RESUMEN
PURPOSE: Disparities in breast cancer survival remain a challenge. We aimed to analyze the effect of structural racism, as measured by the Index of Concentration at the Extremes (ICE), on receipt of National Cancer Center Network (NCCN) guideline-concordant breast cancer treatment. METHODS: We identified patients treated at two institutions from 2005 to 2017 with stage I-IV breast cancer. Census tracts served as neighborhood proxies. Using 5-year estimates from the American Community Survey, 5 ICE variables were computed to create 5 models, controlling for economic segregation, non-Hispanic Black (NHB) segregation, NHB/economic segregation, Hispanic segregation, and Hispanic/economic segregation. Multi-level logistic regression models were used to determine the association between individual and neighborhood-level characteristics on receipt of NCCN guideline-concordant breast cancer treatment. RESULTS: 5173 patients were included: 55.2% were Hispanic, 27.5% were NHW, and 17.3% were NHB. Regardless of economic or residential segregation, a NHB patient was less likely to receive appropriate treatment [(OR)Model1 0.58 (0.45-0.74); ORModel2 0.59 (0.46-0.78); ORModel3 0.62 (0.47-0.81); ORModel4 0.53 (0.40-0.69); ORModel5 0.59(0.46-0.76); p < 0.05]. CONCLUSION: To our knowledge, this is the first analysis assessing receipt of NCCN guideline-concordant treatment by ICE, a validated measure for structural racism. While much literature emphasizes neighborhood-level barriers to treatment, our results demonstrate that compared to NHW patients, NHB patients are less likely to receive NCCN guideline-concordant breast cancer treatment, independent of economic or residential segregation. Our study suggests that there are potential unaccounted individual or neighborhood barriers to receipt of appropriate care that go beyond economic or residential segregation.

BACKGROUND: Neighborhood disadvantage has been linked to cognitive impairment, but little is known about the effect of neighborhood disadvantage on long-term cancer-related memory decline. METHODS: Incident cancer diagnosis and memory (immediate and delayed recall, combined with proxy-reported memory) were assessed at biennial interviews in the US Health and Retirement Study (N = 13,293, 1998-2016). Neighborhood disadvantage was measured using the National Neighborhood Data Archive disadvantage index, categorized into tertiles (T1: least disadvantaged-T3: most disadvantaged). Linear mixed-effects models estimated the standardized memory trajectories in participants with or without cancer, by neighborhood disadvantage. RESULTS: Living in more disadvantaged neighborhoods was associated with worse mean memory function and steeper memory declines, regardless of cancer status. An incident cancer diagnosis was associated with an acute memory drop for those living in least disadvantaged neighborhoods but not more disadvantaged neighborhoods [T1: -0.05, 95% confidence interval (CI): -0.08, -0.01; T3: -0.13, 95% CI: -0.06, 0.03]. Cancer survivors in the least disadvantaged neighborhoods had a slight memory advantage in the years prior to diagnosis (T1: 0.09, 95% CI: 0.04, 0.13) and after diagnosis (T1: 0.07, 95% CI: 0.01, 0.13). CONCLUSIONS: An incident cancer diagnosis among those living in the least disadvantaged neighborhoods was associated with an acute memory drop at the time of diagnosis and a long-term memory advantage before and after diagnosis compared with cancer-free individuals in similar neighborhoods. IMPACT: These findings could inform interventions to promote cancer survivor's long-term aging. Future studies should investigate the social and biological pathways through which neighborhood socioeconomic status could influence cancer-related memory changes.

