About 40% of this American Indian cohort had hypertension at baseline, and prevalence of hypertension was higher in older and obese study participants.
Chart Explanation: About 40% of this American Indian cohort had hypertension at baseline. Prevalence of hypertension was significantly higher among older and obese study participants, relative to their counterparts, but hypertension did not differ by gender.
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 4,533 Strong Heart participants had baseline information on hypertension status, by self-reported diagnosis, measured blood pressure >140/>90 mmHg, or reported use of antihypertensive medications.
