Abstract

Purpose: Little is known about the association between sleep duration and health status in Chinese university students. This study examined the association between sleep duration and self-rated health in university students in China. Methods: Altogether, 2312 subjects (928 in Macao, 446 in Hong Kong, and 938 in mainland China) were recruited. Standardized measures of sleep and self-reported health were administered. Sleep duration was categorized in the following way: < 6 h/day, 6 to < 7 h/day, 7–9 h/day, and > 9 h/day. Results: Overall, 71% of university students reported poor health, 53% slept 7–9 h/day, 14% slept less than 6 h/day, 32% slept 6 to < 7 h/day, and 1% slept > 9 h/day. Univariate analysis revealed that compared to students with medium sleep duration (7–9 h/day), those with short sleep duration (< 6 h/day and 6 to < 7 h/day) were more likely to report poor health. Multivariate logistic regression analysis found that after controlling for age, gender, body mass index, university location, being a single child, religious beliefs, interest in academic major, academic pressure, nursing major, pessimism about the future, and depression, sleep duration of less than 6 h/day (odds ratio (OR) 1.98, 95% confidence interval (CI) 1.34–2.92, p < 0.01) was independently and significantly associated with poor self-reported health. Conclusions: Poor health status is common in Chinese university students, which appears to be closely associated with short sleep duration. Further longitudinal studies are warranted to gain a better understanding of the interaction between sleep patterns and health status in university students.
