Race, hormones and diabetes risk

Natriuretic peptides (NP) are hormones released from the heart that reduce blood pressure, insulin resistance and body fat accumulation. Low NP levels may be associated with increased risk for type 2 diabetes, a condition more common in African-Americans and Hispanics than in white individuals.

In a recent PLOS ONE publication, Deepak Gupta, MD, MSCI, and colleagues examined serum NP levels from 3,220 multiethnic participants in the Diabetes Prevention Program, a randomized trial that investigated approaches to type 2 diabetes prevention.

They reported lower NP levels in African-Americans and Hispanics compared with white individuals. Over a two-year follow-up, NP levels remained lower in African-Americans compared with white individuals regardless of trial intervention.
