中国八所中医药高校大学生睡眠状况调查

目的 调查中医药高校大学生的睡眠状况，分析可能的影响因素。方法 采用分层整群抽样法从国内四个区域8所中医药高校，获取7 142名大学生为研究对象，采用匹兹堡睡眠质量指数（Pittsburgh sleep quality index，PSQI）和自行设计的问卷进行调查。结果 共收回有效问卷6 534份，男生有1 778（27.21%）人，女生有4 756（72.79%）人；平均年龄为（20.32±1.23）岁。PSQI平均得分为（4.58±2.30）分，睡眠差（PSQI ≥ 8）的检出率为10.33%。城市生源学生的PSQI得分（4.36±2.32）优于乡镇（4.64±2.29），差异有统计学意义（t=-3.909，P<0.001），外向型（4.50±2.38）和中间型（4.54±2.25）性格的学生PSQI得分优于内向型（4.78±2.35），差异有统计学意义（F=6.481，P=0.002），体质指数正常者的PSQI得分（4.52±2.22）优于低体重者（4.64±2.38）、超重者（4.89±2.60）和肥胖者（5.03±2.60），差异有统计学意义（F=5.892，P=0.001）；性别间PSQI得分差异无统计学意义（t=-0.005，P=0.996）。多因素回归分析发现，日常压力数、生活满意度、规律饮食等12个因素可能影响了大学生的睡眠状况。结论 我国中医药高校大学生睡眠质量的影响因素多，睡眠质量存在进一步提升的空间。

A survey of sleep quality among college students from eight universities of Chinese medicine in China

Objective To investigate the sleep quality of college students from eight universities of Chinese medicine and analyze the possible influencing factors. Methods A stratified cluster sampling method was used to obtain 7 142 college students from 8 universities of traditional Chinese medicine in four regions of China. The Pittsburgh sleep quality index (PSQI) and a self-designed questionnaire were used to carry out a cross-sectional survey. Results Totally 6 534 valid questionnaires were retrieved, boys 1 778 (27.21%), girls 4 756 (72.79%); the mean age was (20.32±1.23) years. The mean score of PSQI was (4.58±2.30), detection rate of insomnia (PSQI ≥ 8) was 10.33%. The score of PSQI of students from cities (4.36±2.32) was better than those from villages and towns (4.64±2.29, t=-3.909, P<0.001). The score of PSQI of students who belonged to extroversion (4.50±2.38) and intermedius type (4.54±2.25) was better than those who belonged to introversion (4.78±2.35, F=6.481, P=0.002). The score of PSQI of students with normal weight(4.52±2.22) was better than those who were underweight (4.64±2.38), overweight (4.89±2.60) or obesity (5.03±2.60, F=5.892, P=0.001). There was no significant difference in PSQI score between different genders(t=-0.005, P=0.996). Multiple regression analysis showed that there were twelve factors which may influence college students' sleep quality like index of pressure, life satisfaction and regular dietary. Conclusions The sleep quality of students from universities of Chinese medicine which was influenced by many factors still needs to be further improved.
