Hypertensive Waist: First Step of the Screening for Metabolic Syndrome

Abstract

BACKGROUND: In previous studies, we have suggested that hypertensive waist is a frequent combination in persons with metabolic syndrome. The objective of the current study was to analyze the ability of hypertensive waist to predict the presence of the metabolic syndrome. METHODS: A total of 1294 women and men, randomly selected from general population, aged > or =18 years were included in this study. For these persons, the clinical and anthropometric data as well as fasting plasma blood glucose, triglycerides, total cholesterol, and high-density lipoprotein cholesterol were assessed. Hypertensive waist was defined as the presence of the systolic blood pressure > or =130 mmHg or a diastolic blood pressure > or =85 mmHg or history of treated hypertension plus a waist circumference > or =80 cm for women and > or =94 for men. International Diabetes Federation criteria were used for the diagnosis of the metabolic syndrome. RESULTS: The prevalence of hypertensive waist was 43.3% and the prevalence of the metabolic syndrome was 45.7%. Persons with hypertensive waist were 6.7 times more likely to have metabolic syndrome (95% confidence interval, 5.5-8.2) when compared with people without hypertensive waist. The high values of specificity (84%) and sensitivity (80.4%) showed that hypertensive waist is a very good predictor of the metabolic syndrome. CONCLUSIONS: On the basis of the easy-to-determine clinical parameters and on high predictive value, the clinical couple of hypertensive waist could be used as a starting point to screen for metabolic syndrome in Romanian population.
