Trends in diabetes prevalence and diabetes-related complications in older Mexican Americans from 1993-1994 to 2004-2005

OBJECTIVE: Evidence has shown that Mexican Americans have a higher prevalence of diabetes and a greater risk for diabetes-related complications than non-Hispanic whites. However, no studies have described the changes in prevalence among older Mexican Americans. The purpose of this study was to expand on the current literature by examining the trends in diabetes prevalence and diabetes-related complications in Mexican Americans aged >or=75 years from 1993-1994 to 2004-2005. RESEARCH DESIGN AND METHODS: The prevalences of self-reported diabetes and diabetes-related complications were estimated in the original cohort (1993-1994) and the new cohort (2004-2005) of the Hispanic Established Population for the Epidemiologic Study of the Elderly (Hispanic EPESE) and were compared across the two surveys. RESULTS: The prevalence of diabetes among Mexican Americans aged >or=75 years has nearly doubled between 1993-1994 and 2004-2005 from 20.3 to 37.2%, respectively (P
