Chicago: Quitting smoking has benefits even if it happens later in life, claims a new study after finding a strong link between smoking cessation and reduced mortality among people aged 60 or older. The study, a meta analysis of 17 studies that looked at the risk of all-cause mortality in smokers 60 or older, found smoking cessation was linked with a 28 per cent reduction in mortality risk and its benefits were evident in all age groups including those aged 80 years and older. Smoking is a known risk factor for many chronic diseases, including cardiovascular disease and cancer, however, the epidemiological evidence mostly relies on studies conducted among middle-aged adults, according to the study.
