Race and Objective Social Isolation: Older African Americans, Black Caribbeans, and Non-Hispanic Whites

Latent profiles and transitions of social isolation among older adults and their influencing factors: a person-centered approach

Introduction

In the context of global aging, it is crucial to understand the heterogeneity, changing trends, and influencing factors of social isolation in older people.

Methods

7198 older people over 60 in China Longitudinal Aging Social Survey in 2016 and 2018 were analyzed, using Latent Profile Analysis, Latent Transition Analysis, and multiple logistic regression analysis.

Results

The study identified five categories of social isolation among older people; the rural, widowed, with low daily living activity ability, and with low cognitive ability were more likely to belong to the social isolation category; the stability of various profiles of social isolation was strong, but the high-level social network category had the danger of changing to the medium-level social network category and the social isolation risk category; over time, those with high daily living activity ability moved into worse social isolation categories, while those with high cognitive ability moved into better categories.

Discussion

The social isolation status of the older adult had group heterogeneity and transitioned over time. The findings provide empirical evidence for taking targeted measures based on the influencing factors in older people to achieve successful aging.

Racial and Ethnic Disparities in the 11-Year Bidirectional Relationship Between Dementia and Social Isolation Among Community-Dwelling Older Adults

OBJECTIVES

This study aims to investigate the longitudinal impact of dementia on social isolation and vice versa, with a focus on racial and ethnic variations in these relationships.

METHODS

Data from 4,403 adults aged 65 and older were gathered from the National Health and Aging Trends Study (2011-2021). Dementia was categorized as no, possible, or probable, and social isolation was classified as socially isolated or not. Two cohorts were formed based on baseline social isolation and baseline dementia status. Cox proportional hazards regression models were used to evaluate the impact of baseline social isolation on subsequent dementia and vice versa, adjusting for potential covariates. Models were stratified by race/ethnicity. All analyses were conducted using STATA/MP version 17.0 RESULTS: In fully adjusted models, participants with dementia had a 1.40-fold higher likelihood of developing social isolation over the 10-year follow-up period. Those with baseline social isolation had a 7.21-fold higher likelihood of developing dementia over time. Racial and ethnic differences were observed in the influence of dementia on social isolation incidence. Non-Hispanic whites showed a statistically significant increase, while other racial and ethnic groups did not exhibit significant changes. Conversely, the impact of social isolation on dementia incidence was significant across all racial and ethnic groups.

DISCUSSION

Dementia and social isolation are bidirectionally linked among older adults, with notable racial and ethnic differences. Dementia increases the risk of social isolation, particularly among non-Hispanic whites, while social isolation significantly elevates the risk of developing dementia across all racial and ethnic groups. These findings underscore the need for targeted interventions to address social isolation and cognitive decline, considering racial and ethnic differences to improve outcomes for seniors.

Social Isolation and Depressive Symptoms of Older Chinese Immigrants: The Mediating Effect of Activity Engagement

Objectives: This study aimed to examine the differential impacts of two forms of social isolation on depressive symptoms and investigate the mediating role of activity engagement among older Chinese immigrants. Methods: Data were from four waves of the Population Study of Chinese Elderly in Chicago Study (PINE) (N = 2,075). Social disconnectedness was measured by social network size and range, living arrangement, and marital status. Perceived isolation was measured by loneliness and lack of social support. Activity engagement was assessed by engagement with various social and cognitive activities. Results: The latent growth curve models indicated that social disconnectedness and perceived isolation were associated with a higher initial level of depressive symptoms. However, perceived isolation predicted a faster decline in depressive symptoms. Activity engagement had significant mediating effects on the relationships. Discussion: Efforts should focus on reducing social isolation and providing opportunities for activity engagement to mitigate depression among older Chinese immigrants.

Racial Differences in the Association Between Loneliness and Cognitive Impairment Among Older Black and White Men

BACKGROUND

Loneliness is a biopsychosocial stressor linked to poor health outcomes including dementia. Few studies have focused on this association among men and even fewer have examined racial disparities in loneliness and cognitive functioning among this group. The purpose of this study was to examine racial differences in the association between loneliness and cognitive functioning among men in the 2016 wave of the Health and Retirement Study.

METHODS

This cross-sectional study included Black and White men who completed the core questionnaire and the Leave Behind Questionnaire (n = 2 227). Any cognitive impairment was the primary outcome and was measured by a dichotomous variable derived from a modified version of the Telephone Interview for Cognitive Status. Loneliness was the primary independent variable and was derived from the 3-item University of California, Los Angeles (UCLA) Loneliness Scale. Modified Poisson regression models with robust standard errors were estimated to generate prevalence ratios (PRs) and corresponding 95% confidence intervals (CIs).

RESULTS

Black men comprised 18.4% of the study sample; however, the proportion of this group with scores indicating cognitive impairment (35.9%) doubled the corresponding percentage of white men (17.6%). Findings from race-stratified modified Poisson regression models indicated that loneliness was associated with a higher prevalence of any cognitive impairment for White men (PR = 1.24, CI: 1.05-1.47), but not for Black men (PR = 0.92, CI: 0.73-1.16).

CONCLUSIONS

Our results underscore the complexity of race when investigating the association between loneliness and cognitive impairment among older men. Additional studies are needed to further examine how loneliness may have racially distinct implications for cognitive outcomes among the population.

Racial and ethnic disparities in social isolation and 11-year dementia risk among older adults in the United States

AIMS

Social isolation has been implicated in the development of cognitive impairment, but research on this association remains limited among racial-ethnic minoritized populations. Our study examined the interplay between social isolation, race-ethnicity and dementia.

METHODS

We analyzed 11 years (2011-2021) of National Health and Aging Trends Study (NHATS) data, a prospective nationally representative cohort of U.S. Medicare beneficiaries aged 65 years and older. Dementia status was determined using a validated NHATS algorithm. We constructed a longitudinal score using a validated social isolation variable for our sample of 6,155 community-dwelling respondents. Cox regression determined how the interaction between social isolation and race-ethnicity was associated with incident dementia risk.

RESULTS

Average longitudinal frequency of social isolation was higher among older Black (27.6%), Hispanic (26.6%) and Asian (21.0%) respondents than non-Hispanic White (19.1%) adults during the 11-year period (t = -7.35, p < .001). While a higher frequency of social isolation was significantly associated with an increased (approximately 47%) dementia risk after adjusting for sociodemographic covariates (adjusted hazard ratio [aHR] = 1.47, 95% CI [1.15, 1.88], p < .01), this association was not significant after adjusting for health covariates (aHR = 1.21, 95% CI [0.96, 1.54], p = .11). Race-ethnicity was not a significant moderator in the association between social isolation and dementia.

CONCLUSIONS

Older adults from racial-ethnic minoritized populations experienced a higher longitudinal frequency of social isolation. However, race-ethnicity did not moderate the positive association observed between social isolation and dementia. Future research is needed to investigate the underlying mechanisms contributing to racial-ethnic disparities in social isolation and to develop targeted interventions to mitigate the associated dementia risk.

