Abstract

This cohort study uses data from the New Hampshire Birth Cohort Study to assess maternal glycemia and newborn size among pregnant women who use wood-burning stoves in their New England homes.

Highlights

Wood stove use has increased in the United States, with over 12 million households using wood as a primary or supplemental heat source.[1]
We used a χ2 test for all categorical variables and a t test for all continuous variables. d Calculated as weight in kilograms divided by height in meters squared. e Impaired glucose tolerance or gestational diabetes. f Per the 2011-2015 American Community Survey. g Primary or secondary road in 2015 topologically integrated geographic encoding and referencing/ Line database. h Less than the 10th percentile of birth weight for gestational age z score
Women who used wood stoves in the third trimester had 1.81 times the odds of having an small for gestational age (SGA) infant, and their infants had a 0.17 unit lower birth weight for gestational age (BWGA) z score

Summary

Introduction

Wood stove use has increased in the United States, with over 12 million households using wood as a primary or supplemental heat source.[1]. We evaluate the association of wood stove use during pregnancy with maternal glycemia and infant birth size in a large cohort in northern New England.
