Agents of Change: Geriatrics Workforce Programs Addressing Systemic Racism and Health Equity.

Many factors affect how individuals and populations age, including race, ethnicity, and diversity, which can contribute to increased disease risk, less access to quality healthcare, and increased morbidity and mortality. Systemic racism-a set of institutional policies and practices within a society or organization that perpetuate racial inequalities and discrimination-contributes to health inequities of vulnerable populations, particularly older adults. The National Association for Geriatrics Education (NAGE) recognizes the need to address and eliminate racial disparities in healthcare access and outcomes for older adults who are marginalized due to the intersection of race and age. In this paper, we discuss an anti-racist framework that can be used to identify where an organization is on a continuum to becoming anti-racist and to address organizational change. Examples of NAGE member Geriatric Workforce Enhancement Programs (GWEPs) and Geriatrics Academic Career Awards (GACAs) activities to become anti-racist are provided to illustrate the framework and to guide other workforce development programs and healthcare institutions as they embark on the continuum to become anti-racist and improve the care and health of vulnerable older adults.

A pioneering EMR-embedded digital health literacy tool reveals healthcare disparities for diverse older adults.

BACKGROUND: The COVID-19 pandemic transformed healthcare delivery with the rapid adoption of telehealth and digital technologies to access healthcare. Interventions are needed to ensure that older people in underserved communities do not face new technology-driven healthcare disparities. This article describes pioneering electronic medical record (EMR) embedded tools to assess and support each diverse patient's digital health literacy. METHODS: We designed and validated a rapid EMR-embedded Digital Health Engagement Tool (DHET) to assess each patient's digital literacy in English and Spanish. We built a separate, EMR-generated auto-scoring function to assess patient use of telehealth and healthcare navigation as recorded within the EMR. Combined, the tools created a complete digital literacy assessment for each patient. We then deployed the tools to conduct a pilot study to elucidate disparities. RESULTS: A total of 112 ethnic/racial diverse older patients were enrolled (mean age was 78, ranging from 57 to 96) years (SD = 8.04). The female participants were 72.3%. Among the participants, non-Hispanic Whites were 47.3%; Hispanic 25.0%; non-Hispanic Asian 19.6%; non-Hispanic others (including multi-race and non-Hispanic Black/African Americans) 8.0%. Digital literacy disparities were revealed for older adults, particularly those over 70 years old, female gender, and those reporting relying on a helper. CONCLUSION: New EMR-embedded tools enable healthcare systems to assess the ability of patients to navigate and utilize EMR capabilities, such as video telehealth appointments, messaging providers, reviewing labs/radiology reports, and requesting prescriptions. The study identified significant challenges for older patients in navigating EMRs and calls for healthcare systems to better support patient learning.

Relationship Between Acculturation and Mental Health in Korean American Family Caregivers of Community-Dwelling Persons Living with Dementia.

Despite the growing number of Korean American (KA) family caregivers for persons with dementia, little is known about how acculturation might affect caregiving stress in this population. Acculturation is a variable of considerable interest in caregiving research due to its significance in understanding the impact of cultural perceptions and expectations on the caregiving role and its relation to mental health outcomes. A cross-sectional descriptive study using baseline data from an ongoing randomized controlled trial of dementia caregiver intervention was performed to examine the association between acculturation and mental health outcomes among KA caregivers (n = 32) for persons with dementia. Self-report survey questionnaires including a bidirectional acculturation scale, Center for Epidemiologic Studies Depression Scale, the Perceived Stress Scale, and the Zarit Burden Interview were administered in person in English or Korean by trained bilingual community health workers. The primary independent variable, acculturation, was assessed using a 24-item inventory. It measured two sets of cultural orientation: Korean orientation and American orientation. The mean age was 67 years (SD = 11.8) and 87% were women. Half of the caregivers were spouses of persons with dementia, while the other half were offspring caregivers. In the multiple linear regression model, caregiver acculturation toward Korean cultural orientation had a significant and positive association with depressive symptoms (ß = .62; SE = 0.25; p-value = .02) and perceived stress (ß = .29; SE = 0.13; p-value = .03) after adjusting for age and self-efficacy. No significant effect of American cultural orientation was found for caregiver burden, perceived stress, or depressive symptoms. Our findings suggest that exploring the role of acculturation in caregiving and its relation to outcomes, particularly caregiver distress, may be valuable for future studies aiming to understand specific elements of cultural values and practices in the acculturation process related to mental health outcomes among immigrant Korean American caregivers.

