Survival analysis of long-term exposure to different sizes of airborne particulate matter and risk of infant mortality using a birth cohort in Seoul, Korea
Background Several studies suggest that airborne particulate matter (PM) is associated with
infant mortality; however, most focused on short-term exposure to larger particles. Objectives
We evaluated associations between long-term exposure to different sizes of particles [total
suspended particles (TSP), PM≤ 10 μm in aerodynamic diameter (PM10),≤ 10–2.5 μm
(PM10–2.5), and≤ 2.5 μm (PM2. 5)] and infant mortality in a cohort in Seoul, Korea, 2004–
2007. Methods The study includes 359,459 births with 225 deaths. We applied extended …
