Grandparent Caregiving, Race, and Cognitive Functioning in a Population-Based Sample of Older Adults

Keeping Us Young? Grandchild Caregiving and Older Adults' Cognitive Functioning

Objective

This study investigates longitudinal associations between providing care to grandchildren and cognitive functioning. It also examines heterogeneity in these relationships.

Background

Grandchild caregiving may support older adults' cognitive functioning by providing social engagement and emotional meaning. However, studies caution that time- intensive or custodial grandchild caregiving can take a toll on grandparents. The cognitive health implications of grandchild caregiving may thus depend on contexts including time spent providing care and living arrangements. They may also vary across sociodemographic groups and have greater effects on older adults who are more vulnerable to cognitive decline.

Method

Data came from the 1998-2016 waves of the Health and Retirement Study (HRS) and represented over 11,000 U.S. adults age 50+. Using linear growth curve and dynamic panel models, the analysis explored relationships between level of grandchild care and cognitive functioning over time and across sociodemographic, family, work and health characteristics.

Results

Those providing 100-199, 200-499 or 500+ hours of care to grandchildren had better cognitive functioning than non-caregivers regardless of whether they lived with grandchildren. Positive links between grandchild caregiving and cognition were stronger for lower income, non-working, and unpartnered adults and grew with age and functional limitations.

Conclusion

These findings suggest that providing care to minor grandchildren may help support cognitive functioning as adults age. They also support the hypothesis that more vulnerable or isolated groups of older adults may benefit the most from grandchild caregiving.

A within-subject examination of grandparents' physical activity and sedentary behavior levels in the presence or absence of grandchild care provision

BACKGROUND

This study aimed to examine within-subject differences in levels of physical activity (PA) and sedentary behavior (SB) among Flemish grandparents aged 50 years and older during a day of providing versus not providing grandchild care. Additionally, grandparents' PA and SB levels of the specific caregiving moment within the included care day were also compared with those of the corresponding specific time frame on the matching non-care day.

METHODS

Data were obtained and pooled from three assessment time points of the Healthy Grandparenting Project. Objectively measured PA and SB levels were assessed through ActiGraphs wGT3x(+) worn during waking hours for seven consecutive days and expressed relative to the total wear time of the selected days or moments (i.e., percentage of time per day or per moment). Generalized linear mixed models were used to evaluate the within-subject differences in grandparents' light intensity PA (LIPA), moderate-to-vigorous intensity PA (MVPA) and SB levels between a care and non-care day as well as between the care and non-care moment of those respective days.

RESULTS

A total of 92 grandparents (64.6 ± 4.8 years, 67.4% women) were included in the analyses. During the care day and care moment, grandparents showed higher relative levels of LIPA (∆=4.0% and ∆=7.9%, respectively) and lower relative levels of SB (∆=3.7% and ∆=6.7%, respectively) as compared to their respective non-care day and non-care moment (all p < 0.001). While there was no significant difference in relative MVPA levels between a day of providing versus not providing grandchild care (∆=0.3%, p = 0.500), the grandparents showed significantly lower relative levels of MVPA during the specific care moment against the non-care moment (∆=1.3%, p = 0.029).

CONCLUSIONS

The higher percentage of time of LIPA and lower percentage of time spent on SB during a care day and care moment compared to a non-care day and non-care moment, highlight the positive impact of grandchild care provision on grandparents' activity levels, potentially improving other health-related outcomes. Furthermore, grandparents seem to compensate for their lower MVPA levels during the actual care moment since no differences in MVPA levels were found at day level when compared to a day without grandchild care.

Intergenerational Caregiving Patterns and Cognitive Health among the Sandwich Generation Within Four-Generation Families

This study aims to investigate whether generational differences in intergenerational caregiving patterns (caring for parents only, caring for grandchildren only, and caring for parents and grandchildren simultaneously) are associated with cognitive health disparities among the sandwich generation within four-generation families, drawing upon the theories of intergenerational solidarity and intergenerational stake. Moreover, this study seeks to identify mediators that help explain these disparities. A nationally representative sample of 8,065 respondents was drawn from the 2011 and 2018 waves of the China Health and Retirement Longitudinal Study. The findings reveal that the sandwich generation caring for grandchildren only, as well as those caring for grandchildren and parents simultaneously, exhibit better cognitive health. However, caregiving for parents only is not significantly related to their cognitive health. This study identifies the inability to reduce depressive symptoms as a mediator explaining the insignificant association between caregiving for parents only and the cognitive health of the sandwich generation. The findings underscore the importance of offering support to the sandwich generation within four-generation families to enhance their cognitive health. Moreover, it is imperative to distinguish between different intergenerational caregiving patterns based on generational differences among the sandwich generation, with a specific emphasis on allocating public resources aimed at promoting cognitive health for those engaged in caring for parents.

