689名医学生视疲劳发生现状及其影响因素分析

目的 了解锦州医科大学在读医学专业大学生视疲劳发生现状,并探讨其可能的影响因素。方法 采用随机抽样的方法,利用纸质问卷于2021年5月对该校医学生进行视觉疲劳情况调查,采用χ^(2)检验进行单因素分析,多因素分析采用logistic回归进行。结果 本次调查医学生689人,其中男生230人(33.38%),女生459人(66.62%)。医学生视疲劳量表得分M(P_(25)~P_(75))为18(12~24)分,视疲劳总体发生率为61.54%,女生(66.49%)高于男生(55.65%),差异有统计学意义(χ^(2)=5.054,P<0.05)。logistic回归分析显示,屈光不正(OR=1.875,95%CI:1.228~2.863)、工作学习时用眼姿势、眼与电脑距离、桌前使用手机姿势及时间均是视疲劳的影响因素(P<0.05)。结论视疲劳在医学生群体中普遍存在,及时矫正屈光不正,保持良好用眼习惯将可能起到预防和改善视疲劳的作用。

Analysis of occurrence and influencing factors of visual fatigue in 689 medical students

Objective To understand the current situation of visual fatigue among medical college students in Jinzhou Medical University and explore its possible influencing factors. Methods By using the method of random sampling, the paper questionnaire was used to investigate the visual fatigue of medical students in the school in May 2021. The χ2 test was used for univariate analysis, and the logistic regression was used for multivariate analysis. Results A total of 689 medical students were investigated, including 230 boys (33.38%) and 459 girls (66.62%). The score of M (P25 - P75) of visual fatigue scale of medical students was 18 (12 - 24), and the overall incidence of visual fatigue was 61.54%. The incidence of visual fatigue of the girls was 66.49%, higher than that of the boys (55.65%), and the difference was statistically significant (χ2=5.054, P<0.05). Logistic regression analysis showed that ametropia (OR=1.875, 95% CI: 1.228 - 2.863), eye posture during work and study, distance between eyes and computer, posture and time of using mobile phone in front of desk were the influencing factors of visual fatigue (P<0.05). Conclusion Visual fatigue is common in medical students. Timely correction of ametropia and maintaining good eye habits may play a role in preventing and improving visual fatigue.
