Prenatal and early life exposure to particulate matter, environmental tobacco smoke and respiratory symptoms in Mexican children.

ABSTRACT:

Background

Exposure to particulate matter <2.5 μm in diameter (PM_2.5) and environmental tobacco smoke (ETS) are associated with respiratory morbidity starting in utero. However, their potential synergistic effects have not been completely elucidated. Here, we examined the joint effects of prenatal and early life PM_2.5 and prenatal ETS exposure on respiratory outcomes in children.

Material and methods

We studied 536 mother-child dyads in the Programming Research in Obesity, Growth, Environment and Social Stressors (PROGRESS) study in Mexico City. Exposure to PM_2.5 was estimated using residence in pregnancy and child's first year of life with a satellite-based spatio-temporal model. ETS exposure was assessed by caregiver's report of any smoker
