Hearing and vision impairment and social isolation over 8 years in community-dwelling older adults.

BACKGROUND: Little is known about the long-term impact of hearing and vision impairment on social isolation. This study quantifies the association between hearing, vision, and concurrent hearing and vision impairment (dual sensory impairment) and social isolation over 8 years among older adults. METHODS: Data were from the National Health and Aging Trends Study (NHATS), a cohort study (2011 - 2019) of U.S. Medicare beneficiaries aged 65 years and older. Social isolation was measured by a binary indicator incorporating four domains: living arrangement, core discussion network size, religious attendance, and social participation. Hearing, vision, and dual sensory impairments were measured by self-report and modeled categorically (no impairment [ref.], hearing impairment only, vision impairment only, dual sensory impairment). Associations between sensory impairments and odds of social isolation over 8 years were assessed using multivariate generalized logistic mixed models and adjusted for demographic and health characteristics. RESULTS: Among 5,552 participants, 18.9% self-reported hearing impairment, 4.8% self-reported vision impairment, and 2.3% self-reported dual sensory impairment. Over 8 years, hearing impairment only was associated with 28% greater odds of social isolation. Participants with hearing impairment only were more likely to live alone and have limited social participation. CONCLUSION: Greater clinical awareness of hearing impairment as a risk factor for social isolation can increase opportunities to identify and aid older adults who may benefit from resources and interventions to increase social connection and mitigate social isolation.

Association of Social Isolation With Hospitalization and Nursing Home Entry Among Community-Dwelling Older Adults.

Importance: Social isolation is associated with adverse health outcomes, yet its implications for hospitalization and nursing home entry are not well understood. Objective: To evaluate whether higher levels of social isolation are associated with overnight hospitalization, skilled nursing facility stays, and nursing home placement among a nationally representative sample of community-dwelling older adults after adjusting for key health and social characteristics, including loneliness and depressive symptoms. Design, Setting, and Participants: This observational cohort study included 7 waves of longitudinal panel data from the Health and Retirement Study, with community-dwelling adults aged 65 years or older interviewed between March 1, 2006, and June 30, 2018 (11 517 respondents; 21 294 person-years). Data were analyzed from May 25, 2022, to May 4, 2023. Main Outcomes and Measures: Social isolation was measured with a multidomain 6-item scale (range, 0-6, in which a higher score indicates greater isolation). Multivariate logistic regressions were performed on survey-weighted data to produce national estimates for the odds of self-reported hospitalization, skilled nursing facility stays, and nursing home placement over time. Results: A total of 57% of this study's 11 517 participants were female, 43% were male, 8.4% were Black, 6.7% were Hispanic or Latino, 88.1% were White, 3.5% were other ("other" includes American Indian or Alaska Native, Asian or Pacific Islander, and other race, which has no further breakdown available because this variable was obtained directly from the Health and Retirement Study), and 58.2% were aged 65 to 74 years. Approximately 15% of community-dwelling older adults in the US experienced social isolation. Higher social isolation scores were significantly associated with increased odds of nursing home placement (odds ratio, 2.01; 95% CI, 1.21-3.32) and skilled nursing facility stays (odds ratio, 1.16; 95% CI, 1.06-1.28) during 2 years. With each point increase in an individual's social isolation score, the estimated probability of nursing home placement or a skilled nursing facility stay increased by 0.5 and 0.4 percentage points, respectively, during 2 years. Higher levels of social isolation were not associated with 2-year hospitalization rates. Conclusions and Relevance: This cohort study found that social isolation was a significant risk factor for nursing home use among older adults. Efforts to deter or delay nursing home entry should seek to enhance social contact at home or in community settings. The design and assessment of interventions that optimize the social connections of older adults have the potential to improve their health trajectories and outcomes.

Examining the Association of Social Isolation and Smoking in Older Adults.

