Healthy Aging Resources to Thrive (HART)

Status Completed

Clinical Trial Summary

Healthy Aging Resources to Thrive (HART) uses a rigorous two-stage randomized control design, adapted and refined based on pilot studies, to test a novel intervention to reduce sitting time in older adults. Half the participants will be randomized to the intervention aimed at decreasing sitting time, and the other half will be randomized to a healthy living control that does not focus on reduced sitting time. After 6 months, the intervention group will be further randomized so that half continue with the intervention and the other half receive no further intervention. All participants will be followed for 12 months.

Clinical Trial Description

Healthy Aging Resources to Thrive (HART) is a two-stage randomized controlled trial (RCT) of adults over age 60 with obesity to determine the efficacy of a novel sitting-reduction intervention and its impact on cardiometabolic risk markers. Participants will be randomized to a 6-month sitting reduction intervention (termed I-STAND) or healthy-living attention control (Stage 1). All participants will be mailed a scale and a blood pressure monitor (to keep) which will be used during the phone-based measurement visits at Baseline, 3, 6 and 12 months. All participants will have phone-based Coaching sessions. After 6 months, I-STAND participants will be re-randomized to receive either booster sessions or no further intervention (Stage 2). Attention control participants will receive no further intervention. All participants will be followed for 12 months total with phone-based assessments at baseline, 3, 6, and 12 months. Primary outcomes are reduction in sitting time at 6 months, objectively measured using the activPAL device, and blood pressure. The design will answer novel questions about the impact of sitting reduction on cardiometabolic risk markers as well as maintenance of sitting reduction. UPDATE: As of 3/31/31, (final year 5) of the study, participants randomized to the i-STAND intervention will no longer be re-randomized at 6 months. We will no longer follow participants to the 12-month timepoint & will end all activities after 6-months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
