Sleep disorder status of nurses in general hospitals and its influencing factors.
BACKGROUND
This study aimed to evaluate the current sleep disorder status of nurses in general hospitals and analyze its influencing factors.


METHODS
A total of 2,033 nurses who have worked for 6 months in 3 general hospitals, namely, The First Affiliated Hospital of Harbin Medical University, The Second Affiliated Hospital of Harbin Medical University, and The Third Affiliated Hospital of Harbin Medical University, were selected by random sampling from April 2015 to November 2015 and investigated. The Effort-Reward Imbalance Questionnaire (ERI) and Job Content Questionnaire (JCQ) were applied to evaluate occupational stress. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep disorder status of the research subjects. Logistic regression analysis was adopted to determine the influencing factors of nurses' sleep disorders.


RESULTS
The average PSQI score of 2,003 research subjects is 7.26±3.56, including 860 subjects with PSQI ≥8, accounting for 42.9%. The female research subjects in the department of gynecology and obstetrics, emergency department, and ICU show high risks of sleep disorders (i.e., many years of working; job title: registered nurse; many times of night shift per month; no frequent exercise; many efforts and few rewards; high decision-making autonomy). Educational background and marital status did not exhibit statistical relevance with sleep disorders.


CONCLUSIONS
The sleep disorder status of nurses in general hospitals is closely related to occupational stress. As such, nurse managers should focus more attention to the influencing factors of nurses' sleep disorders and relieve their occupational stress to reduce the occurrence rate of sleep disorders.
