Abstract: Objective To analyze epidemic status and influencing factors for the poor vision of the students in Henan in 2014 and to provide the scientific basis of more targeted myopia prevention strategies. Methods The data of 34 886 students aged 9 to 18 who were involved in the students' physical fitness survey in Henan province in 2014 was used to analyze epidemic status and influencing factors for the poor vision. Results The prevalence rate of myopia among Henan students was 62.5%. In addition, high school was higher than middle school which was higher than primary school. Girl was higher than boy, and urban was higher than rural. Through the unconditional logistic regression, having breakfast three to five times a week, eating eggs three to five times a week, drinking milk unusually, doing exercise over two hours a day, and watching TV over two hours a day were the protective factors for poor vision, of which the OR were 0.850, 0.883, 0.864, 0.830, 0.738 respectively. Correspondingly, the 95% CI were 0.776-0.931, 0.813-0.960, 0.812-0.920, 0.722-0.955, 0.681-0.799. While sleeping less than seven hours, PE class one time a week or less, refusing to run long-distance, doing homework over two hours, and playing the e-productions over two hours were the risk factors of which OR were 1.100, 1.091, 1.100, 1.375, 1.155 respectively. Correspondingly, the 95% CI were 1.009-1.199, 1.017-1.172, 1.024-1.183, 1.287-1.469, 1.072-1.244. Conclusions The rate of the myopia among the students in Henan is still severe. There are multifarious factors related to poor vision. Therefore, much more targeted measures should be taken to prevent poor vision from developing.
