Abstract
Objectives
Exposure to stressors is differentially distributed by race/ethnicity with minority groups reporting a higher stress burden than their white counterparts. However, to really ...understand the extent to which some groups bear a disproportionate stress burden, we need to consider race/ethnic differences in stress appraisal, specifically how upsetting stressors may be, in addition to stress exposure. We examine racial/ethnic differences in both the number of reported chronic stressors across five domains (health, financial, residential, relationship, and caregiving) and their appraised stressfulness among a diverse sample of older adults.
Method
Data come from 6,567 adults ages 52+ from the 2006 Health and Retirement Study.
Results
Results show older blacks, U.S. and foreign-born Hispanics report more chronic stress exposure than whites and are two to three times as likely to experience financial strain and housing-related stress. Socioeconomic factors fully explain the Hispanic–white difference in stress exposure, but black–white differences remain. Despite experiencing a greater number of stressors, blacks and U.S.-born Hispanics are less likely to be upset by exposure to stressors than whites. U.S.-born Hispanics are less upset by relationship-based stressors specifically, while blacks are less upset across all stress domains in fully-adjusted models. Foreign-born Hispanics are only less upset by caregiving strain.
Discussion
The distinction between exposure and appraisal-based measures of stress may shed light on important pathways that differentially contribute to race/ethnic physical and mental health disparities.
T cells clear virus from the CNS and dynamically regulate brain functions, including spatial learning, through cytokine signaling. Here we determined whether hippocampal T cells that persist after ...recovery from infection with West Nile virus (WNV) or Zika virus (ZIKV) impact hippocampal-dependent learning and memory. Using newly established models of viral encephalitis recovery in adult animals, we show that in mice that have recovered from WNV or ZIKV infection, T cell-derived interferon-γ (IFN-γ) signaling in microglia underlies spatial-learning defects via virus-target-specific mechanisms. Following recovery from WNV infection, mice showed presynaptic termini elimination with lack of repair, while for ZIKV, mice showed extensive neuronal apoptosis with loss of postsynaptic termini. Accordingly, animals deficient in CD8
T cells or IFN-γ signaling in microglia demonstrated protection against synapse elimination following WNV infection and decreased neuronal apoptosis with synapse recovery following ZIKV infection. Thus, T cell signaling to microglia drives post-infectious cognitive sequelae that are associated with emerging neurotropic flaviviruses.
...the rapid increases in the diverse aging population suggest that there is an urgent need to understand the risks that immigration, nativity status, and racial stratification impose that influence ...late-life cognition, including the physiological and psychological mechanisms that play a critical role in health across the lifespan and generations. Mohammad et al.’s (2020) study demonstrates that respondents with “distributed education” exhibited higher scores in episodic memory and name recognition measures, suggesting that a respondent’s prolonged exposure to being involved in the learning process across the lifespan results in improved cognitive reserve. ...continuing education among foreign-born older adults in the USA may be an effective public health policy intervention to delay or slow cognitive decline, in addition to intervention strategies tailored based on education level and are culturally appropriate as highlighted recently by other researchers in International Psychogeriatrics (Radanovic, 2020; Yuan et al., 2018). The findings from using the KHANDLE can provide vital information for research and clinical applications of cognitive tests, identifying individuals at higher risk for cognitive impairment and improving the health and well-being of individuals using culturally relevant and appropriate measures. Notably, the KHANDLE included participants with long-term access to integrated health care (i.e. usual care), which is not the norm for the general population, especially racial and ethnic minorities across the USA. ...many populations disproportionately rely on acute illness care to meet basic and primary care needs, suggesting a missed opportunity for ADRD research recruitment efforts (Gilmore-Bykovskyi et al., 2019).
Lifetime exposure to interpersonal violence or abuse has been associated with several chronic diseases, including adult-onset diabetes, yet this pattern has not been confirmed by sex and race within ...a large cohort.