The mediating role of children's intergenerational support in association between grandparenting and cognitive function among middle-aged and older Chinese: findings from the CHARLS cohort study

OBJECTIVES

With the world's population increasing in age, there has been a significant rise in the prevalence of cognitive impairment and dementia among individuals. This study aims to investigate the association between grandparenting and cognitive function among middle-aged and older Chinese using data from 2011 to 2018 China Health and Retirement Longitudinal Study (CHARLS). Additionally, the study seeks to explore the potential mediating effect of intergenerational support from children on this relationship, using data from the CHARLS 2011 database.

METHODS

5254 participants were recruited at the baseline survey in CHARLS 2011. Subsequently, a follow-up survey was conducted over 8 years, from CHARLS 2011 to 2018, with 1472 individuals completing the follow-up survey. The CHARLS included surveys on grandparenting and cognitive assessments. Grandparenting was categorized as yes and no. The assessment of cognitive function involved the evaluation of episodic memory and mental intactness. The present study used cross-sectional and longitudinal analyses to examine the relationship between grandparenting and cognitive function. The bootstrap method assessed the mediating effect of children's intergenerational support.

RESULTS

The results of both cross-sectional and longitudinal studies indicated a positive association between grandparenting and cognitive function in middle-aged and older Chinese (B = 0.138, p < 0.05; B = 0.218, p < 0.05). Children's emotional and economic support played intermediary roles between grandparenting and cognitive function.

CONCLUSION

The results emphasized the significance of policymakers considering the consequences of intergenerational care and family support when formulating and executing social service policies targeted at the middle-aged and older population in China.

Impact of Caregiving on Cognitive Functioning: Evidence From the China Health and Retirement Longitudinal Study

OBJECTIVES

Few studies have examined the association between caregiving and the cognitive functioning of caregivers. This study explored the association between caring for family members and cognition and how the link differs by caregiving intensity and caregiving types. Furthermore, rural-urban and gender heterogeneity were investigated.

METHODS

This study analyzed Waves 2011, 2013, and 2018 of the China Health and Retirement Longitudinal Study, with cognitive functioning assessed in 3 dimensions: memory, executive function, and orientation function. The cognition trajectories between caregivers and noncaregivers were compared with the growth curve model.

RESULTS

Results demonstrated a positive association between caregiving and cognitive functioning (β = 0.249, p < .001). Considering caregiving intensity, the positive association was only found in low (β = 0.335, p < .001) and moderate-intensity caregivers (β = 0.250, p < .05) but not in high-intensity caregivers. Moreover, grandparents, adult children, and multiple caregivers had a higher average cognition level at age 60 than noncaregivers (all β > 0, all p < .05), and adult child caregivers exhibited a significantly slower rate of decline in cognition across age (β = 0.040, p < .01). However, spousal caregivers showed no significant disparities with noncaregivers. Moreover, the impact of caregiving on memory function is more apparent among urban adults.

DISCUSSION

Results indicate that caregiving can benefit cognitive function. This study proposes considering caregiving intensity and caregiving types when exploring caregiving and cognition. Based on these findings, policy-makers may overcome the challenges involved in establishing and developing a supportive informal care system in China.

Network analysis of cold cognition and depression in middle-aged and elder population: the moderation of grandparenting

Background

Cognitive decline and negative emotions are common in aging, especially decline in cold cognition which often co-occurred with depression in middle-aged and older adults. This study analyzed the interactions between cold cognition and depression in the middle-aged and elder populations using network analysis and explored the effects of grandparenting on the cold cognition-depression network.

