Assessment of Sleep Quality Among Physicians Working at Tertiary Care Centers in Saudi Arabia: A Cross-Sectional Study
Abstract
Background Adequate sleep is essential for physicians to maintain alertness, accuracy, and emotional stability in clinical care. However, no studies focused solely on physicians, particularly in Saudi Arabia. Objective To determine the prevalence and determinants of sleep quality among physicians in tertiary care centers in Saudi Arabia. Methods A cross-sectional survey was conducted between January and March 2025 using the validated Pittsburgh Sleep Quality Index (PSQI). Demographic, occupational, and lifestyle data were obtained through an electronic questionnaire. Poor sleep quality was defined as a global PSQI score >5. Bivariate analyses used the chi-square test, and multivariable logistic regression estimated adjusted odds ratios (aOR) with 95% confidence intervals (CI). Results A total of 412 physicians participated (61% male; 72% aged 20–39 years). The mean PSQI score was 8.6 ± 3.1 (median = 8), and 75.2% (95% CI: 71.1–79.4) of physicians were classified as poor sleepers. Shift work (aOR 2.58, 95% CI 1.61–4.13) and on-call duties (aOR 1.76, 1.12–2.76) significantly increased the odds of poor sleep. Later, bedtimes (1:00–3:00 AM; aOR 3.12, 1.98–4.91), prolonged daytime naps (>30 min; aOR 2.95, 1.65–5.26), and screen use before sleep (aOR 1.67, 1.08–2.61) were also associated with poorer sleep quality. Being married (aOR 0.47, 0.33–0.69), having children (aOR 0.51, 0.32–0.81), and avoiding caffeine ≥6 hours before bedtime (aOR 0.50, 0.27–0.90) were protective.…
