Latest analysis of the prevalence and implications of tobacco smoking in 195 countries gives some disturbing findings for low and middle income countries (LMICs) in the Asia and Pacific region. This post summarises and cites the most important findings about tobacco consumption that were recently published in The Lancet as they affect LMICs in this region, as well as updates for Australia and New Zealand which have made particularly good progress in reducing smoking prevalence. The Lancet article contains the confidence intervals of all the estimates (not always shown in this blog). Funding for the research came from the Bill & Melinda Gates Foundation and Bloomberg Philanthropies.

 Key findings at a global level

Smoking tobacco[1] remains a major public health challenge globally, especially for LMICs. The researchers find there were an estimated 933 million tobacco smokers in 2015 (latest year available). One in every four men in the world was a daily smoker. Smoking has claimed more than 5 million lives every year since 1990, rising to an estimated 6.4 million deaths in 2015: a total of over 400 million people since 1990. Smoking tobacco is the leading risk factor for cancers and chronic respiratory diseases, and the second leading risk factor for early death and disability worldwide.

Smoking contributes to years living with a disability – for example stroke and cancer – as well as premature death. The researchers therefore estimate the Disability Adjusted Life Years (DALYs), a composite measure that seeks to measure the sum of healthy lives lost to premature death combined with years of living with a disability. They estimate that smoking was ranked among the five leading risk factors by DALYs in 109 countries and territories in 2015 – a significant increase from the 88 countries and territories in 1990. This is important as years living with a smoking-attributable health burden such as stroke, cancer, or other expensive-to-treat and chronic diseases adds significant additional financial costs to public health budgets in LMICs, household budgets, and lost employment opportunities.

The latest analysis also provides for the first time estimates of the disease burden that can be attributed to tobacco smoking for a wide range of diseases including cardiovascular diseases, tuberculosis, diabetes, lower respiratory infections, asthma, cataracts, macular degeneration, fractures, rheumatoid arthritis, and peptic ulcer disease.

Importantly, the researchers find that “while there has been progress in reducing tobacco consumption globally, population growth and ageing in low and middle income countries can offset the gains.” They estimate the age-adjusted prevalence of daily smoking among men decreased globally from just over one third (34.9%) in 1990 to one quarter (25%) in 2015. For women the reduction was from 8.2% to 5.4% over the same period. These reductions were especially pronounced in high income countries and Latin America, particularly Brazil. However – and importantly – these reductions in smoking rates were more than offset by population growth, population ageing, or a combination of both. As a result there was an increase in overall smoking-attributable premature death and disability in LMICs[2] between 2005 and 2015.  

Geography and gender

There are significant differences in the prevalence of tobacco smoking based on geography, but also gender. The researchers found that over half (51.4%) of male smokers globally in 2015 were in three countries of Asia: China, India, and Indonesia. This led to an estimated 2.23 million smoking attributable male deaths in these three countries in 2015. What is also striking is the social and economic burden in these countries when the effects of smoking on premature death and smoking-related ill health (for example cancer or stroke). Table 1 shows that smoking is estimated to lead to over 54 million years lost to what could be considered healthy living among men in these 3 countries in 2015, and over 8 million years among women.

Graph 1 below shows that 18 countries in Asia and the Pacific exceed the global average prevalence for male smoking. Of particular significance in this region is the estimate that the Pacific nation of Kiribati has the highest prevalence of male smoking (47.8%, with a confidence interval 43.8-51.5) out of the 195 countries in the study. Indonesia ranks second with a male smoking prevalence rate of 46.7% (CI: 43.5-49.5).

The prevalence rates of female smoking in Asian and Pacific countries are also often higher than the global average (Graph 2). The researchers found that in 70 countries, mainly in western and central Europe, female smoking rates significantly exceeded the global average. Thirteen countries in Asia and the Pacific also have age-adjusted prevalence rates for smoking among women higher than the global average. Kiribati has the 7th highest rate of female smoking in the world, and the highest rate in the Asia Pacific region, with an estimated female age-adjusted prevalence of 24.7% (21.3-28.4 confidence interval). Kiribati is followed in the region by PNG with estimated female smoking prevalence at 15% (12.6-17.7). Smoking among women in Indonesia is this time at 3.8% and so below the global average for women.

Future trends?

The researchers find that 13 countries (including Australia, China, and New Zealand in the Asia Pacific region) had achieved significant rates of decline in smoking prevalence between 1990 and 2015.  However, they also find that Indonesia, Bangladesh, and the Philippines had not been able to achieve significant reductions in male prevalence of daily smoking since 1990. In China, India and Bangladesh female prevalence of smoking stayed low at less than 3%. Globally, female prevalence of daily smoking significantly increased in Indonesia (and Russia) since 1990, and in Timor Leste between 2005 and 2015. There was little progress in reducing female prevalence of smoking in the Philippines. (It could be argued that recent significant tax increases on tobacco – and alcohol – in the Philippines is likely to reduce male and female rates of smoking in that country).

The policy implications

There is a positive, important, and encouraging message in this latest analysis: the overall prevalence of tobacco smoking globally is reducing. More specifically, age-adjusted prevalence of daily smoking among men decreased from just over one-third (34.9%) in 1990 to one-quarter (25%) in 2015. For women the reduction was from 8.2% to 5.4% over the same period.

But there are warning signs too. The researchers find that population growth and ageing ultimately offset these reductions in prevalence and contributed to overall increases in smoking-attributable disease burden in low and middle income countries.

There are clearly particular challenges for Asia and the Pacific, home to the highest prevalence of smoking among males globally (Kiribati) and the largest numbers of smoking related deaths and disability in the world (China, India, and Indonesia). Unless countries in this region step up their efforts to control tobacco use, they will inevitably encounter higher – and largely preventable – financial costs to public health systems, and households, as well as broader economic costs through lost employment.

And a footnote

In the same week that The Lancet article came out, the financial press reported on the profitability of tobacco companies, including those in the USA. The reports noted that the Standard and Poor 500 Tobacco Index fell 22 per cent between 1998 and 2002 when there was significant litigation against tobacco companies in the US. However, over the past decade the index is up 178 per cent, while the broader S&P 500 rose by 58 per cent.

  • Thanks for highlighting this important disease burden, Ian. Tobacco is one of the leading contributors to the burden of disease among Australia’s Aboriginal and Torres Strait Islander peoples.
    In 2014-15, approximately 39% of Aboriginal and Torres Strait Islander people aged 15 years and over reported being a current daily smoker – well above the global average (29%). In remote communities it is closer to 70%. The Indigenous Health Minister Ken Wyatt AM said last week that ‘Smoking is the most preventable cause of disease and early death among Aboriginal people and accounts for almost one-quarter of the difference in average health outcomes between indigenous and non-indigenous Australians. Reducing smoking rates is central to efforts to Closing the Gap in life expectancy’
    On the Department of Health funded ‘National Best Practice Unit for Tacking Indigenous Smoking’ programme, we are using evidence to enable service providers to improve the health of Aboriginal and Torres Strait Islander people. Last week, the TIS programme released its Preliminary Evaluation report, which found that it is operating effectively; using proven approaches to change smoking behaviours, and is delivering evidence-based local tobacco health promotion activities.
    There is still a huge gap to close in Australia.
