Effectiveness of a behavioral weight control program for blacks and whites with NIDDM.

Author information

  • 1University of Pittsburgh, Pennsylvania, USA.



To compare the weight losses of black and white patients with NIDDM treated in a year-long behavioral weight loss program.


Subjects were randomly assigned to a behavioral program that either used a low-calorie diet throughout or included two 12-week periods of a very-low calorie diet (VLCD). Weight, dietary intake, and exercise were measured at 0, 6, and 12 months of treatment, and attendance and self-monitoring records were assessed weekly throughout the year.


Blacks had smaller weight losses than whites regardless of treatment condition. Overall weight losses (baseline to 1 year) were 7.1 kg in blacks vs 13.9 kg in whites. The differences in overall outcome resulted primarily from greater weight regain in blacks during months 6-12 than in whites. There was a trend for blacks to have poorer attendance than whites during the latter half of the program and for blacks to report smaller changes in calorie intake from baseline to 6 months.


The results confirm prior studies with nondiabetic patients showing smaller weight losses in blacks than in whites and suggest that these differences may result primarily from faster weight regain in blacks. Further research is needed to more carefully examine the variables that may explain this difference and to develop more effective programs for blacks with NIDDM.
