Impact of long-hours family caregiving on non-fatal coronary heart disease risk in middle-aged people: Results from a longitudinal nationwide survey in Japan

Paid Leave to Meet the Health Needs of Aging Family Members in 193 Countries

Women and workers over 50 disproportionately provide care for aging family members worldwide, including the 101 million who are care-dependent. Paid leave for adult health needs, which temporarily replaces employment income for workers providing care, can critically support both caregivers' economic outcomes and care recipients' wellbeing. We created quantitatively comparable data on paid leave policies that can be used to meet adult family members' health needs in all United Nations member states. Globally, 112 countries fail to provide any paid leave that can be used to meet the serious health needs of an aging parent, spouse, or adult child. These gaps have profound consequences for older workers providing care as well as care access by aging, ill, and disabled adults.

Impact of caregiving on mental, self-rated, and physical health: evidence from the China health and retirement longitudinal study

OBJECTIVES

Given the escalating demand for care services, understanding the impact of informal caregiving, providing unpaid care for family members, on own health is essential. This study longitudinally analyzed the association of caregiving (and different caregiver types) with mental, physical, and self-rated health. Urban-rural, gender, and employment heterogeneity were further investigated.

METHOD

Based on three-wave data (2011, 2013, and 2018) from the China Health and Retirement Longitudinal Study, we used growth curve models to assess the impact of informal caregiving (providing care to family members) and caregiver types (caregivers to grandchildren, parents, spouses, or multiple family members) on three health outcomes (depressive symptoms, self-rated health, and activities of daily living limitations).

RESULTS

Our study included 13,377 individuals. Results showed a negative correlation of caregiving with mental, physical, and self-rated health. Compared to noncaregivers, spousal caregivers and multiple caregivers were both associated with worsening mental, self-rated, and physical health. In contrast, adult child caregivers were only negatively associated with mental health, and grandparent caregiving did not significantly affect any health outcomes. Further heterogeneity analysis showed that gender did not moderate the relationship between caregiving and health, whereas the negative association between caregiving and health was more pronounced among the rural population and those employed in agriculture.

DISCUSSION

Findings from the present study suggest that caregiving is detrimental to health, and recommend considering caregiver type when examining caregiving and health. These findings have vital implications for policymakers in addressing the challenges of structuring and implementing a sustainable informal care system.

Impact of Residential Segregation on Healthcare Utilization and Perceived Quality of Care Among Informal Caregivers in the United States

This study aimed to investigate the impact of racial residential segregation on healthcare utilization and perceived quality of care among informal caregivers in the US. It further assessed potential variations in the estimated impact across caregivers' race and socioeconomic status. We used data from the Health Information National Trends Survey Data Linkage Project (fielded in 2020) for a sample of 583 self-identified informal caregivers in the US. Fitting a series of regression models with the maximum likelihood estimation, we computed the beta coefficients (β) of interest and their associated Wald 95% confidence limits (CI). Caregivers who resided in areas with higher segregation, compared to those living in lower segregated areas, were less likely to visit a healthcare professional [β =  - 2.08; Wald 95%CI - 2.093, - 2.067] (moderate); [β =  - 2.53; Wald 95%CI - 2.549, - 2.523] (high)]. Further, caregivers residing in moderate [β =  - 0.766; Wald 95%CI - 0.770, - 0.761] and high [β =  - 0.936; Wald 95%CI - 0.941, - 0.932] segregation regions were less likely to perceive a better quality of care compared to those located in low segregation areas. Moreover, as segregation level increased, Black caregivers were less likely to see a health professional, less frequently used healthcare services, and had poorer perceived healthcare quality when compared to Whites. Our findings indicate that higher residential segregation is associated with lower healthcare utilization, such as visiting a healthcare professional, and poorer perceived healthcare quality among informal caregivers. Given the essential role of informal caregivers in the current healthcare system, it is vital to investigate and address challenges associated with access to and quality of essential healthcare services to improve caregivers' health and well-being, specifically for caregivers of minority backgrounds.

Association of disrupted sleep with 24-hour blood pressure variability in caregivers

BACKGROUND

A growing body of research highlights the negative impact of caregiving on cardiovascular disease (CVD) risk.

