A web-based intervention to support increased physical activity among at-risk adults

Area of Science:

• Health Informatics
• Behavioral Medicine
• Public Health

Background:

• Physical inactivity is a major risk factor for chronic diseases like diabetes, cardiovascular disease, and depression.
• Most Americans do not meet recommended physical activity guidelines.
• There is a need for effective tools to support lifestyle physical activity interventions.

Purpose of the Study:

• To design and prototype a personal health record application (PHA) for delivering individualized, behaviorally based physical activity interventions.
• To incorporate user-centered design principles by engaging consumers, healthcare providers, and personal trainers.
• To integrate evidence-based behavioral strategies into the PHA to promote physical activity adoption.

Main Methods:

• User-centered design approach involving facilitated group discussions and structured interviews.
• Development of a personal health record application (PHA) for sedentary adults.
• Integration of cognitive and behavioral skills such as goal-setting, self-monitoring, and relapse prevention.

Main Results:

• A functional personal health record application (PHA) was prototyped.
• The PHA successfully incorporated evidence-based behavioral interventions.
• The study demonstrated the potential of web portals for delivering research-based behavioral interventions.

Conclusions:

• Personal health record applications (PHAs) can effectively deliver individualized physical activity interventions.
• Web-based platforms offer a viable solution for consumers and providers to implement physical activity recommendations.
• This approach supports behavior change for sedentary adults, potentially reducing chronic disease risk.
