Absolute and relative e-cigarette harm perceptions among young adult lesbian and bisexual women and nonbinary people assigned female at birth.

purposeYoung adult lesbian and bisexual women report considerable e-cigarette disparities, which may be attributed to low harm perceptions. No studies have assessed differences in e-cigarette harm perceptions in this group, nor which factors might be intervention targets to influence harm perceptions. MATERIALS AND

methodsWe investigated differences in and modifiable correlates of e-cigarette harm perceptions among young adult lesbian and bisexual women and non-binary people assigned female at birth. Young adult women and non-binary people assigned female at birth, aged 18-30 years old, and who self-identified as lesbian or bisexual (N = 471) reported absolute and relative harm perceptions of e-cigarettes to health in an online survey. We modeled associations between harm perceptions and individual, interpersonal, and contextual factors.

resultsBisexual (vs. lesbian) participants perceived higher absolute harm of e-cigarettes (Mean (M) = 7.61 vs M = 7.09, p = .03). Participants rated e-cigarettes as slightly less harmful than cigarettes, and there was no statistically significant difference by sexual orientation (Bisexual: M = 4.84 vs Lesbian: M = 4.36). In multivariable models, bisexual (vs. lesbian) participants and Hispanic/Latinx and Other race (vs. non-Hispanic White) participants reported higher absolute and relative e-cigarette harm perceptions. Greater sexual identify affirmation and greater perceived stress were associated with higher absolute and relative e-cigarette harm perceptions.

conclusionsE-cigarette harm perceptions vary vis-à-vis individual-level factors. Self-identification as bisexual or minoritized race/ethnicity, greater sexual identity affirmation, and greater perceived stress was associated with increased harm perceptions. Understanding variations may inform targeted health communications to reduce e-cigarette use disparities.