Boosting with variant-matched adenovirus-based vaccines promotes neutralizing antibody responses against SARS-CoV-2 Omicron sublineages in mice.

Global spread of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron subvariants, such as BA.4, BA.5 and XBB.1.5, has been leading the recent wave of coronavirus disease 2019 (COVID-19). Unique mutations in the spike proteins of these emerging Omicron subvariants caused immune evasion from the pre-existing protective immunity induced by vaccination or natural infection. Previously, we developed AdCLD-CoV19-1, a non-replicating recombinant adenoviral vector that encodes the receptor binding domain of the spike protein of the ancestral SARS-CoV-2 strain. Based on the same recombinant adenoviral vector platform, updated vaccines that cover unique mutations found in each Omicron subvariant, including BA.1, BA.2, BA.4.1 and BA.5, were constructed. Preclinical studies revealed that each updated vaccine as a booster shot following primary vaccination targeting the ancestral strain improved neutralizing antibody responses against the pseudovirus of its respective strain most effectively. Of note, boosting with a vaccine targeting the BA.1 or BA.2 Omicron subvariant was most effective in neutralization against the pseudovirus of the BA.2.75 strain, whereas BA.4.1/5-adapted booster shots were most effective in neutralization against the BQ.1, BQ1.1 and BF.7 strains. Therefore, it is imperative to develop a vaccination strategy that can cover the unique spike mutations of currently circulating Omicron subvariants in order to prevent the next wave of COVID-19.

Sleep disturbances and interrelationship between persons with dementia and family caregivers: The lived experiences of Korean American Dyads.

BACKGROUND: Little research has investigated sleep quality in dyadic interrelationships between persons with dementia (PWD) and family caregivers, particularly among immigrant ethnic minorities, such as Korean Americans. PURPOSE: The study aimed to describe lived experiences of sleep disturbances and sleep interrelationships between Korean American PWD and their family caregivers. METHODS: A descriptive qualitative design used semi-structured interviews with cohabitating PWD-caregiver dyads. RESULTS: Eleven Korean American dyads participated (PWD mean age: 82.7, SD=2.3; caregivers mean age: 69.1, SD=10.2). Major themes included (1) linked sleep disturbances between PWD and caregivers, (2) interrelationship in dyads, (3) language challenges within and outside the dyads, and (4) strategies that improve sleep quality for dyads. CONCLUSION: Findings demonstrated bidirectional influences in dyadic sleep disturbances, where caregiving reciprocally impacted PWD sleep as part of an interactional unit. Communication barriers and limited community resources posed challenges for these dyads. Future sleep interventions should consider culturally competent, dyadic approaches.

Chronic Health Conditions and Patient Portal Use in Caregivers of People With Alzheimer's Disease and Related Dementias.

This study aimed to investigate both chronic health conditions and the utilization of patient portals, focusing particularly on caregivers responsible for individuals with Alzheimer's disease and related dementias (ADRD). Data from the Health Information National Trends Survey 2018-2020 were analyzed, involving a sample of 304 family and unpaid caregivers of individuals with ADRD. Among caregivers of individuals with ADRD, 77.6% had at least one chronic disease. A significant proportion (46.6%) of ADRD caregivers had never accessed their patient portals. The limited utilization of patient portals among caregivers responsible for individuals with ADRD, particularly those with lower education, advanced age, and few chronic conditions, becomes apparent due to challenges associated with digital literacy and discomfort with computers. Recognizing the crucial role caregivers play for individuals with ADRD and their health risks, there's a need for tailored training to enhance their health management skills and caregiving capabilities.

Evaluation of immunogenicity-induced DNA vaccines against different SARS-CoV-2 variants.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in 2019 and caused the coronavirus disease 2019 (COVID-19) pandemic worldwide. As of September 2023, the number of confirmed coronavirus cases has reached over 770 million and caused nearly 7 million deaths. The World Health Organization assigned and informed the characterization of variants of concern (VOCs) to help control the COVID-19 pandemic through global monitoring of circulating viruses. Although many vaccines have been proposed, developing an effective vaccine against variants is still essential to reach the endemic stage of COVID-19. We designed five DNA vaccine candidates composed of the first isolated genotype and major SARS-CoV-2 strains from isolated Korean patients classified as VOCs, such as Alpha, Beta, Gamma, and Delta. To evaluate the immunogenicity of each genotype via homologous and heterologous vaccination, mice were immunized twice within a 3-week interval, and the blood and spleen were collected 1 week after the final vaccination to analyze the immune responses. The group vaccinated with DNA vaccine candidates based on the S genotype and the Alpha and Beta variants elicited both humoral and cellular immune responses, with higher total IgG levels and neutralizing antibody responses than the other groups. In particular, the vaccine candidate based on the Alpha variant induced a highly diverse cytokine response. Additionally, we found that the group subjected to homologous vaccination with the S genotype and heterologous vaccination with S/Alpha induced high total IgG levels and a neutralization antibody response. Homologous vaccination with the S genotype and heterologous vaccination with S/Alpha and S/Beta significantly induced IFN-γ immune responses. The immunogenicity after homologous vaccination with S and Alpha and heterologous vaccination with the S/Alpha candidate was better than that of the other groups, indicating the potential for developing novel DNA vaccines against different SARS-CoV-2 variants.

