The Promotion of Physical Activity for the Prevention of Alzheimer's Disease in Adults With Down Syndrome
November 28, 2023 updated by: University of Kansas Medical Center
The objectives of this study are to determine the feasibility and potential efficacy of remotely delivered group exercise sessions to increase daily moderate to vigorous physical activity in adults with Down syndrome, relative to a usual care control.
Participants will be randomized to attend 40 min remotely delivered group moderate to vigorous physical activity (MVPA) sessions at low frequency (1 session/wk.,RL),
high frequency (3 sessions/wk., RH), or usual care control usual care control (UC).
In addition to the group MVPA sessions, participants in both the RL and RH groups will also receive a step counter, access to resources for increasing MVPA, and one 20-min remotely delivered individual support/education session/wk.
Content for both the RL and RH arms will be identical with the exception of group session frequency (1 vs. 3/wk.).
Participants in the UC arm will receive a step counter, access to resources for increasing MVPA, and monthly remote individual support/education).The primary aim is to Assess daily MVPA (min) in the RL, RH, and UC arms at baseline, 3, 6, 9, and 12 mos., and obtain effect sizes for change in MVPA over 12-mos.Secondary Aim 1 is to assess the impact of MVPA on cardiovascular fitness, quality of life, cognitive function, and brain parameters related to Alzheimer's Disease (whole and regional brain volume, functional connectivity, and cerebral blood flow) at baseline, 6, and 12 mos.
Secondary Aim 2 will determine the feasibility (retention, session attendance, use of recorded sessions (RH/RL only) of RL, RH, and UC interventions.

Detailed Description
This research study will compare 3 strategies for the delivery of an intervention to increase moderate to vigorous physical activity (MVPA) in community dwelling adults with Down Syndrome; remotely delivered group MVPA sessions at low (1 session/wk.,RL),
high frequency (3 sessions/wk., RH), or usual care control (UC).
Adults (age ≥ 18 yrs.)
with Down Syndrome will be randomized (2:2:1) to one of the 3 intervention arms for an 12-mo.
trial.
Cohorts of ~20 adults with Down Syndrome will be recruited and computer randomized.
Participants will be stratified by sex and sequentially randomized by the study statistician.
Participants in all arms will be provided with an iPad for intervention delivery, Fitbit for self-monitoring MPA, and will be asked to complete 150 min of MPA/wk.
Participants in the RL and RH arms will be asked to complete 40 minutes MVPA sessions delivered via Zoom software on an iPad, RL will be provided 1 session/wk, and RH will be provided 3 sessions/wk.
Participants in both the RL and RH groups will also receive one 20-min remotely delivered individual support/education session/wk.
with a heath coach to discuss progress and provide support.
The UC intervention will follow the traditional approach to promote increased MVPA.
Participants will receive an iPad tablet loaded with information regarding increasing MVPA and will also receive resistance bands and a Fitbit for self-monitoring MVPA.
Monthly 20-min.
education/support sessions, identical to the education/support sessions provided in the RL and RH arms, will be delivered to participants and their caregivers remotely on the iPad using FaceTime.
All outcomes will be collected by trained research assistants who are blinded to the study condition.
The primary outcome, daily MVPA (min) in the RL, RH, and UC arms will be assessed at baseline, 3, 6, 9, and 12 mos.
using an accelerometer.
All secondary outcomes will be assessed at baselines, 6, and 12 months.
Secondary outcomes are to assess the impact of MVPA across the RL, RH, and UC arms on cardiovascular fitness, quality of life, cognitive function and brain parameters related to Alzheimer's Disease (whole and regional brain volume, functional connectivity, cerebral blood flow).
Additionally the researchers will determine the feasibility (retention, session attendance, use of recorded sessions (RH/RL only) and safety of RL, RH, and UC arms.