Background: Tobacco use remains a leading cause of preventable death among older adults, but few studies have examined social isolation as a risk factor for smoking in US. older adults. Methods: Using National Health and Aging Trends Study (NHATS) data, we conducted multivariate analyses of smoking in a sample of 8136 adults ages 65 and older. Results: Social isolation and severe isolation were associated with higher odds of smoking (OR: 2.48 and 5.48, p = 0.002 and p < 0.001). Individuals with mild (OR: 1.46, p = 0.006), moderate (OR: 1.80, p = 0.001), or severe (OR: 3.05, p = 0.001) symptoms of depression/anxiety also had higher odds of smoking. Conclusions: Social isolation is a significant risk factor for smoking in US older adults. Further research is needed to support the development of interventions to reduce social isolation and smoking behavior in older adults.

Social isolation and 9-year dementia risk in community-dwelling Medicare beneficiaries in the United States.

BACKGROUND: Social isolation can influence whether older adults develop dementia. We examine the association between social isolation and incident dementia among older adults in a nationally representative sample of community dwelling older adults in the United States (U.S.). We also investigate whether this association varies by race and ethnicity. METHODS: Data (N = 5022) come from the National Health and Aging Trends Study, a longitudinal and nationally representative cohort of older adults in the U.S. A composite measure of social isolation was used to classify older adults as socially isolated or not socially isolated at baseline. Demographic and health factors were measured at baseline via self-report. Dementia was measured at each round of data collection. Discrete-time proportional hazard time-to-event models were used to assess the association between social isolation and incident dementia over 9 years (2011-2020). RESULTS: Of 5022 older adults, 1172 (23.3%) were socially isolated, and 3850 (76.7%) were not socially isolated. Adjusting for demographic and health factors, being socially isolated (vs. not socially isolated) was associated with a 1.28 (95% CI: 1.10-1.49) higher hazard of incident dementia over 9 years. There was no statistically significant difference by race and ethnicity. CONCLUSION: Social isolation among older adults is associated with greater dementia risk. Elucidating the pathway by which social isolation impacts dementia may offer meaningful insights for the development of novel solutions to prevent or ameliorate dementia across diverse racial and ethnic groups.

Impact of technology on social isolation: Longitudinal analysis from the National Health Aging Trends Study.

BACKGROUND: Social isolation is a key public health concern and has been associated with numerous negative health consequences. Technology is increasingly thought of as a solution to address social isolation. This study examines the longitudinal association between the access and use of technology and social isolation in older adults 65 and older, living in the United States. METHODS: This observational cohort study included community-dwelling older adults (N = 6704) who participated in the National Health and Aging Trends Study. Regression analyses were conducted using data from 2015 to 2019. Information about technology access and use was ascertained using self-reported questionnaires. The primary outcome was the risk of social isolation. RESULTS: At baseline, the majority of older adults that were not socially isolated had a working cell phone (88%) or computer (71%) and used email or text messaging (56%). Older adults that had access to (cell phone- incidence rate ratio [IRR] 0.62 [95% CI 0.48-0.81]; computer- IRR 0.63 [95% CI 0.51-0.78]), and used technology (email or text messaging- IRR 0.64 [95% CI 0.51-0.80]) in the year prior had a lower risk of social isolation than older adults who reported they did not access or use technology. Additionally, over four years, older adults who reported that they had access to a computer had a lower risk (0.69 [0.57, 0.84]) for social isolation than their counterparts. CONCLUSION: In this cohort study, technology access was associated with a lower risk for social isolation among community-dwelling older adults. These findings suggest that technology has an important role in approaches that seek to prevent social isolation among older adults.

Prevalence of Mental Health and Social Connection among Patients Seeking Tobacco Dependence Management: A Pilot Study.

