BACKGROUND: To assess the metabolic profile and the prevalence of the metabolic triad (i.e. hyperinsulinaemia, hyperapobetalipoproteinaemia, and decreased low-density lipoprotein particle size) in women characterized by the hypertriglyceridaemic waist (HTGW) phenotype and to identify cut-off values for triglycerides and waist circumference, effectively discriminating women with the metabolic triad. METHODS: Two hundred and twenty-eight female subjects without any history of vascular disease or diabetes mellitus attending an Outpatient Lipid Clinic setting at the University Hospital of Ioannina, Greece were studied. RESULTS: Currently available HTGW criteria for women were unable to detect any significant differences in the metabolic profile either in the pre- or post-menopausal women, and proved similar in terms of sensitivity and specificity in identifying women with the metabolic triad. A cut-off value of 1.26 mmol/L for triglycerides and 84.5 cm for waist circumference were determined by Receiver-operating Curve evaluation. Women with both triglycerides and waist circumference above these thresholds had four-fold higher odds of presenting with the metabolic triad compared with women with non-HTGW phenotype. CONCLUSIONS: A HTGW phenotype definition of 1.26 mmol/L for triglycerides and 84.5 cm for waist circumference may effectively identify Mediterranean women with the atherogenic metabolic triad. Whether these criteria are also associated with a higher incidence of vascular disease and/or new-onset diabetes in women remains to be investigated. Copyright (c) 2008 John Wiley & Sons, Ltd.
