Increasing physical activity in Cancer Survivors through a Text-messaging Exercise motivation Program (ICanSTEP).

ABSTRACT

PURPOSE: Cancer survivors are often sedentary. Self-monitoring may promote physical activity through self-activation. We conducted a pilot trial to evaluate whether wearable activity tracker with personalized text message feedback would increase physical activity. METHODS: We enrolled 30 patients with solid tumor cancers into a non-randomized prospective intervention trial (NCT02627079) 15 had completed treatment in the past year and 15 under active treatment. Each participant received an activity tracker and daily text messages personalized to their activity level. We assessed patient-reported outcomes and 6-min walk (6 MW) at baseline and 3 months. RESULTS: Twenty-six participants completed the study. There was substantial variation in baseline activity. Overall, 39% of participants increased their steps taken by at least 20%, and 23% increased their 6 MW distance by 20% or more. More participants who had completed treatment strongly agreed (73%) that the intervention increased their exercise levels than those receiving active treatment (47%). At 3 months, there was a significant improvement in median Beck Depression Inventory-II and Godin Leisure Index composite scores. At 6 months, 72% still wore their activity tracker at least 4 days per week. CONCLUSION: We found that the intervention was well-accepted with a high completion rate at 3 months and continued self-use at 6 months. In this pilot study of combined activity tracker and motivational messaging, we found a signal for increased physical activity over a 3-month period. Future research is needed to study this technique for its impact on activity and other physical and psychological measures of well-being. IMPLICATION FOR CANCER SURVIVORS Activity tracker with personalized motivational messaging may be useful in promoting physical activity in cancer survivors.
