Longitudinal analysis of multiple indicators of health decline among spousal caregivers

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.

[The impact of caregiving on the emotional well-being and health of family caregivers.]

INTRODUCTION

Family caregivers, who take care of older relatives, bear a heavy burden that can detrimentally affect their physical health and emotional well-being.

OBJECTIVE

This study aims to explore the subjective perceptions of family caregiving's impact on physical health and emotional well-being, the experience of feeling overburdened by caregiving responsibilities, and the subjective perceptions of health among caregivers of older relatives. Data from three waves of online questionnaire surveys conducted in 2018, 2020, and 2022 were analyzed.

METHOD

The COPE Index items were used to measure subjective perceptions of the impact of caregiving on physical health and emotional well-being and perceptions of being overburdened by caregiving. We present descriptive statistics and chi-square test analyses.

RESULTS

In all three waves, the majority of respondents frequently or always perceived a negative impact of caregiving on their emotional well-being and physical health, with more than half always or often experiencing caregiver overburdening. A significant correlation was observed between the perceived impact of caregiving on physical health and emotional well-being, over 70% of respondents provided similar responses to both questions. Furthermore, a significant relationship is between the prevalence of caregiver overburden and subjective perceptions of health, with those experiencing caregiver overload being more likely to report poor or very poor health. Over 60% of participants indicated frequent or constant overburden of care, with this subgroup exhibiting a higher likelihood of perceiving their health as poor or very poor.

DISCUSSION

Our results demonstrate that the caregiving burden affects both physical and emotional well-being. A significant proportion of family caregivers experience detrimental effects on their physical health and emotional well-being due to caregiving responsibilities. These negative effects were reported simultaneously by the majority of respondents.

CONCLUSION

Caregiving can have negative consequences on the health of family caregivers. Our research underscores the importance of preventive measures. Orv Hetil. 2023; 164(40): 1583-1591.

A burden shared: the financial, psychological, and health-related consequences borne by family members and caregivers of people with cancer in India

In India, approximately 1.4 million new cases of cancer are recorded annually, with 26.7 million people living with cancer in 2021. Providing care for family members with cancer impacts caregivers' health and financial resources. Effects on caregivers' health and financial resources, understood as family and caregiver "financial toxicity" of cancer, are important to explore in the Indian context, where family members often serve as caregivers, in light of cultural attitudes towards family. This is reinforced by other structural issues such as grave disparities in socioeconomic status, barriers in access to care, and limited access to supportive care services for many patients. Effects on family caregivers' financial resources are particularly prevalent in India given the increased dependency on out-of-pocket financing for healthcare, disparate access to insurance coverage, and limitations in public expenditure on healthcare. In this paper, we explore family and caregiver financial toxicity of cancer in the Indian context, highlighting the multiple psychosocial aspects through which these factors may play out. We suggest steps forward, including future directions in (1) health services research, (2) community-level interventions, and (3) policy changes. We underscore that multidisciplinary and multi-sectoral efforts are needed to study and address family and caregiver financial toxicity in India.

The Differential Effects of Caregiving Intensity on Overnight Hospitalization

This study aims to examine how caregiving for a spouse affects caregivers' likelihood of overnight hospitalization. Using data from the Health and Retirement Study, we examine the odds of spousal caregivers experiencing an overnight hospitalization in the previous two years according to caregiving status, intensity, and change in caregiving intensity. Caregivers were no more likely to experience an overnight hospitalization than noncaregivers (OR = .92; CI [.84, 1.00]). Effects varied by intensity of care. Compared to noncaregivers, caregivers who reported providing no assistance with activities of daily living were less likely to experience overnight hospitalization (OR = .77; CI [.66, .89]); however, caregivers who provided care to someone living with dementia for 4 to <6 years had 2.11 times the odds of experiencing an overnight hospitalization (CI [1.16, 3.85]). Although caregivers overall experience overnight hospitalization at a similar rate as noncaregivers, there are differences between caregivers by the intensity of care.

Spousal caregiving, widowhood, and cognition: A systematic review and a biopsychosocial framework for understanding the relationship between interpersonal losses and dementia risk in older adulthood

Accumulating research suggests that stressful life events, especially those that threaten close intimate bonds, are associated with an increased risk of dementia. Grieving the loss of a spouse, whether in the form of caregiving or after the death, ranks among 'life's most significant stressors', evoking intense psychological and physiological distress. Despite numerous studies reporting elevated dementia risk or poorer cognition among spousal caregivers and widow(er)s compared to controls, no review has summarized findings across cognitive outcomes (i.e., dementia incidence, cognitive impairment rates, cognitive performance) or proposed a theoretical model for understanding the links between partner loss and abnormal cognitive decline. The current systematic review summarizes findings across 64 empirical studies. Overall, both cross-sectional and longitudinal studies revealed an adverse association between partner loss and cognitive outcomes. In turn, we propose a biopsychosocial model of cognitive decline that explains how caregiving and bereavement may position some to develop cognitive impairment or Alzheimer's disease and related dementias. More longitudinal studies that focus on the biopsychosocial context of caregivers and widow(er)s are needed.

Systematic review of the effectiveness of caregiver training with functional mobility tasks for informal caregivers assisting patients with neurological diagnoses

PURPOSE

To complete a systematic review to identify evidence of the effectiveness of informal caregiver training with functional mobility tasks for patients with neurological diagnoses routinely completed by physical therapists (PTs).

METHODS

Databases searched: PubMed, PEDro, CINAHL, Web of Science, Proquest Health and Medical, and Scopus. Authors included studies with adult patients requiring assistance with functional mobility due to a neurological diagnosis, with the care provided by informal caregivers. Authors excluded studies with paid caregivers, or patient diagnoses of human immunodeficiency virus, dementia, or cancer. Data extracted included type of study, methodological quality review (using Downs and Black scale), number of subjects, outcome measures, interventions, and main results.

RESULTS

Of 2372 total articles screened, 36 full-text articles were analyzed, with seven articles identified for inclusion in the review. All studies showed variability in number of subjects, methods, interventions, outcome measures, and results. Four of the studies showed positive results from the training of informal caregivers.