Gait and/or balance disturbances associated with Alzheimer's dementia among older adults with amnestic mild cognitive impairment: A longitudinal observational study.

AIMS: To explore whether gait and/or balance disturbances are associated with the onset of Alzheimer's dementia (AD) among older adults with amnestic mild cognitive impairment (MCI). DESIGN: This study employed a longitudinal retrospective cohort design. METHODS: We obtained data from the National Alzheimer's Coordinating Center's Uniform Data Set collected from 35 National Institute on Aging Alzheimer's Disease Research Centers between September 2005 and December 2021. The mean age of participants (n = 2692) was 74.5 years with women making up 47.2% of the sample. Risk of incident AD according to baseline gait and/or balance disturbances as measured using the Postural Instability and Gait Disturbance Score, a subscale of the Unified Parkinson's Disease Rating Scale Motor Score, was examined by the Cox proportional hazards regression models adjusting for baseline demographics, medical conditions and study sites. The mean follow-up duration was 4.0 years. RESULTS: Among all the participants, the presence or the severity of gait and/or balance disturbances was associated with an increased risk of AD. The presence or the severity of gait and/or balance disturbances was associated with a higher risk of Alzheimer's dementia among the subgroups of female and male participants. CONCLUSION: Gait and/or balance disturbances may increase the risk of developing AD, regardless of sex. IMPACT: Gait and/or balance disturbances among community-dwelling older adults with amnestic MCI may need to be frequently assessed by nurses to identify potential risk factors for cognitive decline. NO PATIENT OR PUBLIC CONTRIBUTION: Given the secondary analysis, patients, service users, caregivers or members of the public were not directly involved in this study.

Upper extremity weakness: A novel risk factor for non-cardiovascular mortality among community-dwelling older adults.

BACKGROUND: Aging-associated upper extremity weakness has been shown to be associated with adverse health outcomes in older adults, but less is known about the association between impaired upper extremity function and cause-specific mortalities. METHODS: Among the 5512 prospective community-based longitudinal Cardiovascular Health Study participants, 1438 had difficulty with one of the three upper extremity functions of lifting, reaching, or gripping. We assembled a propensity score-matched cohort in which 1126 pairs of participants with and without difficulty with upper extremity function, balanced on 62 baseline characteristics including geriatric and functional variables such as physical and cognitive function. Hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and cause-specific mortalities associated with upper extremity weakness were estimated in the matched cohort. RESULTS: Matched participants had a mean age of 73.1 years, 72.5% were women, and 17.0% African American. During 23 years of follow-up, all-cause mortality occurred in 83.7% (942/1126) and 81.2% (914/1126) of participants with and without upper extremity weakness, respectively (HR, 1.11; 95% CI, 1.01-1.22; p = 0.023). Upper extremity weakness was associated with a higher risk of non-cardiovascular mortality, occurring in 595 (52.8%) and 553 (49.1%) of participants, respectively (HR, 1.17; 95% CI, 1.04-1.31; p = 0.010), but had no association with cardiovascular mortality (30.8% vs 32.1% in those with and without upper extremity weakness, respectively; HR, 1.03; 95% CI, 0.89-1.19; p = 0.70). CONCLUSION: Among community-dwelling older adults, upper extremity weakness had a weak, albeit independent, significant association with all-cause mortality, which was primarily driven by a higher risk of non-cardiovascular mortality. Future studies need to replicate these findings and understand the underlying reasons for the observed associations.

Predicting Maximum Oxygen Uptake from Non-Exercise and Submaximal Exercise Tests in Paraplegic Men with Spinal Cord Injury.

