Abstract

Background In hypertensive patients sleep deprivation induced increase in blood pressure. Several data indicate an occurrence of cardiovascular diseases in shift workers. In this study we investigate characteristics, which suggest a worse adjustment to the night work, exhibited as an increase in blood pressure.
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.
