Gender, grade, parents＇ myopia history, outdoor activity time and video display terminal time were collected through the questionnaire of National Surveillance Program of Influencing Factors for Common Diseases and Health in Students. Uncorrected visual acuity and cycloplegic refraction were tested. Multivariate logistic regression analysis was performed to explore myopia-related factors.
Results:A total of 990 questionnaires were distributed, and 882 valid questionnaires were recovered, with an effective rate of 89.09%. The prevalence rate of myopia was 78.23% ( 690 cases ). Multivariate logistic regression analysis showed that females ( OR=1.703, 95%CI: 1.173-2.474 ) , middle school students ( OR:5.597-11.949, 95%CI: 3.573-28.349 ) , both parents＇myopia ( OR=2.445, 95%CI: 1.597-3.742 ) , video display terminal time over 3 hours per day ( OR=2.026, 95%CI: 1.235-3.325 ) were risk factors for myopia; outdoor activity time over 2 hours per day ( OR: 0.493-0.510, 95%CI: 0.273-0.943 ) was a protective factor for myopia.
