Family caregiving and all-cause mortality: findings from a population-based propensity-matched analysis

Understanding caregiver burden and quality of life in Kerala's primary palliative care program: a mixed methods study from caregivers and providers' perspectives

BACKGROUND

Family caregivers are vital for long-term care for persons with serious health-related suffering in Kerala. Long-term caregiving and ageing may become burdensome and detrimental to patients and caregivers. We compared the caregiver burden and quality-of-life of ageing caregivers with younger caregivers. We also explored the palliative care nurses' perceptions of the family caregivers' issues.

METHODS

We did a mixed method study focusing on two groups: (i) three in-depth interviews and a cross-sectional survey among 221 caregivers of palliative care patients in five randomly selected panchayats (most peripheral tier of three-tier local self-government system in India concerned with governance of a village or small town) of Kollam district, Kerala, as part of development and validation of the Achutha Menon Centre Caregiver Burden Inventory; (ii) five in-depth interviews with purposively selected primary palliative care nurses as part of a study on local governments and palliative care. We used a structured interview schedule to collect cross-sectional data on sociodemographic and caregiving-related characteristics, caregiver burden, and health-related quality of life using the EuroQol EQ5D5L and interview guidelines on caregiver issues tailored based on participant type for qualitative interviews.

RESULTS

Older caregivers comprised 28.1% of the sample and had significantly poorer health and quality-of-life attributes. More senior caregivers experiencing caregiver burden had the lowest mean scores of 0.877 (Standard deviation (SD 0.066, 95% confidence intervals (CI) 0.854-0.899) followed by younger caregivers with high burden (0.926, SD 0.090, 95% CI 0.907-0.945), older caregivers with low burden (0.935, SD 0.058, 95% CI 0.912-0.958) and younger caregivers with low burden (0.980, SD 0.041, 95% CI 0.970-0.990). Caregivers faced physical, psychological, social, and financial issues, leading to a caregiver burden. The relationships between the palliative care nurses and family caregivers were complex, and nurses perceived caregiver burden, but there were no specific interventions to address this.

CONCLUSION

In our study from Kollam, Kerala, three out of ten caregivers of palliative care patients were 60 years of age or older. They had significantly lower health-related quality of life, particularly if they perceived caregiver burden. Despite being recognized by palliative care nurses, caregiver issues were not systematically addressed. Further research and suitable interventions must be developed to target such problems in the palliative care programme in Kerala.

Insomnia Symptom Trajectory of Spouse Caregivers of Older Adults with Functional Limitations

OBJECTIVES

This study examined the long-term impact of spouse caregiving on insomnia symptoms, compared to propensity-score matched non-caregivers.

METHODS

Health and Retirement Study data between 2006 and 2018 were used. Caregivers (n = 403) were respondents (aged 50+) who assisted their heterosexual spouses in performing (instrumental) activities of daily living at baseline. Non-caregivers were matched using a propensity score matching procedure based on baseline characteristics. Insomnia symptoms were measured every 4 years for both groups. Poisson mixed-effect models estimated the association between caregiver status and insomnia symptoms.

RESULTS

Compared to matched non-caregivers, caregivers had similar severity of insomnia symptoms at baseline (β caregiver  = 0.018, 95% CI = -0.089, 0.124) and reported a similar yearly change rate (β caregiver × time  = -0.008, 95% CI = -0.017, 0.001). No moderation effects of care-recipients' dementia status and social support were significant.

CONCLUSIONS

In this study sample, there is no evidence that spouse caregivers, specifically those who performed light duties, experience more severe insomnia symptoms than non-caregivers.

CLINICAL IMPLICATIONS

Spouse caregiving, especially in a light-duty capacity, may not be detrimental to the caregivers' sleep health. More data are needed regarding insomnia in spouse caregivers with heavy duties of care to fully assess the health impact of the caregiving experience.

Caregiving and all-cause mortality in postmenopausal women: Findings from the Women's Health Initiative

BACKGROUND

Caregiving is commonly undertaken by older women. Research is mixed, however, about the impact of prolonged caregiving on their health, well-being, and mortality risk. Using a prospective study design, we examined the association of caregiving with mortality in a cohort of older women.

METHODS

Participants were 158,987 postmenopausal women aged 50-79 years at enrollment into the Women's Health Initiative (WHI) who provided information on current caregiving status and caregiving frequency at baseline (1993-1998) and follow-up (2004-2005). Mortality was ascertained from baseline through March of 2019. Cox regression with caregiving status defined as a time-varying exposure was used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for mortality, adjusting for sociodemographic factors, smoking, and history of diabetes, hypertension, cardiovascular disease (CVD), and cancer. Stratified analyses explored whether age, race-ethnicity, depressive symptoms, frequency of caregiving, optimism, and living status modified the association between caregiver status and mortality.

RESULTS

At baseline, 40.7% of women (mean age 63.3 years) self-identified as caregivers. During a mean 17.5-year follow-up, all-cause mortality (50,526 deaths) was 9% lower (multivariable-adjusted HR = 0.91, 95% CI: 0.89-0.93) in caregivers compared to non-caregivers. The inverse association between caregiving and all-cause mortality did not differ according to caregiving frequency or when stratified by age, race-ethnicity, depressive symptoms, optimism, or living status (interaction p > 0.05, all). Caregiving was inversely associated with CVD and cancer mortality.

CONCLUSION

Among postmenopausal women residing across the United States, caregiving was associated with lower mortality. Studies detailing the type and amount of caregiving are needed to further determine its impact on older women.

Understanding the health effects of caregiving stress: New directions in molecular aging

Dementia caregiving has been linked to multiple health risks, including infectious illness, depression, anxiety, immune dysregulation, weakened vaccine responses, slow wound healing, hypertension, cardiovascular disease, metabolic syndrome, diabetes, frailty, cognitive decline, and reduced structural and functional integrity of the brain. The sustained overproduction of proinflammatory cytokines is a key pathway behind many of these risks. However, contrasting findings suggest that some forms of caregiving may have beneficial effects, such as maintaining caregivers' health and providing a sense of meaning and purpose which, in turn, may contribute to lower rates of functional decline and mortality. The current review synthesizes these disparate literatures, identifies methodological sources of discrepancy, and integrates caregiver research with work on aging biomarkers to propose a research agenda that traces the mechanistic pathways of caregivers' health trajectories with a focus on the unique stressors facing spousal caregivers as compared to other informal caregivers. Combined with a focus on psychosocial moderators and mechanisms, studies using state-of-the-art molecular aging biomarkers such as telomere length, p16INK4a, and epigenetic age could help to reconcile mixed literature on caregiving's sequelae by determining whether and under what conditions caregiving-related experiences contribute to faster aging, in part through inflammatory biology. The biomarkers predict morbidity and mortality, and each contributes non-redundant information about age-related molecular changes -together painting a more complete picture of biological aging. Indeed, assessing changes in these biopsychosocial mechanisms over time would help to clarify the dynamic relationships between caregiving experiences, psychological states, immune function, and aging.

The role of caregiving in cognitive function and change: The REGARDS study

Chronic stress is associated with negative health outcomes, including poorer cognition. Some studies found stress from caregiving associated with worse cognitive functioning; however, findings are mixed. The present study examined the relationship between caregiving, caregiving strain, and cognitive functioning. We identified participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study who were family caregivers at baseline assessment and used propensity matching on 14 sociodemographic and health variables to identify matched noncaregivers for comparison. Data included up to 14 years of repeated assessments of global cognitive functioning, learning and memory, and executive functioning. Our results showed that when compared to noncaregivers, caregivers had better baseline scores on global cognitive functioning and word list learning (WLL). Among caregivers, a lot of strain was associated with better WLL and delayed word recall in the unadjusted model only. Caregivers with a lot of strain had higher depressive symptoms but not significantly higher high-sensitivity c-reactive protein (hsCRP) at baseline compared to caregivers with no or some strain after covariate adjustment. Although caregiving can be highly stressful, we found caregiving status and caregiving strain were not associated with cognitive decline. More methodologically rigorous studies are needed, and conclusions that caregiving has negative effects on cognition should be viewed with caution.

Co-designing an interactive artificial intelligent system with post-stroke patients and caregivers to augment the lost abilities and improve their quality of life: a human-centric approach

Objectives

The motor disability due to stroke compromises the autonomy of patients and caregivers. To support autonomy and other personal and social needs, trustworthy, multifunctional, adaptive, and interactive assistive devices represent optimal solutions. To fulfill this aim, an artificial intelligence system named MAIA would aim to interpret users' intentions and translate them into actions performed by assistive devices. Analyzing their perspectives is essential to develop the MAIA system operating in harmony with patients' and caregivers' needs as much as possible.

