This study was to examine the effects of adherence to a 6-month t'ai chi exercise program on glucose control, diabetic self-care activities, and quality of life among individuals with type 2 diabetes.
The data from a quasi-experimental study at multisite health-promotion centers in Korea with pretest and 3- and 6-month post-test measures were used. Ninety-nine (99) adults diagnosed with type 2 diabetes and HbA1c 6.0 or higher were included in the analysis. The t'ai chi intervention consisted of 19 movements from Yang and Sun styles provided twice a week for 6 months. Sixty-two (62) subjects completed both pretest and post-test measures. To achieve the desired outcomes, subjects needed to complete 80% of the sessions of the t'ai chi program, and 31 subjects who met this criteria were compared to those who did not (n = 31). Outcome measures included glucose control (fasting blood sugar, HbA1c), diabetic self-care activities, and quality of life (36-Item Short Form Health Survey, version 2).
Using repeated measure analysis of variance for baseline, 3 months, and 6 months, the adherent group had greater decline in fasting glucose (interaction effect F = 5.60, df = 2, p < 0.05) and HbA1c (interaction effect F = 4.15, df = 2, p < 0.05) than the nonadherers. The adherent group performed significantly more diabetic self-care activities (interaction effect F = 5.13, df = 2, p < 0.05), and had better quality of life in mental component summary, social functioning, mental health, and vitality as compared to the nonadherent group. The significant differences in quality of life remained after adjusting for self-care activities except for mental health, which was no longer significant.
For those with type 2 diabetes, t'ai chi could be an alternative exercise intervention to increase glucose control, diabetic self-care activities, and quality of life. Whether t'ai chi can reduce or prevent diabetic complications requires further study.
本研究旨在探讨坚持为期6个月的太极拳锻炼计划对2型糖尿病患者血糖控制、糖尿病自我护理活动及生活质量的影响。
采用韩国多站点健康促进中心的一项准实验研究数据，该研究有前测以及3个月和6个月后的后测。分析纳入了99名被诊断为2型糖尿病且糖化血红蛋白（HbA1c）为6.0或更高的成年人。太极拳干预包括杨氏和孙氏风格的19个动作，每周进行两次，共6个月。62名受试者完成了前测和后测。为达到预期结果，受试者需完成太极拳计划80%的课程，将31名符合此标准的受试者与未符合标准的受试者（n = 31）进行比较。结果指标包括血糖控制（空腹血糖、HbA1c）、糖尿病自我护理活动及生活质量（36项简短健康调查量表，第2版）。
使用重复测量方差分析对基线、3个月和6个月的数据进行分析，坚持锻炼组的空腹血糖下降幅度（交互效应F = 5.60，自由度df = 2，p < 0.05）和HbA1c下降幅度（交互效应F = 4.15，自由度df = 2，p < 0.05）均大于未坚持锻炼组。坚持锻炼组进行的糖尿病自我护理活动显著更多（交互效应F = 5.13，自由度df = 2，p < 0.05），并且与未坚持锻炼组相比，在心理综合评分、社会功能、心理健康和活力方面的生活质量更好。除心理健康不再显著外，在调整自我护理活动后，生活质量的显著差异仍然存在。
对于2型糖尿病患者，太极拳可能是一种可增加血糖控制、糖尿病自我护理活动及生活质量的替代运动干预方式。太极拳是否能减少或预防糖尿病并发症还需要进一步研究。
