Abstract
This article describes the public health impact of Alzheimer's disease (AD), including prevalence and incidence, mortality and morbidity, use and costs of care and the ramifications of AD for family caregivers, the dementia workforce and society. The Special Report discusses the larger health care system for older adults with cognitive issues, focusing on the role of caregivers and non-physician health care professionals. An estimated 6.9 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060, barring the development of medical breakthroughs to prevent or cure AD. Official AD death certificates recorded 119,399 deaths from AD in 2021. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death in the United States. Official counts for more recent years are still being compiled. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2021, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 140%. More than 11 million family members and other unpaid caregivers provided an estimated 18.4 billion hours of care to people with Alzheimer's or other dementias in 2023. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $346.6 billion in 2023. Its costs, however, extend to unpaid caregivers' increased risk for emotional distress and negative mental and physical health outcomes. Members of the paid health care and broader community-based workforce are involved in diagnosing, treating and caring for people with dementia. However, the United States faces growing shortages across different segments of the dementia care workforce due to a combination of factors, including the absolute increase in the number of people living with dementia. Therefore, targeted programs and care delivery models will be needed to attract, better train and effectively deploy health care and community-based workers to provide dementia care. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2024 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $360 billion. The Special Report investigates how caregivers of older adults with cognitive issues interact with the health care system and examines the role non-physician health care professionals play in facilitating clinical care and access to community-based services and supports. It includes surveys of caregivers and health care workers, focusing on their experiences, challenges, awareness and perceptions of dementia care navigation.

Lawson KM, Sutin AR, Atherton OE, Robins RW. Are trajectories of personality and socioeconomic factors prospectively associated with midlife cognitive function? Findings from a 12-year longitudinal study of Mexican-origin adults. Psychol Aging 2023; 38:749-762.

Abstract
Problems with memory, executive function, and language are a significant public health concern, especially when they begin during midlife. However, there is relatively little work on risk and protective factors for cognitive function in middle adulthood. Using data from 883 Mexican-origin adults assessed up to 6 times across 12 years (Mage at Time 1 = 38.2 years; range = 27-63 years), the present study examined whether developmental trajectories (levels and slopes) of Big Five personality domains and socioeconomic factors (per capita income, economic stress) were prospectively associated with cognitive function (memory, mental status, verbal fluency) at the final assessment. We found that individuals with higher levels of, and smaller decreases in, Neuroticism had worse cognitive function 12 years later. Further, individuals with higher initial Conscientiousness had better subsequent memory, mental status, and verbal fluency, and individuals with higher Openness and Extraversion had better subsequent verbal fluency (but not memory or mental status). The trajectories of per capita income and economic stress were robustly associated with cognitive function, such that higher initial levels and greater increases in socioeconomic resources had protective associations, whereas higher levels and greater increases in economic stress had deleterious associations with cognitive function. Higher education level was associated with better cognitive function 12 years later. These findings suggest that changes in personality and socioeconomic factors across adulthood are associated with cognitive function, which may be informative for interventions to support healthier cognitive aging starting at least as early as midlife.

Abstract
Background and Objectives Diabetes is common among Hispanic older adults; however, the association between diabetic complications and pain has not been widely studied in this population. Our objective was to examine the association between diabetes complications and pain over 6 years among Mexican Americans aged 80 years and older. Research Design and Methods We used data from Waves 7 to 9 (2010-2016) of the Hispanic Established Population for the Epidemiologic Study of the Elderly (n = 853). Participants were categorized as having no diabetes, diabetes without complications, and diabetes with complications. Pain was defined as reporting pain when standing or walking (pain on weight-bearing) and having pain that limited daily activities (pain interference). We used generalized estimating equations to estimate the odds of pain over 6 years as a function of diabetes status controlling for socioeconomic and health characteristics. Results At baseline, the mean age was 85.7 (standard deviation = 3.9) years, 65.2% female, 68.5% had no diabetes, 14.7% had diabetes without complications, and 16.9% had diabetes with complications. Those with diabetes without complications had lower odds of reporting pain on weight-bearing and pain interference, compared to those with no diabetes. Among those reporting diabetes (n = 269), those with complications had higher odds of pain on weight-bearing and pain interference, compared to those without complications. Those with both micro and macro complications had over 2 times the odds of pain, compared to those having no complications. Discussion and Implications The lower burden of pain in those with diabetes but no complications may reflect optimal management of diabetes. Routine screening and treatment of pain in patients with diabetes complications can mitigate excess disability and increase the quality of life for patients with diabetes.

Abstract
Alzheimer's Disease (AD) continues to be a leading cause of death in the US. As the US aging population (ages 65 +) expands, the impact will disproportionately affect vulnerable populations, e.g., Hispanic/Latino population, due to their AD-related health disparities. Age-related regression in mitochondrial activity and ethnic-specific differences in metabolic burden could potentially explain in part the racial/ethnic distinctions in etiology that exist for AD. Oxidation of guanine (G) to 8-oxo-guanine (8oxoG) is a prevalent lesion and an indicator of oxidative stress and mitochondrial dysfunction. Damaged mtDNA (8oxoG) can serve as an important marker of age-related systemic metabolic dysfunction and upon release into peripheral circulation may exacerbate pathophysiology contributing to AD development and/or progression. Analyzing blood samples from Mexican American (MA) and non-Hispanic White (NHW) participants enrolled in the Texas Alzheimer's Research & Care Consortium, we used blood-based measurements of 8oxoG from both buffy coat PBMCs and plasma to determine associations with population, sex, type-2 diabetes, and AD risk. Our results show that 8oxoG levels in both buffy coat and plasma were significantly associated with population, sex, years of education, and reveal a potential association with AD. Furthermore, MAs are significantly burdened by mtDNA oxidative damage in both blood fractions, which may contribute to their metabolic vulnerability to developing AD.

Acceptability and Feasibility of a Socially Enhanced, Self-Guided, Positive Emotion Regulation Intervention for Caregivers of Individuals With Dementia: Pilot Intervention Study. JMIR Aging 2023; 6:e46269. [PMID: 37672311 PMCID: PMC10512116 DOI: 10.2196/46269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 06/04/2023] [Accepted: 06/20/2023] [Indexed: 09/07/2023] Open
Abstract
BACKGROUND The responsibilities of being a primary caregiver for a loved one with dementia can produce significant stress for the caregiver, leading to deleterious outcomes for the caregiver's physical and psychological health. Hence, researchers are developing eHealth interventions to provide support for caregivers. Members of our research team previously developed and tested a positive emotion regulation intervention that we delivered through videoconferencing, in which caregiver participants would meet one-on-one with a trained facilitator. Although proven effective, such delivery methods have limited scalability because they require significant resources in terms of cost and direct contact hours. OBJECTIVE This study aimed to conduct a pilot test of a socially enhanced, self-guided version of the positive emotion regulation intervention, Social Augmentation of Self-Guided Electronic Delivery of the Life Enhancing Activities for Family Caregivers (SAGE LEAF). Studies have shown that social presence or the perception of others in a virtual space is associated with enhanced learning and user satisfaction. Hence, the intervention leverages various social features (eg, discussion boards, podcasts, videos, user profiles, and social notifications) to foster a sense of social presence among participants and study team members. METHODS Usability, usefulness, feasibility, and acceptability data were collected from a pilot test in which participants (N=15) were given full access to the SAGE LEAF intervention over 6 weeks and completed preintervention and postintervention assessments (10/15, 67%). Preliminary outcome measures were also collected, with an understanding that no conclusions about efficacy could be made, because our pilot study did not have a control group and was not sufficiently powered. RESULTS The results suggest that SAGE LEAF is feasible, with participants viewing an average of 72% (SD 42%) of the total available intervention web pages. In addition, acceptability was found to be good, as demonstrated by participants' willingness to recommend the SAGE LEAF program to a friend or other caregiver. Applying Pearson correlational analyses, we found moderate, positive correlation between social presence scores and participants' willingness to recommend the program to others (r9=0.672; P=.03). We also found positive correlation between social presence scores and participants' perceptions about the overall usefulness of the intervention (r9=0.773; P=.009). This suggests that participants' sense of social presence may be important for the feasibility and acceptability of the program. CONCLUSIONS In this pilot study, the SAGE LEAF intervention demonstrates potential for broad dissemination for dementia caregivers. We aim to incorporate participant feedback about how the social features may be improved in future iterations to enhance usability and to further bolster a sense of social connection among participants and study staff members. Next steps include partnering with dementia clinics and other caregiver-serving organizations across the United States to conduct a randomized controlled trial to evaluate the effectiveness of the intervention.

