Smoking prevalence - adults | National Cancer Control Indicators

Published

22 Nov, 2017

Tobacco use is the single largest cause of cancer globally and the predominant cause of lung cancer.¹ The risk of developing lung cancer due to tobacco smoking increases with the duration of smoking and the numbers of cigarettes smoked per day.²

Summary

Smoking prevalence in Australia is decreasingFrom 2001 to 2014-15, the proportion of adults smoking daily decreased from 22.4% to 14.5%.

Smoking prevalence is higher among Indigenous personsIn 2014-15, 40.6% of Indigenous adults smoked daily, compared with 14.5% of non-Indigenous adults (age-standardised data).

Smoking prevalence is higher for persons living in regional and remote Australia, and in lower socioeconomic status areasIn 2014-15, more than 20% of adults living in Outer Regional and Remote areas smoked daily, compared to only 13% of adults living in Major Cities. In the same period, more than 20% of adults in the lowest socioeconomic status areas (SES1) were daily smokers compared to less than 10% of adults living in the highest socioeconomic status areas (SES 5).

Australia has one of the lowest smoking prevalence rates in the worldCompared with selected developed countries, Australia had the lowest proportion of persons aged 15+ years who were daily smokers (12.4%).

About this measure

About 90% (Australian men) and 65% (Australian women) of lung cancers are attributable to tobacco smoking.³It is projected that in Australia in 2017, 7,094 males and 5,340 females will be diagnosed with lung cancer, and that it will be the most common cause of cancer death.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.¹An 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 recent meta-analysis of nearly 32,000 breast cancer cases.⁵

The data in this measure show proportions of adult Australians aged 18 years or over indicating that they did not smoke, and those reporting smoking on a daily basis.

Current status

In 2014-15, 84.0% of persons (81.1% of males and 86.7% of females) aged 18 years and over reported that they did not smoke, whilst 14.5% (16.9% of males and 12.1% of females) reported smoking on a daily basis.⁶Smoking prevalence was similar across the age groups from 18 to 64 years of age, and lower among those aged 65 years and over.

Aboriginal and Torres Strait Islander peoples

Smoking prevalence is higher among Australia’s Indigenous population. In 2014-15, the age-standardised proportion of daily smokers was 40.6% for Indigenous Australians and 14.5% for the non-Indigenous population.⁷

Remoteness and socioeconomic status (SES)

In 2014-15, the proportions of daily smokers were highest among Australians living in Outer Regional and Remote areas, and among Australians living in areas of higher socioeconomic disadvantage (lower socioeconomic status, SES).

International comparisons

International data are available for daily smokers aged 15 years or more. The proportion of Australians who were daily smokers was 12.4%, which was comparable to the USA (11.8%) and Canada (12.5%) figures.⁸

Trends

The prevalence of smoking among adult Australians has decreased over the past two-and-a-half decades. From 1989-90 to 2014-15, the proportion of persons reporting that they did not smoke increased from 71.6% to 84.0% (from 67.9% to 81.1% among males, and from 75.3% to 86.7% among females).^6,9-14 Daily smoking rates were first reported in 2001; the proportion of persons reporting that they smoked daily decreased from 22.4% in 2001 to 14.5% in 2014-15 (from 25.4% to 16.9% among males, and from 19.5% to 12.1% among females).^6,11-14

Age groups

For those years where data were available for all age groups (2001 to 2014-15), larger increases in persons reporting that they did not smoke were observed in the 18-24, 25-34 and 35-44 years age groups than in 45-54, 55-64, 65-74 and 75+ years age groups. Similarly, larger decreases in proportions of persons smoking daily were observed for males and females aged under 45 years.^6,11-14

Aboriginal and Torres Strait Islander peoples

The age-standardised proportion of Indigenous persons who were daily smokers decreased from 51.0% in 2001 to 40.6% in 2014-15. For the non-Indigenous population, the age-standardised proportions who were daily smokers were 22.4% in 2001 and 14.5% in 2014-15.^7,15

Remoteness and Socioeconomic status (SES)