CONCLUSIONS

While there is initial evidence that training informal caregivers in physical mobility tasks may help to lessen caregiver burden, further investigation is warranted. The topics typically addressed by PTs with informal caregiver training, such as transfers and ambulation, have not been extensively studied in the literature.Implications for rehabilitationPhysical therapists routinely complete training for caregivers on functional mobility tasks, with some initial evidence of the effectiveness of this training.Training for informal caregivers assisting individuals with neurological conditions has the potential to reduce injuries and decrease caregiver burden.Rehabilitation professionals should implement effective training methods for caregivers, resulting in a safer home environment for individuals with neurological diagnoses.

Factors associated with informal caregiving and its effects on health, work, and social activities of adult informal caregivers in Malaysia: findings from the National Health and Morbidity Survey 2019

BACKGROUND

The increase in the elderly population, chronic and degenerative diseases, as well as accidents at work and on the road in Malaysia would result in an increased demand for informal care. This paper aimed to determine the associated factors of informal caregiving and its effects on health, work and social activities of adult informal caregivers in Malaysia.

METHODS

The data from the 2019 National Health and Morbidity Survey (NHMS), a nationwide cross-sectional survey with a two-stage stratified random sampling design, was used in this research. The study included respondents who were 18 years and older (n = 11,674). Data were obtained via face-to-face interviews using validated questionnaires. Descriptive and complex sample logistic regression analyses were employed as appropriate.

RESULTS

5.7% of the adult population were informal caregivers. Provision of informal care were significantly associated with the female sex (OR = 1.52, 95% CI [1.21, 1.92]), those aged 36-59 years (OR = 1.61, 95% CI [1.15, 2.25]), and those who reported illness in the past 2 weeks (OR = 1.79, 95% CI [1.38, 2.33]). The risk of having their health affected were associated with female caregivers (OR = 3.63, 95% CI [1.73, 7.61]), those who received training (OR = 2.10, 95% CI [1.10, 4.00]) and those who provided care for 2 years or more (OR = 1.91, 95% CI [1.08, 3.37]). The factors associated with the effects on work were ethnicity, received training and had no assistance to provide the care. In terms of effect on social activities, female caregivers (OR = 1.96, 95% CI [1.04, 3.69]) and caregivers who received training were more likely (OR = 2.19, 95% CI [1.22, 3.93]) to have their social activities affected.

CONCLUSION

Our study revealed that sex, age, and self-reported illness were factors associated with being an informal caregiver in Malaysia. Informal caregivers faced effects on their health, work, and social activities which may be detrimental to their well-being. This understanding is crucial for planning support for caregivers.

Health Literacy of Osteoporosis Risks among Caregivers Serving in Disability Care Facilities

Osteoporosis is a global public health issue and its consequent effects are a growing concern worldwide. Caregivers generally experience occupational physical ailments and they have less of a tendency to engage in preventive health behaviors, leading them to be in a higher risk group for osteoporosis. This study aims to present a general profile of health literacy related to osteoporosis risks and identify its associated factors among disability institutional caregivers. A cross-sectional study with a structured questionnaire was used to collect information on 465 caregivers from seven disability care institutions regarding their awareness of the health literacy related to osteoporosis risks. The results indicate that the average literacy score related to osteoporosis risks among the respondents was 60 points (full score is 80 points), with 50–59 being the most common range (51.9%), followed by 60–69 points (43.5%), and 4.4% of cases had more than 70 points. A multivariate logistic regression model revealed that respondents’ age (40–49 vs. 18–29; odds ratio (OR) = 2.53, 95% confidence interval (CI) = 1.31–4.87), education level (senior high vs. primary and junior high, OR = 2.00, 95% CI = 1.03–3.89; college and above vs. primary and junior high, OR = 3.66, 95% CI = 1.84–7.31), experience in undergoing a bone density test (OR = 1.94, 95% CI = 1.28–2.93), and poor physical fitness status (OR = 0.64, 95% CI = 0.43–0.95) were the significant predictors of the osteoporosis health literacy level. The osteoporosis health literacy of institutional caregivers is moderate, and there are many items that are worthy of attention in future health promotion programs. This study highlights risk factors related to a lower level of osteoporosis healthy literacy such as older age, less education, no experience of bone density test, and poor physical fitness that highlight the need to raise further awareness in order to improve caregivers’ bone health.

An assessment of the economic burden of senile chronic diseases in China based on China Health and Retirement Longitudinal Survey

OBJECTIVE

This study assessed the economic burden of senile chronic diseases (SCD) in China.

METHODS

Based on China Health and Retirement Longitudinal Survey data, we used propensity score matching to compare the economic burden of SCD for families with and without members with SCD.

RESULTS

We examined three aspects of economic burden: health service utilization, including health care utilization and expenditure, family daily consumption spending, and workforce participation of family members in labor markets. SCD-families showed a higher hospitalization rate and number of outpatient visits than the control group. SCD-families also consumed less per capita. Additionally, the negative influence of SCD on total family income may be partially offset by increasing the labor force participation rate of healthy family members. Finally, we also discussed the burden of SCD  in different educational status.

CONCLUSIONS

Relevant results may provide insight into formulating health and labor policies by the Chinese government. The study significance consists of the selection of matching variables and robustness, whereas study limitations include the omission of other important variables.

In sickness or in health? Register-based evidence on partners' mutual receipt of sickness allowance and disability pension

Studies on partners' mutual receipt of benefits constitute a growing research field in the way individual health and health-related decisions depend on social relations. This paper provides the first study on the mutual receipt of sickness allowance. We analysed married and cohabiting couples' receipt of sickness allowance and disability pension by estimating discrete-time hazard models for individuals aged 40-65 years, using longitudinal register data from Finland. The data cover the period 1987-2011, and allowed us to explore socioeconomic and demographic variables at both the individual and couple level. We found strong and long-term interrelations in receipt behaviour and dependencies across benefit types. The risk of receiving sickness allowance increases by 50 per cent during the first years after the partner's first receipt of the same benefit, while the risk of receiving disability pension is twice as high even five years after the partner's receipt of the same. Women appear to be more instrumental than men in the production of health within the couple, even in a context of high level of state support, gender equality and female labour force participation. Their receipt of disability pension is more related to the male partner's receipt than vice versa. For sickness allowance receipt, the gender asymmetry is small. Mutual benefit receipt of benefits may relate not only to collateral health effects but also to shared preferences and partner selection. We cannot distinguish between the mechanisms. However, couples with more economic and social resources seem to be more efficient in joint decision making. Correlations are particularly strong in the immediate term, and for couples who are highly educated, for those with high income, and for those with children in the household. More effective policies may be needed to equalise information regarding benefits, and monitor the use, and potential misuse, of these health benefits.