Abstract
Objective To investigate the association between Latinx older adults' stroke, multimorbidity, and caregiver burden. Methods For this retrospective cohort study, we used the Hispanic Established Populations for the Epidemiologic Study of the Elderly (H-EPESE) Wave-7 data set. The caregiver's physical burden was defined by using the Level of Burden Index. The caregiver's psychological burden was measured by using the Perceived Stress Scale (PSS-4). Multimorbidity was defined as the presence of 3 or more chronic conditions. Results The average age of the Latinx adults was 86 years, and the caregivers were 56 years. Latinx older adults and caregivers were more likely to be females (66% and 75%). Most caregivers were children (71%). Twelve percent of Latinx older adults presented with stroke, and 50% presented with multimorbidity. Caregiver physical burden was stratified into 3 levels: low (43%), medium (17%), and high (40%) burden. The cumulative logit model revealed that caregivers caring for those with stroke or multimorbidity had a high physical burden. Family caregivers and caregivers with a higher household income had a low physical burden. Caregivers with multimorbidity had a higher psychological burden. Caregivers who were interviewed in Spanish and those with higher household incomes had decreased psychological burden. Conclusion This study revealed that caregivers had a higher physical burden among caregivers of Latinx adults with stroke or multimorbidity. Future studies must investigate the relationship between Latinx adults' stroke and caregiver psychological health, and build culturally tailored policies and community interventions to support caregivers susceptible to high stress and burden.

Abstract
This study investigated to what extent socioeconomic status (SES) disparity associates with cognitive and physical impairment within older Asian Americans in comparison with other races/ethnicities. Data were from the National Health and Nutrition Examination Survey 2011-2018 that included 3,297 White, 1,755 Black, 1,708 Hispanic, and 730 Asian Americans aged ≥ 60. Physical functioning was measured by activities of daily living (ADL) or instrumental activities of daily living (IADL). Memory and language fluency were evaluated using the Alzheimer's Disease Word List Memory Task and Animal Fluency Tests, respectively. Multivariate logistic regressions were conducted to investigate the association between SES and physical and cognitive impairment within racial/ethnic groups, and seemingly unrelated regressions compared coefficients across subgroups. Asians with ≤ high school education had the highest prevalence of age- and sex-adjusted memory impairment among all races/ethnicities, while no difference was observed for those with > high school education. ADL/IADL disability odds did not differ between Asians and Whites, but Asians were more likely to exhibit impaired verbal fluency. Education disparity for ADL disability (OR, 3.40; 95% CI, 2.20-5.25) and memory impairment (OR, 11.57; 95% CI, 6.59-20.31) were largest among Asians compared to Whites, Blacks, and Hispanics. Income disparity for function impairment showed no significant difference across racial/ethnic groups (all P > 0.05). Asians experienced the highest burden of physical functioning and memory impairment due to education disparity. Efforts should focus on strengthening research infrastructure and creating targeted programs and services to improve cognitive and physical health for racially/ethnically underrepresented older adults with lower education attainment.

Longitudinal Analysis of Social Isolation and Cognitive Functioning among Hispanic Older Adults with Sensory Impairments. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6456. [PMID: 37568997 PMCID: PMC10419238 DOI: 10.3390/ijerph20156456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Revised: 07/13/2023] [Accepted: 07/18/2023] [Indexed: 08/13/2023]
Abstract
OBJECTIVES Understanding the intersection of age, ethnicity, and disability will become increasingly important as the global population ages and becomes more diverse. By 2060, Hispanics will comprise 28% of the U.S. POPULATION This study examines critical associations between sensory impairment, social isolation, and cognitive functioning among Hispanic older adults. METHODS Our sample consisted of 557 Hispanic older adults that participated in Rounds 1-3 or Rounds 5-7 of the National Health and Aging Trends Study. Longitudinal mediation models across a three-year span were estimated using Mplus, with vision, hearing, and dual sensory impairments predicting cognitive functioning directly and indirectly through social isolation. RESULTS Findings indicated that cognitive functioning was concurrently and, in certain cases, longitudinally predicted by vision and dual sensory impairments and by social isolation. Contrary to expectations, vision and hearing impairments were not predictive of social isolation. Dual sensory impairment was associated with social isolation, yet no significant indirect associations were found for sensory impairments predicting cognitive functioning through social isolation. DISCUSSION The finding that social isolation did not mediate the relationship between sensory impairment and cognitive decline among Hispanic older adults in the U.S. is contrary to findings from other studies that were not specifically focused on this population. This finding may be evidence that culturally motivated family support and intergenerational living buffer the impact of sensory impairments in later life. Findings suggest that Hispanic older adults experiencing dual sensory impairments may benefit from interventions that foster social support and include family members.

Abstract
This article describes the public health impact of Alzheimer's disease, including prevalence and incidence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society. The Special Report examines the patient journey from awareness of cognitive changes to potential treatment with drugs that change the underlying biology of Alzheimer's. An estimated 6.7 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060 barring the development of medical breakthroughs to prevent, slow or cure AD. Official death certificates recorded 121,499 deaths from AD in 2019, and Alzheimer's disease was officially listed as the sixth-leading cause of death in the United States. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2019, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 145%. This trajectory of deaths from AD was likely exacerbated by the COVID-19 pandemic in 2020 and 2021. More than 11 million family members and other unpaid caregivers provided an estimated 18 billion hours of care to people with Alzheimer's or other dementias in 2022. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $339.5 billion in 2022. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Members of the paid health care workforce are involved in diagnosing, treating and caring for people with dementia. In recent years, however, a shortage of such workers has developed in the United States. This shortage - brought about, in part, by COVID-19 - has occurred at a time when more members of the dementia care workforce are needed. Therefore, programs will be needed to attract workers and better train health care teams. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2023 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $345 billion. The Special Report examines whether there will be sufficient numbers of physician specialists to provide Alzheimer's care and treatment now that two drugs are available that change the underlying biology of Alzheimer's disease.

