Today I came across a study on prevalence of Diabetes among African Americans and European Americans. From the article:
The study, available online in advance of publication in the October 2009 edition of the Journal of General Internal Medicine, found that when African Americans and whites live in similar environments and have similar incomes, their diabetes rates are similar, which contrasts with the fact that nationally diabetes is more prevalent among African Americans than whites.

Not sure whether generally Population geneticists overlook to nullify 'other conditions'. Though some of the race promoters may do so.
