Abbreviations: OR, prevalence odds ratio; CI, confidence interval; BMI, body mass index; WHR, waist-hip ratio; WC, waist circumference; REF, referent
NOTE: Missing values ranged from 0 (age) to 383 (WHR). The adjusted model consists of 1,600 (BMI), 1,414 (WHR) 1,415 (WC) whites and 308 (BMI), 269 (WHR), and 269 (WC) African Americans.

Adjusted for sex, smoking, age, physical activity, red meat consumption, total fat intake, and total fiber intake
b
High WHR was defined as greater than 0.9 and 0.85 for men and women, respectively. WC above 102 cm in men and 88 cm in women was considered high (12).