Methods

Post-stroke patients and caregivers were interviewed to explore the impact of motor disability on their lives, previous experiences with assistive technologies, opinions, and attitudes about MAIA and their needs. Interview transcripts were analyzed using inductive thematic analysis.

Results

Sixteen interviews were conducted with 12 post-stroke patients and four caregivers. Three themes emerged: (1) Needs to be satisfied, (2) MAIA technology acceptance, and (3) Perceived trustfulness. Overall, patients are seeking rehabilitative technology, contrary to caregivers needing assistive technology to help them daily. An easy-to-use and ergonomic technology is preferable. However, a few participants trust a system based on artificial intelligence.

Conclusion

An interactive artificial intelligence technology could help post-stroke patients and their caregivers to restore motor autonomy. The insights from participants to develop the system depends on their motor ability and the role of patients or caregiver. Although technology grows exponentially, more efforts are needed to strengthen people's trust in advanced technology.

Support-Giving Is Associated With Lower Systemic Inflammation

BACKGROUND

Support-giving has emerged as a health-relevant social behavior, such that giving more support is associated with better physical health. However, biological mechanisms by which support-giving and health are linked remain unclear. Whether support-giving uniquely relates to health relative to other psychosocial factors is also an open research question.

PURPOSE

Two studies test the hypothesis that support-giving is uniquely (over-and-above other psychosocial factors) related to lower systemic inflammation, a biological correlate of health.

METHODS

Cross-sectional associations of support-giving with markers of systemic inflammation (i.e., interleukin-6 [IL-6], C-reactive protein [CRP]) were examined in two independent samples of midlife adults (Study 1, n = 746; Study 2, n = 350).

RESULTS

Consistent with hypotheses, giving to more social targets (to family and friends, and also volunteering for various causes), but not receiving support from similar targets, was associated with lower IL-6. In conceptual replication and extension with a different measure of support-giving, higher frequency of support-giving behavior was associated with lower IL-6, even after adjusting for social network size and individual differences in social desirability. There were no associations between support-giving and CRP in either sample.

CONCLUSIONS

Future research needs to establish causality and directly test mechanistic pathways, but together, findings reaffirm the health-relevance of support-giving behavior and shed light on a promising biological mechanism by which such effects may occur.

Caregiving and changes in health-related behaviour

Potential health risks for informal caregivers have been hypothesised to be partly related to adverse changes in health-related behaviour, but evidence is limited. We examined whether smoking, drinking, eating, physical activity or leisure pursuits change in relation to co-resident or out-of-home caregiving (for someone outside the household), and if associations differ by sex, educational attainment, and welfare state typology. We conducted a longitudinal study using six waves of the Survey of Health, Ageing and Retirement in Europe, collecting data repeatedly from 2004 to 2017 for adults aged 50 years and older living in 17 European countries (57,962 individuals). To control for measured and unmeasured within-individual time-invariant confounders, we used fixed effects logistic models to analyse the repeated measures of caregiving, behaviour and covariates and estimated odds ratios (OR) with 95% confidence intervals (95%CI). Among male participants, unhealthy eating increased while smoking decreased [ORs 1.26 (95%CI 1.01-1.58) and 0.53 (0.36-0.78), respectively] in survey waves in which they provided co-resident care, compared with the waves that they did not. Among female participants, there was little change in behaviour between waves with and without co-resident caregiving. When providing out-of-home care, lacks of physical activity and leisure pursuits declined. But in the same time, drinking increased both men and women, and especially among individuals with lower educational attainment and residing in non-Nordic countries. To conclude, overall, increased drinking when providing out-of-home care was most consistent, especially among individuals with lower educational attainment and residing in non-Nordic countries. Otherwise, the associations varied by the type of care, behaviour and population subgroups. These findings indicated that not all caregivers are susceptible to behavioural changes, and that not all behaviour may be involved similarly in linking caregiving to health risks. This opens possibilities to target specific behaviour and groups to prevent adverse changes in health behaviour in caregivers.

Measurement of Prosocial Tendencies: Meta-Analysis of the Generalization of the Reliability of the Instrument

The Prosocial Tendencies Measure (PTM) and its revised version (PTM-R) are used internationally to measure prosocial behaviors in different life situations. To obtain accumulated evidence of the report and the reliability of its scores, a meta-analysis of the reliability of internal consistency was performed. The databases of Web of Science (WoS) and Scopus were reviewed and all the studies that applied it from 2002 to 2021 were selected. Results: Only 47.9% of the studies presented the index of reliability of PTM and PTM-R. The meta-analytic results of the reliability report of the subscales that the PTM and the PTM-R have in common were: Public 0.78 (95% CI: 0.76-0.80), Anonymous 0.80 (95% CI: 0.79-0.82), Dire 0.74 (95% CI: 0.71-0.76), and Compliant 0.71 (95% CI: 0.72-0.78). Each one of them presents high levels of heterogeneity derived from the gender of the participants (percentage of women), the continent of the population, the validation design, the incentive to participate, and the form of application. It is concluded that both versions present acceptable reliabilities to measure prosocial behavior in different groups and situations, as adolescents and young people, but their clinical use is discouraged.

Associations of perceived stress, depressive symptoms, and caregiving with inflammation: a longitudinal study

OBJECTIVES

Higher inflammation has been linked to poor physical and mental health outcomes, and mortality, but few studies have rigorously examined whether changes in perceived stress and depressive symptoms are associated with increased inflammation within family caregivers and non-caregivers in a longitudinal design.

DESIGN

Longitudinal Study.

SETTING

REasons for Geographic And Racial Differences in Stroke cohort study.

PARTICIPANTS

Participants included 239 individuals who were not caregivers at baseline but transitioned to providing substantial and sustained caregiving over time. They were initially matched to 241 non-caregiver comparisons on age, sex, race, education, marital status, self-rated health, and history of cardiovascular disease. Blood was drawn at baseline and approximately 9.3 years at follow-up for both groups.

MEASUREMENTS

Perceived Stress Scale, Center for Epidemiological Studies-Depression, inflammatory biomarkers, including high-sensitivity C-reactive protein, D dimer, tumor necrosis factor alpha receptor 1, interleukin (IL)-2, IL-6, and IL-10 taken at baseline and follow-up.

RESULTS

Although at follow-up, caregivers showed significantly greater worsening in perceived stress and depressive symptoms compared to non-caregivers, there were few significant associations between depressive symptoms or perceived stress on inflammation for either group. Inflammation, however, was associated with multiple demographic and health variables, including age, race, obesity, and use of medications for hypertension and diabetes for caregivers and non-caregivers.

CONCLUSIONS

These findings illustrate the complexity of studying the associations between stress, depressive symptoms, and inflammation in older adults, where these associations may depend on demographic, disease, and medication effects. Future studies should examine whether resilience factors may prevent increased inflammation in older caregivers.

Caregiving: a risk factor of poor health and depression among informal caregivers in India- A comparative analysis

BACKGROUND

In an ageing society, the provision of long-term care is the prime need. In Indian cultural setting, family members are the informal, albeit primary caregivers to the elderly. Caregiving demands intense emotional and financial involvement. While taking care of elderly persons' health and wellbeing, these family members, acting as informal caregivers, may themselves become vulnerable to poor health due to additional stress and burden. Using a nationally representative survey, the study tried to identify how health condition varies within caregivers and a comparative analysis of how in similar socio-economic background health condition varies between caregivers and non-caregivers.

METHOD

The data, used for the analysis, is taken from Longitudinal Ageing Study in India (LASI), Wave I. Both descriptive and multivariable regression analysis are done in different models along with interaction effect of caregiving to understand the difference in health status between caregiver and non-caregivers.

RESULTS

Nearly 29% and 11% of the informal caregivers, reported to have depressive symptoms and poor self-rated health (SRH), respectively. Almost half of the caregivers, who provide care for more than 40 h a week, are diagnosed to have depressive symptoms. They are also at higher risk of having depressive symptoms (AOR 1.59 CI 1.16-2.18) and poor SRH (AOR 1.73 CI 1.11-2.69) than those who invest less than 40 h in a week. In almost every socio-economic condition, caregivers are at a higher risk of having depression and poor health than non-caregivers. Caregivers, who are widowed, live in rural areas or are not satisfied with current living arrangement are more vulnerable to have depressive symptoms. On the other hand, caregivers of age 45-59 years, widowed, male and who live only with their children with spouse absent, have almost 2 times higher odds of poor SRH than non-caregivers.

