【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,P0.01),性别差异无统计学意义(χ2=0.075,P0.05)。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。
[Abstract]:Objective to investigate the prevalence of visual fatigue among primary and middle school students in Shanghai and its relationship with multimedia teaching environment, and to provide reference for formulating intervention strategies. Methods A convenient cluster sampling method was used to select 2 811 students in grade four, grade two and grade one of 15 primary schools in 5 districts of Shanghai. A self-filled questionnaire was used to investigate the occurrence of visual fatigue and the current situation of multimedia teaching environment in the past 4 weeks. Results the incidence of visual fatigue symptoms was 17.1g, and the incidence increased with the increase of grade (蠂 ~ 2 trend: 8.316g / P 0.01). There was no significant difference in sex (蠂 ~ 2 = 0.075) (蠂 ~ 2 = 0.075). The results of multi-factor Logistic regression showed that the students who reflected the multimedia teaching environment were related to the occurrence of visual fatigue in terms of sitting position and whether they had time to record notes. The independent risk factors of visual fatigue were the position of students sitting on the side and not taking notes, the OR value of which was 1.691.08 / 2.64 (OR = 1.62) and 1.171.97 / s, respectively. The risk factors of visual fatigue were as follows: (1) the odds ratio (OR) was 1.691.08 (2.64) and 1.52 (1.17) / 1.97 (respectively). Conclusion the current situation of visual fatigue of primary and middle school students in Shanghai is not optimistic. In the teaching process, we should pay attention to the influence of multimedia teaching environment on it and take targeted measures.