This study aimed to develop prediction equations for maximum oxygen uptake (VO2max) based on non-exercise (anthropometric) and submaximal exercise (anthropometric and physiological) variables in paraplegic men with a spinal cord injury. All participants were tested on an arm ergometer using a maximal graded exercise test. Anthropometric variables such as age, height, weight, body fat, body mass index, body fat percentage, and arm muscle mass and physiological variables such as VO2, VCO2, and heart rate at 3 and 6 min of graded exercise tests were included in the multiple linear regression analysis. The prediction equations revealed the following. Regarding non-exercise variables, VO2max was correlated with age and weight (equation R = 0.771, R2 = 0.595, SEE= 3.187). Regarding submaximal variables, VO2max was correlated with weight and VO2 and VCO2 at 6 min (equation R = 0.892, R2 = 0.796, SEE = 2.309). In conclusion, our prediction equations can be used as a cardiopulmonary function evaluation tool to estimate VO2max simply and conveniently using the anthropometric and physiological characteristics of paraplegic men with spinal cord injuries.

A Study on Rehabilitation Specialists' Perception of Experience with a Virtual Reality Program.

This study aimed to analyse the types and characteristics of rehabilitation specialists' experience in administering virtual reality (VR) programs using Q methodology as well as provide basic data regarding the introduction of VR programs in rehabilitation therapy. Thirty-three statements were derived based on a literature review and an in-depth interview with rehabilitation specialists. Q-sorting was performed by a Q-sample of 22 rehabilitation specialists with experience administering VR programs. Data were analysed using the QUANL Program. Rehabilitation specialists' experience with administering VR programs were classified into three types: type 1 was labelled 'the need to develop VR programs customised for disability level and type', type 2 was labelled 'emphasis on experts' role of paying attention continuously and their experience', and type 3 was labelled 'the need to develop safety equipment by disability type'. The study's findings demonstrate that there are a variety of rehabilitation specialists' perceptions on their experience administering VR programs. This study is of significance because it suggests ways to improve VR programs for disabled people, with the consultation of rehabilitation specialists. In addition, rehabilitation specialists' perceptions on VR programs have not been explored before.

Recombinant measles virus encoding the spike protein of SARS-CoV-2 efficiently induces Th1 responses and neutralizing antibodies that block SARS-CoV-2 variants.

Owing to the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants, the development of effective and safe vaccines has become a priority. The measles virus (MeV) vaccine is an attractive vaccine platform as it has been administered to children for more than 40 years in over 100 countries. In this study, we developed a recombinant MeV expressing the full-length SARS-CoV-2 spike protein (rMeV-S) and tested its efficacy using mouse and hamster models. In hCD46Tg mice, two-dose rMeV-S vaccination induced higher Th1 secretion and humoral responses than one-dose vaccination. Interestingly, neutralizing antibodies induced by one-dose and two-dose rMeV-S immunization effectively blocked the entry of the α, ß, γ, and δ variants of SARS-CoV-2. Furthermore, two-dose rMeV-S immunization provided complete protection against SARS-CoV-2 in the hamster model. These results suggest the potential of rMeV-S as a vaccine candidate for targeting SARS-CoV-2 and its variants.

The Effectiveness of Language-Specific Personal Care Education on Improving the Knowledge and Skills of Vietnamese American In-Home Supportive Service Caregivers.

BACKGROUND: In-Home Supportive-Services (IHSS) caregivers provide personal care assistance to low-income older adults. According to the California Social Service Department, 20.2% of IHSS caregivers spoke Vietnamese in one county. The purpose of this project was to improve the knowledge and skills among these Vietnamese American caregivers by providing a language-specific and culturally appropriate education on personal care. METHODS: The project used a pre- and post-test design. Under the guidance of nursing faculty, four Vietnamese-speaking nursing students provided a 2-hr educational program on personal care (e.g., bathing, oral care) to registered Vietnamese IHSS caregivers. A pre- and post-survey was conducted. RESULTS: Overall, 55 caregivers completed the surveys. The surveys showed significant increases in confidence in knowledge and skills related to personal care topics (all ps < .001). CONCLUSION: The findings demonstrated that the cultural and language-specific education was effective in increasing knowledge and confidence of Vietnamese IHSS caregivers related to personal care for older adults.

Individual socioeconomic status and risk of out-of-hospital cardiac arrest: A nationwide case-control analysis.

