AIM: To understand the status of poor vision and analyze the main influencing factors among primary and secondary school students in a division of the Xinjiang Production and Construction Corps, and provide a scientific basis for prevention and control of poor vision.

METHODS: A total of 12 primary and secondary schools in a divisional urban district and regiment field of the Xinjiang Production and Construction Corps were chosen using stratified cluster random sampling from August to October 2020. A total of 2 982 primary and secondary school students were selected for visual inspections and questionnaires. Logistic regression analysis was used to explore the influencing factors of poor vision.

RESULTS: The rate of poor vision was 65.66% among 2 982 primary and secondary school students in the division of the Xinjiang Production and Construction Corps, with the majority severe poor vision. Furthermore, the rates of poor vision were higher in girls(70.17%)than that in boys(61.47%)(χ²=4.993, P<0.001)and the urban area(70.03%)were higher than the rural area(58.96%)(χ²=38.680, P<0.001)and the Han nationality students(66.83%)were higher than Uyghur students(52.82%)(χ²=19.772, P<0.001). The risk of poor vision increased with age(χ²_trend =300.144, P<0.001), and by the age group ≥18 years old, the rate of poor vision reached 80.47%. The results of the multivariate analysis showed that the women, the age≥13 years old, writing and reading duration every day ≥2h, cram school on weekends and presence of myopia in parents increases the risk of poor vision, increase the outdoor exercise time, sleep time ≥8h, and do eye exercises every day can reduce the occurrence of poor vision.

CONCLUSION: Poor vision rate of primary and secondary school students in the division of the Xinjiang Production and Construction Corps is higher than that of many regions in the country. Girls with the age(≥13 years old)whose parents are myopic should receive special attention. Increasing outdoor exercise time, doing eye exercises every day, and keeping your eyes more than one foot away from books when reading and writing is effective in preventing poor vision.
