The Effects of Secondhand Smoke Exposure on Allergic Disorder Development
the MPR take:
Few longitudinal studies have evaluated the association between secondhand smoke (SHS) exposure from birth to adolescence, particularly regarding the risk for the development of allergic disorders such as asthma, rhinitis, and eczema. A new longitudinal population-based birth cohort study in the journal Pediatrics followed 4,089 children for 16 years; researchers gathered information on parental smoking habits, lifestyle factors, and symptoms of allergic disorders. Exposure to SHS in utero was linked with an overall elevated risk of developing asthma up to 16 years, but not for rhinitis or eczema. SHS exposure during infancy was associated with an overall elevated risk of asthma, rhinitis, and eczema up to 16 years. The elevated risks with SHS exposure in utero or in infancy for asthma and rhinitis were mainly found in early childhood while the excess risk for eczema was greater at later ages.
OBJECTIVES: To examine the role of prenatal and postnatal second-hand tobacco smoke (SHS) exposure on asthma, rhinitis, and eczema development up to 16 years of age.METHODS: A birth cohort of 4089 children was followed for 16 years. Generalized estimating equations assessed the overall and ...
