Summary

Introduction:

Healthcare professionals are exposed to a number of risk factors, including night work. The present study aimed to assess whether the incidence of cardiovascular disease endpoints (EP) differs in night work performing and non-performing healthcare professionals, with respect to the previously established risk of developing cardiovascular disease (CVD).

Methods:

To a sample of 3,210 workers of a large hospital, a risk of CVD was assigned according to the Framingham heart study between 2002 and 2007. For further evaluation, a group of healthcare professionals who had a given CVD risk above 10% (n = 240) was selected. In these individuals, data on the occurrence of EP in previous 10–15 years were found, the data were accessible to 175 people. A control group of 175 workers with a CVD risk below 10% was added to remove the influence of age and gender. The incidence of EP was compared in those performing and non-performing night work with regard to the overall risk of CVD.

Results:

In the group of 175 workers with CVD risk above 10%, there were 73 persons working at night, EP was recorded in 19.2% of them. In 102 night work non-performing healthcare professionals, the EP was recorded in 16.7% of them, the difference was not significant. In the control group, 82 healthcare professionals worked at night, 11.0% of them had EP, whereas 93 professionals of the group did not work at night, the EP was found at 10.8% of them, the difference was not statistically significant. A greater difference in the occurrence of EP was found when compared the EP incidence in a sample of night work performing professionals with CVD risk over 10% (19.2%) with a sample of night work non-performing professionals with CVD risk below 10% (10.7%), however, the difference was not significant (p = 0.1255) either.

Conclusion:

The incidence of EP was higher in night working healthcare professionals, especially in a connection with other risk factors of CVD, but the differences were not statistically significant. The limitation of the study is a small number of individuals in both groups. This issue requires further investigation.