INTRODUCTION: with regards to tobacco dependence management, there are certain barriers to successful smoking cessation for patients, such as untreated anxiety and depression. Complicating the impact of mental health morbidities on tobacco dependence may be the significant portion of patients whose mental health issues and limited social connections are undiagnosed and unaddressed. We hypothesize that patients with no prior mental health diagnoses who are treated for tobacco dependence have high rates of undiagnosed mental health morbidities. METHODS: patients were recruited from a tobacco treatment clinic in 2021. Every patient who came for an inaugural visit without a prior diagnosis of mental health disease was screened for depression, anxiety, social isolation and loneliness. Sociodemographic variables were collected. RESULTS: over a 12-month period, 114 patients were seen at the tobacco treatment clinic. Of these 114 patients, 77 (67.5%) did not have a prior diagnosis of a mental health disease. The mean age was 54.3 ± 11.2 years, 52 (67.5%) were females, and 64 (83.1%) were Black/African American. The mean age of starting smoking was 19.3 ± 5.2 years, and 43 (55.8%) had never attempted to quit smoking in the past. With regards to mental health screening, 32 (41.6%) patients had a score of 9 or greater on the Patient Health Questionnaire (PHQ) 9, 59 (76.6%) had a score of 7 or greater on the Generalized Anxiety Disorder (GAD) 7, 67 (87.0%) were identified with social isolation and 70 (90.1%) for loneliness on screening. CONCLUSION: there was a high prevalence of undiagnosed mental health morbidities and social disconnection in patients who were actively smoking and were struggling to achieve smoking cessation. While a larger scale study is necessary to reaffirm these results, screening for mental health morbidities and social disconnection may be warranted in order to provide effective tobacco dependence management.

The effect of COVID-19 pandemic-related financial challenges on mental health and well-being among US older adults.

BACKGROUND: Despite profound financial challenges during the COVID-19 pandemic, there is a gap in estimating their effects on mental health and well-being among older adults. METHODS: The National Health and Aging Trends Study is an ongoing nationally representative cohort study of US older adults. Outcomes included mental health related to COVID-19 (scores averaged across eight items ranging from one to four), sleep quality during COVID-19, loneliness during COVID-19, having time to yourself during COVID-19, and hopefulness during COVID-19. Exposures included income decline during COVID-19 and financial difficulty due to COVID-19. Propensity score weighting produced covariate balance for demographic, socioeconomic, household, health, and well-being characteristics that preceded the pandemic to estimate the average treatment effect. Sampling weights accounted for study design and non-response. RESULTS: In weighted and adjusted analyses (n = 3257), both income decline during COVID-19 and financial difficulty due to COVID-19 were associated with poorer mental health related to COVID-19 (b = -0.159, p < 0.001 and b = -0.381, p < 0.001, respectively), poorer quality sleep (OR = 0.63, 95% CI: 0.46, 0.86 and OR = 0.42, 95% CI: 0.30, 0.58, respectively), more loneliness (OR = 1.53, 95% CI: 1.16, 2.02 and OR = 2.72, 95% CI: 1.96, 3.77, respectively), and less time to yourself (OR = 0.54, 95% CI: 0.40, 0.72 and OR = 0.37, 95% CI: 0.27, 0.51, respectively) during COVID-19. CONCLUSIONS: Pandemic-related financial challenges are associated with worse mental health and well-being regardless of pre-pandemic characteristics, suggesting that they are distinct social determinants of health for older adults. Timely intervention is needed to support older adults experiencing pandemic-related financial challenges.

Social isolation, homebound status, and race among older adults: Findings from the National Health and Aging Trends Study (2011-2019).

BACKGROUND: Multiple factors may influence the risk of being homebound, including social isolation and race. This study examines the relationship between social isolation and homebound status by race over 9 years in a sample of adults. METHODS: Utilizing a representative sample of 7788 Medicare beneficiaries aged 65+ from 2011-2019, we assessed the odds of becoming homebound by social isolation. We defined social isolation as the objective lack of contact with others. We defined severe social isolation as scoring a 0 or 1 on a social connection scale from 0 to 4. Homebound status was defined as never leaving home or only leaving home with difficulty. Utilizing a multivariate Cox proportional hazards model adjusting for age, gender, marital status, income, and education, we examined the association between social isolation at baseline and becoming homebound during the study in those who were not initially homebound. RESULTS: Older adults in this study were on average 78 years old. Overall, most were white (69%), female (56.3%), and married (57.8%) and reported that they had a college education or higher (43.9%). Also, at baseline, approximately 25% of study participants were socially isolated, 21% were homebound, and 6.3% were homebound and socially isolated or severely socially isolated. Homebound status at baseline varied by race: Black, 23.9% and white, 16.6% (p < 0.0001). After 9 years, socially isolated black (hazard risk ratio, HRR 1.35, 95% confidence interval CI [1.05,1.73], p < 0.05) and white (HRR 1.25, 95% CI [1.09,1.42], p < 0.01) older adults were at higher risk of becoming homebound. CONCLUSION: Socially isolated black and white adults are more likely to be homebound at baseline and become homebound over time. Further research is needed to determine whether community-based strategies and policies that identify and address social isolation reduce homebound status among community-dwelling older adults.

