A study carried out in the United Kingdom revealed that the life expectancy for men could be reduced by 10–15 years after the age of 50 due to smoking.

The British Medical Journal carried out a study over a time period of 38 years in the United Kingdom which examined the health of 19,000 men aged 40–69. They were examined between 1967–1970. After tracing the history of the men, the survey revealed that smoking, high blood pressure and high cholesterol reduced the life expectancy of men by 10–15 years after they reached the age of 50. The research was published on the BMJ‘s website on Friday.

The researchers from the University of Oxford in England were focussing on smoking, high blood pressure and cholesterol due to the fact that they are the main cardiovascular risk factors. Dr. Robert Clarke from the university said: “We’ve shown that men at age 50 who smoke, have high blood pressure and high cholesterol levels can expect to survive to 74 years of age, while those who have none of these risk factors can expect to live until 83. It is precisely this kind of very prolonged follow-up study that is necessary to get these results — that modest differences in heart risk factors can accurately predict significant differences in life expectancy.”

“The results give people another way of looking at heart disease risk factors that can be understood more readily. If you stop smoking or take measures to deal with high blood pressure or body weight, it will translate into increased life expectancy.”
