A Dyadic Approach for a Remote Physical Activity Intervention in Adults With AD and Their Caregivers

Summary

The objective of this study is to compare the effectiveness of 2 intervention delivery strategies for increasing moderate physical activity (MPA), real-time group video conferencing (RGV) vs. enhanced usual care (EUC), in community dwelling adults with Alzheimer's diseases (AD) and their caregiver (dyads) over 18 mos. (6 mos. active, 6 mos. maintenance, 6 mos. no contact). The primary outcome is to compare total MPA (min/wk.), assessed using ActiGraph, in adults with AD from baseline to 6 mos. Secondary aims for the Adults with AD are to compare MPA (min/wk), sedentary time (min/wk.), percentage meeting 150 min/wk. goal, functional fitness, activities of daily living (basic/instrumental), quality of life, residential transitions, and cognitive function across 18 months between RGV and EUC. Secondary aims for the caregivers are to compare total MPA (min/wk.), sedentary time (min/wk.), functional fitness, quality of life, caregiver burden across 18 months between RGV and EUC. Additionally, as an exploratory aim, this study will evaluate the influence of process variables/participant characteristics on MPA in adults with AD and their caregiver across 6, 12 \& 18 mos.: age, sex, BMI, attendance (exercise/support sessions), use of recorded videos, PA self-monitoring, peer interactions during group sessions, caregiver support, type and quality of dyadic relationship, and number of caregivers.

• Alzheimer Disease

Interventions

BEHAVIORAL

Real-time Group Video

Dyads in the RGV arm will be asked to complete three 45 min sessions that include aerobic, resistance, and balance/coordination exercises delivered by a trained health coach via Zoom® software on an iPad during mos. 0-6, and 1 session/wk. during mos. 7-12 to groups of 5-8 dyads in their home along with being provided written materials regarding exercise and physical activity from the National Institute on Aging and brief (15-20 min) FaceTime meetings (0-6 mos.= 2/mo.; 7-12 mos.= 1/mo.) with the heath coach to discuss progress, provide support and receive additional guidance on how to increase MPA.

BEHAVIORAL

Enhanced Usual Care

Dyads in the EUC arm, will be given a recommended exercise plan to follow on their own along with being provided written materials regarding exercise and physical activity from the National Institute on Aging and brief (15-20 min) FaceTime meetings (0-6 mos.= 2/mo.; 7-12 mos.= 1/mo.) with the heath coach to discuss progress, provide support and receive additional guidance on how to increase MPA.
