Health and frailty among older spousal caregivers: an observational cohort study in Belgium

The Caregiving Burden of Older People with Functional Deficits and Associated Factors on Malaysian Family Caregivers

Background

Providing care to older people can be an extremely complex task, given their increased functional deficits, which may lead to family caregivers experiencing burnout and a deteriorated health status. This study investigated the caregiving burden of older people with functional deficits on family caregivers and associated factors.

Methods

This cross-sectional study was conducted on family caregivers of older people with functional deficits living in FELDA schemes in Pahang, Malaysia. A self-administered questionnaire was used to collect data, which included the sociodemographical profile, health status and caregiving demands factors. The caregiving burden was assessed using the Malay version of the Zarit Burden Interview (ZBI). Multiple linear regression was used to assess the factors associated with burden.

Results

A total of 271 family caregivers completed the questionnaire. Their mean age was 45.8 (SD 0.9) years old. The mean score for caregiving burden was 18.5 (SD 13.6). Caregivers' gender (3.5 [95% CI: 0.2, 6.8]; P = 0.037), older people with chronic disease (9.6 [95% CI: 2.4, 16.9]; P = 0.010) and the functional independence of older people (-1.1 [95% CI: -1.6, -0.6]; P < 0.001) were predictors of family caregiving burden.

Conclusion

The caregiving burden among family caregivers was mild and influenced mainly by care recipients' health status. A proper assessment should be conducted and relevant health education provided to prepare family caregivers to care for their family members before discharge from the hospital.

The Vulnerability of Older Informal Caregivers with Care Needs: Significance of Multidimensional Frailty

OBJECTIVES

To improve our understanding of older informal caregivers' (ICs) health, this paper aimed to compare multidimensional frailty and sociodemographic and economic characteristics between (subgroups of) older ICs and non-caregivers.

METHODS

Using data originating from the Belgian Ageing studies (n = 6054), intergroup differences between older ICs and non-caregivers and between care-dependent and -independent older ICs/non-caregivers were conducted. In addition binary logistic regressions were carried out to determine which variables were related to caregiver status and need of assistance.

RESULTS

Among all respondents, 14.3% were ICs reporting care needs themselves. Informal and non-caregivers with care needs, relative to those without, more often only (partially) completed primary education, were significantly older, more likely to be female and widowed, found it more difficult to make ends meet, and reported higher levels of frailty in each domain. Moreover, environmental and psychological frailty were associated with an increase in the likelihood of reporting need of assistance among older non-caregivers and ICs, respectively.

CONCLUSIONS

This study revealed a particular vulnerable subpopulation of older ICs with care needs.

CLINICAL IMPLICATIONS

It is essential for clinicians to be observant for unrecognized frailty and care needs in older ICs and to develop targeted intervention and prevention strategies.

Hospitalization's association with depression in adults over 50 years old: does living arrangement matter? Findings from the Health and Retirement Study

OBJECTIVES

To examine how living arrangements are associated with depressive symptoms in late middle-life and older adults following hospitalization within the last two years.

DESIGN

We used the 2016 wave of the Health and Retirement Study (HRS), a nationally representative survey of adults over 50 years old living in the United States.

METHODS

The dependent variable was whether HRS participants screened positive for having depressive symptoms. The primary independent variable was self-reported hospitalization in the prior two years. We stratified bivariate analyses and multivariate logistic regressions by living arrangement to examine hospitalizations' association with depressive symptoms.

RESULTS

Depressive symptoms were less prevalent among participants who were married or partnered and living with a partner (14.0%) compared to those who were not married or partnered and were living with others (31.7%) and were not married or partnered and were living alone (27.8%). In multivariate analyses stratified by living arrangement, however, hospitalization was associated with depressive symptoms for those married or partnered and living with a partner (OR = 1.39, 95% CI: 1.14-1.69) but not for those who were not married and living with other(s) (OR = 0.88, 95% CI: 0.65-1.18) and not married or partnered and living alone (OR = 1.06, 95% CI: 0.82-1.36).

