Abstract

Abstract Background: Sleep disorder is becoming prevalent now a day due to shift work or irregular bedtime. Especially for health care providers, sleep disorder is one of the established yardsticks to measure the success of the services being provided in the healthcare organization. An estimated 150 million people worldwide and nearly 17% of the population in the developing nations are currently suffering from sleep problems. Objective: The objective of this study is to assess the prevalence of sleep disorder and associated factors among health care providers in UoGCSH, 2020. Methods: Institution- based comparative cross-sectional study was conducted from 01 February – 10 March /2020 for 514 participants, 246 from shift worker, and 242 non-shift workers. A simple random sampling technique was used to select 488 health care providers with a response rate of 94.94%. A self-administered questionnaire was used to collect relevant data for the study. The tools were checked for completeness, edited and entered into Epi Data version 3.1 then exported to SPSS version 20 for analysis. The binary logistic regression model was fitted to identify factors associated with sleep disorders. p-value < 0.05 and 95% confidence interval of AOR were used to declare statistical association. Results: Overall sleep disorder for a total 488 health care workers was 35.9% at 95% CI (31.6%-40.2%) whereas, the prevalence of sleep disorder among shift worker was 109 (44.3%) at 95%CI (38.2%-50.4%) and a non-shift worker were 68(28.1%) at 95% CI (22.7%-33. 5%).Variables like marital status, profession, experience and stimulant users were strongly associated with a sleep disorder. Participants who were single had developed 59.4% (OR: 0.406,95%CI (0.204-0.808) less likely to sleep disorder compared to married, non-stimulant users also had 55.4%(OR: 0.446,95%CI (0.231-0.863) less likely to develop sleep disorder than stimulant users, participants who work less than the mean year of seven years were 43.5% (AOR: 0.565,95%CI (0.353-0.905) less likely to developed sleep disorder compared to above seven years. According to profession those pharmacists and doctors were 58.5 (AOR: 0.415, 95% CI: 0.233-0.738) and 61.1% (AOR: 0.389, 95% CI: 0.183-0.826) less likely to develop sleep disorder compared to nurse. Conclusion and recommendation: The percentage of sleep disorders with shift workers was higher than non-shift health care workers. Therefore, to improve the sleep quality of health care providers developing a healthy shift work scheduling policy at a health facility is mandatory.
