Influence of host and environmental factors on wheezing severity in infants: findings from the <scp>PARIS</scp> birth cohort

Abstract

Whilst risk factors for wheeze before 18 months of age are factors related to infections, indoor air pollution, and being overweight, the severity of wheeze is mainly due to the atopic status of the child. We suggest that atopy should be further considered in the assessment of wheezing severity in infants.
