About this trial
The goal of this clinical trial is to examine 3 interventions designed to increase physical activity in older adults with HIV. We will examine 3 potential components of an intervention package: physical activity coaching, cognitive behavioral therapy targeted toward common barriers to physical activity such as low motivation or chronic pain, and a Fitbit-based social support intervention. Our primary outcome will be physical activity, defined as steps per day. Results will guide choice of intervention components to be used in an optimized behavioral intervention.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
HIV positive: defined by HIV antibody, detectable HIV RNA in plasma, or a note from the participant's HIV care provider.
Must be on continuous antiretroviral therapy (ART) for > 3 months, as assessed via self-report.
Low PA: defined as self-report of < 90 minutes of moderate-vigorous PA (MVPA) per week in the previous 3 months AND less than 14 hours per week of sustained walking in the previous 4 weeks.
Medically cleared for moderate PA. If participants report a) a history of cardiovascular disease including known coronary artery disease, peripheral vascular disease, heart failure, or stroke; or b) chest pain, shortness of breath, or dizziness or syncope either at rest or during activity in the past 3 months, then they must have medical clearance by a physician or primary care provider.
Disqualifiers
Exclusion Criteria
Medical conditions or physical or neurocognitive limitations that interfere with PA or study participation.
Hazardous substance use, assessed via a score ≥15 on the Alcohol Use Disorders Identification Test (AUDIT) or ≥6 on the Drug Abuse Screening Test (DAST).

Treatments tested in this trial
Cognitive Behavioral Intervention for Physical Activity
BehavioralInterventionist will use cognitive and behavioral techniques to help the participant increase facilitators and decrease barriers to physical activity, particularly barriers such as lack of motivation, depression, and chronic pain. Meetings will occur every other week for 4 months.
Social Support for Physical Activity
BehavioralThis component will leverage the social functionality of the Fitbit app, promoting social support and friendly competition via a moderated Facebook group.
Physical Activity Coaching
BehavioralThe PA coach will meet with the participant to set goals for physical activity (steps) and encourage self-monitoring. Meetings will occur every other week for 4 months.
Brief Advice and Self-Monitoring
BehavioralParticipants will receive a single session with brief advice about increasing physical activity, and instructions on how to use their study-provided FitBit.
