Clinical Trial Summary

The objective of this study is to investigate the feasibility of a virtually-delivered 6-month exercise and nutrition intervention in older adults with executive subjective cognitive decline (SCD). Feasibility will be determined by recruitment, retention, and adherence rates. Preliminary changes in cognition, physical function, and quality of life will be assessed as secondary outcomes. The study will recruit 140 participants aged 65 to 80 who report they feel that their memory or other thinking abilities are declining. Participants will be randomized into one of four study arms receiving different combinations of healthy lifestyle interventions. Assessments will be conducted virtually at baseline, post-intervention (6 months), and follow-up (12 months). All intervention sessions and assessment visits will be conducted online using the Zoom Healthcare platform and participants will log on using their own devices from home.


Clinical Trial Description

The study will be a randomized control trial examining the feasibility of a 6-month virtually delivered exercise and nutrition intervention in older adults with executive SCD. The study aims to recruit 140 participants. After initial contact with potential participants, 2 screening visits (up to 45 minutes each) will be conducted to assess eligibility and obtain consent to participate in the study. At the start of the program, after completing the program (6 months), and at follow-up (12 months), assessors will conduct 2 assessments (30-65 min each) using Zoom video conferencing to measure thinking abilities, physical function, and quality of life. Participants will be randomized into one of four 6-month intervention arms (35 individuals per group x 4 groups): 1) EX + DIET: aerobic and resistance exercise (EX) with healthy diet counseling (DIET), 2) EX + ED: aerobic and resistance exercise (EX) with education on healthy lifestyle related to brain health (ED), 3) STRETCH + DIET: stretching and toning exercises (STRETCH) with healthy diet counseling (DIET), 4) STRETCH + ED: stretching and toning exercises (STRETCH) with education on healthy lifestyle related to brain health (ED). All groups that receive EX and/or DIET will also receive the "Adult Strategies Put Into Real World Environments" (ASPIRE) goal strategy training, with goals focused on exercise and/or diet in order to overcome barriers and increase maintenance of lifestyle changes. All intervention sessions and assessment visits will be conducted online using the Zoom Healthcare platform, and participants will log on using their own devices from home. ;
