Background and objectives: The oldest adults faced the highest risk of death and hospitalization from coronavirus disease 2019 (COVID-19), but less is known about whether they also were the most likely to experience pandemic-related economic, healthcare, and mental health challenges. Guided by prior research on vulnerability versus resilience among older adults, the current study investigated age differences in economic hardship, delays in medical care, and mental health outcomes among adults aged 55 and older.

Research design and methods: Data were from the COVID-19 module and Leave Behind Questionnaire in the 2020 Health and Retirement Study (HRS). We estimated linear probability models to examine differences in experiences of pandemic-related economic and health challenges by age group (55-64, 65-74, 75+) with and without controls for preexisting sociodemographic, social program, health, and economic characteristics from the 2018 HRS. Models accounting for differential mortality also were estimated.

Results: Adults aged 65-74 and 75+ experienced fewer economic and mental health challenges and those aged 75+ were less likely to delay medical care than adults aged 55-64. Age gradients were consistent across a broad range of measures and were robust to including controls. For all age groups, economic challenges were less common than delays in medical care or experiences of loneliness, stress, or being emotionally overwhelmed.

Discussion and implications: Even though the oldest adults were at the greatest risk of death and hospitalization from COVID-19, they experienced fewer secondary pandemic-related challenges. Future research should continue to explore the sources of this resilience for older adults.

Background and objectives: Although the vulnerabilities stemming from the intersection of aging and migration are widely recognized, the migration contexts and the factors influencing the mental health of older unforced migrants have received scant attention. This review explores the drivers of unforced migrations in later life and the individual, relational, and structural factors influencing their mental health and well-being.

Research design and methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search of 7 databases for English peer-reviewed journal articles was conducted. A total of 21 studies were identified and analyzed inductively.

Results: The review classified motivations for migration as push factors and pull factors: push factors such as escaping structural inequities in the homeland and pull factors included seeking better lifestyle opportunities and reuniting with family. The positive determinants of mental health included cordial family relationships, paid employment, the presence of a partner, and strong support networks. Advanced age, absence of a partner, lifestyle changes, lack of intergenerational support, poor language proficiency, unfavorable policies, lack of access to resources, and systemic biases negatively affected the mental health of older unforced migrants.

Discussion and implications: The review highlights the need to recognize the diversity among older migrants to develop policies and programs that address their specific circumstances. Recognizing their strengths, rather than focusing solely on their vulnerabilities will help create a more positive and supportive environment, enabling them to thrive in their new communities.

Background and objectives: Cannabis use among aging Americans continues to increase. We examine correlates of cannabis use including attitudes, state of residence, health status, and service use.

Research design and methods: Using the 2018 Health and Retirement Study Cannabis module completed by 1,372 respondents aged 50 and older, we distinguished current cannabis users from those who have never used or have some prior use. We linked 2018 and 2016 core HRS data and used multinomial regressions to identify associations among current use, attitudes, place of residence, as well as current (2018) and past (2016) medical conditions, pain, and sleep issues. We also examined associations among cannabis use, hospital stays, and outpatient medical visits.

Results: Past-year cannabis use reached 10.3% among aging Americans. Attitudes toward cannabis have changed over time with 4 of 5 survey respondents currently holding a favorable attitude. Attitude and state of residence were associated with current use. Cannabis users reported higher levels of pain, were more likely to use prescription opioids, and report activity limitations in both 2016 and 2018. Associations between cannabis use and sleep issues or concurrent healthcare use were not observed.

Discussion and implications: Changing attitudes and state legalization appear important for late middle-aged and older persons, and as many as 1 of every 5 persons over 50 may be using cannabis by 2030. Cannabis use among aging Americans warrants increased attention from care providers, program administrators, and policymakers, especially as a prevention or harm reduction strategy relative to prescription opioids.

Background and objectives: Person-centered planning (PCP) allows recipients of home- and community-based service (HCBS) to plan services and supports according to their preferences and needs. The extent to which HCBS systems engage in PCP and evidence for the relationship between PCP and beneficiary outcomes are limited. We examine the prevalence of PCP among HCBS recipients and the relationship between PCP and person-reported outcomes.

Research design and methods: We used the 2018-2019 National Core Indicators-Aging and Disability survey, collected among adult Medicaid HCBS recipients in 12 states (n = 5,849). We examined 2 general PCP measures (1 on decision making and another on whether service plans reflected preferences/choices). We also constructed a scale to assess the fidelity of recipients' service planning meeting to the PCP process. Outcomes included unmet service needs and community living (i.e., participation, control, and satisfaction). We examined recipient characteristics associated with PCP and used adjusted logistic regression models to assess the relationship between PCP and outcomes.

