aMultivariable models were stratified by cohort and used attained age as the underlying time metric. All multivariable models adjusted for race (white, black, Asian, other, or unknown), education (less than high school, high school graduate, some college, college graduate, postgraduate, or unknown), marital status (married, divorced, widowed, single, or unknown), grams of alcohol consumption (quartiles or unknown), overall physical activity level (cohort-specific quintiles or unknown), and smoking status (never smoked, former smoker who quit <20 years ago, former smoker who quit 20 or more years ago, former smoker but unknown number of years since quitting, smoker but unknown if current or former, current smoker, or smoking status unknown).

bMale (M)-specific cut points for each category of waist circumference: category 1 (<90), category 2 (90 to <100), category 3 (100 to <110), category 4 (≥110). Female (F)-specific cut points for each category of waist circumference: category 1 (<70), category 2 (70 to <80), category 3(80 to <90), category 4 (≥90).

cP value, test for interaction by sex.

dIn addition to the covariates listed in footnote 1, this model was also adjusted for body mass index at baseline (continuous).

eMale-specific cut points for each category of waist-to-hip ratio: category 1 (<0.90), category 2 (0.90 to <0.95), category 3 (0.95 to <1.0), category 4 (≥1.0). Female-specific cut points for each category of waist circumference: category 1 (<0.75), category 2 (0.75 to <0.80), category 3 (0.80 to <0.85), category 4 (≥0.85).
