However, its impact on mental health remains underexplored despite indications of pollutant-induced distress. This study examines the causal relationship between air pollution and mental health disorders—such as depression, sleep disorders, ADHD, and OCD—in South Korea. Assessing this relationship is challenging due to the simultaneous occurrence of economic growth, rising stress, and worsening air quality. Additionally, mental health issues have risen despite declining pollution levels post-COVID-19, further complicating the analysis. To address these challenges, we use wind speed and direction as instrumental variables. Our results show significant adverse effects of air pollution on mental health, particularly before 2020. Although the impact diminishes post-pandemic with improved air quality, certain demographic groups remain vulnerable. This study underscores the need for policies safeguarding mental health in at-risk groups, regardless of declining average pollution levels, and contributes to the literature by highlighting effects on less-studied disorders such as ADHD and OCD.</div></div>","PeriodicalId":47780,"journal":{"name":"Ssm-Population Health","volume":"30 ","pages":"Article 101814"},"PeriodicalIF":3.6,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144105703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While prior research has documented racial/ethnic and gender variations in allostatic load, typically assessed by counting biomarkers at extreme levels, few studies have used latent class analysis (LCA) to examine multi-system physiological dysregulation or tested whether these patterns differ across the intersection of race/ethnicity and gender. This study analyzed data from 5743 Black and White adults aged 50 and older in the Health and Retirement Study to address this gap. Based on eight biomarkers representing metabolic, cardiovascular, and inflammatory systems, LCA identified four distinct dysregulation patterns that varied significantly by race and gender. The four classes included: (1) a <em>Healthy Regulation</em> class, identified across all groups but most prevalent among Black men; (2) a <em>Hypertension Dysregulation</em> class, identified specifically among Black men and White women; (3) a <em>Metabolic and Inflammatory Dysregulation</em> class, observed in both Black and White women; and (4) a <em>Hypertension and Metabolic Dysregulation</em> class, observed among Black women and White men. Association analyses revealed that higher educational attainment was significantly linked to reduced odds of metabolic-related dysregulation in all groups except Black men, underscoring the limitations of education alone in mitigating health risks for this group. These findings emphasize the value of an intersectionality framework for understanding how race and gender jointly shape physiological dysregulation patterns and highlight the need for tailored public health strategies that address the specific health risks faced by different population subgroups.</div></div>","PeriodicalId":47780,"journal":{"name":"Ssm-Population Health","volume":"30 ","pages":"Article 101812"},"PeriodicalIF":3.6,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
