The study showed that smokers have three times higher risk of premature death from these pathologies than non-smokers.
British scientists have calculated the likelihood of premature death from cardiovascular disease in smokers and those who quit smoking. They also confirmed that the highest likelihood of death is among those who started smoking in childhood. New research published at Journal of the American Heart Association.
According to the study, the overall risk of premature death (before the age of 75) from cardiovascular disease in smokers was three times higher than in nonsmokers. It was higher for those who started smoking before the age of 15, and the highest for those who first started smoking before age 10.
Quitting smoking at any age reduced the risk of death associated with it. The earlier people quit smoking, the greater the effect.
- The risk of premature death from heart disease or stroke in those who quit smoking at age 15-34 was about the same as that of nonsmokers.
- After quitting smoking at 35-44 years, the risk is 20% higher.
- Those who quit smoking at 45-54 years old – 60% higher.
- For those who quit smoking at 55-64 years of age – 70% higher.
Scientists used data that were collected from 1997 to 2004 during the annual survey conducted in the United States (US National Health Interview Survey). The study included information on 390 thousand people aged 25-74 years. People who smoked reported at what age they started smoking.
“The age at which a person starts smoking is an important and often overlooked factor. Those who started smoking at a young age are especially at high risk of premature death from cardiovascular disease. But smoking cessation significantly reduces this risk, especially in those who quit early. The fight to stop smoking remains a top health priority worldwide. ” considers Blake Thomson of Oxford University, co-author of the study.
Scientists emphasize that fighting smoking among young people saves lives. They add that the message about the benefits of quitting smoking should be prominent in advocacy.