CONCLUSIONS

Late middle-life and older adults residing with spouses or cohabitating appear at risk for having depressive symptoms following a hospitalization. A better understanding of how relationships and living arrangements may affect depression risk in the context of an acute medical illness is needed to identify points of intervention.

Unmet needs and depression among spousal caregivers: the mediating role of marital satisfaction

OBJECTIVES

Previous research has identified that unmet needs are associated with adverse mental health outcomes in older adults. However, the unmet needs of older adults' spousal caregivers are unknown. The present study examined the association between unmet needs and depression among spousal caregivers, and whether marital satisfaction mediated this association.

METHODS

We included 1,856 participants who provided care to their spouses with difficulties in activities of daily living (ADL) and instrumental activities of daily living (IADL) from the 2018 China Health and Retirement Longitudinal Survey. Unmet needs of spousal caregivers were assessed as the total number of ADL/IADL tasks with which respondents had unmet needs. Path models were conducted to evaluate the associations between unmet needs, marital satisfaction, and depression. Subgroup analyses by sex were conducted to examine the sex differences regarding the associations.

RESULTS

Spousal caregivers with more unmet ADL/IADL needs reported higher levels of depression (p < 0.001). Additionally, for wife caregivers, unmet ADL/IADL needs were associated with lower marital satisfaction, and lower marital satisfaction was associated with higher degrees of depression, indicating that marital satisfaction partially mediated the association between unmet needs and depression (p < 0.01). However, marital satisfaction did not mediate the association between unmet needs and depression among husband caregivers.

CONCLUSIONS

The mediating effect of marital satisfaction on the association between unmet needs and depression only existed in wife caregivers. Social services should be provided to meet the needs of caregivers with ADL/IADL difficulties, and interventions should be implemented to promote the marital satisfaction of wife caregivers.

Variability in perceived burden and health trajectories among older caregivers: a population-based study in Sweden

BACKGROUND

The negative effects of informal caregiving are determined by the characteristics of the caregiver-care receiver dyad and the context of care. In this study, we aimed to identify which subgroups of older informal caregivers (1) experience the greatest subjective burden and (2) incur a faster decline in objective health status.

METHODS

From a total of 3363 older participants in the Swedish National study on Aging and Care in Kungsholmen (SNAC-K), we identified 629 informal caregivers (19.2%, mean age 69.9 years). Limitations to life and perceived burden were self-reported, and objective health status was quantified using the comprehensive clinical and functional Health Assessment Tool (HAT) score (range: 0-10). Ordered logistic regressions and linear mixed models were used to estimate the associations between caregiving-related exposures and subjective outcomes (cross-sectionally) and objective health trajectories (over 12 years), respectively.

RESULTS

Having a dual role (providing and receiving care simultaneously), caring for a spouse, living in the same household as the care receiver and spending more hours on caregiving were associated with more limitations and burden. In addition, having a dual role (β=-0.12, 95% CI -0.23 to -0.02) and caring for a spouse (β=-0.08, 95% CI -0.14 to -0.02) were associated with a faster HAT score decline. Being female and having a poor social network were associated with an exacerbation of the health decline.

CONCLUSIONS

Both the heterogeneity among caregivers and the related contextual factors should be accounted for by policymakers as well as in future research investigating the health impact of informal caregiving.

Mapping instruments for assessing and stratifying frailty among community-dwelling older people: a scoping review

OBJECTIVE

To map in the current literature instruments for the assessment and stratification of frailty in community-dwelling older people, as well as to analyse them from the perspective of the Brazilian context.

DESIGN

Scoping review.

STUDY SELECTION

The selection of studies took place between March and April 2020. Includes electronic databases: Medline, Latin American and Caribbean Literature in Health Sciences, Scopus, Web of Science and Cumulative Index of Nursing and Literature Health Alliance, in addition to searching grey literature.

DATA EXTRACTION

A data extraction spreadsheet was created to collect the main information from the studies involved, from the title to the type of assessment and stratification of frailty.