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.

Family Economic Burden of Elderly Chronic Diseases: Evidence from China

Chronic diseases among the elderly and their huge economic burden on family have caught much attention from economists and sociologists over the past decade in China. This study measured the economic burden of elderly chronic disease (ECD) in families using the China Health and Retirement Longitudinal Study (CHARLS) data set from Peking University (China). We studied some aspects of this burden, including health-service utilization, out-of-pocket expenditure on inpatient and outpatient, total family expenditures on items, and labor force participation rates of family members, etc. Some interesting things were found, for example, the additional annual expenditure on inpatient care (per member) in ECD-families was 37 to 45 percent of the annual expenditure in the control group; the labor-force participation rate in ECD-families was 2.4 to 3.3 percent of points lower than in the control group.

Stigma, Emotion Appraisal, and the Family Environment as Predictors of Carer Burden for Relatives of Individuals Who Meet the Diagnostic Criteria for Borderline Personality Disorder

There is some research exploring carers' experiences within the National Health Service in the UK, but only one has focused on carers of individuals with borderline personality disorder (BPD). Ninety-eight carers completed a questionnaire-based study; 57 carers of individuals who meet the diagnostic criteria for BPD were compared to 41 carers of individuals with other mental health problems. The study aimed to investigate whether perceived stigma, perceived threat of strong emotions, and expressed emotion (EE) within the family environment predicted carer burden. The results showed that carers of those who met the diagnosis for BPD experienced higher levels of carer burden, stigma, EE, emotional over involvement (EOI), criticism (CC), and perceived threat of strong emotions than carers of individuals with other mental health difficulties. EOI, CC, carer group (BPD and mental health), and gender of participant were predictors of carer burden, with EOI explaining the most variance of burden.

Thiamine deficiency observed in a cancer patient's caregiver

Objective

Thiamine deficiency (TD) is recognized in various kinds of disease with associated loss of appetite including cancer; however, TD has not been recognized in the family caregivers of cancer patients to date.

Method

From a series of cancer patient caregivers, we reported an aged family caregiver who developed TD while caring for the cancer patient.

Result

The caregiver was a 90-year-old male. He had been accompanying his wife, who was diagnosed with colon cancer 4 years previously, on hospital visits as the primary caregiver, but because of psychological issues, he was recommended to visit the psycho-oncology department's “caregiver's clinic” for a consultation. Detailed examination revealed that his appetite had been only about 50% of usual from about one year before, and he had lost 12 kg in weight in one year. The diagnosis of TD was supported by his abnormally low serum thiamine level.

Significance of the results

This report demonstrates that there is a possibility that care providers could develop TD from the burdens associated with caregiving. TD should be considered whenever there is a loss of appetite lasting for more than 2 weeks, and medical staff should pay careful attention to the physical condition of care providers to prevent complications resulting from TD.

Assessment of sex analysis in studies of technology-based interventions to alleviate caregiver burden among caregivers of persons with dementia

Background

With an increase in the number of family caregivers for persons with dementia, caregiver burden is a major concern. Defined as computer-based devices and programs, technology has been identified as an intervention to address this issue. However, to date, there is little consideration of sex differences among caregivers in the design and planning of these interventions.

Objective

To systematically review the literature on technology-based interventions for caregivers of persons with dementia and report the frequency and approaches of sex-based analysis.

Methods

The literature was systematically searched for reviews of technology-based interventions for caregivers of persons with dementia. All titles and abstracts of publications included in the retrieved reviews were screened using pre-determined inclusion and exclusion criteria. Full text articles that met the inclusion criteria were included for analysis.

Results

Four reviews were identified and 19 articles representing 17 studies were retrieved. Among these studies, only four examined outcomes by sex. In the studies that examined outcomes by sex, three reported significant differences (p < 0.05) between male and female caregivers.

Conclusions

There is currently a lack of (1) sex-based analyses, (2) inclusion of males and (3) provision of sex-specific information in studies of technology-based interventions for caregivers of persons with dementia.

Association between Falls and Caregiving Tasks among Informal Caregivers: Canadian Community Health Survey Data

Falls are a common cause of morbidity and mortality in older adults. While research has explored the relationship between older care recipient falls and caregiver health, there has been little investigation of the relationship between caregiving tasks and falls in older caregivers. This study assessed associations between falls and caregiving frequency and type of caregiving tasks among informal older caregivers. Data from the Canadian Community Health Survey on Healthy Aging (Public Use Microdata File 2008-2009) (n = 2,934) were examined, using descriptive and logistic regression analyses. Higher frequency of caregiving was positively associated with falls, although those who performed household chores were less likely to report falling in the past year. Results suggest there may be an association between factors related to caregiving and falls in older caregivers. More research using longitudinal and experimental data is needed to better understand the relationship between caregiving tasks and falls in older caregivers.

Expressed Emotion in relatives of persons with dementia: a systematic review and meta-analysis

OBJECTIVES

Expressed Emotion (EE) refers to a number of key aspects of interpersonal relationships which have been shown to relate to outcomes in relatives of people with health conditions.

DESIGN

A systematic review and meta-analysis of EE and outcomes in relatives of persons with dementia is reported. Potential research studies were identified via a search of three electronic databases; PsychINFO, MEDLINE and the Web of Science between 1960 and 2015.

RESULTS

We reviewed 12 studies investigating correlations between EE and well-being in relatives of patients with dementia. Factors hypothesised to influence EE including attributions, social support, coping strategies and relationship quality were also reviewed.

CONCLUSION

High-EE relatives were found to have increased levels of burden (Z = 6.967, P < 0.001) and greater levels of depression (Z = 5.842, P < 0.001). Compared to low-EE relatives, high-EE relatives were more likely to attribute the patient's problems to factors that were personal to and controllable by the patient. Relatives with less social support, inefficient coping strategies and a poor relationship with the patients, were more likely to be classified as high-EE.

