Objectives: Sleep quality influences health, memory and learning, but it’s impact on cognitive performance remains unclear, with the studies showing mixed results. Exploring the determinants of sleep quality and their potential links with cognition can provide insight into student well-being and informed strategies to improve academic and mental health outcomesSleep quality influences health, memory and learning, but it’s impact on cognitive performance remains unclear, with the studies showing mixed results. Exploring the determinants of sleep quality and their potential links with cognition can provide insight into student well-being and informed strategies to improve academic and mental health outcomes. So, the objectives of the study are to assess the prevalence and determinants of poor sleep quality and its association with cognitive functioning among undergraduate students. Materials and Methods: A cross-sectional study was conducted among undergraduates of The Apollo University, Chittoor. Participants completed the Pittsburgh Sleep Quality Index (PSQI) for sleep quality, the Sleep Hygiene Index for contributing factors, and the Montreal Cognitive Assessment for cognitive performance. Results: Among 610 participants, 352 (57.7 %) had poor sleep quality (PSQI > 5). Significant determinants included staying in bed longer than necessary ( P = 0.017); going to bed angry, nervous, or upset ( P < 0.001); an uncomfortable bed ( P < 0.001); room discomfort from temperature, noise, or light ( P < 0.001); and thinking or worrying in bed ( P < 0.001). Kendall’s tau-b showed that poorer sleep hygiene was weakly associated with lower cognitive scores and worse sleep quality, while cognitive function itself showed no significant correlation with sleep quality. Conclusion: Over half of undergraduates reported poor sleep quality, largely linked to modifiable behavioral and environmental factors. Promoting regular sleep patterns, stress control, and sleep hygiene education could improve sleep quality and cognitive outcomes.