OBJECTIVES: Area-level socioeconomic status (SES) is associated with the incidence of out-of-hospital cardiac arrest (OHCA); however, the effects of individual-level SES on OHCA occurrence are unknown. This study investigated whether individual-level SES is associated with the occurrence of OHCA. METHODS: This case-control study used data from the nationwide OHCA registry and the National Health Information Database (NHID) in Korea. All adult patients with OHCA of a medical etiology from 2013 to 2018 were included. Four controls were matched to each OHCA patient based on age and sex. The exposure was individual-level SES measured by insurance type and premium, which is based on income in Korea. National Health Insurance (NHI) beneficiaries were divided into four groups (Q1-Q4), and medical aid beneficiaries were separately classified as the lowest SES group. The adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for the outcomes were calculated. Stratified analyses were conducted according to age and sex. RESULTS: A total of 105,443 cases were matched with 421,772 controls. OHCA occurred more frequently in the lower SES groups. Compared with the highest SES group (Q1), the aORs for OHCA occurrence increased as the SES decreased (aORs [95% CI] were 1.21 [1.19-1.24] for Q2, 1.33 [1.31-1.36] for Q3, 1.32 [1.30-1.35] for Q4, and 2.08 [2.02-2.13] for medical aid). Disparity by individual-level SES appeared to be greater in males than in females and greater in the young and middle-aged adults than in older adults. CONCLUSIONS: Low individual-level SES was associated with a higher probability of OHCA occurrence. Efforts are needed to reduce SES disparities in the occurrence of OHCA.

Pioneering COVID-19 Pandemic Partnerships: Federally Qualified Health Centers and Geriatric Workforce Enhancement Programs Work Together to Care for Diverse Underserved Older Adults.

Background: The COVID-19 pandemic disproportionately affected populations served by Federally Qualified Health Centers (FQHCs), with high morbidity and mortality rates in ethnic minority older adults. In response to this pandemic, academic geriatric medicine teams through federally funded Geriatric Workforce Enhancement Program (GWEP) with FQHC partnership implemented new initiatives to improve the care for vulnerable older adults. Objectives: To describe how four FQHC/GWEP teams collaborated in caring for diverse communities of older adults during the pandemic. Methods: Four GWEPs have addressed pandemic response efforts with their respective FQHC partners. These collaborations to meet the increasing numbers of older adults seeking services, and the rising disparities exacerbated during the pandemic are delineated. Results: FQHC/GWEP partnerships enabled access to care, whether in-person or virtually to serve unmet needs of underserved older adults during the pandemic. Partnerships promoted COVID-19 education, testing, and vaccinations. Most FQHCs faced severe staffing shortages, and the digital divide challenged patients with barriers. GWEPs provided direct care, created educational materials, and developed telehealth programs. These partnerships addressed social determinants of health gaps caused by the pandemic. Conclusion: The findings demonstrate that strong partnerships between GWEPs and FQHCs mitigate health inequities for vulnerable ethnic minority and rural older adults during pandemic crises.

A novel conceptual model of trauma-informed care for patients with post-acute sequelae of SARS-CoV-2 illness (PASC).

AIM: This paper proposes a novel, trauma-informed, conceptual model of care for Post-Acute Sequelae of COVID-19 illness (PASC). DESIGN: This paper describes essential elements, linkages and dimensions of the model that affect PASC patient experiences and the potential impact of trauma-informed care on outcomes. DATA SOURCES: PASC is a consequence of the global pandemic, and a new disease of which little is known. Our model was derived from the limited available studies, expert clinical experience specific to PASC survivors and publicly available social media narratives authored by PASC survivors. IMPLICATIONS FOR NURSING: The model provides a critical and novel framework for the understanding and care of persons affected by PASC. This model is aimed at the provision of nursing care, with the intention of reducing the traumatic impacts of the uncertain course of this disease, a lack of defined treatment options and difficulties in seeking care. The use of a trauma-informed care approach to PASC patients can enhance nurses' ability to remediate and ameliorate both the traumatic burden of and the symptoms and experience of the illness. CONCLUSION: Applying a trauma-informed perspective to care of PASC patients can help to reduce the overall burden of this complex condition. Owing to the fundamentally holistic perspective of the nursing profession, nurses are best positioned to implement care that addresses multiple facets of the PASC experience. IMPACT: The proposed model specifically addresses the myriad ways in which PASC may affect physical as well as mental and psychosocial dimensions of health. The model particularly seeks to suggest means of supporting patients who have already experienced a life-threatening illness and are now coping with its long-term impact. Since the scope of this impact is not yet defined, trauma-informed care for PASC patients is likely to reduce the overall health and systems burdens of this complex condition.

