Purpose: To investigate relationship between family history of myopia and prevalence of their child's myopia in 5 to 18 years of age.
Methods: 1,101 subjects (male 575, female 526 subjects) who aged 11.2¡¾3.9 years from the 2016 Korea National Health and Nutrition Examination Survey were included. Myopia was defined as at least ?0.50 D spherical equivalent, and divided into low (?0.50 D ¡Â ~ 3.00 D), moderate (?3.00 D ¡Â ~ 6.00 D) and high myopia (¡Ã?6.00 D) group. Family history was divided into four groups (father, mother, both and none myopic). Near work time was divided into less than 1, 1~2, 3 and more than 4 hours/day. Multiple logistic regression analyses between family history and prevalence of myopia were performed after adjusting age and near work time.
Results: The prevalence of myopia and spherical equivalent were 77.7% and ?2.54D for paternal history with myopic, and 72.3% and ?1.82 D for none myopic group (P<0.05). The univariable odds ratio (OR) of myopia was 1.27 in low myopia, 2.35 in moderate myopia and 5.11 in high myopia for both paternal myopia history compared with none myopia history group. In the three groups, the multivariable OR of myopia was 1.75, 4.15 and 10.02 for both paternal myopia history after adjusting age and near work time.
Conclusions: Age, long near work and parental history of myopia were associated with prevalence of myopia. In particular, both parental history of myopia had more effect on the prevalence of their child's high myopia.
