Abstract: Metabolic syndrome (MS) is an important cardiovascular risk factor and visceral fat plays a central role in its development. Visceral fat measurement by TC or MRI is difficult to apply in routine clinical practice. Our aim was to evaluate anthropometric measurements, abdominal ultrasonography (US) and a new abdominal bioelectrical impedance analysis (BIA) (ViScan, TANITA) as predictors of metabolic abnormalities. 105 subjects, (age 52.8 ± 14.7 years, BMI of 29.2 ± 5.3 kg/m2) were analysed. Total cholesterol, HDL-cholesterol, triglycerides, glucose, insulin, adipochine and inflammatory citochines were determined. Waist and hip circumferences and sagittal abdominal diameter (SAD) were measured and abdominal BIA with ViScan was performed; peri-renal, para-renal, peri-hepatic, pre-peritoneal, and peritoneal fat thicknesses were measured by US Anthropometric indexes, ViScan and US measurements were evaluated as predictors of MS abnormalities in a partial correlation analysis adjusted for BMI. Only SAD and peritoneal US fat thickness are good predictors for the metabolic abnormalities related to MS after adjusting for BMI. The correlation among different anthropometric, abdominal BIA and ultrasonographic measurements, corrected for BMI, showed that SAD had a strong correlation with peritoneal fat thicknesses. Both SAD and US peritoneal fat thickness are good predictors of metabolic abnormalities.
