Proportion of middle and high school current (past 30-day) cigarette smokers reporting a usual cigarette brand,* by advertising medium and status of exposure to cigarette and/or electronic cigarette ads† — National Youth Tobacco Survey, United States, 2015§
* Outcome was dichotomized as 0 or 1. Persons who reported having a specific brand they usually smoked (“American Spirit,” “Camel,” “GPC, Basic, or Doral,” “Kool,” “Lucky Strike,” “Marlboro,” “Newport,” “Parliament,” “Virginia Slims,” or “Some other brand not listed here”) were coded as 1. Those who responded, “I did not smoke a usual brand” were coded as 0. Responses of “Not sure” or “I did not smoke a cigarette in the past 30 days” were excluded.
† Separate questions were asked for electronic cigarettes and regular cigarettes in relation to exposure to pro-tobacco ads on the different media sources (Internet, newspapers/magazines, retail stores, and TV/movies). For both electronic cigarettes and regular cigarettes, respondents’ ad exposure status was coded on each medium as either: 1 = exposed (responses of “Sometimes,” “Most of the time,” and “Always”) or 0 = nonexposed (“Never,” “Rarely,” or those who indicated not using the assessed medium).
§ The questions on exposure to both electronic cigarette and regular cigarette ads were asked only in 2015.
