Nearly one-half of this American Indian cohort had diabetes at baseline, and prevalence of diabetes was higher in older, female, and obese study participants.
Chart Explanation: About 46% of this American Indian cohort had diabetes at baseline. Prevalence of diabetes was significantly higher among older, female, and obese study participants, relative to their counterparts.
The Strong Heart Study consisted of several components and three study exams (baseline, 1989-1992; second exam, 1993-1995; and third exam, 1998-1999), followed by morbidity and mortality surveillance of 4,500 tribal participants. Strong Heart enrolled men and women aged 45-74 at baseline from 13 American Indian tribes/communities in Arizona, Oklahoma, and the Dakotas. A total of 4,458 Strong Heart participants had baseline information on diabetes status, by self-reported diagnosis, fasting glucose >126 mg/dl, or reported use of oral hypoglycemic medications or insulin.
