Fetuin A is an inhibitor of insulin action and have been found to be related with subcutaneous lipid accumulation and insulin resistance. The relation of cardiac lipid accumulation, fetuin A and insulin resistance parameters in obese children is not well-known. The aim of the study was to evaluate the relation of serum fetuin A levels with subcutaneous and cardiac lipid accumulation, and insulin resistance parameters in Turkish obese children. Serum fetuin A levels, cardiac and subcutaneous lipid accumulation parameters of 42 obese (10.9±2.3 years, 19 female) and 40 control group subjects (11.2±2.7) were compared. Cardiac lipid accumulation measured by subepicardial adipose tissue thickness. Insulin resistance was assessed using homeostasis model assessment (HOMA-IR) index. There were significant correlations serum fetuin A levels with BMI-SDS, circumferences of waist, hip and midarm, SATT and HOMA-IR (r=0.362, p=0.018, r=0.728, p=0.001, r=0.662, p=0.0001, r=0.713, p=0.0001, r=0.477, p=0.001, and r=0.330, p=0.038 as, respectively). Fetuin A was correlated well with cardiac and subcutaneous lipid accumulation, insulin resistance parameters, which may be related with early pathogenetic mechanisms of metabolic obesity complications in children.
