Environmental exposure and biomarker patterns: an exploratory epidemiological piece using mediation-style analysis. Curious readers interested in biological pathways will be engaged.
Key Takeaways
- Cross-sectional study enrolled 1,506 community-dwelling adults aged 60 years and older
- Researchers measured ambient PM2.5 exposure and assessed metabolic syndrome status and serum amino acids
- Moderated mediation analysis tested whether amino acids mediate PM2.5–MetS associations across age and diet