Issues in Caregivers' Stress and Providers' Support

This study examined whether support from care recipients' primary care providers affects the stress and health of caregivers. This two-year longitudinal study addressed changes in caregivers' mental and physical health, both self-assessed and evaluated by professional nurse practitioners in physical examinations, and the effects of provider support on caregivers' health. Randomly selected participants from three previous studies plus a group of volunteer Alzheimer's caregivers constituted the sample. Of 254 eligible individuals, 150 agreed to participate, but by time 2, care recipient deaths and other reasons had reduced the number of caregivers to 99. Participants showed significant increases in stress and service use but declines in all areas of health and in provider support. Provider support did not materially affect caregivers' health but had an indirect effect on caregivers' self-assessed health through rewards. Despite the need for bolstering caregivers' health, perceived support from care recipients' providers is limited.

Experiences of Family Caregiving among Middle-Aged Australian Women

Family caregiving is an unpaid activity that falls inequitably on women. As one component of the Women's Health Australia survey, this article uses quantitative and qualitative methods to examine the impact of family caregiving among middle-aged women. Of 13,888 women, 1775 responded to specific items about caregiving and 185 made openended comments about their experiences. Quantitative analyses showed that caregivers experienced more financial difficulties, poorer physical and psychological health, higher levels of stress and higher use of health care services. Content analysis of comments supported these findings, and in addition identified emerging themes including difficulties with travel, inadequacies in health and welfare systems, a sense of exploitation and fear for the future. These findings support the view that interventions to assist family caregivers must address systemic in addition to individual factors.

Correlates and Predictors of Self-reported Psychological and Physical Morbidity in Chronic Caregiver Stress

An investigation was conducted to explore: (1) whether psychological and physical morbidity share similar psychosocial determinants; (2) the long-term stability of these determinants; and (3) the role of neuroticism in predicting psychological and physical morbidity. Fifty spousal caregivers of dementia patients were recruited into a 12-month study. Participants were followed up at six-monthly interva ls during which they completed scales measuring psychosocial mediators, psychological morbidity, physical morbidity and neuroticism. Psychological morbidity was influenced primarily by indices of coping and neuroticism. Physical morbidity was influenced primarily by indices of psychological morbidity (increased psychological morbidity was associated with perceptions of greater physical morbidity). Neuroticism exhibited significant cross-sectional and longitudinal relationships with the indices of psychological morbidity, but only cross-sectional relationships with the indices of physical morbidity.

Health, Stress and Coping among Women Caregivers

Informal family-based care of dependent adults places a significant burden on caregivers. The impact of caregiving on subjective wellbeing, preventive behaviours, lifestyle and employment is well documented, and there is good evidence for increases in risk factors for serious illness, although evidence on actual incidence of major illness varies between studies. The individual-based focus of much research on this topic has tended to obscure the social and cultural forces underlying the fact that the majority of family caregivers are women, and to ignore the gender inequities which are perpetuated by an assumption that family caregiving is naturally the work of women. This article reviews evidence on the burden of caregiving, and argues for psychological research which addresses issues of public policy rather than the individual woman and her personal ability to cope.

Is Caregiving a Risk Factor for Illness?

This article focuses on the physical health of persons who provide care to family members and friends with dementia. Such caregivers are under extended chronic stress because of the particular demands that this illness places on them. Caregiver research has made important contributions in two areas of health psychology. First, this research has increased understanding of the impact of chronic illness in families. Second, it has explored the complex relationships between stress and human responses (psychological and physiological) in the context of aging, using caregiving as a prototypic chronic stressor. This article discusses the relationship between distress, health habits, physiological changes, and, ultimately, health risks. There is evidence for greater health risks in caregivers than in noncaregivers. In addition, vulnerabilities and resources influence the relationship between caregiver stressors and health. One of the greatest methodological challenges of research on caregiver health is that the studies occur under natural conditions, so that it is not possible to randomly assign people to be caregivers and then observe changes in their health. Careful designs are required to infer the reasons for health risks.

Informal and Formal Social Support and Caregiver Burden: The AGES Caregiver Survey

BACKGROUND

We examined the associations of informal (eg, family members and friends) and formal (eg, physician and visiting nurses) social support with caregiver's burden in long-term care and the relationship between the number of available sources of social support and caregiver burden.

METHODS

We conducted a mail-in survey in 2003 and used data of 2998 main caregivers of frail older adults in Aichi, Japan. We used a validated scale to assess caregiver burden.

RESULTS

Multiple linear regression demonstrated that, after controlling for caregivers' sociodemographic and other characteristics, informal social support was significantly associated with lower caregiver burden (β = -1.59, P < 0.0001), while formal support was not (β = -0.30, P = 0.39). Evaluating the associations by specific sources of social support, informal social supports from the caregiver's family living together (β = -0.71, P < 0.0001) and from relatives (β = -0.61, P = 0.001) were associated with lower caregiver burden, whereas formal social support was associated with lower caregiver burden only if it was from family physicians (β = -0.56, P = 0.001). Compared to caregivers without informal support, those who had one support (β = -1.62, P < 0.0001) and two or more supports (β = -1.55, P < 0.0001) had significantly lower burden. This association was not observed for formal support.

CONCLUSIONS

Social support from intimate social relationships may positively affect caregivers' psychological wellbeing independent of the receipt of formal social support, resulting in less burden.

Caregiving in Dementia and its Impact on Psychological Functioning and Health-Related Quality of Life: Findings from a Colombian Sample

Existing published studies about health-related quality of life (HRQOL) in caregivers of dementia patients living in Latin American countries are very limited. However, cultural aspects, personal values, and social structure may affect the way caregivers experience their role in different societies. The current study investigated the relationship between HRQOL and psychological factors using a cross-sectional design. The sample consisted of 102 informal caregivers of patients with dementia from Bogotá, Colombia, South America. Measures included the Patient Health Questionnaire (PHQ-9) for depression, the Satisfaction with Life Scale (SWLS), the Zarit Burden Interview, and the Short Health Questionnaire (SF36) for HRQOL. Canonical correlations revealed that there was a significant relationship between caregivers' mental health and HRQOL, such that caregivers with better satisfaction with life and less symptoms of depression had more vitality and better general health. There is a strong relationship between mental health and health-related quality of life in Colombian caregivers of dementia patients living in their country of origin. Specific aspects of mental health, including satisfaction with life and depression, need to be addressed in order to improve caregivers' quality of life. Given that mental health care resources may be scarce in Latin American countries, culturally appropriate interventions should focus on preventing/treating depression and promote life satisfaction, as a way to improve their quality of life.

