Abstract:
Objective To analyze the prevalence of visual acuity disorder among children aged 4-18 in Xuhui District of Shanghai from 2015 to 2019, and analyze its influencing factors, and to provide a scientific basis for the prevention and control of visual acuity disorder in Xuhui District of Shanghai. Methods Using random cluster sampling, students from 10 kindergartens, 3 primary schools and 2 middle schools were randomly selected as the investigation subjects. Visual acuity examinations and demographic survey were conducted, and chi-square test was used to describe the development trend of poor visual acuity. Results A total of 29 613 people were screened in five years, and the detection rate of poor vision in Xuhui District of Shanghai from 2015 to 2019 was 41.08% in 2015 and 50.59% in 2018, showing an increasing trend year by year (χ2=127.45, P<0.05). The detection rate of poor vision was 86.72% in high school and 11.95% in kindergarten. The detection rate of poor vision increased with the grade, and the difference was statistically significant (χ2=7237.84, P<0.05). The overall detection rate of poor vision in children aged 4-18 was higher in girls than in boys, and the difference was statistically significant (χ2=80.93, P<0.05). The detection rate of poor vision among students of 4-6 years old born in autumn was 9.29%, which was lower than that in the other three seasons, and the difference was statistically significant (χ2=12.91, P<0.05). Conclusion In Xuhui District, the detection rate of poor vision among children and adolescents aged 4-18 years old was relatively high, and the development trend of visual problems was severe. In order to prevent the occurrence and development of poor eyesight, education departments, health departments and parents should strengthen the cultivation of good eye use habits and awareness among students, and take reasonable measures to control the development of poor vision.
