Prenatal exposure to perceived stress, maternal asthma, and placental size.

ABSTRACT:

Introduction

Prenatal exposure to stress has been associated with poor pregnancy outcomes, yet evidence linking stress and placental size is limited. Asthma is associated with worse pregnancy outcomes and women with asthma may be more susceptible to stress. Using the asthma-enriched B-WELL-Mom cohort, we examined the association between perceived stress and placental size.

Methods

Placental measures of weight, length, width, and thickness were available for 345 women (262 with asthma) via placental pathology report. Perceived Stress Scale (PSS) scores were obtained in each trimester of pregnancy and categorized into quartiles (low quartile as reference). For associations between PSS and placental size, generalized estimating equations adjusted for maternal and infant factors
