Study: smoking-associated mortality increases in Asia

03 Apr 2019. A new study which was published in JAMA Network Open has found that smoking-related mortality among men living in Asia has continued to increase, Research Matters reported.

The study led by researchers from Vanderbilt University, USA, examined the trends in tobacco use in China, Japan, South Korea, Singapore, Taiwan and India. According to the report, the study with one million participants is a meta-analysis of 20 cohort studies in these countries that collected data on the tobacco habits from representative individuals over 35 years of age.

Study results show on average, 65.4 per cent of men and 7.8 per cent of women smoked tobacco in Asia. With the exception of urban Chinese women, the number of cigarettes smoked per day has continued to rise in all population groups, with Japanese men topping the list. The number of cigarettes smoked per day was 16.5, with 17.2 cigarettes for men and 11.2 cigarettes for women, the report said.

The study also found that smoking-associated mortality rates, including that due to lung cancer, increased in all the countries. For men born during the 1930s or later, the numbers increased to 29.3 per cent total mortality and 68.4 per cent lung cancer deaths, according to the report.
