목적: 부산, 울산 및 경남지역 19세 남자의 근시 및 고도근시 유병률을 추정하고 거주지역, 학력수준, 신장, 체중 등의 영향을 분석하였다. 대상과 방법: 2002년 1월에서 12월까지 부산, 울산, 경남지역에 거주하는 징병신체검사자 중 시력이 0.8 이하인 사람 50,243명에게 시행된 자동굴절검사 결과를 분석대상으로 하였다. 굴절이상이 -0.5D 이상이면 근시로, -6.0D 이상이면 고도근시로 정의하였으며 거주지역, 학력수준, 신장, 체중 등에 따라 표준화하여 유병률을 비교하고 굴절검사 누락자를 활용하여 추정 유병률을 계산하였다. 결과: 조사대상자의 근시 유병률과 고도근시 유병률은 각각 45.60% (95% CI: 45.17~46.03), 11.50% (95% CI: 11.23~11.77)로 나타났으 며 1차 시력검사 결과 0.5 이하이면서 2차 굴절검사를 시행하지 않은 자 9,575명을 고려한 추정 근시 유병률은 54.31% (95% CI: 53.88~ 54.74)이었다. 결론: 부산, 울산 및 경남지역 만19세 남성의 근시 유병률은 45.60%, 추정 근시 유병률은 54.31%, 고도근시 유병률은 11.50%로 나타났다.


Purpose: To investigate the prevalence of myopia and its influencing factors in an epidemiologic study of conscripts living in Gyeongsangnam-do, Ulsan and Busan. Methods: A cross-sectional study was conducted in 19-year-old conscripts in Gyeongsangnam-do, Ulsan and Busan. Health checkup data of the conscripts were collected and analyzed along with subjective visual acuity, noncycloplegic autorefraction test, biometric data, and social factors such as education level and residence area. Myopia and high myopia were defined as having a refractive error of more than -0.5D, -6.0D, respectively. To analyze the social and biometric effects, we classified social factors into three groups and biometric factors into five groups. The estimated myopic prevalence was calculated adding excluded conscripts who scored under 0.5 on the subjective visual acuity test and missed autorefraction data. Data analysis was performed with descriptive analysis and the chi square test for trends using the Statistical Package for the Social Sciences (SPSS) version 14.0K. Results: From 66,917 eligible conscripts, 50,243 were analyzed. The prevalence of myopia and high myopia in 19-year-old men in Gyeongsangnam-do, Ulsan and Busan were 45.60% (95% CI: 45.17~46.03) and 11.50% (95% CI: 11.23~11.77). The estimated myopic prevalence using 66,917 eligible conscripts was 54.31% (95% CI: 53.88~54.74). Conclusions: The prevalence of myopia and high myopia and the estimated prevalence of myopia in 19–year-old men in Gyeongsangnam-do, Ulsan and Busan were 45.60%, 11.50% and 54.31%, respectively.
