According to a new study of 38,480 men and women published in the Mayo Clinic Proceedings, researchers have found that measuring the impact of fitness on premature death is a good indicator of people’s risk for premature death.

Researchers from the K.G. Jebsen Center for Exercise in Medicine, at the Norwegian University of Science and Technology, looked at whether including fitness along with more well-known risk factors — such as high blood pressure, family history, or smoking and alcohol consumption — could “improve the reliability of predicting premature death.”

Based on results from the participants who were followed for up to 16 years, co-authors Javid Nauman, PhD and Bjarne M. Nes found that “estimating fitness was enough to predict future risk of premature death from all causes. There was no need to perform complicated risk score algorithms that traditionally are used to calculate risk.”
