摘要
目的了解上海市中小学生视疲劳流行现状及与多媒体教学环境的关联,为制定干预策略提供参考。方法采取方便整群抽样方法抽取上海市5个区15所学校小学四年级、初二和高一年级的2 811名学生,采用自填问卷方法调查学生近4周内视疲劳发生情况及多媒体教学环境现状。结果视疲劳症状阳性发生率为17.1%,其发生率随年级增加而增加（χ2趋势=8.316,P〈0.01）,性别差异无统计学意义（χ2=0.075,P〉0.05）。多因素Logistic回归结果显示,反映多媒体教学环境的学生就坐位置和是否来得及记录笔记与视疲劳的发生有关,表现为就坐于边侧的学生位置和来不及或不记笔记是视疲劳发生的独立危险因素,其OR值（95%CI）分别为1.69（1.08~2.64）和1.52（1.17~1.97）。结论上海市中小学生视疲劳现状不容乐观,在教学过程应注意多媒体教学环境对其影响并采取针对性的措施。
Objective To explore and analyze the epidemiological characteristics and related factors of primary and middle school students in Shanghai and to provide suggestions for taking appropriate preventive measures. Methods Convenience sampling was used to select 2 811 primary and middle school students of 15 schools of 5 regions in Shanghai. Self-administered questionnaires were used to survey symptoms of visual fatigue and related factors such as vision, self-evaluation of pressure and study, multimediaaided teaching environment and dietary habit. Results The percentage of visual fatigue was 17.1%, growing as the grade increased. There was no statistical difference in sex. By using muhiple logistic regression, we got the conclusion that visual fatigue was associated with students who were seated near the window and door sides with the rows （ OR = 1.69 ; 95%C1= 1.08- 2.64） and ＂unable to take notes＂ （ OR= 1.52, 95%CI= 1.17- 1.97} ,respectively. Conclusion Current situation of vision fatigue of primary and middle school students of Shanghai is far from optimistic ,which was the result of muhiple factors. We need to use appropriate measures and don＇ t ignore the effect of multimedia-aided teaching environment.
