摘要
目的调查了解昆明市中小学生视力低下现状及其可能的影响因素,为制订近视预防措施提供依据。方法对昆明市某社区1 366例中小学生进行视力检查和问卷调查,利用χ2和Logistic回归进行视力低下单因素和多因素分析。结果昆明市某社区中小学生视力低下检出率为57.5%,中学生显著高于小学生(70.7%vs.46.4%,χ2=81.966,P=0.000)。多因素Logistic回归分析显示用眼习惯不良(OR=3.176)、坐姿不良(OR=2.844)、连续学习时间大于或等于2h/d(OR=1.743)、课间行为不良(OR=1.952)、荧屏接触时间大于或等于2h/d(OR=1.660)和做课外作业时间大于或等于2h/d(OR=1.535)均为导致中小学生视力低下的危险因素,而户外活动时间大于或等于2h/d(OR=0.059)为保护因素。结论中小学生视力低下检出率较高,养成良好的用眼习惯、减轻学业负担、减少荧屏接触时间、保证户外活动时间和睡眠时间将有助于保护中小学生视力。
Objective To understand the status quo of low vision and the potential influential factors among primary and second-ary school students in Kunming .Methods The visual activity test and the questionnaire survey were performed among 1 366 prima-ry and secondary school students in a community of Kunming ,χ2 and the multivariate Logistic regression were adopted to perform the single factor and multifactor analysis .Results The detection rate of low vision in this community was 57 .5% ,which of the sec-ondary school students was higher than that of primary school students （70 .7% vs .46 .4% ,χ2 =81 .966 ,P=0 .000） .The multifac-tor Logistic regression analysis showed the bad habit of using eyes （OR=3 .176） ,poor posture（OR=2 .844） ,continuous learning time ≥2 h per day（OR=1 .743） ,break bad behavior（OR=1 .952） ,the screen contact time ≥2 h per day（OR=1 .660） and continu-ous doing homework time ≥ 2 h per day（OR=1 .535） were the risk factors leading to the low vision ;while the outdoor activities time ≥ 2 h per day（OR=0 .059） were the protective factors .Conclusion The detection rate of low vision among primary and mid-dle school students in Kunming is higher .Cultivating the good habits using eyes ,alleviating the study load ,reducing the screen con-tact time ,and ensuring the time of outdoor activities and sleep time will conduce to protect the eyesight of primary and secondary school students .
