Qigong for mental health and sleep quality in postmenopausal women: A randomized controlled trial

BACKGROUND: Menopause is one of the stages in a woman's life that affects her psychological health, the most frequent being anxiety and depression. In addition, another problem related to this stage is the lack of sleep that causes a decrease in the quality of sleep. The purpose of this randomized controlled trial was to analyze the effectiveness of a Qigong exercise program on sleep quality, anxiety, and depression in Spanish postmenopausal women. METHODS: A total of 125 women were randomly assigned to an experimental group (EG) (n = 63) that carried out a Qigong exercise program for 12 weeks, or a control group (CG) (n = 62), which did not perform any type of intervention. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). RESULTS: Women who underwent an intervention program experienced significant improvements for all measured variables, except for the use of sleeping medication and daytime dysfunctions that did not show any significant effect with respect to the group and group × time interaction. CONCLUSIONS: After an intervention based on a BaDuanJin Qigong exercise program for 12 weeks, improvements were observed in sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, the total score of the PSQI, anxiety and depression in postmenopausal Spanish women.
