Most of them premature death today they are caused by diseases like cancer, heart disease, strokes, problem respiratory system or in the liver. Often they have their own origin; however, others are caused by a underlying factors specifically: habits smoke. A recent study determined that cigarrillo, especially when adopted at a very young age, almost can tripled the chance of premature death.
Studies conducted by George Institute for Global Health at the University Oxford and published by the Journal of the National Heart Association (AHA) in the United States, starting with an extraordinary statistic: “The Smoking causes about 100,000 deaths per year in the United States due to cardiovascular disease. In 2018 there were several 25 million smokers, among them 5 million who started smoking regularly before the age of 15“.
Although it is known that people who smoke every day are more likely to die prematurely, research on the details is lacking. And that is what the group led by epidemiologists is dedicated to Blake Thompson, through analysis of the United States National Health Survey and the country’s National Death Index.
The study confirmed what he knew, and something else: people who smoke every day have “nearly tripled the risk of premature death from cardiovascular disease compared to those who have never smoked ”, a the risk was “higher among those who started smoking before age 15The study also differentiated between groups who started smoking before 10 years and found it to be the one with the “highest risk of all.”
However, research by Thompson and his colleagues does not appear to be the last sentence: “Quitting smoking at any age is associated with a much lower risk ”, highlighted text.
For example, people who are they quit smoking between the ages of 15 and 34 presented about the same risk death from coronary heart disease or stroke than people who do they never smoke. And those who quit smoking between 35 and 44 years had a 20% higher risk.
After that threshold, however, the picture is different: flat if you quit smoking between the ages of 45 and 64, it could be too late so that the organism recovers from the damage produced by habit, since then premature mortality in that group was 70% higher, because of coronary heart disease or stroke.
“That the age at which a person starts smoking is an important factor, and one that is often overlooked. And those who started smoking at an early age were at increased risk of dying prematurely, “said Thomson, the paper’s lead author, of their main findings. The statement added: “However, quitting can reduce that harm substantially, especially for those who did it earlier. Getting people to quit smoking remains a top global health priority“.
Until this study, it was impossible to judge precisely – that is, in numbers: in years of life, in percentage of risk of premature death – the importance of the age at which smoking began. Common sense may have shown that it was a bad thing, but now it is known that it started smoking in adolescence is “an underappreciated and determinant of cardiovascular mortality into adulthood, ”something that currently holds true for 5 million smokers in the United States if they don’t quit.
That, he repeated the job, as allowed by the other central lines, if done before the age of 40 years, “avoid 90% excess cardiovascular risk” and also “excessive risk of death from other smoking-related illnesses.”
Thompson’s research started from a previous study conducted on 120,000 adult smokers in Indonesia Cuba, which shows an association between smoking before age 15 and decreased life expectancy. Work on the numbers The United States analyzed data from 390,929 people aged between 25 and 74, all daily smokers: occasional smokers excluded. The data includes medical records, lifestyle and demographic information in between 1997 and 2014.
According to epidemiologists, 4,479 people in the study died before their 75th birthday from coronary heart disease or stroke: 58% had never smoked, 23% had quit, and 19% were still smoking. Among the latter group, 2% had adopted the habit before the age of 10 and 19% between 10 and 14 years.
“People who quitting smoking at age 40 reduces the increased risk of premature death from coronary heart disease by 90%, the data show, “according to the analysis. “Those who did it between the ages of 45 and 54 had an approximately 60% higher risk of premature death than non-smokers.”
Thompson and his colleagues are now preparing to studied the relationship between smoking, especially early death, and premature death from other reasons, such as respiratory disease and cancer. “Preventing new generations from smoking can save lives, but we must also emphasize that quitting smoking can save lives today and for years to come,” he concluded.