Methods

The data of 6,900 individuals (≥ 45 years) from the China Health and Retirement Longitudinal Study (CHARLS) were used. The Minimum Mental State Examination (MMSE) and the Epidemiology Research Center Depression Scale-10 (CESD-10) were used to assess cold cognition and depressive symptoms, respectively. Centrality indices and bridge centrality indices were used to identify central nodes and bridge nodes, respectively.

Results

Network analysis showed that nodes "language ability" and "depressed mood" were more central nodes in the network of cold cognition and depression in all participants. Meantime, nodes "attention," "language ability" and "hopeless" were three key bridge nodes connecting cold cognition and depressive symptoms. Additionally, the global connectivity of the cold cognition and depression network was stronger in the non-grandparenting than the grandparenting.

Conclusion

The findings shed a light on the complex interactions between cold cognition and depression in the middle-aged and elder populations. Decline in language ability and depressed mood can serve as predictors for the emergence of cold cognitive dysfunction and depression in individuals during aging. Attention, language ability and hopelessness are potential targets for psychosocial interventions. Furthermore, grandparenting is effective in alleviating cold cognitive dysfunction and depression that occur during individual aging.

Intersectional inequalities in the transition to grandparenthood and cognitive functioning: A longitudinal Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA)

Objectives

With aging societies, more people become vulnerable to experiencing cognitive decline. While normal aging is associated with a deterioration in certain cognitive abilities, little is known about how social determinants intersect to create late-life cognitive functioning inequalities. Simultaneously, the role of grandparenthood is central for older adults and their families. There are indications that social determinants intersect to modulate the effect of the transition to grandparenthood, but further evidence is needed. Our study investigates the relation of transition to grandparenthood with cognitive functioning and explores differences across intersectional strata.

Methods

Using longitudinal data from the Survey of Health, Ageing and Retirement in Europe, we analyzed a sample of 19,953 individuals aged 50-85 without grandchildren at the baseline. We applied Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy to investigate cognitive functioning differences across 48 intersectional strata, defined by sex/gender, migration, education, and occupation. We allowed the impact of becoming a grandparent to vary across strata by including random slopes.

Results

Intersectional strata accounted for 17.43% of the overall variance in cognitive functioning, with most of the stratum-level variation explained by additive effects of the stratum-defining characteristics. Transition to grandparenthood was associated with higher cognitive functioning, with a stronger effect for women. Stratum-level variation in the grandparenthood effect was modest.

Discussion

This study highlights the importance of social determinants for understanding heterogeneities in the association of transition to grandparenthood with cognitive functioning. Adopting an intersectional lens is useful to decompose inequalities and derive tailored interventions to promote equal healthy aging.

Intergenerational caregiving on mental health of middle-aged and older adults in China: empirical insights

Introduction

The impact of intergenerational caregiving on the mental health of providers remains a controversial topic, especially in countries like China where it is prevalent. Given the country's aging population and recent liberalization of the two-child policy, understanding the effects of intergenerational caregiving on the mental health of middle-aged and older adult(s) individuals is crucial. This study aimed to explore the impact of intergenerational caregiving on mental health among middle-aged and older adult(s) individuals.

Methods

We analyzed data from the China Health and Aging Tracking Survey (CHARLS) 2013, consisting of 6602 participants finally. Personal information, family structure, financial support, health status, and physical measurements were selected for analysis. Correlation and regression analyses were used for relationships among variables controlling for potential confounding variables. Mental health status was evaluated using the depression self-rating scale.

Results

There is a significant positive effect of intergenerational care on the mental health of middle-aged and older adult(s) people. Additionally, we re-profiled intergenerational care variables by considering the number and length of intergenerational caregivers, and found that the effects remained significant. Furthermore, the effects of intergenerational care vary across subgroups based on gender, age, nature of usual residence, marital status, and physical health status. Finally, we identified two mechanisms through which intergenerational caregiving positively affects mental health: intergenerational financial support and intergenerational spiritual support.

Discussion

These findings have important implications for policymakers, healthcare professionals, and family members in promoting the mental health of middle-aged and older adult(s) individuals in China.

