  1. Abbreviations: P-int, P for interaction; HR, hazard ratio; CI, confidence interval; ABSI, a body shape index
  2. The data are presented as HRs (95% CIs) unless otherwise indicated. Analyses were adjusted for age (20–39, 40–59, or ≥ 60), sex (male or female), race/ethnicity (Mexican American, other Hispanic, non-Hispanic White, non-Hispanic Black, or other races), education level (below high school, high school, or above high school), family PIR (≤ 1.0, 1.1–3.0, or > 3.0), smoking status (never smoker, former smoker, or current smoker), drinking status (nondrinker, low–to–moderate drinker, or heavy drinker), PA (inactive, insufficiently active, or active), HEI (in quartiles), and CCI (continous) when they were not the strata variables
