【摘要】：目的了解紹興市7~15歲中小學(xué)生近視狀況,為制定干預(yù)措施提供科學(xué)依據(jù)。方法采用分層整群抽樣方法,選取紹興市4所小學(xué)和4所中學(xué)共2 911名學(xué)生采用室內(nèi)燈箱式標(biāo)準(zhǔn)對(duì)數(shù)視力表測(cè)量雙眼視力,裸眼視力≤4.9為視力不良;然后用1%阿托品進(jìn)行散瞳檢影驗(yàn)光,屈光范圍0.5 D為近視進(jìn)行視力檢測(cè)。使用統(tǒng)計(jì)方法主要有χ2檢驗(yàn)、t檢驗(yàn)、方差分析等。結(jié)果小學(xué)生近視檢出率(25.1%)低于初中生(72.8%)(χ2=592.626,P0.01);小學(xué)生近視平均度數(shù)為(213.88±105.98),中學(xué)生近視平均度數(shù)為(305.44±165.23),差異有統(tǒng)計(jì)學(xué)意義(t=-8.057,P0.01)。近視檢出率和近視度數(shù)隨著年級(jí)遞增而升高(χ2/F值分別為667.195,10.753,P值均0.01),城市學(xué)生近視率高于農(nóng)村學(xué)生(χ2=42.224,P0.01),重點(diǎn)學(xué)校學(xué)生近視率高于一般學(xué)校(χ2=6.224,P0.05)。結(jié)論紹興市中小學(xué)生近視狀況不容樂(lè)觀(guān)。應(yīng)加大近視高發(fā)態(tài)勢(shì)的干預(yù)力度,培養(yǎng)健康和科學(xué)的用眼習(xí)慣。
[Abstract]:Objective to investigate the myopic status of 7-15-year-old primary and middle school students in Shaoxing city, and to provide scientific basis for making intervention measures. Methods using stratified cluster sampling method, 2 911 students from 4 primary schools and 4 middle schools in Shaoxing city were selected to measure binocular visual acuity by indoor lamp box standard logarithmic visual acuity meter. The visual acuity of naked eyes 鈮，
