Abstract: Objective To explore the situation of poor vision and vision-related health behaviors among primary school students in Zhengzhou City. Methods A multi-stage stratified random sampling method was used to sample pupils in grades 4-6 in Zhengzhou City to survey vision examination and vision-related health behaviors. The descriptive epidemiological analysis method was used to analyze the vision status and vision-related health behaviors. Univariate and multivariate analysis methods were used to analyze the influencing factors of poor vision among school-age children. Results A total of 2 415 pupils in grades 4-6 in Zhengzhou City were examined for vision and investigated by questionnaire, including 1 221 boys and 1 194 girls, aged 10-13 years. There were 1 815 cases of poor vision, accounting for 75.16%. The proportion of mild visual impairment was the highest, with 1 156 cases, accounting for 47.87%, followed by moderate visual impairment （488 cases, 20.21%） and severe visual impairment （171 cases, 7.08%）. Multivariate Logistic regression analysis showed that gender （OR=0.517）, living in the city （OR=5.888）, living in school （OR=2.210）, reading and writing posture （OR=2.632, 4.699）, attending after-school tutoring classes （OR=5.501）, daily TV watching time （OR=1.440, 1.881, 2.389）, daily mobile phone or computer time （OR=2.307, 2.704, 3.747）, daily homework time （OR=1.736, 1.887, 2.234）, daily outdoor exercise time （OR=0.770, 0.422, 0.394）, and parents did not limit electronic video time （OR=2.019） were influencing factors for the poor vision of pupils in grades 4-6. Conclusion The poor vision of pupils in grades 4-6 in Zhengzhou City is serious. Preventing and controlling the risk of poor vision in school-age children can be achieved by accurately identifying dangerous behaviors with poor vision and giving individually targeted corrections.