Comparison of patient and partner quality of life and health outcomes in the first year after an implantable cardioverter defibrillator (ICD)

Recovery following an implantable cardioverter defibrillator (ICD) impacts both the patient and partner, often in divergent ways. Patients may have had a cardiac arrest or cardiac arrhythmias, whereas partners may have to perform CPR and manage the ongoing challenges of heart disease therapy. Currently, support for post-ICD care focuses primarily on restoring patient functioning with few interventions available to partners who serve as primary support. This descriptive study examined and compared patterns of change for both patients and partners during the first year post-ICD implantation. For this longitudinal study, the sample included 42 of 55 (76.4 %) patient-partner dyads who participated in the 'usual care' group of a larger intervention RCT with patients following ICD implant for secondary prevention of cardiac arrest. Measures taken at across five time points (at hospital discharge and at 1, 3, 6 and 12 months follow up) tracked physical function (SF-12 PCS, symptoms); psychological adjustment (SF-12 MCS; State-Trait Anxiety Inventory; CES-D); relationship impact (Family Functioning, DOII; Mutuality and Interpersonal Sensitivity, MIS); and healthcare utilization (ED visits, outpatient visits, hospitalizations). Repeated measures analysis of variance was used to characterize and compare outcome trends for patients and partners across the first 12 months of recovery. Patients were 66.5 ± 11.3 (mean + SD) years old, predominately Caucasian male (91 %), with Charlson co-morbidities of 4.4 ± 2.4. Partners were 62.5 ± 11.1 years old, predominantly female (91 %) with Charlson co-morbidities of 2.9 ± 3.0. Patient versus partner differences were observed in the pattern of physical health (F = 10.8, p < 0.0001); patient physical health improved while partner health showed few changes. For partners compared to patients, anxiety, depression, and illness demands on family functioning tended to be higher. Patient mutuality was stable, while partner mutuality increased steadily (F = 2.5, p = 0.05). Patient sensitivity was highest at discharge and declined; partner sensitivity increased (F = 10.2, p < 0.0001) across the 12-month recovery. Outpatient visits for patients versus partners differed (F = 5.0, p = 0.008) due most likely to the number of required patient ICD visits. Total hospitalizations and ED visits were higher for patients versus partners, but not significantly. The findings highlight the potential reciprocal influences of patient and partner responses to the ICD experience on health outcomes. Warranted are new, sound and feasible strategies to counterbalance partner needs while simultaneously optimizing patient recovery outcomes.

Health and wellbeing in informal caregivers and non-caregivers: a comparative cross-sectional study of the Swedish general population

Background

Informal caregiving by relatives is a great resource for individuals as well as for society, but the caregiving role is associated with health problems for the caregiver. This study aimed to compare caregivers’ self-rated health, number of recent days with poor health and psychological wellbeing with that of non-caregivers in a general Swedish population.

Methods

From 2004 to 2013, 90,845 Swedish people completed a postal questionnaire about their health, number of recent days with poor health during last month, psychological wellbeing and if they were performing caregiving or not. Descriptive statistics, chi-square analysis, ANOVA, logistic regressions and negative binomial regression models were used to investigate associations between being a caregiver or not and health and wellbeing. Negative binomial regression was used to assess the relation between caregiver status and recent days with poor health or functioning.

Results

Eleven percent reported having a caregiving role. Caregivers reported poorer self-rated health compered to non-caregivers, also in adjusted models; odds ratio (OR): 1.07 with a 95 % confidence interval (CI): 1.01-1.13. Caregivers also reported lower psychological wellbeing compared to non-caregivers; OR: 1.22, CI: 1.15-1.30. Caregiving status was associated with more recent days with poor physical health and more recent days with poor mental health.

Conclusions

This study suggests that caregivers have worse perceptions in self-rated health and psychological wellbeing compared with non-caregivers, indicating that the role of caregiver is adversely associated with health. This association also appears in terms of reporting days of poor health in the last month. The underlying mechanism of these associations, including the potential detrimental health effects of being a caregiver, needs to be investigated in longitudinal studies.

Drug-induced akathisia as a cause of distress in spouse caregivers of cancer patients

OBJECTIVE

Family caregivers of cancer patients suffer from physical, psychological, and social distress and therefore are often referred to as second order patients. Akathisia is a common side effect of antipsychotics and antidepressants that causes great discomfort and even agitation and is often described by patients administered these drugs as the most distressing side effect of their treatment. Several studies of akathisia as a cause of distress in cancer patients have been reported. However, akathisia has not been reported as a cause of distress in family caregivers of cancer patients.

METHOD/CASE REPORT

A 74-year-old spouse caregiver who was under treatment for major depressive disorder was not able to visit the hospital where her husband, a terminally ill cancer patient, was being treated. Initially, the spouse caregiver thought that she could not visit the hospital because of the symptoms of her depression and her grief about losing her husband. However, careful clinical examination revealed that she was suffering from akathisia in addition to her grief.

RESULTS

Discontinuation of her sulpiride treatment resulted in the disappearance of her akathisia symptoms, and therefore she became able to visit the hospital and care for her terminally ill husband.

SIGNIFICANCE OF RESULTS

Drug induced akathisia is a cause of distress in spouse caregivers taking certain drugs. It is important for clinicians to realize that family caregivers might suffer from not only socioeconomic, physical, and psychological problems but also side effects of medication.

Caregiver burden mediates between caregiver's mental health condition and elder's behavioral problems among Japanese family caregivers

OBJECTIVES

In Japan, the prevalence of depression has been reported to occur among 1 in 4 family caregivers. The purpose of this study was to investigate the self-rated burden associated with mental health conditions among caregivers.

METHODS

We studied 95 caregivers aged 38-87 years in a cross-sectional study. The General Health Questionnaire (GHQ-12) score of 4 or more was defined as poor mental health.

