Introduction:
Although tobacco product transitions have been characterized in the general population, few studies have examined use in individuals with established cardiovascular disease (CVD).
Methods:
We examined tobacco use prevalence, and longitudinal patterns of tobacco product transitions in adult respondents (≥18 years) of the 2013-2014 (Wave 1) through 2016-2018 (Wave 4) Population Assessment of Tobacco and Health Study. Analysis was restricted to adults with prevalent CVD. Prevalent CVD was defined based on self-report at Wave 1 to the question from a health professional if she/he had: 1) a heart attack, 2) heart failure, 3) a stroke, or 4) some other heart condition. Factors associated with tobacco use (cigarette, e-cigarette, cigar, pipe tobacco, hookah, smokeless, dissolvable, or snus) and tobacco product transitions were investigated using logistic regression.
Results:
At Wave 1, 28.8% reported tobacco use among adults with CVD, the most commonly product was cigarettes (82.8%), followed by use of any type of cigar (49%) and e-cigarette use (23.2%), including 5.4% reporting dual use of cigarettes and e-cigarettes. E-cigarette use without concurrent cigarette use was uncommon (1.1%). Young male with lower level of education and lack of knowledge about the association between smoking and heart disease, were associated with tobacco use. Transition rates reported between Waves 1 and 4 demonstrate decreased cigarette use over time, with increased use of e-cigarette but less dual use. Male with prevalent CVD were less likely to use e-cigarettes compared to female (OR = 0.5, 95% CI: 0.4 - 0.8).
Conclusions:
Despite known harmful cardiovascular effects, almost a quarter of adults with prevalent CVD smoke cigarettes and few are quitting smoking.
