Menée aux Etats-Unis sur la période 2014-2018 par entretiens auprès de 155 556 participants de plus de 18 ans, cette étude analyse l'évolution de la prévalence de l'usage de la cigarette électronique, en fonction des statuts sociodémographique et tabagique
Prevalence of e-cigarette use among US adolescents substantially increased from 2017 to 2018. Whether prevalence also increased among young adults (18-24 years)—a population with high vaping rates and vulnerability to nicotine dependence and other health consequences of nicotine exposure—is unknown.Prevalence of current e-cigarette use decreased among all US adults between 2014 and 2016. This study examined 2014-2018 trends and the 2017-2018 biannual change in prevalence of e-cigarette use in US adults of different ages. Among young adults, e-cigarette use trends by sociodemographic and smoking status were also examined.