Neighborhood social cohesion and physical disorder in relation to social isolation in older adults: racial and ethnic differences

BACKGROUND

Neighborhood factors of social isolation have been understudied, hindering efforts to reduce social isolation at the neighborhood level. This study aims to investigate the longitudinal effects of neighborhood social cohesion and physical disorder on social isolation in community-dwelling older adults, as well as to examine whether race/ethnicity moderates the neighborhood-isolation relationship.

METHODS

We used 11-year data from the National Health and Aging Trend Study, a longitudinal national study of Medicare beneficiaries aged 65 and older. Social isolation was measured through a summary score across four domains: marital/partner status, family and friend contact, religious attendance, and club participation. A series of weighted mixed-effects logistic regression models were performed to test the study aims. Sample sizes ranged from 7,303 to 7,291 across individual domains of social isolation.

RESULTS

Approximately 20% of participants reported social isolation. Findings indicated a negative association between neighborhood social cohesion and social isolation. Higher levels of neighborhood social cohesion were longitudinally associated with lower odds of social isolation (odds ratio [OR] = 0.52, 95% CI: 0.47-0.58). Yet, the presence of neighborhood physical disorder was associated with an increased risk of overall social isolation ([OR] = 1.2, 95% CI: 1.00, 1.44). Race/ethnicity significantly moderated the effects of neighborhood social cohesion and physical disorder on social isolation. The odds of no in-person visits associated with neighborhood social cohesion are smaller among Black adults compared to White adults. Black adults had constantly lower odds of isolation from religious attendance compared to White adults regardless of the level of neighborhood social cohesion. Hispanic adults had decreased odds of having no friends associated with signs of physical disorder, while no associations were found among older White adults. White adults had higher odds of isolation from in-person visits when living in neighborhoods with signs of physical disorder, whereas no association was observed among older Black and Hispanic adults.

CONCLUSIONS

This study elucidates the role of neighborhood characteristics in shaping social isolation dynamics among older adults. Furthermore, the observed moderation effects of race/ethnicity suggest the need for culturally sensitive interventions tailored to address social isolation within specific neighborhood and racial contexts.

Correlates of Loneliness and Social Isolation among Older Adults during the COVID-19 Outbreak: A Comprehensive Assessment from a National United States Sample

This study examined the correlates of loneliness and social isolation among older adults in the United States (U.S.) during the COVID-19 outbreak. We analyzed data from the 2020 National Health and Aging Trends Study, a nationally representative sample of 3257 U.S. older adults aged 65 years and older. We analyzed and identified the sociodemographic, health, social support, and community correlates of loneliness, higher loneliness during versus before the COVID-19 outbreak, and social isolation using weighted multiple logistic regression models. About 35.2% of U.S. older adults reported loneliness during the COVID-19 outbreak, 21.9% reported higher loneliness compared to before the COVID-19 outbreak, and 32.8% were socially isolated during the outbreak. Correlates for increased odds of loneliness included female gender, higher education, physical activity, depression, anxiety, functional limitations, and virtual communication access (only for higher loneliness during COVID-19 outbreak). Correlates for increased odds of social isolation included higher age, non-Hispanic Black, Hispanic, higher number of household children, and metropolitan residence. Our findings provide insights into evidence-based approaches to address social disconnection among U.S. older adults. The wide range of sociodemographic, health, social support, and community correlates identified in this study warrants multifaceted interventions that traverse individual, community, and societal levels to address the loneliness and social isolation epidemic.

Racial/Ethnic Differences in Loneliness Among Older Adults: The Role of Income and Education as Mediators

Background and Objectives

Loneliness is a major public health concern; however, limited research has examined the mechanisms contributing to racial/ethnic inequities in loneliness. Race/ethnicity has been hypothesized to be a distal factor influencing loneliness, and racial/ethnic inequities in loneliness may be attributable to socioeconomic factors (e.g., income and education). Our study seeks to confirm these hypotheses by examining mechanisms that contribute to racial/ethnic inequities in loneliness. In other words, if racial/ethnic differences in loneliness among older adults are mediated by income and education.

Research Design and Methods

Data came from the Health and Retirement Study Leave-Behind Questionnaire, 2014-2016. Loneliness was measured by the UCLA 3-item loneliness scale. Race/ethnicity categories were White, Black, and Hispanic/Latino. The mediator variables were household income and education. Multivariable linear regression models were used to determine differences in loneliness by race/ethnicity. The Karlson-Holm-Breen (KHB) mediation method was used to determine if income and education mediated racial/ethnic differences in loneliness.

Results

In models examining income and education together, a complete mediation was found between White and Black older adults, in that income and education completely mediated differences in loneliness between these groups. A partial mediation was found between White and Hispanic, and Black and Hispanic older adults. When examining income and education separately, we found that income solely accounted for racial/ethnic differences in loneliness compared to education.

Discussion and Implications

Our study is the first to explicitly determine if socioeconomic factors mediate race/ethnicity differences in loneliness among a national sample of older adults. These findings illustrate that income may have greater proximate effects for loneliness among older adults in comparison to education. Additionally, these findings can inform evidence-based interventions to reduce loneliness among older adults. Interventions that enhance quality of life and provide opportunities for socialization for racialized low-income older adults may help decrease racial/ethnic inequities in loneliness.

Social connectedness in older Urban African-American adults during the COVID-19 pandemic: the roles of education and partnership

OBJECTIVE

This study examined education, partnership status, and the moderating role of the lockdown period on social connectedness during the COVID-19 pandemic in a sample of urban African-American older adults.

METHODS

Five hundred thirty-four African-American adults living in Detroit (91.0% female, Mage = 74.53) reported demographic information pre-pandemic and answered one social connectedness questionnaire between April and December 2020.

RESULTS

Participants interviewed after the lockdown (post-June 2020) reported more loneliness than those interviewed during the lockdown (April-June, 2020). Married/partnered participants reported less loneliness and social isolation. Loneliness did not differ between those with high education levels interviewed during the lockdown compared to post-lockdown. However, among individuals with low education levels, those interviewed after the lockdown reported more loneliness than those interviewed during the lockdown period.

CONCLUSION

Our findings suggest partnership status is associated with more social connectedness during the pandemic and education accentuates the effects of forced isolation related to loneliness among urban African-American older adults.

