Prevalence of metabolic syndrome versus trunk to leg volume ratio quartile by BMI, gender, race/ethnicity, and age.

The prevalence of metabolic syndrome versus trunk to leg volume ratio quartile is displayed below for (A) BMI category, (B) gender, (C) race/ethnicity, and (D) age group in NHANES 1999–2004. (A) All data displayed by BMI category had a significant trend (P-for-trend<0.001) in metabolic syndrome versus trunk to leg volume ratio quartile; there was also a significant interaction (P-for-interaction<0.001) between trunk to leg volume ratio quartile and BMI category for metabolic syndrome. (B) All data displayed by gender had a significant trend (P-for-trend <0.001) in mortality versus trunk to leg volume ratio quartile; there was also a significant interaction (P-for-interaction<0.001) between trunk to leg volume ratio quartile and gender for metabolic syndrome. (C) All data displayed by race/ethnicity had a significant trend (P-for-trend<0.001) in metabolic syndrome versus trunk to leg volume ratio quartile; there was also a significant interaction (P-for-interaction<0.05) between trunk to leg volume ratio quartile and race/ethnicity for metabolic syndrome. (D) All data displayed by age group had a significant trend (P-for-trend<0.001) in metabolic syndrome versus trunk to leg volume ratio quartile; there was also a significant interaction (P-for-interaction<0.001) between trunk to leg volume ratio quartile and age group for metabolic syndrome.
