ethnic differences in smoking susceptibility among US youth
Examine racial/ethnic differences in smoking susceptibility among US youth abstract
nonsmokers over time and age.
METHODS: We used nationally representative samples of youths who never tried cigarettes
(N = 143 917; age, 9–21, mean, 14.01 years) from National Youth Tobacco Survey, 1999
to 2014. We used time-varying effect modeling to examine nonlinear trends in smoking
susceptibility adjusted for demographics, living with smokers, and exposure to tobacco
advertising.
RESULTS: Compared with non-Hispanic whites (NHWs), Hispanics were more susceptible to
smoking from 1999 to 2014 (highest adjusted odds ratio [aOR], 1.67 in 2012). Non-Hispanic
blacks were less susceptible to smoking than NHWs from 2000 to 2009 (lowest aOR, 0.80
in 2003–2005). Non-Hispanic Asian Americans were less susceptible to smoking from 2000
to 2009 (aOR, 0.83), after which they did not differ from NHWs. Other non-Hispanics were
more susceptible to smoking than NHWs from 2012 to 2014 (highest aOR, 1.40 in 2014).
Compared with NHWs, non-Hispanic blacks and other non-Hispanics were more susceptible
to smoking at ages 11 to 13 (highest aOR, 1.22 at age 11.5) and 12 to 14 (highest aOR, 1.27 at
age 12), respectively. Hispanics were more susceptible to smoking throughout adolescence
peaking at age 12 (aOR, 1.60) and age 16.5 (aOR, 1.46). Non-Hispanic Asian Americans were
less susceptible to smoking at ages 11 to 15 (lowest aOR, 0.76 at ages 11–13).
CONCLUSIONS: Racial/ethnic disparities in smoking susceptibility persisted over time among
US youth nonsmokers, especially at ages 11 to 13 . Interventions to combat smoking
susceptibility are needed.
