Analysis on current ametropia of tibetan,Han and Yi high school students in Ganzi Prefecture in 2022
Objective To investigate the current characteristics of refractive errors and anisometropia among high school students in Ganzi Prefecture,and to provide theoretical basis for prevention and control.Methods In October 2022,the cluster sampling method was used to select high school and secondary vocational school students covering 18 counties in Ganzi Prefecture,and computer optometry with remote vision and non-ciliary paralysis was performed by professionals.Chi-square test was used to compare the difference in the detection rate of myopia,farsightedness,astigmatism,anisometropia,myopia degree and astigmatism degree between urban and rural areas,gender and ethnic groups,and P＜0.05 was considered statistically significant.Results A total of 1 592 senior high school students were investigated,including 769 boys and 823 girls.There were 587 urban students and 1 005 rural students;1 119 Tibetan students,367 Han students and 106 Yi students.The detection rate of myopia was 64.45％.The rate of farsightedness was 13.07％.The rate of astigmatism was 63.57％.The deviation rate of farsightedness was 1.88％.The deviation rate of myopia was 9.23％.The deviation rate of astigmatism was 15.64％.And the rate of heterogeneity was 4.59％.In terms of myopia rate and myopia astigmatism rate:the rates of girls(70.84％,54.53％)were higher than those of boys(57.61％,42.52％)(x2=30.37,22.58,respectively,all P＜0.05);and the rates of urban students(73.91％,53.66％)were higher than those of rural students(59.50％,45.77％)(x2=29.09,9.24,respectively all P＜0.05).The myopia rate of Han students(70.03％)was higher than those of Tibetan(64.34％)and Yi students(45.27％)(x2=20.35,P＜0.001).The myopia astigmatism rate of Tibetan students(51.12％)was higher than those of Han(44.68％)and Yi students(36.79)(x2=8.62,P=0.013).The detection rates of myopia of girls(70.84％)and urban students(73.91％)were higher than their detection rates of astigmatism(65.85％,65.93％)(x2=4.72,6.75,respectively all P=0.009).The difference detection rates of astigmatism of different populations were higher than those of myopia(x2=412.16,432.26,288.06,557.24,568.52 and 202.34,respectively,all P＜0.05).The degree of myopia was the highest in the population with severe prevalence composition,higher in the population with moderate prevalence composition,and the lowest in the population with mild prevalence composition(x2=170.19,198.59,147.29,222.16,134.86,78.55 and 9.86,respectively,all P＜0.05).The degree of astigmatism was the highest in urban and Han students with moderate prevalence composition,higher in students with mild prevalence composition,and the lowest in the students with severe prevalence composition(x2=82.97,47.96,all P＜0.05).The degrees of astigmatism in boys,girls,rural,Tibetan,Han and Yi students were just opposite to the degrees of myopia(x2=53.01,40.38,82.97,128.74,164.2,47.96 and 33.07,all P＜0.05).There was no statistical significance in the detection rates of hypermetropia and anisometropia(all P＞0.05).Conclusions In addition to the high detection rate of myopia,the detection rates of astigmatism,farsightedness and anisometropia among high school students in Ganzi Prefecture were also high.The prevention and control of refractive errors among students in Ganzi Prefecture should pay attention to their differences,and scientific and effective intervention measures should be taken against the pathogenic factors.
