Yunnan Province Mo Jiang County Middle School Students Myopia Prevalence And Influence Factors Of Research

Objective:To investigate the ocular diseases,refractive status and related factors of middle school students in Mo jiang County,and to understand the risk factors that affect the occurrence and development of myopia,and to explore the effective methods for the prevention and cure of myopia.Methods:15 secondary schools in Mo jiang County were randomly selected,and 10 of them were extracted,and the first-grade students of junior high school were studied.Take a census to fill in the questionnaire,and height,weight,waist circumference,blood pressure,eyesight,optometry,intraocular pressure measurement,external eye and Anterior section inspection,scattered pupil,fundus examination,fundus photography,Len-star examination,and statistical analysis of the data.Results:1?Into the investigation for 2385,register at the actual number is 2346,b.at a rate of 98%.Male,1209 people,51.53%of the total,1137 women,48.47%of the total.The disease constituent ratio;53.5%for normal students,refractive errors by 41.7%,30.4%myopia students,astigmatism students 20.0%(myopic astigmatism and hyperopia astigmatism),hyperopia students 1.2%,0.4%strabismus and amblyopia was 1.4%,other 3.0%(other eye diseases include:conjunctivitis,keratitis,corneal opacity,cataract,retinal disease,other unknown causes diseases.2?Prevalence statistics:normal people is 55.2%,the prevalence of refractive error is 43.0%,31.4%prevalence of myopia,astigmatism(including myopic astigmatism and hyperopia astigmatism)prevalence rate 20.6%,farsightedness prevalence of 1.2%,0.4%strabismus and amblyopia is 1.4%.Mainly to myopic refractive error in the middle of refractive errors.The prevalence of myopia is 31.4%,which was 24.5%of men and women prevalence is 38.7%,male and female on the myopia prevalence difference was statistically significant(P = 0.000<0.000),3?Yi myopia rate is 40.1%,the han nationality myopia rate is 37.9%,the ha ni myopia rate is 27.2%,other 36.2%.All nationalities in myopia rate statistical differences(p=0.000<0.001)?4?The survey found that myopia group of students is relatively not myopia group of students,learning pressure,good grades,bad habits with the eye,eye each use long duration and do homework every night time,comparing the two groups,the difference was statistically significant(P<0.05);Everyday with the longer computer use the higher prevalence of myopia.Myopia recess outdoor activity time is shorter than no myopia group,students myopia prevalence rate is high,the two groups of comparison,the difference was statistically significant(P<0.05).There is no statistical difference of partial eclipse or not in approximate prevalence(P=0.357>0.05),found that obesity in myopia is higher than the proportion of non-myopia groups,the two groups of comparisons,the difference is statistically significant(p<0.05)?Myopia of the students more students than the myopia students application of desk lamp,also statistically significant difference between the two groups(P<0.05),while students failed to timely correction of myopia group,the number of people can't see the blackboard is significantly higher than the myopia group,differences between the two groups was statistically significant(P = 0.000<0.001).5>Lunch break:in an indoor lunch nap outdoors myopia prevalence is less than the myopia prevalence(P<0.01).Myopia students to take a nap frequency is less than the myopia students differences between the two groups was statistically significant(P<0.05).6?Parents of children myopia prevalence of myopia or not,no statistical difference between the two groups(P>0.05),with the increasing of parents,level of education,children myopia prevalence increased,then the difference between the two groups(P<0.001),parents' occupation related to children myopia prevalence:teachers,doctors,researchers>administrative cadres(officials)>laborer>the farmer workers,(P<0.001).7?Myopia risk factors comprehensive analysis results showed that the OR>1:homework after school time,parents' cultural degree is high.OR<1:grades,homework after school time,recess activity do,weekends,holidays,on average,use a computer every day can clearly see the blackboard,lunch time,sitting,and so on in indoor OR outdoor,lunch break if I take a nap.Conclusions:1?Survey found that the MoJiang County middle school students myopia prevalence is lower than other parts of the domestic,girl prevalence is significantly higher than boys,prevalence of various nationalities have obvious differences:the hani yi>han>>other nation.Close your eye time increased the incidence of myopia.2?MoJiang County risk factors for middle school students myopia:father's cultural degree is high,high degree of mother culture,after-school homework time is long,the protection factors of myopia is:the poor school performance,sitting position can see on the blackboard,after-school learning time is short,break to participate in outdoor activities,more less time with the computer and take a nap during my lunch break and for outdoor activities.
