title: Adolescent Electronic Cigarette Use: Associations With Conventional Cigarette and Hookah Smoking.
abstract: BACKGROUND
  The emerging trends and rapid growth of electronic cigarettes (e-cigarettes) among adolescents are being monitored closely. The trends are critical as policy to prevent uptake among adolescents is considered. The purpose of this study is to describe the prevalence of e-cigarette use and potential correlates for use. Associations between e-cigarettes, cigarettes, and hookah are assessed.
  
  
  METHODS
  This study used data from the 2013 Florida Youth Tobacco Survey. Prevalence estimates were calculated in 2014 and differences were determined based on CIs. Adjusted logistic regression models were used to identify correlates of e-cigarette use among participants based on demographic and other tobacco products used.
  
  
  RESULTS
  There were no sex differences in middle school, whereas male high school students reported higher use than their female counterparts. Cigarette smoking and hookah use were significantly associated with ever and current e-cigarette use among both middle and high school students.
  
  
  CONCLUSIONS
  Although e-cigarettes are being assessed as a potential replacement product for traditional tobacco, evidence from this study indicates the possibility of multiple product use among adolescents. E-cigarettes are not only associated with traditional cigarettes, but also with hookahs, a similar emerging product that offer tobacco flavors that may appeal to adolescents. Notably, many e-cigarette users also reported no cigarette or hookah use.