Results: About 72% of HCBS recipients were involved in decision making, 72% reported their service plan reflected their preferences/choices, and 47% had meetings that scored "high fidelity" on the PCP fidelity scale. PCP measures were consistently related to lower likelihood of unmet service needs and greater likelihood of experiencing community living outcomes.

Discussion and implications: Findings suggest PCP is important for adequately meeting service needs and ensuring community living among HCBS beneficiaries. Additional standardized measures should be developed to facilitate quality improvement and accountability for delivering person-centered HCBS.

Background and objectives: Although coordinated care (CC) seeks to improve patient experiences and ultimately health outcomes, evidence from empirical research on the impacts of CC is mixed. This study examined the relationship between CC and healthcare outcomes over a 4-year period among older adults with multiple chronic conditions.

Research design and methods: This observational cohort study is based on data from the 2016-2020 Health and Retirement Study. Analysis is limited to respondents with 2+ chronic conditions who completed an experimental module on CC in 2016 (n = 906). Three domains of CC were assessed: perceptions, informal (family/friends) and formal (healthcare staff) tangible support, and technical support (using a "patient portal"). The longitudinal relationship between CC and health (e.g., pain, functioning, and self-rated health [SRH]) and healthcare (e.g., doctor visits, hospitalization, and care satisfaction) outcomes was investigated using mixed-effects models.

Results: Better perceptions of CC were associated with lower odds of ADL limitations (Odds ratio [OR] = 0.91; 95% CI = 0.84-0.99) and greater satisfaction with care (B = 0.04, 95% CI = 0.02-0.06). Receipt of more informal tangible support was associated with 1.34 higher odds of ADL limitations (95% CI = 1.19-1.51) and 1.74 higher odds of hospitalization (95% CI = 1.07-1.21). Use of technical support was associated with better SRH and greater satisfaction with care.

Discussion and implications: The longitudinal relationship between CC and health is multifaceted. Although positive perceptions and more technical support have beneficial effects on health outcomes, higher utilization of tangible support may reflect a higher demand among older adults with more complex healthcare needs.

Background and objectives: The primary aim of this Stage IB randomized controlled trial (RCT) was to test the preliminary effects of a dual-task exergaming telerehabilitation intervention on cognition and aerobic fitness, compared to aerobic exercise (AEx) only and attention control (stretching) in older adults with subjective cognitive decline.

Research design and methods: This RCT randomized 39 participants on a 2:1:1 allocation ratio to supervised exergame (n = 20), AEx (n = 11), and stretching (n = 8) for 12 weeks. The dual-task exergaming was concurrent moderate-intensity cycling and BrainFitRx cognitive telerehabilitation. Cognition was assessed by NIH Toolbox Cognitive Battery and aerobic fitness by 6-minute walk test (6MWT) and shuttle walk test.

Results: The participants were 74.6 (7.4) years old and 69% were female. The effect of time was significant, F(1, 23.9) = 13.16, p = .001, for the Fluid Composite score, and significant within-group changes were seen for the exergame group, t(14.08) = 2.53, p = .024, d = 0.33. Between-group changes did not reach significant levels for any cognitive test. Between-group changes for the 6MWT were not significant.

Discussion and implications: The exergame participants further improved their fluid cognition, whereas the AEx and stretching groups did not, indicating a potential synergistic effect from AEx and cognitive training. The aerobic fitness changes were similar between the exergame and AEx-only groups, indicating that the feasibility of adding cognitive training to AEx concurrently without sacrificing gains in aerobic fitness from AEx. This study shows the flexibility of exergame delivery and its potentially therapeutic effects in persons at risk for Alzheimer's dementia.

Background and objectives: Social disconnection is highly prevalent in older adults and is associated with frailty. It is unclear which aspects of social disconnection are most associated with frailty, which ones are difference-making, and which combination of social factors are directly linked to frailty.

Research design and methods: We conducted a secondary coincidence analysis (CNA) of 1,071 older adults from the Rush Memory and Aging Project (mean age 79.3 ± 7.1; 75.8% female) to identify combinations of social factors that are difference-making for frailty. We included 7 demographic (e.g., age, sex, socioeconomic status) and structural (e.g., social network), functional (e.g., social support, social activity), and quality (e.g., loneliness) aspects of social connection. An established cut score of 0.2 on a frailty index was used to define frailty as the outcome.

