Circadian Variations of Mean Arterial Pressure in Men After Day- and Night-Shift-Work
open access
Abstract
Material and methods 50 healthy male shift-workers were included in the study. Mean arterial pressure (MAP) was analysed during 24 h after day shift and compared with the values of MAP after night shift. Aging, biological chronotype, obesity, the ratio of heart rate to respiratory frequency (HR/RF) were considered as a personal characteristics.
Results Obese subjects aging 40–55 years old, morning chronotype, HR/RF > 4 showed significant increase in blood pressure after night work.
Conclusion Aging, morning type of biological chronotype, obesity and value of the ratio HR/RF > 4 might be considered as a contraindications to the night work.
