조현병 진단 후 1년 이내 자살 관련 요인: 국민건강보험공단 자료를 이용한 후향적 코호트 연구 = Factors related to Suicide within One year of Diagnosis of Schizophrenia: A Retrospective Cohort Study using National Health Information Database

다국어 초록 (Multilingual Abstract)

This study aims to identify factors related to suicide within one year of schizophrenia diagnosis based on data from National Health Information Database. We obtained data of 102,540 patients diagnosed with schizophrenia between 2007 to 2010 from customized database, which was checked using the National Statistics Organization database and schizophrenia cohort was built. The number of suicide within one year of schizophrenia diagnosis was 615(0.60%), and the risk of suicide within one year was high among patients within age group of 25-34 and patients with medium-low to high economic status. The risk of suicide within one year among male patients was high within age group of 45-54 and patients with medium-low to high economic status. The risk of suicide within one year among female patients was high within patients with high economic status. Age and economic status need to be considered during suicide prevention intervention of schizophrenia patients diagnosed within one year and suicide related factors by sex need to be especially considered.

본 연구의 목적은 국민건강보험공단 자료를 이용하여 조현병 진단 후 1년 이내 자살과 관련된 요인을 규명하는 것이다. 연구대상 자료는 맞춤형 데이터베이스에서 2007년부터 2010년 사이에 조현병으로 진단받은 대상자 102,540명으로 통계청 사망자료를 확인한 후 조현병 코호트를 구축하였다. 연구결과 조현병 진단 후 1년 이내 자살사망자는 615명(0.60%)이고, 1년 이내 자살 위험은 25-34세 집단(adjusted OR, 1.40; 95% CI, 1.06-1.86)과 중하(adjusted OR, 1.86; 95% CI, 1.38-2.50)부터 상위(adjusted OR, 1.89; 95% CI, 1.42-2.51)집단의 경제상태에서 높았다. 남성은 45-54세 집단(adjusted OR, 1.60; 95% CI, 1.05-2.43)과 중하(adjusted OR, 2.66; 95% CI, 1.79-3.95)부터 상위(adjusted OR, 2.18; 95% CI, 1.45-3.28)집단의 경제상태에서 자살 위험이 높았다. 여성은 상위집단(adjusted OR, 1.51; 95% CI 1.01-2.27)에서 자살 위험이 높았다. 따라서 조현병 진단 후 1년 이내 자살예방을 위한 중재 시 연령과 경제상태를 고려해야 하며, 성별에 따른 자살 관련 요인에 초점을 두어야 할 것이다.
