本文通过对某市郊609名12～16岁初中学童的视力不良调查,计算出学生的近视平均初发年龄为13岁8个月,其中94％在11岁2个月～16岁1个月之间开始形成近视。男女相同,有家族史者近视平均初发年龄(13岁5个月)比无家族史者(13岁11个月)提前6个月。对男女近视平均初发年龄与男女青春期生长发育突增期的对比分析以及正视和近视身高平均值的比较提示,近视发生与生长发育无直接内在联系。
Based on a survey of poor eyesight among 609 junior middle school students from 12 to 16 years old in a suburb, the average initial onset of myopia was calculated as 13 years and 8 months, of which 94% were between 11 months and 2 months and 16 months and 1 month Between the formation of myopia. The same as men and women, with a family history of myopia average age of onset (13-year-old 5 months) than no family history (13 years and 11 months) 6 months earlier. Comparison of the mean initial onset age of myopia in men and women with the sudden growth of men and women during adolescence as well as the comparison of height and average height of myopia and myopia suggest that there is no direct relationship between myopia and growth and development.