PURPOSE: Cardiovascular risk factors (CVRFs) are associated with increased risk for cognitive impairment and decline in the general population, but less is known about how CVRFs might influence cognitive aging among older cancer survivors. We aimed to determine how CVRFs prior to a cancer diagnosis affect post-cancer diagnosis memory aging, compared to cancer-free adults, and by race/ethnicity. METHODS: Incident cancer diagnoses and memory (immediate and delayed recall) were assessed biennially in the US Health and Retirement Study (N = 5,736, 1998-2018). CVRFs measured at the wave prior to a cancer diagnosis included self-reported cigarette smoking, obesity, diabetes, heart disease, hypertension, and stroke. Multivariable-adjusted linear mixed-effects models evaluated the rate of change in standardized memory score (SD/decade) post-cancer diagnosis for those with no, medium, and high CVRFs, compared to matched cancer-free adults, overall and stratified by sex and race/ethnicity. RESULTS: Higher number of CVRFs was associated with worse baseline memory for both men and women, regardless of cancer status. Cancer survivors with medium CVRFs had slightly slower rates of memory decline over time relative to cancer-free participants (0.04 SD units/decade [95% CI: 0.001, 0.08]). Non-Hispanic Black (NHB) and Hispanic cancer-free participants and cancer survivors had worse baseline memory than their Non-Hispanic White (NHW) counterparts. CONCLUSIONS: CVRFs were associated with worse baseline memory function, but not decline, for cancer-free adults and cancer survivors. Racial disparities were largely similar between cancer survivors and cancer-free adults. IMPLICATIONS FOR CANCER SURVIVORS: These findings may inform hypotheses about pre-diagnosis multimorbidity and cognitive aging of cancer survivors from diverse groups.

ObjectivesTo assess how cognitive trajectories from mid-to-later life relate to wealth change, overall and by mid-life income. Methods: Data were from participants (51-64 years) in the 2000-2018 U.S. Health and Retirement Study who were cognitively healthy at baseline (year 2000; unweighted n = 3821). Longitudinal latent class analyses generated cognitive and wealth trajectories, independently, and multinomial logistic regressions estimated the association between cognitive trajectories and wealth profiles, overall and by median income. Results: We identified three cognitive: cognitively healthy (CH), increasing cognitive impairment (ICI), and increasing dementia (ID) and four wealth profiles: stable wealth loss (SWL), delayed gradual wealth loss (DGWL), stable wealth gain (SWG), and gradual wealth gain (GWG). The ID group had higher probability of being in the SWL group and lower probability of SWG, which was more pronounced in respondents with greater median income. Discussion: Individuals with ID may be vulnerable to wealth loss, particularly for middle-class households.
RESUMEN
BACKGROUND: Previous studies on disparities in triple-negative breast cancer (TNBC) focus on race/ethnicity, with few exploring the impact of contextual factors such as neighborhood-level income. This study evaluates the effect of neighborhood-level income on disparities in TNBC among a racially and ethnically diverse cohort, after accounting for granular individual-level risk factors of TNBC. PATIENTS AND METHODS: Patients with stage I-IV breast cancer from 2005 to 2017 were identified from our local tumor registry. The primary outcome was diagnosis of TNBC. Using 5-years estimates from the American Community Survey, we obtained median household income for each census tract which was categorized into quartiles. Mixed effects logistic regression was conducted and stratified by race and ethnicity, controlling for individual-level sociodemographic, comorbidities, and tumor characteristics. RESULTS: Among 5377 breast cancer registry patients, 16.5% were diagnosed with TNBC. The majority were Hispanic (50.1%) followed by non-Hispanic Black (NHB) (28.0%). After controlling for individual-level covariables including race and ethnicity, comorbidities, and tumor characteristics, women from low-income neighborhoods had increased odds of TNBC compared with other breast cancer subtypes, compared with those in high-income neighborhoods [odds ratio (OR) 1.33; 95% confidence interval (CI) 1.04, 1.70, p < 0.001]. In stratified analyses, NHB patients from low-income neighborhoods had two times the odds of TNBC diagnosis compared with those from high-income neighborhoods (OR 2.11; 95% CI 1.02, 4.37). CONCLUSION: We found that living in a low-income neighborhood is associated with an increased odds of TNBC independent of granular individual-level TNBC risk factors, particularly NHB race. More striking, NHB living in low-income neighborhoods had increased odds of TNBC compared with NHB living in high-income neighborhoods. Our results suggest potential unaccounted gene-environment and/or social (api)genomic interactions between neighborhood-level income and TNBC subtype development.

INTRODUCTION: We compared gender disparities in later-life memory, overall and by education, in India and the United States (US). METHODS: Data (N = 7443) were from harmonized cognitive assessment protocols (HCAPs) in the Longitudinal Aging Study of India-Diagnostic Assessment of Dementia (LASI-DAD; N = 4096; 2017-19) and US Health and Retirement Study HCAP (HRS-HCAP; N = 3347; 2016-17). We derived harmonized memory factors from each study using confirmatory factor analysis. We used multivariable-adjusted linear regression to compare gender disparities in memory function between countries, overall and by education. RESULTS: In the United States, older women had better memory than older men (0.28 SD-unit difference; 95% CI: 0.22, 0.35). In India, older women had worse memory than older men (-0.15 SD-unit difference; 95% CI: -0.20, -0.10), which attenuated with increasing education and literacy. CONCLUSION: We observed gender disparities in memory in India that were not present in the United States, and which dissipated with education and literacy.