Abstract
We investigated the association of social strain from friends, depression, and systemic inflammation (C-Reactive Protein [CRP]) with cognitive impairment without dementia (CIND) and dementia among 9,262 participants (age ≥ 65). We analyzed data from the Health Retirement Study (HRS), performing Chi-squared and logistic regression analyses. Measures included the 27-point HRS cognition scale, social strain scale, Center for Epidemiological Studies Depression scale, and dried-blood CRP levels. Black and Hispanic participants had a significantly increased dementia risk (OR = 2.69 and OR = 2.54). Black participants also had a high risk of CIND (OR = 2.80), but no association of Hispanic participants with CIND. Increased social strain from friends and depression were significantly associated with CIND (OR = 1.50 and OR = 1.44) and dementia (OR = 1.57 and OR = 1.78). Elevated CRP levels were only linked to CIND risk (OR = 1.03), not dementia. Early detection and interventions targeting social strain, depression, and CRP levels may help promote cognitive functioning in older adults.

Abstract
INTRODUCTION Few studies have examined the impacts of neighborhood SES and individual ethnicity and SES characteristics on cognitive function in aging populations. Hispanics/Latinx are more likely to have cognitive impairment and be community dwellers than non-Hispanic Whites. Neighborhood factors can have greater impacts on the relationship between Hispanics/Latinx and cognitive function. This study examines these relationships in Nueces County, Texas. METHODS A mixed-effects regression analysis of data from 1,140 older adults participating in the Brain Attack Surveillance in Corpus Christi - Cognitive project from 2018 to 2020 was completed. Cognitive function was measured with the Montreal Cognitive Assessment, a cognitive screening measure. Participant addresses were geocoded to obtain census tracts, which were proxies for neighborhoods. Neighborhood SES was measured by household median income, percentage of Hispanic/Latinx residents, and percentage of residents aged ≥65 years with Medicaid, all from the American Community Survey. Interactions were used to examine the impact of neighborhood SES on ethnicity and cognitive function. RESULTS The sample consisted of 62.5% Hispanic/Latinx and 37.5% non-Hispanic White participants. Results from the F-statistics, test of effects, indicate that being older (F4,1138=45.04; p<0.001), being a man (F1,1130=4.35; p<0.050), having low education (F3,1121=40.83; p<0.001), completing the Montreal Cognitive Assessment test in Spanish (F1,1140=15.35; p<0.001), and being Hispanic/Latinx (F1,962=20.84; p<0.001) were all associated with lower Montreal Cognitive Assessment scores. Neighborhood income was positively associated (F1,69.6=6.95; p<0.050) with Montreal Cognitive Assessment scores. Neighborhood income (β=0.32; p<0.050) and percentage with Medicaid (β=0.06; p<0.050) independently moderated the associations between ethnicity and Montreal Cognitive Assessment scores. CONCLUSIONS Findings suggest that neighborhood SES could further impact cognitive function independent of individual characteristics. This could be attributed to minimal resources in communities with lower SES, impacting policies and programs for older individuals, particularly those with worse cognitive function.

Abstract
Mexican Americans (MA) are more likely to have cognitive impairment and dementia (CID), be diagnosed at an earlier age and live with CID longer, compared to non-Hispanic Whites (NHW). While studies have examined unmet needs of individuals with CID and their caregivers, few have focused on MA populations in the U.S. This paper examines the needs of community-residing individuals with CID and their caregivers in Nueces County, Texas, a county with one of the largest MA populations in the U.S., while exploring ethnic differences in needs identified. Using concept mapping, a mixed-method approach, qualitative input on perceived needs by informal caregivers and health professionals was collected. Participants then sorted and rated perceived needs. Using this information, multidimensional scaling and cluster analyses were conducted to map the relationship between perceived needs and determine their importance and priority. Five clusters were derived for caregivers and four for the health professionals. Themes across both caregivers and health professionals highlighted the need for specialized and team-based medical care, caregiver support and training, along with socio-economic and physical needs that help with day-to-day care of individuals with CID. Among caregivers, MA rated financial resources as more important and of higher priority compared to NHW. The health professionals' perspectives were aligned with those of all caregivers. By understanding the needs of caregivers and individuals with CID, we can help families deal with this disease and let caregivers thrive. This is especially important for minority populations like MAs.

Abstract
Thus far, the prevalence and correlates of obesity among the oldest have been identified in several studies. Nevertheless, there is a lack of a systematic review, meta-analysis and meta-regression synthesizing the existing observational studies. Consequently, our aim was to fill this knowledge gap. Three electronic databases were searched (Medline, PsycINFO, CINAHL) and an additional hand search was performed. Observational studies (both, cross-sectional and longitudinal) determining the prevalence and (preferably) the correlates of obesity in the oldest old (≥80 years) were included. Data extraction covered study design, measurement of obesity, analytical approach, sample characteristics and main results. In total, 19 studies were included. Reported prevalence of obesity in the community varied greatly (range 0.7%-71.5%). The pooled prevalence of obesity was 17.8% (95% CI: 13.3%-22.2%), with significant heterogeneity between studies (I2 = 99.7%, P < 0.001). There is evidence of a publication bias. Meta-regressions showed that some of the heterogeneity was explained by the types of measures of obesity and country of the respective sample. In conclusion, obesity remains a key challenge among the oldest old. Future research in this age bracket is urgently required in regions mostly neglected thus far (e.g., South America, Africa or Asia). Moreover, studies based on longitudinal data are required to clarify the determinants of obesity among the oldest old. Furthermore, studies based on objectively recorded obesity (e.g., waist circumference) are also required. Geriatr Gerontol Int 2022; 22: 373-383.

FRONTIERS IN PAIN RESEARCH 2022; 3:830308. [PMID: 35399155 PMCID: PMC8983931 DOI: 10.3389/fpain.2022.830308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 02/24/2022] [Indexed: 11/13/2022] Open
Abstract
Introduction Multimorbidity, the co-occurrence of two or more chronic conditions, is common among older adults and is associated with decreased quality of life, greater disability, and increased mortality. Yet, the association of multimorbidity with pain, another significant contributor to decreased quality of life, has not been widely studied. This is especially understudied among very old (aged ≥ 80) Mexican Americans, a fast-growing segment of the United States (US) population. Objective To assess the association of multimorbidity with pain in very old Mexican Americans, over six years of follow-up. Methods We used data from Waves 7 (2010/2011) to 9 (2015/2016) of the Hispanic Established Populations for the Epidemiologic Study of the Elderly, a longitudinal study of older Mexican Americans residing in the Southwestern US. Multimorbidity was defined as reporting two or more chronic health conditions. Pain was defined as (1) pain on weight-bearing, (2) pain in back, hips, knees, ankles/feet, legs, entire body, or two or more locations, and (3) pain that limits daily activities. We use generalized estimation equations to estimate the odds ratio of pain as a function of multimorbidity over 6 years. Results At baseline (n = 841), 77.3% of participants had multimorbidity. Those with multimorbidity had greater odds [2.27, 95% confidence interval (CI): 1.74, 2.95] of reporting pain on weight-bearing over time, compared to those without multimorbidity. Also, those with multimorbidity had 2.12 times the odds of reporting pain that limited their daily activities (95% CI: 1.61, 2.78) compared to those without multimorbidity. Lastly, those with multimorbidity had higher odds of reporting pain in their back, knee, ankles/feet, legs, hips, entire body, or two or more locations, compared to those without multimorbidity. Conclusions Those with multimorbidity consistently had higher odds of all types of pain, highlighting the need for early management of pain among those with multiple chronic conditions and complex health needs. This is especially important among very old Mexican Americans, who have a high burden of chronic health conditions.