Social connections and participation among people with mild cognitive impairment: barriers and recommendations

Objective

Social connections and participation are essential for individuals with mild cognitive impairment (MCI) to prevent the progression of cognitive decline and enhance their overall well-being. However, existing research has primarily focused on environmental barriers, overlooking personal factors and the interconnected nature of these barriers. Moreover, there is a lack of understanding regarding social connections and participation challenges specific to people with MCI in low- and middle-income countries. Therefore, this study aimed to explore the barriers that hinder social connections and participation among people with MCI in China and investigate opportunities to design appropriate supportive interventions.

Methods

Thirty-one people with MCI (13 males and 18 females; mean age = 82.74 years, SD = 7.69; mean MoCA score = 21.26, SD = 2.44) and 13 caregivers were recruited to attend focus groups. In addition, 10 therapists were interviewed using a semi-structured interview guide. Focus groups and interviews were audio-recorded, transcribed, and analyzed using a framework analysis approach.

Results

We found that the ability to build social connections among people with MCI is affected by mobility challenges, intensive grandparenting responsibilities, availability of suitable activities, and feelings of exclusion in a closed-minded community environment. Personal reasons, such as lower social efficacy, inability to find suitable social activities, and intensive family responsibilities, discourage people with MCI from social participation. The digital literacy of people with MCI depends on their motivation to learn and use digital tools; people with MCI who live in a community have a higher digital literacy than those living in care centers. The motivation to achieve digital literacy is affected by perceived benefits, costs of technology use, and social influence.

Conclusion

Multidimensional initiatives are needed to address barriers to social connections, participation, and technology adoption among individuals with MCI. This includes organizing and engaging in social activities, promoting awareness and education on the importance of social participation, and exploring technology-based interventions to improve memory and storytelling abilities. These efforts can create a supportive environment and empower individuals with MCI to participate actively in social interactions, enhancing their overall well-being.

Comparison of the Quality of Life of Physically Active and Inactive Grandmothers Caring and Non-caring for Grandchildren: A Cross-Sectional Study

Background

Nowadays, grandparents have a major role in taking care of their grandchildren. Also, caring for grandchildren is a common and normative experience for many Iranian grandparents. The present study aimed to compare the quality of life of physically active and inactive grandmothers caring and non-caring for grandchildren.

Methods

This analytical cross-sectional study was conducted on 300 grandmothers at the age range of 50 to 70 years old, who lived in Bojnurd, northeastern Iran (2018). Data were collected using the questionnaires of 36-Item Short Form Health Survey (SF-36) and Baecke Physical Activity, and demographic information.

Results

The total scores of quality of life in caring physically active, physically inactive, non-caring physically active and non-caring physically inactive grandmothers were 76.95±6.33, 71.74±9.41, 75.56±5.9, and 56.06±11.23, respectively. There was a significant difference in the comparison of the quality of life score in caring grandmothers in two active and inactive groups (P<0.001). In addition, the quality of life score of non-caring grandmothers indicated a significant difference in physically active and inactive grandmothers (P<0.001).

Conclusion

According to the results of this study, it seems that caring physically active grandmothers have higher quality of life. It can be suggested that the grandmothers who care for their grandchildren may improve their health and quality of life by incorporating the programs to increase physical activities in their daily life.

Association between caring for grandchildren based on living arrangements and cognitive function among Chinese middle-aged and older adults: The mediating roles of social activities and depressive symptoms

Introduction

In the context of an aging population and age-related conditions increasing, the increasing number of middle-aged and older adults are involved in grandchildren care. This study aimed to 1) explore the association between caring for grandchildren based on living arrangements and cognitive function among Chinese middle-aged and older adults; and 2) investigate the mediating roles of social activities and depressive symptoms in the aforementioned association.

Methods

This study selected 5490 Chinese people (≥45 years old) from the 2018 China Health and Retirement Longitudinal Study (CHARLS). Participants answered questions related to socio-demographics, the Mini-mental State Examination, the intensity of grandchildren care, the Center for Epidemiological Studies Depression Scale, and social activity.

Results

The results showed that caring for grandchildren and cohabiting with a spouse was positively associated with cognitive function among Chinese middle-aged and older adults (B = 0.829, p < 0.001). Furthermore, there was a positive association between providing intensive or no-intensive grandchildren care and cognitive function. In contrast, caring for grandchildren but not cohabiting with a spouse was negatively associated with cognitive function (B = -0.545, p < 0.05). Moreover, directly and indirectly, caring for grandchildren was significantly associated with cognitive function among Chinese middle-aged and older adults, as mediated by social activities and depressive symptoms.

