Sleep duration and self-rated health in Chinese university students.
PURPOSELittle 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.
METHODSAltogether, 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.
RESULTSOverall, 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.
CONCLUSIONSPoor 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.
