Tobacco use among high school students in Buenos Aires, Argentina.
OBJECTIVE
This study assessed the prevalence and correlates of tobacco use among high school students in Buenos Aires, Argentina.


METHODS
Anonymous, self-administered questionnaires were given to 3909 8th and 11th graders in a stratified random sample of 49 public and private schools. The instrument included items from American surveys, translated and validated among Argentinean teens. Multiple logistic regression analysis was used to estimate possible effects on smoking behavior of environment, students' personal characteristics, and their knowledge, beliefs, and attitudes regarding smoking.


RESULTS
Of 8th and 11th graders, 20% and 43%, respectively, were classified as current smokers. Overall, 29% of males and 32% of females were current smokers. Students attending public schools were more likely to smoke than those in private schools (P < .05). Current smoking was associated with having a best friend who smokes, reporting that more than 50% of friends of the same sex smoke, having positive attitudes and beliefs toward smoking, and having a positive intention to smoke within the next year (all P < .001).


CONCLUSIONS
Over 20% of the 8th graders in our sample were current smokers; prevention efforts must therefore start early.