Loneliness is a growing public health concern worldwide. We characterized the association between cumulative loneliness and subsequent all-cause mortality, using data from 9,032 participants aged 50+ in the population-based US Health and Retirement Study (HRS) from 1996 to 2019. Loneliness status (yes; no) was measured biennially from 1996 to 2004, and we categorized the experience of cumulative loneliness over the 8-y period as never, one time point, two time points, and ≥three time points. A multivariable-adjusted age-stratified Cox proportional hazards regression model was fitted to examine the association between cumulative loneliness from 1996 to 2004 and all-cause mortality from 2004 to 2019. Excess deaths due to each category of cumulative loneliness were calculated. Compared to those who never reported loneliness from 1996 to 2004, participants experiencing loneliness at one time point, two time points, and ≥three time points respectively had 1.05 (95% CI: 0.96 to 1.15), 1.06 (95% CI: 0.95 to 1.19), and 1.16 (95% CI: 1.02 to 1.33) times higher hazards of mortality from 2004 to 2019 (P trend = 0.01). These results correspond to 106 (95% CI: 68 to 144), 202 (95% CI: 146 to 259), and 288 (95% CI: 233 to 343) excess deaths per 10,000 person-years, for those experiencing loneliness at each of one, two, or ≥three time points from 1996 to 2004. Cumulative loneliness in mid-to-later life may thus be a mortality risk factor with a notable impact on excess mortality. Loneliness may be an important target for interventions to improve life expectancy in the United States.

