PRS16 - Predictors Of Electronic Cigarette Use Among Individuals With Asthma

Abstract

This study assessed predictors of electronic cigarette use among individuals with asthma, from nationally representative sample. Using the 2014 National Health Interview Survey (NHIS), we identified (N = 8,154) survey participants, aged ≥18 years. Weighted adjusted multivariable logistic regression was used to assess predictors of e-cigarette use. The prevalence of e-cigarette use was 16.57% among study sample. Compared to never smokers, current cigarette smokers had 35.07 times (95% CI: 27.17-45.25) and former cigarette smokers had 6.38 times (95% CI: 4.95-8.23) higher odds of using e-cigarettes. Furthermore, compared to individuals aged ≥ 65 years, those aged 18-24 (aOR = 8.62; 95% CI: 5.63-13.21), 25-24 (aOR = 5.99; 95% CI: 4.05-8.86), 35-49 (aOR = 3.52; 95% CI: 2.45-5.04), and 50-64 years (aOR = 2.19; 95% CI: 1.53-3.13) all had higher odds of using e-cigarettes. Males, compared to females, had 1.20 times (95% CI: 1.00-1.45) higher odds of use. Both Hispanics (aOR = 0.72; 95% CI: 0.53-0.97) and Non-Hispanic Blacks (aOR = 0.26; 95% CI: 0.19-0.35) had lower odds compared to Non-Hispanic Whites, however, only Non-Hispanic Others (e.g. multiple race/ethnicity) had 1.52 times (95% CI: 1.03-2.42) higher odds of use. Compared to graduate students, only college students, had significantly higher odds of using e-cigarettes (aOR = 1.53; 95% CI: 1.07-2.18). Additionally, current alcohol users, compared to lifetime abstainers, had 2.37 times (95% CI: 1.75-3.97) higher odds of e-cigarette use. Self-reported health was a significant predictor of usage; those in very good/good health (aOR = 1.65; 95% CI: 1.27-2.14) and fair/poor health (aOR = 2.21; 95% CI: 1.60-3.04) had higher odds of using e-cigarettes, compared to self-reported excellent health. Self-reported cigarette smokers and young adults had the highest odds of e-cigarette use. Future research should determine factors associated with initiation and impact of e-cigarettes on wellbeing and better understand e-cigarettes for future interventions and health promotion activities.
