Sleep Quality and its Associated Factors among Nurses in a Tertiary Care Public Hospital in Puducherry District: A Cross-sectional Study

Abstract

Background: Adequate sleep is essential for human beings to maintain optimal health. Medical professionals, including nurses, work in stressful environments that could affect their sleep quality. The objective of this study was to determine the prevalence and the factors associated with poor sleep quality among nurses in a tertiary care public hospital. Materials and Methods: This cross-sectional analytical study was conducted on 1217 nurses aged between 21 and 60 years from May 2019 to April 2020 in a tertiary care public hospital in Puducherry. Sleep quality was assessed using the Pittsburgh sleep quality index scoring system, and the workplace stress scale was used to assess workplace stress. The Chi-squared test and adjusted Prevalence Ratio (aPR) were used to determine the factors associated with poor sleep quality. Results: The response rate was 99% (1217/1229), and three-fourths of the participants were women (943, 77.50%). The mean (SD) PSQI score was 4.49 (2.98), and more than one-third of participants, 42.80% (95% CI: 40.10-45.70), had poor sleep quality. The prevalence of poor sleep quality was significantly higher among women (z = 2.33, p = 0.019) aPR (95% CI): 1.08 (1.01-1.16), those having severe to dangerous levels of workplace stress (z = 8.22, p > 0.001) aPR (95% CI): 1.54 (1.39-1.71) and chronic pain (z = 2.11, p = 0.016) aPR (95% CI): 1.09 (1.02-1.17). Conclusions: The prevalence of poor sleep quality among the study population was high. This highlights the urgent need for implementing health promotion programs among nurses.
