Supplementary file 1_Fine particulate matter (PM2.5) and suicide in South Korea: an instrumental variable analysis using thermal inversion.docx Osung Kwon (14389368) Public Health and Health Services not elsewhere classified fine particulate matter (PM2.5) health instrumental variable analysis (IVA) suicide mortality thermal inversion <p>Air pollution causes the deterioration of both physical and mental health and increases the risk of suicide. Existing studies on the association between air pollution and suicide rely on meta-analyses and simple correlation analyses, which cannot quantify how much the increase in air pollution levels increases suicide rates. This study thus examines the relationship between fine particulate matter (PM_2.5) pollution and suicide mortality in South Korea from 2015 to 2019 using thermal inversions as an instrumental variable to induce exogenous variations in PM_2.5 levels. The findings suggest that a 1 μg/m³ increase in PM_2.5 pollution is associated with a rise of 0.6628 suicide deaths per 1 million population (β = 0.6628, 95% CI: 0.1049–1.2208). The 2.94% increase in suicide mortality highlights the significant health impact of PM_2.5 exposure. Additionally, this study shows the differentiated effects of exposure to PM_2.5 on the suicide mortality rate. An increase in PM_2.5 was associated with higher suicide mortality (deaths per million) in males (7.873), older adults (21.18), individuals with lower education levels (4.091), and those living in non-metropolitan areas (5.434). These impacts are observed among several groups: older adults, males, adults without a college education, and people living in non-metropolitan areas. These results provide empirical evidence for the heterogeneous effect of PM_2.5 pollution on the suicide mortality rates across demographic groups.</p> 2026-09-14T05:38:14Z Dataset Dataset 10.3389/fpubh.2026.1909365.s001 https://figshare.com/articles/dataset/Supplementary_file_1_Fine_particulate_matter_PM2_5_and_suicide_in_South_Korea_an_instrumental_variable_analysis_using_thermal_inversion_docx/33718879 CC BY 4.0
