Suicide among Korean middle school students is a growing social concern. Exploring factors associated with suicide ideation is important for suicide prevention in middle school adolescents. The purpose of this study was to identify risk factors influencing frequency of suicidal ideation among middle-school students in Korea.


The study was a cross-sectional descriptive study. The participants were 391 middle school students and data were obtained from the 13th wave of Korean Welfare Panel Study in 2018. Zero-inflated Negative Binomial Regression model was employed to identify risk factors.


Among participants, 67.3% reported they did not have current suicidal ideation. By zero- inflated negative binomial regression analysis, gender, grade, and peer attachment were found to be significant predictors in the count model, and depression/anxiety and parental neglect were found to be significant predictors in the logistic model. These findings suggest that middle school adolescents who were female, 3rd grade students, or had lower peer attachment were associated with increased severity of suicidal ideation. Also, depression/anxiety and parental neglect were identified as risk factors affecting the future likelihood of suicidal ideation among middle school adolescents.


Identified risk factors affecting severity and possibility of suicidal ideation may help health care providers to tailor effective suicide prevention interventions for middle school students.

본 연구는 지역사회 거주 당뇨노인의 인지기능의 변화궤적 양상을 확인하고자 하였다. 한국복지패널 1차년도부터 6차년도 자료를 활용하여, 당뇨진단을 받은 65세 이상의 노인 672명의 자료를 분석하였 다. 성장혼합모형 분석 결과, 당뇨노인의 인지기능의 변화양상은 ‘정상-유지형’ (41.5%), ‘정상-저하형’ (23.8%), ‘경도인지장애-유지형’ (17.1%), ‘경도인지장애-저하형’ (11.2%), ‘중증인지장애-저하형’ (6.4%) 의 5가지 유형으로 확인되었고, 연령, 성별, 가계소득, 자기보고 건강상태가 영향 요인으로 확인되었다. 본 연구 결과를 통해 당뇨노인의 인지기능의 변화 양상은 이질적이며, 당뇨노인의 인지기능 저하를 예방 하기 위해 대상자에 대한 개별적인 이해와 맞춤형 중재가 필요함을 확인할 수 있었다.
