Haffner et al. (1991) conducted a cohort in Type II diabetes mellitus (n=923). Mexican American ethnicity vs. Non-Hispanic white ethnicity was evaluated on 8-year incidence of type II diabetes (OR 2.72, 95% CI 1.02-7.28). Mexican Americans had a significantly higher 8-year incidence of type II diabetes compared to non-Hispanic whites (6.5% vs 2.0%; adjusted OR 2.72, 95% CI 1.02-7.28).
