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.
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.
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.
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.
关于中国大学生的睡眠时间与健康状况之间的关系知之甚少。本研究探讨了中国大学生的睡眠时间与自我报告健康之间的关系。
共招募了 2312 名受试者（澳门 928 名、香港 446 名、中国大陆 938 名）。对睡眠和自我报告的健康进行了标准化测量。睡眠时间分为以下几类：<6 小时/天、6-<7 小时/天、7-9 小时/天和>9 小时/天。
总体而言，71%的大学生报告健康状况不佳，53%的大学生睡眠时间为 7-9 小时/天，14%的大学生睡眠时间少于 6 小时/天，32%的大学生睡眠时间为 6-<7 小时/天，1%的大学生睡眠时间大于 9 小时/天。单因素分析显示，与睡眠时间适中（7-9 小时/天）的学生相比，睡眠时间较短（<6 小时/天和 6-<7 小时/天）的学生更有可能报告健康状况不佳。多变量逻辑回归分析发现，在校正年龄、性别、体重指数、大学所在地、是否独生子女、宗教信仰、对专业的兴趣、学业压力、护理专业、对未来的悲观态度和抑郁等因素后，睡眠时间少于 6 小时/天（比值比 1.98，95%置信区间 1.34-2.92，p<0.01）与自我报告的健康状况不佳显著相关。
中国大学生健康状况不佳较为普遍，且似乎与睡眠时间短密切相关。进一步的纵向研究有助于更好地理解大学生睡眠模式和健康状况之间的相互作用。
