Update on numbers of tobacco-attributable deaths by country in the South-East Asia region: implications for policy.

Background: The WHO South-East Asia Region is home to around 33% of adult tobacco users. To inform tobacco control policy and practice, we conducted a study using the latest available data to update mortality attributable to overall tobacco use, including smoked tobacco, smokeless tobacco (SLT) and secondhand smoke (SHS) exposure, in the 11 countries of the Region.

Methods: We estimated smoking, SLT use and SHS exposure using the latest available surveys for each country during 2016-2021, and then estimated all-cause and lung cancer-attributable annual deaths for each using the population-attributable fraction method. Finally, we estimated the annual total tobacco-attributable deaths including all three exposures using the multiplicative aggregation method.

Results: We estimated the occurrence of 4 087 920 all-cause deaths and 105 279 lung cancer deaths annually attributable to tobacco use among the 11 countries investigated. India accounted for 63.9% of all-cause tobacco-attributable deaths.

Conclusions: The high annual number of tobacco-attributable deaths in the Region highlights the need for accelerating progress in reducing tobacco use. Implementation of the WHO Framework Convention on Tobacco Control (FCTC) and MPOWER policy package needs prioritisation at the country level. Tobacco cessation services, supply-side measures and policies to counter tobacco industry interference should be strengthened. Further work is needed to monitor progress towards FCTC implementation and analyse the impacts of policies on tobacco-related outcomes, including attributable mortality and disease burden, to inform advocacy efforts.
