Chemerin levels are positively correlated with abdominal visceral fat accumulation.

Abstract

OBJECTIVE: Chemerin, a recently discovered adipocytokine, may be linked to obesity and obesity-associated metabolic complications. However, the relationship between visceral fat accumulation and chemerin is still unknown. Therefore, we investigated the relationship between serum chemerin levels and body composition as measured by computed tomography (CT).

PATIENTS: We recruited 173 men and women without histories of diabetes or cardiovascular disease.

MEASUREMENTS: Biomarkers of metabolic risk factors and body composition by computed tomography were assessed. Serum chemerin levels were measured by enzyme-linked immunosorbent assay.

RESULTS: Chemerin levels correlated with body mass index (BMI), waist circumference, abdominal visceral fat area, blood pressure, fasting insulin, homoeostasis model of assessment-insulin resistance, total cholesterol, triglyceride, creatinine, aspartate aminotransferase and alanine aminotransferase. By stepwise multiple regression analysis, abdominal visceral fat area, blood pressure and total cholesterol levels independently affected chemerin levels.

CONCLUSIONS: Abdominal visceral fat accumulation, blood pressure and lipid profile were significantly associated with serum chemerin levels. Our findings suggest that chemerin may be a mediator that links visceral obesity to cardiovascular risk factors.
