Summary
Web-enhanced pedometers significantly increased weight loss in Veterans compared to time-based or simple pedometer goals. This internet-based walking program improved health outcomes for cardiovascular disease (CVD) risk reduction.
Area of Science:
- Cardiovascular Health
- Obesity Management
- Digital Health Interventions
Background:
- Walking programs are effective for improving health outcomes in adults at risk for cardiovascular disease (CVD).
- Self-monitoring strategies enhance adherence to walking programs.
- Internet-based interventions offer scalable solutions for health management.
Purpose of the Study:
- To compare the effectiveness of a six-month internet-based walking program using web-enhanced pedometers against time-based or simple pedometer goals.
- To determine the impact of different self-monitoring strategies on weight loss in adults at risk for CVD.
- To evaluate the efficacy of technology-assisted interventions in managing cardiovascular risk factors.
Main Methods:
- A multi-site randomized controlled trial involving 255 male Veterans with overweight/obesity (BMI ≥ 28) and at least one CVD risk factor.
- Participants were randomized into three groups: time-based walking goals, simple pedometer goals, or web-enhanced pedometer feedback with internet-mediated support.
- All participants received dietary counseling, with weight change, physical activity, and quality of life as primary and secondary outcomes.
Main Results:
- Participants using web-enhanced pedometers achieved significantly greater weight loss (-1.9 kg) compared to time-based (-0.7 kg) and simple pedometer groups (-0.6 kg) at six months.
- The study included Veterans with a mean age of 56.3 years, BMI of 36.3, and an average of 5.2 comorbidities.
- Dropout rates were similar across groups, with 72% of participants completing the six-month program.
Conclusions:
- Internet-enhanced pedometers are more effective for weight loss in Veterans than traditional time-based or simple pedometer walking programs.
- Web-enhanced feedback and internet-mediated support can significantly improve adherence and outcomes in walking interventions.
- This study highlights the potential of digital health tools in managing weight and cardiovascular disease risk factors.
