Background and Objectives: Little is known about how race/ethnicity and geographic context relate to support service use among dementia caregivers. Our objectives were to investigate (a) whether the use of at least one formal caregiving service-support groups, respite care, and training-differed by race/ethnicity and across metro and nonmetro areas; and (b) whether predisposing, enabling, and need characteristics influenced support service use by race/ethnicity., Research Design and Methods: Data were analyzed from a sample of primary caregivers of care recipients aged 65 years or older with probable dementia (n = 482) in the 2017 National Health and Aging Trends Study and National Study of Caregiving. We calculated weighted prevalence estimates and then used the Hosmer-Lemeshow goodness of fit statistic to find the best-fitting logistic regression models., Results: Among minority dementia caregivers, support service use was higher in metro than nonmetro areas (35% and 15%); the trend was reversed for non-Hispanic White caregivers (47% nonmetro and 29% metro). The best-fitting regression models included predisposing, enabling, and need factors for both minority and non-Hispanic White caregivers. Younger age and more disagreement within the family were consistently associated with more service use in both groups. Among minority caregivers, better caregiver and care recipient health were associated with using support services. Among non-Hispanic White caregivers, nonmetro geographic context and caregiving interfering with valued activities were associated with using support services., Discussion and Implications: Geographic context differently affected support service use and the influence of predisposing, enabling, and need factors varied by race/ethnicity., (© The Author(s) 2023.

Objectives: Few studies have examined how the intersectionality of geographic context and race/ethnicity influences dementia caregiving. Our objectives were to determine whether caregiver experiences and health (a) differed across metro and nonmetro areas and (b) differed by caregiver race/ethnicity and geography., Methods: We used data from the 2017 National Health and Aging Trends Study and National Study of Caregiving. The sample included caregivers (n = 808) of care recipients ages 65 and older with "probable" dementia (n = 482). The geographic context was defined as the care recipient's residence in metro or nonmetro counties. Outcomes included caregiving experiences (care situation, burden, and gains) and health (self-rated anxiety, depression symptoms, and chronic health conditions)., Results: Bivariate analyses indicated that nonmetro dementia caregivers were less racially/ethnically diverse (82.7% White, non-Hispanic) and more were spouses/partners (20.2%) than their metro counterparts (66.6% White, non-Hispanic; 13.3% spouses/partners). Among racial/ethnic minority dementia caregivers, nonmetro context was associated with more chronic conditions (p < .01), providing less care (p < .01), and not coresiding with care recipients (p < .001). Multivariate analyses demonstrated that nonmetro minority dementia caregivers had 3.11 times higher odds (95% confidence interval [CI] = 1.11-9.00) of reporting anxiety in comparison to metro minority dementia caregivers., Discussion: Geographic context shapes dementia caregiving experiences and caregiver health differently across racial/ethnic groups. Findings are consistent with previous studies that have shown that feelings of uncertainty, helplessness, guilt, and distress are more prevalent among people providing caregiving from a distance. Despite higher rates of dementia and dementia-related mortality in nonmetro areas, findings suggest both positive and negative aspects of caregiving among White and racial/ethnic minority caregivers., (© The Author(s) 2022.

We sought to determine whether the biomarkers of chronic inflammation predict cognitive decline in a prospective observational study. We measured baseline serum soluble urokinase plasminogen activator receptor (suPAR) and high sensitivity C‐reactive protein (hs‐CRP) levels in 282 participants of the University of Michigan Memory and Aging Project. Cognitive function was measured using the Montreal Cognitive Assessment (MoCA) and the Clinical Dementia Rating (CDR) scale for up to five time points. SuPAR and hs‐CRP levels were not significantly higher in participants with mild cognitive impairment (n = 97) or dementia (n = 59), compared to those with normal cognitive function (n = 126). Overall, 14% of participants experienced significant cognitive decline over the study period. The change in MoCA or CDR scores over time did not differ significantly according to baseline suPAR or hs‐CRP levels. Chronic systemic inflammation, as measured by serum suPAR or hs‐CRP levels, is unlikely to contribute significantly to cognitive decline. [ABSTRACT FROM AUTHOR]

An introduction is presented in which the author discusses articles within the issue on topics including the role of cultural complexity in Alzheimer's disease and related dementias (ADRD) care, incidence and prevalence of ADRD in minoritized racial and ethnic groups, and factors that influence ADRD care.

Caregiving research has not accounted for increasingly diverse and complex marital and family histories of older Americans. The authors examined social relations and care-specific positive and negative support networks among late-life remarried wife dementia caregivers (N = 61) to determine associations among network structure, relationship quality with and support received from network members, and global assessments of family and stepfamily disagreement on caregiver well-being. Own family and friends predominated in the social relations and positive networks. Although over half (54%) of respondents included a stepfamily member in their positive networks, stepchildren comprised the largest group (35%) in the negative networks. Larger negative networks and actively negative interactions were related to greater caregiver burden, and more global disagreement with stepfamily was associated with greater depression and burden. The findings illustrate the complex nature of support and the value of targeted examinations of caregiving support dynamics among late-life remarried older adults and stepfamilies facing health demands.

To compare rural–urban health care costs among Latinx adults ages 51+ and examine variations by dementia status.Data are from the Health and Retirement Study (2006–2018 waves; n = 15,567). We inflation-adjusted all health care costs using the 2021 consumer price index. Geographic context and dementia status were the main exposure variables. We applied multivariate two-part generalized linear models and adjusted for sociodemographic and health characteristics.Rural residents had higher total health care costs, regardless of dementia status. Total health care costs were $850 higher in rural ($2,640) compared to urban ($1,789) areas (p < .001). Out-of-pocket costs were $870 higher in rural ($2,677) compared to urban ($1,806) areas (p < .001). Dementia status was not an effect modifier.Health care costs are disproportionately higher among Latinx rural, relative to urban, residents. Addressing health care costs among Latinx rural residents is a public health priority. [ABSTRACT FROM AUTHOR]
