Smoking prevalence - adolescents | National Cancer Control Indicators

Published

07 Sep, 2022

Tobacco use is the single largest cause of cancer globally and the predominant cause of lung cancer.¹ Smoking prevalence among adolescents is an important indicator to target in cancer prevention, because cigarette smoking can become established in adolescence.²

About this measure

In 2015, tobacco was the leading cause of cancer in Australia.^{3, 4} About 90% (Australian men) and 65% (Australian women) of lung cancers are attributable to tobacco smoking.⁵ It is projected that in 2021, 7,460 males and 6,350, females will be diagnosed with lung cancer, and it will be the leading cause of cancer death in Australia.⁴ Tobacco smoking also causes cancers of the oral cavity, pharynx, nasal cavity and accessory sinuses, larynx, oesophagus, stomach, pancreas, colon and rectum, liver, kidney, ureter, bladder, cervix and ovary, and myeloid leukaemia.¹ A positive association between tobacco smoking and female breast cancer has also been reported by the International Agency for Research on Cancer (IARC) and this finding is supported by a meta-analysis of nearly 32,000 breast cancer cases.^{1, 5} The risk of developing lung cancer from tobacco smoking has been shown to increase with duration of smoking and the numbers of cigarettes smoked per day. Notably, most smokers are reported to have commenced using tobacco as adolescents and young people who begin to smoke at an earlier age are more likely to develop long-term nicotine addiction.²

These measures show the proportions of Australian secondary school students aged 12-17 years reporting that they have never smoked and those reporting cigarette smoking on a daily basis. Data are also shown for the number of 15-year-old secondary school students reporting smoking at least once in the last 30 days; this is provided for comparison with international measures of adolescent smoking.

Current status

In 2017, 82% of persons (82% of males and 83% of females) aged 12-17 years reported that they had never smoked, and only 1% of persons (1% of males and 1% of females) aged 12-17 years reported smoking on a daily basis.⁶

Among 15-year-old respondents, 9% of persons (10% of males and 8% of females) reported that they had smoked within the last 30 days.⁶

Aboriginal and Torres Strait Islander peoples

In 2017, 70% of Aboriginal and Torres Strait Islander peoples aged 12-17 years reported that they had never smoked and 14% reported that they had smoked within the last 30 days.⁷

International comparisons

International data are available for 15-year-old persons who reported having smoked within the last 30 days. The proportion of Australians in this category was 11%, which was comparable to the figure for New Zealand (12%) and the United States of America (11%).¹⁰

Trends

The prevalence of smoking reported among secondary school students aged 12-17 years has decreased over the last three decades, with the proportion reporting that they have never smoked increasing from 31% of persons (29% of males and 33% of females) in 1984 to 82% of persons (82% of males and 83% of females) in 2017.⁶ Similarly, daily smoking rates for secondary school students aged 12-17 years also decreased from 8% of persons (8% males and 7.5% of females) in 1984, to 1% of persons (1% of males and 1% females) in 2017.⁶

Aboriginal and Torres Strait Islander peoples

Smoking prevalence data for Aboriginal and Torres Strait Islander peoples aged 12-17 years are available for the period 2005-2017.

The proportion of Aboriginal and Torres Strait Islander peoples aged 12-17 years reporting that they had never smoked, has increased from 49% in 2005 to 70% in 2017.

The proportion of Aboriginal and Torres Strait Islander peoples aged 12-17 years reporting that they had smoked within the last 30 days decreased from 24% in 2005 to 14% in 2017.

Tobacco control in Australia

From 1984 to 2017, there was an overall decrease in the proportion of adolescent smoking in Australia, although this downward trend was not consistent. A decline was observed through the 1980’s until the 1990’s when prevalence plataeued.⁷ After 1996, prevalence began to decline again and by 2017, only 1% of adolescents aged 12 -17 years reported smoking daily.^{6, 9} The decrease in smoking prevalence after the late 1990s may have been influenced by the launch of the National Tobacco Campaign in 1997.⁹ Further decreases in prevalence may have been stimulated by introduction of other tobacco control initiatives such as graphic health warnings on cigarette packs, tobacco excise increases and the introduction of plain packaging.⁹

Tobacco smoking is a major public health issue in Australia and internationally. Adolescent smoking rates in Australia are lower than for most developed countries, and are very similar to rates for New Zealand and the United States.^{6, 10} The reduction in adolescent smoking rates in Australia point to the effectiveness of multiple public health interventions over recent decades.⁹

About the data

Numerator: Secondary students aged 12 to 17 years (in Years 7 to 12) reporting their level of tobacco usage.

Denominator: Secondary students aged 12 to 17 years (in Years 7 to 12) surveyed across Australia at schools which were randomly sampled and weighted so as to represent geographic and educational dispersion of the populations.

Definitions

Proportion of 15-year-olds reporting having smoked once in the previous week:

The proportion of 15-year-olds reporting having smoked at least one cigarette in the previous week is provided in each report from 1984 to 2017.
In 2008 -2014, proportions were rounded in source documents to the first decimal place (prior to 2008 and in 2017 they were rounded to the nearest integer).

Confidence intervals:

From 1984 onwards, 95% confidence interval estimates were provided for different proportions by age and sex.
95% confidence intervals are adjusted for the clustering of students at separate schools.

Inclusions/exclusions: Secondary school students from all states and territories are included, except the ACT in the period in 1984 to 1993, and South Australia in 1997. Prior to 2015, Year 7 students in Queensland where generally still in primary school; as a result, some primary school students are included. The ASSAD surveys only include those attending school on the day of the survey and having parental consent.

Coverage/Scope:

The ASSAD surveys had sample sizes of 21,904 (1984), 19,166 (1987), 24,892 (1990), 22,696 (1993), 29,850 (1996), 25,486 (1999), 23,417 (2002) 21,805 (2005), 24,408 (2008), 26,194 (2011), 23,007 (2014), and 19,115 (2017).

International data

“Daily smokers” are defined as the percentage of the population aged 15 years or over who reported that they were daily smokers.

International comparability is limited due to the lack of standardisation in the measurement of smoking habits in health interview surveys across OECD countries. There is variation in the wording of the questions, the response categories, and in related administrative methods.
