Prevalence of diabetes mellitus and related conditions in a south Texas Mexican American sample.

The prevalence of self-reported diabetes mellitus in a Mexican American sample population living in Hidalgo County in south Texas was examined along with risk for related sequelae. Data from a stratified random sample of 849 Mexican American men and women ages 45 and older were examined. A subsample of 193 diabetics was compared to 656 nondiabetics with respect to hospitalization, reasons for hospitalization, and other related medical conditions. The prevalence of self-reported diabetes for both men and women was 25.9%. Hospitalization rates for diabetics over a 1-year period and a 5-year period were significantly higher than nondiabetics. Hypertension, cardiac problems, amputations, kidney or urinary problems, eye problems, and joint and bone problems were significantly more common in the diabetics sample than in the nondiabetic sample. The data indicate that diabetes in Mexican Americans may be undertreated in south Texas.
