Difficulties with Activities of Daily Living and Receipt of Care Among Older Adults with Cognitive Impairment: Differences Between Those Living Alone and Those Living with Others

Changes in Family Structure and Increasing Care Gaps in the United States, 2015-2050

Research on caregiving in the United States has not clearly identified the scope of the gap between care needed and care received and the changes implied by ongoing and anticipated shifts in family structure. This article examines the magnitude of contemporary gaps in care among older adults in the United States and how they are likely to evolve through 2050. We use data from the Health and Retirement Study (1998-2014) to estimate care gaps, operationalized as having difficulties with activities of daily living (ADLs) or instrumental activities of daily living (IADLs) but not receiving care. We also estimate variation in care gaps by family structure. Then, we use data from demographic microsimulation to explore the implications of demographic and family changes for the evolution of care gaps. We establish that care gaps are common, with 13% and 5% of adults aged 50 or older reporting a care gap for ADLs and IADLs, respectively. Next, we find that adults with neither partners nor children have the highest care gap rates. Last, we project that the number of older adults with care gaps will increase by more than 30% between 2015 and 2050-twice the rate of population growth. These results provide a benchmark for understanding the scope of the potential problem and considering how care gaps can be filled.

Association of Family Support With Lower Modifiable Risk Factors for Dementia Among Cognitively Impaired Older Adults

OBJECTIVES

Cognitive impairment poses considerable challenges among older adults, with the role of family support becoming increasingly crucial. This study examines the association of children's residential proximity and spousal presence with key modifiable risk factors for dementia in cognitively impaired older adults.

METHODS

We analyzed 14,600 individuals (35,165 observations) aged 50 and older with cognitive impairment from the Health and Retirement Study (1995-2018). Family support was categorized by spousal presence and children's residential proximity. Modifiable risk factors, including smoking, depressive symptoms, and social isolation, were assessed. Associations between family support and the modifiable risk factors were determined using mixed-effects logistic regressions.

RESULTS

A significant proportion of older adults with cognitive impairment lacked access to family support, with either no spouse (46.9%) or all children living over 10 miles away (25.3%). Those with less available family support, characterized by distant-residing children and the absence of a spouse, had a significantly higher percentage of smoking, depressive symptoms, and social isolation. Moreover, we revealed a consistent gradient in the percentage of the risk factors by the degree of family support. Relative to older adults with a spouse and co-resident children, those without a spouse and with all children residing further than 10 miles displayed the highest percentage of the risk factors. These findings were robust to various sensitivity analyses.

CONCLUSIONS

Family support from spouses and nearby children serves as a protective factor against modifiable dementia risk factors in cognitively impaired older adults. Policies that strengthen family and social support may benefit this population.

Functional disability and receipt of informal care among Chinese adults living alone with cognitive impairment

BACKGROUND

Adults with cognitive impairment are prone to living alone in large numbers but receive relatively little attention. This study aimed to evaluate whether living alone with cognitive impairment was associated with a higher burden of functional disability but lack of informal care.

METHODS

982 observations of adults living alone with cognitive impairment and 50,695 observations of adults living with others and with normal cognition were identified from 4 waves (2011/2012, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study (CHARLS). A matched comparator was selected using propensity score matching (1:2). Functional disability included disability in Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), and mobility. The time of receiving informal care was measured in monthly hours.

RESULTS

Adults living alone with cognitive impairment demonstrated significantly higher odds ratio of ADL disability (OR = 1.59, 95 % CI: 1.30, 1.95), IADL disability (OR = 1.19, 95 % CI: 1.00, 1.44), mobility disability (OR = 1.38, 95 % CI: 1.12, 1.70), but received fewer hours of informal care (β = -127.7 h per month, standard error = 25.83, P < 0.001), compared to the adults living with others and with normal cognition.

CONCLUSIONS

This study highlights the high burden of functional disability but low coverage of informal care among Chinese adults living alone with cognitive impairment and calls for more resources to be allocated to this vulnerable subpopulation to improve the functional health and to increase the provision of long-term care services.

Proactive Care-Seeking Strategies Among Adults Aging Solo With Early Dementia: A Qualitative Study

OBJECTIVES

People living with dementia need increasing care over time, but 1 in 3 adults with cognitive impairment lives alone. The goal of this study was to explore the self-identified strengths and resources for future care needs of adults aging solo with early dementia.

