摘　　要：目的探讨广东省广州市在校大学生睡眠质量与压力的相关性,确定与睡眠质量密切相关的压力因素,为制定针对性干预措施提供依据。方法采用分层整群抽样方法,抽取来自广州市6所综合院校的1 296名在校大学生,采用匹兹堡睡眠质量指数量表(PSQI)评估睡眠质量,采用大学生压力量表评估压力状况,采用SPSS13.0统计软件对资料进行典型相关分析。结果大学生压力总分为(34.19±17.92)分,其中,个人烦扰因子得分最高,为(16.01±9.63)分;PSQI总分为(6.04±3.33)分,睡眠问题(PSQI得分≥8分)检出率为28.4%;睡眠质量与压力第1、2对典型变量的相关性均有统计学意义(P<0.001),第1、2对典型变量的相关系数分别为0.380、0.244,而前2对典型变量累积贡献率达98.150%;在第1典型变量中,睡眠效率、睡眠障碍与个人烦扰相关,在第2典型变量中,催眠药物、日间功能障碍与学习烦扰、个人烦扰相关。结论广州市大学生的压力状况对其睡眠效率、睡眠障碍、日间功能障碍以及催眠药物使用情况有明显影响,而学习烦扰、个人烦扰是主要相关因素。Objective To explore the association between sleep quality and stress among college students, and to de- termine factors of pressure correlated most closely with sleep quality. Methods College students from 6 universities in Guangzhou city were selected with duster sampling method. The sleep quality was evaluated with Pittsburgh Sleep Quality Index （PSQI）and the college students＇ stress scale was used for the assessment of pressure condition. The data were analyzed with canonical correlation analysis by Statistical Package for Social Sciences （SPSS）. Results Totally 1 400 questionnaires were distributed and l 296 qualified questionnaires were collected with an efficiency of 92. 6%. Survey re- sults showed that the total stress score was 34. 19 ±17. 92 and the score of individual annoyance was the highest（ 16. 01 ±9.63） among the students. For the students, the PSQI score was 6. 04 ±3.33 and the overall prevalence of sleep disturb- ances （PSQI score ≥ 8 ） was 28. 4% （368/1 296 ）, with a significant canonical correlation. The canonical correlation coef- ficient of the two pairs of canonical variables were 0. 380 and 0. 244, respectively, and the cumulative proportion of the first two pairs of canonical variables was above 0. 98. For the first pair of canonical variables, the contribution of sleep ef- ficiency, sleep disorders and individual pressure were higher, while for the second pair, hypnotic drugs, daytime dysfunc- tion and study stress, and individual pressure were the most important factors. Conclusion Stress status has obvious effect on sleep quality, sleep disorder, daytime dysfunction, and hapnotic drug use and the stress on study and individual annoyance contribute mainly to sleep quality among college students in Guangzhou city.
