CORRELATIONS AMONG SLEEP BIOMETRICS, DAILY STEPS, AND SELF-REPORTED FUNCTION IN OLDER COUPLES WITH AND WITHOUT MCI
Authors: Alimohammadbeik Kourosh , Jacelon Cynthia 
Published: January 2025

Abstract
Altered sleep patterns are common among older individuals and those with Mild Cognitive Impairment (MCI). Sleep changes can lead to fatigue, and alterations in physical and social function. In couples, disrupted sleep of one partner can affect the other’s sleep patterns. We compared measures of sleep and steps, captured by actigraph, with self-reported fatigue, physical function, and social roles among cognitively intact couples, and those with one partner who had MCI. The WHO International Classification of Functioning, Disability, and Health was the framework. Using a correlational design, we compared biometric measures with scales on the PROMIS 29 at three points in time in 13 couples &gt;70 years old. Eight couples had one partner who scored &lt; 25 on the MoCA. Significance was set at P =0.05. In cognitively intact couples, total and deep sleep time were correlated with fatigue (negative) and social roles. Deep sleep time was associated with physical function. Bedtime and time awake were correlated with fatigue (negative) and social roles. In couples with MCI, total and deep sleep time were associated with fatigue (negative). Steps correlated with physical activity, fatigue (negative), and social roles. Time awake was positively associated with fatigue. Bedtime and number of awakenings were associated with social role (negative). Sleep quality and steps have significant effects on self-reported function of couples with and without MCI. Total and deep sleep time were most important for cognitively intact couples, and number of steps was most important for couples with MCI.

Authors: He Chanchan , Jiang Nan , Chen Ke , Yu Yue , Xiao Yexuan 
Published: January 2025

Abstract

Background
Digital interventions aim to improve outcomes in irreversible Mild Cognitive Impairment (MCI) with limited evidence on effective strategies. This review evaluates the effectiveness of such interventions through randomized controlled trials (RCTs), identifying key characteristics of success.

Methods
The search was conducted on CINAHL, Embase, MEDLINE, PubMed, PsycINFO, and grey literature from January 1, 2010, to November 20, 2023, to identify randomized controlled trials that examined the effects of digital interventions on global cognitive function outcomes in individuals with MCI. Mean differences and standard deviations of neuropsychological assessment scores were extracted to derive standardized mean differences.

Results
Out of 2,859 studies, 19 were analyzed. Digital interventions improved global cognitive function in MCI patients (SMD (95% CI) = 0.40 (0.22-0.59)), executive function (-0.48 (-0.76 to -0.21)) and attention (0.39 (0.16-0.61)). Four critical factors contribute to the success of these interventions: (1) Ease of use; (2) Opportunities for social interactions; (3) Human support; (4) Engagement in physical exercises; and (5) interventions tailored to the participants’ needs. Additionally, methodological considerations for future randomized controlled trials on digital MCI interventions include: (1) Inclusion of both a healthy control group and an intervention group with clinically diagnosed MCI; (2) Collecting support-related data throughout the intervention period; (3) Assessing intervention success qualitatively and quantitatively; (4) Conducting follow-up interviews and surveys up to 1-year post-intervention to evaluate long-term outcomes.

Conclusion
The insights from this systematic review empower future digital MCI intervention researchers, health professionals, clinicians, and patients to design, develop, and implement successful interventions for older users.
NEIGHBORHOOD DISORDER AND COGNITIVE HEATH: THE CAUSAL MEDIATING EFFECTS OF ALLOSTATIC LOAD AND PHYSICAL ACTIVITIES
Authors: Yu Jiao , Wang Yi , Chen Xi 
Published: January 2025

Abstract
Numerous studies have attempted to establish a link between neighborhood disorder and later life cognitive decline, with stress accumulation and reduced physical activity hypothesized as potential mediators. However, there remains a significant gap in our understanding of the causal mechanisms underlying this link. This research utilizes data from the Health and Retirement Study (2006-2008 and 2010-2012) to investigate whether stress accumulation, as measured by allostatic load, and physical activity mediate the association between perceived neighborhood disorder and cognitive health. Older Americans aged 65 years and older without dementia at baseline were selected (n=4,346). Cognitive function was measured using the Telephone Interview for Cognitive Status (TICS). Employing propensity score matching followed by causal mediation analyses, we find that higher levels of perceived neighborhood disorder at baseline are associated with poorer cognitive health at a subsequent wave. Under a counterfactual framework, if every respondent had experienced one standard deviation above the mean level of neighborhood disorder, the cognitive score would be 0.68 lower than the score if everyone had experienced one standard deviation below the mean (total effect: -0.68, 95% CI: -0.94, -0.42). Approximately three percent (natural indirect effect = -0.02, 95% CI: -0.04, -0.01) of this effect is attributable to physical activity. Notably, we find no significant mediating effect of allostatic load (natural indirect effect = -0.005, 95% CI: -0.02, 0.004) after adjusting for individual-level characteristics. Our findings underscore the significant role of the behavioral factor in mediating the relationship between disadvantaged neighborhoods and cognitive health among older adults.
PREDICTING MILD COGNITIVE IMPAIRMENT AND DEMENTIA: MACHINE LEARNING VERSUS TRADITIONAL METHODOLOGIES

