Introduction. Lack of sleep contributes to maladaptive changes that cause metabolic disorders such as hypertension, cardiovascular disease, diabetes and obesity. Sleep problems can increase the risk of psychiatric disorders, somatic disorders, traffic accidents, and memory problems, as well as impaired overall body functioning. A growing body of evidence suggests that sleep disorders co-exist with other disorders, which are often interactive and bidirectional.
The aim of the study – to analyze sleep disorders in nurses of therapeutic and surgical departments who work in shifts and to establish possible relationships with the level of blood pressure.
Research Methods. 20 nurses from therapeutic departments and 20 from surgical departments who worked in shifts were included in the study. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) (in mm Hg) were measured according to a standard protocol. We used the “Pittsburgh Sleep Quality Index (PSQI)” to determine the sleep quality of nurses in therapeutic and surgical departments who work in shifts. The internal consistency of the scales of the “Pittsburgh Sleep Quality Index (PSQI)” questionnaire was checked using the Cronbach’s α method.
Results and Discussion. It has been established that the frequency of waking up in the middle of the night or early in the morning in nurses of therapeutic departments who work in shifts is influenced by age and length of shift work. The relationship between the frequency of awakenings and the frequency of night shifts during the month was also revealed in nurses of various profiles, but this association is lost in the case of employees of surgical departments when the frequency of night shifts increases during the month. Analysis of the relationship between awakenings in the middle of the night or early morning and arterial hypertension of all respondents included in the study showed a probable relationship between the frequency of awakenings and the level of systolic blood pressure in nurses of therapeutic departments, while such an association was not established in employees of surgical departments. At the same time, in the nurses of therapeutic departments who wake up 1–2 times a week in the middle of the night or early in the morning, the SBP level was probably higher compared to such data in the nurses of surgical departments.
Conclusions. In shift nurses, sleep disturbance is characterized by an increase in awakenings in the middle of the night or in the morning, which is interconnected with the level of blood pressure.
