医学生睡眠质量影响因素分析

Sleep quality and its influencing factors in medical students

目的了解医学生睡眠质量影响因素,为改善医学生睡眠质量提供科学依据。方法采取多级随机整群抽样方法以878名医学生作为调查对象,采用匹兹堡睡眠质量批数(PSQI)进行调查,应用SPSS11.5软件进行统计分析。结果医学生PSQI平均分为(5.36±2.73)分,18.00%的学生睡眠质量差;学生不同性别、专业、上网时间、家庭人均月收入、体质指数(BMI)、吸烟状态、饮酒状态之间,睡眠质量差异无统计学意义(P>0.05);学生不同年级、学习时间、居住环境、锻炼等级之间,睡眠质量差异有统计学意义(P<0.05);多元逐步回归分析结果显示:年级、锻炼等级、饮酒、家庭人均月收入是睡眠质量的影响因素。结论医学生睡眠质量的影响因素较多,采取合理安排课程、改变不良生活习惯等方法,以改善医学生睡眠质量。

Objective To study the sleep quality and its influencing actors for improving sleep quality in medical students. Methods Totally 878 medical students were selected with multistage random cluster sampling. Pittsburgh Sleep Quality Index（PSQI） was used to evaluate the sleep quality and the results were analyzed with the SPSS 11.5 software. Resuits The mean PSQI score of medical students was 5.36 ± 2. 73.18.00% of the students were poor sleepers. No statistical significance was found between different gender, specialties, online time, monthly income per capita of the family, body mass index（ BMI）, smoking status, drinking status （P 〉 0. 05 ）. Statistical significance was found between different grades, study time,living environment,physical exercise（ P 〈 0. 05）. Rseults of multiple stepwise regression indicated that grade, physical exercise,drinking,monthly income per capita of the family were important influencing factors of PSQI. Conclusion Sleep quality was influenced by many factors. Measures such as arranging course reasonably, changing bad habit could be taken to improve sleep quality in medical students.