RESULTS

The proportion of caregivers with poor mental health was 24%. Caregivers with a high GHQ-12 score had the number of caregiver burdens increased by 2.5-fold compared to those with a low GHQ-12 score (p = 0.001). The proportion of caregivers with a high GHQ-12 score was significantly higher with an increasing number of behavioral problems among care recipients (p = 0.003). A mediational model was used to identify the underlying mechanism of the relationship between the number of behavioral problems and poor mental health in caregivers. Consequently, we found that mental health conditions in caregivers were associated with both the number of caregiver burdens and behavioral problems among care recipients.

CONCLUSIONS

It is vital to provide support not only to the caregivers but also to their elderly relatives, paying particular attention to early identification of poor mental health in caregivers so as to administer effective interventions, and to offer useful advice concerning how to deal with behavioral problems.

Lead exposure and rate of change in cognitive function in older women

BACKGROUND

Higher long-term cumulative lead exposure predicts faster cognitive decline in older men, but evidence of an association in women is lacking.

OBJECTIVE

To determine if there is an association between lead exposure and cognitive decline in women.

METHODS

This study considers a sample of 584 women from the Nurses' Health Study who live in or near Boston, Massachusetts. We quantified lead exposure using biomarkers of lead exposure assessed in 1993-2004 and evaluated cognitive decline by repeated performance on a telephone battery of cognitive tests primarily assessing learning, memory, executive function, and attention completed in 1995-2008. All cognitive test scores were z-transformed for use in analyses. We used linear mixed models with random effects to quantify the association between each lead biomarker and change in cognition overall and on each individual test.

RESULTS

Consideration of individual tests showed greater cognitive decline with increased tibia lead concentrations, a measure of long-term cumulative exposure, for story memory and category fluency. The estimated excess annual decline in overall cognitive test z-score per SD increase in tibia bone lead concentration was suggestive, although the confidence intervals included the null (0.024 standard units, 95% confidence interval: -0.053, 0.004 - an additional decline in function equivalent to being 0.33 years older). We found little support for associations between cognitive decline and patella or blood lead, which provide integrated measures of exposure over shorter timeframes.

CONCLUSIONS

Long-term cumulative lead exposure may be weakly associated with faster cognitive decline in community-dwelling women, at least in some cognitive domains.

Patterns of widowhood mortality

OBJECTIVES

Becoming widowed is a known risk factor for mortality. This article examines the magnitude of, explanations for, and variation in the association between widowhood and mortality. Previous research on widowhood mortality has revealed variation by socioeconomic status (SES), in that SES is not protective in widowhood, and by gender, such that men's mortality increases more than women's mortality after the death of spouse.

METHOD

Using data from the Health and Retirement Study, we estimated Cox proportional hazard models to estimate the association between widowhood and mortality.

RESULTS

Becoming widowed is associated with a 48% increase in risk of mortality. Approximately one third of the increase can be attributed to selection, in that those who become widows are socioeconomically disadvantaged. In contrast to previous studies, SES is protective for widows. Widowhood mortality risk increases for men if their wives' deaths were unexpected rather than expected; for women, the extent to which their husbands' death was expected matters less.

DISCUSSION

Widowhood's harmful association with mortality show how strongly social support and individual's health and mortality are related. These findings support the larger literature on the importance of social support for health and longevity.

Quality of life in dementia: a study on proxy bias

BACKGROUND

Measurement of health-related quality of life (HRQoL) in dementia is difficult. At some point people with dementia become unable to meaningfully assess their own HRQoL. At such a point in time researchers need to rely on other types of information such as observation or assessments from informal caregivers (proxies). However, caregiver assessments may be biased by several mechanisms. The current study explores whether caregivers project part of their own HRQoL in their assessments of patient HRQoL.

METHODS

The participants in the current study were 175 pairs, consisting of community-dwelling persons with dementia and their caregivers. The EQ-5D, the EQ-VAS and the QoL-AD were administered to collect HRQoL measurements from patients and caregivers at baseline, 6 months and 12 months. Two linear mixed models were used to investigate factors that bias proxy ratings, one with the EQ-VAS as dependent variable, and one with the EQ-5D utility as dependent variable. The independent variables were caregiver age, caregiver sex and caregiver QoL-AD items.

RESULTS

The linear mixed model with EQ-VAS as dependent variable indicated that 3 caregiver characteristics, namely caregiver age, money (caregiver's financial situation) and valuation of life as a whole were significant predictors of the patient-by-proxy VAS scores. The linear mixed model with utility value as the dependent variable showed that caregiver age and valuation of the ability to do things for fun were significant predictors of the patient-by-proxy EQ-5D utility values.

CONCLUSIONS

The current study was a first step in identifying factors that bias patient-by-proxy HRQoL assessments. It was discovered that caregivers project part of their own HRQoL onto patients when assessing patient HRQoL. This implies that patient-by-proxy HRQoL values should be interpreted with caution and not be used as a direct substitute for patient self-assessment, even when patients are no longer able meaningfully assess themselves.

The economic burden of cancers on Indian households

We assessed the burden of cancer on households’ out-of-pocket health spending, non-medical consumption, workforce participation, and debt and asset sales using data from a nationally representative health and morbidity survey in India for 2004 of nearly 74 thousand households. Propensity scores were used to match households containing a member diagnosed with cancer (i.e. cancer-affected households) to households with similar socioeconomic and demographic characteristics (controls). Our estimates are based on data from 1,645 households chosen through matching. Cancer-affected households experienced higher levels of outpatient visits and hospital admissions and increased out-of-pocket health expenditures per member, relative to controls. Cancer-affected households spent between Indian Rupees (INR) 66 and INR 85 more per member on healthcare over a 15-day reference period, than controls and additional expenditures (per member) incurred on inpatient care by cancer-affected households annually is equivalent to 36% to 44% of annual household expenditures of matched controls. Members without cancer in cancer-affected households used less health-care and spent less on healthcare. Overall, adult workforce participation rates were lower by between 2.4 and 3.2 percentage points compared to controls; whereas workforce participation rates among adult members without cancer were higher than in control households. Cancer-affected households also had significantly higher rates of borrowing and asset sales for financing outpatient care that were 3.3% to 4.0% higher compared to control households; and even higher for inpatient care.