Increases in loneliness among Older Americans Act participants during COVID-19

Loneliness is increasingly understood as a public health crisis, and older adults are experiencing particularly severe impacts. Social distancing efforts during the COVID-19 pandemic may have increased loneliness among older adults. Guided by the Social Ecological Model, this study uses two cross-sectional waves of the National Survey of Older Americans Act Participants (NSOAAP) from 2019 and 2021 to expand understanding and identify possible points of intervention to increase social support for vulnerable older adults. Results reveal that while home-delivered meal participants have higher levels of loneliness than congregate meal participants, levels of loneliness did not increase during the COVID-19 pandemic and their loneliness levels did not differ significantly by age, geographic location, or living arrangement. Congregate meal participants' loneliness increased during the first year of the pandemic, particularly for participants aged 65-74, those living in suburban or rural areas, and those living alone. These findings suggest opportunities for policymakers and aging services providers who seek to increase social engagement among older adults who participate in Older Americans Act (OAA) nutrition programs. The evidence suggests a need for increased social engagement initiatives through OAA programs that prioritize social support for groups who are disproportionately burdened by loneliness.

Discrimination and social isolation among African Americans: The moderating role of skin tone

OBJECTIVES

Discrimination is an urgent public health problem. A number of major cities and counties across the United States has declared racism a public health crisis. While there is a growing body of research on the discrimination-health connection, less is known regarding the social relational consequences of discrimination. The present study addresses this knowledge gap by investigating the relationship between discrimination, skin tone, and objective and subjective social isolation using a nationally representative sample of African Americans.

METHOD

This analysis was based upon the African American subsample (N = 3,570) of the National Survey of American Life. Discrimination was assessed with the Everyday Discrimination Scale. Objective and subjective isolation differentiated between respondents who were (a) socially isolated from both family and friends, (b) socially isolated from friends only, (c) socially isolated from family only, and (d) not socially isolated. Skin tone was self-reported. Multinomial logistic regression analyses were used to test the study hypotheses.

RESULTS

The analyses indicated that more frequent discriminatory experiences were associated with increased risk for subjective and objective social isolation. Skin tone moderated the association between discrimination and subjective isolation; the discrimination-isolation relationship was stronger among participants with darker skin tones.

CONCLUSIONS

These findings shed light on African Americans' nuanced experiences with discrimination and colorism. Further, the data demonstrate heterogeneity in the vulnerability to the adverse effects of discrimination within the African American population; the relationship between discrimination and subjective isolation was stratified by skin tone. This underscores the well-documented and persistent racialized social stratification system in the United States (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Depression, Sleep Health & Sociodemographic Correlates in a Nationwide Survey: Implications for Depression Treatment During the COVID-19

Purpose

The COVID-19 pandemic has had a profound impact on mental health worldwide, with depression and sleep problems among the most common issues experienced by many individuals. Depression can lead to sleep problems, which can increase the risk of developing depressive symptoms. However, it is unclear which United States (US) sub-population was most affected by depression and sleep problems during the pandemic.

Methods

We conducted a secondary analysis using self-reported data from the 2021 National Health Interview Survey (NHIS), focusing on adults aged 18 years and above (n=29,763). We utilized self-reported responses to questions about prescription medication and frequency of depressive feelings to determine participants' depression status. Appropriate weights were applied to account for the sampling design of the surveys. Our analysis involved descriptive statistics and chi-squared tests to compare sociodemographic, clinical, behavioral, and sleep-related characteristics between US adults with and without depression. Additionally, logistic regression was used to examine the associations between sleep duration, sleep quality and depression.

Results

The overall prevalence of depression in our sample was 44.4%. It were higher in certain demographic groups, including younger adults (18-39 years, 47.7%), non-Hispanic whites (47.9%), females (50.1%), those at the lower income bracket (52.2%), those with no college or degree (48.7%) uninsured individuals (45.2%), and those reporting poor general health (71.9%). Individuals with depression had a 12% increased odds of experiencing short sleep (aOR: 1.12, 95% CI:1.04-1.20, p<0.001), 34% increased odds of experiencing long sleep (aOR: 1.34, 95% CI: 1.20-1.50, p < 0.001) and more than 2.5 fold increased odds of reporting poor sleep quality (aOR:2.57, 95% CI: 2.40-2.78; p<0.0001). In the multivariate analysis, all variables (sex, race/ethnicity, education, health insurance coverage, marital status, general health status and use of sleep medications, smoking and alcohol use status) were significantly predictors of poor sleep quality, with the exceptions of age and family income.

Conclusion

The findings emphasize the need to address sleep health in treating depression, especially during times of public health crises.

Social Isolation, Self-Rated Health, and Self-Rated Oral Health among African Americans

Social isolation is associated with worse health; however, few studies have examined the health effects of isolation among African Americans. The purpose of this study is to evaluate associations between social isolation and self-rated physical and oral health from the National Survey of American Life, a nationally representative sample of African Americans. Social isolation was operationalized to reflect both objective isolation (lack of contact) and subjective isolation (lack of emotional closeness). Self-rated physical and oral health were regressed on objective and subjective isolation while controlling for marital status, gender, age, family income, education, and health behaviors. Poorer self-rated physical health was associated with objective isolation, while poorer self-rated oral health was associated with subjective isolation. This study contributes to the small literature of the impact of social isolation on health among African Americans; furthermore, it is the first to examine the relationship between isolation and self-rated oral health in this population.

Community-Based Strategies to Reduce Alzheimer's Disease and Related Dementia Incidence Among Rural, Racially/Ethnically Diverse Older Adults

Purpose of Review

The purpose of this paper was to address the research question "What recent advances in Alzheimer's Disease and Related Dementias (ADRD) risk reduction strategies can be tailored for rural, racially/ethnically diverse populations?" A rural resident's life story that grounded the work is shared. Next, a brief description is provided regarding ADRD risk factors of importance in rural, multicultural settings. Gaps in U.S.-based research are highlighted. Policy actions and interventions that may make a difference in alleviating rural, ADRD-related disparities are offered.

Recent Findings

More than a dozen factors, including lack of built environment, periodontitis, poor air quality, and sensory loss, were identified that are of particular relevance to rural groups. Evidence of importance to underserved residents has also emerged regarding the harmful effects of ultra-processed foods on brain health, benefits of even minimal physical activity, and importance of social engagement, on brain health.

Summary

Resident-led initiatives will be key to creating change at the community level. Health providers are also called to assist in identifying and adapting culturally specific upstream approaches, in partnership with community stakeholders. These mechanisms are vital for decreasing ADRD burdens in underserved communities facing the largest disparities in preventive care.

Including Socially Isolated Black, Older Old Adults (Aged 80 and Above) with and without Mild Cognitive Impairment in a Clinical Trial: Recruitment Strategies and Perspectives

Objective

This study describes strategies for the recruitment of socially isolated older old Black individuals to participate in the "Internet-based conversational engagement clinical trial (I-CONECT)" (Clinical Trial.gov: NCT02871921) and lessons learned in this critical population segment.

Methods

Best practice strategies to recruit the target population included mass mailings, advertisements, and direct community outreach, including the collaboration with a community group created to reach Black individuals interested in research participation. We also made protocol changes to measure recruitment criteria for older old Black adults more accurately and to increase their participation.

