Background. Community dental clinics are good settings for smoking interven
tion. The aim here was to put forward a strategy for preventing adolescent
smoking by means of a brief intervention.
Methods. A total of 2,586 12-year-olds participated in this follow-up study
. They were asked upon arrival for their annual routine dental examination
to complete a smoking questionnaire and were randomly assigned to either th
e intervention group or the usual care control group according to the last
digit of their date of birth (odd or even). The intervention comprised annu
ally inquiring about smoking, showing photographs of the harmful effects of
smoking on the teeth, allowing participants to examine their own mouth wit
h a mirror, and finally counselling them in accordance with their answer to
the question on smoking habits. The smoking status reported was not verifi
ed by other means.
Results. The prevalence of smoking at the end of the 2-year follow-up was 1
.8.1.%, in the intervention group and 20.8% among the controls. However, no
statistically significant differences between groups were found.
Conclusions. These results reflect the difficulties of achieving successful
results with long term smoking cessation programs with adolescents in unst
able conditions. (C) 1999 American Health Foundation and Academic Press.
