Odds ratios calculated using multivariable logistic regression* for the association between e-cigarette use and sociodemographic factors, by risk factor

Risk factorOR (95% CI)p
Male1.7 (1.2–2.3)0.002
Respondent knew that smoking can cause lung cancer0.2 (0.02–1)0.05

Respondent reported excellent or good stress level0.6 (0.4–0.9)0.003
  • Note: CI = confidence interval, e-cigarette = electronic cigarette, OR = odds ratio. OR > 1 suggests a positive association between e-cigarette use and risk factor.
