Summary: | ObjectiveTo explore the relationship between environmental selenium content and myopia among junior high school students.MethodsA total of 600 junior high school students from selenium-rich, selenium-sufficient, and selenium-deficient areas from Enshi(200 from each area) were randomly selected. The prevalence of myopia, serum selenium, and hair selenium, as well as the glutathioneperoxidase (GSH-Px) and selenoprotein P (SEPP-1) and the selenium distributions of staple crops and drinking water, were determined. The z-test was used to compare continuous data between two groups, a one-way analysis of variance was used to compare continuous data between multiple groups, a chi-square test was used to compare the rates, and the Pearson correlation test was performed to investigate the correlation between selenium and myopia.ResultsAll of the junior school students were divided into myopic (n=244, 40.67%) and non-myopic (n=356, 59.33%) groups. The levels of serum selenium, hair selenium, GSH-Px, and SEPP-1 in the se |
