| Purpose: |
|
The investigators propose a randomized controlled trial based on the Behavioral Ecological
Model to evaluate: (1) the effectiveness of an internet-based fitness walking program
delivered to patients with risk factors for cardiovascular disease and stroke; and (2) the
contribution of social support networks to enhancing the effectiveness of the internet-based
fitness walking program. The investigators will recruit 220 patients who are sedentary and
have risk factors for cardiovascular disease and randomly assign them to one of the
following groups: 1. Internet-based fitness walking program (WalkLink); 2. Internet-based
fitness walking program plus social support network intervention (WalkLink+); and 3. Minimal
treatment control group (usual care).
The primary specific aims of this study are to:
1. Evaluate the effects of WalkLink and WalkLink+ relative to a minimal treatment control
group on change in: aerobic fitness, walking quantity, blood pressure, body
composition, body mass index (BMI), and amount and frequency of moderate and vigorous
walking and physical activity from baseline to posttest, and at 6-month follow-up.
2. Compare the differential effectiveness of WalkLink+ to WalkLink on change in: aerobic
fitness, walking quantity, blood pressure, body composition, BMI, and amount and
frequency of moderate and vigorous walking and physical activity from baseline to
posttest, and at 6-month follow-up.
3. Evaluate the mediator and moderator effects of selected individual-level
self-management skills (goal setting, planning, self-monitoring), social support
variables (number of activity partners and networks, social cues for walking, social
praise/reinforcement), and physical-ecological variables (neighborhood walkability,
physical cues for walking) on WalkLink and WalkLink+ treatment outcomes.
