痛苦是一个日益严重的公共健康问题。我们的目的是调查艾扬格瑜伽项目对痛苦女性感知压力和心理结果的影响，并评估潜在的剂量效应关系。72名女性痛苦受试者被纳入一项三臂随机对照试验，并被分配到瑜伽1组（n = 24），在3个月内进行12次90分钟的练习，瑜伽2组（n = 24），在3个月内进行24次练习，或等待名单对照组（n = 24）。主要结果为压力感知，采用Cohen压力量表测量；次要结局包括状态特质焦虑、抑郁、心理和身体生活质量（QOL）、情绪状态概况、幸福感和身体不适。三个月后，与对照组相比，瑜伽组的女性在感知压力（P = 0.003）、状态特征焦虑（P = 0.021和P = 0.003）、抑郁（P = 0.008）、心理生活质量（P = 0.012）、情绪状态（P = 0.007）和身体不适（P = 0.012）方面都有显著改善。两种瑜伽项目对这些结果的效果相似；然而，练习次数较少的一组（瑜伽第一组）的依从性更好。剂量效应仅在背痛、焦虑和抑郁的组独立效应分析中可见。这些发现表明，艾扬格瑜伽有效地减少了痛苦，并改善了相关的心理和生理结果。此外，每周上两次瑜伽课并不比每周上一次瑜伽课优越，因为每周上两次瑜伽课的人依从性有限。
Distress is an increasing public health problem. We aimed to investigate the effects of an Iyengar yoga program on perceived stress and psychological outcomes in distressed women and evaluated a potential dose-effect relationship. Seventy-two female distressed subjects were included into a 3-armed randomized controlled trial and allocated to yoga group 1 (n = 24) with twelve 90 min sessions over 3 months, yoga group 2 (n = 24) with 24 sessions over 3 months, or a waiting list control group (n = 24). The primary outcome was stress perception, measured by Cohen Stress Scale; secondary outcomes included state trait anxiety, depression, psychological and physical quality of life (QOL), profile of Mood States, well being, and bodily complaints. After three months, women in the yoga groups showed significant improvements in perceived stress (P = 0.003), state trait anxiety (P = 0.021 and P = 0.003), depression (P = 0.008), psychological QOL (P = 0.012), mood states being (P = 0.007), and bodily complaints well(P = 0.012) when compared to controls. Both yoga programs were similarly effective for these outcomes; however, compliance was better in the group with fewer sessions (yoga group 1). Dose effects were seen only in the analysis of group-independent effects for back pain, anxiety, and depression. These findings suggest that Iyengar yoga effectively reduces distress and improves related psychological and physical outcomes. Furthermore, attending twice-weekly yoga classes was not superior to once-weekly classes, as a result of limited compliance in the twice-weekly group.
