Abstract
Purpose: :
To estimate the prevalence of high myopia considering regional distribution in 19 years old men in Southeast Korea at 2006.
Methods: :
This retrospective study was based on medical checkup data of conscription by the Military Manpower Administration of Korea from January to December 2006. Study subjects were the whole 19 years old men in Southeast Korea(Gyeongnam province including 20 cities and counties, Ulsan and Busan metropolitan city). Health checkup data of conscription consisted of noncycloplegic autorefraction test, biometric data and social factors. To analyze social and biometric effects, we classified biometric factors into 4 groups, blood pressure into 4 groups by 7th report of JNC, BMI into 5 groups by WHO criteria and social factors into 3 groups, respectively. High myopia was defined as a spherical equivalent(SE) of less than -6.0D. The prevalence of high myopia was adjusted by direct standardization method. Data analysis was performed with descriptive analysis, chi square test and multiple logistic regression using the SPSS(version 14.0K) program.
Results: :
The prevalence of high myopia was 11.62% (5,856/50,401). The adjusted prevalences of high myopia for administrative district were 11.27% in Busan metropolitan city, 10.77% in Ulsan metropolitan city and 12.22% in Gyeongnam province, respectively. The prevalence of high myopia was highest in Dong- Rae Ward in Busan metropolitan city(14.18%) and lowest in Uiryeong county in Gyeongnam province(4.22%). The risk factors of high myopia were urban area(OR=2.11, 95% CI 1.79-2.48 in city; OR=2.02, 95% CI 1.72-2.37 in metropolis), academic achievement(OR=1.44, 95% CI 1.34-1.54 in students of 4-year-course university and over) and hypertension(OR=1.40, 95% CI 1.16-1.69 in stage I hypertension; OR=1.59, 95% CI 1.05-2.40 in stage II hypertension).
Conclusions: :
More than one tenth of young men were high myopia as one of the risk factor for eye health and prevalences of high myopia for each administrative district were various. Further studies, community prevention programs and health promotion services considering community eye health status are needed to improve high myopia in young men
