摘　　要：目的 了解2019年天津市中小学生视屏行为对视力不良的影响,为学生视力不良的防控工作提供参考依据。方法 于2019年9月,采用分层整群抽样方法,抽取天津市23 477名9~18岁中小学生为调查对象进行视力检查和问卷调查,分析视屏时间和视屏时近距离用眼对视力不良的影响。采用SPSS 26.0统计软件进行χ^(2)检验、趋势χ^(2)检验和多因素logistic回归分析。结果 2019年天津市中小学生视力不良检出率为76.5%,其中女生(80.7%)高于男生(72.6%),住校生(85.9%)高于非住校生(75.7%),城区学生(78.8%)高于郊区学生(74.3%),差异均有统计学意义(P<0.01)。小学、初中、职业高中和普通高中的视力不良率呈上升趋势(χ^(2)趋势=1 094.032,P<0.01)。多因素logistic回归分析结果显示,调整年级、性别、地区后,1周内每天使用移动电子设备时间(与未使用相比,使用0.5~<1 h学生OR=1.253,95%CI:1.132~1.386;使用≥1 h学生OR=1.088,95%CI:1.001~1.182)、经常或总是躺着或趴着看书或电子屏幕(OR=1.154,95%CI:1.058~1.259)与中小学生视力不良高风险相关(P<0.05,P<0.01);1周内每天看电视时间(与未使用相比,看电视<1 h学生OR=0.802,95%CI:0.734~0.877;看电视1~<2 h学生OR=0.796,95%CI:0.718~0.882;看电视≥2 h学生OR=0.738,95%CI:0.658~0.827)与中小学生视力不良低风险相关(P<0.01)。结论 天津市中小学生视力不良现状不容乐观,不良视屏行为与视力不良相关,家长和老师应加强对学生电子产品使用的监管。Objective To understand the harmful effects of electronic screen on eyesight of primary and secondary school students in Tianjin in 2019,and provide the reference for the prevention and control of poor eyesight of students. Methods In September2019,the stratified cluster sampling method was used to select 23 447 students(9-18 years old) from Tianjin as the subjects. The investigation was performed with questionnaire and eyesight examination to analyze the harmful effects of electronic screen on eyesight. The χ2test,trend χ2test and multiple factor logistic regression were used to analyze the data. The used software was SPSS26.0. Results In 2019,the detection rate of poor vision among primary and secondary school students in Tianjin was 76.5%(females:80.7% > males:72.6%),the detection rate(85.9%) of poor vision among residential students were significantly higher than that(75.7%) among the non-residential students,and the detection rate(78.8%) of poor vision in urban students were significantly higher than that(74.3%) in suburban students(P<0.01). The poor vision rates in students of primary school,secondary school,vocational high school and general high school showed upward trend (χ2trend=1 094.032,P<0.01). The multiple factor logistic regression analysis showed that after adjusting grade,gender and area,the time of using mobile electronic devices every day within one week(compared with no use,students using 0.5-<1 h OR=1.253,95%CI:1.132-1.386,students using ≥1 h OR=1.088,95%CI:1.001-1.182),often or always reading books or electronic screens when lying or lying down(OR=1.154,95%CI:1.058-1.259) were related to the high risk for poor eyesight(P<0.05 or P<0.01);the time of watching TV every day within one week(compared with no use,students using <1 h OR=0.802,95%CI:0.734-0.877,students using 1-<2 h OR=0.796,95%CI:0.718-0.882,students using ≥2 h OR=0.738,95%CI :0.658-0.827) was related to low risk for poor eyesight(P<0.01).Conclusion The unhealthy video behaviors of primary and secondary school students in Tia
