Brief summary
This study, Fitness Intensive Therapy (Get FIT) to Promote Healthy Living in Older Adults, will test a mobile-health based intervention which includes use of a Fitbit activity tracker for 3 months, a smartphone application that tracks daily food intake, and one 45 minute counseling session to create personal goals and provide patient education by a health coach; versus Get FIT+ (the same items) plus personalized text messages focusing on participant's activity and nutrition progress as monitored in the app, from the health coach for 3 months. The investigators will measure the impact on participant's diet, physical activity, clinical outcomes, psychosocial well-being, and engagement.
Detailed description
This study, Fitness Intensive Therapy (Get FIT) to Promote Healthy Living in Older Adults, will test 2 behavioral interventions in community-dwelling older adults (age ≥ 60 years) at intermediate and high risk of cardiovascular disease. 1. Get FIT: use of a Fitbit activity tracker, smartphone application to track daily food intake, one 45 minute counseling session to create personal goals and provide patient education by a health coach; vs. 2. Get FIT+: use of a Fitbit activity tracker, smartphone application to track daily food intake, one 45 minute counseling session to create personal goals and provide patient education by a health coach, and personalized push-only text messages from the health coach based on participant's progress as monitored electronically in the application. Each intervention lasts 3 months, with outcomes measured at baseline, 3 months, and 6 months.
Interventions
BEHAVIORALGet FIT
The Get FIT arm includes use of a free commercially available smartphone application to track daily food intake for 3 months; use of a Fitbit activity tracker for 3 months; and one 45 minute behavioral counseling session to set personal goals and provide education by a health coach.
BEHAVIORALGet FIT+
The Get FIT+ arm includes use of a free commercially available smartphone application to track daily food intake for 3 months; use of a Fitbit activity tracker for 3 months; one 45 minute behavioral counseling session to set personal goals and provide education by a health coach; and personalized text messaging for 3 months by a health coach. The health coach will have access to these participants' daily food and activity data through the smartphone application, and will monitor progress and send push-only text messages to participants in this group based on the participant's goals and progress in the areas of physical activity, nutrition, and weight loss.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline adherence to recommended self-care behaviors at 3 months and 6 months | baseline, 3 months, 6 months | The Medical Outcomes Study Specific Adherence Scale measures patient adherence to 8 recommended health behaviors (3 items on specific diet/nutrition, 1 item on smoking cessation, 1 item on alcoholic beverages, 1 item on taking prescribed medications, 1 item on regular exercise, 1 item on weight/fluid, 1 item on symptom management). Participants circle the answer that best corresponds to their behavior in the last 4 weeks (None of the time; 1-A little of the time; 2-Some of the time; 3-A good bit of the time; 4-Most of the time; 5-All of the time). Scoring is the average of the items for a total specific adherence score. |
