Introduction: Many occupational factors, including occupational stress, may interfere with sleep. Sleep problems (SPs) can, in turn, endanger the health and safety of workers. The purpose of this study was to verify whether SPs are associated with metabolic syndrome (MetS).
Materials and Methods: The quality of sleep was investigated in three groups of workers during their periodical medical examination at work, by means of the Pittsburgh Sleep Quality Index (PSQI). MetS was defined as the co-occurrence of three or more of the known cardiovascular risk factors: obesity, hyperglycaemia, low HDL-cholesterol, hypertriglyceridemia, and hypertension. The group A was composed by 2226 persons (male 32.3%, age 47.69.4 years), group B by 741 persons (male 35.4%, age 47.210.7), and group C by 1042 persons (male 34.5%, age 45.811.3).
Results: In all three groups, using logistic regression analysis adjusted for age and gender, the PSQI score was a significant predictor of MetS. The Adjusted Odds Ratios were: 1.099 (CI95% 1.056;1.142, p<0.001) in group A; 1.075 (CI95% 1.011; 1.144, p<0.05) in group B; 1.075 (CI95% 1.022; 1.132, p<0.01) in group C.
Conclusions: SPs are consistently associated with cardiovascular risk factors and play a mediating role in the relationship between occupational stress and MetS. A correct sleep hygiene could help to
reduce the incidence of cardiovascular risk factors at work.
