[Evaluation of the effect of a lecture and film on smoking on the attitude of students toward smoking].

Within the activities of biology class four pupils conducted an acclaimed poll of all the classes of two elementary schools on the experience with smoking tobacco and the attitude towards smoking and smokers. The investigation was supplemented with the same poll of six classes of the high school center. By processing the answers of 1086 pupils, data was received that pupils tried smoking from 18.6 in the younger grades to 61.7% among high-school students. Projecting the wish towards smoking when they grow up ranges from 8.2 over 14.5 to 6% with the older pupils. But beside these opposite tendencies the number of those who still "light a cigarette" increases from 4% over 7-8 to 23.3% with age. Less than 10% of the pupils from the younger grades has shown that they like smokers, but the attractiveness of the smoking style increases with age. Thus, the proportion of those who do not like smokers and rooms filled with smoke decreases from 95% with the younger pupils to 45% among high-school students. Between the two schools there is a difference of proportion in the replies to the questions asked which is significant at the level of 0.1%. But the distribution of proportions according to the age of those who still "light a cigarette", as well as of those who want to smoke when they grow up coincides with the creating of two maximums: with the youngest pupils and with the highschool students. The testing concerning the influence of the lecture and film on the attitude towards smokers did not reach a 5% level of significance (x2 = 5.19).
