Background: The prevalence of combusted cigarette (CC) smoking among older adults is stagnant, with 0 declines attributable to e-cigarette (EC) use. Given that normative beliefs are associated with quitting and switching to ECs, we assessed cross-sectional associations between age, CC, and EC descriptive and injunctive norms and potential interactions with tobacco use behavior.
Methods: Data are from people with current, established (≥100 lifetime CCs) CC use (n = 8072) at Wave 5 (2018-2019) of the adult Population Assessment of Tobacco and Health Study. We used adjusted multivariable logistic regressions to model social norms as a function of age (18-24, 25-34, 35-44, 45-54, 55-64, ≥65 years). We also dichotomized age (≥55 vs 18-54) to investigate interactions between age and social norms on past 12-month CC quit attempts and past-month EC use.
Results: Older age was positively associated with pro- and anti-CC norms and anti-EC norms. Significant interactive effects revealed that being advised to quit smoking by a healthcare provider was more strongly associated with CC quit attempts among adults ≥55 years (adjusted odds ratio [aOR] [95% CI]: 2.12 [1.66, 2.71]) than adults <55 years (aOR: 1.63 [1.34, 2.00]). Reporting people close to you use ECs was also more strongly associated with EC use among adults ≥55 years (aOR: 4.37 [3.35, 5.69]) than among adults <55 years (aOR: 3.43 [2.89, 4.08]).
Conclusions: This study identified modifiable risk factors for tobacco use that may be particularly beneficial for older adults. Behavioral and communication interventions that target normative beliefs may maximize smoking cessation, or harm reduction when cessation is not possible.
