Abstract:Objective: To explore the relationship between primary headache and sleep disorder in the medical population in Sanya city, so as to provide evidence for improving the prevention and treatment of primary headache in medical population. Methods: 280 doctors and 365 nurses at four hospitals in Sanya, were surveyed by stratified random cluster sampling.A structured questionnaire was used to collect demographic data, occupational factors and headache characteristics, and the Pittsburgh sleep rating scale was used to quantitatively score the sleep quality of medical staff. Results: The prevalence of headache in medical care in Sanya was 53.3%, the prevalence of primary headache was 50.0%, 43.1% in male medical workers and 56.9% in female.Among occupational factors, the number of night shift was closely related to sleep disorder. The grade correlation coefficient between the number of night shifts and the Pittsburgh Score of Sleep Disorders is closed related (Rho=0.18, P=0.00). The Pittsburgh score and headache were tested for grade correlation coefficient, resulting in Rho=0.287(P=0.00), suggesting that sleep was closely related to headache. There was a significant correlation between sleep disturbance and headache in the medical group(χ2=0.002,P=0.968). Sleep quality is closely related to primary headache(χ2=0.248,P=0.619). Conclusion: Medical workers in Sanya city have a higher incidence of headache than the normal people in China. The frequency of night shift greatly affects the sleep quality. The sleep quality is closely related to the primary headache.Therefore, scientific and reasonable arrangement of duty may improve the sleep quality and headache of medical staff.
