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

Area of Science:

• Obesity research
• Diabetes management
• Behavioral science

Background:

• Non-insulin-dependent diabetes mellitus (NIDDM) is a growing public health concern.
• Effective weight management is crucial for NIDDM patients.
• Disparities in weight loss outcomes between racial groups warrant investigation.

Purpose of the Study:

• To compare weight loss between black and white patients with NIDDM in a behavioral weight loss program.
• To identify potential factors contributing to observed differences in weight loss outcomes.

Main Methods:

• Randomized assignment to behavioral weight loss programs with varying dietary interventions (low-calorie diet vs. very-low calorie diet periods).
• Measurements included weight, dietary intake, and exercise at baseline, 6 months, and 12 months.
• Weekly assessments of attendance and self-monitoring records.

Main Results:

• Black patients achieved significantly less weight loss compared to white patients (7.1 kg vs. 13.9 kg overall).
• Greater weight regain was observed in black patients during months 6-12.
• Trends suggested poorer attendance and smaller reported dietary intake changes in black patients.

Conclusions:

• Findings align with previous studies showing lower weight loss in black individuals.
• Faster weight regain in black patients may explain the observed disparities.
• Further research is needed to understand and address factors contributing to these differences for improved NIDDM management in black populations.