RESULTS

In summary, 17 frailty assessment and stratification instruments applicable to community-dwelling older people were identified. Among these, the frailty phenotype of Fried et al was the instrument most present in the studies (45.5%). The physical domain was present in all the instruments analysed, while the social, psychological and environmental domains were present in only 10 instruments.

CONCLUSIONS

This review serves as a guideline for primary healthcare professionals, showing 17 instruments applicable to the context of the community-dwelling older people, pointing out advantages and disadvantages that influence the decision of the instrument to be used. Furthermore, this scoping review was a guide for further studies carried out by the same authors, which aim to compare instruments.

Designing Ruby: Protocol for a 2-Arm, Brief, Digital Randomized Controlled Trial for Internalized Weight Bias

BACKGROUND

Weight bias internalization, also known as weight self-stigma, is a serious health concern for individuals with higher body weight. Weight bias internalization is associated with the greater avoidance of health care and health-promoting activities, disordered eating, social isolation, and weight gain. Elevated weight bias internalization has been associated with low self-compassion, yet few investigations have explored self-compassion as a potential mechanism for reducing internalized weight bias.

OBJECTIVE

Ruby is a 2-arm randomized controlled trial that was designed to test the efficacy of a 4-week digital self-compassion intervention to reduce internalized weight bias compared with a wait-list control.

METHODS

Adults with elevated internalized weight bias and a BMI of >30 kg/m² (N=80) were recruited. Ruby is a standalone digital trial that will be delivered entirely via a smartphone and will involve web-based data collection and text messages. The intervention content will include psychoeducation and daily mindfulness practices with a focus on self-compassion and body concerns. We will use intent-to-treat analyses to examine changes in weight bias internalization throughout time by treatment arm. The analyses will be conducted by using one-way analysis of covariance models and linear mixed models.

RESULTS

The protocol was designed in May 2020 and approved in December 2020. Data collection is currently underway.

CONCLUSIONS

Ruby will be the first digital standalone, self-compassion-based intervention designed to reduce internalized weight bias. Owing to its standalone digital delivery, Ruby may be a highly scalable treatment for internalized weight bias that can be delivered on its own or combined with other treatments. We expect Ruby to be accessible to many, as participants can access the digital intervention at times of the day that are the most convenient in their schedule and are not burdened by in-person time commitments, which can be a barrier for participants with competing demands on their time and resources. If efficacious, Ruby will be poised to expand a burgeoning body of literature related to psychological intervention in this area.

The Psychosocial Effects of Frailty on Women

Certain psychosocial elements, such as depression, anxiety, stress, lack of social support, and loneliness, should be considered as part of frailty. Women are more likely to be frail toward the end of life, because they live longer and are less likely to develop diseases with abrupt ends. Women are also more prone to develop psychosocial elements associated with frailty because of their lifetime stressors, poverty, and loneliness at the end of life. Clinicians should recognize this phenomenon and create early interventions to ensure women are able to live according to their preferences during the last part of their lives.

Persons with dementia and informal caregivers prioritizing care: A mixed-methods study

INTRODUCTION

More persons with dementia are residing in the community as many countries shift from residential care to home and community care. Although there are many forms of care and support available to avoid crisis situations and prolong community living, it remains unclear how these are valued by community-dwelling persons with dementia and their informal caregivers. Understanding perspectives of persons with dementia and informal caregivers on care characteristics is a vital step in valuing care services. This study aims to prioritize care characteristics for community-dwelling persons with dementia and informal caregivers with the use of an innovative mixed-methods approach.

METHODS

Six mixed focus groups were conducted in The Netherlands with persons with dementia (n = 23) and informal caregivers (n = 20), including a quantitative ranking exercise that prioritized seven care and support characteristics from "most important" to "least important," followed by a group discussion about the prioritization. Audio recordings were transcribed and analyzed using thematic analysis.

