About one-half of this American Indian cohort were obese at baseline, and prevalence of obesity was higher among younger and female study participants.
Chart Explanation: More than 50% of this American Indian cohort were obese at baseline. Prevalence of obesity was significantly higher among younger and female 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 4,529 Strong Heart participants had baseline information on obesity status, by body mass index (BMI) >30 kg/m2.
