Obesity is a low-grade chronic inflammatory state, in which a cytokine chemerin with its immunometabolic modulation has an important role. We aimed to study in a healthy population relationships between serum chemerin levels, lifestyle choices and magnetic resonance imaging (MRI) assessed volumes of abdominal visceral (VAT) and subcutaneous (SAT) adipose tissues, which have different cytokine expression profiles. Overall, 73 healthy participants undertook lifestyle questionnaire and underwent anthropometric measurements along with MRI scanning of abdominal SAT and VAT. Furthermore, complete blood count was determined along with chemerin and fibrinogen serum levels. Regression model for prediction of chemerin serum levels was built after controlling for sex, age and anthropometric measures. Median serum chemerin was 141 (125-195) ng/mL. Serum chemerin had a moderate positive correlation with SAT and VAT volumes. The two most important predictors of chemerin levels were MRI detected SAT and thigh circumference. Independently, chemerin levels were associated with smoking, preference of salty food, and favoring flavor/simplicity of preparation over nutritional value of the food. Serum chemerin seems to be more strongly correlated with the volume of abdominal SAT than VAT, with certain lifestyle choices influencing chemerin levels independently of abdominal fat.
