Antepartum Exposure to Greenness, Air Pollution, and Temperature and Outcomes of Preterm Infants.

ABSTRACT:

Importance

Existing evidence shows that the environment is a risk factor in preterm birth. However, more evidence is needed about the association between environmental exposures and outcomes of preterm birth.

Objective

To examine the association of antepartum exposure to individual and combined indices of greenness, air pollution, and extreme temperatures with outcomes of preterm infants.

Design, setting, and participants
