Abstract
BACKGROUND
Influenza vaccine coverage among the elderly is important for informed vaccination policies and programs. There are few studies that define influenza coverage in the elderly in South Korea. The aim of this study is to examine influenza vaccination coverage among those 65 years old and older in South Korea over the 2004-2005 influenza season and to identify the socioeconomic and clinical factors associated with vaccination. METHODS: We analyzed data retrieved from The Third Korea National Health and Nutrition Examination Survey (KNHANES III) 2005 conducted by the Korea Centers for Disease Control and Prevention. Subjects included in this study were older than 65 years. We used questionnaires to obtain information regarding demographics, chronic diseases, and individual health behavioral risk factors. Univariate analysis, logistic regression, and trend test were performed. RESULTS: There were 1,097 persons included in this study. Influenza vaccination among those 65 years old and older was 77.2 %. There was no difference of coverage by sex, education level, and income status. For elderly females, the moreunheal thy lifestyle (currently smoking, heavy alcohol use, and no exercise) that was practiced, the less likely they wereto be vaccinated (p for trend=0.007). CONCLUSION: The influenza vaccination coverage rate among the elderly in South Korea during the 2004-2005 flu season was relatively high compared to that of Europe (19.3-26.5 %) during the same season. Nevertheless, the coverage rate in elderly women with unhealthy lifestyle was not satisfactory causing them to be more vulnerable to related illnesses than those who practiced a healthy lifestyle. To prevent influenza related illnesses, clinicians should, in particular, encourage vaccination in those with an unhealthy lifestyle, as well as, lifestyle modification.

연구배경: 노인에서의 인플루엔자 접종률에 대한 추정은 정책과 프로그램에 중요한 자료이다. 그러나, 이에 대한 국내의 연구는 미미한 실정이다. 본 연구는 2004-2005년 시즌의 65이상 성인에서 인플루엔자 접종률을 알아보고, 이와 관련된 사회경제학적, 임상적 요인들을 알아내는 데 있다.

방법: 국민건강영양조사 제3기의 자료를 이용하였으며, 연구 대상은 65세 이상의 성인이었다. 인구학적 특성 변수와 만성 질환 유무, 개인 건강 행태 요인 변수를 사용하였다. 단변량 분석과 다변량 분석, 추세 분석 등을 시행하였다.

결과: 연구 대상자 수는 1,097명이었으며, 65세 이상에서 인플루엔자 백신 접종률은 77.2%였다. 성별, 교육수준이나 수입에 따른 차이는 관찰되지 않았다. 노인 여성에서 건강하지 못한 생활습관(현재흡연, 과음, 비운동)을 많이 가진 군의 접종률이 유의하게 낮았다(p for trend=0.007).

결론: 우리나라의 노인에서 인플루엔자 백신 접종률은 2004-2005년 시즌의 경우 유럽의 국가들과 비교하여 높은 수준이었다. 그러나 건강하지 못한 생활습관을 가진 노인 여성의 인플루엔자 백신 접종률은 만족스럽지 못하며, 이들은 인플루엔자에 더욱 취약할 것이다. 일차 의료현장에서 이와 같은 실태를 감안한 백신 접종 전략이 필요하다.
