高校医学生视频显示终端综合征与抑郁症状的关系

  目的  了解医学生视频显示终端(video display terminal, VDT)综合征现状，并探讨其与抑郁症状的相关性，为促进医学生心理健康提供依据。  方法  采用普查方法，于2019年11月对江西某大学医学部3 265名在校大一至大三学生进行问卷调查，收集个人基本情况、VDT综合征相关症状、抑郁状况等信息。  结果  高校医学生VDT综合征检出率为33.3%，不同性别、是否临床专业VDT综合征检出率差异均有统计学意义(χ2值分别为6.45，18.82，P值均 < 0.05)。抑郁症状检出率为54.6%，单因素分析显示，是否VDT综合征检出者抑郁症状检出率差异有统计学意义(χ2=63.88，P < 0.01)；多因素Logistic回归分析结果显示，VDT综合征可增加抑郁症状检出的风险(OR=1.84，95%CI=1.58~2.14，P < 0.01)。  结论  VDT综合征在医学生中检出率较高，且是医学生抑郁症状发生的相关因素。高校应重视对医学生合理使用视频终端的健康教育，并采取相应的措施加以干预，从而提高医学生身心健康水平。

Prevalence correlation of video display terminal syndrome and depression among medical students

  Objective  To investigate the prevalence of video display terminal syndrome (VDT) among medical students in university, and to explore the correlation between VDT syndrome and depressive symptoms, so as to provide theoretical guidance for promoting college students' mental health.  Methods  A total of 3 265 freshmen and juniors in the Department of Medicine of Nanchang University were surveyed with census method in November 2019 to collect information regarding general information, symptoms related to VDT syndrome, depression status.  Results  In the valid questionnaire, the detection rate of VDT syndrome among college students was 33.3%, and the detection rates of VDT syndrome varied significantly by sex and clinical major(χ2=6.45, 18.82, P < 0.05); The detection rate of depressive symptoms was 54.6%. One-way ANOVA showed that there was significant differences in VDT syndrome status between those with and without depression symptoms (χ2=63.88, P < 0.01). Multivariate Logistic regression showed that VDT syndrome could increase the risk of detecting depression (OR=1.84, 95%CI=1.58-2.14, P < 0.01).  Conclusion  VDT syndrome has a high detection rate in college medical students and is a risk factor for depression in medical students. Society and schools should pay attention to health education on the rational use of video terminals for medical students, and take corresponding measures to intervene, so as to improve the physical and mental health of medical students.
