Abstract

Background: Tobacco use presents increased risks for individuals with weakened immune systems (WIS). We investigated the association between cigarette and electronic nicotine delivery systems (ENDS or e-cigarettes) use and WIS in US adults using data from the 2021–2022 National Health Interview Survey. Methods: Data from 57,133 adults were analyzed, focusing on WIS prevalence due to health conditions, prescriptions, or both. Cigarette and ENDS use were categorized as never, former, or current. Weighted multivariable regression models adjusted for demographics and other health conditions to assess associations between tobacco use and WIS. Results: Among US adults, 4.3% had prescription-related WIS, 4.6% had health condition-related WIS, and 7% had WIS due to either reason. Adjusted results from multivariable regression models indicated that adults with WIS due to health conditions were more likely to be current (AOR = 1.21, 95%CI: 1.05–1.40) and former (AOR = 1.25, 95%CI: 1.11–1.39) cigarette smokers compared to counterparts without WIS. Adults with WIS due to prescriptions were more likely to be former cigarette smokers (AOR = 1.19, 95%CI: 1.06–1.34). Those with WIS for any reason were more likely to be current (AOR = 1.19, 95%CI: 1.05–1.35) and former (AOR = 1.24, 95%CI: 1.13–1.36) cigarette smokers. Adults with WIS due to health conditions (AOR = 1.23, 95%CI: 1.06–1.41) or any reasons (AOR = 1.19, 95%CI:1.05–1.34) were more likely to be former ENDS users compared to those without WIS. Conclusions: In this nationally representative study, we found a notable link between cigarette and ENDS use with WIS, particularly among those with health condition-related or prescription-related WIS, underscoring the importance of addressing tobacco use in this vulnerable population. © 2025 Elsevier B.V., All rights reserved.