Discussion

The findings emphasize that living arrangements, social engagement, and psychological health could be considered when encouraging grandparent care as formal care.

The Implications of Intergenerational Relationships for Minority Aging: a Review of Recent Literature

Purpose of Review

This study aims to understand how intergenerational relationships impact minority aging in the USA. We reviewed studies published in the last 5 years that examine both familial and non-familial intergenerational relationships.

Recent Findings

Intergenerational relationships can have positive and negative implications for minority aging. Minority older adults benefit most from these relationships when they increase social interaction and/or offer social support by reducing acculturative stress, providing emotional closeness, or increasing access to tangible resources. At the same time, these relationships can be sources of strain as they lead to burden among already disadvantaged groups.

Summary

Future studies should explore the impact of intergenerational relations among more diverse subgroups of older adults and identify mechanisms linking intergenerational relationships to health-related outcomes among minority older adults. Further, longitudinal cohort studies and randomized trials are needed to test mechanisms and evaluate the effectiveness of promising intergenerational interventions.

Grandparenting and subjective well-being in China: The moderating effects of residential location, gender, age, and income

Grandparenting is a social determinant of older adults' subjective well-being (SWB) worldwide, and is receiving increasing scholarly attention. Grandparenting is particularly prevalent in China because of the increasing number of women in the labor force, shortages of daycare services, and intergenerational bonds. Based on three waves (2011, 2013, and 2015) of the China Health and Retirement Longitudinal Study (n = 14,846), we used pooled ordinary least squares (POLS) regression to examine the association between grandparenting and Chinese older adults' SWB and the moderating effects of residential location (rural/urban), gender, age, and income. We measured SWB by four outcomes: self-rated health, life satisfaction, depressive symptoms, and cognitive function. Our findings indicate that intensive grandparenting is positively associated with older adults' life satisfaction. Older adults providing a low-to-high intensity of grandparenting have better cognitive function than non-caregivers. Among caregivers, a moderate level of grandparenting is associated with better cognitive function. Residential location, age, and income are significant moderators. For example, high-intensity grandparenting is positively associated with rural grandparents' but not urban grandparents' life satisfaction. Although younger grandparents have better self-rated health, higher life satisfaction, and fewer depressive symptoms than their older counterparts if they provide grandparenting care, grandparenting is more beneficial for older grandparents' cognitive function. Both low and high intensities of grandparenting are positively related to self-rated health and cognitive function for grandparents with lower incomes. Overall, the findings of this study indicate how grandparenting is related to the SWB of older people in China in different social groups and of people living in different locations.

Developing and maintaining intergenerational relationships in an economically vulnerable community: findings from the Flint women's study

Few studies describe how community disadvantage impacts intergenerational relationships. Using interviews with women and service providers (n = 100), we explored benefits and challenges of intergenerational relationships in Flint, Michigan, an economically vulnerable community. Women valued relationships that increased social connections and generativity; however, few community resources promoted such relationships. Intergenerational relationships were important for leaving a social legacy in lieu of a meaningful economic legacy. Some middle-aged women are overwhelmed by caregiving, balancing employment while caring for multiple generations. Women desired intergenerational activities that include children and younger adult women. Further, caregiving programs should attend to the needs of middle-aged caregivers.

The Experience of Grandparenting Young Children

This study examines the experience of grandparents providing regular childcare to their young grandchildren in China. Due to unique cultural and social factors, regular childcare provided by grandparents is becoming increasingly common in China. Unfortunately, published research on this topic does not provide a sufficient understanding of the experiences of grandparents who provide the regular care and the impact this has on their life. A qualitative, cross-sectional study was conducted in an urban village setting in Changsha China, where participants (N = 11) were recruited using purposive sampling. Data were collected between April 2019 and June 2019 and thematically analyzed using a seven-step modified procedure established by Colaizzi. Three key themes were identified: (1) Dominant factors motivating grandparenting; (2) Sweet burden of grandparenting; and, (3) Unmet needs. Study findings showed that while the Chinese grandparents perceived value and benefits to providing regular childcare, there are also significant challenges that need to be addressed. Interventions at a household and community level can be implemented to improve their childcare role.

