[Assessment of lipid profile in non-smoking and smoking young health persons].

The coexistence of hypertension, obesity and dyslipidemia constitutes combination of factors, which in adulthood and old can generate atherosclerotic-dependent disease entities. Cigarette smoking, which is considered a major risk factor for atherosclerosis and coronary heart disease, may lead to changes in normal plasma lipid profile. The aim of the study was to evaluate the effect of cigarette smoking on lipid parameters and the concentration of lipid peroxidation products in young healthy persons. The study population consisted of 57 healthy volunteers aged 19-26 years. They were qualified to planned analyzes based on research conducted by primary care clinicians. The study population was divided into smokers and non-smokers on the basis of determining the concentration of cotinine (ELISA method). It has been shown that concentrations of lipid profile parameters in the study groups remained within the reference ranges, however, in the group of smoking healthy persons were higher as compared with non-smoking healthy persons, except HDL cholesterol. It has been demonstrated 1.5 times higher concentration of LDL cholesterol in the serum of smokers (112.8 ± 37.9 mg/dl) when compared to non-smoking subjects (77.6 ± 43.7 mg/dl, p=0.006). There was a significant difference between the mean value in the group of triglycerides of healthy non-smokers (72.9 ± 24.1 mg/dl) and the average value of those in smokers (93.9 ± 40.3 mg/dl, p=0.034). There was a significant difference between the mean value of the concentration of lipid peroxidation products reacting with thiobarbituric acid (TBARS) in the non-smoking healthy persons (0.5 ± 0.3 mmol/l), and the mean value of TBARS in the group of smoking persons (0.8 ± 0.6 mmol/l, p=0.019). The results show that cigarette smoking may be an important factor in potential changes in lipid profile already in young healthy people, which in the future may result in the onset of atherosclerosis and coronary heart disease.