OBJECTIVES

This study aimed to examine associations of psychological symptoms and sleep quality with 24-hour blood pressure variability (BPV), which is an independent predictor of CVD, among family caregivers of community-dwelling individuals with chronic illness.

METHODS

For this cross-sectional study, we assessed caregiving burden and depressive symptoms using questionnaires and 7-day sleep quality (i.e., number of awakenings, wake after sleep onset, sleep efficiency) using an actigraph. The participants carried out a 24-hour ambulatory BP monitoring for systolic and diastolic BPV over 24 h and during awake/sleep times. We performed Pearson's correlations and multiple linear regression.

RESULTS

The analytic sample consisted of 30 caregivers (25 female; mean age 62 years). The number of awakenings during sleep was positively correlated with systolic BPV-awake (r = 0.426, p = 0.019) and diastolic BPV-awake (r = 0.422, p = 0.020). Sleep efficiency was negatively correlated with diastolic BPV-awake (r = -0.368, p = 0.045). Caregiving burden and depressive symptoms were not correlated with BPV. After controlling for age and mean arterial pressure, the number of awakenings was significantly associated with increased systolic BPV-24 h (β = 0.194, p = 0.018) and systolic BPV-awake (β = 0.280, p = 0.002), respectively.

CONCLUSIONS

Caregivers' disrupted sleep may play a role in increased CVD risk. While these findings should be confirmed in large clinical studies, improving sleep quality would need to be considered in CVD prevention for caregivers.

A systematic review comparing cardiovascular disease among informal carers and non-carers

Exposure to chronic stress increases the risk of cardiovascular disease (CVD). Providing informal care is known to be a stressful activity, but it is not clear whether informal caregiving is associated with CVD risk. This systematic review aimed to summarise and assess the quantitative evidence examining the association between providing informal care to others and CVD incidence in comparison with non-carers. Eligible articles were detected by searching six electronic literature databases (CINAHL, Embase, Global Health, OVID Medline, Scopus, and Web of Science). Two reviewers appraised 1887 abstracts and 34 full-text articles against a set of a priori eligibility criteria to identify articles for inclusion. Quality assessment of included studies was performed using the ROBINS-E risk of bias tool. Nine studies were identified that quantitatively assessed the association between providing informal care and CVD incidence in comparison to not providing informal care. Overall, there was no difference in the incidence of CVD between carers and non-carers across these studies. However, within the subgroup of studies that examined care provision intensity (hours/week) higher CVD incidence was observed for the most intense caregiving group compared to non-carers. One study examined only CVD-related mortality outcomes, observing a reduction in mortality for carers compared to non-carers. More research is required to explore the relationship between informal care and CVD incidence.

Last Aid Course—The Slovenian Experience

Educating and raising awareness among lay members of the public about palliative care can significantly improve the care for terminally ill patients and their quality of life. This paper reports on the survey aimed at assessing the experience and expectations of participants in the Last Aid course launched in Slovenia in 2019 to train hospice volunteers and promote dialogue on death and dying. The course implementation was supported by materials prepared, translated, and/or adapted from German under the PO-LAST project, which linked Slovenian medical and healthcare professionals, hospice representatives, and university students. The Last Aid course follows an international four-module curriculum that has been successfully applied in 18 countries so far. In Slovenia, the course was delivered 30 times with 21 in-person deliveries and 9 online events attended by 450 participants of different sexes, ages, and professions. The surveyed population included 250 people who returned the evaluation questionnaires by October 2020. The aim of the analysis was to gain insight that can be applied broadly in future work and research on adult education on palliative care and the erasure of death-related taboos.

Family caregiving and changes in mental health status in Japan during the COVID-19 pandemic

Background

The coronavirus disease 2019 (COVID-19) pandemic has had a widespread significant impact on mental health. However, the effect of providing care to family members (informal caregiving) on changes in mental health status during the pandemic remains unclear.

Methods

Using cross-sectional data from a large internet survey conducted between August and September 2020, we investigated the association of informal caregiving status with the incidence of mental health deterioration (increased loneliness, self-reported deterioration in mental health, and new suicidal ideation) in Japan during the COVID-19 pandemic.