Objectives: This literature review aims to assess the current state of the field linking neighborhood environments to later-life health and wellbeing. Methods: We used electronic databases (e.g., PubMed, Google Scholar, and ProQuest) to search for studies published between 2010 and 2022 examining associations between neighborhood built environmental variables and later-life physical, cognitive, mental, and social health outcomes. Results: Among 168 studies reviewed, the majority were quantitative (n = 144) and cross-sectional (n = 122). Neighborhood environmental variables significantly associated with later-life health outcomes included population density/rurality, walkability/street connectivity, access to services and amenities, neighborhood quality and disorder, and parks/green/blue/open space. Neighborhoods operated through behavioral and biological pathways including hazardous exposures, affective states (e.g., stress and restoration), and lifestyle (e.g., exercise, socialization, and diet). Discussion: Neighborhoods and healthy aging research is a burgeoning interdisciplinary and international area of scholarship. Findings can inform upstream community interventions and strengthen clinical care.
RESUMEN
BACKGROUND AND OBJECTIVES: The COVID-19 pandemic placed unprecedented stress on older adults. Resiliency could mitigate deleterious effects of pandemic stressors. We described trends in resilience among US adults aged 50-80 years approximately one and half years after the onset of the pandemic, compared with before the pandemic, and evaluated associations between relationships and resilience. RESEARCH DESIGN AND METHODS: Data were from the National Poll on Healthy Aging (N=2,100) in August 2021. Respondents rated their resiliency as compared with before the pandemic (more, about the same, or less) and different types of relationships (spouse/partner, friends, neighbors) as sources of joy and/or stress during the pandemic (a lot, some, very little, and not at all). Multinomial logistic regressions (complete-case analysis) estimated the relationships between each joyful and stressful relationships and resiliency. RESULTS: Most participants reported feeling as resilient as before the pandemic (70.6%) with 14.5% feeling less resilient. More women than men felt less resilient than before the pandemic (16.7% vs. 12.8%, p=0.006). Feeling a lot of stress from one's spouse or neighbors was associated with increased likelihood of feeling less resilient than before the pandemic (OR=3.7; 95% CI: 1.8, 7.7 and OR=4.5; 95% CI: 1.5, 13.9, respectively) which was stronger among women (OR=15.1; 95% CI: 4.8, 45.6) than men (OR=1.03; 95% CI: 0.4, 2.7). DISCUSSION AND IMPLICATIONS: Social relationships may have been more important for women than for men in supporting resiliency during the pandemic. Understanding patterns of resiliency can help to inform policymaking and support the well-being of older adults.
RESUMEN
We aimed to determine the influence of modifiable health behaviors prior to a cancer diagnosis on functional aging trajectories after diagnosis among middle-aged and older cancer survivors in the United States. Data were from biennial interviews with 2,717 survivors of a first incident cancer diagnosis after age 50 in the population-based US Health and Retirement Study from 1998 to 2016. Smoking status, alcohol use, and vigorous physical activity frequency were assessed at the interview prior to cancer diagnosis. Confounder-adjusted multinomial logistic regression was used to determine the associations between each pre-diagnosis health behavior and post-diagnosis trajectories of memory function and limitations to activities of daily living (ADLs), which were identified using group-based trajectory modeling. Overall, 20.7 % of cancer survivors were current smokers, 30.6 % drank alcohol, and 27.1 % engaged in vigorous physical activity >=once a week prior to their diagnosis. In the years following diagnosis, those who had engaged in vigorous physical activity > once a week were less likely to have a medium-high (OR: 0.5; 95 % CI: 0.2-0.9) or medium-low memory loss trajectories (OR: 0.6; 95 % CI: 0.3-1.0) versus very low memory loss trajectory, and were less likely to have a high, increasing ADL limitation trajectory (OR: 0.3; 95 % CI: 0.2, 0.6) versus no ADL limitation trajectory. Vigorous physical activity, but not smoking or alcohol use, was associated with better post-diagnosis functional aging trajectories after a first incident cancer diagnosis in mid-to-later life in this population-based study. Identification of modifiable risk factors can inform targeted interventions to promote healthy aging among cancer survivors.
RESUMEN
INTRODUCTION: The study objective was to investigate the association between loneliness duration and memory function over a 20-year period. METHODS: Data were from 9032 adults aged ≥50 in the Health and Retirement Study. Loneliness status (yes vs. no) was assessed biennially from 1996 to 2004 and its duration was categorized as never, 1 time point, 2 time points, and ≥3 time points. Episodic memory was assessed from 2004 to 2016 as a composite of immediate and delayed recall trials combined with proxy-reported memory. Mixed-effects linear regression models were fitted. RESULTS: A longer duration of loneliness was associated with lower memory scores (P < 0.001) and a faster rate of decline (P < 0.001). The association was stronger among adults aged ≥65 than those aged <65 (three-way interaction P = 0.013) and was stronger among women than men (three-way interaction P = 0.002). DISCUSSION: Cumulative loneliness may be a salient risk factor for accelerated memory aging, especially among women aged ≥65. HIGHLIGHT: A longer duration of loneliness was associated with accelerated memory aging. The association was stronger among women than men and among older adults than the younger. Reducing loneliness in mid- to late life may help maintain memory function.

PURPOSE: We aimed to identify prototypical functional aging trajectories of US cancer survivors aged 50 and older, overall and stratified by sociodemographic and health-related characteristics. METHODS: Data were from 2986 survivors of a first incident cancer diagnosis (except non-melanoma skin cancer) after age 50 in the population representative U.S. Health and Retirement Study from 1998-2016. Cancer diagnoses, episodic memory function, and activity of daily living (ADL) limitations were assessed at biennial study interviews. Using time of cancer diagnosis as the baseline, we used group-based trajectory modeling to identify trajectories of memory function and ADL limitations following diagnosis. RESULTS: We identified five memory loss trajectories (high: 8.4%; medium-high: 18.3%; medium-low: 21.5%; low: 25.5%; and, very low: 26.2%), and four ADL limitation trajectories (high/increasing limitations: 18.7%; medium limitations: 18.7%; low limitations: 8.14%; no limitations: 60.0). The high memory loss and high/increasing ADL limitation trajectories were both characterized by older age, being female (52% for memory, 58.9% for ADL), having lower pre-cancer memory scores, and a higher prevalence of pre-cancer comorbidities including stroke (30.9% for memory and 29.7% for ADL), hypertension (64.7% for memory and 69.8 for ADL), and depressive symptoms. In joint analyses, we found that generally those with higher memory were more likely to have fewer ADL limitations and vice versa. CONCLUSION: Older cancer survivors experience heterogeneous trajectories of functional aging that are largely characterized by comorbidities prior to diagnosis. IMPLICATION FOR CANCER SURVIVORS: Results can help identify older cancer survivors at increased risk for accelerated functional decline.

