Background: Sufficient sleep is necessary for optimal human health. Short-term sleep deprivation can negatively affect individuals' alertness, mood, attention and concentration; long-term sleep deprivation is associated with chronic diseases and mortality.

Aim of study: Measuring sleep quantity, assessing sleep quality and determining risk factors of sleep disturbance among Minia University hospitals' workers.

Subjects and methods: This study is a cross sectional study conducted for identification of sleep disorders among 311 Minia University hospitals' workers; (104 doctors, 104 nurses and 103 clerks), using a questionnaire which included demographic characteristics, assessment of sleep, family work conflict (FWC) and emotional exhaustion.

Results: Sleep score ranged (0-16) with mean (3.9 ± 4.01), about (92%) of the studied workers had a little frequency of sleep disturbance and (8%) had a high frequency of sleep disturbance, Sleep score was higher among doctors (6.08) than nurses (3.7) and Clerks (1.9) with statistically significant difference. FWC score (10-25) with mean (16.4 ± 2.5), Emotional exhaustion score (0-53) with mean (17.4 ± 16.9). Odds ratio for night shift work, FWC score and emotional exhaustion were (5.227, 1.450 and 1.083) respectively.

Conclusion and recommendations: Minia University Hospitals' doctors and nurses suffered from high sleep score more than clerks and it can be a source of stress and mental pressure for them and their families. Night shift work had a major effect on sleep disturbance. Hospitals authorities and policymakers with planning and implementing measures such as reducing the duration of shift-work schedules and execution of regular time management courses.
