Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Impact 360 study will evaluate the effects of a combined intervention of exercise, mindfulness, and nutrition on 8 key indicators of health and the mechanisms that drive these changes. 60 subjects aged 50 to 75 without a current diagnosis of a brain disorder will be recruited. This study will follow a partial crossover design. All participants will receive the intervention. Participants randomized into the intervention group after their baseline screening will receive the 6-month intervention. Those randomized into the waitlist group will complete another assessment at the end of the 6-month care as usual phase before receiving the intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Current research suggests that exercise, meditation, and nutrition have neuroprotective effects although there is still a lack of pharmacological therapies to prevent or slow down disease progression. The benefits of these individual interventions have been shown, but emerging evidence suggests that combined interventions are more powerful than isolated ones. The crucial next step is to study the impact of a multimodal program on brain health and to comprehensively examine underlying mechanisms.

The comprehensive assessment ("360 degree approach") will focus on 8 key areas of health: cognition, inflammation, microbiome diversity, sleep quality, neurological imaging markers, physical fitness, cardiovascular health, and social and mental well-being. This comprehensive assessment in this healthy aging cohort will serve two purposes: 1) Help us to understand the mechanisms behind the benefits of this multimodal intervention and how the interactive effects influence one's overall health and 2) to serve as a normative dataset for replication of this study in clinical populations (e.g. Parkinson's disease, Alzheimer's disease, stroke)

The objective of this study is to explore the effects of this combined intervention on overall health. The investigators aim to discover the mechanisms of action behind the benefits of this multimodal intervention. The investigators will assess the impact of the intervention on overall health using the following 8 key indicators of overall health: cognition, inflammation and biomarkers, gut microbiome diversity, sleep quality, Magnetic Resonance Imaging (MRI) neurological markers, cardiorespiratory fitness and physical health, cardiovascular disease risk factors, and emotional well-being.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

Adults 50-75 years of age without a diagnosis of a neurodegenerative condition, will be recruited and screened for eligibility. Sixty participants will be randomly assigned to the waitlist group or the intervention group and will be striated into cohorts blocks. Each cohort block will start the intervention at the same time and will participate in the intervention together. This will allow for social interaction, engagement with their peers, and hopefully encouraging better adherence.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Exercise, Diet, Mindfulness

The intervention group will start the intervention immediately following their baseline assessment. They will undergo another assessment after the 6 month intervention period.

Group Type EXPERIMENTAL

Exercise

Intervention Type BEHAVIORAL

The intervention will involve online (via University of British Colombia (UBC) Zoom videoconferencing) 1-hour moderate to high intensity exercise classes 3 times a week for 6 months

Meditation

Intervention Type BEHAVIORAL

The intervention will involve 15 minute guided mediation following exercise classes as well as mindfulness classes.

Mindfulness classes will consist of 1.5 hour Mindfulness Based Stress Reduction (MBSR) classes for the first 2 months, followed by 1 month of 1 hour bi-weekly discussions and practice, then MBSR 2.0 for months 4 and 5, and 1 hour bi-weekly discussions and practice for the remaining month of the intervention.

Diet

Intervention Type BEHAVIORAL

The intervention will involve biweekly 1-hour nutrition and cooking classes with a dietician.

Waitlist Group

Participants randomized into the waitlist group will undergo a baseline assessment, and will then be encouraged to continue their daily activities as usual for 6 months. Physical activity and sleep will be monitored during this time using wearable devices. Links to questionnaires will be emailed monthly. After the 6-month waitlist period, participants will undergo a second assessment prior to starting the intervention. The multimodal intervention will be 6-months in length, using the same measures of adherence, and will be followed by a final assessment.

Group Type NO_INTERVENTION
