摘要
目的了解深圳市龙岗区初中生视力及屈光状态,为近视防控提供科学依据。方法整群抽取2015年1-12月深圳市龙岗区3所不同中学共1 925例在校学生进行问卷调查,同时进行视力、眼前节、眼底、眼位和屈光状态检查,分析视力不良的危险因素,并对不同性别和年级的屈光状态进行比较。结果深圳市龙岗区1 925例初中生视力不良检出率为70.5%,其中性别女、高度近视家族史,连续看近时间过长为中学生视力不良的危险因素。随着年级增长,正视、远视、散光的检出率逐渐减小,且正视组(χ~2=22.153,P<0.05)和远视组(χ~2=7.601,P<0.05)各年级比较差异有统计学意义;轻度近视、中度近视、高度近视的检出率逐渐增多,且轻度近视组(χ~2=8.508,P<0.05)和高度近视组(χ~2=27.934,P<0.05)各年级比较差异有统计学意义。结论深圳市龙岗区初中生视力不良检出率高,近视是主要原因,做好近视防治工作对控制中学生视力不良有重要意义。
Objective To investigate visual acuity and refractive status of junior school students in Longgang District of Shenzhen city,provide scientific basis for prevention and control of myopia.Methods A total of 1 925 students were selected from three junior schools in Longgang District of Shenzhen city from January to December in 2015 by cluster sampling method,then a questionnaire survey was performed.Visual acuity,anterior segment,fundus,eye position,and refractive status were examined in all the students.The risk factors of poor visual acuity were analyzed.The refractive statuses of these students of different grades and genders were compared.Results The detection rate of poor vision was 70.5% among 1 925 junior school students in Longgang District of Shenzhen city.Female,family history of high myopia,using eyes for a long time and at close range were the main risk factors.The detection rates of emmetropia,hyperopia,and astigmatism decreased gradually with the increase of grade,there were statistically significant differences in the detection rates of emmetropia and hyperopia among the students in different grades （X^2 =22.153,P〈0.05;X^2 =7.601,P〈0.05）.The detection rates of mild,moderate,and high myopia increased gradually with the increase of grade,there were statistically significant differences in the detection rates of mild and high myopia among the students in different grades （X^2 =8.508,P〈0.05;X^2 =27.934,P〈0.05）.Conclusion The detection rate of poor vision is high among the junior school students in Longgang District of Shenzhen city.Prevention and treatment of myopia is of great importance in controlling poor vision among junior school students.
