Figure 2

Logistic regression analyses of the effects of BMI, WC, and WHtR on insulin resistance. NFG: normal fasting glucose; IFG: impaired fasting glucose; BMI: body mass index; WC: waist circumference; WHtR: waist-to-height ratio. Model was adjusted for age, gender, education (less than high school, high school or equivalent, or college or above), marital status (married or unmarried), smoking status (current smoker, former smoker, or never smoked), alcohol use (currently, formerly, or never), physical activity (yes or no), TC, TG, LDL, HDL, family history of diabetes (yes or no), glucose, and HbA1c.