CONCLUSION

Caregivers are more susceptible to depression and poor self-rated health compared to non-caregivers irrespective of their socio-economic characteristics, only the magnitude of vulnerability varies.

Teaching Note-Supporting Homebound Older Adults and Caregivers Through Integrative Service Learning

The Supporting Older Adults & Caregivers: Integrative Service Learning (SOCIAL) partnership trains undergraduate social work students to provide practical home-based support for older adults with chronic illness and their family caregivers, serving as a pipeline for future leaders in older adult care. More than 2 million older adults are homebound, and 5 million need help leaving their homes due to physical limitations from chronic conditions or cognitive impairments. Family members often assume daily caregiving tasks to assist their loved ones, navigate health care systems, and provide much needed emotional support. The challenges of caregiving are further compounded by the problems associated with insufficient health care professionals who are trained to work with older adults. Integrative service learning models can provide home-based support to older adults while offering valuable, hands-on learning experiences for students. In this teaching note, we acknowledge a need for developing an educational pipeline that can provide training opportunities for students to work with older adults and their caregivers at home. We provide an example of an integrative service-learning model which offers valuable pedagogical experiences to baccalaureate students along with strategies for curriculum building, community engagement, research and evaluation, and program sustainability.

Examining Health Behaviors of Chronic Disease Caregivers in the U.S

INTRODUCTION

Many informal caregivers experience a significant caregiving burden, which may interfere with their health behaviors. Caregiver health behaviors may vary by disease context, but this has rarely been studied. This study compares the health behaviors of prevalent groups of chronic illness caregivers (i.e., dementia, cancer, chronic obstructive pulmonary disease/emphysema, diabetes) with those of noncaregivers and examines whether caregiving intensity is associated with these behaviors.

METHODS

In 2021, using pooled cross-sectional 2015-2019 Behavioral Risk Factor Surveillance System data, health behaviors (i.e., physical activity, diet, alcohol use, smoking, sleep, and influenza immunization) of caregivers of patients with dementia (n=5,525), cancer (n=4,246), chronic obstructive pulmonary disease/emphysema (n=1,959), and diabetes (n=2,853) and noncaregivers (n=203,848) were compared. Relationships between caregiving intensity (e.g., hours, type of tasks) and caregiver health behaviors were examined. Regression analyses were used to compare groups.

RESULTS

Compared with noncaregivers, caregiver groups were more likely to report engaging in both risky (i.e., smoking, shorter sleep duration) and health-promoting (i.e., physical activity, vegetable consumption, abstaining from heavy drinking) behaviors, whereas nonsignificant differences were observed for influenza immunization. Longer caregiving hours and providing help with personal care were associated with poorer health behaviors (e.g., shorter sleep duration). Few differences in health behaviors were observed between caregivers of patients with dementia and other caregiver groups.

CONCLUSIONS

Results suggest that caregivers are more likely to engage in both risky and health-promoting behaviors than noncaregivers. Furthermore, findings suggest that greater caregiving responsibilities are associated with certain risky health behaviors. Findings support the development and implementation of strategies to improve caregivers' health behaviors across disease contexts.

To Help or Not to Help? Prosocial Behavior, Its Association With Well-Being, and Predictors of Prosocial Behavior During the Coronavirus Disease Pandemic

The coronavirus disease (COVID-19) pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants (N = 9,496) from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions.

The Impact of Caregiving Intensity and Religiosity on Spousal Caregivers' Health and Mortality in the US (2004-2014)

OBJECTIVES

Despite adverse physical and mental health outcomes related to caregiving, family caregivers also experience lower mortality rates compared to noncaregivers. However, research has not yet examined the role of caregiving intensity and religiosity with health and mortality among spousal caregivers.

METHODS

Data include spousal caregivers (n=5,214 person-wave observations) and noncaregivers (n=50,311 person-wave observations) from the Health and Retirement Study (2004-2014 waves). Multinomial logistic regression was used to explore how caregiving intensity and religiosity were associated with health and mortality among spousal caregivers, compared health and mortality between caregivers and noncaregiving peers, and examined gender differences in these mechanisms.

RESULTS

Greater religious salience and attending religious services, although dependent on gender and caregiving intensity, are protective for caregivers' health and mortality.

DISCUSSION

Religiosity may buffer adverse effects of caregiving on health and mortality for spousal caregivers. Continuation of prior religiosity may enhance positive aspects of caregiving and decrease caregiver burden.

Baby Boomers Who Provide Informal Care for People Living with Dementia in the Community

One in four Baby Boomers fills the informal caregiver role in the United States. The objectives of this study were to estimate the prevalence of Baby Boomers who are informal caregivers for people living with dementia and compare their physical and mental health status to caregivers for persons with conditions other than dementia using 2015–2018 Behavioral Risk Factor Surveillance System data (N = 10,602). We identified caregiving status (assisting a family member/friend with a long-term illness or disability in the past month, managing personal care, and not caring for a child/grandchild) and whether the care recipient’s major health condition was dementia. We calculated weighted estimates and used chi-square tests and log-binomial regression for comparisons of selected characteristics. Among Baby Boomer caregivers, 15.4% were caring for someone with dementia. Dementia caregivers were more likely to be female, caring for a parent/parent-in-law, and providing care longer than caregivers for persons without dementia. After adjusting for sociodemographic and caregiving characteristics, the prevalence of fair/poor health, frequent mental distress, and chronic conditions were similar across types of caregivers. Although no differences in caregiver’s physical and mental health by care recipient’s dementia status were found, we should underscore the importance of maintaining Baby Boomer caregivers’ health and well-being.

Demographics and stress as risk factors associated with mortality in older adults who provide daily support and who receive daily support

ABSTRACT Objective: Despite the greater vulnerability of care providers, the literature shows that their mortality rate is considerably lower compared to care recipients. The aim of the present study was to analyze the mortality rates of community-dwelling older adults who provided support in activities of daily living (ADL) (group PC) and older adults who received in activities of daily living (group RC) in a four-year period considering the effects of age, sex and schooling in both groups and stress in in group PC. Methods: 261 older adults PC and 279 older adults RC participated in the study. In 2014, we collected data on demographic characteristics and functioning. In 2018, the participants were contacted a second time and information on deaths was obtained. The mortality rate was calculated for each group. Results: Death cases in four years were considerably higher among the group who were receiving support. The mortality rate was 12.6% in the PC group and 31.2% in the RC group. In deceased PC, 69% presented with high-perceived stress in baseline. About half of the PC were independent, whereas the RC group exhibited some functional dependence in 2014. There was no association between risk factors in the group PC, however the female sex was marginally associated with the risk of mortality among the RC (HR: 1.7 [95% CI: 0.9-3.0]). Conclusion: Some demographic characteristics have been considered risk factors for the mortality of the old age population, however these were not confirmed in this study among the older adults who provided and received care.

Association Between New-Onset Medicaid Home Care and Family Caregivers' Health

Importance

More than 17 million people in the US provide uncompensated care for adults with physical or cognitive limitations. Such caregiving is associated with worse mental and physical health, yet little research has investigated how publicly funded home care might ameliorate these harms.

Objective

To investigate the association between Medicaid home care services and family caregivers' health.

Design Setting and Participants

This longitudinal cohort study used data from the 1996 to 2017 Medical Expenditures Panel Survey. Data on all household members were collected in 5 interviews over 2 years. Person-level difference-in-difference models were used to isolate within-person changes associated with new onset of Medicaid home care. The Medical Expenditures Panel Survey longitudinal data sets included 331 202 individuals (approximately 10% excluded owing to loss to follow-up). Adult (age ≥21 years) members of households that contained at least 1 person with limited activities of daily living were included in our study. The analysis itself was performed from March to August of 2020.

Exposures

New onset of regular (≥1 time per month) Medicaid home care in the household.

Main Outcomes and Measures

Self-rated mental and physical health (planned prior to beginning the study).

