Brief summary
The INSPIRE Study, initiated by the Healthy Minds Initiative, is a community-based research project aimed at demonstrating the impact of lifestyle factors on cognitive health and the prevention of dementia. Conducted in collaboration with the American College of Lifestyle Medicine, Charles Drew University, UCLA, Stanford University and Crenshaw Christian Center, this study focuses on African American communities that are disproportionately affected by lifestyle-dependent diseases. The study involves 2,000 participants aged 55 and older and aims to directly address these disparities by implementing targeted interventions to enhance cognitive function and overall brain health.
Detailed description
The INSPIRE Study, led by the Healthy Minds Initiative, is a groundbreaking community-based research project aimed at exploring the relationship between lifestyle factors and cognitive health, with an emphasis on nutrition and dietary intervention, to prevent dementia and cognitive impairment in African American communities. This study will take place in South Los Angeles, California, a region characterized by significant health disparities, particularly in the prevalence of lifestyle-dependent diseases. The study, slated to begin in January/February 2025, will involve 2,000 participants aged 55 and older, recruited through community outreach, health education programs, and referrals from local healthcare providers. Participants will undergo a comprehensive initial assessment, including evaluations of medical history, cognitive function, lifestyle habits, and access to health resources. Participants will be randomized into two groups: an intervention group and a control group. The intervention group will receive personalized guidance from health coaches, participate in an online community forum designed to teach about nutrition and lifestyle risk factor management, and have access to tailored exercise programs, educational materials, and other resources designed to promote cognitive health. The control group will receive standard-of-care educational material and monthly communications aimed at maintaining or improving health. Both groups will undergo baseline assessments and periodic evaluations throughout the study to measure the impact of the interventions on cognitive health. The study is designed to be culturally relevant and accessible, leveraging community partnerships with organizations such as the American College of Lifestyle Medicine, Charles Drew University, UCLA, Stanford University and Crenshaw Christian Center. These partnerships provide the necessary infrastructure, expertise, and community trust to ensure the study's success. The INSPIRE Study's primary goal is to demonstrate how targeted lifestyle interventions can reduce the risk of cognitive decline in a population that is particularly vulnerable to such outcomes. By addressing factors such as diet, physical activity, stress management, and social engagement, and management of vascular risk factors, the study aims to create a model for improving brain health that can be replicated in other communities. The study's findings will not only contribute to the scientific understanding of lifestyle-related cognitive health but also have the potential to inform public health strategies and policy decisions aimed at reducing health disparities. The long-term vision is to establish the Healthy Minds Initiative as a leader in brain health equity, with the INSPIRE Study serving as a blueprint for future interventions.
Interventions
This arm involves interventions like health coaching, dietary changes, exercise programs, and other lifestyle modifications.
Participants in the Standard of Care Arm will receive basic educational materials focused on general cognitive and physical health maintenance.

Study design
Masking description
The INSPIRE Study employs a single-blind design, where participants are unaware of their group assignment (intervention or control) to minimize bias in reporting and behavior. However, the investigators and study staff administering the interventions and conducting assessments are not blinded due to the nature of the intervention, which requires direct interaction and coaching. To further reduce potential bias, outcome assessors involved in data analysis will remain blinded to the group assignments until after the primary data analysis is completed.
Intervention model description
The INSPIRE Study is a randomized controlled trial (RCT) with 2,000 participants aged 55 and older. Participants will be randomly assigned to either an intervention group, receiving a personalized, lifestyle-based program with health coaching, or a control group, receiving standard health education materials. Both groups will undergo baseline and follow-up assessments, including cognitive tests and lifestyle evaluations. The study emphasizes community engagement and culturally relevant interventions, aiming to provide insights into the impact of lifestyle changes on cognitive health and to inform public health strategies for dementia prevention in at-risk populations.
Eligibility
Inclusion criteria
* Age: Participants must be 55 years of age or older. * Ethnicity: Focused on African American individuals, but not exclusive. * Cognitive Status: Participants must have normal cognitive status, mild cognitive impairment (MCI), or subjective cognitive impairment (SCI). * Language: Participants must be fluent in English. * Location: Must reside in the Crenshaw, California area or be able to attend study-related activities in this location. * Willingness to Participate: Participants must be willing to adhere to the study protocol, including attending assessments, participating in interventions, and completing questionnaires.
Exclusion criteria
* Cognitive Decline: Diagnosis of dementia or severe cognitive impairment that would interfere with the ability to participate in the study. * Physical Limitations: Any physical or medical condition that would preclude participation in the lifestyle interventions (e.g., severe mobility issues). * Recent Cancer Diagnosis: Diagnosis of cancer within the last three years, excluding stable cases of basal cell or squamous cell carcinoma of the skin, or stable prostate cancer. * Pregnancy: Current pregnancy or planning to become pregnant during the study period. * Mental Health: Diagnosis of severe psychiatric disorders such as schizophrenia or bipolar disorder that might interfere with participation. * Substance Abuse: Current substance abuse or dependency that could impact participation. * Hearing Impairment: Uncorrected hearing loss that would limit the ability to communicate and participate in the study. * Non-English Speaking: Inability to participate in English-language oral and written cognitive assessments. * Participation in Another Study: Currently enrolled in another clinical trial that could interfere with the INSPIRE Study. * Life expectancy less than 3 years * Unwillingness to share medical and laboratory information.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Cognitive Function | 6 months, 1 year and 3 years | Change in global composite score from baseline, as measured by the TABCAT (Tablet-based Cognitive Assessment Tool) composite score, at the designated endpoint (e.g., 6 months, 1 year, and 3 years). This composite score reflects core domains of cognition-including memory, executive function, language, and processing speed-captured through standardized TABCAT assessments. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Adherence to Lifestyle Interventions | Continuous, with key evaluations at 6 months and 12 months. | Measure adherence to prescribed diet and exercise changes through self-reported questionnaires and logs maintained by health coaches. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Change in Low Density Lipoprotein (LDL) cholesterol levels | 6 months, 1 year and 3 years | Evaluate changes in Low Density Lipoprotein, as measured by a lipid panel serum test at baseline, and then at 6 months, 1 year and 3 years. |
| Executive functions composite | 6 months, 1 year and 3 years | Composite score of executive function cognitive test, as measured by TABCAT. |
| Episodic Memory Composite | 6 months, 1 year and 3 years | Composite score of episodic memory cognitive test, as measured by TABCAT. |
| Change in Hemoglobin A1c markers | 6 months, 1 year and 3 years | Evaluate changes in serum Hemoglobin A1c, a marker of glucose metabolism dysfunction, as measured in the serum, at baseline and then at 6 months, 1 year and 3 years. |
| Change in Blood Pressure | 6 months, 1 year and 3 years | Evaluate changes in blood pressure, as measured by sphygmomanometer at baseline, and then at 6 months, 1 year and 3 years. |
