Analysis of prevalence of common diseases among students in Hedong Dis-trict of Tianjin City from 2019 to 2021
Objective To investigate the prevalence of common diseases among students in Hedong District,Tian-jin City,to provide evidence for exploring the prevention and treatment strategies of common diseases among students in the district.Methods From 2019 to 2021,a total of 7 496 students in 5 primary and secondary schools in Hedong District were monitored for common diseases by stratified cluster sampling,and the chi-square test was used to compare the detection rates of low vision,dental caries,obesity,malnutrition(including growth retardation and wasting),and abnormal spinal curvature among primary and secondary school students of different years,school stages,and genders.Results From 2019 to 2021,the total detection rates of low vision,dental caries,obesity,malnutrition,and abnormal spinal curvature among students in Hedong District of Tianjin City were 72.95％,33.99％,28.60％,7.23％,and 4.59％,respectively.From 2019 to 2021,the de-tection rates of obesity were 27.50％,28.77％,and 29.29％,respectively,and the detection rates of malnutrition were 8.14％,6.73％.and 6.93％.respectively,and the differences were not statistically significant(x2=2.051,P=0.359:x2=4.001.P=2.135).However,there were significant differences in the detection rates of low vision(73.88％,67.40％,and 76.46％),den-tal caries(38.42％,30.14％,and 33.61％)and abnormal spinal curvature(8.41％,2.86％,and 3.05％)in different years(x2=55.195,34.763,106.232,all P＜0.001).The detection rates of low vision in primary school,junior high school,senior high school,and vocational high school(61.37％,80.71％,85.99％,79.95％),dental caries(40.18％,27.29％,27.53％,34.35％),obesity(32.66％,25.89％,27.04％,20.17％),malnutrition(7.51％,5.56％,8.09％,7.70％),abnormal spinal curvature(1.75％,6.04％,7.84％,7.09％)were statistically significantly different(x2=442.019,121.265,63.924,9.302,121.462,all P＜0.05).The detection rates of obesity and malnutrition in boys(34.37％,7.80％)were higher than those in girls(22.27％,and 6.60％),while the detection rates of low vi-sion,dental caries,and abnormal spinal curvature in boys(67.98％,31.13％,2.83％)were lower than those in girls(78.40％,37.13％,6.52％),and the differences were statistically sig-nificant(x2=134.028,4.007,102.960,29.975,58.123,all P＜0.05).Conclusion The detection rates of common diseases such as low vision,dental caries,and obesity among primary and secondary school students in Hedong District of Tianjin City are relatively high,which is the focus of school health work in the future,and targeted intervention activities should be carried out as soon as possible.
