摘要:
目的 了解河南省四至六年级小学生视力不良、配镜和屈光检查情况,为对学生视力采取精准干预措施和准确评估提供科学依据。 方法 采用分层整群随机抽样方法,抽取河南省17个省辖市29 187名四至六年级学生进行远视力检查和问卷调查。 结果 四至六年级学生总视力不良检出率为63.6%,女生(69.0%)高于男生(59.0%),城区学生(65.3%)高于郊县学生(62.5%)(χ2值分别为312.6,23.6,P值均 < 0.01);重度视力不良检出率为28.5%;随着年级的升高,视力不良和重度视力不良检出率呈上升趋势(χ趋势2值分别为278.7,775.4,P值均 < 0.01)。13.2%的学生过去1年内没有做过视力检查;视力不良学生戴镜率为27.0%,单眼视力不良学生戴镜率为3.2%;46.8%的戴镜学生配镜前接受了散瞳验光。 结论 河南省四到六年级学生视力不良问题突出,需要加强视力监测和眼健康教育工作。 Abstract:Objective To analyze the prevalence of poor vision and eyeglass prescription, refractive examination among primary school students of grade 4-6 in Henan, so as to provide scientific basis for precise interventions for student vision health. Methods A stratified cluster random sampling method was used to investigate a total of 29 187 students of grade 4-6 from 17 cities in Henan Province. Distant vision examination and questionnaire survey were conducted. Results The overall prevalence of poor vision for grade 4-6 students in Henan was 63.6%, with girls (69.0%) higher than boys (59.0%), urban students (65.3%) higher than suburban students (62.5%)(χ2=312.6, 23.6, P < 0.01). The prevalence of severe poor vision was 28.5%.With the increase of grade, the detection rate of poor vision and severe poor vision increased(χtrend2=278.7, 775.4, P < 0.01). Totally 13.2% of pupil did not have a visual examination in the past year. The rate of wearing glasses was 27.0% for students with poor eyesight and 3.2% for students with poor monocular eyesight. Totally 46.8% of the students wearing glasses received mydriatic optometry before wearing glasses. Conclusion The problem of poor vision among students of grade 4-6 in Henan is prominent, so it is necessary to strengthen eyesight monitoring and eye health education. -
