Association between e-cigarette use behaviors and perceived harmfulness of e-cigarettes and anxiety/depression symptoms among Black/African American Adults.

Black/African American adults are at greater risk of experiencing negative health outcomes stemming from tobacco use, yet little research has examined e-cigarette use behavior in the Black/African American adult-only population. We examined the association between e-cigarette use behaviors (never, former, and current use) and perceived harmfulness of e-cigarette use and anxiety/depression symptoms among Black/African American adults. This cross-sectional study was a secondary analysis of nationally representative data from the 2011-2020 Health Information National Trends Survey (n = 6,268). Multinomial logit models were used to examine differences in e-cigarette use behaviors (reference group = never used e-cigarettes), given the risk factors named above. The prevalence of former and current e-cigarette use among Blacks/African Americans was 11.65 % and 3.52 %, respectively. There was a significant interaction between the perceived harmfulness of e-cigarette use and anxiety/depression. Moderate or severe anxiety/depression symptoms were associated with a higher likelihood of current e-cigarette use, but not former e-cigarette use. Compared to individuals who perceived e-cigarette use as less harmful than smoking cigarettes, those who perceived e-cigarette use as just as harmful were less likely to be current e-cigarette users. Those who perceived e-cigarette use as more harmful or were uncertain were less likely to be former or current e-cigarette users. Anxiety/depression and perceived harmfulness of e-cigarette use and their interactions were significantly associated with e-cigarette use behaviors. These findings provide an opportunity to offer tobacco cessation and prevention interventions to subgroups in this population and inform development of content for the same.
