The habits are recognizable - eating a healthy diet, exercising regularly, drinking only in moderation, not smoking and maintaining a healthy body weight - but the study sought to quantify the exact extent to which they could impact a person's health and longevity.
"The projected life expectancy at age 50 years was on average 14.0 years (95% CI, 11.8-16.2) longer among female Americans with 5 lowrisk factors compared with those with zero low-risk factors; for men, the difference was 12.2 years (95% CI, 10.1-14.2)", the researchers reported in their study, which was published in the journal Circulation on Monday.
A woman jumps into Lopez Lake, U.S. Exercise has been linked to a higher life expectancy in a new study. About 610,000 people die of heart disease in the US each year, which is about one in every four deaths, according to the Centers for Disease Control and Prevention. What are these five healthy habits?
Compared with those who did not follow any of the healthy lifestyle habits, those who followed all five were 74 per cent less likely to die during the study period.
Now a new study claims it has calculated the five major pillars of a long lifespan, suggesting that if you adopt them early enough, they can add more than a decade to your life. Combined with data from the National Health and Nutrition Examination Survey (NHANES) data and mortality data from the Centers for Disease Control and Prevention (CDC), the researchers used this data to estimate the impact of lifestyle factors on the life expectancy of USA citizens.
The study had some limitations, including that the data on adherence to the five lifestyle factors were all self-reported, making outcome vulnerable to measurement errors.
Women who maintained the healthy lifestyle gained, on an average, 14 years of life, the study suggested.
Every year around 100,000 people in the United Kingdom die as a result of smoking, with many more living with debilitating smoking-related illnesses.
"I do think people need to step up and take some personal responsibility, but as a society we need to make it easier for people to do that", he said. "Certainly, maintaining a reasonable body-mass index is a great way to protect oneself against the development of diabetes", Vaughan said.
"This study underscores the importance of following healthy lifestyle habits for improving longevity in the USA population", said Frank Hu, chair of the Department of Nutrition at Harvard Chan School and senior author of the study. Nearly 14,000 of these deaths were due to cancer, according to the study, and nearly 10,700 were due to cardiovascular disease.
