| description | Background
Adolescent electronic cigarette (EC) use in relation to exposure to advertising
has rarely been studied outside Western settings. We investigated the exposure
to EC advertising in Hong Kong adolescents and its association with the intention
to use ECs in never users.
Methods
In 2014/15, 40202 Secondary 1-6 (US grade 7-12) students
(mean age 14.9, standard deviation 1.8; 51.5% boys) from 92 randomly selected schools completed
an anonymous questionnaire. Exposure to messages directly or indirectly
promoting ECs through each of 12 sources in the past 30 days, and the intention
to use ECs in the next 12 months or when a good friend offered an EC were
reported. Weighted prevalence of exposure to EC advertising was calculated.
Logistic regression yielded adjusted odds ratios (AORs) of intention to use ECs
for the exposure to EC advertising (versus no exposure to any source) in never EC users.
Results
In all students, 38.0% (95% confidence interval [CI] 37.5%-38.5%) were exposed to
EC advertising, most commonly through television (15.1%). In never EC users
(n=36274), any exposure to EC advertising was associated with an AOR (95% CI)
of 1.50 (1.23-1.84) for the intention to use ECs, with increasing AORs for more
sources of exposure (p for trend< 0.001) and an AOR of 2.20 (1.55-3.12) for 4 sources or more. Exposure through
social networking sites (prevalence: 9.9%; AOR 2.58, 95% CI 2.03-3.27), video
sites (4.4%; 2.56, 1.84-3.55) and other websites (2.5%; 2.26, 1.45-3.53) had
the strongest associations with the intention to use ECs.
Conclusions
Four in 10 Hong Kong adolescents were exposed to EC
advertising through different sources. The exposure was dose-dependently associated
with an intention to use ECs in never users. Banning EC advertising may prevent
EC use in adolescents. |
