RESUMO
The objective of this study is to compare the prevalence of smoking among young students of the area of La Garrotxa between 1982 and 1986. Two surveys were made, following the same methodology, interviewing two samples of student population 13 to 25 years old. The total number of interviewed students were 1,039 in 1982 and 1,133 in 1986. The smoking prevalence was lower in 1986 than in 1982, decreasing from 55% to 35%. This difference was due to a decrease in the prevalence of those younger than 17 in both sexes and remained stable after adjusting for age, sex and school. The initial age for experimental smoking was delayed by 1 year from 1982 to 1986. The proportion of smoker parents was not different between both periods. We conclude that smoking habit has decreased in younger people, and this is probably due to a delay in the age of smoking initiation.
