INTRODUCTION - Shift workers have an impaired circadian rhythm, which might have an adverse effect on their health. In order to assess cardiometabolic risk in shift workers, a cross-sectional study was performed among active workers (aged 25-66 years, with a minimal shift working experience of 5 years). METHODS - In total 481 workers (121 men, 360 women) registered by the occupational health service were enrolled in our study. Most participants worked in the light industry (58.2%) or in public service (23.9%). Following questionnaire-based data recording, anthropometric measurements and physical examination were performed and fasting venous blood sample was taken for measuring laboratory parameters. Data from shift workers (n=234,54 men and 180 women, age: 43.9±8.1 years) were compared with those of day workers (n=247, 67 men and 180 women, age: 42.8±8.5 years). RESULTS - Compared with day workers, shift workers had bigger weight (76.6±16.1 vs 73.9±17.6 kg; p<0.05), higher BMI index (27.5±5.3 vs 26.0±4.9 kg/m2; p<0.01) and systolic blood pressure (123+19 vs 119±16 mmHg, p<0.01), and higher prevalence rate of diabetes (4.3 vs 1.2 %; p<0.05) and cardiovascular diseases (3.8 vs 0.8 %; p<0.05). In addition, the proportion of participants who performed regular physical activity was lower (20.6 vs 38.7 %; p<0.001) and that of current smokers were higher (35.0 % vs 19.5 %; p<0.001) in shift workers than in day workers. In laboratory findings, only one difference has been found: HDL-cholesterol level was lower among women (shift workers versus workers: 1.56±0.32 vs 1.68±0.36mmol/ l;p<0.01). CONCLUSION - Long-term shift work (day-night) results in a less healthy lifestyle and worse cardiometabolic risk factors compared with day work. Thus, our study highlights the importance of measures for preventing cardiovascular diseases in shift workers.
