Association between fine particulate matter (PM_2.5) and infant mortality in a North Carolina birth cohort (2003-2015).

ABSTRACT:

Background

While the association between fine particulate matter (PM_2.5) and adult mortality is well established, few studies have examined the association between long-term PM_2.5 exposure and infant mortality.

Methods

We conducted an unmatched case-control study of 5992 infant mortality cases and 60,000 randomly selected controls from a North Carolina birth cohort (2003-2015). PM_2.5 during critical exposure periods (trimesters, pregnancy, first month alive) was estimated using residential address and a national spatiotemporal model at census block centroid. We fit adjusted logistic regression models and calculated odds ratios (ORs) and 95% confidence intervals (CIs). Due to differences in PM_{2 .5} over time, we stratified
