Hazard ratios (HR) and 95% confidence intervals (CI) from multivariate Cox proportional hazards models for all-cause mortality according to categories of body mass index among African American participants without chronic illness^a at baseline who never smoked.

aChronic illness includes heart disease, stroke, or cancer (except non-melanoma skin cancer). Models adjusted for sex, education, marital status, alcohol consumption, and physical activity. Models stratified by cohort. Age-standardized death rates among referent BMI category (22.5-24.9) were 11.7, 6.8, and 7.8 per 1,000 person-years for males, females, and the total population, respectively. Age-standardized according to the US 2000 Standard Population using 5-year age increments. Hazard ratios (HR) and 95% confidence intervals (CI) from multivariate Cox proportional hazards models for all-cause mortality according to categories of body mass index among African American participants without chronic illnessa at baseline who never smoked.