Results

Descriptive data related to the challenges and successes in recruiting Black participants compared to the White participants is presented. The primary site contacted 17,523 primarily White potential participants and enrolled/randomized 145 White and 2 Asian/mixed race participants (0.8%). The Midwest site contacted 12,141 Black potential participants and enrolled/randomized 39 (0.3%) participants.

Discussion

While best practices were employed, several factors complicated recruitment, including the need to adjust recruitment criteria, navigate regional regulations, and respect diverse community preferences.

Conclusion

Older old African Americans are reachable and willing to participate in research when considering their beliefs and practices, influenced by their community and experience.

Aging alone and financial insecurity predict depression: a path analysis of objective and subjective indices

OBJECTIVES

This study draws on conservation of resources theory and transactional stress theory to guide our understanding of how social isolation, financial insecurity, and social support serve as a balance of both risk and protection for late-life depression.

METHODS

Data were from the Leave-Behind Questionnaire in the 2016 (N = 4293) and 2018 (N = 4714) waves of the Health and Retirement Study. We conducted a cross-sectional path analysis via structural equation modeling, including objective and subjective perspectives. The same model was tested in both samples.

RESULTS

Both social isolation and financial insecurity were associated with depression. We found several mediating risks and protective factors of these relationships. Objective financial status affected depression through both perceived financial insecurity and perceived social isolation, whereas objective isolation affected depression through perceived social support. This mediation model was -significant after adjusting for confounders.

CONCLUSION

This study underscores the importance of investigating the balance between risk and protection for depression, in the rising number of older adults aging alone in society. Findings suggest that objective and perceived measures offer unique windows into psychological constructs. Considering both objective and subjective perspectives may provide alternative targets for subsequent interventions to improve mental health in later life.

Social Isolation: An Unequally Distributed Health Hazard

Social isolation is a potent predictor of poor health, mortality, and dementia risk. A great deal of research across national contexts provides causal evidence for these linkages and identifies key explanatory mechanisms through which isolation affects health. Research on social isolation recognizes that some people are more likely than others to be isolated, but over the past several decades, researchers have focused primarily on the consequences of isolation for health rather than a systematic assessment of the social conditions that foster isolation over the life course. In this article, we review the available evidence on inequities in social isolation and develop a conceptual framework to guide future research on structural systems that fuel social isolation over the life course. Future work in this area has the potential to identify root causes of inequality in social isolation, as well as targeted policy levers to reduce isolation in vulnerable populations.

Global prevalence of social isolation among community-dwelling older adults: A systematic review and meta-analysis

BACKGROUND

While the world's population ages, social isolation has continued to increase globally. However, no review exists on the prevalence of social isolation among community-dwelling older adults, and the global prevalence remains uncertain. This study aims to estimate the global prevalence of social isolation among community-dwelling older adults and to identify potential covariates including study characteristics (methodological diversity) or populations (clinical diversity) that contribute to the heterogeneity.

METHODS

This review searched through seven search engines and databases. The meta-analysis was conducted using the metafor package in the R software. The random-effects model was used to calculate the prevalence rates. Cochran's Q statistics and I² statistics were used to assess the statistical heterogeneity of prevalence estimates. Studies were appraised using the Newcastle-Ottawa Scale and the Grading of Recommendations, Assessment, Development, and Evaluations criteria for the quality of individual articles and the certainty of the evidence, respectively.

RESULTS

A total of 41 studies were selected from databases and reference lists. The pooled prevalence rate was 25% (95% CI: 21.0-30.0). The sample size was found to be a significant covariate of the prevalence estimate in the subgroup analysis.

CONCLUSIONS

We found 13 high-quality studies, but the overall quality of evidence very low. This study provides the prevalence of social isolation in community-dwelling older adults, identifying vulnerable groups for targeted intervention. Well-designed observational research with standard measures is recommended for future studies.

The relationship between social isolation, social support, and loneliness with cardiovascular disease and shared risk factors: A narrative review

BACKGROUND

Cardiovascular disease (CVD) is the greatest contributor to global morbidity and mortality. Poor social health plays a critical role in CVD incidence. Additionally, the relationship between social health and CVD may be mediated through CVD risk factors. However, the underlying mechanisms between social health and CVD are poorly understood. Certain social health constructs (social isolation, low social support and loneliness) have complicated the characterisation of a causal relationship between social health and CVD.

AIM

To provide an overview of the relationship between social health and CVD (and its shared risk factors).

METHOD

In this narrative review, we examined published literature on the relationship between three social health constructs (social isolation, social support, and loneliness) and CVD. Evidence was synthesised in a narrative format, focusing on the potential ways in which social health affects CVD, including shared risk factors.

RESULTS

The current literature highlights an established relationship between social health and CVD with a likelihood for bi-directionality. However, there is speculation and varied evidence regarding how these relationships may be mediated through CVD risk factors.

CONCLUSIONS

Social health can be considered an established risk factor for CVD. However, the potential bi-directional pathways of social health with CVD risk factors are less established. Further research is needed to understand whether targeting certain constructs of social health may directly improve the management of CVD risk factors. Given the health and economic burdens of poor social health and CVD, improvements to addressing or preventing these interrelated health conditions would have societal benefits.

Sociodemographic Factors and Neighborhood/Environmental Conditions Associated with Social Isolation Among Black Older Adults

Objectives: To investigate sociodemographic factors and neighborhood/environmental conditions associated with social isolation (SI) among Black older adults. Methods: We utilized data from the 2014 and 2016 Leave-Behind Questionnaire from the Health and Retirement Study (HRS LBQ) among those who self-identified as Black (N = 2.323). Outcome variables for our study included SI from adult children, other family members, friends, disengagement from social participation and religious services, being unmarried, and living alone. These indicators were also combined into an overall SI index. Critical predictors included gender, age, household income, education, employment status, neighborhood cohesion, neighborhood disorder, urbanicity, and region of residence. Results: Sociodemographic factors of gender, education and household income were significantly associated with SI indicators. Additionally, some neighborhood/environmental conditions were associated with SI indicators. Discussion: SI was found to be patterned by sociodemographic factors. These results can be used to develop effective interventions to mitigate SI among Black older adults.

Examining Between-Group Differences in Social Network Density and High-Sensitivity C-Reactive Protein in Older Adults: Implications for the Hispanic Mortality Paradox

OBJECTIVE

Hispanic/Latino(x) and African American/Black older adults experience disproportionate cardiometabolic disease burdens when compared with their non-Hispanic White counterparts. Sources of resilience such as social networks have been found to mitigate the risk of this disease and its end points like high-sensitivity C-reactive protein (hs-CRP). However, little is known about the social network infrastructure among these groups. Moreover, existing work has largely ignored the degree to which members of one's network are connected to one another (network density), which may be important for navigating structural barriers within interdependent groups. The objective of this study was to understand the association between network density and 5-year hs-CRP (blood spot) and whether this association was moderated by race-ethnicity.