Abstract
This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society. The Special Report discusses consumers' and primary care physicians' perspectives on awareness, diagnosis and treatment of mild cognitive impairment (MCI), including MCI due to Alzheimer's disease. An estimated 6.5 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060 barring the development of medical breakthroughs to prevent, slow or cure AD. Official death certificates recorded 121,499 deaths from AD in 2019, the latest year for which data are available. Alzheimer's disease was officially listed as the sixth-leading cause of death in the United States in 2019 and the seventh-leading cause of death in 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2019, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 145%. More than 11 million family members and other unpaid caregivers provided an estimated 16 billion hours of care to people with Alzheimer's or other dementias in 2021. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $271.6 billion in 2021. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Members of the dementia care workforce have also been affected by COVID-19. As essential care workers, some have opted to change jobs to protect their own health and the health of their families. However, this occurs at a time when more members of the dementia care workforce are needed. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2022 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $321 billion. A recent survey commissioned by the Alzheimer's Association revealed several barriers to consumers' understanding of MCI. The survey showed low awareness of MCI among Americans, a reluctance among Americans to see their doctor after noticing MCI symptoms, and persistent challenges for primary care physicians in diagnosing MCI. Survey results indicate the need to improve MCI awareness and diagnosis, especially in underserved communities, and to encourage greater participation in MCI-related clinical trials.

Abstract
OBJECTIVE We designed an mHealth application (app) user interface (UI) prototype informed by participatory design sessions, persuasive systems design (PSD) principles, and Lorig and Holman's self-management behavior framework to support self-management activities of Hispanic informal dementia caregivers and assessed their perceptions and preferences regarding features and functions of the app. MATERIALS AND METHODS Our observational usability study design employed qualitative methods and forced choice preference assessments to identify: (1) the relationship between user preferences for UI features and functions and PSD principles and (2) user preferences for UI design features and functions and app functionality. We evaluated 16 pairs of mHealth app UI prototype designs. Eight paper-based paired designs were used to assess the relationship between PSD principles and caregiver preferences for UI features and functions to support self-management. An Apple iPad WIFI 32GB was used to display another 8 paired designs and assess caregiver preferences for UI functions to support the self-management process. RESULTS Caregivers preferred an app UI with features and functions that incorporated a greater number of PSD principles and included an infographic to facilitate self-management. Moreover, caregivers preferred a design that did not depend on manual data entry, opting instead for functions such as drop-down list, drag-and-drop, and voice query to prioritize, choose, decide, and search when performing self-management activities. CONCLUSION Our assessment approaches allowed us to discern which UI features, functions, and designs caregivers preferred. The targeted application of PSD principles in UI designs holds promise for supporting personalized problem identification, goal setting, decision-making, and action planning as strategies for improving caregiver self-management confidence.

Abstract
The clinical presentation and the pathological processes underlying Alzheimer's disease (AD) can be very heterogeneous in severity, location, and composition including the amount and distribution of AB deposition and spread of neurofibrillary tangles in different brain regions resulting in atypical clinical patterns and the existence of distinct AD variants. Heterogeneity in AD may be related to demographic factors (such as age, sex, educational and socioeconomic level) and genetic factors, which influence underlying pathology, the cognitive and behavioral phenotype, rate of progression, the occurrence of neuropsychiatric features, and the presence of comorbidities (e.g., vascular disease, neuroinflammation). Heterogeneity is also manifest in the individual resilience to the development of neuropathology (brain reserve) and the ability to compensate for its cognitive and functional impact (cognitive and functional reserve). The variability in specific cognitive profiles and types of functional impairment may be associated with different progression rates, and standard measures assessing progression may not be equivalent for individual cognitive and functional profiles. Other factors, which may govern the presence, rate, and type of progression of AD, include the individuals' general medical health, the presence of specific systemic conditions, and lifestyle factors, including physical exercise, cognitive and social stimulation, amount of leisure activities, environmental stressors, such as toxins and pollution, and the effects of medications used to treat medical and behavioral conditions. These factors that affect progression are important to consider while designing a clinical trial to ensure, as far as possible, well-balanced treatment and control groups.

Abstract
Extensive literature in the United States documents racial/ethnic and gender disparities in the incidence and prevalence of dementia yet few studies have examined how race/ethnicity and gender intersect to shape inequalities in the risk of dementia. Moreover, few studies have examined heterogeneity in the contribution of known risk factors to dementia across these demographic strata while properly accounting for the semi-competing risk of death. I calculated the proportion of dementia cases attributable to socioeconomic, lifestyle, and medical risk factors across demographic subgroups using nationally representative data from the US-based Health and Retirement Study for the years 2000-2016 and a multistate framework that accounts for the semi-competing risk of death. Socioeconomic resources contributed to the largest number of dementia cases but the magnitude of this contribution varied across strata defined by race/ethnicity and gender. The greatest potential for dementia prevention was observed among non-Hispanic black and Hispanic men and women, supporting an intersectionality approach, and underscoring the need for culturally sensitive intervention and public health initiatives to address the growing burden of dementia. Taken together, work demonstrates the potential benefit of taking an intersectional approach to understanding disparities in dementia.

Abstract
BACKGROUND Dementia is often underdiagnosed and this problem is more common among some ethnoracial groups. OBJECTIVE The objective of this study was to examine racial and ethnic disparities in the timeliness of receiving a clinical diagnosis of dementia. RESEARCH DESIGN This was a prospective cohort study. SUBJECTS A total of 3966 participants age 70 years and above with probable dementia in the Health and Retirement Study, linked with their Medicare and Medicaid claims. MEASURES We performed logistic regression to compare the likelihood of having a missed or delayed dementia diagnosis in claims by race/ethnicity. We analyzed dementia severity, measured by cognition and daily function, at the time of a dementia diagnosis documented in claims, and estimated average dementia diagnosis delay, by race/ethnicity. RESULTS A higher proportion of non-Hispanic Blacks and Hispanics had a missed/delayed clinical dementia diagnosis compared with non-Hispanic Whites (46% and 54% vs. 41%, P<0.001). Fully adjusted logistic regression results suggested more frequent missed/delayed dementia diagnoses among non-Hispanic Blacks (odds ratio=1.12; 95% confidence interval: 0.91-1.38) and Hispanics (odds ratio=1.58; 95% confidence interval: 1.20-2.07). Non-Hispanic Blacks and Hispanics had a poorer cognitive function and more functional limitations than non-Hispanic Whites around the time of receiving a claims-based dementia diagnosis. The estimated mean diagnosis delay was 34.6 months for non-Hispanic Blacks and 43.8 months for Hispanics, compared with 31.2 months for non-Hispanic Whites. CONCLUSIONS Non-Hispanic Blacks and Hispanics may experience a missed or delayed diagnosis of dementia more often and have longer diagnosis delays. When diagnosed, non-Hispanic Blacks and Hispanics may have more advanced dementia. Public health efforts should prioritize racial and ethnic underrepresented communities when promoting early diagnosis of dementia.

