Abstract Details

Purpose:

To evaluate the individual and parental factors of myopia in Korean children.

Setting:

A total of 3,438 subjects aged 7 to 18 years along with both individual and parental ocular examination data information were obtained from KNHANES 2008-2012.

Methods:

All subjects and their parents underwent non-cycloplegic auto-refractometry, physical examinations and an interview. we use the more myopic eye between both eyes in this study.

Results:

Mean refractive error was −2.15±2.28 diopters(Range:-13.25~5.50). Prevalence of myopia (defined as as ≤ -1.00 diopters in the right eye) was 66.9%, and prevalence of high myopia myopia (≤-6.0 diopters) was 8.6%. In multiple logistic regression analysis of factor, a higher prevalence of myopia was associated with Age, Obesity, Home income, Parental myopia. In multiple logistic regression analysis, higher prevalence of high myopia was associated with Age, Obesity, Parental myopia. The more increased the level of parental myopia, it was increased the prevalence of their children's myopia and high myopia. And it was positive correlation between spherical equivalent of parents and child.

Conclusions:

Our findings show that age, home income, obesity, parental myopia were associated with myopia and high myopia in children. Prevalence of myopia and high myopia were more associated with involvement of both parents than of a single parent. The higher degree of myopia of parents, their child had more prevalence and higher level of myopia. This supports a genetic factor into myopia development. And if parents are myopic, they need more attention to manage children’s myopia.
