Objective. We aimed to investigate whether lifestyle and body fat mass have an impact on the occurence of nonfunctional adrenal incidentalomas (NFAI). Methods. 100 patients with NFAI were included . 50 people constituted the control group. Physical activities of these groups were evaluated (using the International Physical Activity Questionnaire), smoking status was determined, anthropometric measurements were made. Body fat mass, fat percentage, total body water and fat free mass were measured using bioelectrical impedance method. Results. Body mass index (BMI), waist, hip, neck circumference, total body fat percentage and fat mass and smoking rate were found to be statistically higher in the patient group. Physical activities did not differ significantly. When a subgroup with similar age and BMI among was created, waist circumference and total fat mass were again significantly higher in the patient group. There was a significant positive correlation between the size of the adrenal mass and waist, neck circumference, BMI, and cortisol after 1 mg dexamethasone suppression test. Conclusion. The increase in the fat mass may have an impact on the development of NFAI. Although the patients were regarded as nonfunctional, suppressibility of the cortisol decreases as the mass size of the incidentaloma increases.
