On average, Americans walk 3,000 to 4,000 steps a day. Could adding to that step count lead to a longer life?

According to a new study by the University of Minnesota School of Public Health, physical activity levels were a better predictor of mortality than obesity, diabetes, smoking or even heart disease.

School of Public Health Assistant Professor Erjia Cui, who co-authored the study, is available for comment on how daily movement is a key factor in longevity.

“Age has long been recognized as a strong predictor of mortality. Our nationwide study showed that physical activity measures perform as well as, or even slightly better than, age — making physical activity one of the strongest predictors of mortality.”

 “Of all physical activity measures, total steps during the most active 10 hours or throughout the day are the strongest predictors of mortality. The message here is clear: moving more will benefit your long-term health. Encourage yourself to increase daily activity, and if you have a wearable device like a FitBit or Apple Watch, look at the numbers — they actually matter.”

Erjia Cui is an assistant professor in the University of Minnesota School of Public Health. His research looks into advancing functional data analysis methods and creating reproducible software to support them, and assesses the impact of objectively-measured physical activity collected from wearable devices on aging, disease progression and mortality.
