Targeted Health Coaching to Improve Physical Activity Post-Structured Cardiac Rehabilitation

Study Overview
=================
Brief Summary
-----------------
To identify factors and triggers influencing physical activity (PA) participation after structured cardiac rehabilitation (CR) among older adults who have enrolled in a center-based CR program, and compare the effects of a targeted health coaching intervention versus standard care immediately following structured CR on PA maintenance and functional fitness.

Detailed Description
-----------------
Approximately 800,000 individuals in the United States have a heart attack every year, with almost 1 in 4 of those individuals already having suffered a previous heart attack. Attending cardiac rehabilitation (CR) following a cardiovascular event improves cardiorespiratory fitness and health-related quality of life, as well as decreases the risk of future illness and death from heart disease. Unfortunately, once an individual finishes a CR program, continued participation in physical activity (PA) too often reverts to previous sedentary patterns, limiting beneficial health effects. Continued participation in PA post-CR is especially challenging among older adults - likely due to a lack of self-efficacy and confidence in their ability to perform PA due to either their age or other health conditions that make PA more challenging. However, the need to address other health conditions, in conjunction with the benefits of improved strength and mobility, makes continued PA participation following a structured CR program even more useful for older adults. Although individuals typically understand habitual participation in PA is good for their health, we poorly understand why some individuals successfully adhere to and maintain PA habits, while others succumb to barriers preventing them from maintaining the health benefits beyond CR. In addition to understanding factors and triggers influencing PA maintenance beyond CR, little research has developed or investigated interventions targeting this important transition period following structured CR programming to promote continued PA participation at home. Therefore, this proposal aims to 1) identify factors and triggers influencing PA participation after a traditional 36-session CR program (Stage 0); and 2) test a targeted health coaching intervention using these identified triggers to optimize PA maintenance and mobility among older adults who completed a center-based CR program.

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Targeted Health Coaching Group<br> | Behavioral: Targeted Health Coaching Group<br>* Participants in the THC group will receive an exercise prescription (steps/day) based on their last cardiac rehabilitation session exercise prescription. Participants will be provided a Garmin wearable device to track steps/day. Additionally, participants will partake in 6 virtual or in-person health coaching sessions lasting approximately 30-60 minutes in duration. These sessions will take place approximately every other week during the 3-month intervention period.<br>|
| Placebo Comparator: Standard Care Group<br> | Behavioral: Standard Care Group<br>* Participants in the SC group will receive an exercise prescription (steps/day) based on their last cardiac rehabilitation session exercise prescription. Participants will be provided a Garmin wearable device to track steps/day. Additionally, participants will be provided with a single virtual or in-person education session, lasting approximately 30 minutes, at the beginning of the 3-month intervention period.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Physical Activity Maintenance | Steps/day will be averaged across the intervention period | Baseline, 3 months | 
| Percent Change in Physical Activity Maintenance | Calculated as (steps/day completed) divided by (steps/day prescribed) times 100 and average across the study period | Baseline, 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Senior Fitness Test Score (SFT) | Summed score from the six activities of the senior fitness test will be averaged. The six activities are: chair stand, arm curl, chair sit and reach, back scratch, 8-ft up and go, and 6-minute walk. | Baseline, 3 months |
