Abstract

UNLABELLED

The objective of the study was to analyze associations among quality of sleep, profile of the studies, and lifestyle factors among the students of three different study profiles (medicine, economics, and law).

MATERIAL AND METHODS

A total of 405 randomly selected students from the first and fourth years of studies from 4 different universities in Lithuania answered the standardized questionnaires consisting of two parts: 1) the Pittsburgh Sleep Quality Index (PSQI) for subjective evaluation of sleep quality; 2) the questionnaire about sleep and lifestyle habits and impact of poor sleep on the quality of life developed by the researchers.

RESULTS

More than half (59.4%) of the students scored higher than 5 on the PSQI, which allowed suspecting sleep disorders. A significant difference in the frequency of poor sleepers was found regarding the profile of studies (P<0.05) showing the highest frequency of sleep disturbances among medical students. There was a significant correlation between quality of sleep and subjective evaluation of quality of life (P<0.01). Medical students experienced the highest impact of poor sleep on the quality of life (P=0.008). Students studying before going to sleep, spending more time studying, and having less leisure time had worse quality of sleep (P<0.01). A significant difference was found among three profiles of studies regarding the anxiety about studies (P<0.0005) and subjective estimation of success in studies (χ²=27.9, P<0.0005), showing the highest anxiety and worst satisfaction among students of medicine.

CONCLUSIONS

The incidence of sleep problems is high among students in Lithuania, reaching 59.4%. Medical students have worse quality of sleep and worse impact of poor sleep on the quality of life compared to students of law and economics. A significant difference was found between medical students and their peers in other profiles of studies regarding their attitudes and habits related to studies: medical students spent more time for studying, were more anxious about studies and less satisfied with the results, studied more often before going to sleep.

摘要

目的

分析三种不同学习类型（医学、经济和法律）的学生睡眠质量、研究概况和生活方式因素之间的关系。

材料和方法

从立陶宛四所大学的一、四年级中随机抽取 405 名学生，填写标准化问卷，问卷包括两部分：1）匹兹堡睡眠质量指数（PSQI），用于主观评估睡眠质量；2）由研究人员开发的关于睡眠和生活方式习惯以及睡眠质量差对生活质量影响的问卷。

结果

超过一半（59.4%）的学生 PSQI 得分高于 5，这表明可能存在睡眠障碍。学习类型不同，睡眠质量差的频率也存在显著差异（P<0.05），医学专业学生睡眠障碍发生率最高。睡眠质量与生活质量主观评价之间存在显著相关性（P<0.01）。医学专业学生睡眠质量差对生活质量的影响最大（P=0.008）。睡前学习、学习时间长、休闲时间少的学生睡眠质量较差（P<0.01）。三种学习类型的学生在学习焦虑（P<0.0005）和对学习成功的主观评估（χ²=27.9，P<0.0005）方面存在显著差异，表明医学专业学生的焦虑最高，对学习的满意度最差。
