Background: Premature atherosclerotic cardiovascular disease (ASCVD) is increasing in young adults (<55 years old). While research suggests females who smoke cigarettes have a higher risk of ASCVD than males, studies on the impact of exclusive e-cigarette and dual use on premature ASCVD are limited. This study investigated the association between tobacco use and self-reported premature ASCVD and explored potential sex differences.
Methods: Using pooled data from 480,317 adults (ages 18-54; ∼50 % female) from the 2020-2022 Behavioral Risk Factor Surveillance System from the United States, logistic regression models assessed associations between cigarette and e-cigarette use patterns and self-reported premature ASCVD. Tobacco use categories were defined as: non-use, former use (cigarettes, e-cigarettes), and current use (cigarettes, e-cigarettes) and dual use. Self-reported premature ASCVD was defined as self-reported angina or coronary heart disease, heart attack, or stroke. Weighted analyses were conducted for the overall sample and stratified by sex.
Results: After controlling for potential confounders, former exclusive cigarette (adjusted OR: 1.47 [95 % CI 1.29, 1.67]), current exclusive cigarette (1.68 [1.47-1.94]) and current dual (2.03 [1.69-2.44]) use were associated with higher odds of self-reported premature ASCVD. There was no significant association for e-cigarette use. Sex-specific analyses revealed similar patterns but the magnitude of these associations varied between males and females.
Conclusion: Both sexes showed higher odds of self-reported premature ASCVD for dual and exclusive cigarette use. Although the cross-sectional design precludes causal inferences, the findings suggest comprehensive tobacco cessation programs tailored to diverse use patterns are needed to reduce the burden of premature ASCVD.
