Ambient Temperature and Stillbirth: A Multi-Center Retrospective Cohort Study.

ABSTRACT:

Background

Climate change is expected to have adverse health effects, but the association between extreme ambient temperatures and stillbirth is unclear.

Objectives

We investigated acute and chronic associations between extreme ambient temperatures and stillbirth risk, and estimated the attributable risk associated with local temperature extremes in the United States.

Methods

We linked 223,375 singleton births ≥23 weeks of gestation (2002–2008) from 12 U.S. sites to local temperature. Chronic exposure to hot (>90th percentile), cold (<10th percentile), or mild (10th–90th percentile) temperatures was defined using window- and site-specific temperature distributions for three-months preconception, first and second trimester, and whole-pregnancy averages. For acute expos
