Tai Chi on psychological well-being: systematic review and meta-analysis

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusions</p> <p>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.</p

Pregnancy outcome of migrant women and integration policy: a systematic review of the international literature

Immigrant mothers in developed countries often experience worse pregnancy outcomes than native women. Several epidemiological studies have described the pregnancy outcome of immigrant women in European receiving countries, with conflicting results. The present systematic review makes a quantitative synthesis of available evidence on the association between pregnancy outcomes and integration policies. We reviewed all epidemiological studies comparing the pregnancy outcome of native versus immigrant women in European countries from 1966 to 2004 and retained 65 for analysis, from 12 host countries. Overall, as compared to native women, immigrant women showed a clear disadvantage for all the outcomes considered: 43% higher risk of low birth weight, 24% of pre-term delivery, 50% of perinatal mortality, and 61% of congenital malformations. The risks were clearly and significantly reduced in countries with a strong integration policy. This trend was maintained even after adjustment for age at delivery and parity. On the basis of an analysis of naturalisation rates, five countries in our sample could be categorised as having a strong policies promoting the integration of immigrant communities. The mechanisms through which integration policies may be protective include the increased participation of immigrant communities in the life of the receiving society, and the decreased stress and discrimination they may face. The results of this study highlight a serious problem of equity in perinatal health across European countries. Immigrant women clearly need targeted attention to improve the health of their newborn, but a deep societal change is also necessary to integrate and respect immigrant communities in receiving societies
