THE RELATIONSHIP BETWEEN SEX STEROIDS, INSULIN RESISTANCE AND BODY COMPOSITIONS IN OBESE WOMEN: A CASE-CONTROL STUDY

Abstract

Background: Obesity causes many health problems and affects the quality and duration of life negatively. We aimed to investigate the relationship between sex steroids, insulin resistance and body compositions in obese women. Methods: This study was carried out on a sample of 150 pre-menopausal women who were referred to the Outpatient Clinic of Family Medicine between 2014–2015. A survey about their socio-demographic characteristics was carried out, and anthropometric parameters were measured. LDL-C, HDL-C, total cholesterol, triglyceride, glucose, insulin, sex hormone binding globulin (SHBG), estradiol, dehydroepiandrosterone sulfate (DHEA-S), total/free testosterone levels were measured in the blood. Body compositions were assessed with a bioelectrical impedance device. For insulin resistance, Homeostasis Model Assessment (HOMA-IR) was calculated. Results: In our study, a significant association was found between high glucose, total cholesterol, LDL-C, TG, insulin, insulin resistance and low HDL-C, SHBG, DHEA-S levels with obesity (p<0.05). There was no statistically significant relationship between estradiol, total/free testosterone and obesity (p>0.05). Conclusions: In our study, high glucose, total cholesterol, LDL-c, TG, insulin, insulin resistance and low HDL-C, SHBG, DHEA-S levels were associated with obesity. This relationship leads to many diseases, especially diabetes mellitus and cardiovascular disease. Therefore, obesity is a disease that needs to be monitored closely, frequently and treated properly.
