  Exposure to secondhand smoke has been associated with numerous health problems in children, including obstructive sleep apnea.

Secondhand smoke exposure may be a risk factor for increased pediatric sleep apnea severity.

Objectives

To assess the association of secondhand smoke exposure (SHSe), quantified by urinary cotinine levels, with severity of obstructive sleep apnea (OSA) in children.

This was a prospective cohort trial including pediatric patients from 3 to 16 years of age with sleep-disordered breathing who underwent a polysomnogram at a tertiary-level children’s hospital in the US in either March 2014 to October 2016 or March 2020 to March 2021.

Urine specimens were analyzed for cotinine, an important metabolite of nicotine. Each child’s caregiver completed a validated SHSe questionnaire. Data were analyzed from February to June 2023.
