Mortality associated with tobacco smoking continued to increase among Asian men in recent birth cohorts, according to a new analysis published in JAMA Network Open.
The pooled analysis included 1,002,258 Asian adults aged 35 years and older from 20 prospective cohort studies in the Asia Cohort Consortium, including cohorts from studies conducted in mainland China, Japan, South Korea, Singapore, Taiwan and India.
Among the study participants, there were 144,366 deaths (with 9,158 from lung cancer) during an average follow-up of almost 12 years.
The study found tobacco smoking was associated with 12.5 per cent of total deaths and 56.6 per cent of lung cancer deaths in men born before 1920; 21.1 per cent of total deaths and 66.6 per cent of lung cancer deaths in those born in the 1920s and 29.3 per cent of total deaths and 68.4 per cent of lung cancer deaths among men born in 1930 or later.
The authors said the data suggest that most Asian countries are still in the early stages of tobacco smoking epidemic and that tobacco smoking will remain a major public health threat in the coming decades.
