E-cigarette use linked to cigarette initiation in adolescents

E-cigarette use linked to cigarette initiation in adolescents

(HealthDay)—Electronic cigarette use is associated with an increased risk for cigarette initiation and use in adolescents, according to a study published online Feb. 1 in JAMA Network Open.

Kaitlyn M. Berry, M.P.H., from the Boston University School of Public Health, and colleagues examined data from waves 1 to 3 of the Population Assessment of Tobacco and Health Study (2013 to 2016) for 6,123 adolescents aged 12 to 15 years who had never used , e-cigarettes, or other tobacco products at wave 1.

The researchers found that at wave 3, cigarette use was higher among previous users versus adolescents with no prior tobacco use (20.5 versus 3.8 percent). Compared with no prior use, prior e-cigarette use correlated with significantly increased odds of ever cigarette use and current cigarette use (odds ratios, 4.09 and 2.75, respectively); the odds were similarly increased with prior use of other (odds ratios, 3.84 and 3.43, respectively). Low-risk adolescents had a stronger association of prior e-cigarette use with cigarette initiation (odds ratio, 8.57). Among youth aged 12 to 15 years, from 2013-2014 to 2015-2016, 21.8 and 15.3 percent of new cigarette ever use and current cigarette use, respectively, may be attributable to prior e-cigarette use, according to the researchers.

"These findings strengthen the rationale for aggressive regulation of youth access to and marketing of e-cigarettes to achieve future decreases in the prevalence of cigarette use among youths," the authors write.
