Study on the status of low vision among students of Beijing in 2017 / 中华流行病学杂志

ABSTRACT

Objective@#The purpose of this study was to describe the status quo and related factors on low vision (LV) among students of Beijing.@*Methods@#All the students in Beijing were included as the subjects of interest, based on the reference of the Chinese National Survey on Students’ Constitution and Health.@*Results@#The overall rate of LV among students in Beijing was 58.6% in 2017, with 61.6% in females, higher than 55.9% in males. LV also appeared higher in urban than in rural areas. The rates of LV appeared as 46.8%, 78.0%, 89.0%, 71.0%, in students from primary, middle, high or vocational high schools, respectively. Rates on light, moderate or severe LV were 8.4%, 17.8% and 32.5%, respectively.@*Conclusions@#The overall rate of LV among students in Beijing was considered high. Students in preschool, in 4-6 grades and the 2nd grade of middle schools, were at the key stages of developing vision-related problems. Factors as heavy load on homework, lack of outdoor activities and 'limit of vision space’ as well as incorrect reading behavior during puberty, need to be of concern.