RESULTS

The ranking exercise and discussion showed that persons with dementia favored in-home care, help with daily activities, and social activities, whereas informal caregivers favored social activities, information about dementia, navigating the health care system, and emotional support.

DISCUSSION

Persons with dementia prioritized day-to-day activities, whereas informal caregivers preferred assistance with organizing care and coping with caregiving. This study created a method to capture the care preferences of persons with dementia and informal caregivers.

Profile and needs of primary informal caregivers of older patients in Belgian geriatric day hospitals: a multicentric cross-sectional study

Background

With the improvement of life expectancy, the world faces increasing demands for care of older persons. In this manuscript, we define the characteristics of primary informal caregivers (PIC) of patients aged 75 years and older admitted to geriatric day hospitals (GDH) in Belgium. A PIC is defined as the person who most often provides care and assistance to persons who need to be cared for. We describe PIC socio-demographic characteristics, satisfaction, burden and wishes about caring; the type of assistance provided and received, their self-rated health, socio-demographic and medical characteristics of proxies, in particular the presence of behavioural disorders.

Methods

We conducted a cross-sectional study in 25 GDH.

Participants

Four hundred seventy-five PIC of patients ≥75 years and their proxies. PIC completed a questionnaire at the GDH assessing burden by Zarit Burden Index-12 (ZBI-12), self-rated health, social restriction due to caregiving and financial participation. We compared the characteristics of PIC with high and low burden, and the characteristics of spouses and adult children PIC. We also analyzed factors associated with a high burden in a multivariable logistic regression model.

Results

PIC were mainly women (72%), adult children (53.8%) and spouses (30.6%). The mean age was 64 ± 14 years for PIC and 84 ± 5 years for care recipients. PIC helped for most of Activities in Daily Living (ADL) and Instrumental ADL (iADL). The median ZBI-12 score was 10 [IQR 5–18]. In multivariable regression analysis, a high burden was positively associated in the total group with living with the relative (p = 0.045), the difficulty to take leisure time or vacation (p <  0.001), behavioral and mood disorders (p <  0.001;p = 0.005), and was negatively associated with bathing the relative (p = 0.017) and a better subjective health status estimation (p <  0.001).

Conclusion

Primary informal caregivers, who were predominantly women, were involved in care for ADL and iADL. A high burden was associated with living with the relative, the difficulty to take leisure time or vacation and the relative’s behavioral and mood disorders. Bathing the relative and a subjective health status estimated as good as or better than people the same age, were protective factors against a high burden.

Spousal Care and Pain Among the Population Aged 65 Years and Older: A European Analysis

Background: Spousal care is the most important source of informal care in old age. Nevertheless, despite the growing importance of this issue, the association between providing spousal care inside the household and pain remains unexplored in Europe.

Objective and Methods: This study aims to estimate the prevalence of pain reported by spouse caregivers aged 65 plus that provide care inside the household and to investigate the association between providing spousal care and pain. Data from 17 European countries that participated in wave 6 of the Survey of Health, Aging and Retirement in Europe (SHARE) is used. The analyses are based on 26,301 respondents aged 65 years and older who provide informal care inside the household to their spouse/partner exclusively (N = 1,895) or do not provide any informal care (inside or outside the household) (24,406). Descriptive statistics and multilevel logistic regressions (individual-level as level 1, and country as level 2) were performed.

Results: Overall, spouse caregivers report pain more often (63.4%) than their non-caregiver‘s counterparts (50.3%). Important differences in the prevalence of pain among spouse caregivers were found between countries, with Portugal (80.3%), Spain (74.6%), France (73%), Italy (72.4%), and Slovenia (72.1) showing the highest prevalence of pain, and Denmark (36%), Switzerland (41.5) and Sweden (42.3%), the lowest. Results from multilevel logistic regressions show that European individuals aged 65+ who provide spousal care have an increased likelihood of reporting pain (OR 1.30; CI = 1.13–1.48).

