a  P<0.001 for comparison of prevalence by age and gender.

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.

Primary Data Source IndicatorPercentage of participants existing obesity at baseline exam, as indicated by study measurement of BMI (height and weight, in kg/m2), with >30 kg/m2 = obese
Primary Indicator Method of MeasurementExam

Pending DataPossible continued passive follow-up only
Additional Data Items of InterestAge, gender, diabetes, hypertension
Limitations of IndicatorOther measures of obesity such as waist circumference may better predict poor outcomes
Analytical ConsiderationsAnalysis performed by SHS investigators; denominators for each study exam and indicator must be defined properly