SARS-CoV-2 in assisted living: Mortality and asymptomatic infection.

In response to a rapid rise in mortality within assisted living, facility-wide resident testing found 42% of 182 residents had SARS-CoV-2 infection; 68% of which were asymptomatic for 14 days before and after testing. Resident testing was a critical infection control measure needed to control transmission of SARS-CoV-2 infection.

Getting under the skin: Social isolation and biological markers in the National Health and Aging Trends Study.

BACKGROUND: Social isolation is a risk factor for morbidity and mortality comparable to well-established risk factors including smoking, hypertension, and a sedentary lifestyle. The specific biological mechanisms that connect social isolation to morbidity and mortality remain unclear. Interleukin-6 (IL-6) and C-reactive protein (CRP) are biological markers that are upregulated during inflammation and can have long-term negative consequences for the health of individuals as they age. METHODS: Utilizing Round 7 (2017) data from the National Health and Aging Trends Study (NHATS), we examine the relationship between social isolation and two biological markers: IL-6 and high-sensitivity CRP. This study included a nationally representative sample of 4648 Medicare beneficiaries 65 years and older who provided samples using dried blood spot (DBS) techniques. We defined social isolation utilizing a multi-domained typology that considers living arrangement, core discussion network, religious attendance, and social participation. IL-6 and CRP were obtained via DBS that were collected in Round 7 of the NHATS. We performed linear regression to examine the association between social isolation and biological markers IL-6 and CRP. RESULTS: After adjusting for age, gender, race/ethnicity, income, tobacco use, body mass index, and chronic conditions, we found that severe social isolation and social isolation were significantly associated with higher levels of IL-6 and CRP values among older adults. CONCLUSIONS: Social isolation is associated with higher levels of biological markers (IL-6 and CRP). Our findings inform the pathway between social isolation and morbidity and mortality among older adults. IL-6 or CRP could be a proximal outcome measures for future clinical and social interventions that seek to alter the trajectory of social isolation and its associated health outcomes.

Functional Hearing Loss and Social Engagement Among Medicare Beneficiaries.

OBJECTIVES: Hearing loss is common in older adults and limits communication. We investigated the independent association between functional hearing loss and social engagement in a nationally representative sample of older adults. METHODS: Using data from the 2015 Medicare Current Beneficiaries Survey, we modeled the cross-sectional association between self-reported hearing ability and limitation in social activity over the past month using multivariable logistic regression. RESULTS: The majority of the study population was female (54.8%) and non-Hispanic white (74.3%). Participants (40.4%) reported "a little trouble" hearing and 7.4% reported "a lot of trouble" hearing. Those who reported any trouble hearing had higher odds of limited social engagement in the past month. After adjustment for demographic, clinical, and functional covariates, those who reported "a lot of trouble" hearing had 37% higher odds of limited social activity in the past month compared to those with normal hearing. DISCUSSION: These results suggest that hearing loss may be an important risk factor for limited social engagement and downstream negative health consequences, independent of other disability and health conditions.

Second Victims: Aftermath of Gun Violence and Faith-Based Responses.

In the aftermath of gun violence, those impacted and left to mourn are regarded as second victims. These individuals experience and are often burdened by mental and physical sequelae while attempting to cope with the trauma. The objective of this report is to highlight the support and resources of congregational and faith-based leaders available in an urban city with a high prevalence of gun violence. We describe information and insights presented during a symposium uniting medical-religious partners to discuss actions and programs to address trauma from gun violence. Faith-based persons from various Abrahamic religions, ranging from imams to reverends to hospital-based chaplains, discussed key strategies to allocate resources to second victims. These strategies included religious rituals meant to cope with trauma, memorials, and providing insight into resiliency for difficult times. Resources were identified for both within the hospital and community. Such medical-religious resources should be considered for future interventions which aim to attenuate the consequences of gun violence for second victims.
