title: The effect of weight loss on change in waist-to-hip ratio in patients with type II diabetes.
abstract: This study sought to determine whether weight loss would alter body fat distribution in obese men and women with type II diabetes. Subjects were 60 women and 33 men who participated in a year-long weight loss program. Weight losses of women and men, respectively, averaged 13.4 kg and 16.8 kg at six months and 11.2 kg and 13.1 kg at one year. WHR decreased significantly in both genders: for women, WHR decreased from 0.95 at baseline to 0.93 at six months and 0.94 at one year; for men WHR decreased from 0.99 at baseline to 0.96 at six months and 0.96 at one year. Subjects with greater upper body obesity at baseline did not lose more weight than subjects with less upper body obesity, but they did have greater reductions in WHR at six months in both genders and at one year in men. The magnitude of WHR reduction was strongly related to the amount of weight lost in men, but was not related to weight loss in women. Improvements in fasting glucose, fasting insulin, and HbA1 were significantly related to weight loss, but not to reductions in WHR. Thus, participation in a weight loss program had beneficial effects on body fat distribution in patients with type II diabetes, but these changes in WHR were not independently associated with improvements in glycemic control.
