Context.— Whether tobacco advertising and promotion increases the likelihood that
youths will begin smoking has important public policy implications.
Objective.— To evaluate the association between receptivity to tobacco advertising
and promotional activities and progress in the smoking uptake process, defined
sequentially as never smokers who would not consider experimenting with smoking,
never smokers who would consider experimenting, experimenters (smoked at least
once but fewer than 100 cigarettes), or established smokers (smoked at least
Design.— Prospective cohort study with a 3-year follow-up through November 1996.
Setting and Participants.— A total of 1752 adolescent never smokers who were not susceptible to
smoking when first interviewed in 1993 in a population-based random-digit
dial telephone survey in California were reinterviewed in 1996.
Main Outcome Measure.— Becoming susceptible to smoking or experimenting by 1996.
Results.— More than half the sample (n=979) named a favorite cigarette advertisement
in 1993 and Joe Camel advertisements were the most popular. Less than 5% (n=92)
at baseline possessed a promotional item but a further 10% (n=172) were willing
to use an item. While having a favorite advertisement in 1993 predicted which
adolescents would progress by 1996 (odds ratio [OR] =1.82; 95% confidence
interval [CI], 1.04-3.20), possession or willingness to use a promotional
item was even more strongly associated with future progression (OR=2.89; 95%
CI, 1.47-5.68). From these data, we estimate that 34% of all experimentation
in California between 1993 and 1996 can be attributed to tobacco promotional
activities. Nationally, this would be over 700000 adolescents each year.
Conclusion.— These findings provide the first longitudinal evidence to our knowledge
that tobacco promotional activities are causally related to the onset of smoking.
