Physical activity and exercise appear to improve psychological health. However, the quantitative effects of Tai Chi on psychological well-being have rarely been examined. We systematically reviewed the effects of Tai Chi on stress, anxiety, depression and mood disturbance in eastern and western populations.
Eight English and 3 Chinese databases were searched through March 2009. Randomized controlled trials, non-randomized controlled studies and observational studies reporting at least 1 psychological health outcome were examined. Data were extracted and verified by 2 reviewers. The randomized trials in each subcategory of health outcomes were meta-analyzed using a random-effects model. The quality of each study was assessed.
Forty studies totaling 3817 subjects were identified. Approximately 29 psychological measurements were assessed. Twenty-one of 33 randomized and nonrandomized trials reported that 1 hour to 1 year of regular Tai Chi significantly increased psychological well-being including reduction of stress (effect size [ES], 0.66; 95% confidence interval [CI], 0.23 to 1.09), anxiety (ES, 0.66; 95% CI, 0.29 to 1.03), and depression (ES, 0.56; 95% CI, 0.31 to 0.80), and enhanced mood (ES, 0.45; 95% CI, 0.20 to 0.69) in community-dwelling healthy participants and in patients with chronic conditions. Seven observational studies with relatively large sample sizes reinforced the beneficial association between Tai Chi practice and psychological health.
Tai Chi appears to be associated with improvements in psychological well-being including reduced stress, anxiety, depression and mood disturbance, and increased self-esteem. Definitive conclusions were limited due to variation in designs, comparisons, heterogeneous outcomes and inadequate controls. High-quality, well-controlled, longer randomized trials are needed to better inform clinical decisions.
身体活动和运动似乎可以改善心理健康。然而，太极拳对心理健康的定量影响很少被研究。我们系统地审查了太极拳对东方和西方人群的压力、焦虑、抑郁和情绪障碍的影响。
通过 2009 年 3 月搜索了 8 个英文数据库和 3 个中文数据库。对至少有 1 个心理健康结果的随机对照试验、非随机对照研究和观察性研究进行了检查。由两名评审员提取和验证数据。使用随机效应模型对每个健康结果亚组的随机试验进行荟萃分析。评估了每项研究的质量。
确定了 40 项研究，共计 3817 名受试者。大约评估了 29 项心理测量。在 33 项随机和非随机试验中有 21 项报告，规律的太极拳练习 1 小时至 1 年显著提高了心理健康，包括降低压力（效应量[ES]，0.66；95%置信区间[CI]，0.23 至 1.09）、焦虑（ES，0.66；95%CI，0.29 至 1.03）和抑郁（ES，0.56；95%CI，0.31 至 0.80），以及改善情绪（ES，0.45；95%CI，0.20 至 0.69），在社区居住的健康参与者和患有慢性病的患者中。7 项具有较大样本量的观察性研究强化了太极拳练习与心理健康之间的有益关联。
太极拳似乎与改善心理健康有关，包括降低压力、焦虑、抑郁和情绪障碍，以及提高自尊心。由于设计、比较、异质结果和控制不足的变化，因此得出明确的结论受到限制。需要高质量、良好对照、更长时间的随机试验，以便更好地为临床决策提供信息。