METHODS

A subsample of Hispanic/Latino(x), African American/Black, and non-Hispanic White older adults ( N = 1431) from the National Social Life Health and Aging Project was used. Multivariable regression was used to estimate the association between network density and its interaction with race-ethnicity, with hs-CRP 5 years later.

RESULTS

Although no main effect of network density on 5-year hs-CRP was found, results revealed a significant network density by race-ethnicity interaction (Wald χ2 (2, 1242) = 3.31, p = .037). Simple slopes analyses revealed that Hispanic/Latino(x) older adults with high network density had significantly lower hs-CRP levels when compared with their same-ethnic counterparts with low network density ( b = -0.73, standard error = 0.31, 95% confidence interval = -1.33 to -0.13, p = .018).

CONCLUSIONS

Results demonstrate population-level differences in social network structure and differential associations of this infrastructure with health. Implications for the Hispanic Mortality Paradox are discussed.

Associations Between Changes in Loneliness and Social Connections, and Mental Health During the COVID-19 Pandemic: The Women's Health Initiative

BACKGROUND

Older women have faced significant disruptions in social connections during the coronavirus disease 2019 pandemic. Whether loneliness increased or whether a change in loneliness from pre- to intrapandemic period was associated with mental health during the pandemic is unknown.

METHODS

Older women (n = 27 479; mean age 83.2 [SD: 5.4] years) completed surveys in mid-2020, including questions about loneliness, living arrangements, changes in social connections, and mental health. Loneliness was also previously assessed in 2014-2016. We examined whether loneliness changed from the pre- to intrapandemic period and explored factors associated with this change. In multivariable models, we investigated the association of changes in loneliness and social connections with mental health.

RESULTS

Loneliness increased from pre- to intrapandemic levels. Factors associated with worsening loneliness included older age, experiencing stressful life events, bereavement, histories of vascular disease and depression, and social connection disruptions. Factors associated with a decrease in loneliness included identifying as Black, engaging in more frequent physical activity, being optimistic, and having a higher purpose in life. A 3-point increase in loneliness scores was associated with higher perceived stress, higher depressive, and higher anxiety symptoms. Social connection disruptions showed modest or no associations with mental health.

CONCLUSIONS

Loneliness increased during the pandemic in older women and was associated with higher stress, depressive, and anxiety symptoms. Our findings point to opportunities for interventions targeting lifestyle behaviors, well-being, disrupted social connections, and paying closer attention to those with specific medical and mental health histories that may reduce loneliness and improve mental health.

Correlates of psychological distress among adults with obesity during the COVID-19 pandemic

OBJECTIVE

The present study evaluated changes in stress and loneliness among participants with obesity engaged in weight loss self-management in the United States (US) during COVID-19, and identified factors that may increase risk or protect against psychosocial distress during this time.

DESIGN

Participants who were enrolled in a weight self-management program prior to the COVID-19 pandemic (N = 55, 91% female, 36% Caucasian, mean age = 49.8 years) completed an online survey about social, economic and health behaviour changes during COVID-19 and their relationship to changes in perceived stress and loneliness.

MAIN OUTCOME MEASURES

Perceived Stress (PSS-4), Loneliness (PROMIS loneliness and social isolation questionnaire).

RESULTS

Compared to pre-COVID assessments, stress and loneliness increased 40% two months into the COVID-19 pandemic-related shutdown. Higher body mass index (BMI) and social distancing were associated with increases in both loneliness and stress. Alcohol intake was associated with increased stress, and working from home was associated with increased loneliness.

CONCLUSION

Individuals with obesity endorsed increased stress and loneliness during COVID-19, which may be exacerbated among those with a higher BMI and greater adherence to social distancing guidelines. Ongoing attention to psychosocial well-being among individuals with obesity will remain imperative both during the ongoing pandemic and beyond.

The epidemiology of preexisting geriatric and palliative conditions in older adults with poor prognosis cancers

BACKGROUND

Older patients with poor prognosis cancers have complex needs that can benefit from geriatrics and palliative care principles. Because they are not routinely assessed, the prevalence of preexisting geriatric and palliative conditions in this population is unknown.

METHODS

We used the nationally representative Health and Retirement Study (HRS) linked with Medicare claims (1998-2016) to identify adults aged ≥65 years diagnosed with poor prognosis cancers (cancers with a median survival ≤1 year). Using the HRS interview before the first Medicare cancer claim, we used survey-weighted descriptive statistics and modified Poisson regression analysis to examine the prevalence of the following clinically significant conditions: functional impairment, difficulty with mobility, falls and injurious falls, social support, cognition, advance care planning, use of pain or sleep medications, and presence of pain or breathlessness.

RESULTS

Of 2105 participants (mean age 76, 53% women, 34% lung cancer, 21% gastrointestinal cancer), the median survival was 9.6 months. Approximately 65% had difficulty climbing stairs (95% CI 63%-67%), 49% had no advance directive (95% CI 45%-54%), 35% lived alone (95% CI 33%-37%), 36% fell in the last 2 years (95% CI 34%-38%), and 32% rated their memory as poor (95% CI 29%-34%). After adjusting for gender, cancer type, and HRS survey time before the first Medicare claim for a poor prognosis cancer, functional impairment and falls were highest among adults aged 85+. Adults aged 65-74 years were less likely to have an advance directive. After adjusting for age, cancer type, and HRS survey time, women had a higher rate of pain and physical impairment. In exploratory analyses, race and socioeconomic status predicted difficulty with mobility and instrumental activities of daily living, living alone, and advance directive completion.

CONCLUSIONS

Due to a high prevalence across multiple domains, all older adults with poor prognosis cancers should be assessed for geriatric and palliative care conditions.

Social isolation in Asian Americans: risks associated with socio-demographic, health, and immigration factors

OBJECTIVES

The present study examined the factors associated with social isolation in Asian Americans. Three types of social isolation (social isolation from family, social isolation from friends, and overall social isolation), identified by the Lubben Social Network Scale-6, were examined with a sample of Asian Americans representing diverse ethnic groups (Chinese, Asian Indian, Korean, Vietnamese, Filipino, and other Asians) and a broad age range (18-98).

DESIGN

Using data from the 2015 Asian American Quality of Life Survey (N = 2609), logistic regression models examined how each type of social isolation was predicted by sociodemographic (age, gender, ethnic origin, marital status, education, and perceived financial status), health-related (chronic medical conditions and self-rated health), and immigration-related (proportion of life in the United States and English proficiency) variables.

RESULTS

The percentage of the sample that fell into the category of social isolation from family, social isolation from friends, and overall isolation ranged from 18.2% to 19.3%. At 36% in the friend category and 33% in the overall category, the Vietnamese sample showed a heightened risk of social isolation. Regression analyses indicated that, for both family and friend categories, individuals who were in the middle-aged group (40-59 years old) and who had limited English proficiency demonstrated higher odds of being isolated. Reflecting relational differences in family and friend networks, the risk associated with unmarried status was specific to social isolation from family, whereas having unmet financial needs was only associated with social isolation from friends.