Change in Episodic Memory With Spousal Loss: The Role of Social Relationships

OBJECTIVES

The spousal relationship is one of the most important social contexts in old age, and the loss of a spouse/partner is associated with stress and cognitive decline. In the present study, we examined whether social relationships can buffer potential negative effects of spousal loss on cognition. We examined the role of social network, social activities, and perceived deficiencies in social relationships (loneliness).

METHOD

We used longitudinal data between 1998 and 2012 from 2,074 participants of the Health and Retirement Study, who had experienced spousal loss during the study period. Multilevel modeling was used to examine how time-varying indicators of social network, social activities, and loneliness were related to age-related trajectories of episodic memory prior to and after spousal loss. Analyses controlled for gender, race/ethnicity, education, time-varying functional health, and being repartnered/remarried.

RESULTS

Having children living within 10 miles and providing help to others buffered negative effects of widowhood on episodic memory. In addition, within-person increase in providing help to others buffered against decline in episodic memory after spousal loss. Having friends in the neighborhood, more frequent social visits, providing help to others, volunteering, and lack of loneliness were related to higher episodic memory, while having relatives in the neighborhood was related to lower episodic memory.

DISCUSSION

Our findings suggest that social networks, social activities, and loneliness are related to levels of cognitive function at the time of spousal loss and that social relationships can buffer negative effects of spousal loss on cognitive function. Implications for future research are discussed.

Cognitive Function Among Noncustodial Grandparents in China and the United States: A Cross-National Perspective

The current study aimed to investigate the association between grandparenting and cognitive function over time in noncustodial grandparents in China and the United States. Lagged dependent variable (LDV) approach and linear regression models were applied to analyze a sample of 1,411 Chinese and 6,579 American adults aged 65 and above from the China Health and Retirement Longitudinal Study (CHARLS, 2011-2013) and the U.S. Health and Retirement Study (HRS, 2012-2014). Grandparenting involvement was associated with less decline in episodic memory for grandparents and greater level of grandparenting had no negative effect on mental status and global cognitive function in noncustodial grandparents in China and the United States. The impact of grandparenting on cognitive function was conditioned on caregiving intensity, gender, urban/rural residence, and nation. Findings of the study suggest that greater attention on grandparenting facilitation might yield improved research, social support, policy, and interventions on cognitive health for the general older population.

Longitudinal impacts of grandparent caregiving on cognitive, mental, and physical health in China

OBJECTIVES

Although studies have documented the effects of grandparenting, little is known about grandparents' long-term health outcomes in terms of optimal engagement with grandchildren, and whether age, gender, or location make a difference. This study explores the longitudinal impacts of grandparenting on health, with considerations for subgroup differences.

METHODS

Using three waves of China Health and Retirement Longitudinal Study, we used propensity score analysis combined with multilevel analysis to examine the longitudinal effect of grandparenting (no, low-, moderate-, and high-intensity) on health (self-rated health, mobility limitations, depressive symptoms, and cognition) among 4,925 grandparents with at least one grandchild, and how impact varies by age, gender, and urban/rural areas.

RESULTS

A nonlinear relationship between grandparenting and health was observed. Compared to those not providing care, grandparents who provided care at a low-to-moderate level were more likely to have fewer mobility limitations and depressive symptoms and better cognition. High intensity had no positive impacts on health. The effects of grandparenting on health operated differently across subgroups. Older grandparents showed better physical, mental, and cognitive health compared to their younger counterparts. Both genders had fewer mobility limitations if they provided care at a low-to-moderate level, although females reported better self-rated health. Rural grandparents reported better physical health; whereas urban grandparents reported better cognition.

CONCLUSION

Grandparenting could improve health in later life; however, there are complex interactions at play. Policies aimed at supporting grandparenting should consider optimal hours of care relevant to age, gender, and urban/rural contexts.

