Abstract

University students often experience poor sleep quality due to various academic and lifestyle pressures. This study analyzes a dataset of 500 university students to identify key determinants of sleep quality. This paper examines demographic factors (age, gender, year of study), daily habits (study hours, screen time, caffeine intake, physical activity), and sleep characteristics (sleep duration, bed/wake times). Multiple linear regression and random forest models were used to explore linear and non-linear relationships. The linear regression models showed very low explanatory power in both the full dataset (n = 500) and a filtered dataset (n = 52), suggesting that none of the measured factors had a significant linear impact. The random forest models performed well on the training set but had poor performance on the test set, indicating possible overfitting. However, both models consistently highlighted sleep duration and study hours as relatively important features. These findings imply that unmeasured factors, such as psychological stress, may play a larger role in students’ sleep quality. In conclusion, while lifestyle and demographic variables alone did not strongly predict sleep quality in this sample, the results highlight the need to consider psychological and environmental factors. This paper discusses the implications, limitations (including the lack of psychological/cultural variables and seasonal effects), and provide suggestions for future research and interventions to improve student sleep health.
