Sex-specific associations of cigarettes and e-cigarettes use with self-reported premature atherosclerotic cardiovascular disease among adults aged 18-54 in the United States.

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.