Published: January 2025

Abstract
Although mild cognitive impairment (MCI) faces significant challenges in terms of early diagnosis and intervention, machine learning (ML) shows promise in managing complex data for MCI and dementia prediction. This study assessed and compared the predictive accuracy of ML models with traditional logistic regression in identifying MCI and dementia onset using the Korean Longitudinal Study of Aging (KLoSA) dataset. The sample comprised 4,975 older adults aged 60 years or older. Identification of MCI and dementia relied on self-reported diagnoses with sociodemographic, lifestyle, and health-related variables as key covariates. The dataset was categorized into training and test sets to predict MCI and dementia, employing models such as logistic regression, light gradient-boosting machine, XGBoost, CatBoost, and Random Forest. Shapley additive explanation values were used to determine the contribution of each feature to the prediction rate. Logistic regression excelled in predicting dementia onset, whereas XGBoost performed better in predicting MCI (XGBoost AUC: 0.7271; Random Forest AUC: 0.6741). Increased assets reduced MCI risk, however, lower education, reduced activities of daily living functional ability, and pain in daily life increased MCI risk. Predictors of developing dementia were being female, older age, reduced activities of daily living functional ability, and lower education. The ML algorithms, particularly XGBoost, demonstrated potential for predicting MCI onset using KLoSA data. This study underscores the crucial role of sociodemographic factors in the early prediction and prevention of cognitive impairment. By leveraging readily available sociodemographic and health-related characteristics, more cost-effective and targeted interventions can be provided to at-risk community-dwelling older adults.
RACIAL/ETHNIC DIFFERENCES IN SUBJECTIVE COGNITIVE DECLINE SYNDROMES
Authors: Jacobs Moyosoreoluwa , Lichtenberg Peter , Tarraf Wassim 
Published: January 2025

Abstract
Subjective cognitive decline (SCD) is a precursor to Alzheimer’s Disease and Related Dementias (ADRD). SCD rates vary by race/ethnicity. SCD is also heterogenous in the population and can yield different syndromes. We used Behavioral Risk Factor Surveillance System data (2015/2016 and 2019/2020) from non-Hispanic White (NHW), Black (NHB), and Hispanic individuals aged 50+ years (unweighted-n=44,152) who endorsed SCD, to fit latent class analysis (LCA) and derive SCD syndromes based on measures of activities limitations, need for assistance, and consulting with healthcare providers. We used multinomial logistic regression to model differences in syndrome prevalence by R/E and assess the contributions of predisposing (e.g., age), enabling (e.g., insurance), and health need (E.g., cardiovascular) factors to explaining these racial/ethnic (R/E) differences. Three groupings (social limitations [13.3%], mixed functional limitations [26.2%] and uncomplicated [60.5%]) fit the data well. Compared to NHWs (21.9%), Hispanics and NHBs were significantly more likely to meet criteria for mixed functional limitations [38.2% and 41.2% respectively] and less likely to be in the uncomplicated group. Predisposing, enabling, and health need factors only partially attenuated (10-22%) the Relative Risk Ratios for classification in the mixed functional limitations for NHBs and Hispanics. Hispanics and NHBs presented with more mixed SCD-related functional limitations compared to NHWs, suggesting higher risk for developing ADRDs. Since nearly 2/3 individuals in the mixed functional limitations group reported discussing SCD with healthcare providers, there are opportunities to provide interventions for this high risk group at their place of care, and reduce R/E disparities in SCD and ADRD.

