Association of sleep hygiene-related factors and sleep quality among university students in Hong Kong

Objective To examine whether sleep hygiene-related factors are associated with sleep quality among university students. Design Cross-sectional survey. Setting A university in Hong Kong. Participants Full-time university students recruited by convenience sampling. Main outcome measures Responses to a sleep questionnaire containing the Pittsburgh Sleep Quality Index and obtaining sleep hygiene knowledge and practice, as well as knowledge on caffeine were used for data collection. Results Regression analysis with stepwise selection procedure revealed that sleep hygiene practice was significantly associated with the Pittsburgh Sleep Quality Index score after adjusting for age, gender, year of study, and type of residence (b= -0.08, P<0.001). Conclusions Our study's results indicated that sleep hygiene practice was significantly associated with sleep quality. Appropriate measures and sleep hygiene education need to be emphasised among university students in order to increase their awareness on the importance of adopting healthy sleep hygiene practices.
