According to the results of the National Child and Adolescent Myopia Survey in 2018, the incidence of total myopia in children and adolescents in China is severe. In 2018, the overall myopia rate of children and adolescents nationwide was 53.6%. Among them, 14.5% for 6-year-old children, 36.0% for primary school students, 71.6% for junior high school students, and 81.0% for high school students. The task of prevention and control of myopia is arduous.
In the second half of 2018, the National Health and Health Committee (hereinafter referred to as the “National Health and Health Commission”) organized the 2018 National Child and Adolescent Myopia Survey with the Ministry of Education and the Ministry of Finance. The survey covered a total of 1033 kindergartens and 3,810 primary and secondary schools nationwide. The total number of screenings was 1,117,400, including 69,200 children in kindergartens (6 years old) and 1,408,200 students in all grades.
At present, the problem of myopia in children and adolescents in China is relatively prominent. In the elementary and junior high school, myopia rate increased rapidly with the increase of grades. The primary school stage increased from 15.7% in the first grade to 59.0% in the sixth grade. The junior high school increased from 64.9% in the first grade to 77.0 in the third grade. %. Primary and junior high school are the key age stages of prevention and control of myopia in China.
High third grade students with high myopia, that is, children with myopia higher than 600 degrees accounted for 21.9% of the total number of myopia. Because high myopia is one of the blinding eye diseases, it is easy to cause a series of serious complications, which should cause high vigilance and attention.
According to the monitoring, the hazards related to myopia in our country are widespread. For example, 67% of students spend less than two hours of outdoor activities per day, 29% of students have less than one hour, 73% of students do not meet the standard for sleeping hours, and the hours of homework and long-term use are too long. The use of undesirable eye behaviors such as electronic products is widespread. The above is the main factor for the high incidence of myopia, which is an important factor influencing the high myopia rate of children and adolescents in China.
