Study shows PAI Health app keeps employees active and engaged during COVID-19, reducing average Fitness Age by 5 years over 16 weeks

Vancouver, Canada
March 11, 2021

Participants with higher risk experienced the greatest health improvements including the least fit and older population segments

PAI Health today announced the results of a global corporate study that spanned 5 regions, included 491 participants and ran the course of the initial peak COVID-19 pandemic from March to June 2020. PAI Health partnered with Gen Re, a global reinsurer, inviting their employees to join a 16-week study where participants used the PAI Health app with wearable devices. Quantitative and qualitative analysis was conducted to assess many factors, including PAI’s efficacy at motivating people to become more active or stay active and for whom PAI works best. The full white paper can be accessed on the PAI Health website.

The study found:

• The overall cardiorespiratory fitness levels of participants improved, with the average Fitness Age decreasing by 5 years.

• Cardiorespiratory fitness (CRF) is a leading indicator of health and longevity, commonly measured as VO2 max and recommended as a clinical vital sign by the American Heart Association. PAI Health’s algorithm converts VO2 max to Fitness Age, which helps people understand how fit they are compared to their actual age.

• PAI is particularly effective in motivating the least active/fit population, as they saw increases in their average PAI Score by 41%, with 91.5% improving their Fitness Age (cardiorespiratory fitness).

• PAI helped this cohort increase and maintain physical activity habits, suggesting PAI can help motivate the hardest-to-reach groups.

• PAI was also particularly effective for older participants, with the 50+ years group having the highest PAI Scores and greatest improvements in cardiorespiratory fitness.

These findings suggest that PAI can support healthy behaviour change and mortality risk reduction for cohorts that are at the highest risk of CVD mortality, including the least fit and older populations. The PAI Score has been associated with significant mortality risk reduction for healthy individuals as well as those with chronic health conditions, such as hypertension, obesity, and type 2 diabetes. Published studies show that on average, people who maintain a PAI Score of 100 or more can experience a 25% decrease in CVD mortality risk, and even greater risk reduction amongst cohorts with chronic conditions.

“The results of this study are very exciting as it further validates PAI’s value in helping to solve one of the world’s most pressing problems, which is inactive lifestyles,” says Sally Powell, General Manager, PAI Health. “CVD is the number one cause of death worldwide, and COVID-19 has brought new challenges for the health and wellness industry. We are confident that our solution can drive meaningful health outcomes by giving people a tool that provides personalized guidance and motivation to stay active by doing any type of activity, anywhere.”

PAI Health’s proprietary metric PAI (Personal Activity Intelligence) provides actionable insight on how much activity is needed for each individual to improve or maintain good CRF and maximize their heart health protection. PAI Health leverages its expertise in biometric sensing and algorithm development to offer science-backed data insights for the health and wellness industry, including insurers, healthcare providers, wellness programs and wearable technology companies. The company’s suite of tools includes a mobile app, an administrative reporting dashboard, and an application programming interface (API) for easy integration into third party apps.

The PAI algorithms were derived from one of the world’s most extensive health studies involving 45,000 people over 25 years, with further validation across broader populations of over 730,000 people, with over a million person-years of data.