Data from the Southern Community Cohort Study collected between 2002–2009 and 2012–2015 were used to explore the relationship between lifetime interpersonal violence or abuse and diabetes (N=25,251). Prospective analyses of lower-income people living in the southeastern U.S. were conducted in 2022 to examine the risk of adult-onset diabetes associated with lifetime interpersonal violence or abuse by sex and race. Lifetime interpersonal violence or abuse was defined as (1) physical or psychological violence, threats, or abuse in adulthood (adult interpersonal violence or abuse) and (2) childhood abuse or neglect.
After adjustment for potentially confounding factors, adult interpersonal violence or abuse was associated with a 23% increased risk of diabetes (adjusted hazard ratio=1.23; 95% CI=1.16, 1.30). Diabetes risks associated with childhood abuse or neglect were 15% (95% CI=1.02, 1.30) for neglect and 26% (95% CI=1.19, 1.35) for abuse. When combining adult interpersonal violence or abuse and childhood abuse or neglect, the risk of diabetes was 35% higher (adjusted hazard ratio=1.35; 95% CI=1.26, 1.45) than those experiencing no violence, abuse, or neglect. This pattern held among Black and White participants, and among women and men.
Both adult interpersonal violence or abuse and childhood abuse or neglect increased the risk of adult-onset diabetes in a dose-dependent pattern for men and women, and by race. Intervention and prevention efforts to reduce adult interpersonal violence or abuse and childhood abuse or neglect could not only reduce the risk of lifetime interpersonal violence or abuse but may also reduce one of the most prevalent chronic diseases, adult-onset diabetes.
In the United States (U.S.), more than 12 million women reported illicit drug use in the past month. Drug use has been linked to increased risk for HIV, but little is known about the uptake of HIV ...pre-exposure prophylaxis (PrEP) to prevent HIV among women who use drugs (WWUD). Following the PRISMA guideline, we conducted a multi-database literature search to assess engagement along the PrEP care continuum among WWUD in the U.S. Seven studies with a total of 755 women were included in the review: 370 (49%) Black, 126 (16.7%) Hispanics, and 259 (34.3%) Whites. Employing random-effect models, data indicate 20.6% (95% CI 8.7%, 32.4%) of WWUD were aware of PrEP, and 60.2% (95% CI 52.2%, 68.2%) of those aware were also willing to use PrEP. Notwithstanding study limitations, our findings suggest there may be potential to increase PrEP uptake among WWUD, but efforts must first concentrate on improving PrEP awareness among this population.
Telomere length (TL) has been suggested as a biomarker that can indicate individual variability in the rate of aging. Yet, it remains unclear whether TL is related to recognized indicators of health ...in an aging, older nationally representative sample. We examine whether TL is associated with 15 biological, physical, and cognitive markers of health among older adults ages 54+. TL was assayed from saliva using quantitative polymerase chain reaction (T/S ratio) in the 2008 Health and Retirement Study (n = 4,074). We estimated probability of high-risk levels across indictors of health by TL and age-singly and jointly. TL was associated with seven indicators of poor functioning: high-density lipoprotein and total cholesterol, cystatin C, pulse pressure, body mass index, lung function, and walking speed. However, after adjusting for age, associations were substantially attenuated; only associations with cholesterol and lung function remained significant. Additionally, findings show TL did not add to the predictive power of chronological age in predicting poor functioning. While TL may not be a useful clinical marker of functional aging in an older adult population, it may still play an important role in longitudinal studies in young and middle aged populations that attempt to understand aging.
The authors sought to determine the impact of selected social determinants of health (SDoH) on psychological health and well-being (defined as depression, cognition, and self-rated health) among ...Black and Hispanic/Latinx adults relative to White adults 51-89 years of age.