METHODS

Semistructured interviews with 15 adults not living with a partner and with no children in the same state, who self-identified as having early dementia or mild cognitive impairment; hybrid inductive/deductive reflexive thematic analysis using a successful aging framework.

RESULTS

Participants placed a high value on maintaining independence and expressed concerns about preserving selfhood and becoming a burden to others. These values influenced how participants appraised financial and social resources available to address future care needs and strategies to preempt or respond to needs such as transportation, help with finances, or activities of daily living.

DISCUSSION

Adults without close family are heterogeneous and have variable resources available to address care needs associated with dementia progression. Common values of retaining independence and minimizing burden to others may be helpful in motivating adults aging solo to undertake planning and help-seeking early.

State home and community-based services expenditures and unmet care needs in the United States: Has everyone benefitted equally?

OBJECTIVE

To test whether the impacts of Medicaid's Home and Community-Based Services (HCBS) expenditures have been equitable.

DATA SOURCES AND STUDY SETTING

This is a secondary data analysis. We linked annual data on state-level Medicaid HCBS expenditures with individual data from U.S. Health and Retirement Study (HRS; 2006-2016).

STUDY DESIGN

We evaluated the association between state-level HCBS expenditure quartiles and the risk of experiencing challenges in basic or instrumental activities of daily living (I/ADLs) without assistance (unmet needs for care). We fitted generalized estimating equations (GEE) with a Poisson distribution, log link function, and an unstructured covariance matrix. We controlled demographics, time, and place-based fixed effects and estimated models stratified by race and ethnicity, gender, and urbanicity. We tested the robustness of results with negative controls.

DATA COLLECTION/EXTRACTION METHODS

Our analytic sample included HRS Medicaid beneficiaries, aged 55+, who had difficulty with ≥1 I/ADL (n = 2607 unique respondents contributing 4719 person-wave observations).

PRINCIPAL FINDINGS

Among adults with IADL difficulty, higher quartiles of HCBS expenditure (vs. the lowest quartile) were associated with a lower overall prevalence of unmet needs for care (e.g., Prevalence Ratio [PR], Q4 vs. Q1: 0.91, 95% CI: 0.84-0.98). This protective association was concentrated among non-Hispanic white respondents (Q4 vs. Q1: 0.82, 95% CI: 0.73-0.93); estimates were imprecise for Hispanic individuals and largely null for non-Hispanic Black participants. We found no evidence of heterogeneity by gender or urbanicity. Negative control robustness checks indicated that higher quartiles of HCBS expenditure were not associated with (1) the risk of reporting I/ADL difficulty among 55+ Medicaid beneficiaries, and (2) the risk of unmet care needs among non-Medicaid beneficiaries.

CONCLUSION

The returns to higher state-level HCBS expenditures under Medicaid for older adults with I/ADL disability do not appear to have been equitable by race and ethnicity.

Children's Residential Proximity, Spousal Presence and Modifiable Risk Factors for Dementia among Older Adults with Cognitive Impairment

Background

Cognitive impairment in older adults poses considerable challenges, and the role of family support becomes increasingly crucial. This study aims to examine the impact of children's residential proximity and spousal presence on the key modifiable risk factors for dementia among older adults with cognitive impairment.

Methods

Utilizing the Health and Retirement Study (HRS) data from 1995 to 2018, we analyzed 14,731 participants (35,840 person-waves) aged 50 and older with cognitive impairment. Family support was characterized based on the presence of a spouse and residential proximity to children. Smoking, depressive symptoms and social isolation were included as the key modifiable risk factors for dementia identified in later life. Using mixed-effects logistic regressions, associations between access to family support and the modifiable risk factors were determined, adjusting for various socio-demographic and health-related factors.

Results

Significant associations were found between access to family support and modifiable risk factors for dementia. Cognitively impaired older adults with less available family support, characterized by distant-residing children and the absence of a spouse, had significantly higher risks of smoking, depressive symptoms, and social isolation. Moreover, we revealed a consistent gradient in the prevalence of the risk factors based on the degree of family support. Relative to older adults with a spouse and co-resident children, those without a spouse and with all children residing further than 10 miles displayed the highest risks of smoking, depressive symptoms, and social isolation.

Conclusion

Access to family support, particularly from spouses and proximate children, plays a protective role against key modifiable risk factors for dementia in older adults with cognitive impairment. The findings highlight the need for bolstering family and social support systems to enhance the well-being of this vulnerable population.