Abstract
Individuals with cognitive impairment have common cardiometabolic comorbidities; however, their prevalence trends remain unknown. We aimed to address this knowledge gap by selecting participants with cognitive impairment from the Health and Retirement Study. Cognitive status was evaluated using the validated Telephone Interview for Cognitive Status (TICS), categorizing participants into normal cognition (TICS≥12), mild cognitive impairment (MCI) (TICS 7-12), and dementia (TICS &lt; 7). The study analyzed data from 40,170 participants with cognitive impairment, with an average age of 73.4±11.2 years. Between 1996 and 2018, there was an observed increase in the prevalence of hypertension, diabetes, and stroke among adults with dementia and MCI. Specifically, hypertension prevalence rose from 60.5% to 77.0% in the dementia group and from 55.7% to 72.9% in the MCI group, diabetes prevalence increased from 21.8% to 37.9% among those with dementia and from 19.1% to 34.5% among those with MCI, and stroke prevalence escalated from 13.5% to 18.0% in the dementia group and from 8.7% to 12.3% in the MCI group. Conversely, heart disease prevalence decreased in individuals with dementia (from 35.3% to 32.2%) but slightly increased in those with MCI (from 28.4% to 29.6%). Our study found that adults with dementia or MCI had an increased prevalence trend in hypertension, diabetes, and stroke over the past two decades, although those with dementia had a decreased prevalence trend in heart disease. Further action is needed to reduce the cardiometabolic burden in this vulnerable population.
WHAT TYPES OF SUPPORT BURDENED DEMENTIA CAREGIVERS LOOK FOR?
Authors: Hwang Yeji , Cho Hannah 
Published: January 2025

Abstract
As dementia caregivers provide excessive amount of care daily to persons living with dementia, many caregivers feel physical or emotional burden. However, lack of information is available on what kind of support that caregivers seek for when they feel physical or emotional burden. Therefore, this study aimed to investigate support that burdened dementia caregivers look for. We conducted a secondary data analysis of the National Study of Caregiving (NSOC) IV, focusing on caregivers of persons living with possible or probable dementia (n=518). Descriptive data analyses, chi square tests, and logistic regression analyses were performed for data analysis. In this study, when caregivers felt emotional burden (42%), they were more likely to use service that take care of the care recipient so that they could take some time away from caregiving (OR= 3.160, p=0.001) or find paid helper to do household chores or personal care (OR= 2.259, p=0.004). Similarly, when caregivers felt physical burden (23.98%), they were more likely to use service that take care of the care recipient so that they could take some time away from caregiving (OR= 3.050, p=0.004) or find paid helper to do household chores or personal care (OR= 2.651, p=0.006). Other support such as support group or training for caregivers did not show any significance. This study found dementia caregivers seek support services when they feel emotional or physical burden. Policy makers should consider these services readily accessible to dementia caregivers.
RECOLLECTING AND REFLECTING: STORY ASIDES IN YOUNG AND OLDER ADULTS’ AUTOBIOGRAPHICAL STORIES
Authors: McCune Teagan , Alea Nicole 
Published: January 2025

Abstract
The ways people tell autobiographical stories changes with age. One change is the amount of tangentially-related information included in these stories. These pieces of information–story asides–add context (e.g. knowledge about the world or storyteller). Story asides are expressed more frequently in the autobiographical stories of older adults compared to young adults, but the underlying mechanism is unclear. One potential mechanism is how people remember the story. The current study tested two potential mediators of this expression in young and older adults’ autobiographical stories. As part of a larger study, 61 young (M = 19.9 years) and 35 older (M = 73.8 years) adults shared an autobiographical story about the same event, a positive vacation. Participants then completed a modified version of the Autobiographical Memory Questionnaire, including 5 items about recollection (e.g., feeling the emotions they felt then) and 3 items about reflection (e.g., how significant this event is) on their autobiographical story. Mediation regression analyses indicated that story aside expression, recollecting about events, and reflecting on events all increased with increasing age. However, recollection and reflection did not predict story asides, nor were there any mediating effects of these variables between age and story aside expression in autobiographical stories. These findings suggest the way people remember and reflect on their stories is perhaps not an underlying mechanism for age group differences in story aside expression. If not the subjective indicators of memory quality and experience (recollection, reflection), then other cognitive and goal-oriented variables might explain these changes.

