Abstract

Objectives : The study aimed to identify factors associated with suicidal attempt in Korean adults experiencing thoughts of suicide. Methods : This study analyzed outcomes of suicidal behavior in the Korea National Health and Nutrition Examination Survey (KNHANES) 2015, 2017, and 2019. This survey was administered by the Korea Centers for Disease Control and Prevention (KCDC). The suicidal idea group was divided into individuals who had attempted suicide (n=92) and those who had not (n=831). Complex samples crosstabs analysis was conducted to compare the two groups' sociodemographic, psychiatric, and clinical characteristics. In addition, factors related to attempted suicide were investigated using complex samples logistic regression analysis. Results : The attempted suicide group had significantly higher rates of depression, recent psychiatric counseling, and suicidal plan (p<0.001) than the non-attempting group. In addition, the groups differed significantly in the frequency of binge drinking and smoking (p<0.05). Adjusted multivariate analysis revealed that the presence of a suicidal plan (Odds ratio [OR]=8.46, 95% Confidential Intervals [CI]=4.72-15.00), daily binge drinking (OR=3.14, 95% CI=1.26-7.84), psychiatric counseling within the past year (OR=3.03, 95% CI=1.75-5.23), low income level (OR=2.89, 95% CI=1.17-7.10), and history of depression (OR=2.39, 95% CI=1.29-4.42) were significantly associated with suicidal attempt. Conclusions : Factors associated with suicidal attempt among suicidal ideators in the general Korean population were identified across all sociodemographic, psychiatric, and clinical variables. Assessment of and intervention in suicidal plan, binge drinking, income level, and depression might prevent progression to suicidal attempt among those contemplating suicide.

연구목적 자살관념이 있는 한국성인에서 자살시도와 연관된 요인을 규명하고자 하였다. 방 법 질병관리청에서 매년 실시하는 국민건강영양조사 중 자살행동을 조사한 2015, 2017, 2019년도 결과를 분석하였고, 만 19세 이상 성인을 대상으로 하였다. 자살관념자를 자살시도군(n=92)과 비자살시도군(n=831)으로 나누었고, 복합표본 교차분석으로 두 군의 사회인구학적, 정신의학적, 임상적 특성을 비교하였다. 복합표본 로지스틱 회귀분석으로 자살관념자에서 자살시도와 연관된 인자를 조사하였다. 결 과 자살관념자 중 자살시도군에서는 비자살시도군에 비해 우울증 진단 병력, 자살시도 전 정신의학적 상담 경험, 자살계획이 유의하게 많았다(p<0.001). 또한 두 군은 소득 수준, 폭음 빈도, 흡연 빈도에서 유의한 차이를 보였다(p<0.05). 다변량 분석 모형(Adjusted model)에서 자살계획이 있는 경우(Odds ratio [OR]=8.46, 95% Confidential Intervals [CI]=4.72-15.00), 매일 폭음을 하는 경우(OR=3.14, 95% CI=1.26-7.84), 최근 1년 동안 정신의학적 상담 경험이 있는 경우(OR=3.03, 95% CI=1.75-5.23), 소득 수준이 낮은 경우(OR=2.89, 95% CI=1.17-7.10), 평생 우울증을 진단받은 적이 있는 경우(OR=2.39, 95% CI=1.29-4.42)가 자살시도와 통계적으로 유의한 연관성이 있었다. 결 론 우리나라 일반인구의 자살관념자에서 사회인구학적, 정신의학적, 임상적 변수 모두에 걸쳐서 자살시도의 위험요인이 나타났다. 자살관념이 있는 환자들에서 자살계획, 문제음주, 소득수준, 우울증 병력 등을 평가하고 개입하는 것이 자살시도로의 이환을 방지해 줄 가능성이 있다.
