Impact of a Program of Tai Chi Plus Behaviorally Based Dietary Weight Loss on Physical Functioning and Coronary Heart Disease Risk Factors: A Community-Based Study in Obese Older Women
Date of Original Version
This study employed a quasi-experimental design in a community-based study translating the results of our recent findings on the combined effects of Tai Chi and weight loss on physical function and coronary heart disease (CHD) risk factors. A 16-week intervention was conducted to assess the impact of Tai Chi plus a behavioral weight loss program (TCWL, n = 29) on obese (body mass index [BMI] = 35.4 ± 0.8 kg/m2) older (68.2 ± 1.5 yr.) women compared to a control group (CON, n = 9, BMI = 38.0 ± 1.5 kg/m2, 65.6 ± 2.7 yr.), which was asked to maintain their normal lifestyle. The TCWL group lost weight (1.6 ± 2.9 kg, P = 0.006) while the CON group did not (1.2 ± 1.9 kg, P = 0.106). Physical functioning as measured by the short physical performance battery improved in TCWL when compared to the CON group (β = 1.94, 95% Confidence Interval [CI]: 1.12, 2.76, P < 0.001). TCWL also improved in sit-and-reach flexibility (β = −2.27, 95% CI: −4.09, −0.46, P = 0.016), body fat mass (BMI, β = −0.65, 95% CI: −1.03, −0.26, P = 0.002), waist circumference (β = −1.78, 95% CI: −2.83, −0.72, P = 0.002), systolic blood pressure (β = −16.41, 95% CI: −21.35, −11.48, P < 0.001), and diastolic blood pressure (β = −9.52, 95% CI: −12.65, −6.39, P < 0.001). Thus, TCWL intervention may represent an effective strategy to improve physical function and ameliorate CHD risk in the older adult population.