Conclusion: Our results suggest that in Europe, spouse caregivers aged 65+ are at greater risk of experiencing pain. Therefore, European policymakers should consider spouse caregivers as a health priority group, and take measures to ensure they receive comprehensive health and socio-economic support.

Bridging the Gap: A Mixed Methods Study Investigating Caregiver Integration for People with Geriatric Syndrome

Introduction

Transitions of care between acute hospital and community settings are points of vulnerability for people with geriatric syndrome. Routinely including informal caregivers into the transition processes may mitigate risk. Guidance for operational aspects of caregiver inclusion is currently lacking in healthcare policy and fails to address the barriers faced by caregivers and healthcare professionals.

Methods

A questionnaire and a semi-structured interview were piloted with acute care physiotherapists who facilitate patient discharge into community settings. The questionnaire was analysed using summary statistics and interviews were thematically analysed by researchers, using NVivo 12 software.

Results

Questionnaire responses indicated mixed satisfaction with current caregiver integration by the multidisciplinary team. Four themes were shaped in the interviews: inconsistent caregiver engagement, individuals working in a system, an outdated model of care, and invisible care gaps.

Discussion

Feedback loops constructed from participant questionnaires and interview responses informed the identification of barriers and solutions. These are system wide and address automated integration, cultural shift, reimbursement models, and flexible structures to enhance informal caregiver participation. Future research is urgently required to translate, implement, and evaluate enhanced caregiver integration to ensure sustainable, person-centred healthcare delivery.

Nutritional Assessment in Older Adults : MNA® 25 years of a Screening Tool and a Reference Standard for Care and Research; What Next?

A tool to assess nutritional status in older persons was really needed. It took 5 years to design the MNA® (Mini Nutrition Assessment) tool, complete the first validations studies both in Europe and in the U.S. and to publish it. After the full MNA®, the MNA® short form and the self-MNA® have been validated. As well as Chinese and other national MNA® forms. Now more than 2000 clinical research have used the MNA® all over the world from community care to hospital. At least 22 Expert groups included the MNA® in new clinical practice guidelines, national or international registries. The MNA® is presently included in almost all geriatric and nutrition textbook and part of the teaching program for medicine and other health care professional worldwide. The urgent need is to target the frail older adults more likely to have weight loss and poor appetite and to prevent frailty and weight loss in the robust. We present in this paper the review of 25 years of clinical research and practice using the MNA® worldwide.

METAMORFOSIS IN THE LIVES OF ELDERLY PEOPLE CARING FOR DEPENDENT ELDERLY IN BRAZIL

ABSTRACT Objective: to understand the phenomenon concerning the change in life and routine of elderly family caregivers who care for dependent elderly family members in Brazil. Method: qualitative, exploratory and descriptive study, developed with 33 elderly family caregivers, from June to September 2019, in the cities of Belo Horizonte, Rio de Janeiro, Porto Alegre, Araranguá, Manaus, Fortaleza and Teresina. Semi-structured interviews were conducted based on the theme of care, facilitating circumstances and difficulties. The analysis of the information was guided by the theoretical-methodological framework of hermeneutics-dialectics. Results: a comprehensive model of the experience of being an elderly caregiver of a dependent elderly family member. This process was part of two categories: "Assuming care" and "Unmet needs". The facilitating circumstances to assume care were positive emotions and bonds with the older person, acceptance of the disease, stable clinical status and support from health professionals, formal caregivers, domestic employees and family support. The difficulties were when the behavior of the dependent elderly becomes aggressive, experiencing loneliness, poor health, social isolation, financial restrictions and absence of social and health support. Conclusion: elderly caregivers are important agents in the exercise of care for the dependent elderly. When they have support, they can perform the care activities and have time to take care of themselves. However, for the most part, these people give up their lives, withdraw from the labor market, isolate themselves and suffer from the lack of material resources and support from health services.

Complex mental health needs in older people living with frailty

Frailty describes a state of health whereby people develop multiple or cumulative deficits in physiological systems over the life course, leading to vulnerability and being less able to respond to acute and/or physiological stressors, which at times may be relatively minor. Mental health should be an important consideration in the assessment and management of frailty in older people. This article provides an overview and clinical perspective on the evidence relating to frailty and mental health assessment and management.