A Culturally and Linguistically Appropriate Telephone Support Intervention for Diverse Family Caregivers of Persons With Dementia During the COVID-19 Pandemic.

Caregivers of persons with dementia (PWDs) were socially isolated with little support during the COVID-19 pandemic "Stay-At-Home" order in the United States. To enhance social and emotional connection for diverse caregivers, a culturally/linguistically appropriate telephone intervention provided compassionate listening, mindful breathing, and COVID-19 safety education. The study purpose was to understand caregiving challenges and to evaluate the intervention for caregivers during the early pandemic using a qualitative approach. Twenty-three caregivers participated in the intervention provided by bilingual research assistants for 3 months. Call logs were used to describe the caregivers' dialogue. Thematic analysis identified (a) the challenges, including fear of coronavirus disease, providing around-the-clock care, and forced isolation and negative emotions; and (b) caregivers' experience with the intervention, including connecting with the outside, relief from emotional stress, reliable COVID-19 information, and reinformed caregiving skills. Results suggest that the telephone support was of benefit to diverse caregivers of PWDs during the pandemic by promoting social connection and reducing emotional distress.

Immunogenicity of candidate SARS-CoV-2 DNA vaccines based on the spike protein.

Coronavirus disease 2019 caused by the novel human severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently a major threat to public health worldwide. To deal with the needs of vaccine, we developed four DNA vaccine candidates against SARS-CoV-2, based on the full-length spike (S) or truncated S protein. Following mice vaccination, we measured T-cell response and antigen-specific neutralizing antibody (NAb) titer. All four candidates induced humoral immune responses, including elevated levels of total IgG and NAbs, and cell-mediated immune responses, including multiple cytokine expression. However, the full-length S DNA vaccine enhanced the immune responses most significantly. We then evaluated its appropriate antigen dose and vaccination schedule. Although all immunized groups showed higher immune response than the control group, inoculation with 50 µg antigen led to the highest NAb titer. Immunity was significantly increased after the third inoculation. Thus, the full-length S DNA vaccine can potentially prevent SARS-CoV-2 infection.

Association of adherence to high-intensity physical activity and the Mediterranean-dietary approaches to stop hypertension intervention for neurodegenerative delay diet with cognition: A cross-sectional study.

BACKGROUND: Prevention is a priority in the absence of a cure for dementia. Physical activity and a neuroprotective diet such as the Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay (MIND) diet are healthy lifestyle behaviors that may slow the onset of dementia. However, research on the relationship between the combination of physical activity and the MIND diet and cognition is rare. OBJECTIVES: The purpose of this study was to investigate whether the combination of high-intensity physical activity and the MIND diet is associated with better cognition compared with either behavior alone or neither behavior. DESIGN: A population-based, cross-sectional study was conducted using data from the Health and Retirement Study. METHODS: Using information from a total of 3463 participants (age 68.0 ±â€¯10.0 years), multivariate linear regression models and binary logistic regression models with interaction terms between high-intensity physical activity (PA) and the MIND diet (MIND) were used to assess associations of PA and MIND with global cognition and odds of cognitive decline. Group comparisons were conducted among four groups: PA-/MIND-, PA+/MIND-, PA-/MIND+, and PA+/MIND+. RESULTS: PA+/MIND- did not predict cognitive outcomes (versus PA-/MIND-). PA-/MIND+ was associated with better global cognition (mean difference [d] = 0.81; 95% confidence interval [CI] = 0.50-1.11; p < 0.001) and lower odds of cognitive decline (odds ratio [OR] = 0.68; 95% CI = 0.54-0.86; p = 0.001) (versus PA-/MIND-). PA+/MIND+ predicted better global cognition (d = 0.98; 95% CI = 0.59-1.36; p < 0.001) and lower odds of cognitive decline (OR = 0.69; 95% CI = 0.50-0.94; p = 0.004) (versus PA-/MIND-). PA+/MIND+ was associated with better global cognition (d = 0.60; 95% CI = 0.08-1.12; p < 0.001), but did not predict lower odds of cognitive decline (versus PA+/MIND-). PA+/MIND+ did not predict cognitive outcomes (versus PA-/MIND+). CONCLUSIONS: Combining high-intensity physical activity and the MIND diet was associated with better cognitive health than high-intensity physical activity alone or non-adherence to both behaviors. To potentially exert additive effects, it will be important to encourage these two healthy habits. More research on the role of combined physical activity and dietary change is necessary to further inform policy and clinical guidance.
