Analysis of the binocular vision status and influencing factors in myopic children and adolescents
Objective To explore the binocular vision status and influencing factors in myopic children and adolescents.Methods 120 children and adolescents who underwent visual examinations were randomly selected and divided into a secondary school group and an primary school group,each with 60 cases.Using a self-administered questionnaire scale,basic information and myopia status of all children and adolescents were collected,including age,gender,parental myopia,daily outdoor activity time,daily TV time,daily cell phone time,daily computer time,and the number of eye exercises per week.Binocular vision status of myopic children and adolescents and its influencing factors were analyzed.Results Among the 120 children and adolescents,a total of 66 cases of myopia were found,with a myopia prevalence of 55.00%.Among them,there were 27 cases in the primary school group,with a myopia rate of 45.00%,and 39 cases in the secondary school group,with a myopia rate of 65.00%.The myopia rate of middle school group was higher than that of primary school group,and the difference was statistically significant(P<0.05).There was significant difference in myopia severity between primary school group and secondary school group(P<0.05).As the academic stage increases,the rate of mild myopia decreases,while the rates of moderate and severe myopia increase.Through the assignment and univariate analysis,the myopia group had 38 females and 28 males,aged(13.24±1.62)years;both parents were myopic in 24 cases,one parent was myopic in 31 cases,and neither parent was myopic in 11 cases;the daily outdoor activity time was≥2 h in 22 cases,the daily TV time was≥2 h in 40 cases,the daily cell phone time was≥2 h in 35 cases,the daily computer time was≥2 h in 36 cases;the number of eye exercises per week was 0 times in 22 cases,1-3 times in 36 cases,>3 times in 8 cases.In the non-myopic group,there were 35 males and 19 females,aged(10.32±1.42)years;both parents were myopic in 21 cases,one parent was myopic in 13 cases,and neither parent was myopic in 20 cases;the daily outdoor activity time was≥2 h in 35 cases,daily TV time was≥2 h in 21 cases,daily cell phone time was≥2 h in 18 cases,and daily computer time was≥2 h in 17 cases;the number of eye exercises per week was 0 times in 24 cases,1-3 times in 12 cases,>3 times in 18 cases.There was statistically significant difference between the two groups(P<0.05).Logistic regression analysis showed that older age,being female,both parents being myopic,watching TV≥2 h per day,daily cell phone time≥2 h,and daily computer time≥2 h were risk factors for myopia in children and adolescents(P<0.05),and daily outdoor activity time≥2 h,doing eye exercises 1-3 times per week and>3 times per week were protective factors for myopia in children and adolescents(P<0.05).Conclusion The incidence rate of myopia among children and adolescents is high,which is mainly affected by many factors.It is necessary to regulate students'work and rest time reasonably to reduce the incidence of myopia.
