ABSTRACT
Objective@#To analyze the relationship between sleep and poor vision of primary and middle school students aged 7-18 years, and to provide evidence for further student eye health promotion.@*Methods@#Data was collected from the Chinese National Survey on Students’ Constitution and Health in 2014. A total of 173 555 primary and middle school students were examined with the 5 m standard visual acuity chart. Sleep, homework time, milk consumption and exercise duration were collected by questionnaire survey.@*Results@#Only 5.60% of students aged 7-18 years had enough sleep, and the poor vision rate among students with insufficient sleep was higher than that of students with sufficient sleep(69.11% vs 67.76%), and the difference is statistically significant(χ2=7.87，P=0.01). After adjusted for other related factors, it showed that students’ sleep was closely related to poor vision(P<0.01), and adequate sleep was the protective factor of students’ poor vision (OR=0.92，95%CI=0.88-0.96).@*Conclusion@#Adequate sleep is conducive to preventing the occurrence of poor vision of primary and secondary school students in China. We should take measures to ensure that students get enough sleep.