Health Impacts of Caregiving for Older Adults With Functional Limitations

Objectives: To estimate the health impact, in terms of depression, self-rated health, and health services utilization, of providing care to older adults (75+) requiring human assistance in at least one activity of daily living (ADL) limitation. Method: Data from 1,077 caregivers and 318 noncaregivers, interviewed in the Singapore Survey on Informal Caregiving, was used to examine differences in depressive symptoms, self-rated health, and number of outpatient visits in the last 1 month between caregivers and noncaregivers. Multivariate models for the outcomes, adjusting for characteristics of the caregiver/noncaregiver and care-recipient/potential care recipient, were run. Results: Caregivers were more depressed, had poorer self-rated health, and had a higher rate of outpatient visits in the past month compared to noncaregivers. Discussion: The study indicates the need for support services to family caregivers of older adults with ADL limitations.

Sighs, smiles, and worried glances: how the body reveals women caregivers' lived experiences of care to older adults

This article reports on findings from microethnographic research that examined the lived reality of women caregivers through detailed observation of their everyday, embodied experiences. The research, which was rooted in the trend in social gerontology to emphasize subjective experience, focused on five women who were providing care to an older adult with a chronic illness or impairment. Four of the five women were caring for a spouse; one was caring for a parent. Observing the women's daily realities revealed tensions and contradictions between their subjective lived experiences and the pressures of the system in which they were functioning. The data revealed a caregiver habitus characterized by the performance of emotional labor. Performance was visible through dissonance between the caregivers' verbal and nonverbal expressions, and pointed to a high degree of emotion and body management. The women consistently put aside their own needs, in what can be considered a divestment in health capital. There was also evidence of merging between the caregiver and care receiver, made visible through tandem movements. The findings lead to implications for practice and for future aging research, including the benefits of observation for enhancing understanding of clients' experiences.

Transitions in caregiving and health dynamics of caregivers for people with AIDS: a prospective study of caregivers in Nairobi Slums, Kenya

OBJECTIVE

A cohort of older people living in a low-resource setting in Nairobi is followed to understand the transitions in caregiving status and trajectories in health over a 3-year period.

METHODS

Three categories of older people comprising 65 AIDS caregivers, 102 Other caregivers and 1,322 noncaregivers identified at baseline were assessed at end-line based on two self-reported health outcome measures, a functionality score and having a severe health problem.

RESULTS

A majority of caregivers were still providing care at the end of the study, and or had taken on new care recipients. Compared with noncaregivers, AIDS caregivers reported poor health, with men more likely to report poor health than women. New caregivers also reported poorer health compared with noncaregivers.

DISCUSSION

The results indicate improvement in health over time among male caregivers supporting the adaptation model. We recommend timely programs to support caregivers particularly at the onset of caregiving.

Psychological treatments for common mental health problems experienced by informal carers of adults with chronic physical health conditions (Protocol)

BACKGROUND

Improved life expectancy is resulting in increased outpatient treatment of people with chronic physical health conditions and reliance on the provision of informal care in the community. However, informal care is also associated with increased risk of experiencing common mental health difficulties such as depression and anxiety. Currently there is a lack of evidence-based treatments for such difficulties, resulting in poor health outcomes for both the informal carer and care recipient.

METHODS/DESIGN

Electronic databases will be systemically searched for randomised controlled trials examining the effectiveness of psychological interventions targeted at treating depression or anxiety experienced by informal carers of patients with chronic physical health conditions. Database searches will be supplemented by contact with experts, reference and citation checking and grey literature. Both published and unpublished research in English language will be reviewed with no limitations on year or source. Individual, group and patient-carer dyad focused interventions will be eligible. Primary outcomes of interest will be validated self-report or clinician administered measures of depression or anxiety. If data allows a meta-analysis will examine: (1) the overall effectiveness of psychological interventions in relation to outcomes of depression or anxiety; (2) intervention components associated with effectiveness.

DISCUSSION

This review will provide evidence on the effectiveness of psychological interventions for depression and anxiety experienced by informal carers of patients with chronic physical health conditions. In addition, it will examine intervention components associated with effectiveness. Results will inform the design and development of a psychological intervention for carers of people with chronic physical health conditions experiencing depression and anxiety.

Daily burdens of recipients and family caregivers after lung transplant

CONTEXT

Lung transplant recipients are prescribed a complex medical regimen that is thought to be burdensome and to interfere with daily activities of recipients and family caregivers. Yet empirical studies describing the activities that lung transplant recipients and their family caregivers perform on a typical day and the emotions associated with performing these activities are lacking.

OBJECTIVE

To identify the daily activities and burdens after lung transplant.

DESIGN

The Day Reconstruction Method and content analysis were used to reconstruct a typical day for lung transplant recipients and their family caregivers.

SETTING

The adult cardiothoracic transplant program of The University of Pittsburgh Medical Center.

PARTICIPANTS

Twenty-one dyads of lung transplant recipients and their family caregivers.

MAIN OUTCOME MEASURES

Variables of interest included lung transplant recipients' and family caregivers' daily activities and associated emotions, sociodemographics, clinical characteristics, and patient-reported outcomes of quality of life, symptoms of depression and anxiety, and functional performance.

RESULTS

Participants reported 286 daily activities and 138 associated positive and negative emotions. No activities or emotions were uniquely reported by lung transplant recipients or caregivers, providing evidence of the shared responsibility for caregiving and health maintenance. Most activities reported by caregivers and lung transplant recipients were health-related. Compared with lung transplant recipients, caregivers reported positive emotions more often, yet reported lower overall daily mood. This finding is consistent with results of previous studies indicating that specific caregiving tasks were typically rewarding for caregivers, but overall, care giving takes its toll.

CONCLUSION

Findings enhance our understanding of the burdens lung transplant recipients and caregivers face and point to the need for further support for dyads after lung transplant.

