title: [NIGHT SHIFT WORK AND HEALTH DISORDER RISK IN FEMALE WORKERS].
abstract: There was evaluated the risk to health in females employed in shift work, including night shifts. According to the data of periodical medical examinations health indices of 403 females employed in shift work, including night shifts, were compared with indices of 205 females--workers of administrative units of the same enterprise. Overall relative risk (RR) for the health disorder associated with the night shift was 1.2 (95%; confidence interval (CI): 1.09-1.28). A statistically significant increase in risk was observed in relation to uterine fibroids (OR 1.3; 95% CI: 1.06-1.54), mastopathy (OR 1.4; 95% CI: 1.2-1.6), inorganic sleep disorders (OR 8.8; 95% CI 2.6-29.8). At the boundary of the statistical significance there was the increase in the risk for obesity (OR 1.2; 95% C: 0.97-1.39), hypertension (OR 1.2; 95% CI, 0.9-1.5) and endometriosis (OR 1.5; 95% CI: 0.98-2.16). There was revealed an adverse effect of night shifts on the gestation course: ectopic pregnancy in the experimental group occurred 6.6 times more frequently than in the control group (95% CI: 0.87-50.2), and spontaneous abortion--1.7 times (95% CI: 0.95-3.22). The performed study has once again confirmed the negative impact of smoking on women's reproductive health: smoking women in the experimental group compared with the control group smokers had 2.7 times increased risk of uterine fibroids (within 1.06-7.0), the risk in non-smokers was significantly lower--1.2 (0.98-1.4). The findings suggest about a wide range of health problems related to employment on shift work, including night shifts, which indicates to the need for adoption of regulatory and preventive measures aimed to this professional group.
