title: [The smoking habit in schoolchildren].
abstract: Smoking habit was studied in 2776 school boys aged 9-16 years from Zagreb and surrounding area. In a total sample, 422 (15.2%) examinees were smokers. The most of the smokers smoke 1 to 5 cigarettes daily and the most frequent duration of smoking is 1 to 3 years (62.6%). Boys started smoking already at the preschool age. Most of them started smoking during the first four years of primary school (54.1%). Statistical analysis did not show association between intensity and duration of smoking. Smoking intensity increases significantly with age. Significantly larger frequency of cough was found in smokers compared to nonsmokers (p < 0.0001). However, there is no significant association between cough and duration and intensity of smoking. Significantly larger number of fathers and other members of the family who smoke was found for boys smokers than for boys nonsmokers (p < 0.0001). Intensity of smoking and age of starting smoking in school children were independent of smoking status of the family members.
