Sex Differences in the Association of E-cigarette and Cigarette Use and Dual Use with Self-reported Hypertension Incidence in US Adults.

This nationally representative cohort study provides the very first evidence of whether there are prospective associations of established e-cigarette and cigarette use and dual use with future hypertension onset among US adult females and males. We found that exclusive cigarette smoking was associated with increased risk of incident hypertension among females, but not males. We observed a trend of a dose-response relationship between e-cigarette use and risk of incident hypertension among female exclusive e-cigarette users or dual e-cigarette and cigarette users. Our study will contribute to understanding the chronic health risks of vaping to prevent the potential long-term e-cigarette use related health burden.
