Sleep problems are related to increased health concerns, irritability, depression, fatigue, attention and concentration difficulties, along with poor academic performance. The aim of this paper is to conduct a survey based on a questionnaire that would characterize the quality of sleep in students living in dormitories of Tehran University of Medical Sciences (TUMS). Methods: We conducted a cross-sectional study using the stratified random sampling approach on 277 students residing in dormitories in Tehran. A demographic questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used for data collection. Results: Mean (CI) of PSQI in students was 8.57 (8.10-9.04). Using the cut-off score of 6 for the PSQI global score, 73.3% (68.1%-78.5%) of students were described as poor sleeper. Female students had a worse quality of sleep compared to male. The mean duration of sleep in students was 5:15 ± 105 (hours). This was significantly higher in male students than female students. There were no significant relationships between demographic variables such as; age, academic level, marital status and family income with and quality of sleep. Conclusion: This study showed that poor sleep quality is prevalent among students living in dormitories of TUMS. Therefore it is necessary to provide effective educational interventions for this group in order to improve the quality of sleep. Keywords: Sleep Quality, Dormitory, Pittsburgh
