Fine particulate matter and nonaccidental and cause-specific mortality: Do associations vary by exposure assessment method?

ABSTRACT:

Background

There is considerable heterogeneity in fine particulate matter (PM_2.5)-mortality associations between studies, potentially due to differences in exposure assessment methods. Our aim was to evaluate associations of PM_2.5 predicted from different models with nonaccidental and cause-specific mortality.

Methods

We followed 107,906 participants of the Nurses' Health Study cohort from 2001 to 2016. PM_2.5 concentrations were estimated from spatiotemporal models developed by researchers at the University of Washington (UW), Pennsylvania State University (PSU), and Harvard TH Chan School of Public Health (HSPH). We calculated 12-month moving average concentrations and we used time-varying Cox proportional hazard ratios (HRs).
