On the issue of assessing the blood lipid spectrum in working men of different ages

Introduction. Harmful working conditions contribute to the development of dyslipidemia

Goal — assessment of the blood lipid spectrum in men of different age groups under conditions of occupational stress.

Materials and methods. We analyzed the lipid spectrum of the blood in men aged up to 40 years (groups No. 1, 2 with different work experience, n=22 and n=20) and over 40 years of age (group No. 3, n=20). Assessed working conditions. Nutritional status, diet, physical activity, tobacco smoking, and alcohol consumption were determined.

Result. Working conditions are harmful in terms of tension of 3.2 degrees. Physical activity is insufficient, 47.3% have three meals a day, 52.7% have two meals a day. In groups under 40 years of age with different years of experience, 68.2% and 63.2% are overweight; in people over 40 years old, 55.0% are overweight, class I obesity. at 20.0%. The proportion of smokers is 4.5%, 10.0% and 20.0%. With increasing age and experience, triglycerides increased (from 1.12±0.95 to 1.53±0.94 (p=0.022), total cholesterol (from 5.04±1.22 to 6.31±1.2, p=0.001), low-density lipoproteins (from 3.8±0.98 to 4.83± 1.11, p=0.01) mmol/l; proportions of people with hypertriglyceridemia (from 9.1 to 43.8%), hypercholesterolemia (from 40.9% to 93.7%), high LDL-C (from 47.6 to 93.75%); in subgroup No. 1, 19.0%, No. 2, 33.4% had HDL-C below normal. Lipid atherogenicity increased from 3.34±0.13 to 3.95±0.27 (p=0.031).

Limitations. Men under 40 and over 40 years of age with varying years of experience working in hazardous work conditions.

Conclusion. Hard work with poor nutrition and physical inactivity contributes to atherogenic changes in blood lipids. It is proposed to expand the list of studies to assess the atherogenicity of lipids in trained workers; in people with strenuous work, determine at an earlier age for the prevention of cardiovascular diseases.
