Clinical Trial Summary

An accumulating body of research indicates that activities such as exercise, active cognitive and social engagement, good sleep hygiene, stress reduction and proper nutrition are associated with the maintenance of cognitive health. Emerging data also suggests that healthy lifestyle behaviors may promote brain plasticity. Despite nationwide efforts to raise public awareness about brain health, there remains a gap concerning how to best promote behavioral change and help at-risk middle-aged and older adults adopt effective, evidence-based brain health behaviors into their everyday lives to maximize cognitive health. The objective of this study is to evaluate the efficacy of a 7-week group brain fitness intervention (B-Fit) for increasing preventative brain health behaviors and enhancing cognitive health in participants at-risk for cognitive impairment. We will also examine mechanisms of action of the B-Fit intervention through tracking of behavioral responses in the real-world environment using wearable sensors.

Description:

Participants will be middle-aged and older adults. Participants will be randomized to one of three conditions (B-fit, education only, wait-list). Outcome measures will be administered at baseline, post-treatment and at a one-year follow-up. Participants will also be asked to wear an actigraph for 7 days at baseline, post intervention and follow-up. One or two clinicians will lead the intervention groups, which will each have 8-12 group members. Both the B-Fit and education control conditions will meet 2 hours per week for 7 weeks. Participants in both conditions will receive identical educational materials provided in the form of weekly learning packets and presented to the group by the study clinician(s). At the first meeting, group members will be presented with an overview of the brain, cognitive aging, mild cognitive impairment, and dementia. Each subsequent group meeting will cover a specific topic. The topics will be presented to all groups in the following order: cognitive engagement, exercise and cardiovascular risk factors, nutrition, social engagement, sleep and stress reduction, and compensatory strategy use. The control condition will include presentation of the educational materials followed by expanded discussion about the materials among group members. In contrast, each meeting of the B-Fit intervention will follow a highly structured format. The format is designed to aid participants in identifying and setting realistic and valuable individualized brain health goals and in obtaining group support through problem-solving, modeling and encouragement.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Healthy Aging Activity Engagement	(Subjective Measure) Healthy Aging Activity Engagement Scale (HAAE): participants use a 5-point Likert scale to rate level of agreement with engagement in healthy brain behaviors during the past week from strongly disagree (0) to strongly agree (5). Scores range from 32 to 160, with higher scores representing greater engagement in positive health behaviors.	Change in engagement in healthy brain aging behaviors as measured by the HAAE from baseline to post-test (appr. 2 months) and follow-up (appr. one-year).
Primary	Objective sensor-based behavior change detection with wearable sensors	(Objective Measure) Participants will wear an Actigraph for 1 week to capture objective data in the form of activity times, activity durations, mobility, activity level and sleep/time quality. We will apply the behavior change detection approach (BCD) to detect the magnitude of health-related changes in behavior patterns and to describe the nature of the changes (e.g., increased afternoon activity).	Change in activities captured by actigraphs and measured using a behavior change detection approach at baseline compared to post-test (appr. 2 months) and follow-up (appr. one-year).
Secondary	Physical Capability	The Short Physical Performance Battery (SPPB) will provide a composite measure of physical capability. The SPPB combines the results of gait speed, chair stand and balance tests.	Change in mobility as measured by the SPPB from baseline to post-test (appr. 2 months) and follow-up (appr. one-year).
Secondary	Psychological Wellbeing	The concept of psychological well-being will be captured by the NIH Toolbox surveys that measure the following three components: positive affect, general life satisfaction, and meaning and purpose. A total score will be computed.	Change in psychological wellbeing as measured by the total score of the NIH Toolbox surveys from baseline to post-test (appr. 2 months) and follow-up (appr. one-year).
Secondary	Cognitive Function	NIH Toolbox Fluid Cognition Composite Score will be used to assess for change in cognition.	Change in fluid cognitive abilities as measured by the NIH Toolbox fluid cognition composite from baseline to post-test (appr. 2 months) and follow-up (appr. one-year).
Secondary	Social Wellbeing	The concept of social wellbeing will be captured by by the NIH Toolbox surveys that measure the following components: emotional support, friendship, instrumental support, loneliness, perceived hostility, and perceived rejection. A total score will be computed.	Change in social wellbeing as measured by the total score of the NIH surveys from baseline to post-test (appr. 2 months) and follow-up (appr. one-year).