Abstract
Alzheimer's disease and Alzheimer's disease-related dementias (AD/ADRD) disproportionally affect Hispanic and Latino populations, yet Hispanics/Latinos are substantially underrepresented in AD/ADRD clinical research. Diverse inclusion in trials is an ethical and scientific imperative, as underrepresentation reduces the ability to generalize study findings and treatments across populations most affected by a disease. This paper presents findings from a narrative literature review (N = 210) of the current landscape of Hispanic/Latino participation in clinical research, including the challenges, facilitators, and communication channels to conduct culturally appropriate outreach efforts to increase awareness and participation of Hispanics/Latinos in AD/ADRD clinical research studies. Many challenges identified were systemic in nature: lack of culturally relevant resources; staffing that does not represent participants' cultures/language; eligibility criteria that disproportionately excludes Hispanics/Latinos; and too few studies available in Hispanic/Latino communities. The paper also details facilitators and messaging strategies to improve engagement and interest among Hispanics/Latinos in AD/ADRD research, starting with approaches that recognize and address the heterogeneity of the Hispanic/Latino ethnicity, and then, tailor outreach activities and programs to address their diverse needs and circumstances. The needs identified in this article represent longstanding failures to improve engagement and interest among Hispanics/Latinos in AD/ADRD research; we discuss how the field can move forward learning from the experiences of the COVID-19 pandemic.

Unpaid dementia caregiving was valued at $256.7 billion in 2020. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are more than three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 23 times as great. Total payments in 2021 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $355 billion. Despite years of efforts to make health care more equitable in the United States, racial and ethnic disparities remain - both in terms of health disparities, which involve differences in the burden of illness, and health care disparities, which involve differences in the ability to use health care services. Blacks, Hispanics, Asian Americans and Native Americans continue to have a higher burden of illness and lower access to health care compared with Whites. Such disparities, which have become more apparent during COVID-19, extend to dementia care. Surveys commissioned by the Alzheimer's Association recently shed new light on the role of discrimination in dementia care, the varying levels of trust between racial and ethnic groups in medical research, and the differences between groups in their levels of concern about and awareness of Alzheimer's disease. These findings emphasize the need to increase racial and ethnic diversity in both the dementia care workforce and in Alzheimer's clinical trials.

Abstract
Importance: Rural-dwelling Latinos are an underresourced population in need of accessible and effective wellness programs. Objective: To evaluate patients’ long-term health-related outcomes after lifestyle intervention. Design: An uncontrolled pilot trial assessing change in health from pretreatment to long-term follow-up (12 mo after intervention completion, no contact) and from posttreatment to long-term follow-up. Setting: Rural, community-based primary care. Participants: Latino and Hispanic safety-net primary care patients, ages 50 to 64 yr. Intervention: A culturally tailored, 4-mo lifestyle intervention co-led by occupational therapy practitioners and Latino community health workers that features telehealth and in-home sessions covering topics such as healthy eating and navigating health care. Outcomes and Measures: Self-reported and physiological outcomes: symptom–well-being (primary), stress, sleep disturbance, social satisfaction, physical activity, patient activation, blood pressure, and weight. Exit interviews addressed health experiences and intervention impact on participants’ lives. Results: Participants (N = 27) demonstrated clinically significant pretreatment to long-term follow-up benefits in all symptom–well-being dimensions (Cohen’s d ≥ 0.8, p ≤ .004), with additional gains from posttreatment to long-term follow-up (d ≥ 0.4, p ≤ .05). Significant improvements from pre- to posttreatment in systolic blood pressure, stress, and social role and activity satisfaction were maintained at long-term follow-up. No changes were observed in weight, physical activity, or diastolic blood pressure. Participants described the intervention’s sustained positive effect on their wellness. Conclusions and Relevance: A lifestyle intervention led by occupational therapy practitioners and community health workers in a primary care context has potential to achieve long-term health benefits in rural-dwelling, late-midlife Latinos. What This Article Adds: This study reveals that rural, late-midlife Latinos showed long-lasting improvements in psychological and physical health after finishing a program that helped them make healthy lifestyle choices. This finding supports the unique contribution of occupational therapy in primary care settings.

Abstract
BACKGROUND Neuropsychiatric symptoms play an important role in diagnosing and clinical follow-up of cognitive impairment and dementia. OBJECTIVE We investigated the relationship between neuropsychiatric symptoms, cognitive impairment, and dementia in Hispanics. METHODS We included 529 participants (age ≥40 years) from the Maracaibo Aging Study with standardized neuropsychiatric assessments, including the Neuropsychiatric Inventory (NPI). Based on the Clinical Dementia Rating and the Mini-Mental State Examination scores, participants' cognitive status was categorized into normal cognition, mild/moderate, and severe cognitive impairment. Diagnosis of dementia was established in a consensus conference. Statistical analyses included multivariable logistic regression models and area under the curve (AUC). RESULTS The mean age of participants was 59.3 years, and 71.8%were women. The proportion of dementia was 6.8%. Disturbed sleep, anxiety, and depression were the most common neuropsychiatric symptoms in the study sample. In crude analyses, the proportions of hallucinations, aberrant motor behavior, agitation/aggression, apathy, delusions, irritability, eating disturbance, depression, and euphoria were differently distributed among cognitive status groups (p < 0.05). After accounting for confounders, aberrant motor behavior and agitation/aggression remained significantly associated with cognitive impairment and dementia (p < 0.05). The inclusion of the NPI domains significantly improved the AUC to discriminate severe cognitive impairment and dementia compared to a basic model that included sex, age, education, alcohol, obesity, serum glucose, total cholesterol, hypertension, and stroke. CONCLUSION Neuropsychiatric symptoms are associated with severe cognitive impairment and dementia. The addition of NPI items to the global cognitive assessment might help early detection of dementia in primary care settings.

BMC Geriatr 2020; 20:482.

Abstract
BACKGROUND Numerous studies have documented racial and ethnic differences in the prevalence and incidence of Alzheimer's disease and related dementias (ADRD). Less is known, however, about racial and ethnic differences in health care expenditures among older adults at risk for ADRD (cognitive deficits without ADRD) or with ADRD. In particular, there is limited evidence that racial and ethnic differences in health care expenditures change over the trajectory of ADRD or differ by types of service. METHODS We examined racial and ethnic patterns and differences in health care expenditures (total health care expenditures, out-of-pocket expenditures, and six service-specific expenditures) among Medicare beneficiaries without cognitive deficits, those with cognitive deficits without ADRD, and those with ADRD. Using the 1996-2017 Medical Expenditure Panel Survey, we performed multivariable regression models to estimate expenditure differences among racial and ethnic groups without cognitive deficits, those with cognitive deficits without ADRD, and those with ADRD. Models accounted for survey weights and adjusted for various demographic, socioeconomic, and health characteristics. RESULTS Black, Asians, and Latinos without cognitive deficits had lower total health care expenditures than whites without cognitive deficits ($10,236, $9497, $9597, and $11,541, respectively). There were no racial and ethnic differences in total health care expenditures among those with cognitive deficits without ADRD and those with ADRD. Across all three groups, however, Blacks, Asians, and Latinos consistently had lower out-of-pocket expenditures than whites (except for Asians with cognitive deficits without ADRD). Furthermore, service-specific health care expenditures varied by racial and ethnic groups. CONCLUSIONS Our study did not find significant racial and ethnic differences in total health care expenditures among Medicare beneficiaries with cognitive deficits and/or ADRD. However, we documented significant differences in out-of-pocket expenditures and service-specific expenditures. We speculated that the differences may be attributable to racial and ethnic differences in access to care and/or preferences based on family structure and cultural/economic factors. Particularly, heterogeneous patterns of service-specific expenditures by racial and ethnic groups underscore the importance of future research in identifying determinants leading to variations in service-specific expenditures among racial and ethnic groups.

Abstract
This forum expands and reframes the lens of dementia caregiving research among diverse racial and ethnic groups to better understand the unique needs, stressors, and strengths of multicultural and racial-ethnic family caregivers in the United States. By providing more diverse and inclusive knowledge on caregiving to older adults in the United States, we can create a new path forward with regards to caregiving research. Throughout the article, major questions and answers are supported by critiquing some of the caregiving literature. Discussions are provided to help create inclusive ways of conceptualizing caregiving research and using methodological approaches to reflect the diversity of caregivers and care recipients in the United States. Expanding and reframing the conceptual and methodological lens of diversity, inclusivity and intersectionality can provide evidence to support effective policy, practice, and care in addressing the needs of diverse groups of caregivers and older adults living with dementia.

Abstract
The population of older adults is growing dramatically worldwide. As older adults are at greater risk of developing disorders associated with cognitive dysfunction (i.e., dementia), healthcare costs are expected to double by 2040. Evidence suggests dementia may be slowed or prevented by lifestyle interventions, including physical activity (PA). PA is associated with improved cognitive function and may reduce risk for dementia by mitigating known risk factors (i.e., cardiovascular diseases) and/or by enhancing neurochemical processes. An emerging area of research suggests the gut microbiome may have similar neuroprotective effects. Altering the gut microbiome has been found to target physiological processes associated with dementia risk, and it influences gut-brain-microbiome axis signaling, impacting cognitive functioning. The gut microbiome can be altered by several means (i.e., disease, diet, prebiotics, probiotics), including PA. As PA and the gut microbiome independently influence cognitive function and PA changes the composition of the gut microbiome, cognitive improvement due to PA may be partially mediated by the gut microbiome. The present article provides an overview of the literature regarding the complex associations among PA, cognitive function, and the gut microbiome, as well as their underlying biological mechanisms. A comprehensive, theoretical model integrating evidence for the potential mediation is proposed.

Family Functionality, cognitive status and social participation are related to survival in nonagenarians and centenarians: data from a Brazilian cohort study. PAJAR - PAN AMERICAN JOURNAL OF AGING RESEARCH 2020. [DOI: 10.15448/2357-9641.2020.1.35893] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/08/2022] Open
Abstract
Aim: To evaluate whether family functionality, using the instrument “Adaptation, Partnership, Growth, Affection, and Resolve” (APGAR) and its components, as well as other health indicators, influences the survival of nonagenarians and centenarians.
Methods: Participants were randomly identified and evaluated in their homes of Porto Alegre — Brazil. Death or survival information were verified by telephone or death registry system. Follow-up time measured the number of months between the first evaluation and the date of death or the last contact. Participants with APGAR ≥ 7 were classified with good functionality. The APGAR components were analyzed as yes or no.
Results: Two-hundred-fourteen participants (73% women, age 92.4±3.59 years) were followed during 23±10.0 months. Sixty-on (28.5%) died. Survivors were younger (p<0.001), had better cognitive performance (p<0.001), and reported more frequently leaving home (p=0.010) and participating in social activities (p<0.001). Survivors had a similar frequency for good family functioning (90% p=0.994), but more often they were satisfied with their family time (p=0.032) and with the way the family showed affection and reacted to their feelings (p=0.083).
Conclusions: Family affection and time were significantly associated with lower hazard-ratio, even adjusted for age, as well as cognitive performance, social activities and the habit of leaving home. In addition to the preservation of cognitive performance, to remain physically and socially active, family support is related to the higher survival rate in nonagenarians and centenarians in Brazil.

Abstract
This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on caregivers and society. The Special Report discusses the future challenges of meeting care demands for the growing number of people living with Alzheimer's dementia in the United States with a particular emphasis on primary care. By mid-century, the number of Americans age 65 and older with Alzheimer's dementia may grow to 13.8 million. This represents a steep increase from the estimated 5.8 million Americans age 65 and older who have Alzheimer's dementia today. Official death certificates recorded 122,019 deaths from AD in 2018, the latest year for which data are available, making Alzheimer's the sixth leading cause of death in the United States and the fifth leading cause of death among Americans age 65 and older. Between 2000 and 2018, deaths resulting from stroke, HIV and heart disease decreased, whereas reported deaths from Alzheimer's increased 146.2%. In 2019, more than 16 million family members and other unpaid caregivers provided an estimated 18.6 billion hours of care to people with Alzheimer's or other dementias. This care is valued at nearly $244 billion, but its costs extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are more than three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 23 times as great. Total payments in 2020 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $305 billion. As the population of Americans living with Alzheimer's dementia increases, the burden of caring for that population also increases. These challenges are exacerbated by a shortage of dementia care specialists, which places an increasing burden on primary care physicians (PCPs) to provide care for people living with dementia. Many PCPs feel underprepared and inadequately trained to handle dementia care responsibilities effectively. This report includes recommendations for maximizing quality care in the face of the shortage of specialists and training challenges in primary care.

Abstract
Background: In-Home Supportive Services (IHSS) cares for millions of Medicaid-eligible older adults who are often homebound and socially isolated. Advance care planning (ACP) can be challenging for this population, and IHSS programs may play an important role. Objective: To explore the feasibility of an IHSS ACP program for frail older adults. Design: Semistructured focus groups. Setting/Subjects: Fifty IHSS stakeholders (20 administrators, 9 case managers, 13 in-home caregivers, and 8 clients) participated in 10 focus groups in San Francisco. Measurements: Qualitative thematic content analysis by two independent coders. Results: Four main themes emerged: (1) Unmet needs: patients' wishes unknown during a medical crisis, lack of education/training for clients and staff; (2) Barriers: conflict of interest and potential medical overreach of IHSS caregivers, lack of billing avenues, time limitations, and cultural, literacy, and language barriers; (3) Facilitators: leveraging established workflows, available technology, and training programs; and (4) Implementation: use a tailored, optional approach based on clients' readiness, focus on case managers not caregivers to prevent conflict of interest; use established intake, follow-up, and training procedures; consider cultural and literacy-appropriate messaging; and standardize easy-to-use procedures, simple scripts, and educational guides, within established workflow to support case managers. Conclusions: An IHSS ACP program is important and feasible for Medicaid-eligible, frail older adults. Implementation suggestions for success by IHSS stakeholders include focusing on case managers rather than in-home caregivers to prevent conflict of interest; tailoring programs to clients' readiness, literacy, and language; creating educational programs for IHSS staff, clients, and community; and standardizing easy-to-use guides and procedures into IHSS workflows.

Abstract
OBJECTIVE The purpose of this study was to evaluate the measurement invariance of a neuropsychological battery across race/ethnicity by sex/gender subgroups over repeated measurements. METHOD Participants were 6,057 non-Hispanic White (NHW), Black, and Hispanic men and women in the Washington/Hamilton Heights Inwood Columbia Aging Project (WHICAP) who were administered neuropsychological tests of memory, language, and visuospatial abilities at 18 to 24-month intervals for up to 25 years. Invariance analyses were conducted on the three-factor model across sex/gender, racial/ethnic, and sex/gender by racial/ethnic subgroups, as well as across five assessment timepoints. RESULTS The three-factor model demonstrated full measurement invariance across sex/gender groups and over repeated measurements. However, partial measurement invariance (invariant factor structure and factor loadings but nonequivalent observed score intercepts) for the language domain was exhibited across racial/ethnic and sex/gender by racial/ethnic subgroups. CONCLUSION Establishing measurement invariance is essential for valid interpretation of group differences in cognitive test performance. Findings from the current study highlight the need for continued examination of sex/gender by racial/ethnic differences in measurement properties of assessment tools, as well as expanded research on sex/gender variability across other understudied racial/ethnic groups.