Results: CNA produced 46 solution models for the presence of frailty in the data set. The top-scoring model was underfit, leaving a final complex solution path for frailty with the highest fit-robustness score that met the fit parameter cutoffs. We found that the combination of loneliness, low social activity, and older age was present 82% of the time when frailty was present.

Discussion and implications: The combination of loneliness, social activity, and old age is difference-making for frailty, and supports the inclusion of social factors in frailty prevention and intervention. Further research is needed in diverse data sets to better understand the interrelationships between the 3 aspects of social connection and frailty.

Background and objectives: Despite promising effects of individualized music listening (IML) for people with dementia, the individualized nature and heterogeneity of reactions to IML remain underexplored. We aimed to develop an empirically derived typology of directly observed reactions of people with dementia to IML and propose recommendations for tailoring the intervention to the respective types.

Research design and methods: An ideal-type analysis was conducted on 108 video recordings of 45 people with mainly severe dementia (78% female, mean age of 83.02 years, all White participants) listening to recorded individualized music. Dimensions were identified for capturing similarities and differences between types.

Results: The analysis yielded 10 types of reactions ("expressing and sharing joy," "self-disclosure stimulated by music," "concentrated, absorbed listening," "blissful enjoyment," "experience of the music as bittersweet," "sharing memories," "releasing tension," "tensing up and rejecting," "predominant search for social exchange," "no interpretable reaction") and 3 dimensions ("valence" from negative to positive, "arousal" from calm to activated, "communicative activity" from defensive/resistant to proactive), resulting in a three-dimensional coordinate system, providing a holistic representation and facilitating a systematic contrast of identified reaction types to IML.

Discussion and implications: Reactions to IML were influenced by the interaction with the project staff, who monitored the sessions. Based on these observations, we propose recommendations for tailoring both the behavior of the monitoring person (e.g., engaging in synchronous activities like clapping along) and the setup of the intervention (e.g., communal vs individual listening) to each type, which may improve the effects of IML.

Background and objectives: Although it is well established that psychological disorders and osteoporosis risk are linked, how the relationship manifests is not. This study examines depressive symptoms and a history of psychological problems as potential risk factors for osteoporosis diagnosis, adjudicating between 4 theoretical models rarely tested together. We analyze these models across multiple domains (i.e., demographic, socioeconomic, and health-related), while accounting for bone mineral density (BMD) scans, which have been shown to improve health equity across sex and racial/ethnic identities.

Research design and methods: Data from the 2012-2016, nationally representative, population-based, cohort Health and Retirement Study (N = 18,224-18,359) were used to estimate 4 logistic regression models with the outcome of osteoporosis diagnosis. Approximately 50% of the sample identified as female and 50% as male, while about 81% identified as White/European American, 11% as Black/African American, and 8% as another race/ethnicity. The key independent variables were depressive symptoms-measured using two common scales-and a history of psychological problems.

Results: A history of psychological problems and one depressive symptoms measure were associated with the odds of osteoporosis diagnosis in the presence of other known risk factors for osteoporosis.

Discussion and implications: Support for the theoretical models was limited. Evidence suggests possible directionality; a history of psychological distress may be a risk factor for osteoporosis, though we cannot rule out the other direction. Public health professionals and healthcare providers should consider a history of psychological problems as a risk factor for osteoporosis when deciding whether to recommend a BMD scan.

Background and objectives: "Successful aging" as defined in Rowe & Kahn's model aims to include the major domains of aging under a single overarching concept. From here the question arises how "successful aging" itself can be implemented as an endpoint in clinical research in a way that it is compliant to methodological regulatory framework and recommendations as formulated, for example, by the FDA. This article discusses from an applied perspective approaches and examples of how "successful aging" as a multi domain concept can be put into measurement practice.

Research design and methods: Narrative literature review.

Results: Existing methods of merging insights from, e.g., functional, social, and cognitive outcomes, can fail to perform under conditions of extreme heterogeneity, as often present in samples of older adults. In research on rare diseases, the methodological approach of a Multi Domain Responder Index (MDRI) has been proposed to handle heterogeneity. MDRIs may also provide a solution to combine aging outcomes from different domains into a single "successful aging" endpoint. However, strict measurement criteria will need to be fulfilled to find acceptance in decision making and validated meaningful change thresholds are a critical prerequisite.

Discussion and implications: Gerontology can spearhead methodological approaches of handling multidimensional measurement under heterogeneity by validating a "successful aging" MDRI suitable for use as an endpoint in clinical research.