Disparities in depressive symptomatology, cognition, and self-rated health were measured among 2,306 non-Hispanic/Latinx Black, 1,593 Hispanic/Latinx, and 7,244 non-Hispanic/Latinx White adults who participated in the Health and Retirement Study (N=11,143). Blinder-Oaxaca decomposition was used to examine whether differences in selected SDoH explained a larger share of the disparities than age, sex, measures of health, health behaviors, and health care utilization. Selected SDoH included education, parental education, number of years worked, marital status, veteran status, geographic residence, nativity status, income, and insurance coverage.
Black and Hispanic/Latinx adults reported worse depressive symptomatology, cognition, and self-rated health than White adults. Selected SDoH were associated with a larger proportion of the Black-White disparities in depressive symptomatology (51%), cognition (39%), and self-rated health (37%) than were age, sex, measures of health, health behaviors, and health care utilization. SDoH were associated with a larger proportion of the Hispanic/Latinx-White disparity in cognition (76%) and self-rated health (75%), but age and physical health correlated with the disparity in depressive symptomatology (28%). Education, parental education, years worked, income, and insurance parity were SDoH associated with these disparities.
Differences in SDoH underlie racial/ethnic disparities in depression, cognition, and self-rated health among older adults. Education, income, number of years worked, and insurance parity are key SDoH.
The effect of years of education on the maintenance of healthy cognitive functioning may differ by race and ethnicity given historical and ongoing inequities in educational quality.
We examined ...20,311 Black, Latinx, and White adults aged 51-100 from the Health and Retirement Study (2008-2016). Telephone Interview for Cognitive Status-27 data was used to measure cognitive functioning. Generalized additive mixed models were stratified by race and ethnicity and educational attainment (≥12 vs. <12 years). Selected social determinants of health, all-cause mortality, time-varying health and healthcare utilization characteristics, and study wave were included as covariates.
On average, Black and Latinx adults scored lower at baseline compared to White adults regardless of educational attainment (p < 0.001), with a significant overlap in the distributions of scores. The rate of cognitive decline was non-linear for Black, Latinx, and White adults (p < 0.001), and a period of stability was witnessed for those with higher educational attainment irrespective of race and ethnicity. Compared to Black, Latinx, and White adults with lower educational attainment, higher-educated White adults received the greatest protection from cognitive decline (13 years; 64 vs. 51), followed by Latinx (12 years; 67 vs. 55), and Black adults (10 years; 61 vs. 51). Latinx adults experienced cognitive decline beginning at a later age.
The extent to which higher educational attainment protects adults from cognitive decline differs by race and ethnicity, such that higher-educated White adults received a greater benefit than higher-educated Black or Latinx adults.
Although HIV and substance use disorders (SUDs) constitute a health syndemic, no research to date has examined the perceived negative impacts of different SUDs for people with HIV (PWH). In May 2019, ...643 stakeholders in the U.S., representing clients of AIDS service organizations (ASOs), ASO staff, and HIV/AIDS Planning Council members, participated in an innovative Stakeholder-Engaged Real-Time Delphi (SE-RTD) survey focused on the prevalence and individual-level negative impact of five SUDs for PWH. The SE-RTD method has advantages over conventional survey methods by efficiently sharing information, thereby reducing the likelihood that between-group differences are simply due to lack of information, knowledge, and/or understanding. The population-level negative impacts were calculated by weighting each SUD’s individual-level negative impact on indicators of the HIV Care Continuum and other important areas of life by the perceived prevalence of each SUD. Overall, we found these SUDs to have the greatest population-level negative impact scores (possible range 0–24): alcohol use disorder (population-level negative impact = 6.9; perceived prevalence = 41.9%), methamphetamine use disorder (population-level negative impact = 6.5; perceived prevalence = 3.2%), and opioid use disorder (population-level negative impact = 6.4; perceived prevalence = 34.6%). Beyond further demonstration of the need to better integrate SUD services within HIV settings, our findings may help inform how finite funding is allocated for addressing the HIV-SUD syndemic within the U.S. Based on our findings, such future efforts should prioritize the integration of evidence-based treatments that help address use disorders for alcohol, methamphetamine, and opioids.