From 2001 to 2014-15, decreases in daily smoking were seen across all remoteness area groupings; the largest decreases were among Australians living in Major Cities. For daily smoking rates by socioeconomic status, data were available from 2004-05 for the lowest and highest quintiles. From 2004-05 to 2014-15, there was a greater reduction in daily smoking rates among Australians living in areas of greatest socioeconomic disadvantage than among those living in the least disadvantaged areas.^6,11-14

Tobacco control in Australia

The reduction in prevalence of adult smoking in Australia from 1989-90 to 2014-15 appears to have occurred mostly in age groups under 45 years old. Cigarette smoking often becomes established in adolescence. Young people who begin smoking at an earlier age are more likely to develop long-term nicotine addiction.¹⁶ The reduction in smoking prevalence in age groups less than 45 years old may reflect reductions in teenage smoking prevalence over the last 15-20 years (see NCCI measure Smoking prevalence - Adolescents). The establishment of the first National Tobacco Campaign in 1997 likely contributed to the decline in smoking prevalence,^17,18 and this was complemented by promotion of other tobacco control initiatives at the Commonwealth and state and territory level. This includes: graphic health warnings on cigarette packs, tobacco excise increases and the introduction of plain packaging.¹⁸

Tobacco smoking remains a major public health problem in Australia and internationally. The decrease in smoking prevalence from 1989-90 to 2014-15, and the observation that daily smoking rates in Australia are broadly similar to the lowest rates for other countries, points to positive effects of Australian public health initiatives in this field.

About the data

Smoking prevalence has been measured in terms of the proportion of the population aged 18 years and older reporting not smoking, and the proportion of the population aged 18 years and older reporting daily smoking. The proportion of persons not smoking is the sum of persons who are ex-smokers, and persons who have never smoked.

For International data daily smoking is defined as the percentage of the population aged 15 years old or over who report that they are daily smokers.

Data for adults aged 18+ is sourced from the National Health Survey, a series of Australia-wide health surveys conducted by the Australian Bureau of Statistics (ABS). Indigenous data was sourced from the National Aboriginal and Torres Strait Islander Health Surveys, and Social Surveys, also conducted by the ABS.

SES quintiles are developed from the 2011 Index of Relative Socio-Economic Disadvantage. Attributes summarised by this index include low income, low educational attainment, high unemployment and jobs in relatively unskilled occupations. SES 1 is the most disadvantaged group.

Definitions

Daily smoker was defined as smoking one or more cigarettes, cigars or pipes per day.

Ex-smoker is defined as not currently smoking, but had regularly smoked daily, or had smoked at least 100 cigarettes in their lifetime, or smoked pipes, cigars etc. at least 20 times. Note: from 1989-90 to 2001, an Ex-smoker was defined as not currently smoking but had been a regular (i.e. daily) smoker in the past.

Never smoked is defined as having never regularly smoked, and smoked less than 100 cigarettes in their lifetime and had smoked pipes, cigars, etc. less than 20 times. Note: from 1989-90 to 2001, Never smoking was defined as having never smoked regularly (i.e. daily).

Methodology

Remoteness

The Australian Statistical Geography Standard (ASGS), was used to allocate participants to a remoteness area based on their area of usual residence.

Earlier data used the now superceeded Australian Standard Geographical Classification (ASGC), 2001 and 2004-2005 data used the 2001 ASGC, 2011-2012 used 2006 ASGC and 2014-2015 data used the 2011 ASGC .

Socioeconomic status

The Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) was used to allocate participants to a SEIFA quintile based on their usual residence.

For 2004-2005 data the 2004-2005 IRSD was used and for 2011-2012 and 2014-2015 data the 2011 IRSD was used.

Data caveats

Definitions of Ex-smokers and Never smoked changed after 2001. The effect of these changes increased the number of ‘ex-smokers’ and decrease the number in the ‘never smoked’ category, but did not affect the overall number classed as ‘no smoking’.

International data

Daily smokers is defined as the percentage of the population aged 15 years old or over who report that they are 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 question, the response categories and the related administrative methods. Rates are not age-standardised.
The most recent year for international data varies between 2013 and 2017. Countries and years of most recent data are as follows:
