Association of early pregnancy warm season exposure and neighborhood heat vulnerability with adverse maternal outcomes: A retrospective cohort study.

ABSTRACT:

Introduction

Rising ambient temperatures threaten vulnerable populations such as pregnant women, with urban populations bearing a greater risk due to the urban heat island effect. Here, we assessed the independent effects of trimester-specific warm season exposure during pregnancy and neighborhood heat vulnerability on maternal outcomes, including gestational diabetes, hypertensive disorders of pregnancy, genitourinary infections, and operative delivery.

Methods

This retrospective study analyzed 819 participants from the Stress in Pregnancy Study (2009-2014), a longitudinal birth cohort study in New York City. Generalized linear models examined associations between trimester-specific warm season exposure, New York City Heat Vulnerability Index (ranging 1-5), and adverse mate
