Cigarette smoking in Australian schoolchildren.

Six thousand, four hundred and fifty-one schoolchildren who were aged nine to 15 years completed a questionnaire about their patterns of cigarette use, as part of the nation-wide Health and Fitness Survey of Australian Schoolchildren which was conducted in 1985. The survey yielded figures for the prevalence of cigarette smoking by age, sex, socioeconomic status and ethnic origin. It also provided data on the relationship between parental smoking and smoking in children. By the age of 15 years, 32.4% of the girls and 26.0% of the boys in the study sample had smoked at least one cigarette in the seven days before they were surveyed. In some of the age-groups, the average number of cigarettes that were consumed by girl smokers equalled or exceeded that of their male counterparts. There were no significant differences in the prevalence of current cigarette smoking with differences in socioeconomic status. This finding contrasts with the pattern of use in adults. Ethnic origin was a statistically-significant predictor of smoking behaviour in children. Significantly-fewer children of Asian ethnic origin were current smokers. Parental smoking status also appeared to be an important determinant of smoking behaviour in schoolchildren. This influence was more important for girls than for boys, particularly when the mother was a smoker. The over-all findings suggest that many features of the adult pattern of cigarette use are established by the age of 15 years. The findings also supported the trend towards increased cigarette consumption by girls compared with boys that was noted by earlier researchers. These findings should encourage a serious reappraisal of the role of cigarette advertising in the promotion of smoking in young persons.
