A culturally tailored lifestyle intervention combining moderate caloric restriction and aerobic exercise significantly improves glycemic control (HbA1c) and reduces blood pressure in older African-American adults with type 2 diabetes, independent of the modest magnitude of weight loss achieved.
For older African-American adults with type 2 diabetes, a structured program that respects cultural food preferences and provides a safe, supervised environment for moderate aerobic exercise can significantly improve blood sugar control and blood pressure, even if the amount of weight lost is small. The key is consistent behavioral support and safe physical activity, not just drastic dieting.
The intervention program was effective in improving glycemic and blood pressure control. The decrease in HbA1c values was generally independent of the relatively modest changes in dietary intake, weight, and activity and may reflect indirect program effects on other aspects of self-care.
Why this rating
Randomized Controlled Trial design, though limited by a small sample size (n=64) and early termination due to funding constraints.
