An Integrative Analysis of Social and Individual Factors Associated with Suicidal Ideation among Korean Adults

Key Points

• This research aims to understand suicidal ideation among Korean adults by analyzing social and individual factors over time.
• Longitudinal study using data from the Korean Welfare Panel (2012-2024) and national data (2010-2022) with 19,694 adults (146,119 cases).
• Applied generalized linear mixed model (GLMM) with logit link for analysis.
• Examined direct effects and interaction effects of social and individual factors on suicidal ideation.
• Increased social welfare budget ratios and suicide prevention reporting guidelines are associated with lower risk of suicidal ideation.
• Higher socioeconomic status, subjective health, and social capital correlate with reduced suicidal ideation risk, while deprivation and depression elevate risk.
• Income inequality amplifies the disparity in suicidal ideation risk based on socioeconomic status, but high social welfare expenditure mitigates this risk.