Results

Among 25,482 participants (mean age 48.8 [standard deviation 17.3]; 50.3% women), 2,500 (9.8%) were providing informal care during the pandemic. After adjusting for potential confounders, informal caregivers were more likely than non-caregivers to experience increased loneliness (adjusted odds ratio [aOR] 2.16; 95% confidence interval [CI] 1.70–2.76), self-reported deterioration in mental health (aOR 1.54; 95% CI 1.14–2.08), and new incidence of suicidal ideation (aOR 3.65; 95% CI 1.92–6.92). The degree of mental health deterioration depended on the intensity of care. For example, the incidence rates of new suicidal ideation were 15.0%, 5.2%, and 3.6% for individuals who provided high-intensity caregiving, those who provided low-intensity caregiving, and non-caregivers, respectively (p-for-trend<0.001). The stratified analysis by gender showed that informal caregiving was associated with self-reported deterioration in mental health status among women (aOR 2.19; 95% CI 1.49–3.21) but not men (aOR 1.08; 95% CI 0.75–1.56).

Conclusion

Informal caregivers were more likely to experience mental health deterioration than non-caregivers during the COVID-19 pandemic.

Care needs level in long-term care insurance system and family caregivers' self-perceived time-dependent burden in patients with home palliative care for cancer: a cross-sectional study

PURPOSE

Although home care improves patients' quality of life (QOL), several studies have suggested that home care lowers the QOL of family caregivers and decreases their mortality. To alleviate the deleterious impact of home care on caregivers, the major burdens on caregivers and the clinical characteristics of the caregivers vulnerable to the major burden needs to be clarified.

METHOD

A survey questionnaire was distributed to 710 family caregivers of patients with cancer in Japan, and 342 valid responses were obtained (valid response rate: 48.2%). The Burden Index of Caregivers was used to identify the major burden on caregivers. To assess the associations of the patients' care needs level and other clinically relevant factors with the major burden, a multivariable-adjusted logistic regression model was used.

RESULTS

The time-dependent burden was identified as a major burden. An adjusted model showed a nonlinear association between the care needs level and the time-dependent burden, in which the caregivers of the patients who required moderate care needs level had the highest time-dependent burden [adjusted odds ratio of none, mild, moderate, and severe care needs levels: 0.50 (95% confidence interval 0.07-2.12), 1.08 (0.43-2.57), 1.87 (1.01-3.52), and 1.00 (reference), respectively]. Additionally, older patients and younger caregivers were significantly associated with a time-dependent burden.

CONCLUSION

The time-dependent burden was highest in caregivers at the moderate care needs level and younger caregivers. An imbalance between the demand and supply of care services may be improved by considering the clinical characteristics of both patients and caregivers.

Cardiovascular Disease Incidence and Risk in Family Caregivers of Adults With Chronic Conditions: A Systematic Review

BACKGROUND

Family caregivers experience psychological distress or physical strain that may lead to an increased risk of cardiovascular disease (CVD) morbidity and mortality.

OBJECTIVE

This systematic review aimed to describe the current evidence and gaps in the literature on measures used to assess CVD outcomes in family caregivers, the association of caregiving with CVD incidence/risk outcomes, and associated factors in family caregivers of patients with chronic disease.

METHODS

Medline, PubMed, CINAHL, Web of Science, and Google Scholar were searched for English-language, peer-reviewed studies published from 2008 to 2020 that examined CVD incidence and risk among family caregivers of adults with chronic conditions.

RESULTS

Forty-one studies were included in this review. The measures used to assess CVD risk were categorized into biochemical, subclinical markers, components of metabolic syndrome, and global risk scores. Compared with noncaregivers, caregivers were more likely to have higher CVD incidence rates and objectively measured risk. Cardiovascular disease risks were also increased by their caregiving experience, including hours/duration of caregiving, caregivers' poor sleep status, psychological symptoms, poor engagement in physical/leisure activities, and care recipient's disease severity.

CONCLUSIONS

Although there were limited longitudinal studies in caregivers of patients with diverse health conditions, we found evidence that caregivers are at high risk of CVD. Further research for various caregiver groups using robust methods of measuring CVD risk is needed. Caregiver factors should be considered in developing interventions aimed at reducing CVD risk for caregivers.

Effects of Psychosocial Interventions and Caregiving Stress on Cardiovascular Biomarkers in Family Dementia Caregivers: The UCSD Pleasant Events Program (PEP) Randomized Controlled Trial

BACKGROUND

This study examined whether biological mechanisms linking dementia caregiving with an increased risk of coronary heart disease can be modified by psychosocial interventions and which caregivers might benefit the most from an intervention.