CONCLUSIONS

The study findings expand our understanding of the multiple domains of social isolation in an understudied population and emphasize the importance of developing prevention and intervention programs to foster social connectedness among Asian Americans. Our findings on risk factors and ethnic variations help identify the groups to be prioritized in intervention efforts and suggest ways to approach them.

Social isolation and psychological well-being among older Chinese Americans: Does resilience mediate the association?

OBJECTIVES

Social isolation imposes risks to an individual's psychological well-being. However, few studies have examined the role of resilience on these associations among older Chinese Americans, the fastest-growing aging population across all racial/ethnic groups in the United States. We aim to examine the associations of social isolation with indicators of psychological well-being and the mediating role of resilience in these associations.

METHODS

Data were derived from 398 Chinese older adults aged over 55 residing in Honolulu, Hawaii, in 2018. Psychological well-being was measured by psychological distress, life satisfaction, and happiness. Multivariate linear regressions and ordered logistic regressions were conducted.

RESULTS

Social isolation was positively associated with psychological distress and negatively associated with life satisfaction and happiness (all p < 0.05). By contrast, resilience was associated with lower levels of psychological distress and higher levels of life satisfaction and happiness (all p < 0.05). Moreover, the findings supported our hypothesis that resilience mediated the association between social isolation and psychological well-being. With regard to social isolation, resilience contributed to 32.0% of its association with distress, 24.9% of the association with life satisfaction, and 16.3% of the association with happiness.

CONCLUSION

Our findings revealed a significant association between social isolation and psychological well-being and the mediating role of resilience in the association of older Chinese Americans in Hawaii. The study findings expand our understanding of psychological resources in older Chinese Americans and emphasize the importance of developing intervention programs to foster social connection and resilience among an understudied population.

A systematic review of loneliness and social isolation among Hispanic/Latinx older adults in the United States

Loneliness and social isolation are growing public health problems in older adults, associated with physical and mental comorbidity and increased mortality. In the United States, Hispanic/Latinx individuals constitute the largest racial/ethnic minority. Studies retrieved from PsycInfo, Embase, and PubMed were examined. The initial search yielded 1476 publications. Using the updated PRISMA Flow guidelines, a total of 17 studies met our review criteria. Eight studies assessed loneliness, six evaluated social isolation, and three investigated both. The reports varied in the details of methodology, preventing meta-analyses. Differences in the experience of loneliness and social isolation between Hispanic/Latinx and White adults are not consistent. Of the three studies of loneliness or social isolation among Hispanic/Latinx groups of different national origins, two reported significant differences. Loneliness was associated with greater overall comorbidity, but two studies found higher risk of metabolic and cardiovascular disorders in Hispanic/Latinx with loneliness. Social isolation was generally associated with worse physical health, being older, male, and unmarried, and having lower education and income, and more smoking, along with frailty and cognitive impairment. We make specific suggestions for future research on loneliness and social isolation in Hispanic/Latinx adults and offer guidelines for clinical management.

Social isolation among older veterans: findings from the National Health and Aging Trends Study

OBJECTIVES

Social isolation is a critical public health issue that affects multiple domains of well-being among older adults, but little is known about social isolation among older military veterans. As such, the purpose of this study was to estimate the prevalence of social isolation among older veterans and to examine risk factors for social isolation among older veterans.

METHOD

Data were derived from Round 1 of the National Health and Aging Trends Study, which is an annual, longitudinal panel survey of Medicare beneficiaries aged 65 and older. The sample included 1,683 veterans, who were primarily White and male. Weighted logistic regression models were used to predict severe social isolation (having no social participation) and social isolation (having only one source of social participation) among older veterans, while controlling for age, sex, race, marital status, education, income, and metropolitan residency.

RESULTS

After accounting for other predictors, results show that veterans who are 85 and older, male, White, unmarried or unpartnered, with lower educational attainment and lower income are greatly at risk of both severe social isolation and social isolation.

CONCLUSION

The results of this study support past research showing that veterans with limited social and economic capital are at great risk of experiencing adverse outcomes in older adulthood, including social isolation. Interventions should therefore aim to improve social connectedness among this population and should address the risk-factors that contribute to social isolation among older veterans.

Persistence, Impairment, Disability and Unmet Treatment of Lifetime and 12-Month Anxiety Disorders in Black Men and Women, 50 Years of Age and Older

Objectives: To examine anxiety disorders in aging Black adults. Methods: Using nationally representative data from the National Survey of American Life, we estimated lifetime/12-month prevalence of anxiety disorders in Black men and women, age 50+ (N = 1561). Disorder-specific persistence and severity, functional impairment, and mental health service utilization were investigated using multivariate regressions. Results: Black men and women who met criteria for anxiety disorders (lifetime prevalence=12.4%/18.3% in men/women) also demonstrated persistent disorders (percent meeting criteria = 40.3%-61.2%). Those with a 12-month anxiety disorder (6.2%/10.5% of men/women) typically reported severe task interference (38.3%-85.7%). Those with any 12-month anxiety disorder, compared to those without, experienced greater impairment in days out of role, work, family burden, cognition and, in women, mobility (p's < .05). Only 47.0%/65.2% of Black men/women with any lifetime anxiety disorder used mental health services. Discussion: Despite low prevalence, older Blacks with anxiety disorders experience substantial mental health burden in middle age and later.

Loneliness as a Mediator in the Association Between Social Isolation and Psychological Distress: A Cross-Sectional Study With Older Korean Immigrants in the United States

The present study explored the role of loneliness in the association between social isolation and psychological distress, using a cross-sectional sample of older Korean immigrants in the U.S. Considering structural (unmarried and living alone) and relational (isolation from family and friends) social isolation, we hypothesized that (1) both types of social isolation would be associated with loneliness and psychological distress and (2) their effect on psychological distress would be mediated through loneliness. Data came from the Study of Older Korean Americans (SOKA), a multisite survey of Korean immigrants aged 60 and older (n = 2,150). The multivariate analyses demonstrated that older individuals with structural and relational isolation reported higher levels of loneliness and psychological distress. Loneliness was found to mediate the effect of both types of social isolation on psychological distress. The intervening role of loneliness suggests strategies to alleviate the mental health consequences of social isolation in older immigrants.

Assessing the Validity of Self-rated Health Across Ethnic Groups: Implications for Health Disparities Research

OBJECTIVES

This study examines the association between morbidity (i.e., chronic health conditions) and self-rated health (SRH) with the aim of testing the within-group and across-group validity of SRH across nine ethnic groups: non-Latinx White, Mexican, Puerto Rican, Cuban, African American, Afro-Caribbean, Chinese, Filipino, and Vietnamese Americans. In addition, we assess whether acculturation (i.e., nativity, years of US residency, language of interview) and health-related factors (e.g., mental disorder) account for ethnic distinctions in SRH.

