The relationship between sleep disorders and hypertension and shift work in medical staff of Shahid Mohammadi Hospital

Introduction: Low quality sleep and insomnia can lead to impaired daily functioning, increased human errors, and occupational accidents. Shift work is one of the factors affecting insomnia and sleep quality. The aim of this study was to investigate the relationship between sleep disorders and blood pressure and shift working in Shahid Mohammadi hospital staff. Methods: This descriptive cross-sectional study was performed on 263 clinical staff of Shahid Mohammadi hospital in Bandar Abbas city in 2019, who were selected using random sampling method. In addition to demographic data, Maureen Insomnia Severity Index, shift working status, and blood pressure of the participants were recorded. Data were analyzed using spss version 24 software and logistic regression, chi-square, and t-test tests. Results: The results showed that 39(14.8%) participants had normal sleep and 118(44.9%), 90(34.2%), and 16(6.1%) of the subjects had mild, moderate, and severe sleep disorders, respectively. Sleep disorders were higher in women compared to men (P-Value⩽0.05). Compared to day workers, the odds ratio of sleep disorders in shift workers was 3.50 (P-Value⩽0.05). There was no significant relationship between hypertension and shift working and sleep disorders (P-Value≥0.05). Conclusion: Since the prevalence of insomnia in hospital staff is high and shift working increases the risk of sleep disorders, shift working schedules should be considered and adjusted.
