Personal Activity Intelligence and mortality – Data from the Aerobics Center Longitudinal Study

The purpose of this study was to test whether Personal Activity Intelligence (PAI), a personalized metric that measures and tracks physical activity, is associated with all-cause and cause-specific disease mortality in a large population from the United States.

56,175 participants were tracked, with a median 14.9 years follow-up time, during which there were 3,434 total deaths, 1,258 of which were cardiovascular (CVD) deaths.

Compared to those who were inactive, participants with a baseline weekly 100+ PAI had the following results:

  • Lived on average 4.2 years longer
  • 21% risk reduction from all-cause mortality
  • 30% risk reduction from CVD mortality
  • Smokers had 47% lower risk of CVD mortality
  • Overweight/obese participants had 36% lower risk of CVD mortality
  • Participants with hypertension had 33% lower risk of CVD mortality
The study concluded that maintaining a weekly PAI score of 100 or more was associated with alower risk of all-cause or CVD mortality consistent with the HUNT Study based on a Norwegian population, suggesting that PAI is relevant across diverse populations.
