INTRODUCTION Obesity can be defined as an excessive accumulation of health threatening body fat, caused by positive energetic balance. It can be classified according to body mass index as normal body mass, excessive body mass, significant obesity and extreme obesity. According to WHR (waist-hip ratio), it can be classified to android and gynoid type depending on fat tissue distribution. Android type has greater frequency of cardiovascular and metabolic complications, as is occurrence of premature atherosclerosis. As metabolic complications we consider lipid status disorders in obese workers, and these complications are related to body composition. MATERIAL AND METHODS Among 331 workers, we separated 95 persons with BMI > 30 kg/m2. This group was classified according to gender, their body composition has been measured using bioelectri-cal impedance method and, subsequently cholesterol, triglycerides, HDL and LDL levels were determined, searching for relationship of body composition with lipid status fractions p< 0.05. RESULTS High body fatty was found in 33.03% of male and in 37.48% of female subjects. It was found that in male subjects cholesterol levels (6.70 mml/L),triglycerides (2.56 mml/L), limit values of LDL (3.93 mml/Lć and limit values of HDL (1.16 mml/L) were highly risky. Positive insignificant relationship of body fatty mass with cholesterol, triglycerides, LDL, but not with HDL was found. DISCUSSION Results point to highly risky limit values of lipid parameters in male and female subjects. These values can be explained by older age of subjects, their way of life and nutrition regimen, significant comorbidity in this group, and influence on working ability. CONSLUSION It was found that obese male and female subjects have high values of body fatty mass, Male subjects have highly risky levels of lipid status fractions, while in female subjects these are limit values. Insignificant positive correlation of body fatty mass with lipid status fractions in tested population was found. The obtained results are significant regarding morbidity expectation and studies of complications of obese working population, as well as in judgment of working ability.
