Gender Difference in the Association Between E-Cigarette Use and Depression among US Adults.

Abstract

ObjectivesThe objective of this study was to determine the association between e-cigarette use and depression and examine how this association is different by gender among US adults.MethodsData from the 2017 Behavioral Risk Factor Surveillance System and Selected Metropolitan/Micropolitan Area Risk Trends was used, and included 174,351 of 230,875 US adults aged 18 years and older. Data were analyzed using the multivariate logistic regression models.ResultsAfter adjusting for age, race, education, income, marital status, employment status, smoking status, and physical activity, firstly, “current daily e-cigarette users” (AOR = 2.487, p < 0.001), “current non-daily e-cigarette users” (AOR = 1.623, p < 0.001), and “former e-cigarette users” (AOR = 1.573, p < 0.001) were associated with increased odds of depression compared with “never e-cigarette users.” Secondly, women were associated with increased odds of depression compared with men (AOR = 1.797, p < 0.001). Finally, male “current daily e-cigarette users” (AOR = 1.366, p < 0.01) were associated with increased odds of depression compared with female “never e-cigarette users.”ConclusionThus, even though women tend to be more vulnerable to depression compared with men, e-cigarette use was positively associated with depression among both men and women.
