Smoking cigarettes could help prevent people from dying from heart attacks, a new study finds.
A study published this week in the journal BMJ found smokers who stopped smoking were more than three times more likely to live longer.
The study is the first to link a link between smoking and longer life.
More than 1,000 participants were followed up for 11 years.
They were all followed up in 2013 and 2014.
The authors, led by Philip M. Schmitt, professor of epidemiology and public health at the Johns Hopkins Bloomberg School of Public Health, examined the association between cigarette smoking and cardiovascular disease (CVD) in an older group of smokers.
They found that people who smoked had lower rates of heart disease and cancer in their 30s and 40s, and they were less likely than other smokers to have a stroke or death.
“People who quit smoking in the first place are at greater risk of heart attack or stroke,” said lead author Dr. Mark M. Liggett, director of the tobacco prevention research unit at the University of California, Los Angeles.
“These results suggest that it’s not the cigarette but the nicotine that is the cause of increased risk of these conditions.”
Smoking may be one way to cut down on the risk of death from CVD, said Dr. Andrew A. H. Rothman, a professor of medicine at Harvard Medical School and director of its Prevention Research Center.
“If people want to stop smoking, they should quit smoking tobacco, which increases their risk of dying from cardiovascular disease,” Rothman said.
Smoking may reduce the risk for certain types of cancer, he said, but the mechanism remains unclear.
“It’s not clear why smoking reduces the risk,” Rothmans said.
“This is the kind of work that we need to continue doing.”
In the study, researchers looked at data from the National Health and Nutrition Examination Survey (NHANES), which tracks people in the United States.
They also looked at mortality rates in the general population.
The researchers looked specifically at people who had died of a cause other than cancer.
The average mortality rate in this group was 14.1 per 100,000 people.
People in the second group, who were also excluded from the study because they were already dying, had a mortality rate of 3.4 per 100 000.
“The mortality risk was reduced by 40% among smokers,” said Dr, Paul Siegel, a physician and epidemiologist at the Kaiser Permanente Center for Health Research and Policy.
Siegel is the lead author on the study.
The findings were consistent across age groups, including those in their 40s and 50s.
In contrast, the mortality rate among the second and third groups was not reduced, despite smoking being associated with a higher mortality rate.
“Smoking is associated with some mortality risks that are quite small,” said Rothmans.
“But they are still very high compared to the mortality risk for other causes of death, which are lower.”
What about the health of your brain?
“There’s a lot of good evidence that smoking is associated to increased risk for dementia,” said M. Andrew S. Rothmans, professor and chair of the Department of Medicine at Johns Hopkins University School of Medicine.
There is a strong association between smoking status and dementia.” “
And it’s been suggested that smoking can increase the risk.
There is a strong association between smoking status and dementia.”
There’s also evidence that cigarette smoking increases the risk in people with schizophrenia.
“One of the things that’s particularly interesting about this study is that the risk associated with smoking in this study was quite small, with the average of only 1.2 deaths per 100 million people, and the risk was only about 4 times that of other forms of cancer,” Roths said.
However, Roths stressed that it was important to note that these results do not mean that smoking does not have an effect on the health.
“Some of the risk reduction is due to the fact that people with higher smoking rates were more likely than those who smoked less to have heart disease or stroke.
However,” he said.
He also noted that the authors had a lot more data on smoking history, lifestyle, diet, and health-related behaviors than they did smoking, which could have led to an underestimate of the effects of smoking.
“As we’ve seen, smoking is a risk factor for some diseases, but it’s also a risk in other ways,” he added.
“There is a lot that we don’t know about smoking, but there is plenty of evidence to show that smoking reduces heart disease risk, and that smoking lowers risk for all other causes.
The results are important, and there is much more work to be done to better understand this link.”
