摘要 目的 调查分析青岛市某重点高中学生视力状况,为高中生近视防治工作提供参考依据。方法 于青岛市某重点高中随机抽取一、二、三年级在校学生共600名,采用调查问卷的方式对近视相关的18项内容进行调查,共获得有效问卷472份,对数据资料进行统计分析。结果 调查的472名学生中,高中一、二、三年级学生的近视率分别为81.41%(127/156)、84.56%(115/136)和90.00%(162/180);男生和女生的近视率分别为79.62%(168/211)和90.42%(236/261),女生的近视率明显高于男生(χ2=11.03,P<0.05)。各年级近视学生的近视程度比较差异无显著性(P>0.05)。3个年级选择从小学开始近视者平均占45.60%。近视原因调查显示,用眼距离小于30cm、看电视或手机时间过长、连续学习时间过长(大于200min)及户外活动时间短(有效时长小于1h)均是3个年级学生近视的共同主要原因(P>0.05)。不同年级学生在规范用眼卫生、增加体育活动时间及减少持续用眼时间方面差异有显著性(χ2=12.00~48.25,P<0.01)。结论 高中生近视患病率较高,主要始发于小学阶段,高中近视加重主要是由于缺乏视力保护意识、用眼习惯不良和课业负担增加等原因,应家校联合积极给予防治干预。 Objective To investigate and analyze the status of vision among students in a key high school,and to provide a reference for the prevention and treatment of myopia in high school students.Methods A total of 600tenth-,eleventh-,and twelfth-grade students were selected from a key high school in Qingdao and a questionnaire survey was conducted to investigate 18 items associated with myopia.A total of 472valid questionnaires were obtained,and a statistical analysis was performed for data.Results The myopia rate was 81.41%(127/156)in the tenth grade,84.56%(115/136)in the eleventh grade,and 90.00%(162/180)in the twelfth grade.The myopia rate was 90.42%(236/261)in girls and 79.62%(168/211)in boys,and girls had a significantly higher myopia rate than boys(χ2=11.03,P<0.05).There was no significant difference in the degree of myopia between the students with myopia at different grades(P>0.05).Of all students,45.6%had myopia in primary school.As for the cause of myopia,close eye-using distance(<30cm),a long time spent watching computer or mobile phone,a long time of continuous reading(>200min),and a short time of outdoor activities(<1h)were the common causes of myopia in the three grades(P>0.05).There were significant differences between the three grades in standardizing eye hygiene,increasing the time of physical activity,and reducing the time of continuous eye use(χ2=12.00-48.25,P<0.01).Conclusion There is a high prevalence rate of myopia in high school students,and most of them develop myopia in primary school.A lack of vision protection,poor eye-using habits,and increased schoolwork burden are the main causes of aggravation of myopia in high school.Necessary measures should be taken for prevention and treatment in school and at home.
