| Abstract: | AIMS: The objective of this prospective study was to assess the correlation between carotid intima-media thickness at the common carotid (CIMTc) and carotid bifurcation (CIMTb) level, hepatic fat accumulation, and obesity phenotypes. MATERIAL AND METHODS: Two hundred obese adults, in which CIMTc and CIMTb thickness was determined, were included. According to body mass index (BMI) and presence of metabolic syndrome (MetS), patients were classified as metabolically healthy obese (MHO, obesity without MetS) and metabolically unhealthy obese (MUHO, obesity with MetS). MHO patients were further classified as MHO1 (obese with increased waist circumference) and MHO2 (obese with increased waist circumference plusone of the 4 criteria for MetS). Non-alcoholic fatty liver disease (NAFLD) presence was assessed by fatty liver index (FLI). RESULTS: CIMTc and CIMTb increased with obesity phenotypes from 0.74 mm and 1.04 mm in MHO1 to 0.84 mm and 1.23 mm in MHO2 and 0.88 mm and 1.74 mm in MUHO. Obesity phenotypes were significantly correlated with CIMTb. NAFLD frequency increased from 66.0% in the MHO1 to 73.0% in the MHO2 and 84.2% in the MUHO (p<0.05). Independent of age, BMI, total cholesterol, HbA1c, and HOMA-IR, the CIMTc was significantly associated with FLI in all obesity phenotypesand CIMTb only in MHO2 and MUHO. CONCLUSIONS: Our results suggest that subclinical atherosclerosis varies according to obesity phenotypes and is correlated with the hepatic fat accumulation. |