Having a family history of alcohol (FH+) use is a well-documented risk factor for alcohol use and alcohol related problems. However, there are limited studies examining the impact of FH + on current alcohol use among Latino immigrants. This study aimed to determine the influence of having a FH + on current alcohol use among Latino immigrants and the influence of alcohol outcome expectancies (AOEs) and acculturation on this relationship. This is a longitudinal secondary data analysis of data from the Recent Latino Immigrant Study (RLIS), the first community-based cohort study to examine pre- to post-immigration alcohol use trajectories of young adult Latino immigrants. Linear mixed models were performed to assess the association between various pre- and post-immigration factors and alcohol use among Latino immigrants. There were 518 young adult Latino immigrants with 18.7% reporting a FH + with those with a FH + having higher mean AUDIT score compared to those without (4.74 vs. 3.81; p = 0.028). Positive AOEs were associated with increase AUDIT scores. FH + individuals with greater positive AOEs experienced higher AUDIT scores compared to FH- individuals. Family cohesion was protective against alcohol use while endorsement of Americansism was associated with increased alcohol use. Theses results provide the framework for more in-depth exploration regarding the influences of FH+, AOEs, and acculturation have on the alcohol use among Latino immigrants. Future longitudinal research studies should account for whether traditional cultural values mediate or moderate the relationship between a FH+, AOE, and alcohol use of Latino immigrants.

BACKGROUND: The global population of older cancer survivors is growing. However, the intersections of aging-related health risks across the cancer control continuum are poorly understood, limiting the integration of aging into cancer control research and practice. The objective of this study was to review the state of science and provide future directions to improve the quality of evidence in 6 priority research areas in cancer and aging. METHODS: The authors identified priority research areas in cancer and aging through an evidence-based Research Jam process involving 32 investigators and trainees from multiple disciplines and research centers in aging and cancer; then, they conducted a narrative review of the state of the science and future directions to improve the quality of evidence in these research areas. Priority research areas were defined as those in which gaps in scientific evidence or clinical practice limit the health and well-being of older adults with cancer. RESULTS: Six priority research areas were identified: cognitive and physical functional outcomes of older cancer survivors, sampling issues in studies of older cancer survivors, risk and resilience across the lifespan, caregiver support and well-being, quality of care for older patients with cancer, and health disparities. Evidence in these areas could be improved through the incorporation of bias reduction techniques into longitudinal studies of older cancer survivors, novel data linkage, and improved representation of older adults in cancer research. CONCLUSIONS: The priority research areas and methodologies identified here may be used to guide interdisciplinary research and improve the quality of evidence on cancer and aging.

BACKGROUND: It is unknown whether an incident cancer diagnosis differentially impacts acute and long-term memory aging between older White and Black Americans. METHODS: Incident cancer diagnoses and memory (immediate and delayed recall, combined with proxy-reported memory) were assessed at biennial study interviews in the US Health and Retirement Study (N=14,235, 1998-2016). We used multivariable segmented linear mixed-effects models to evaluate the rate of change in standardized memory score (SD/decade) in the years before, acutely at the time of, and in the years following an incident cancer diagnosis, compared to cancer-free adults, by race. RESULTS: Black participants experienced faster memory decline than White participants (cancer-free group: -1.211 vs. -1.077; P<0.0001). An incident cancer diagnosis was associated with an acute memory drop in White, but not Black participants (-0.065 vs. 0.024; P<0.0001). However, White cancer survivors experienced slower memory decline than cancer-free White adults before and after diagnosis, but this memory advantage was not observed among Black cancer survivors. CONCLUSIONS: Racial disparities in memory aging are not modified by an incident cancer diagnosis. The acute cancer-related memory decline and long-term memory advantage experienced by White, but not Black, cancer survivors relative to cancer-free older adults, requires further investigation.

