15 Oct E-cigarette use associated with increased risk of developing COPD, chronic bronchitis, emphysema and asthma.
Acknowledging the recent rise in popularity of e-cigarettes or vaping devices as ‘healthy alternatives’ to tobacco cigarette smoking, Xie et al.1 have recently published a valuable longitudinal study into the adverse outcomes of e-cigarette use on respiratory health, adding to the growing literature about the harms of vaping.
Acknowledging the recent rise in popularity of e-cigarettes or vaping devices as ‘healthy alternatives’ to tobacco cigarette smoking, Xie et al.1 have recently published a valuable longitudinal study into the adverse outcomes of e-cigarette use on respiratory health, adding to the growing literature about the harms of vaping. Over 5 years, Xie et al. followed 21,618 participants in the Population Assessment of Tobacco and Health (PATH) study2, surveying them every year about their smoking habits, e-cigarette usage and any incident diagnoses of respiratory conditions.
They found significant associations between use of e-cigarettes, either formerly or currently, with a risk of developing COPD, chronic bronchitis, emphysema, and asthma. These associations were found among diverse populations, in all age-groups, among smokers and non-smokers, and in both males and females, even when the participants at the start of the study rated their own health highly.
While unable to establish confident causation between e-cigarettes and incident respiratory conditions, Xie et al. were able to corroborate the findings from several systematic reviews and meta-analyses of less impactful cross-sectional studies to establish a strong associative link between the two3-9. Their findings provide much-needed longitudinal data into a largely under-studied field.
