a
Quartiles of BAI and waist circumference were defined within each sex and BMI category. For example the lowest quartile of BAI among men with a BMI <25 kg m−2 ranged from 14.1 to 20.7, while the lowest quartile among men with a BMI ≥ 35 kg m−2 ranged from 19.6 to 30.7.
b
Values are percent of subjects with ≥3 risk factors (standard error).
c
Because of the small number of subjects who had multiple risk factors, a BMI < 25 kg m−2, and a low waist circumference, the lowest two categories of waist circumference were combined in this analysis.
