Brief summary

This project is Project three of a four project Prevention Coaching Lab CREATE grant entitled Transforming Prevention into Action aimed at effectively engaging patients and their families to improve their health and medical care. This project will test the feasibility and effectiveness of the prevention focused, internet mediated healthy lifestyle Stay Strong program tailored to the needs, preferences and demographics of OEF/OIF/OND Veterans.

Detailed description

Veterans from Afghanistan and Iraq (OEF/OIF/OND) are at high risk for becoming overweight and obese. However, existing VA programs are not designed for younger Veterans who are comfortable with technology-mediated interventions, may not yet have developed obesity-related illnesses, and contain a relatively high percentage of women compared to previous Veteran cohorts. Technology-mediated lifestyle interventions that include continuous, objective home monitoring of physical activity, automated internet mediated feedback, and e-coaching increase physical activity and improve weight loss in non-Veteran populations. When delivered on a large scale, such interventions represent low cost but effective alternatives to face-to-face lifestyle change interventions that can be implemented widely in the VA health care system. Thus, this project will test the feasibility and effectiveness of the prevention focused, internet-mediated healthy lifestyle physical activity program, Stay Strong w/coaching, tailored to the needs, preferences and demographics of OEF/OIF/OND Veterans. Specifically, Stay Strong w/coaching relies on use of a wearable device, the Fitbit Charge 2, and incorporates coaching support, tailored messages, and personalized physical activity goals. Stay Strong w/coaching will be compared to the use of the Fitbit Charge 2 with standard online support (Stay Strong).

Interventions

BEHAVIORALStay Strong w/coaching

Pts randomly placed in the Stay Strong w/coaching group receive an app-mediated physical activity intervention. Pts are asked to wear a physical activity monitoring device and weigh regularly using a Bluetooth scale while participating in the study. Pts will be asked to upload the device data at least weekly and will receive tailored push notifications. Each week the pt will receive a new automatically calculated personalized physical activity goal. Stay Strong coaches will call pts up to 3 times in the first 6-8 weeks of the study to help pts meet physical activity goals including problem solving support. Pts will also be reminded to follow-up with their healthcare provider as needed for the remainder of the 12-month program.

BEHAVIORALStay Strong

Pts randomly placed in the Stay Strong arm are asked to wear a physical activity monitoring device and weigh regularly using a Bluetooth scale while participating in the study. Pts will be asked to upload the device data at least weekly. Pts will have access to a standard app-mediated intervention that is linked to the wearable device.

Participant flow

Recruitment details

Letters were mailed to potential participants. They used the information in the recruitment letter to accessed an online portal and respond to screening question. If eligible, they completed the consent documentation, baseline questionnaire, downloaded and registered the Stay Strong App. Recruitment period was from 10/1/2017 - 4/30/2018.

Pre-assignment details

After consent and prior to randomization participants were to completed baseline survey, register app, and complete a baseline physical activity (PA) period for randomization. 56 participants were excluded due to failure to complete baseline survey or register app. 52 participants were excluded due to failure to provide baseline PA.
