Rates of electronic cigarette use among adults with a chronic mental illness

Abstract

Introduction: Electronic cigarette (e-cig) use has increased dramatically over the past decade, rates of e-cig use among those with a chronic mental illness has largely been unexplored. Exploring this relationship for adults with a mental illness is necessary when examining the health needs of this population.

Methods: Data from the 2016 National Health Interview Survey (NHIS) was used to explore associations between e-cig use and chronic mental illness. E-cig use was explored in two different contexts, having tried an e-cig at least once and current e-cig use. Chronic mental illness was categorized as depression, anxiety, emotional disorder, or ADD, bipolar, schizophrenia, other disorder.

Results: Rates of ever trying an e-cig and current e-cig use were higher among those with a chronic mental illness. Complex logistic regressions suggested having a chronic mental illness significantly increases the likelihood of both trying an e-cig and being an e-cig user.

Conclusions: Increased likelihood of e-cig use in chronic mental illness supports previous findings. This may be due to perceptions that e-cigs are less harmful and they provide ways of socially connecting with others.

Implications: Current knowledge surrounding e-cig use in this population is lacking. The 2016 NHIS allows for a nationally representative prediction of e-cig use in this population. This data is relevant in monitoring potential harm caused by e-cigs, in addition it may be helpful when assessing the value of e-cigs as a smoking cessation tool for those with a mental illness.
