Summary

The investigators propose a randomized controlled trial based on the Social Networks for Activity (SNAP) 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 308 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 additional social network intervention (WalkLink+); and 3. Minimal treatment control. 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: physical activity, aerobic fitness, blood pressure, body composition, and body mass index (BMI), from baseline to posttest, and at 6-month follow-up. 2. Compare the differential effectiveness of WalkLink+ to WalkLink on change in: physical activity, aerobic fitness, blood pressure, body composition and BMI 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, social cues for walking, social praise/reinforcement), and physical-ecological variables (neighborhood walkability, physical cues for walking) on WalkLink and WalkLink+ treatment outcomes.