Results

The study population was 14 013 adults; 7232 were "likely caregivers," or nondisabled adult coresidents of someone with activities of daily living limitations. Overall, 962 likely caregivers were ever exposed to Medicaid home care in the household; for 563, we observed the onset. Of likely caregivers exposed to Medicaid home care, 479 (50%) were women; 296 (31%) were White non-Hispanic, 309 (31%) were Hispanic or Latinx, and 279 (29%) were Black non-Hispanic individuals, respectively; 326 (34%) had less than a high school education; and 300 (31%) were in or near poverty. Median age of participants was 51 (interquartile range, 39-62) years. New-onset Medicaid home care was associated with a 0.08 standard deviation improvement in likely caregivers' self-rated mental health (95% CI, 0.01-0.14; P = .02) measured 1 to 6 months after onset, equivalent to a 3.39% improvement (95% CI, 0.05%-6.33%) over their average preonset mental health. No association with self-rated physical health was found (<0.001 standard deviations; 95% CI, -0.06 to 0.06; P = .99).

Conclusions and Relevance

In this cohort study, Medicaid home care was associated with improvement in caregiver self-rated mental health, but not with any short-term change in self-rated physical health. When evaluating the social value of home care programs, policy makers should consider spillover benefits to caregivers.

Stress, Burden, and Well-Being in Dementia and Nondementia Caregivers: Insights From the Caregiving Transitions Study

BACKGROUND AND OBJECTIVES

Few population-based studies have directly compared caregivers of persons with dementia to caregivers of persons with other disabilities (nondementia caregivers). We enrolled dementia and nondementia caregivers who were providing substantial and sustained care and compared these groups on measures of caregiver stressors, appraisals of burden, and well-being.

RESEARCH DESIGN AND METHODS

Caregivers (N = 251) who provided continuous care for at least 1 year and at least 5 h per week were recruited from the population-based REasons for Geographic And Racial Differences in Stroke (REGARDS) study. Caregivers reported on dementia caregiving status, stressors, burden, and well-being.

RESULTS

Forty-seven percent (n = 117) reported caring for a person with dementia. Dementia caregivers reported more stressors, providing more care for self-care and behavioral problems than nondementia caregivers. Dementia caregivers also reported higher appraisals of stress and burden, and more depressive symptoms, but did not differ from nondementia caregivers on mental and physical health quality of life. In multivariable-adjusted models, adjustment for the total number of care recipient problems attenuated differences between dementia and nondementia caregivers on burden and depression measures.

DISCUSSION AND IMPLICATIONS

Dementia and nondementia caregivers showed relatively few differences in indicators of overall well-being in this population-based sample, perhaps because both groups of caregivers in this study were providing substantial care. Dementia caregivers may require special assistance with dementia-specific problems such as behavioral problems. Clinical interventions and policy changes targeting highly burdened caregivers are needed to support them in allowing their care recipients to age in place at home.

The balance of giving versus receiving social support and all-cause mortality in a US national sample

While numerous studies exist on the benefits of social support (both receiving and giving), little research exists on how the balance between the support that individuals regularly give versus that which they receive from others relates to physical health. In a US national sample of 6,325 adults from the National Survey of Midlife Development in the United States, participants were assessed at baseline on hours of social support given and received on a monthly basis, with all-cause mortality data collected from the National Death Index over a 23-y follow-up period. Participants who were relatively balanced in the support they gave compared to what they received had a lower risk of all-cause mortality than those who either disproportionately received support from others (e.g., received more hours of support than they gave each month) or disproportionately gave support to others (e.g., gave many more hours of support a month than they received). These findings applied to instrumental social support (e.g., help with transportation, childcare). Additionally, participants who gave a moderate amount of instrumental social support had a lower risk of all-cause mortality than those who either gave very little support or those who gave a lot of support to others. Associations were evident over and above demographic, medical, mental health, and health behavior covariates. Although results are correlational, one interpretation is that promoting a balance, in terms of the support that individuals regularly give relative to what they receive in their social relationships, may not only help to strengthen the social fabric of society but may also have potential physical health benefits.

Associations between spousal caregiving and health among older adults in Mexico: A targeted estimation approach

OBJECTIVE

To evaluate associations between spousal caregiving and mental and physical health among older adults in Mexico.

METHODS

Data come from the Mexican Health & Aging Study, a national population-based study of adults ≥50 years and their spouses (2001-2015). We compared outcomes for spousal caregivers to outcomes for those whose spouses had difficulty with at least one basic or instrumental activity of daily living (I/ADL) but were not providing care; the control group conventionally includes all married respondents regardless of spouse's need for care. We used targeted maximum likelihood estimation to evaluate the associations with past-week depressive symptoms, lower-body functional limitations, and chronic health conditions.

RESULTS

At baseline, 846 women and 629 men had a spouse with ≥1 I/ADL. Of these, 60.9% of women and 52.6% of men were spousal caregivers. Spousal caregiving was associated with more past-week depressive symptoms for men (Marginal Risk Difference (RD): 0.27, 95% confidence internal [CI]: 0.03, 0.51) and women (RD: 0.15, 95% CI: 0.07, 0.23). We could not draw conclusions about associations with lower-body functional limitations and chronic health conditions. On average, all respondents whose spouses had caregiving needs had poorer health than the overall sample.

CONCLUSION

We found evidence of an association between spousal caregiving and mental health among older Mexican adults with spouses who had need for care. However, our findings suggest that older adults who are both currently providing or at risk of providing spousal care may need targeted programs and policies to support health and long-term care needs.

Do Informal Caregivers Expect to Die Earlier? A Longitudinal Study with a Population-Based Sample on Subjective Life Expectancy of Informal Caregivers

INTRODUCTION

Subjective life expectancy is a good predictor of health and could therefore be a relevant factor in the informal caregiving context. However, no research has been conducted on the perception of life expectancy by informal caregivers. This is the first study that examines the association between transitioning into, and out of, informal caregiving, and subjective life expectancy, and the relevance of employment status and gender for these associations.

METHODS

A longitudinal study was conducted with data from the German Ageing Survey (waves 2008, 2011, 2014, and 2017). Up to 20,774 observations pooled over all waves were included in the main models. In total, 1,219 transitions into and 1,198 transitions out of informal caregiving were observed. Fixed effects (FE) regression analysis was used. Moderator and stratified analyses were conducted with gender and employment status used as moderator variables and to stratify the sample. Sociodemographic information, health, and lifestyle factors were controlled for.

RESULTS

Results of adjusted FE regression analyses indicated a significant reduction of subjective life expectancy when transitioning into informal caregiving. No significant change was found when transitioning out of informal caregiving. Subjective life expectancy was significantly decreased when employed individuals transitioned into informal caregiving and significantly increased when they transitioned out of caregiving. Findings for women transitioning into informal caregiving indicated a significant decrease in subjective life expectancy, while no significant change was found among men.

CONCLUSION

The study's findings indicate that informal caregivers, female and employed caregivers in particular, perceive informal care provision as dangerous for their longevity and expect to die earlier when transitioning into informal caregiving. Thus, supportive interventions for informal caregivers, particularly employed and female informal caregivers, are recommended.

Association Between Caregiver Strain and Self-Care Among Caregivers With Diabetes

IMPORTANCE

Caregiver strain has been shown to be associated with adverse effects on caregivers' health, particularly among those with cardiovascular disease. Less is known about the association of caregiver strain with health behaviors among caregivers with diabetes, a disease that requires a high degree of self-care.

OBJECTIVE

To examine the association between caregiver strain and diabetes self-care among caregivers with diabetes.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted between July 13, 2018, and June 25, 2020, using data on 795 US caregivers aged 45 years or older with self-reported diabetes from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, which comprised 30 239 Black and White adults 45 years or older throughout the US enrolled from January 2003 to October 2007.

EXPOSURES

Caregiver strain, assessed by self-report in response to the question, "How much of a mental or emotional strain is it to provide this care?" Response options were no strain, some strain, or a lot of (high) strain.

MAIN OUTCOMES AND MEASURES

Diabetes self-care, which was assessed across 4 domains (Mediterranean diet adherence, physical activity, smoking status, and medication adherence), and a composite self-care score summing performance across these domains. The association between caregiver strain and diabetes self-care was examined with multivariable Poisson regression adjusting for demographic, clinical, physical and mental functioning, and caregiving covariates.

RESULTS

Among the 795 caregivers with diabetes included in the study, the mean (SD) age was 63.7 (8.6) years, 469 (59.0%) were women, and 452 (56.9%) were Black individuals. Overall, 146 caregivers (18.4%) reported high caregiver strain. In unadjusted models, high caregiver strain was associated with less physical activity (prevalence ratio [PR], 0.66; 95% CI, 0.45-0.97), low medication adherence (PR, 0.80; 95% CI, 0.68-0.94), and worse self-care (PR, 0.65; 95% CI, 0.44-0.98). In adjusted models, the association between some and high caregiving strain with low medication adherence remained significant (adjusted PR: some strain, 0.88 [95% CI, 0.78-0.99]; high strain, 0.83 [95% CI, 0.69-0.99]).

