Objective To investigate the prevalence and effect of electronic products on poor eyesight among primary school students in Tianjin,and to provide evidence for the prevention of poor eyesight by using electronic products scientifically.Methods The visual examination and questionnaire survey were conducted among 1 404 primary school students in Tianjin by using stratified cluster random sampling method.Results The detection rate of poor eyesight in primary school students in Tianjin was 43.1%,and the detection rate of girls' poor eyesight (47.4%) was significantly higher than that of boys' (39.2%)(x2 =9.515,P=0.002).The detection rate of poor eyesight increased with the rise of grade,and the difference was statistically significant (x2 =73.246,P<0.01).The differences between poor eyesight detection rate of primary school students and use of electronic products in the dark (x2=10.377),use of computers (x2 =4.962),use of mobile phones (x2 =7.533),use of tablets (x2 =4.392),daily time spend on mobile phones and tablets (x2 =10.454,x2 =5.555),the distance between eyes and the screen of the mobile phone (x2 =7.016) were statistically significant(P<0.05).According to results of Logistic regression analysis,the risk factors of poor eyesight in primary school students were being above second grade,girls,use of electronic products in the dark and daily time spend on mobile phones more than one hour (P<0.05).Conclusion The use of electronic products affects their eyesight,and use of electronic products in the dark and daily time spend on mobile phones more than one hour are risk factors for their poor eyesight.Primary school students should be standardized in their use of electronic products to prevent poor eyesight.
