Dietary Weight Loss Program with the Addition of Tai Chi More Beneficial to Obese Older Women
March 27, 2013 - This ancillary study of a randomized
clinical trial, carried out at University of Rhode Island, was to examine the
additive effect of Tai Chi to diet education on the traditional coronary heart
disease (CHD) risk factor low-density lipoprotein cholesterol (LDL-C) and on
emerging CHD risk factors in older obese women.
Participants: 26 obese women (with ages ranging from 55
to 67; mean body mass index, 34.3<>4.0 kg/m2) were enrolled and randomly
assigned to the diet education group or the diet education plus Tai Chi group.
Intervention:nutes of diet
education per week. The diet education plus Tai Chi group also received 45
minutes of Tai Chi three times per week for 16 weeks.
Anthropometrics (height, weight, BMI, waist circumference, and hip
circumference), clinical variables (blood pressure), and biochemical variables
(standard lipid profile, apolipoprotein B, LDL particle size) were measured. The
primary outcome was LDL-C, and the secondary outcomes were apolipoprotein B and
LDL particle size.
Results: Neither LDL-C nor apolipoprotein B improved in
either group. Percentage of large LDL particles after the intervention was
increased in the diet education plus Tai Chi group compared with the diet
education group. Weight, waist circumference, and high-density lipoprotein
cholesterol decreased in both groups from baseline to post-intervention.
Triacylglycerol and dietary screening tool scores increased in both groups.
Additional improvements were seen in the diet education plus Tai Chi group,
including a significant increase in Dietary Approaches to Stop Hypertension
score from baseline to post-intervention.
Conclusion: The addition of Tai Chi to
diet education is more effective than diet education alone at improving diet
quality and emerging CHD risk factors, such as LDL particle size, in obese older
