Effects of a National Campaign on Youth Beliefs and Perceptions About Electronic Cigarettes and Smoking.

Introduction: Our study assesses the relationship between the exposure of youth to the US Food and Drug Administration's national tobacco public education campaign, The Real Cost, and changes in campaign-focused risk perceptions and beliefs.

Methods: A nationally representative cohort study of youth was conducted from June 2018 to July 2019, consisting of a baseline and one follow-up survey. We performed logistic regressions to examine the association between campaign exposure and beliefs.