DESIGN

Data are from the National Survey of American Life (NSAL) and the National Latino and Asian American Study (NLAAS) (N = 8338). Weighted proportions and means for SRH and chronic conditions are reported. Ordered logistic regression analysis is used to determine ethnic group patterns in SRH.

RESULTS

Despite evidence of within-group validity of SRH for each ethnic group, our results seriously challenge the across-group validity of SRH. For example, Chinese and Vietnamese respondents report lower SRH despite having fewer chronic conditions relative to non-Latinx Whites. Moreover, Mexican Americans report fewer chronic health problems but lower SRH compared to non-Latinx Whites. Acculturation factors (e.g., language of interview) partially explain the Mexican-White difference in SRH. Among Chinese Americans, completing an interview in English is associated with higher SRH relative to those who completed an interview in Chinese.

CONCLUSION

These findings have implications for health disparities research that uses SRH as the dependent measure. Studies that compare the health profiles of diverse ethnic groups should use the SRH measure with caution, as SRH does not align with ethnic patterns of morbidity.

Loneliness, sadness, and feelings of social disconnection in older adults during the COVID-19 pandemic

BACKGROUND

Public health measures to control the COVID-19 pandemic have led to feelings of loneliness among older adults, which, prior to COVID, has been associated with subsequent morbidity and mortality. We sought to identify differences in feelings of loneliness, sadness, and social disconnection early in the pandemic across racial groups, and possible mitigating factors.

METHODS

We performed a cross-sectional analysis using the weighted nationally-representative Medicare Current Beneficiaries Survey COVID-19 supplement, collected summer 2020. We included all Medicare beneficiaries aged 65 years and older who did not respond by proxy. We examined changes in loneliness, sadness, or feelings of social disconnection. Multivariable logistic regression models accounted for sociodemographic variables, access to primary care and the internet, and history of depression or dementia.

RESULTS

Among 8125 beneficiaries, representative of 43.7 million Medicare beneficiaries, 22.6% reported loneliness or sadness, and 37.1% feeling socially disconnected. In fully-adjusted models, Hispanic/Latinx beneficiaries were most likely to report loneliness or sadness (OR = 1.3, CI: 1.02-1.65; p = 0.02) and Black beneficiaries were least likely to report feeling socially disconnected (OR = 0.55; CI: 0.42-0.73; p < 0.001). Internet access was associated with increased odds of both (OR = 1.29, 95 CI: 1.07-1.56; p = 0.009; and OR = 1.42, 95 CI: 1.24-1.63; p < 0.001, respectively). Access to primary care was associated with lower odds of both (OR = 0.77, 95 CI: 0.61-0.96; p = 0.02; and OR = 0.72, 95 CI: 0.61-0.87; p < 0.001).

CONCLUSIONS

Loneliness, sadness, and feelings of social disconnection were common among older Medicare beneficiaries early in the COVID-19 pandemic. Differences by race/ethnicity may be driven by different living structures and social networks, and warrant further study. Policy makers and clinicians should consider facilitating connection by phone or in person, as internet access did not diminish feelings of loneliness, particularly for those living alone. Access to primary care, and tools for clinicians to address loneliness should be prioritized.

Examining Rural and Racial Disparities in the Relationship Between Loneliness and Social Technology Use Among Older Adults

Loneliness, the subjective negative experience derived from a lack of meaningful companionship, is associated with heightened vulnerability to adverse health outcomes among older adults. Social technology affords an opportunity to cultivate social connectedness and mitigate loneliness. However, research examining potential inequalities in loneliness is limited. This study investigates racial and rural-urban differences in the relationship between social technology use and loneliness in adults aged 50 and older using data from the 2016 wave of the Health and Retirement Study (N = 4,315). Social technology use was operationalized as the self-reported frequency of communication through Skype, Facebook, or other social media with family and friends. Loneliness was assessed using the UCLA Loneliness scale, and rural-urban differences were based on Beale rural-urban continuum codes. Examinations of race focused on differences between Black/African-American and White/Caucasian groups. A path model analysis was performed to assess whether race and rurality moderated the relationship between social technology use and loneliness, adjusting for living arrangements, age, general computer usage. Social engagement and frequency of social contact with family and friends were included as mediators. The primary study results demonstrated that the association between social technology use and loneliness differed by rurality, but not race. Rural older adults who use social technology less frequently experience greater loneliness than urban older adults. This relationship between social technology and loneliness was mediated by social engagement and frequency of social contact. Furthermore, racial and rural-urban differences in social technology use demonstrated that social technology use is less prevalent among rural older adults than urban and suburban-dwelling older adults; no such racial differences were observed. However, Black older adults report greater levels of perceived social negativity in their relationships compared to White older adults. Interventions seeking to address loneliness using social technology should consider rural and racial disparities.

Loneliness During the COVID-19 Pandemic Among Older Adults With Chronic Conditions

The COVID-19 pandemic may intensify loneliness among older adults with chronic conditions who are at high risk of severe illness, but little is known about factors associated with loneliness during the pandemic. We considered factors linked to loneliness among 701 adults aged 50 years and older with chronic conditions from Michigan (82.5%) and 33 other U.S. states. Participants completed an anonymous online survey between May 14 and July 9, 2020. About two thirds (66.4%) reported moderate to severe loneliness. The fully adjusted regression model revealed that being a person of color, having a spouse or cohabiting partner, and more emotional support were associated with lower levels of loneliness. Higher anxiety symptoms, more worry about COVID-19 infection, and more financial strain because of the pandemic were linked to greater loneliness. These findings inform strategies to support a vulnerable subgroup of older adults during this pandemic and in future public health crises.

Neighborhood Social Group Participation and Depressive Symptoms Among Mid-to-Late Life Black Americans: Does the Association Differ by Ethnicity?

This study examined how neighborhood social participation relates to depressive symptoms among middle-aged and older African Americans and Caribbean Blacks. A subsample of African Americans (N = 1616) and Caribbean Blacks (N = 601) age 40 and older were drawn from the National Survey of American Life (NSAL). Ordinary least squares (OLS) regression was used to examine the association between neighborhood social participation and depressive symptoms. In fully adjusted models, non-participation in available neighborhood organizations was associated with higher depressive symptoms among Caribbean Blacks (b = 1.93, p < .01), while neighborhood social participation was unrelated to depressive symptoms among African Americans. Non-participation in available neighborhood group associations is a risk factor for depressive symptoms among middle-aged and older Caribbean Blacks. Future research should assess the correlates of non-participation in available neighborhood organizations, and the mechanisms underlying how non-participation in these organizations relates to the psychological well-being of Caribbean Blacks.

Exacerbating Inequalities: Social Networks, Racial/Ethnic Disparities, and the COVID-19 Pandemic in the United States

OBJECTIVES

The disruption and contraction of older adults' social networks are among the less discussed consequences of the COVID-19 pandemic. Our objective was to provide an evidence-based commentary on racial/ethnic disparities in social network resources and draw attention to the ways in which disasters differentially affect social networks, with meaningful insight for the ongoing pandemic.