Advance care treatment plan (ACT-Plan) for African American family caregivers: a pilot study

Research is limited on end-of-life treatment decisions made by African American family caregivers. In a pilot study, we examined the feasibility of implementing an advance care treatment plan (ACT-Plan), a group-based education intervention, with African American dementia caregivers. Theoretically based, the ACT-Plan included strategies to enhance knowledge, self-efficacy, and behavioral skills to make end-of-life treatment plans in advance. Cardiopulmonary resuscitation, mechanical ventilation, and tube feeding were end-of-life treatments discussed in the ACT-Plan. In a four-week pre/posttest two-group design at urban adult day care centers, 68 caregivers were assigned to the ACT-Plan or attention-control health promotion conditions. Findings strongly suggest that the ACT-Plan intervention is feasible and appropriate for African American caregivers. Self-efficacy and knowledge about dementia, cardiopulmonary resuscitation, mechanical ventilation, and tube feeding increased for ACT-Plan participants but not for the attention-control. More ACT-Plan than attention-control participants developed advance care plans for demented relatives. Findings warrant a randomized efficacy trial.

Health behaviors among Baby Boomer informal caregivers

PURPOSE OF THE STUDY

This study examines health-risk behaviors among "Baby Boomer" caregivers and non-caregivers.

DESIGN AND METHODS

Data from the 2009 California Health Interview Survey of the state's non-institutionalized population provided individual-level, caregiving, and health behavior characteristics for 5,688 informal caregivers and 12,941 non-caregivers. Logistic regression models were estimated separately for four individual health-risk behaviors-smoking, sedentary behavior, and regular soda and fast-food consumption-as well as a global health-risk measure.

RESULTS

Controlling for psychological distress and personal characteristics and social resources such as age, gender, income and education, work and marital status, and neighborhood safety, caregivers had greater odds than non-caregivers of overall negative health behavior and of smoking and regular soda and fast-food consumption. We did not observe significant differences in odds of negative behavior related to stress for spousal caregivers and caregivers in the role for longer periods of time or those providing more hours of weekly care compared with other caregivers.

IMPLICATIONS

Our study found evidence that Baby Boomer caregivers engage in poor health behaviors that are associated with exposure to caregiving. Baby Boomer caregivers may be at risk for certain behavioral factors that are associated with disability and chronic illness.

The influence of the culture of care on informal caregivers' experiences

The environment of care can have a profound impact on caregiving experiences of families caring for loved ones with a life-limiting illness. Care is often delivered through disease-specific specialty clinics that are shaped by the illness trajectory. In this study, the following 3 distinct cultures of care were identified: interdisciplinary, provider dominant, and cooperative network. Each of these cultures was found to express unique values and beliefs through 5 key characteristics: acknowledgment of the certainty of death, role of the formal caregiver, perception of the patient system, focus of the patient visit across the trajectory, and continuum of care across the trajectory.

Does caring for a spouse with dementia promote cognitive decline? A hypothesis and proposed mechanisms

OBJECTIVE

To discuss why spouse caregivers (CGs) of people with dementia may be at higher risk for cognitive problems and decline than demographically similar people not caring for a spouse with dementia (noncaregivers; NCGs).

DESIGN

Literature review.

SETTING

Community.

PARTICIPANTS

Older adults caring for a family member (primarily spouses) with dementia.

MEASUREMENTS

Cognitive, psychosocial, physiological, and behavioral.

RESULTS

This article reports a review of the literature examining relationships between CG status and cognitive problems in the context of a theoretical model of chronic stress. The model suggests that spouse CGs may be at higher risk of cognitive impairment or dementia than NCG spouses in response to several mediators, including psychosocial (e.g., depression, loneliness, social isolation, sleep problems), behavioral (e.g., exercise, diet), and physiological (e.g., metabolic syndrome and inflammation) variables.

CONCLUSION

This research has important implications because it considers modifiable risk factors for dementia that, if unchecked, may compromise the lives of CGs and their ability to function. It is hoped that an understanding of such stress-mediator-cognitive processes will help clinicians, researchers, policy-makers, and stakeholders mitigate what may be characterized as an "ironic tragedy"-dementia in both members of the caregiving dyad-if left unchecked.

Protecting the health of employees caring for family members with special health care needs

Over half of American workers are holding a paid job while also providing unpaid assistance and support to a family member. Research shows that family members who provide care to children or adults with special health care needs are themselves at risk of physical and mental health problems. Yet, little research has explored how the work environment mediates the effects of caregiving on caregivers' mental and physical health. With a sample of 2455 currently employed U.S. adults from the Work, Family, Community Nexus (WFCN) survey, a random-digit dial, nationally representative survey of Americans aged 18-69, we examine whether paid leave and flexibility policies mediate the relationship between caregiving and health. In Ordinary Least Squares regression models, we find that paid leave to address family members' health was associated with better mental health status as measured by the 5-item Mental Health Inventory and paid sick leave with better physical health status as measured by self-rated overall health status. A supportive supervisor was also associated with improvements in mental and physical health. For both men and women, paid leave and a supervisor's support offset some or all of the negative effects of caregiving, but for women, the buffering effects of working conditions are slightly larger. Enhancing the unpaid leave guaranteed in the U.S. Family and Medical Leave Act so that it is paid and passing national paid sick days legislation will help ensure that employed caregivers can retain their jobs, receive needed income, and meet their own mental and physical health needs.

Self-efficacy buffers the relationship between dementia caregiving stress and circulating concentrations of the proinflammatory cytokine interleukin-6

OBJECTIVE

the proinflammatory cytokine interleukin (IL)-6 has been linked with health morbidity, particularly risk for cardiovascular disease (CVD). The purpose of this study was to investigate the potential protective role of coping self-efficacy on the relationship between caregiving stress and circulating concentrations of IL-6.

METHODS

a total of 62 elderly caregivers of patients with Alzheimer's disease (mean age: 74 years) were assessed for plasma concentrations of IL-6, caregiving-related overload, and coping self-efficacy. Multiple regression was used to examine the main effects of stress and self-efficacy, as well as the interaction between stress and self-efficacy, in predicting plasma IL-6 after controlling for age, gender, resting blood pressure, and obesity.

RESULTS

there was a significant interaction between stress and self-efficacy in predicting IL-6. Post-hoc examination indicated that when self-efficacy was low, stress was significantly related to IL-6 (β = 0.43). However, when self-efficacy was high, stress was not significantly related to IL-6 (β = -0.10).

CONCLUSION

caregiving stress in combination with low coping self-efficacy is significantly related to IL-6, a known risk marker for health morbidity, particularly CVD. However, stress was not associated with IL-6 with high self-efficacy. Although limited and preliminary, these results point to a potential protective effect of self-efficacy on caregiver health that can be tested in longitudinal studies.
