Abstract

Background: Refractive errors in school children is a public health problem, increasing rapidly in many countries around the world, including Vietnam. Objectives:  Determine the rate and some factors related to refractive errors in secondary school children aged 11 to 14 years old in Soc Trang province in 2020. Materials and methods: A cross-sectional descriptive study. The study was conducted on 3.188 secondary school children aged 11 to 14 years old at 6 secondary schools in Soc Trang province from September 2020 to December 2020. Results: Among 3.188 screened students, 716 students were diagnosed with refractive errors, the overall rate was 22.5%, of which myopia accounted for the highest rate of 66.5%, followed by astigmatism 32.8% and the lowest hyperopia 0.7%; Refractive errors were mild 63%, moderate 28.9%, severe 4.6% and very severe 3.5%. Refractive errors also increased gradually with age, the rate of refractive error at 11, 12, 13 and 14 years old was 16.2%, 21.0%, 24.0% and 30.6%, respectively. Some factors related to refractive errors include: study time, playing video games, watching television, outdoor activities and sports. The more time a student spent studying outside of school, playing video games, watching television, the higher the risk of refractive errors, the more time spent outdoor activities and doing sports, the lower the risk of refractive errors. Conclusion: The overall rate of refractive errors in students 11 to 14 years old was 22.5%, it is necessary to pay attention to building intervention models to control refractive errors.
