Pollen exposures in pregnancy and early life are associated with childhood asthma incidence.

ABSTRACT:

Background

Pollen exposure is an environmental risk factor for asthma symptoms and allergic reactions in children. The extent to which pollen exposure in pregnancy and the first year of life influences the development of childhood asthma and rhinitis is not fully understood.

Objective

We aimed to investigate early life exposures to pollen with childhood asthma and rhinitis at age 6 in a longitudinal birth cohort of the United Kingdom.

Methods

In this retrospective cohort study, via logistic regressions, we analyzed the associations between pollen exposures in pregnancy and the first year of life with childhood asthma and rhinitis.

Results

Higher pollen exposure accumulated during pregnancy and during the first year of life both associated with an increased odds