Abstract
Dementia is the fastest growing epidemic in the developed nations, and if not curtailed, it will single handedly collapse our health care system. The prevalence of dementia is 1 in 10 individuals older than 65 years and increases to 50% of all individuals older than 85 years. The prevalence of Alzheimer's dementia (AD), the most common form of dementia, has been increasing rapidly and is projected to reach 16 million individuals by the year 2050. Several prevailing myths about the science of dementia are discussed, such as that AD is inevitable and that it is exclusively a genetic disease. The fact is that AD is dependent on a multitude of genetic, epigenetic, and environmental factors that interact with one another. In fact, 4 core drivers represent 90% of what determines disease progression in AD. These are (1) glucose or energy dysregulation, (2) lipid dysregulation, (3) inflammation, and (4) oxidation. Lifestyle change can significantly alter the course of AD. The authors have created an acronym-NEURO-to help lifestyle practitioners and the public remember the most important lifestyle elements in the treatment and prevention of AD based on the evidence. "N" is for Nutrition, "E" for Exercise, "U" for Unwind (stress management), "R" for Restorative Sleep, and "O" for Optimizing mental and social activity. The evidence base for each of the components is reviewed.

Abstract
INTRODUCTION Alzheimer's disease and related dementias (ADRD) cause a high burden of morbidity and mortality in the United States. Age, race, and ethnicity are important risk factors for ADRD. METHODS We estimated the future US burden of ADRD by age, sex, and race and ethnicity by applying subgroup-specific prevalence among Medicare Fee-for-Service beneficiaries aged ≥65 years in 2014 to subgroup-specific population estimates for 2014 and population projection data from the United States Census Bureau for 2015 to 2060. RESULTS The burden of ADRD in 2014 was an estimated 5.0 million adults aged ≥65 years or 1.6% of the population, and there are significant disparities in ADRD prevalence among population subgroups defined by race and ethnicity. ADRD burden will double to 3.3% by 2060 when 13.9 million Americans are projected to have the disease. DISCUSSION These estimates can be used to guide planning and interventions related to caring for the ADRD population and supporting caregivers.

Abstract
INTRODUCTION The trends in prevalence and incidence of Alzheimer's disease (AD) dementia remain uncertain. METHODS A sample of 2794 participants with a clinical diagnosis for AD dementia were included. RESULTS The 2010 census standardized prevalence of AD dementia was 14.5% (95% CI = 13.7-15.3), and annual incidence was 2.3% (1.7-2.9). Both prevalence and incidence showed substantial variation over time, but no secular trends. The prevalence of AD dementia did not change significantly from 14.6% (95% CI = 13.0, 16.2) in 1994-1997 to 14.7% (95% CI = 13.2, 16.2) in 2010-2012 (P = .84). The annual incidence of AD dementia was 2.8% (95% CI = 2.2, 3.2) in 1998-2000 and 2.2% (95% CI = 1.6, 2.8) in 2004-2006 (P = .20) and remained steady in 2010-2012. The prevalence and incidence among African Americans were approximately twice than those among European Americans. CONCLUSIONS The prevalence and incidence of AD dementia showed substantial variation between 1994 and 2012, but no secular trend.

Associations of Body Mass Index and Waist Circumference with 3-Year All-Cause Mortality Among the Oldest Old: Evidence from a Chinese Community-Based Prospective Cohort Study. J Am Med Dir Assoc 2018; 19:672-678.e4. [PMID: 29807748 PMCID: PMC6934415 DOI: 10.1016/j.jamda.2018.03.015] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2018] [Revised: 03/27/2018] [Accepted: 03/30/2018] [Indexed: 01/10/2023]
Abstract
OBJECTIVE Current international and national guidelines for body mass index (BMI) and waist circumference (WC) have been recommended to all adults. However, whether recommendations applied to the oldest old (aged 80+) is poorly known. The study objective was to investigate the relation of BMI and WC with 3-year all-cause mortality among the oldest old. DESIGN, SETTING, AND PARTICIPANTS A total of 4361 Chinese oldest old (mean age 91.8) participated in this community-based prospective cohort study. MEASUREMENTS BMI and WC were measured at baseline in 2011 and were used as continuous variables and as categorized variables by recommendations or by tertiles. Adjusted, sex-stratified Cox models with penalized splines and Cox models were constructed to explore the association. RESULTS Greater BMI and WC were linearly associated with lower mortality risk in both genders. The mortality risk was the lowest in overweight or obese participants (BMI ≥ 24.0) and was lower in participants with abdominal obesity. Compared to the upper tertile, those in the middle and lower tertile of BMI had a higher risk of mortality for men [hazard ratio (HR): 1.23 (1.02-1.48) and 1.53 (1.28-1.82)] and for women [HR: 1.21 (1.03-1.41) and 1.35 (1.15-1.58)]; it was also found in participants in the middle and lower tertile of WC for men [HR: 1.21 (1.01-1.46) and 1.41 (1.18-1.69)] and for women [HR: 1.35 (1.15-1.58) and 1.55 (1.32-1.81)] (all the P values for trend <.001). These findings were robust in further sensitivity analyses or when using propensity score matching, in subgroup analyses, or in octogenarians, nonagenarians, and centenarians. CONCLUSIONS In Chinese oldest old, both higher BMI and higher WC predict better survival in both genders. The finding suggests optimal BMI and WC may be sensitive to age, thus, the current recommendations for the oldest old may need to be revisited.

Abstract
INTRODUCTION Older Mexican Americans are living longer with multiple chronic conditions (MCCs). This has placed greater demands on caregivers to assist with basic activities of daily living (ADL) or instrumental activities of daily living (IADL). To understand the needs of older Mexican-American care recipients, we examined the impact of MCC on ADL and IADL limitations. METHODS We analyzed data from 485 Mexican American care-receiving/caregiving dyads. Selected MCCs in the analysis were diabetes, hypertension, stroke, heart disease, arthritis, emphysema/chronic obstructive pulmonary disease, cognitive impairment, depression, and cancer. Care recipients were dichotomized as having 3 or more conditions or as having 2 or fewer conditions. Three comorbidity clusters were established on the basis of the most prevalent health conditions among participants with comorbid arthritis and hypertension. These clusters included arthritis and hypertension plus: diabetes (cluster 1), cognitive impairment (cluster 2), and heart disease (cluster 3). RESULTS Care recipients with 3 or more chronic conditions (n = 314) had higher odds of having mobility limitations (OR = 1.98; 95% CI, 1.34-2.94), self-care limitations (OR = 2.53; 95% CI, 1.70-3.81), >3 ADL limitations (OR = 2.00; 95% CI, 1.28-3.17), and >3 IADL limitations (OR = 1.88; 95% CI, 1.26-2.81). All clusters had increased odds of ADL and severe ADL limitations. Of care recipients in cluster 2, those with arthritis, hypertension, and cognitive impairment had significantly higher odds of mobility limitations (OR = 2.33; 95% CI, 1.05-5.24) than those with just arthritis and hypertension. CONCLUSION MCCs were associated with more ADL and IADL limitations among care recipients, especially for those with hypertension and arthritis plus diabetes, cognitive impairment, or heart disease. These findings can assist in developing programs to meet the needs of older Mexican-American care recipients.

