Background:Physical activity(PA)is important for cancer *** of remotely delivered interventions are needed to assist in reaching under-served non-metropolitan cancer *** objective of this study was to ascertain whether wearable technology,coupled with health coaching was effective in increasing PA in breast and colorectal cancer survivors living in regional and remote areas in ***:Cancer survivors from 5 states were randomized to intervention and control *** participants were given a Fitbit Charge 2TMand received up to 6 telephone health coaching *** participants received PA print *** assessments at baseline and 12 weeks measured moderate-to-vigorous PA(MVPA),light PA,and sedentary ***:Eighty-seven participants were recruited(age=63±11 years;74(85%)female).There was a significant net improvement in MVPA of 49.8 min/week,favoring the intervention group(95%confidence interval(95%CI):13.6-86.1,p=0.007).There was also a net increase in MVPA bouts of 39.5 min/week(95%CI:11.9-67.1,p=0.005),favoring the intervention *** groups improved light PA and sedentary behavior,but there were no between-group ***:This’s the first study to demonstrate that,when compared to standard practice(i.e.,PA education),a wearable technology intervention coupled with distance-based health coaching,improves MVPA in non-metropolitan cancer *** results display promise for the use of scalable interventions using smart wearable technology in conj.n.tion with phone-based health coaching to foster increased PA in geographically disadvantaged cancer survivors.