METHODS

Spousal dementia caregivers were randomized to 12-week treatment with either a behavioral activation intervention (ie, Pleasant Events Program [PEP]; n = 60), or an active control Information and Support (IS; n = 63) condition. Indicators of caregiving stress were assessed pretreatment and circulating cardiovascular biomarkers were measured pre- and posttreatment.

RESULTS

There were no significant changes in biomarker levels from pre- to posttreatment both by treatment condition and across all caregivers. Regardless of the treatment condition, exploratory regression analysis revealed that caregivers were more likely to show significant decreases in C-reactive protein (CRP) and D-dimer when their spouse had severe functional impairment; in interleukin (IL)-6 and CRP when they had greater distress due to care recipient's problem behaviors; in tumor necrosis factor (TNF)-α when they had higher levels of negative affect; and in IL-6, CRP, TNF-α, and D-dimer when they had higher personal mastery. Within the PEP group, caregivers with higher negative affect and those with higher positive affect were more likely to show a reduction in von Willebrand factor and D-dimer, respectively. Within the IS group, caregivers whose spouse had severe functional impairment were more likely to show a decrease in IL-6.

CONCLUSIONS

Unlike the average caregiver, caregivers high in burden/distress and resources might benefit from psychosocial interventions to improve cardiovascular risk, although these observations need confirmation.

The Influence of Family Caregivers' Experience of Interprofessional Care on Their Participation in Health Checkups as Preventive Health Behavior in Japan-A Cross-Sectional Analysis

Background: The role of family caregivers has been vital, especially in superaging societies like Japan’s. The caregivers’ experience of interprofessional care is a key aspect in their evaluation of the quality of integrated care. We sought to explore whether family caregivers’ experience of interprofessional care is associated with their own participation in health checkups as preventive health behaviors. Methods: We used cross-sectional data obtained during the development of the Japanese version of the Caregivers’ Experience Instrument (J-IEXPAC CAREGIVERS). Participants who had provided care for at least one year were surveyed (n = 251). We assessed family caregivers’ experience of interprofessional care using J-IEXPAC CAREGIVERS and their participation in health checkups. Results: Multivariate logistic regression analysis revealed that the J-IEXPAC CAREGIVERS total score was significantly associated with the caregivers’ participation in health checkups [odds ratio per 1-point increase = 1.05; 95% confidence interval 1.01–1.09]. Two domain scores (attention for the patient and attention for the caregiver) of J-IEXPAC CAREGIVERS were significantly associated with the outcome. Conclusions: Family caregivers with more positive experiences of interprofessional care were more likely to participate in health checkups. These results support the significance of family caregivers’ experience of care, which may promote preventive health behaviors.

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.

The impact of receiving informal care on self-esteem and its moderation by social class

Objectives: This longitudinal study aims to investigate the association between informal care receipt and self-esteem, and explore the influence of social class on this association.Method: Data from the German Ageing Survey (waves 2002, 2008, 2011, 2014; 7870 observations) drawn from community-dwelling individuals (aged 40 years and older) was used.Results: Results revealed that receiving care was not significantly associated with self-esteem. However, when the sample was stratified by social class, receipt of care was significantly associated with increased self-esteem in individuals from lower social classes (lower class, lower middle class). Moderator analysis demonstrated a significant interaction effect between belonging to the lower middle class and receipt of care.Conclusion: Our results demonstrate that care recipients can benefit from informal care regarding their self-esteem, at least if they are from lower social classes. This implies that informal care should be supported.

Relationships between informal caregiving, health and work in the Health and Employment After Fifty study, England

BACKGROUND

To investigate the prevalence of caregiving and its relationship with work, health and socio-economic circumstances in the Health and Employment After Fifty (HEAF) study.

METHODS

The HEAF study comprises 8134 men and women aged 50-64 years recruited from 24 general practices. Socio-demographic, lifestyle and health characteristics and hours per week giving personal care were elicited by postal questionnaire. Objective clinical information about diagnoses/medications was retrieved from health records. Work-related and health risk factors for intense caring responsibilities (≥20 h/week vs. no hours) were explored using logistic regression with adjustment for age and social class.