CONCLUSIONS AND RELEVANCE

In this cohort study of US adult caregivers with diabetes, a high level of strain was associated with low medication adherence. Increased awareness of the prevalence of caregiver strain and potential ramifications on caregivers' self-care appears to be warranted among health care professionals and caregivers.

All-cause mortality for cohabiting spouses of stroke survivors: Evidence from Swedish national registries

BACKGROUND/OBJECTIVES

Spousal concordance for cardiovascular risk factors and lifestyle behaviors may affect prevalence rates of diabetes, hypertension, and stroke. Spouses of stroke survivors, therefore, would be expected to have elevated mortality rates, but this has not been established. Thus, the aim of this study was to investigate whether cohabitant spouses of stroke survivors have higher mortality rates compared to a matched reference cohort.

METHODS

Data for this population-based cohort study were extracted from Swedish national registries from 2010 to 2016. The national sample consisted of 13,049 spouses of first ever stroke survivors and a reference cohort of 51,685 cohabitant individuals from the general population matched by age, gender, and place of residence. Effects on mortality were analyzed using Cox proportional hazard survival analyses.

RESULTS

Female and male spouses of stroke survivors were found to have 5-year hazard ratios of death of 1.26 (95% confidence interval 1.17, 1.36) and 1.24 (95% confidence interval 1.16, 1.33), respectively, when compared to the reference cohort. Both female and male spouses had higher mortality from diseases in the circulatory system compared to the reference cohort.

CONCLUSION

Spouses of stroke survivors have higher mortality rates than a matched reference population that persist for a minimum of 5 years. Policy-makers should acknowledge and address the health status of spouses when evaluating and planning the health and social care of stroke survivors.

Age-dependency in mortality of family caregivers: a nationwide register-based study

Background

Evidence on family caregivers' health is conflicting.

Aim

To investigate all-cause and cause-specific mortality in Finnish family caregivers providing high-intensity care and to assess whether age modifies the association between family caregiver status and mortality using data from multiple national registers.

Methods

The data include all individuals, who received family caregiver's allowance in Finland in 2012 (n = 42,256, mean age 67 years, 71% women) and a control population matched for age, sex, and municipality of residence (n = 83,618). Information on dates and causes of death between 2012 and 2017 were obtained from the Finnish Causes of Death Register.

Results

Family caregivers had lower all-cause mortality than the controls over the follow-up (8.1 vs. 11.6%) both among women (socioeconomic status adjusted hazard ratio [HR]: 0.64, 95% CI 0.61–0.68) and men (adjusted HR: 0.73, 95% CI 0.70–0.77). When modelling all-cause mortality as a function of age, younger caregivers had only slightly lower or equal mortality to their controls, but older caregivers had markedly lower mortality than their controls, up to more than 10% lower. Caregivers had a lower mortality rate for all the causes of death studied, namely cardiovascular, cancer, neurological, external, respiratory, gastrointestinal and dementia. The lowest risk was for dementia (subhazard ratio = 0.29, 95% CI 0.25–0.34).

Conclusions

Older family caregivers had lower mortality than the age-matched general population while mortality did not differ according to caregiver status in young adulthood. This age-dependent advantage in mortality is likely to reflect the selection of healthier individuals into the family caregiver role.

Till Death Do Us Part: Intersecting Health and Spousal Dementia Caregiving on Caregiver Mortality

OBJECTIVE

We consider whether it is the healthiest dementia caregivers who experience a mortality benefit and whether a protective association is consistent for leading causes of mortality.

METHOD

Using the Health and Retirement study (2000-2012), Cox survival models predict time to death for dementia caregivers, including an interaction between dementia caregiver status and self-rated health. The nationally representative sample consisted of 10,650 married adults aged 51 or older (917 dementia caregivers).

RESULTS

A significant interaction between dementia caregiver status and self-rated health suggested that relative to noncaregivers, dementia caregivers had reduced mortality, with this effect particularly strong at lower levels of self-rated health. The protective effect of dementia caregiver status was consistent across death by heart disease, cancer, and cerebrovascular disease.

DISCUSSION

These findings add to a growing body of literature suggesting that caregiving may provide a mortality benefit and a reason to maintain health.

The transition to family caregiving and its effect on biomarkers of inflammation

Chronic stress has been widely proposed to increase systemic inflammation, a pathway that may link stress with a heightened risk for many diseases. The chronic stress-inflammation relationship has been challenging to study in humans, however, and family caregiving has been identified as one type of stressful situation that might lead to increased inflammation. Previous studies of caregiving and inflammation have generally used small convenience samples, compared caregivers with poorly characterized control participants, and assessed inflammation only after caregivers provided care for extended periods of time. In the current project, changes over a 9-y period were examined on six circulating biomarkers of inflammation for 480 participants from a large population-based study. All participants reported no involvement in caregiving prior to the first biomarker assessment, and 239 participants then took on extensive and prolonged family caregiving responsibilities at some point prior to the second biomarker assessment. Incident caregivers were individually matched on multiple demographic and health history variables with participants who reported no caregiving responsibilities. Of the six biomarkers examined, only tumor necrosis factor alpha receptor 1 showed a significantly greater increase in caregivers compared with controls. This effect was small (d = 0.14), and no effects were found for a subset of 45 caregivers who were living with a spouse with dementia. These results are consistent with recent meta-analytic findings and challenge the widespread belief that caregiving is a substantial risk factor for increased inflammation. Future research is warranted on factors that may account for stress resilience in family caregivers.

Caregiving Intensity and Mortality in Older Women, Accounting for Time-Varying and Lagged Caregiver Status: The Caregiver-Study of Osteoporotic Fractures Study

BACKGROUND AND OBJECTIVES

Caregiving is associated with reduced mortality in recent studies. Investigations of caregiving intensity may reveal an underlying mechanism. However, studies of caregiving intensity and mortality have mixed results, perhaps due to imprecise measurement of caregiving intensity, not accounting for healthier persons likely having greater caregiving involvement, or temporal changes in intensity. We examined the relationship between caregiving intensity (based on tasks performed) and mortality, treating intensity and health status as time-varying, and lagging exposure.

RESEARCH DESIGN AND METHODS

Caregiving tasks among 1,069 women in the Caregiver-Study of Osteoporotic Fractures study (35% caregivers) were assessed at 5 interviews conducted between 1999 and 2009. Caregivers were categorized as high intensity if they assisted a person with dressing, transferring, bathing, or toileting; or as low intensity if they assisted with other instrumental or basic activities of daily living (I/ADLs). Alternatively, high intensity was defined as assisting with more than the median number of I/ADL tasks (median-based measure). Mortality was assessed through 2011. Cox proportional hazards models estimated adjusted hazard ratios (aHR) and 95% confidence intervals based on concurrent intensity, and lagging exposure 2 years.

RESULTS

High-intensity caregivers had significantly lower mortality using the median-based measure after lagging exposure (aHR = 0.55, 0.34-0.89). Similar, but not statistically significant associations were observed in non-lagged analyses (aHR = 0.54, 0.29-1.04) and task-specific intensity (aHRs were 0.61 and 0.51). Low-intensity caregivers had similar mortality rates to noncaregivers in all analyses.

DISCUSSION AND IMPLICATIONS

Among older women, high-intensity caregivers had lower mortality rates than noncaregivers. Whether this association extends to other populations merits investigation.

Effect of reduced formal care availability on formal/informal care patterns and caregiver health: a quasi-experimental study using the Japanese long-term care insurance reform

BACKGROUND

It is unclear how formal long-term care (LTC) availability affects formal /informal caregiving patterns and caregiver health. We tested the impact of reduced formal LTC availability on formal LTC service use, intensity of informal caregiving, and caregiver health.

METHODS

Using a representative, repeated cross-sectional sample of Japanese caregivers providing care to co-resident family members from 2001 to 2016, we applied a difference-in-differences approach by observing caregivers before and after the major reform of the public Japanese LTC insurance (LTCI) in 2006. The reform reduced coverage benefits for non-institutionalized older persons with low care needs, but not for those with high care needs. We analyzed 12,764 caregivers aged ≥30 years (mean age 64.3 ± 11.8 years, 73.5% women) and measured indicators of formal LTC use, hours of informal caregiving, and caregiver self-reported health outcomes after propensity score matching to balance caregivers' background characteristics.

