1.5.1 Latest estimates of prevalence among middle-aged and older adults
The 2019 National Drug Strategy Household Survey examined smoking prevalence among adults aged 40 years and over.1 As noted in the preceding section, people aged under 40 years are generally more likely to smoke than those in older age groups. Table 1.5.1 shows the prevalence of smoking at various frequencies among middle-aged and older adults in 2019.
1.5.2 Trends in smoking prevalence among middle-aged and older adults
Consistent with smoking patterns from 2001 onward, in 2016, middle-aged (40–59 years) and older (60+ years) men were significantly more likely to have smoked at some time in their lives (that is, to be a current or ex-smoker) than men aged under 40 years—see Tables 1.5.1 and 1.5.2. Patterns among women, however, have varied over time. In earlier survey years, middle-aged women were generally more likely to have ever smoked than younger women (aged under 40 years), while older women were less likely than women under 40 years to have ever smoked. In 2016, both middle-aged and older women were significantly more likely to have ever smoked than women under the age of 40.
Decreasing smoking rates among the older population reflect increased quitting activity, with past studies showing that older age groups of both sexes have the highest quit proportions (defined as the proportion of ever smokers who have quit smoking).2,3 These patterns were also seen in 2016; men and women over 60 had the highest quit proportions (80% and 78%, respectively), followed by middle-aged men and women (59% and 64%, respectively). Proportions were lowest among men and women under 40 (38% and 50%, respectively). However, tobacco-caused death and illness occurring among smokers in older age groups are also significant factors in the declining smoking rates seen in the older population, with the greatest proportion of burden of disease due to smoking affecting those aged 55–75 years.4
Table 1.5.2 and Figure 1.5.1 show that smoking prevalence has declined significantly among middle-aged and older adults since 2001 (controlling for gender). However, there was no significant change between 2013 and 2016 among either age group. Data for 2019 weekly and less-than-weekly smoking will be added once the data file for the survey becomes available.
Data from the 2019 National Drug Strategy Household Survey provides more detailed information on smoking prevalence in older Australians. In 2019, 7.9% of people aged between 55 and 64, 3.3% of people aged between 65 and 74, and 5% of people aged 75 or more smoked on a daily basis.1
