A study published this week in BMC Medicine as part of the SAX Institute's 45 and Up Study adds weight to the theory that smoking kills. Tobacco smoking and all-cause mortality in a large Australian cohort study: findings from a mature epidemic with current low smoking prevalence looked at over 200,000 adults over 45 in New South Wales and assessed their relative risk for all-cause mortality among current, past and never smokers, adjusting for age, education, income, residence, alcohol use and body mass index.
The results indicate that in Australia, up to two-thirds of deaths in current smokers can be attributed to smoking, with current smokers estimated to die an average of 10 years earlier than non-smokers. The indications for smoking cessation supports other studies which indicate that cessation reduces mortality the earlier in life cessation occurs.
