Answer

The severity and incidence of diabetic nephropathy are especially great in blacks (the frequency being 3- to 6-fold higher than it is in whites), Mexican Americans, and Pima Indians with type 2 DM. The relatively high frequency of the condition in these genetically disparate populations suggests that socioeconomic factors, such as diet, poor control of hyperglycemia, hypertension, and obesity, have a primary role in the development of diabetic nephropathy. It also indicates that familial clustering may be occurring in these populations.

By age 20 years, as many as half of all Pima Indians with diabetes have developed diabetic nephropathy, with 15% of these individuals having progressed to ESRD.
