This study investigated the feasibility, acceptability, and efficacy of the Personal Activity Intelligence (PAI) e-Health Program in people with type 2 diabetes (T2D). The results showed that the program was feasible, acceptable, and efficacious, leading to improvements in exercise capacity, sleep time, body composition, and health-related quality of life in T2D patients.
Introduction Innovative strategies are needed to enable people with type 2 diabetes (T2D) to self-manage physical activity (PA). Personal Activity Intelligence (PAI) is a new metric that uses the heart rate response to PA to inform the user as to whether they are doing enough PA to reduce the risk of premature mortality. The PAI score reflects PA over the previous 7 d with the goal to maintain a score >= 100. The aim of this study was to investigate the feasibility, acceptability, and efficacy of the PAI e-Health Program in people with T2D. Methods Thirty participants with T2D who were not meeting PA guidelines were randomly assigned to 12 wk of either 1) PAI e-Health Program or 2) PA attention control. The PAI e-Health Program consisted of receiving a wrist-worn heart rate monitor and an app with the PAI metric, and attending 4 x 2 h center dot wk(-1) sessions of exercise and counseling. Feasibility and acceptability of the program were evaluated by achievement of a PAI score >= 100 and participant feedback. Efficacy was determined from changes in glycemic control, cardiorespiratory fitness, exercise capacity (time-on-test), body composition, sleep time, and health-related quality of life. Results Program participants in the PAI e-Health Program had a mean +/- SD PAI score of 119.7 +/- 60.6 and achieved >= 100 PAI on 56.4% of the days. The majority of participants (80%) intended to continue to use PAI monitoring. Compared with control, the PAI group significantly improved their exercise capacity (mean difference, 95% confidence interval) (63 s, 17.9-108.0 s), sleep time (67.2 min, 7.2-127.1 min), total percent body fat (-1.3%, -2.6% to -0.1%), and gynoid fat percent (-1.5%, -2.6 to -0.5). Conclusions The PAI e-Health Program is feasible, acceptable, and efficacious in people with T2D.
