OBJECTIVES:The purpose of this study was to examine whether youth participation in tobacco promotion campaigns is associated with susceptibility to tobacco use. METHODS:Data were collected from telephone interviews of a national random sample of 1047 adolescents 12 to 17 years of age. RESULTS:A proportional odds model was used to estimate the effects of age, gender, presence of a tobacco user in the household, awareness of tobacco promotions, knowledge of a young adult or adolescent friend owning a promotional item, participation in tobacco promotions, and receipt of free tobacco samples or direct mail from tobacco companies on susceptibility to tobacco use. All of the covariates, except for receiving direct mailings and knowing a young adult friend who owned a promotional item, were significantly associated with susceptibility. CONCLUSIONS:There is a strong association between an awareness of and involvement with tobacco promotions and being susceptible to tobacco use or a user of tobacco products.
