“…Social isolation is associated with negative health outcomes, especially for Black and Latino older adults. A new study from Johns Hopkins University found that social isolation increases the risk for developing dementia among older adults [ 11 ]. Among older adults, Black people, Latino people, and people with fewer years of education experience more loneliness, leading to higher levels of stress, poor cardiovascular health, depressive symptoms, and cognitive decline, among many other conditions [ 6 ].…”

The United States population is living longer and healthier than ever. This enables our communities—and our society—to continue to benefit from our knowledge, experience, and energy as we age. The public health system is foundational for increasing life expectancy, and now it has the opportunity to further support older adult health and well-being. Trust for America’s Health (TFAH), in partnership with The John A. Hartford Foundation, launched the age-friendly public health systems initiative in 2017 with the goal of raising awareness within the public health sector of its many potential roles in healthy aging. TFAH has worked with state and local departments of health to build capacity and expertise in older adult health and has provided guidance and technical assistance to expand this work across the U.S. TFAH now envisions a public health system that has healthy aging as a core function. This paper aims to describe why the public health sector should adopt healthy aging policies and practices, how this is being operationalized at the state and local levels, and the value of age-friendly public health systems within the age-friendly ecosystem.

“…A review by Majoka and Schimming (2021) explored the literature connecting SDoH factors and ADRD risk and found that higher levels of SES (i.e., household income) were generally associated with reduced risk and longer time to ADRD diagnosis, and that racial discrimination can exacerbate disparities in ADRD risk. Although social isolation is known to increase dementia risk (Huang et al, 2023), social engagement is associated with greater gray matter microstructural integrity, reflecting better brain cellular health, in dementia-prone brain regions (Felix et al, 2021) among older adults.…”

Objective: We examined whether social determinants of health (SDoH) are associated with Alzheimer’s disease and related dementias (ADRD) risk and the effects of cognitive training over a 20-year follow-up period. Methods: Data were obtained from 1605 participants in ACTIVE. SDoH measures were created using baseline data at the individual and neighborhood level. Incident ADRD was defined using administrative claims data (1999–2019). Cause-specific hazard models estimated associations between SDoH and claims-based diagnosed ADRD. Results: Higher scores on neighborhood and built environment were associated with lower ADRD risk. Trained participants obtained a greater degree of protection from ADRD when they had higher scores for SDoH domains associated with health care and education access. However, there were fewer significant SDoH moderation effects on cognitive training than expected. Discussion: Future work should continue to explore culturally tailored cognitive training interventions to reduce ADRD risk associated with SDoH that disproportionately affects racially diverse aging populations.

“…[1] Social isolation can lead to harmful health outcomes (e.g., dementia, depression, and lower quality of life) and can also limit access to health promoting resources (e.g., shared information, emotional support, physical assistance) potentially available through a social support network. [1][2][3][4] In the United States (U.S.), 24% of older adults are socially isolated. [5].…”

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.