Abstract
Objective: This article examines differences in nursing home use and quality among Medicare beneficiaries, in both Medicare Advantage and fee-for-service, newly admitted to nursing homes with Alzheimer's disease and related dementias (ADRD). Method: Retrospective, national, population-based study of Medicare residents newly admitted to nursing homes with ADRD by race and ethnic group. Our analytic sample included 1,302,099 nursing home residents-268,181 with a diagnosis of ADRD-in 13,532 nursing homes from 2014. Results: We found that a larger share of Hispanic Medicare residents that are admitted to nursing homes have ADRD compared with African American and White beneficiaries. Both Hispanics and African Americans with ADRD received care in segregated nursing homes with fewer resources and lower quality of care compared with White residents. Discussion: These results have implications for targeted efforts to achieve health care equity and quality improvement efforts among nursing homes that serve minority patients.

Abstract
OBJECTIVE In this article, we examine the demographics of living arrangements and household headship status among Mexican-origin individuals aged 85+ years. METHOD Data come from the Hispanic Established Populations for the Epidemiologic Study of the Elderly (H-EPESE) caregiver and respondent surveys. RESULTS Finances of the elderly individual and their caregiver inform living arrangement decisions. Physical and cognitive disability differentiate among living arrangements: The most mentally and physically impaired are most likely to live with others and less likely to be the head of the household. DISCUSSION Motivations for living with others are clearly more complex than simple filial piety considerations might hold. Extended living arrangements provide concrete financial and instrumental benefits for both elderly parents and their adult child caregiver. Future research should address the question of the capacity of the Mexican American family to provide care for elderly parents in the face of major demographic and social changes.

Abstract
It is commonly believed that older adults are often ill and therefore high users of health services. A pilot study involving adults 60 and older living in the Canadian province of Alberta was conducted to (a) raise interest in the concepts of lifelong health and health services use; (b) develop a lifelong health data collection tool; (c) obtain information about lifelong and recent health services use, and self-perceived lifelong and current health; and (d) reveal links (if any) between perceived health and lifelong health services use. A questionnaire was developed, pilot tested, and posted for completion by 100 volunteers. Most older adults reported good or very good current and lifelong health. Comorbidities and low finances were associated with higher health services use. These findings suggest community-dwelling older adults may be healthy currently and throughout their lives. Gerontological nursing research, practice, and advocacy are needed because myths about aging must be addressed to refocus attention on the importance of lifelong health promotion for older adults.

Abstract
This report describes the public health impact of Alzheimer's disease, including incidence and prevalence, mortality rates, costs of care, and the overall impact on caregivers and society. It also examines in detail the financial impact of Alzheimer's on families, including annual costs to families and the difficult decisions families must often make to pay those costs. An estimated 5.4 million Americans have Alzheimer's disease. By mid-century, the number of people living with Alzheimer's disease in the United States is projected to grow to 13.8 million, fueled in large part by the aging baby boom generation. Today, someone in the country develops Alzheimer's disease every 66 seconds. By 2050, one new case of Alzheimer's is expected to develop every 33 seconds, resulting in nearly 1 million new cases per year. In 2013, official death certificates recorded 84,767 deaths from Alzheimer's disease, making it the sixth leading cause of death in the United States and the fifth leading cause of death in Americans age ≥ 65 years. Between 2000 and 2013, deaths resulting from stroke, heart disease, and prostate cancer decreased 23%, 14%, and 11%, respectively, whereas deaths from Alzheimer's disease increased 71%. The actual number of deaths to which Alzheimer's disease contributes is likely much larger than the number of deaths from Alzheimer's disease recorded on death certificates. In 2016, an estimated 700,000 Americans age ≥ 65 years will die with Alzheimer's disease, and many of them will die because of the complications caused by Alzheimer's disease. In 2015, more than 15 million family members and other unpaid caregivers provided an estimated 18.1 billion hours of care to people with Alzheimer's and other dementias, a contribution valued at more than $221 billion. Average per-person Medicare payments for services to beneficiaries age ≥ 65 years with Alzheimer's disease and other dementias are more than two and a half times as great as payments for all beneficiaries without these conditions, and Medicaid payments are 19 times as great. Total payments in 2016 for health care, long-term care and hospice services for people age ≥ 65 years with dementia are estimated to be $236 billion. The costs of Alzheimer's care may place a substantial financial burden on families, who often have to take money out of their retirement savings, cut back on buying food, and reduce their own trips to the doctor. In addition, many family members incorrectly believe that Medicare pays for nursing home care and other types of long-term care. Such findings highlight the need for solutions to prevent dementia-related costs from jeopardizing the health and financial security of the families of people with Alzheimer's and other dementias.

Abstract
This cross-sectional study was completed to characterize the health status, perceptions and needs of Hispanics in Shelbyville, KY, USA. Community Health Workers interviewed 668 Hispanic residents in Shelbyville, KY, USA. Data were collected from 2009 to 2010 and analyzed from 2011 until present. Hispanic immigrants from Mexico and other Central American countries completed the survey. The most common self-reported diseases were allergies, asthma, diabetes, lung disease and cardiovascular disease. High blood pressure and diabetes were the two most common diagnoses among insured, older females. Health education, disease prevention and nutrition were the top health concerns among participants. Deficits in health care infrastructure for this largely transient community may compromise their ability to meet health care needs and concerns. Similar issues may be faced by other disadvantaged Hispanic communities in the continental US and likely to be influenced by anticipated provisions of the Patient Protection and Affordable Care Act.

Abstract
INTRODUCTION Advance care planning (ACP) is a process that allows patients to identify their goals for medical care. Traditionally, ACP has focused on completing advance directives; however, we have expanded the ACP paradigm to also prepare patients to communicate their wishes and make informed decisions. To this end, we created an ACP website called PREPARE (http://www.prepareforyourcare.org) to prepare diverse English-speaking and Spanish-speaking older adults for medical decision-making. Here, we describe the study protocol for a randomised controlled efficacy trial of PREPARE in a safety-net setting. The goal is to determine the efficacy of PREPARE to engage diverse English-speaking and Spanish-speaking older adults in a full spectrum of ACP behaviours. METHODS AND ANALYSIS We include English-speaking and Spanish-speaking adults from an urban public hospital who are ≥55 years old, have ≥2 chronic medical conditions and have seen a primary care physician ≥2 times in the last year. Participants are randomised to the PREPARE intervention (review PREPARE and an easy-to-read advance directive) or the control arm (only the easy-to-read advance directive). The primary outcome is documentation of an advance directive and/or ACP discussion. Secondary outcomes include ACP behaviour change processes measured with validated surveys (eg, self-efficacy, readiness) and a broad range of ACP actions (eg, choosing a surrogate, identifying goals for care, discussing ACP with clinicians and/or surrogates). Using blinded outcome ascertainment, outcomes will be measured at 1 week and at 3, 6 and 12 months, and compared between study arms using mixed-effects logistic regression and mixed-effects linear, Poisson or negative binomial regression. ETHICS AND DISSEMINATION This study has been approved by the appropriate Institutional Review Boards and is guided by input from patient and clinical advisory boards and a data safety monitoring board. The results of this study will be disseminated to academic and community stakeholders. TRIAL REGISTRATION NUMBERS NCT01990235; NCT02072941; Pre-results.