METHODS

We draw upon prior research on social networks and past natural disasters to identify major areas of network inequality. Attention is given to how pre-pandemic racial/ethnic network disparities are exacerbated during the current crisis, with implications for physical and mental health outcomes.

RESULTS

Evidence from the literature shows a robust association between strong social networks and physical and mental health outcomes. During times of crisis, access to social networks for older adults is disrupted, particularly for marginalized groups. We document pre-pandemic disparities in social networks resources and offer insight for examining the impact of COVID-19 on disrupting social networks among older adults.

DISCUSSION

Importantly, racial/ethnic disparities in social networks both prior to and as a result of the pandemic intensify existing inequalities and demonstrate the necessity of better understanding social network inequalities for marginalized older adults, particularly in the context of the COVID-19 health crisis.

Older Black Americans During COVID-19: Race and Age Double Jeopardy

The concept of "double jeopardy"-being both older and Black-describes how racism and ageism together shape higher risks for coronavirus exposure, COVID-19 disease, and poor health outcomes for older Black adults. Black people and older adults are the two groups most affected by COVID-19 morbidity and mortality. Double jeopardy, as a race- and age-informed analysis, demonstrates how Black race and older age are associated with practices and policies that shape key life circumstances (e.g., racial residential segregation, family and household composition) and resources in ways that embody elevated risk for COVID-19. The concept of double jeopardy underscores long-standing race- and age-based inequities and social vulnerabilities that produce devastating COVID-19 related deaths and injuries for older Black adults. Developing policies and actions that address race- and age-based inequities and social vulnerabilities can lower risks and enhance protective factors to ensure the health of older Black Americans during the COVID-19 pandemic.

Culturally Responsive Health Promotion to Address Health Disparities in African American Men: A Program Impact Evaluation

African American (AA) men continue to experience worse health outcomes compared to men of other races/ethnicities. Community-based interventions are known to be effective in health promotion and disease prevention. The program objectives were to (a) increase knowledge and risk awareness of targeted conditions, (b) change health-care-seeking attitudes toward regular primary care among AA men, and (c) improve their lifestyle-related health behaviors by leveraging the influence of women in their lives. The community-engaged educational intervention targeted both men and women and included eight 90-min sessions per cohort. Topics included prostate cancer, cardiovascular disease, diabetes, mental health, health-care access, and healthy lifestyle. Sessions were both didactic and interactive. A pre-/post-intervention questionnaire assessed knowledge. Interviews were conducted with male participants and a focus group discussion (FGD) with women to assess program impact. Interview and FGD transcripts were analyzed for themes and recommendations. Major themes were-increased knowledge/awareness of risk associated with chronic conditions, change in health-care-seeking attitudes, increased self-efficacy to engage the health-care system, and lifestyle changes. Other impacts reported were building community/social support, a safe and enabling learning environment, and enhanced community health status overall. Recommendations included having extended, more in-depth sessions, targeting the younger generation, smaller cohort sizes, and more community-based health programming. Community-engaged health promotion using a cohort model as well as including women can be effective in increasing knowledge, enhancing self-efficacy, and providing the much-needed social support. These can influence health-related behaviors and thus contribute to improving health outcomes for AA men.

Social Isolation's Influence on Loneliness among Older Adults

Social isolation and loneliness are significant risks to health among older adults. Previous studies have found a significant association between social isolation and loneliness; however, few studies examined the association between social isolation and loneliness in a multivariate context and how specific types of social isolation influence loneliness. This study fills this gap by examining social isolation's overall influence on loneliness and how specific social isolation indicators influence loneliness. Data comes from 2014 Wave of the Health and Retirement Study, a nationally representative study of adults aged 50 and older. Social isolation was operationalized using seven indicators as social isolation from: 1) adult children, 2) other family members, 3) friends, 4) living alone, 5) being unmarried, and 6) not participating in social groups or 7) religious activities. Loneliness was operationalized by the Hughes 3-item loneliness scale. Loneliness was regressed on social isolation and key socio-demographic factors. Results found when social isolation indicators were combined into an index, every unit increase in overall social isolation was associated with an increase in loneliness. Furthermore older adults who were isolated from other family members and from friends, lived alone, were single, and did not participate in social groups or religious activities reported greater loneliness. Study findings demonstrate that greater overall social isolation and specific social isolation indicators are associated with greater loneliness. Clinical practice with older adults can be enhanced by understanding the connections between social isolation and loneliness and which forms of social isolation are more meaningful for perceived loneliness.

Driving Cessation and Social Isolation in Older Adults

Objective: This study investigated the impact of driving cessation on social isolation in older adults. Method: Data were obtained from Rounds 1 through 6 of the National Health and Aging Trends Study. The study sample consisted of 6,916 Medicare beneficiaries aged 65 or above who were eligible drivers at baseline. Mixed-effects ordered logistic regression and piecewise regression were used to examine the impact of driving cessation on social isolation. Results: In multivariable mixed-effects ordered logistic regression, past-year nondrivers had a twofold increase in the odds of being in a higher social isolation category (odds ratio [OR] = 2.1, p < .001). Piecewise regression analysis showed that social isolation scores increased by 0.08 points (p = .024) following an incident of driving cessation. Discussion: Driving cessation is associated with a higher risk of social isolation in older adults. Interventions to reduce social isolation among older adults may improve public health by targeting older adults who have recently stopped driving.

Obesity and Polypharmacy among African American Older Adults: Gender as the Moderator and Multimorbidity as the Mediator

Despite high prevalence of obesity and polypharmacy among African American (AA) older adults, little information exists on the associations between the two in this population. This study explored the association between obesity and polypharmacy among AA older adults who were residing in poor urban areas of South Los Angeles. We also investigated role of gender as the moderator and multimorbidity as the mediator of this association. In a community-based study in South Los Angeles, 308 AA older adults (age ≥ 55 years) were entered into this study. From this number, 112 (36.4%) were AA men and 196 (63.6%) were AA women. Polypharmacy (taking 5+ medications) was the dependent variable, obesity was the independent variable, gender was the moderator, and multimorbidity (number of chronic medical conditions) was the mediator. Age, educational attainment, financial difficulty (difficulty paying bills, etc.), income, marital status, self-rated health (SRH), and depression were the covariates. Logistic regressions were used for data analyses. In the absence of multimorbidity in the model, obesity was associated with higher odds of polypharmacy in the pooled sample. This association was not significant when we controlled for multimorbidity, suggesting that multimorbidity mediates the obesity-polypharmacy link. We found significant association between obesity and polypharmacy in AA women not AA men, suggesting that gender moderates such association. AA older women with obesity are at a higher risk of polypharmacy, an association which is mainly due to multimorbidity. There is a need for screening for inappropriate polypharmacy in AA older women with obesity and associated multimorbidity.
