Abstract : Background: Sleep is a fundamental physiological process essential for cognitive performance, emotional regulation, and overall health. Among college students, sleep disturbances are increasingly prevalent and have been associated with poor academic outcomes and reduced quality of life. Lifestyle factors, including physical inactivity, excessive screen time, and sedentary behaviour, are hypothesised to adversely affect sleep quality.  Aim: To estimate the prevalence of poor sleep quality among college students and evaluate the influence of lifestyle factors — particularly physical activity and screen time — on sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and the Global Physical Activity Questionnaire (GPAQ).

Keywords : Sleep Quality, PSQI, GPAQ, Physical Activity, College Students, Sedentary Behaviour, Screen Time, Cross-Sectional Study.
