Optimization of a Behavioral Intervention to Increase Physical Activity in Older Adults Living With HIV

Sponsor

Butler Hospital

Enrollment

196 participants

Start Date

Jun 21, 2023

Study Type

INTERVENTIONAL

Conditions

Physical Inactivity Aging HIV

Summary

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.

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).

Interventions

BEHAVIORALCognitive Behavioral Intervention for Physical Activity

Interventionist 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.

BEHAVIORALSocial Support for Physical Activity

This component will leverage the social functionality of the Fitbit app, promoting social support and friendly competition via a moderated Facebook group.

BEHAVIORALPhysical Activity Coaching

The 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.

BEHAVIORALBrief Advice and Self-Monitoring

Participants will receive a single session with brief advice about increasing physical activity, and instructions on how to use their study-provided FitBit.
