Personal activity intelligence and mortality : Data from the Aerobics Center Longitudinal Study
2021
Importance Personal activity intelligence (PAI) is a novel activity metric that can be integrated into self-assessment heart rate devices, and translates heart rate variations during exercise into a weekly score. Previous studies relating to PAI have been conducted in the same populations from Norway where the PAI metric has been derived, limiting generalizability of the results. Objective To test whether PAI is associated with total and cause-specific mortality in a large cohort from the United States. Design Aerobics Center Longitudinal Study (ACLS) - a prospective cohort between January 1974 and December 2002 with a mean follow-up of 14.5 years. Setting Population-based. Participants 56,…
Temporal changes in personal activity intelligence and mortality : data from the aerobics center longitudinal study
2021
Background Personal activity intelligence (PAI) is a metric developed to simplify a physically active lifestyle for the participants. Regardless of following today's advice for physical activity, a PAI score ≥100 per week at baseline, an increase in PAI score, and a sustained high PAI score over time were found to delay premature cardiovascular disease (CVD) and all-cause mortality in a large population of Norwegians. However, the association between long-term temporal change in PAI and mortality in other populations have not been investigated. Objective To test whether temporal change in PAI is associated with CVD and all-cause mortality in a large population from the United States. Method…
