[The results of educational anti-smoking measures at the primary school level (author's transl)].
A retrospective study was made from a self-administered questionnaire distributed to 4,166 pupils aged 15 to 18, attending "Bas-Rhin" high schools, in Spring, 1979. The results demonstrate the relative effectiveness of educational anti-smoking measures when information is given to specific age groups. Information given at the primary school level results in a proportionately and significantly lower number of smokers; there was also a tendency both to smoke fewer cigarettes per day, and to choose brands having lower tar and nicotine levels. These pupils also left a greater portion of the cigarette unsmoked, i.e. they left longer cigarette butts. In addition, the number of pupils who had never smoked was greater in those groups who received information at the primary school level; and the number of ex-smokers (those who had given up smoking for at least one year) was also greater. The results emphasize the effectiveness and importance of public health measures carried out in young children.
