Some quotes from my not-so-random web surfing:
African-Americans and Latinos, particularly Mexican-Americans and Puerto Ricans, incur diabetes at close to twice the rate of whites.
The rates of type 2 diabetes are 110% higher among Mexican Americans and 120% higher among Puerto Ricans than among non-Hispanic whites.
While depression affects maybe three or five percent of the population at any given time, the rate is between 15 and twenty percent in patients with diabetes, according to the American Diabetic Association. Women, in particular are at greater risk, according to other studies.