Natural Regression of Frailty Among Community-Dwelling Older Adults: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Frailty is a dynamic process with potential transitions over time. However, there is limited understanding of the patterns of frailty improvement. We conducted a systematic review and meta-analysis to estimate the natural rate of frailty regression among community-dwelling older adults aged at least 60 years.

RESEARCH DESIGN AND METHODS

Systematic searches for studies reporting frailty improvement were performed in 5 databases (Medline, Embase, CINAHL plus, Web of Science, and PsycINFO) from inception until January 2019.

RESULTS

Twenty-five studies from 26 countries were included. Among a baseline population of more than 50,000 individuals, the pooled prevalence of pre-frailty and frailty was 50.5% (95% confidence interval [CI] 47.8-53.3) and 12.8% (95% CI 9.1-17.0), respectively. During a median follow-up of 3.0 (range 1-10.0) years, 23.3% of surviving pre-frail individuals regressed to a robust state and 35.2% of surviving frail individuals reversed to a pre-frail or robust state. The pooled remission rates among people with pre-frailty and frailty were 80.4 (95% CI 61.7-104.6) and 135.3 (95% CI 98.1-186.5) per 1,000 person-years, respectively. Frailty and pre-frailty improvement rates varied by sex, diagnostic criteria, study region, and follow-up duration. The remission rates were significantly reduced when accounting for progressions to death. The heterogeneity of included studies was high which reflected considerable differences in methodological approach.

DISCUSSION AND IMPLICATIONS

Although frailty is highly prevalent in older people, natural remission is possible and common. Improved understanding of the factors that confer increased likelihood of frailty regression may support the design of interventions to reduce the burden of frailty.

Do European co-residential caregivers aged 50+ have an increased risk of frailty?

One important health challenge associated with ageing is frailty, which has been acknowledged as a new public health priority. However, only a few studies have explored the relationship between providing care at older ages and frailty. The main objective of this study is to assess whether there is an association between providing co-residential care and frailty, according to gender and from a European cross-sectional perspective, among the population aged 50+. Data from 17 European countries that participated in wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE) is used (N = 52,073). Multinomial logistic regressions were used to estimate caregivers' chances of frailty. The results show that the prevalence of pre-frailty and frailty differs according to the caregiver's status, gender and the European region. The highest prevalence of pre-frailty was found in the group of female caregivers from Northern countries (57.3%), and the highest prevalence of frailty was found in the group of female caregivers from Southern countries (29.3%). Providing co-residential care is positively associated with the risk of being pre-frail in women, in all European regions (Northern: OR 1.724, 95% CI 1.190-2.496; Central: OR 1.213, 95% CI 1.010-1.456; Eastern: OR 1.227, 95% CI 1.031-1.460; Southern: OR 1.343, 95% CI 1.103-1.634), and with being frail for both genders in the Southern region (female: OR 1.527, 95% CI 1.060-2.200; male: OR 1.644, 95% CI 1.250-2.164). The results of this study suggest that female co-residential caregivers are a greater risk of being pre-frail in all European regions except Southern Europe, where male and female co-residential caregivers are a greater risk of being frail, compared with non-caregivers. European policy makers should create political measures to prevent and reverse frailty among European co-residential caregivers.