The relationship between fertility history and incident dementia in the US Health and Retirement Study

OBJECTIVES

An emerging literature suggests that fertility history, which includes measures of parity and birth timing, may influence cognitive health in older ages, especially among women given their differential exposure to pregnancy and sex hormones. Yet, few studies have examined associations between measures of fertility history and incident dementia in population-based samples.

METHODS

We examined the associations between parity, younger age at first birth, and older age at last birth with incident dementia over a 16-year period in a prospective sample of 15,361 men and women aged 51-100 years at baseline drawn from the Health and Retirement Study. We used Cox regression and the Fine and Gray model to obtain cause-specific (csHRs) and subdistribution hazard ratios (sdHRs) for incident dementia from gender-stratified models in which we accounted for the semi-competing risk of death.

RESULTS

During the follow-up period (median 13.0 years), the crude incidence rate for dementia was 16.6 and 19.9 per 1,000 person-years for men and women, respectively. In crude models estimating csHRs, higher parity (vs. parity 2) and younger age at first birth were associated with increased risk of dementia for both genders. These associations did not persist after full covariate adjustment. Across all models in which we estimated sdHRs, we observed a positive relationship between older age at last birth and incident dementia for women only.

DISCUSSION

In this population-based, multi-ethnic cohort, we observed limited evidence for an association between measures of fertility history and incident dementia among men and women after adjusting for potential confounders.

The Role of Social Connection/Engagement in Episodic Memory Change in Stroke

BACKGROUND AND OBJECTIVES

Positive associations between social connection/engagement and cognitive function are well documented. However, little is known about whether social connection/engagement can buffer the impact of serious brain injury such as stroke on cognitive functioning.

RESEARCH DESIGN AND METHODS

Participants were 898 individuals with incident stroke from the Health and Retirement Study (HRS) between 1998-2012. Multilevel modeling was used to examine how social connection/engagement were associated with episodic memory pre- and post-stroke. Models controlled for age, gender, education, race/ethnicity, number of health conditions, and functional health.

RESULTS

Participants who were lonely pre-stroke recalled significantly fewer words at time of stroke, and participants who had children residing within 10 miles pre-stroke showed significantly less decline in word recall over time. Participants who provided help to others pre-stroke showed less stroke-related decline in word recall. Within-person increase in partnered status, having friends, and helping others were related to better word recall in the post-stroke period.

DISCUSSION AND IMPLICATIONS

Higher pre-stroke levels of social connection/engagement predicted better episodic memory at stroke, smaller decline in episodic memory with stroke, and less decline in episodic memory over time. Increases in social connection/engagement from pre- to post-stroke also predicted better post-stroke episodic memory. Beyond the widely documented benefits of social connection/engagement to well-being, they may also increase cognitive stimulation and cognitive reserve and thus contribute to stroke recovery in the cognitive domain. Social connection/engagement is an important and modifiable risk factor in older adults.

Intergenerational Ties in Context: Association between Caring for Grandchildren and Cognitive Function in Middle-Aged and Older Chinese

Grandchild caregiving is suggested to improve the elderly’s cognitive function, but the specific relationship remains under-investigated. Considering gender disparity, this study aimed to understand the relationship between grandchild caregiving and cognition. In total, 7236 Chinese residents (≥45 years old) were selected from the 2015 China Health and Retirement Longitudinal Study (CHARLS). The China Health and Retirement Longitudinal Study Harmonized Cognitive Assessment Protocol (CHARLS-HCAP) was used to measure cognition. Grandparenting was measured from three dimensions: caregiving frequency, intensity, and the number of grandchildren cared for. The relationship was examined by multivariate linear regression, with age as a moderator. The results showed that the majority of respondents provided care to their grandchildren, especially grandmothers. Grandchild caregiving was positively associated with cognition (β = 0.686, 95% CI = 0.334–1.038), especially in the older-aged group. Moderate, not regular grandparenting, or caring for one grandchild was more positively associated with cognitive function. However, intensive and regular grandchild care was significantly associated with cognition only in men. No moderating effects of age were found in women. The study confirmed that moderate intensity and frequency of caregiving was related to better cognitive function in middle-aged and older Chinese population, whereas cultural context and gender differences could be considered when designing targeted policies.