RESULTS

We found the 2006 LTCI reform relatively reduced the use of formal LTC services and relatively increased the percentage of experiencing long hours of informal caregiving (> 3 h per day) among the caregivers for seniors with low care needs compared to those for seniors with high care needs. The effects of the LTCI reform for the caregivers for seniors with low care needs were 2.2 percentage point higher on caregivers' experiencing poor self-rated health (95% confidence interval [CI]: 0.7-3.7; p = 0.01), 2.7 percentage point higher on experiencing symptoms of a depressive state (95%CI: 0.5-4.8; p = 0.03), and 4.7 percentage point higher on experiencing symptoms of musculoskeletal diseases (95%CI, 3.6-5.7; p < 0.001), compared to those for seniors with high care needs.

CONCLUSIONS

Reduced formal care availability under the Japanese LTCI reform increased hours of informal caregiving corresponding to reduced use of formal LTC and deteriorated multiple dimensions of caregiver health. Our findings may highlight the importance of enhancing the availability of formal LTC services for caregiver health.

The association between informal caregiving and behavioral risk factors: a cross-sectional study

Objectives

This study aimed to compare informal caregivers/dementia caregivers to non-caregivers regarding alcohol consumption, smoking behavior, obesity, and insufficient physical activity and to identify caregiving-related factors (caregiving intensity, length of caregiving, relationship to the care recipient, and type of caregiving task) which are associated with behavioral risk factors in caregivers/dementia caregivers.

Methods

Using cross-sectional data from the Behavioral Risk Factor Surveillance System, we performed the statistical analyses applying logistic regression models and accounted for confounding using the entropy balancing approach.

Results

For caregivers (n = 12,044), the odds of overweight/obesity and smoking were higher (OR = 1.14/1.34, p < 0.05) and the odds of binge drinking and insufficient physical activity were lower (OR = 0.86/0.83, p < 0.05) than for non-caregivers (n = 45,925). For dementia caregivers, results point in the same direction. Caregiving-related variables tend to influence the likelihood of behavioral risk factors, but depending on the kind of factor considered, in different directions.

Conclusions

Being a caregiver is associated with risky and health-promoting behavior. However, the effects are relatively low. Future studies should study potential pathways between caregiving characteristics, psychological impacts of caregiving, health behavior, and mental or physical health.

The emotional and mental health needs of young carers: what psychiatry can do

AIMS AND METHOD

To review the literature on the emotional and mental health needs of young carers of parents with mental illness and the extent to which such needs are recognised and supported by professionals. Three databases were systematically searched from 2008 to 2018, and five studies met the inclusion criteria.

RESULTS

The key findings were that young caregivers had a significantly higher dose-response mortality risk than their peers; were at increased risk of mental health difficulties, especially where the ill family member was a parent and had mental illness or misused substances; were overlooked by professionals owing to a lack of awareness; but could derive benefits from their caring role when appropriately supported.

CLINICAL IMPLICATIONS

Young carers are at increased risk regarding emotional and mental health needs; this risk could be mitigated by professionals recognising the young carer's role and including them in their parent's treatment plan.

Informal caregiving and physical activity among 204,315 adults in 38 low- and middle-income countries: A cross-sectional study

Data on the association between informal caregiving and physical activity (PA) levels are scarce, especially from low- and middle-income countries (LMICs). Furthermore, previous research has yielded conflicting results. Thus, we investigated this association in adults from 38 LMICs. Data from the World Health Survey (WHS), a cross-sectional, predominantly nationally representative survey conducted in 2002-2004, were analyzed. PA was assessed by the International Physical Activity Questionnaire and participants were dichotomized into those who do (≥150 min of moderate-to-vigorous PA per week) and do not (<150 min = low PA) comply with the World Health Organization PA recommendations. Those who provided help to a relative or friend (adult or child), because this person has a long-term physical or mental illness or disability, or is getting old and weak in the past year were considered to be informal caregivers. Multivariable logistic regression analysis was conducted to assess the associations. There were 204,315 adults aged ≥18 years from 38 LMICs included in this study [mean (standard deviation) age 38.6 (16.1) years; 50.7% female]. Overall, the prevalence of caregiving and low PA was 19.5% and 29.9%, respectively. After adjustment for potential confounders, caregivers were at a lower risk for low PA compared to non-caregivers (OR = 0.79; 95% CI = 0.72-0.86). Engagement in greater number of caregiving activities was associated with lower odds for low PA dose-dependently. Informal caregiving was associated with higher levels of PA in adults in LMICs. Future studies of longitudinal design are warranted to understand causality and the underlying mechanisms of this association.

The Relation Between Multiple Informal Caregiving Roles and Subjective Physical and Mental Health Status Among Older Adults: Do Racial/Ethnic Differences Exist?

PURPOSE OF THE STUDY

The present study examined whether race/ethnicity moderated the relation between type of caregiving role (none, one, or multiple care recipients) and subjective physical and mental health among older adults.

DESIGN AND METHODS

The sample was drawn from the 2009 California Health Interview Survey. Racially/ethnically diverse adults aged 55 and older (n = 24,241) were categorized into 3 groups by caregiving roles: noncaregivers (n = 18,626; referent), caregivers with a single caregiving role (n = 4,023), and caregivers with multiple caregiving roles (n = 1,772). A 2-way analysis of covariance was conducted to test main and interaction effects.

RESULTS

After adjustment for covariates, noncaregivers reported significantly worse self-rated health and lower psychological distress than caregivers with any type of role. The interaction between race/ethnicity and caregiving roles was significant only for self-rated health (p < .05). Blacks with multiple caregiving roles had poorer self-rated health than those with a single caregiving role and better self-rated health than noncaregivers, whereas other racial/ethnic groups with multiple caregiving roles had better self-rated health compared to both noncaregivers and those with a single caregiving role. Our sensitivity analysis showed that controlling caregiving-related variables present only among caregivers eliminated the differences in self-rated health between the two types of caregivers.

IMPLICATIONS

Findings suggest that caregivers report better self-rated health than noncaregivers and that the relation of multiple caregiving roles with self-rated health differs by race/ethnicity, with blacks differing from other racial/ethnic groups. This implies that caregivers experience gain, or are selected into the role of caregiving by virtue of having good health.

Caregiver Reactions to Aggressive Behaviors in Persons With Dementia in a Diverse, Community-Dwelling Sample

Purpose: To describe caregiver challenges with and confidence managing three aggressive behavior types in persons with dementia: verbal aggression, destroying property, and threatening to hurt others. Design and Method: Secondary analysis of baseline data from the 2001-2004 Resources for Enhancing Alzheimer's Caregiver Health II (REACH II) initiative. Results: One or more aggressive behaviors within 1 week were reported by more than a third of caregivers, with most expressing upset but fewer expressing confidence managing the behaviors. Caregiver distress and confidence differed by race/ethnicity in response to verbal aggression, with more White/Caucasian caregivers expressing upset than Hispanic/Latinos or Black/African Americans. Fewer Hispanic/Latinos expressed confidence managing verbal aggression, compared with White/Caucasians or Black/African Americans. Discussion: Aggressive behaviors challenge caregivers, with reactions varying by behavior type and race/ethnicity. Cultural and contextual factors suggest the need to tailor interventions, especially skill-building interventions that increase confidence managing aggressive behaviors while decreasing upset.

Informal Caregiving and All-Cause Mortality: A Meta-Analysis of Longitudinal Population-Based Studies

Using the random-effects meta-analysis model, we investigated the effect of informal caregiving on all-cause mortality across 12 longitudinal population-based studies (seven United States; five international: United Kingdom, Northern Ireland [2], Japan, and Australia). Across the studies, the combined effect of informal caregiving on all-cause mortality was 16% lower in favor of caregivers. Subgroup analyses revealed that the relationship between informal caregiving and all-cause mortality was not significant among the U.S. studies, in contrast to the international studies. Also, the mortality advantage of informal caregivers was not evident among those studies in which informal caregiving was operationalized precisely (Activity of Daily [ADL]/Instrumental Activity of Daily Living [IADL] assistance) as opposed to more broadly. Furthermore, studies in which the kinship tie between the informal caregiver and care recipient was unspecified tended to find a mortality advantage in favor of caregivers. When covariates were considered, the results of this meta-analysis provided more support for stress theory than the healthy caregiver hypothesis.

