"We can do so much better for a long, healthy life, with fairly simple minimal changes in our behavior, and only 8% of adults in our country stick to them," he said. "The key message is that by simply changing our behavior patterns, we can make tremendous progress in terms of health and longevity, and as a country we should, I believe, facilitate it by promoting cessation of smoking by providing better physical activity environments and so on. "
The "Surprising" Influence of Behavior on Longevity
After analyzing the data, the researchers found that in 2014, life expectancy at the age of 50 should be 33.3 years for women and 29.8 years for men.
However, among adults who reported having adopted all five healthy lifestyle factors, they lived 43.1 more years among women and 37.6 more years among men.
Among the adults who reported that they did not hold on to any of the five healthy lifestyle factors, the researchers found that they only lived 29 additional years in women and 25.5 additional years in men.  "For me, the surprising result was how strong it was: what impact these simple behaviors could have on life expectancy," Stampfer said. "I was surprised that it was so pronounced."
Women averaged about 30.8% of life expectancy At the age of fifty, they achieved a reduced risk of death from cardiovascular disease by adopting five of these habits compared to zero. 21.2% were attributed to reduced cancer risk and 48% to other causes of death.
Among men, 34.1% of these percentages were attributed to a reduced risk of cardiovascular disease, 22.8% to a reduced risk of cancer and 43.1% to other causes.
The study had some limitations, including that the data on compliance with the five lifestyle factors were all self-reported, making the result prone to measurement errors.
Data analysis did not include measurements of certain health conditions that are risk factors for shorter life expectancy, such as diabetes or hypertension.
However, this limitation is both a strength and a limitation, in a sense … because what we value here is the extension of life expectancy based solely on behavior, "said Stampfer.
" Obviously it is much better to do these healthy behaviors from childhood, really, but if you are beyond the age of 50, beyond the age of 60, beyond the age of 70, it is not too late.
The factor that is stronger than & # 39;
Although the study highlighted how the combination of all five lifestyle factors might help to extend life ex-Purganz, Vaughan pointed out that every single factor was also associated with a reduced risk of premature death.
"It seems that cigarette smoking has a greater impact than other lifestyle changes or behaviors." Certainly, maintaining an adequate body mass index is a great way to protect against the development of diabetes, "said Vaughan.
"Overall, we can see the impact on longevity, but you can imagine that this is mainly due to the impact on cardiovascular risk caused by metabolic risk," Vaughan said. "It potentially indicates a definite point in life Saying age 50, if you stick to a sound paradigm, you can have an impact on your longevity and on your health span. "
"Smoking not only contributes to cancer risk but also to lung disease, heart disease and diabetes The study shows that even minimal smoking – from one to 14 cigarettes a day – is associated with increased death from cancer and heart disease, "said Der-Sarkissian, who was not involved in the new study.
Some of the other lifestyle factors, "Weight below a BMI of 30 seems to be helping significantly, according to the study." Higher body weight is associated with increased diabetes and cancer risk, among other obesity-related conditions, "he said. The study suggests a physical activity of at least 30 minutes per day of moderate or vigorous activity, including brisk walking. "19659033]
