Sleep Disturbance and Daytime Sleepiness among Undergraduate Medical Students in Islamabad: A Single-Institution Cross-Sectional Study
Abstract
Objective: To determine the prevalence of poor sleep quality and daytime sleepiness among undergraduatemedical students and to explore the association between the two scores. Additionally, to compare the sleepquality and daytime sleepiness across gender and academic levels, and identify key factors associated withpoor sleep quality and daytime sleepiness, including BMI, screen time, smoking, and exercise.Study Design: Cross-sectional study.Place and Duration of Study: The study was conducted at the Department of Community Medicine, HBSMedical and Dental College, Islamabad, Pakistan from 26th April 2024 to 30th January 2025.Methods: A total of 330 undergraduate students were included in the study. A stratified random samplingtechnique was employed. The data collection in this study consisted of a questionnaire developed through acomprehensive review of relevant literature. The initial pool of items was derived by examining widely citedtheoretical frameworks and empirical studies on sleep disturbances and sleep quality. The questionnaireunderwent an expert review, and a pilot test was subsequently conducted with a sample of 20 participants torefine the wording, assess item clarity, and determine internal consistency. Data were collected through a selfadministeredquestionnaire in English, which was entered, managed, and analyzed using SPSS version 25.Results: Among 330 undergraduate medical students, 64.2% were females, and the mean age was 21.47±1.776years. The majority of…