Assessing the Role of Selection Bias in the Protective Relationship Between Caregiving and Mortality

Caregivers have lower mortality rates than noncaregivers in population-based studies, which contradicts the caregiver-stress model and raises speculation about selection bias influencing these findings. We examined possible selection bias due to 1) sampling decisions and 2) selective participation among women (baseline mean age = 79 years) in the Caregiver-Study of Osteoporotic Fractures (Caregiver-SOF) (1999-2009), an ancillary study to the Study of Osteoporotic Fractures (SOF). Caregiver-SOF includes 1,069 SOF participants (35% caregivers) from 4 US geographical areas (Baltimore, Maryland; Minneapolis, Minnesota; the Monongahela Valley, Pennsylvania; and Portland, Oregon). Participants were identified by screening all SOF participants for caregiver status (1997-1999; n = 4,036; 23% caregivers) and rescreening a subset of caregivers and noncaregivers matched on sociodemographic factors 1-2 years later. Adjusted hazard ratios related caregiving to 10-year mortality in all women initially screened, subsamples representing key points in constructing Caregiver-SOF, and Caregiver-SOF. Caregivers had better functioning than noncaregivers at each screening. The association between caregiving and mortality among women invited to participate in Caregiver-SOF (41% died; adjusted hazard ratio (aHR) = 0.73, 95% confidence interval (CI): 0.61, 0.88) was slightly more protective than that in all initially screened women (37% died; aHR = 0.83, 95% CI: 0.73, 0.95), indicating little evidence of selection bias due to sampling decisions, and was similar to that in Caregiver-SOF (39% died; aHR = 0.71, 95% CI: 0.57, 0.89), indicating no participation bias. These results add to a body of evidence that informal caregiving may impart health benefits.

Transitions to family caregiving: enrolling incident caregivers and matched non-caregiving controls from a population-based study

BACKGROUND AND AIM

Providing care to an older adult with a disability has been associated with increased risk to the caregiver's health, but most previous studies of caregiving and health compare persons who are already caregivers with poorly matched non-caregiving controls and are often based on convenience samples. In this report, we describe the enrollment of persons who transitioned into a family caregiving role while participating in a national epidemiological study.

METHODS

Participants in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study were asked on two occasions 9-14 years apart if they were providing care on an ongoing basis to a family member with a chronic illness or disability. Those who answered "no" and "yes", respectively, to this caregiving question and reported sufficient caregiving responsibilities after their transitions were enrolled in the present study as incident caregivers (N = 251). Participants matched on multiple demographic and health history variables and who reported no history of caregiving were enrolled as non-caregiving controls (N = 251).

RESULTS

Among eligible participants, 84% agreed to participate, and 47% of caregivers reported caring for a person with dementia. Descriptive analyses confirmed the success of the matching procedures for balancing the groups on multiple demographic and pre-caregiving health variables. Depressive symptoms and perceived stress increased significantly after the transition to caregiving.

CONCLUSION

Comparable, population-based samples of incident caregivers and matched non-caregivers have been enrolled. Future analyses will examine within-person changes in health and circulating biomarkers as a function of the transition to caregiving.

Are volunteering and caregiving associated with suicide risk? A Census-based longitudinal study

BACKGROUND

Opposing risks have been identified between different prosocial activities, with volunteering having been linked to better mental health while caregiving has been associated with higher prevalence and incidence of depression. This study explored suicide risk of people engaged in prosocial activities of caregiving and/or volunteering.

METHODS

A Census-based record linkage study of 1,018,000 people aged 25-74 years (130,816 caregivers; 110,467 volunteers; and 42,099 engaged in both) was undertaken. Caregiving (light: 1-19; intense: ≥20 h/week), volunteering and mental health status were derived from 2011 Census records. Suicide risk (45 months follow-up) was assessed using Cox models adjusted for baseline mental health.

RESULTS

Intense caregiving was associated with worse mental health (OR_adj = 1.15: 95%CI = 1.12, 1.18) and volunteering with better mental health (OR = 0.87: 95%CI = 0.84, 0.89). For those engaged in both activities, likelihood of poor mental health was determined by caregiving level. There were 528 suicides during follow-up, with those engaged in both activities having the lowest risk of suicide (HR = 0.34: 95%CI = 0.14, 0.84). Engaging in either volunteering or caregiving was associated with lower suicide risk for those with good mental health at baseline (HR = 0.66: 95%CI = 0.49, 0.88) but not for their peers with baseline poor mental health (HR = 1.02: 95%CI = 0.69, 1.51).

CONCLUSIONS

Although an increased risk of poor mental health was identified amongst caregivers, there was no evidence of an increased risk of suicide.

Unmet needs of family cancer caregivers predict quality of life in long-term cancer survivorship

PURPOSE

To identify demographic and caregiving characteristics associated with caregivers' unmet needs and to examine associations of caregivers' unmet needs with their quality of life at 2 years and 5 years since their patients' initial diagnosis.

METHODS

Family cancer caregivers completed prospective longitudinal surveys at 2 years (T1) and 5 years (T2) post diagnosis. Demographic and caregiving characteristics were measured at T1. Unmet needs and quality of life were measured at T1 and T2.

RESULTS

Younger and spousal caregivers reported greater unmet needs (B > 2.03, p < .05). Independent of demographic characteristics, caregivers' perception that providing care to their relative with cancer was overwhelming was consistently associated with unfulfillment of their needs in various domains, concurrently and prospectively (B > 2.50, p < .05), across the long-term survivorship phases.

CONCLUSIONS

Findings highlight the contribution of earlier subjective caregiving stress to family caregivers' needs not being met both currently and years later, which, in turn, related to poorer quality of life across different family caregivership trajectories. Findings suggest identifying at-risk subgroups of family caregivers based on demographics and assessing caregiving stress as a priority in psycho-oncology research and clinical practices.

IMPLICATIONS FOR CANCER SURVIVORS

Family caregivers' quality of life is affected by cancer survivors' illness trajectory many years after the initial cancer diagnosis, so are the caregivers' needs. Cancer survivorship care plan should take careful consideration of the nuanced long-term contributions of caregivers' unmet needs to their specific aspects of quality of life.

Impact of Caregiving for Dementia Patients on Healthcare Utilization of Caregivers

The elderly, whom are vulnerable to the physical, mental and chronic diseases of aging, are the fastest growing segment of the US population. Dementia is of particular concern in this population, and caregivers of people with dementia are subjected to psychological, physical, emotional and functional stress. The purpose of this study was to investigate the impact of caregiving for dementia patients on health care services utilization of caregivers and to examine if caregivers utilize more healthcare services than the control group. The study recruited a total of 143 people in control and non-control groups through non-probability convenience sampling. The control group (non-caregivers) comprised of 71 people, whereas the experimental group (caregivers) consisted of 72 participants. The focus of the study was the health care utilization questionnaire, asking the caregiver about the frequency of specific health care services utilization-including medication use in the last six months, on the scale from 0 to 10. Results were statistically significant for each of the healthcare service utilization when comparing caregivers to the control group. By providing adequate support and assistance in form of support groups, we can alleviate caregivers' burden and more effectively address the needs of caregivers-thereby reducing the utilization of healthcare services.

Is Family Caregiving Associated With Inflammation or Compromised Immunity? A Meta-Analysis

BACKGROUND AND OBJECTIVES

Family caregiving stress has been widely reported to have negative effects on circulating biomarkers of immune system function and inflammation. Our goals were to systematically review this literature and conduct a meta-analysis on the extracted effects.

RESEARCH DESIGN AND METHODS

A systematic search of published studies comparing caregivers and noncaregivers on biomarkers measured from blood samples was conducted in the PubMed, Embase, and Cochrane databases. This search identified 2,582 articles and abstracts. After removing duplicative papers and studies not meeting inclusion criteria, 30 articles were identified that reported analyses on 86 relevant biomarkers from 1,848 caregivers and 3,640 noncaregivers.

RESULTS

Random-effects models revealed an overall effect size across all biomarkers of 0.164 SD units (d). A slightly larger overall effect (d = 0.188) was found for dementia caregivers only. Immune system comparisons yielded somewhat larger differences than inflammation comparisons. Most studies used small convenience samples, and effect sizes were larger for studies with moderate or high bias ratings than for studies with low bias ratings. No significant associations were found in studies that used population-based samples.

DISCUSSION AND IMPLICATIONS

Caregivers had small but significantly reduced immune system functioning and greater inflammation than noncaregivers, but associations were generally weak and of questionable clinical significance. The absence of clear associations from low bias studies and population-based studies underscores concerns with possible selection biases in many of the convenience samples. Population-based studies that assess biomarkers before and after the onset of caregiving might add much clarity to this literature.

