Abstract

Background & Objectives: Sleep quality is an important factor in student life and affects in their learning process. 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.

Abstract
Background and Objectives: Frailty syndrome significantly impacts the health of older adults, and sleep quality is likely a pertinent clinical factor. Therefore, this study aims to investigate the relationship between sleep quality and sleep duration with frailty syndrome in the older adults of Naqadeh City.
Methods: This cross-sectional study enrolled 347 older adults aged 60 years and above in Naqadeh city in 2020 using 2-stage sampling (first, stratified, and then simple random sampling. Data collection tools included demographic questionnaires, the Edmonton Frail Scale, and the Pittsburgh Sleep Quality Index. Statistical analysis was performed using SPSS25 software.
Results: The study revealed that 30.3% of older adults were frail. Furthermore, a statistically significant correlation was observed between sleep quality and duration with older adults' frailty (r=0.635, p<0.001 and r=-0.170, p<0.001, respectively). Additionally, all frailty domains exhibited a significant relationship with sleep quality, with the most notable associations found in mood, medication use, and cognition domains (r = 0.487, r = 0.397, r = 0.381, respectively).
Conclusion: Probably, the quality and duration of sleep affect the frailty syndrome, so it is necessary to design and implement effective interventions to improve the quality of sleep and ultimately reduce the frailty of older adults, especially in the domains of cognition and mood.
