Childhood, adult, and lifelong SHS exposure is associated with more asthma and COPD
Korsbæk N, Landt EM, Dahl M. Second-hand smoke exposure associated with risk of respiratory symptoms, asthma, and COPD in 20,421 adults from the general population. J Asthma Allergy. Published online October 28, 2021. doi:10.2147/JAA.S328748

“Investigators pulled data from a cohort of more than 20,000 adults who participated in the Danish General Suburban Population Study, a cross-sectional study performed in a Danish city between 2010 and 2013.
Investigators examined three exposure groups to determine rates of common respiratory conditions, such as wheezing, severe dyspnoea, coughing on exertion, asthma, and COPD. In all cases, exposure to secondhand smoke increased the odds ratios of having the respiratory condition.
In the case of asthma, the odds ratios (OR) for those with lifelong exposure, adulthood-only exposure, and childhood-only exposure were 1.36 (95% CI, 1.14–1.63), 1.49 (95% CI, 1.09–2.05), and 1.13 (95% CI, 0.99–1.30), respectively. For COPD, the odds ratios were 1.24 (95% CI, 1.03–1.48), 1.25 (95% CI, 0.90–1.74), and 1.09 (95% CI, 0.96–1.24), respectively.
Extrapolating those data, the investigators concluded that 4.3% of population-level cases of asthma and 2.9% of population-level cases of COPD could potentially be attributed to lifelong secondhand smoke exposure.”
