Abstract

Metabolic syndrome is a cluster of disorders including central obesity, hypertension, dyslipidemia, and hyperglycemia. Today's metabolic syndrome definitions identify central obesity by waist circumference (WC) measurements. A recent pilot study suggests that cut-points derived from a waist-to-height ratio (WHtR), or Index of Central Obesity (ICO), is a more accurate measurement of central obesity. This study compared the association between the metabolic syndrome components and central obese parameters (ICO and WC) among the white, black, and Hispanic adults in the United States. The subjects' data was obtained from the 2005-2006 National Health and Nutrition Examination Survey. ICO was highly correlated with metabolic syndrome components among white subjects and the least correlated in Hispanic subjects. Multivariate logistic regression analysis did not indicate that ICO was a better parameter for metabolic syndrome than WC. Other WHtR cut-points may be more sensitive in predicting metabolic syndrome components than the values used in this study.
