Cigarette smoking in Australian schoolchildren

Area of Science:

• Public Health
• Adolescent Health
• Epidemiology

Background:

• Cigarette smoking remains a significant public health concern among adolescents.
• Understanding adolescent smoking patterns is crucial for developing effective prevention strategies.
• Previous research indicated a rising trend in smoking among young females.

Purpose of the Study:

• To investigate the prevalence and patterns of cigarette smoking in Australian schoolchildren aged 9-15 years.
• To examine the influence of socioeconomic status, ethnic origin, and parental smoking on adolescent smoking behavior.
• To identify early indicators of adult smoking patterns in young people.

Main Methods:

• A cross-sectional survey of 6,451 schoolchildren aged 9-15 years was conducted in 1985.
• Data on cigarette use, age, sex, socioeconomic status, ethnic origin, and parental smoking habits were collected via questionnaire.
• Statistical analyses were performed to determine prevalence and significant predictors of smoking behavior.

Main Results:

• By age 15, 32.4% of girls and 26.0% of boys reported smoking in the past week.
• Girls' average cigarette consumption equaled or exceeded boys' in some age groups.
• Ethnic origin (fewer Asian smokers) and parental smoking (especially maternal) were significant predictors of adolescent smoking.

Conclusions:

• Adolescent smoking patterns, including increased female consumption, mirror adult trends and are established by age 15.
• Parental smoking and ethnic background are key determinants of smoking behavior in schoolchildren.
• Findings necessitate a re-evaluation of cigarette advertising's role in youth smoking initiation.
