Merianos AL, et al. - In this secondary cross-sectional analysis of Population Assessment of Tobacco and Health Study Wave 2 (2014–2015) including 2,198 asthmatic adolescents, researchers examined the link between secondhand smoke exposure (SHSe) and asthma symptoms, medication use, and Emergency Department (ED)/urgent care (UC) utilization by using logistic regression models and Poisson regression models. An increased risk of reporting shortness of breath and harder to exercise, wheezing, wheezing disturbing sleep, wheezing during/after exercise, wheezing limiting speech, dry cough at night, and asthma symptoms disturbing sleep was observed among participants with SHSe ≥1 hour in the past 7 days. Also, asthma medications, including steroids, oxygen therapy, and controlling medications were more likely to be consumed by asthmatics with SHSe ≥1 hour. An increased risk of higher ED/UC visits for asthma was noted in those who lived with a smoker and had home SHSe. Overall, findings call for SHSe reduction efforts for asthmatic adolescents.