OBJECTIVE: To analyze the effect of economic and racial/ethnic residential segregation on breast cancer-specific survival (BCSS) in South Florida, a diverse metropolitan area that mirrors the projected demographics of many United States regions. SUMMARY BACKGROUND DATA: Despite advances in diagnosis and treatment, racial and economic disparities in BCSS. This study evaluates these disparities through the lens of racial and economic residential segregation, which approximate the impact of structural racism. METHODS: Retrospective cohort study of stage I to IV breast cancer patients treated at our institution from 2005 to 2017. Our exposures include index of concentration at the extremes, a measurement of economic and racial neighborhood segregation, which was computed at the census-tract level using American Community Survey data. The primary outcome was BCSS. RESULTS: Random effects frailty models predicted that patients living in low-income neighborhoods had higher mortality compared to those living in high-income neighborhoods [hazard ratios (HR): 1.56, 95% confidence interval (CI): 1.23-2.00]. Patients living in low-income non-Hispanic Black and Hispanic neighborhoods had higher mortality compared to those living in high-income non-Hispanic White (NHW) neighborhoods (HR: 2.43, 95%CI: 1.72, 3.43) and (HR: 1.99, 95%CI: 1.39, 2.84), after controlling for patient characteristics, respectively. In adjusted race-stratified analysis, NHWs living in low-income non-Hispanic Black neighborhoods had higher mortality compared to NHWs living in high-income NHW neighborhoods (HR: 4.09, 95%CI: 2.34-7.06). CONCLUSIONS: Extreme racial/ethnic and economic segregation were associated with lower BCSS. We add novel insight regarding NHW and Hispanics to a growing body of literature that demonstrate how the ecological effects of structural racism-expressed through poverty and residential segregation-shape cancer survival.

Introduction: Shifts in the sociopolitical context of Latin America have led to steep increases in recent Latinx immigrants (RLI) arriving in the US within the context of forced migration. Yet, little is known about how adverse experiences of RLIs before and after immigration may impact their health including drug use. The purpose of this study was to examine prescription drug and cannabis use before and just after immigration among RLIs and how this drug use is influenced by pre-and post-immigration factors. Methods: This study utilized baseline data from a study examining pre- to post-immigration drinking and driving trajectories among RLI in the United States (US). Baseline criteria included: self-identifying as a Latinx immigrant, 18 - 34 years old, who recently immigrated from a Latin American country. Multivariate logistic regression was conducted to determine predictors of drug use both prior to and after immigrating. Results: There were 540 RLI, 50.2% male and 47.8% subjected to forced migration. Prescription and illicit drug use decreased post-immigration with sedatives being the most common. Higher levels of education was associated with increased odds of pre-immigration prescription drug use and cannabis use. Those experiencing forced migration were more likely to engage in prescription drug use before and after immigration, while no associations were found for cannabis use. Conclusion: Findings suggest a need for increased substance use and mental health services among RLIs arriving within the context of forced migration. More research is needed to understand the trajectories of drug use among RLI as their time in the US increases.

Background/Purpose: Emerging adulthood is an important time where substance use often peaks. Neighborhood Latinx ethnic density could be protective against negative health behaviors. Most studies on neighborhood ethnic density have focused on census-level aggregate measures, however perception of the neighborhood ethnic density could differ from objectively measured neighborhood density. This study investigated the effects of neighborhood ethnic density, both perceived ethnic and objectively measured ethnic density, on hazardous alcohol use among Latinx emerging adults in Maricopa County Arizona and Miami-Dade County Florida by gender. Methods: 200 Latinx emerging adults residing in Arizona and Florida completed a cross-sectional survey. Inclusion criteria were being age 18-25, self-identify as Latinx, and currently living in Maricopa County or Miami-Dade County. Data were analyzed using multivariate logistic regression and moderation analyses. Results: There was a statistically significant difference between perceived and objective ethnic density (Kappa = 0.353, p < 0.001). When ethnic density was measured objectively, alcohol use severity was statistically significantly lower for individuals living in highly ethnically dense neighborhoods (OR: 0.34, 95% CI: 0.12, 0.92). However, this association was only found for women in moderation analyses. There was no statistically significant association between perceived ethnic density and alcohol use severity. Conclusion: The present study found a statistically significant decrease in alcohol use severity among Latinx emerging adults who live in highly ethnically dense neighborhoods after adjusting for covariates. Future research should investigate the potential mechanisms in which these neighborhoods protect against alcohol use severity among Latinx emerging adults.
