Abstract

Objective: this study set out to investigate the association between abdominal obesity ultrasound measurements, waist circumference and body mass index (BMI), metabolic syndrome (MS) components and subclinical atherosclerosis. Methods: sixty patients were recruited and divided equally into two groups, according to the presence of MS. All subjects had an ultrasound examination for measurement of visceral and subcutaneous fat thickness and carotid IMT. Results: the values of visceral fat thickness, preperitoneal circumference and carotid IMT were higher in patients with MS than in control subjects. Visceral fat thickness showed significant correlations with many cardiovascular risk factors (waist circumference, BMI, fasting plasma glucose, HDL and LDL cholesterol). All abdominal obesity measurements were correlated with BMI. Carotid IMT showed correlations with age, visceral fat and preperitoneal circumference. Visceral fat was independently associated with systolic and diastolic blood pressures and fasting plasma glucose. Systolic and diastolic blood pressures and BMI were independent determinants of carotid IMT. Conclusion: visceral fat thickness showed the best correlation with MS components, suggesting that it could be a useful parameter in cardiovascular risk assessment. Age, systolic and diastolic blood pressures and BMI were independent determinants of subclinical atherosclerosis. MS was associated with a higher carotid IMT.