RESULTS

In all, 644 (17%) men and 1153 (26%) women reported caring responsibilities, of whom 93 and 199 were intense caregivers, who were more likely to be socio-economically disadvantaged; less likely to be working and, if combining caring with working (41 men and 90 women), more likely to be part-time/working shifts, than non-carers. Men caring ≥20 h/week were more likely to have COPD and to report musculoskeletal pain, poor/fair self-rated health, depression and sleep problems. Among working women, caring ≥20 h/week was associated with these same health outcomes and also with a doctor-diagnosed mental health problem or musculoskeletal pain in the previous year.

CONCLUSIONS

Caregiving is common and unequal in the HEAF cohort, with more high-intensity informal care provided by those with greater levels of socio-economic deprivation, which could affect their employment and health. Caregivers need support to lead long, healthy lives, rather than becoming care needers themselves. Employers and governments need to take caregiving into account and support it actively.

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 activities of daily living and long hours of care provided by informal caregivers using a nationally representative survey in Japan

•We determined the relationship between long hours of care and the assistance in each activity of daily living (ADL) element.•The assistance in wiping of the body, dressing and toileting were significantly associated with longer hours of care .•To support caregivers effectively, it is important to consider the kinds of ADL elements of the care recipients.

Parental caregiving trajectories and Metabolic Syndrome: A longitudinal study among Chinese women

Caregiving stress may play a role in the pathogenesis of Metabolic Syndrome (MetS). However, few studies have investigated the consequences of caregiving on this objectively measured health outcome. This study used population based longitudinal data to examine the causal relationship between caregiving trajectory and MetS among Chinese women. This is a retrospective analysis of 741 women using three waves of data from the Ever-Married Women Survey component of the China Health and Nutrition Survey (2004, 2006, and 2009). Group-based trajectory analysis was used to examine the caregiving trajectories among women in China. Three caregiving trajectories were identified. In multivariate analyses adjusting for potential covariates, 'rising to high-intense' caregivers (Odds Ratio (OR) = 3.78; 95% Confidence Interval (CI): 1.10, 12.93) and 'stable low-intense' caregivers (OR = 2.07; 95% CI: 1.09, 3.92) were associated with higher risk of MetS compared with non-caregivers. Moreover, caregivers who provided 'stable low-intense' parental care were found to be associated with hypertension, high glucose and high triglycerides than those awho did not provide caregiving for their parents. Our results demonstrate that the caregiving trajectories were significantly associated with the risk of MetS. Findings from the study can be used to develop future stress management interventions to decrease MetS risk among women who provide care to their parents.

Differences in risk factors and chronic conditions between informal (family) carers and non-carers using a population-based cross-sectional survey in South Australia

BACKGROUND

There is growing discussion on the impact of informal caregiving on the health status and morbidity of family carers. Evidence suggests a proportion of carers may be at risk of poor health outcomes. However, there are limited population-based studies that provide representative data on specific risk factors among carers (eg, blood pressure, cholesterol, smoking status, activity and body mass index) and major chronic conditions (eg, asthma, diabetes and arthritis). This study aimed to redress that imbalance.

METHOD

Self-reported data were from the South Australian Monitoring and Surveillance System (SAMSS), a representative cross-sectional state-wide population-based survey of 600 randomly selected persons per month. SAMSS uses computer-assisted telephone interviewing (CATI) to monitor chronic health-related problems and risk factors and to assess health outcomes. In total, 2247 family carers were identified from 35 195 participants aged 16 years and older for the 5-year period from 2010 to 2015. Logistic regression analyses examined associations of being a carer with self-reported chronic diseases and health risk factors. In addition, the population attributable risk (PAR) of being a carer was examined for selected chronic conditions.

RESULTS

The prevalence of carers was 6.4%, and peak age group for carers was 50-59 years. Adjusted ORs for chronic conditions in carers were significant for all chronic conditions examined. Although there is a high prevalence of self-reported risk factors and chronic conditions among carers compared with non-carers at the population level, PAR findings suggest that caregiving is associated with a small to moderate increased risk of having these chronic conditions.

CONCLUSIONS

Monitoring of carer health and morbidity particularly 'at risk' individuals such as female carers with asthma or diabetes remains important and provides an ongoing baseline for future surveys. To achieve this, caregiver-based studies need to become part of mainstream biomedical research at both epidemiological and clinical levels.
