SAT-160 Evaluation of Life Style and Anthropometric Parameters in Patients with Nonfunctional Adrenal Incidentalomas

Introduction Adrenal lesions that are found incidentally during routine imaging of people who do not have any complaints or physical findings related to adrenal gland are called adrenal incidentaloma (1,2). Incidentalomas appear more frequently with the increasing use of imaging techniques and increasing age. It is unclear why most of these masses emerged. It is controversial whether nonfunctional adrenal incidentalomas (NFAI) increase the risk of cardiovascular disease or metabolic syndrome or are more common in people with these diseases. In this study, we aimed to investigate whether lifestyle and body fat have an impact on the occurrence of NFAI. Materials and Methods 100 patients with NFAI were included in the study. Control group consisted of 50 healthy and similar age groups. Physical activities of these groups (with the International Physical Activity Questionnaire Short Form), smoking were questioned and anthropometric measurements were made (Height, body weight, body mass index (BMI), neck, hip, waist circumference and body fat mass, fat percentage, total body water, fet free mass with bioimpedance method). Laboratory tests were examined from the patient file. Results Female dominance was observed in patients with NFAI. BMI, waist circumference, hip circumference, neck circumference, total body fat percentage and mass and smoking were found to be higher in the patient group compared to the healthy group and a statistically significant difference was found. When a subgroup of patients with similar age and BMI among the patients and the control group were constituted (25-29,99 kg / m(2)) waist circumference and total fat mass were again significantly higher in the patient group compared to controls. In addition, there was a significant positive correlation between mass size and waist circumference, BMI, neck circumference, cortisol after 1 mg dexamethasone suppression test and a significant negative correlation with ACTH. Conclusion The data obtained showed that body adiposity and smoking were higher in patients with NFAI. Also, ıt was shown that although the patients were regarded as nonfunctional, suppressibility of the cortisol decreases as the mass size of the incidentaloma increase. Resources 1.
