Sleep problems among university students are common; however, the association between many sleep-related factors and sleep behaviors is still unclear. The purpose of this study is to examine different sleep behaviors and sleep-related factors influencing such behaviors in university students. A descriptive survey was conducted on 400 university students in Hong Kong. The instruments for data collection consisted of the Pittsburgh Sleep Quality Index (PSQI), a sleep hygiene practice questionnaire, demographic data, and other sleep-related factors. The results reveal that 57.5% of the 400 university students are poor sleepers. Sex, year of study, sleep hygiene practice, and perceived adequate sleep in the past month all demonstrate significant associations with poor sleepers. A high prevalence of sleep-related problems among college students is confirmed and associated factors are identified. Students should be encouraged to follow sleep hygiene practice, adequate time management for academic and social activities, and suitable stress-relieving measures.