Published: January 2025

Abstract
Evaluation is the cornerstone of demonstrating a particular project’s success and paving the way for continuous improvement. However, most of the existing evaluation in social service sector focused on outcome, whereas some evaluated process and a very few included both process and outcome evaluation. Logic models have been found useful in programme evaluation but little is known about how to construct and apply logic models for guiding the process and outcome evaluation of community-based projects, and even less for projects with academic-NGO partnership. A pilot project adopting a carer-centric approach has been launched in 2023, which is anticipated to serve carers and older adults with caring needs in the district-based caregiver support units operated by five NGO partners in Hong Kong. This paper reports how the university as a project partner constructs a comprehensive logic model for evaluation through engaging different stakeholders (including NGO partners, funder, and potential beneficiaries) in two rounds of small group semi-structured interview. Deductive approach is applied for thematic analysis using MAXQDA to identify and prioritize inputs, activities, outputs, and outcomes of the project at initiate phase. Findings provide academics, NGOs and funding bodies with fresh insights into new elements of logic model, including volunteers as important inputs, co-creation workshops as important activities for project positioning and service alignment, number of referral cases as important outputs, and experience consolidation for service adjustment as important intermediate outcomes. This study highlights that process and outcome evaluation can be advanced by promoting stakeholder engagement to co-construct logic model.
COMPARISON OF ENERGY AND NUTRIENT INTAKE WITH DIETARY GUIDELINE OF RURAL ELDERS AND ITS CONTACT WITH OXIDATIVE STRESS
Authors: Shi Jing , Ning Yanhua , Kong Weijuan 
Published: January 2025

Abstract
The aging in rural areas has surpassed that in urban areas, becoming increasingly severe, and the health status of the older should be of concern. Diet and nutrient intake are important influencing factors for the occurrence and development of chronic diseases, and are currently relatively easy to control. Previous studies have shown that oxidative stress is a common pathogenic mechanism of chronic diseases. This cross sectional study invited 376 older residents from 3 rural communities to complete a dietary survey and collect blood samples for calculating dietary intake and laboratory testing of oxidative stress levels, respectively. Compared the energy and nutrient intake of the participants with recommendation in the Dietary Guidelines, and employed latent analysis based on whether the intake meets the recommended. The results revealed three classes, “imbalanced nutrient-high energy” (37.50%, imbalanced in intake of energy and nutrients with high energy and protein intake), “sufficient nutrient-low energy and protein” (18.35%, sufficient and balanced intake of other nutrients except for energy and protein), and “low nutrient” (44.15%, low intake of energy and various nutrients). Among the oxidative stress biomarkers, imbalanced nutrient-high energy had higher value than did the other classes for 8-iso-PGF2α; sufficient nutrient-low energy and protein valued higher than imbalanced nutrient-high energy and low nutrient classes for SOD. Oxidative stress can be measured based on the different classes of energy and nutrient intake classes and their predictors.

Published: January 2025

Abstract

Intro
Latine family caregivers of persons living with Alzheimer’s disease and other related dementias (ADRD) need access to culturally congruent support services. Interventions incorporating community engagement have shown effectiveness in providing ADRD-specific education, supporting caregivers, and mitigating accessibility concerns (transportation and meeting occupational demands).

Methods
Data was collected via structured conversations (World Cafe style discussions) with youth, adult caregivers, and older adults (n=52) on their perspectives, needs, and preferences about aging and dementia needs in the community. Data were coded deductively and analyzed via directed content analysis.

Results
Latine community members shared their interest in developing a community-engaged program that addressed training on health conditions, emphasized the importance of patience and compassion in dementia caregiving, and language concerns. Content analysis revealed community youth emphasizing interpersonal connection and integration of older adults with the broader community; adult caregivers suggesting a need for caregiver self-care and the mitigation of daily scheduling conflicts; and older adults emphasizing need for emotional support, respectful communication, and language barriers in medical, occupational, and service environments. Implications: Community-engaged feedback is vital in developing interventions reflecting Latine community needs and cultural values. Culturally responsive interventions are necessary because they integrate community member experiences and needs while concurrently promoting community ownership over the research process.

Abstract
Health promotion for community-dwelling older adults is necessary to facilitate aging in place as the world moves towards an aging society. Substantial efforts have been made to increase the participation of older adults in health promotion programs; however, they were often fragmented due to a lack of active participation of older adults and stakeholders in community settings. This project aimed to co-create a health promotion program for older adults in the community within a care living lab focusing on the five principles: co-creation, engaging end-users and stakeholders, multiple methods, and real-life settings. Older adults as end-users and stakeholders were included in the co-creation of the health promotion program. Multiple methods, such as workshops, meetings, and interviews, were conducted within the existing community program. In total, 37 older adults, 19 frontline staff members, and stakeholders engaged in the co-creation process. The health promotion program ultimately included education for dementia, insomnia, and falls, cognitive worksheets, and exercise, which improved the level of frailty in older adults. The developed program was applied to another group of older adults, effectively improving their physical and cognitive functions, as well as their quality of life. Satisfaction with the program was high, and frontline staff reported positive experiences with the co-creation process. The health promotion program, developed within the care living lab, improved older adults’ health status and brought positive experiences among both older adults and staff. The living lab can be an effective method to improve older adults’ health status by facilitating co-creation and engagement.