Informal Caregiving, Poor Mental Health, and Subjective Cognitive Decline: Results From a Population-Based Sample

The current study examined potential gender differences in the associations between informal caregiving, poor mental health, and subjective cognitive decline (SCD). Data were obtained from the U.S. Behavioral Risk Factor Surveillance System (N = 16,042; 9,410 women, 6,632 men). Multivariate linear and logistic regression models were used to obtain adjusted βs and odds ratios (ORs), and 95% confidence intervals (CIs) depicting the association between informal caregiving, poor mental health, and SCD overall and by gender. Caregiving was positively associated with poor mental health among men (adjusted β = 2.60; 95% CI [2.59, 2.62]) and women (adjusted β = 0.40; 95% CI [0.23, 0.57]). Poor mental health was positively associated with SCD among men (adjusted OR = 1.05; 95% CI [1.02, 1.08]) and women (adjusted OR = 1.07; 95% CI [1.04, 1.10]). Poor mental health may be associated with SCD, irrespective of gender, and additional studies are needed that will identify key variables influencing SCD among male and female informal caregivers.

Multigenerational social support in the face of the COVID-19 pandemic

Research documents high levels of instrumental, financial, and expressive support exchanges within multigenerational families in the 21st century. The COVID-19 pandemic poses unique challenges to support exchanges between the generations; however, the pandemic may provide opportunities for greater solidarity within families. In this review, we draw from theoretical perspectives that have been used to study family relationships to understand the implications of the pandemic for multigenerational families: the life course perspective, the intergenerational solidarity model, and rational choice/social exchange theory. We review literature on multigenerational relationships in the United States and discuss how established social support patterns and processes may be altered by the COVID-19 pandemic. We reflect on how the impact of the COVID-19 pandemic on multigenerational relationships may vary by gender, race, ethnicity, and socioeconomic status. Finally, we provide directions for future researchers to pursue in order to understand the lasting impacts of the COVID-19 pandemic on multigenerational ties.

Providing regular grandchild care: Grandparents' psychological and physical health

OBJECTIVES

To examine the associations between intensity of providing regular grandchild care and positive affect (PA) and negative affect (NA), heart rate variability (HRV) and somatic symptoms.

METHODS

This was a cross-sectional study involving 104 individuals (aged 59-82) who provide at least 5 h a week of regular care for their grandchildren. The study model was assessed using structural equation modeling.

RESULTS

Intensity of regular care (mean hours per week: M = 14.8, SD = 11.2) was associated with higher PA and lower NA. Higher perceived role overload, higher NA and lower PA were associated with lower HRV and somatic symptoms. The fit indices indicated a good model fit.

CONCLUSIONS

The results suggest that healthcare professionals should be aware of the positive and negative implications of caring for grandchildren on their older patients, including the increased risk of future morbidity, as indicated by lower HRV.

Benefits of Grandparental Caregiving in Chinese Older Adults: Reduced Lonely Dissatisfaction as a Mediator

Objective

The purpose of the present study is twofold: (1) to investigate the differences in terms of physical and mental health between those who provide grandparental care and those who do not and (2) to explore the mechanism that connects grandparental caregiving and health-related outcomes.

Methods

Two studies (a cross-sectional and a short-term longitudinal follow-up) were conducted. The cross-sectional study (Study 1) examined 148 older adults who provided grandparental care and another 150 older adults who did not. A small longitudinal follow-up study (Study 2) was conducted among 102 older adults randomly selected from Study 1, of which 52 were older adults who provided grandparental care, and another 50 older adults were those who did not. Health status (measured by SF-36), lonely dissatisfaction (measured by Lonely Dissatisfaction Subscale of PGC-MS), and cognitive functions (measured by subscales of WAIS) as well as demographics were measured in both studies.

Results

Results of both the cross-sectional and longitudinal studies showed that, compared with older adults who did not provide grandparental care, those providing grandparental care had significantly better physical and mental health as well as reduced lonely dissatisfaction. Further path analysis showed that lonely dissatisfaction mediated the association between providing grandparental care and enhancement in functions such that providing grandparental care could reduce lonely dissatisfaction, which, in turn, could improve their physical and mental health even after controlling for their cognitive functions.

Discussion

These results suggest that providing grandparental care can improve older adults’ physical and mental health through reduced lonely dissatisfaction.