Widening the net: exploring social determinants of burden of informal carers

OBJECTIVES

Providing care for a person with dementia or other chronic illness at home often places stress on the primary caregiver. In an Irish population, ~67% of carers reported experiencing extreme physical or mental tiredness. This study aimed to identify factors that influence carer burden and identify the sub-populations of carers who are most susceptible to burden.

METHODS

Consecutive carers referred to a local carers' support organisation completed the following measurements: the Neuropsychiatric Inventory, Zarit Burden Interview, Social Network Index, General Health Questionnaire, Short Form Survey, Hamilton Depression Rating Scale, Brown's Locus of Control scale and provided demographic data on themselves and their patient.

RESULTS

The sample consisted 53 carers, mean age: 64.5±11.7, of whom 43 (81.1%) were females. A linear regression model found significant independent (p<0.05) factors for carer burden were: increased behavioural problems of the patient, carer characteristics including female gender, younger age, high number of contacts, lower physical functioning and emotional problems, while protective factors were marriage and higher number of embedded networks.

CONCLUSIONS

The ability to predict which carers are more susceptible to burden allows service providers to more quickly and accurately identify 'higher risk' carers, facilitating routine check-ups by physicians and carer support services.

Spouse's functional disability and mortality: The Ohsaki Cohort 2006 Study

Aim

Caregiver burden is known to negatively affect a partner's health. Given the important role of physical and mental stress in mortality, a higher caregiver burden might be associated with an increased incidence of fatal events. However, previous studies of the effects of the partner's caregiving on mortality have shown inconsistent results. Thus, the purpose of the present longitudinal study was to determine if there is an association between a spouse's functional disability and mortality in the older Japanese population.

Methods

A baseline survey was carried out with 7598 participants in 2006. Information on the date of functional disability, death or emigration was retrieved from the Ohsaki City government. Functional disability was defined as receiving a certification for long‐term care insurance in Japan. After a follow‐up period of a maximum of 87 months, 1316 of the participants died and Cox regression analysis with adjustment for confounding factors was used to assess mortality after the incidence of functional disability in a spouse.

Results

The multivariate adjusted hazard ratio for mortality was 1.78 (95% confidence interval 1.52–2.08, P < 0.01) in those whose spouses had functional disabilities compared with those with spouses who did not have functional disabilities. The mortality was consistently higher, irrespective of age group or sex.

Conclusions

These results imply that caregiver burden might increase stress responses and lead to increased mortality; therefore, enhancement of support systems, including long‐term care, housing and livelihood support services, for those with disability and their spouses might be important for preventing deaths.

Innovative Tools to Support Family Caregivers of Persons with Cancer: The Role of Information Technology

OBJECTIVES

To describe the current evidence of studies examining the use of information technology for family caregivers of persons with cancer. We highlight emerging technologies and trends and discuss ethical and practical implications.

DATA SOURCES

Review scientific studies and systematic reviews of technology use to support caregivers of persons with cancer.

CONCLUSION

The evidence base is growing; however, more studies are needed to test the effectiveness of technology.

IMPLICATIONS FOR NURSING PRACTICE

Several tools have potential to provide support to family caregivers but the selection of such tools needs to address access, privacy, interoperability, and usability considerations.

Quality of life predictors in informal caregivers of seniors with a functional performance deficit - an example of home care in Poland

Background: There is insufficient research into informal caregivers' quality of life (QoL) in Poland. The purpose of this work is to study predictors that considerably affect QoL of informal caregivers (IC) providing home care for seniors with chronic diseases and a functional performance deficit. Materials and methods: In the cross-sectional research design, ICs were randomly chosen among the geriatric population receiving care in 5 primary health care settings. The WHOQoL-AGE questionnaire was used to assess QoL of ICs (n=138). The Barthel scale and Polish version of the Abbreviated Mental Test Score (AMTS) were applied to assess individuals with chronic diseases and functional and mental performance deficits (n=138). The Geriatric Depression Scale Short Form (GDS-SF) was used to measure the extent of risk of depressive symptoms in care-receivers. A hierarchical regression analysis was carried out to determine predictors of caregivers' QoL. Results: Mean values in the group of seniors provided with home care were as follows: the Barthel scale M=43.20, SD=27.06, the AMTS M=7.78 (SD=1.65), and the GDS-SF M=7.34 (SD=3.10). QoL of ICs (the WHOQoL-AGE) was M=70.14 (SD=15.31). Significant predictors of caregivers' QoL turned out to be support in care given by others β =0.605, p<0.001, experience in care β =-0.220; p<0.001, caregivers' health self-assessment β =0.174, p<0.001, and depressive disorders in care-receivers GDS β = -0.178, p<0.001. Conclusions: The QoL of ICs who provide care for individuals with chronic diseases and a functional performance deficit improves with an increase in the support they receive from others, their higher health self-assessment, and greater experience in care. An increase in depressive symptoms in care-receivers determines a lower level of caregivers' QoL.

Deactivating a Pacemaker in Home Care Hospice: Experiences of the Family Caregivers of a Terminally Ill Patient

Objectives:

Although the experiences of family members who care for relatives at the end of life have been researched extensively, little is known about the needs and experiences of families caring for hospice patients with pacemakers.

Aim:

To better understand the experiences of family caregivers of a terminally ill patient who received hospice care at home and chose deactivation of a pacemaker.

Design:

The exploratory, cross-sectional design involved semistructured, in-depth interviews. A narrative analysis focusing on form and content was chosen to analyze the data.

Participants:

Five bereaved caregivers from the Midwestern United States who provided care and participated in the deactivation of their family member’s pacemaker.

Results:

Four storylines that described, gave meaning to, and contextualized the caregivers’ experiences were identified: “I am done. I am not doing it anymore”; “Whatever you decide, I’ll support you”; “It is really difficult to watch, but you want to be there”; and “I will not have part of this.” Caregivers struggled with lack of support, understanding, and acceptance from medical providers when their family member decided to have her pacemaker deactivated, and they believed that the hospice model of care was appropriate to support and help them in that process.

Conclusions:

This research aids in understanding the ramifications of family-provided end-of-life care to a patient whose pacemaker has been deactivated. This can help to increase hospice clinicians’ knowledge regarding caregivers’ experiences facing deactivation of a pacemaker, before and after the patient’s death.

Health Benefits Associated With Three Helping Behaviors: Evidence for Incident Cardiovascular Disease

Objective

The purpose of this study was to investigate the association between three helping behaviors and incident cardiovascular disease (CVD; heart attack, stroke; fatal and nonfatal), with an exploration of gender differences. The study is framed within the caregiving system model. Helping others is argued to be an evolved characteristic of humans that yields beneficial health effects.

Methods

Data were taken from the 2004-2014 waves of the Health and Retirement Study. The three forms of helping others considered were formal volunteering, informal helping, and caregiving for a parent or spouse. Cox proportional hazards models were estimated for gender-stratified samples.

Results

Women who volunteered showed a lower risk of incident CVD compared to women who did not volunteer. Men who informally helped others in the community exhibited a lower risk of incident CVD compared to men who did not provide this form of help. Caregiving status was generally not associated with incident CVD for women or men.

Discussion

The results demonstrated that specific types of prosocial behavior may be beneficial for women and men. However, tests for effect differences showed that gender did not moderate the relationships between these helping behaviors and CVD risk.

Neural response to prosocial scenes relates to subsequent giving behavior in adolescents: A pilot study

Adolescence is characterized by extensive neural development and sensitivity to social context, both of which contribute to engaging in prosocial behaviors. Although it is established that prosocial behaviors are linked to positive outcomes in adulthood, little is known about the neural correlates of adolescents' prosociality. Identifying whether the brain is differentially responsive to varying types of social input may be important for fostering prosocial behavior. We report pilot results using new stimuli and an ecologically valid donation paradigm indicating (1) brain regions typically recruited during socioemotional processing evinced differential activation when adolescents evaluated prosocial compared with social or noninteractive scenes (N = 20, ages 13-17 years, M_Age = 15.30 years), and (2) individual differences in temporoparietal junction recruitment when viewing others' prosocial behaviors were related to adolescents' own charitable giving. These novel findings have significant implications for understanding how the adolescent brain processes prosocial acts and for informing ways to support adolescents to engage in prosocial behaviors in their daily lives.
