The development trend of children and adolescents' myopia: increasing year by year, younger
The prevalence of nearsightedness in primary and secondary school students in China is second only to Japan and ranks second in the world. In recent years, the prevalence of nearsightedness among primary and middle school students has increased year by year. According to the results of national student physique monitoring in 2010, the percentage of pupils with myopia detection rate was 40.89%, an increase of 9.22% compared with 2005, and 67.33% for junior high school students, an increase of 9.26% over 2005. Among high school students, 79.2% was an increase of 2.04% compared with 2005. At the same time, the age of myopic patients has also been getting smaller and smaller, and some have even expanded to children and even school-age children. In addition, the age of high incidence of myopia is greatly advanced, the study found that primary and middle school students in Guangzhou City, 7-10 years old began to enter the high incidence of myopia, 12-year-old reached the highest incidence peak. Therefore, it is best to begin myopia prevention before age 7.
Insufficient outdoor activities and other environmental factors can also cause myopia.
From the above data, it can be seen that the status of children and adolescent myopia is very serious. So what are the factors that affect myopia? Yang Xiao, deputy director told the family doctor online editing, myopia factors include environmental and genetic factors. First, genetic factors cannot be ignored. According to the twin studies of the Zhongshan Eye Center, the role and influence of genetic factors on myopia accounted for more than 70%. If both parents are nearsighted, then the risk factors for children suffering from myopia increase. Second, the environmental factors are also very important. Short-distance work, incorrect reading and writing postures, poor view of the environment, lack of outdoor sports, and nutritional factors can cause myopia. A statistical analysis of the incidence of misbehavior in primary and middle school students in Guangzhou showed that 90.7% of the students were short-sighted, 78.5% were working too long, and 63.1% were reading and writing on the desk. Nowadays, due to heavy academic burden, the time for students to participate in outdoor activities is significantly reduced, which greatly increases the probability of students’ myopia.
Prevention of myopia: return to nature and more outdoor activities
For the prevention of myopia in children and adolescents, Deputy Director Yang Xiao said: In fact, the simplest way to prevent myopia is to return to nature and prevent or slow the development of myopia by increasing outdoor activities. According to a survey in Singapore, if students increase their outdoor activities by 1 hour each day, their eye refraction increases by 0.17 D and their axial length decreases by 0.06 mm. The study of the Zhongshan Ophthalmic Center also shows that the school adds a 40-minute extracurricular exercise every day, which can effectively reduce the cumulative incidence of myopia in students by 9.1%. She emphasized that the focus of outdoor activities is outdoors, not indoor, because the difference between the two is light. Outdoors are natural light. There are red, orange, yellow, green, cyan, blue, and purple colors that are very helpful to the eyes. Therefore, She recommends that students take a 10-minute outdoor break in school and that they can go outside to read or exercise.
In addition to the interview, the online editor of the family doctor also learned that because of the importance of knowing outdoor activities to prevent myopia, Deputy Director Yang Xiao was worried about myopia (400 degrees myopia and 600 degrees myopia). The possibility of myopia is very high. Gao) years ago, she insisted on trying to make her children more outdoor activities. From kindergarten to elementary school, she allowed her children to go to school, and received natural light. Now the child is 14 years old and his visual acuity is still 1.5. Therefore, parents of the majority of parents may wish to refer to the reference. If time permits, sending children to school every day by walking will not only improve their physical fitness but also prevent myopia.
Of course, in addition to increasing outdoor activities, there are also ways to prevent myopia, such as reducing close work, changing the incorrect reading and writing posture, and using less electronic products. In addition, studies have found that if children improve their dietary patterns, intake of more carbohydrates, fats, and energy, with a fine mix of ingredients and meat and vegetables, can also play a preventive role in myopia.
