Tobacco is responsible for a third of all cancers, as well as a large
proportion of cardiovascular and chronic respiratory diseases. Monitor
ing of the tobacco epidemic is necessary everywhere, in particular in
non-English-speaking countries where until recently no decrease was se
en in tobacco consumption. National population surveys have been condu
cted repeatedly on representative samples of both the adolescent and a
dult French population to evaluate trends in smoking behavior. A decre
ase can be noted in the population of adolescent smokers of both sexes
-from 46% in 1977 to 30% in 1991. Among adults the overall figure is r
ather stable due to contrasting trends, with a general decrease among
men (although not among young men aged 18 to 24) counterbalanced by an
increase among women. Future health education efforts should focus on
women of all ages but should not neglect young men, although the decr
eas observed among girls and boys is promising.
