Figure 1. Prevalence of diabetes and metabolic covariates versus trunk to leg volume ratio by BMI category.

The prevalence of diabetes (A), high triglycerides (B), low HDL (C), and high blood pressure (D) versus trunk to leg volume ratio quartile for normal BMI (> = 18.5 kg/m² and <25 kg/m²), overweight BMI (> = 25 kg/m² and <30 kg/m²), obese BMI (> = 30 kg/m²), and total population in NHANES 1999–2004 are shown below. All data displayed had a significant trend (P-for-trend <0.001) in prevalence versus quartile of trunk to leg volume ratio. There was a significant (P<0.001) interaction (trunk to leg volume ratio quartile & BMI category) in the prevalence of diabetes and high blood pressure.
