomised clinical trials were used. Relevant and published randomised clinical trials were reviewed and evaluated. The primary outcomes were anthropometry measurements, which were weight, waist circumference, body mass index (BMI), and body fat percentages. The secondary outcomes were changes in quality of life, psychological impact, lipid profile measurement, presence of adverse events, and changes in blood pressure and blood glucose. We assessed the data for risk of bias, heterogeneity, sensitivity, reporting bias, and quality of evidence.
15 studies are included, involving 1161 participants. The analysis performed is based on three comparisons. For the first comparison between yoga and control, yoga reduces the waist circumference (MD -0.84, 95% CI [-5.12 to 3.44]), while there is no difference in body weight, BMI, or body fat percentages. In the second comparison between yoga and calorie restriction, yoga reduces body weight (MD -3.47, 95% CI [-6.20 to -0.74]), while there is no difference in waist circumference, BMI, or body fat percentage. In the third comparison between yoga and exercise, yoga reduces the body weight (MD -7.58, 95% CI [-11.51 to -3.65]), while there is no difference in waist circumference or BMI. For the secondary outcomes, yoga intervention reduces total cholesterol (MD -17.12, 95% CI [-32.24 to -2.00]) and triglycerides (MD -21.75, 95% CI [-38.77 to -4.73]) compared to the control group, but there is no difference compared to the calorie restriction and exercise group. There is no difference in the rest of the outcomes, which are LDL, HDL, quality of life, psychological impact, adverse events, blood pressure, and blood glucose. However, findings are not robust due to a high risk of bias and low-quality evidence.
From our review, there were methodological drawbacks and very low to moderate quality of evidence across all comparisons, and hence, it is inconclusive to say that yoga can significantly improve anthropometric parameters. More well-designed trials are needed to confirm and support the beneficial effects of yoga.
本系统评价和荟萃分析旨在确定瑜伽对肥胖和中心性肥胖患者的人体测量学、生活质量和血脂谱的有效性。
使用 Cochrane 中央对照试验注册库（CENTRAL）和 PubMed（1985 年 1 月至 2022 年 1 月）以及相关随机临床试验的试验注册处。审查和评估了相关和已发表的随机临床试验。主要结局指标是体重、腰围、体重指数（BMI）和体脂百分比等人体测量学测量值。次要结局指标为生活质量变化、心理影响、血脂谱测量、不良事件发生情况以及血压和血糖变化。我们评估了数据的偏倚风险、异质性、敏感性、报告偏倚和证据质量。
纳入了 15 项研究，涉及 1161 名参与者。进行的分析基于三项比较。第一项比较是瑜伽与对照组相比，瑜伽可降低腰围（MD -0.84，95%CI [-5.12 至 3.44]），而体重、BMI 或体脂百分比没有差异。第二项比较是瑜伽与热量限制相比，瑜伽可降低体重（MD -3.47，95%CI [-6.20 至 -0.74]），而腰围、BMI 或体脂百分比没有差异。第三项比较是瑜伽与运动相比，瑜伽可降低体重（MD -7.58，95%CI [-11.51 至 -3.65]），而腰围或 BMI 没有差异。对于次要结局，与对照组相比，瑜伽干预可降低总胆固醇（MD -17.12，95%CI [-32.24 至 -2.00]）和甘油三酯（MD -21.75，95%CI [-38.77 至 -4.73]），但与热量限制和运动组相比无差异。其余结局，包括 LDL、HDL、生活质量、心理影响、不良事件、血压和血糖，无差异。然而，由于所有比较的偏倚风险高和证据质量低等原因，结果并不稳健，因此，瑜伽是否能显著改善人体测量参数尚无定论。需要更多设计良好的试验来证实和支持瑜伽的有益效果。
