Analysis of Myopia Status and Influencing Factors of Children and Adolescents in Honggu District of Lanzhou
OBJECTIVE To understand the prevalence of myopia among children and adolescents in Honggu District of Lanzhou,and explored the influencing factors of myopia,so as to provide basis for myopia prevention and control.METHODS In 2023,stratified cluster sampling method was adopted to conduct visual acuity examination and questionnaire survey among students in 9 schools,analyze the current myopia situation and the influential factors of myopia by orderly logistic regression.RESULTS The total myopia rate of 2 354 children and adolescents was 64.61%.Although there was no difference in the myopia rate of left eye and right eye,SEl of left eye was higher than SEr of right eye(Z=-8.802,P＜0.05).Monocular myopia accounted for 23.34%of the total myopia.Low,moderate and high myopia accounted for 57.92%,32.15%and 9.93%of the total myopia,respectively.The myopia rate of female students was higher than that of male students(67.40%&61.82%)(χ2=8.022,P＜0.05).The myopia rate increased with the increase of school stage and age.In kindergarten and children under 9 years old,monocular myopia and low degree myopia accounted for the majority.The majority of primary school,junior middle school and secondary school students were low myopia,and the majority of high school students were moderate myopia.Orderly logistic regression analysis showed that adjusting the height of desks and chairs according to height(OR once a semester=0.590,OR once a school year=0.685)and doing eye exercises(OR=0.714)were protective factors for vision.Parental myopia(OR=2.301),activities in the classroom building during recess(OR=1.411),homework/reading after school≥3 hours(OR=1.429),outdoor activities＜3 hours(OR1～2h=1.303,OR2～3h=1.349)were the risk factors for myopia.CONCUSION Children and adolescents in Honggu District of Lanzhou have relatively high myopia.Regular monitoring of visual acuity,eye exercise,increasing time for outdoor activities,regularly adjusting the height of desks and chairs,and appropriately reducing the study burden were potential effective measures to protect visual acuity.
