Be on the move and live longer

Get up and be on the move and live longer, says a new University of Pennsylvania study.

The Penn researchers examined data from about 3,000 people from ages 50-79 who were participants in the National Health and Nutrition Examination Survey (NHANES) conducted by the Centers for Disease Control and Prevention (CDC).

They found that those who exercised and moved around and spent less time sitting tended to live longer.

Lead author and doctoral candidate in demography at Penn, Ezra Fishman said:

The folks who were walking around, washing the dishes, sweeping the floor tended to live longer than the people who were sitting at a desk.”

Although previous studies have shown similar results, this one is a little different. Most studies of this nature ask participants to report their own activity information, which most people end up exaggerating. However, this study didn’t leave it up to the participants. Instead the study used motion trackers, also called accelerometers.

As reported in the study abstract:

After adjusting for potential confounders, including age, sex, race/ethnicity, education, body mass index, and the presence of comorbid conditions, those in the highest tertile of total activity counts had one fifth the risk of death of those in the lowest tertile (HR: 0.21, 95% CI: 0.12, 0.38), and those in the middle tertile had one third the risk of death (HR: 0.36, 95% CI: 0.30, 0.44). In addition, replacing thirty minutes of sedentary time with light activity was associated with significant reduction in mortality risk (After 5 years of follow-up: HR = 0.80, 95% CI: 0.75, 0.85). Replacing thirty minutes of sedentary time with MVPA was also associated with reduction in mortality risk (HR = 0.49, 95% CI: 0.25, 0.97).

One of the greatest takeaways the researchers got is that even adding simple exercise like 10 minutes of light activity a day can make a difference. Replacing 30 minutes of sedentary time with physical activity showed even better results.

You didn’t have to even get a good sweat to experience the reduced likelihood of mortality,” Fishman said. “Activity doesn’t have to be especially vigorous to be beneficial. That’s the public health message.”
