Abstract：Objective To survey the current status of myopia and its affecting factors among primary and secondary school students in Puyang City, and to provide a reference basis for adopting appropriate myopia intervention measures. Methods A stratified cluster random sampling method was used to select 4,804 primary and secondary school students from 16 schools in 1 district and 2 counties of Puyang City. Visual examination was performed, and then we conducted a questionnaire survey to investigate the factors affecting poor eyesight. χ2 test was applied to comparing the prevalence rate of myopia among different groups, and logistic regression model was employed to identify the factors affecting the occurrence of myopia. Results In 2021, the detection rate of myopia among the primary and secondary school students in Puyang City was 69.61%, with 73.45% for female students and 65.95% for male ones and showing a statistically significant difference (P<0.001). With the increase of school stage, the detection rate of myopia showed a significant upward trend (P<0.001). Multiple logistic regression model revealed that lying down reading books or watching electronic screens (OR=1.315, 95%CI:1.077-1.605) was a risk factor for myopia. Adjusting the height of desks and chairs based on students’ height (OR=0.844, 95%CI:0.732-0.974), doing eye exercises at school (OR=0.717, 95%CI:0.621-0.828), keeping the distance between the eyes and the book one foot while reading and writing (OR=0.765, 95%CI:0.666-0.879), the teacher reminding students to pay attention to reading and writing posture (OR=0.840, 95%CI:0.732-0.964), keeping the distance between the eyes and the TV screen 3 meters while watching TV (OR=0.862, 95%CI:0.748-0.994), short-rest interval of eyes during near work (OR=0.720, 95%CI:0.619-0.838) and sufficient sleep time (OR=0.807, 95%CI:0.687-0.949) were protective factors for myopia. Conclusion The detection rate of myopia among the primary and secondary school students in Puyang City in 2021 was at a high level. Reducing the time of near work and maintaining good habits of using eyes and reading and writing posture are crucial for improving the current condition of myopia.