Spousal Concordance of Physical Frailty in Older Korean Couples

Marital status is an important risk factor for physical frailty. However, there are limited data on spousal concordance of physical frailty among married couples. Here, we evaluate the spousal concordance of frailty as defined by the Fried frailty phenotype and specific phenotype components that contribute to this association. Data on 315 married couples (630 individuals) aged between 70 and 84 years were obtained from the Korean Frailty and Aging Cohort Study (KFACS). Multivariate logistic regressions were used for the analysis. After adjusting for covariates (age, body mass index, education, house ownership, comorbidity, cognition, depressive symptoms, cohabitation with adult children for both partners), a husband’s frailty was positively associated with his wife’s frailty (odds ratio (OR) 3.34, 95% confidence interval (CI) 1.04–10.73, p < 0.05), and a wife’s frailty was significantly associated with her husband’s frailty (OR 4.62, 95% CI 1.31–16.33, p < 0.05), indicating a greater effect of the frailty status of the spouse among women than among men. Among the five components of the Fried frailty phenotype, weight loss, slowness, and exhaustion were the main contributing factors to the spousal association for frailty. In conclusion, having a frail spouse is a strong and independent risk factor for frailty among community-living older adults.

Experiences of oldest-old caregivers whose partner is approaching end-of-life: A mixed-method systematic review and narrative synthesis

Population ageing has rapidly increased the number of people requiring end-of-life care across the globe. Governments have responded by promoting end-of-life in the community. Partly as a consequence, older spouses are frequently providing for their partner's end-of-life care at home, despite potentially facing their own health issues. While there is an emerging literature on young-old caregivers, less is known about spouse carers over 75 who are likely to face specific challenges associated with their advanced age and relationship status. The aim of this review, therefore, is to identify and synthesise the literature concerning the experiences of caregiver's aged 75 and over whose partner is approaching end-of-life. We conducted a mixed-method systematic review and narrative synthesis of the empirical literature published between 1985 and May 2019, identified from six databases: Medline, PsychINFO, Cumulative Index to Nursing and Allied Health Literature, Embase, Sociological Abstracts and Social Service Abstracts. Hand searching and reference checking were also conducted. Gough's Weight of Evidence and Morgan's Feminist Quality Appraisal tool used to determine the quality of papers. From the initial 7819 titles, 10 qualitative studies and 9 quantitative studies were included. We identified three themes: 1) "Embodied impact of care" whereby caring was found to negatively impact carers physical and psychological health, with adverse effects continuing into bereavement; 2) "Caregiving spouse's conceptualisation of their role" in which caregiver's navigated their self and marriage identities in relation to their partner's condition and expectations about gender and place; 3) "Learning to care" which involved learning new skills and ways of coping to remain able to provide care. We identified a recent up-surge in published papers about very old spousal caregivers, which now comprise a small, medium-quality evidence base. This review outlines a range of potential lines of inquiry for future research including further clarification of the impact of caregiving on the likelihood of mortality, the incidence of men and women providing end-of-life care amongst this age group, and the role of anticipatory grief in shaping their perceptions of their relationship and their own longevity.

Pre-frailty, frailty and associated factors in older caregivers of older adults

INTRODUCTION

Providing care to an older adult is an activity that requires considerable physical effort and can cause stress and psychological strain, which accentuate factors that trigger the cycle of frailty, especially when the caregiver is also an older adult. However, few studies have analyzed the frailty process in older caregivers.

OBJECTIVES

To investigate the prevalence of pre-frailty, frailty and associated factors in older caregivers of older adults.

METHODS

A cross-sectional study was conducted including 328 community-dwelling older caregivers. Frailty was identified using frailty phenotype. Socio-demographic, behavioral and clinical aspects, characteristics related to care and functioning were covariables in the multinomial logistic regression.

RESULTS

The prevalence of pre-frailty and frailty were 58.8% and 21.1%, respectively. An increased age, female sex, not having a conjugal life, depressive symptoms and pain were commonly associated with pre-frailty and frailty. Sedentary lifestyle was exclusively associated with pre-frailty, whereas living in an urban area, low income and the cognitive decline were associated with frailty. A better performance on instrumental activities of daily living reduced the chance of frailty.

CONCLUSION

Many factors associated with the frailty syndrome may be related to the act of providing care, which emphasizes the importance of the development of coping strategies for this population.

Global Incidence of Frailty and Prefrailty Among Community-Dwelling Older Adults: A Systematic Review and Meta-analysis

IMPORTANCE

Frailty is a common geriatric syndrome of significant public health importance, yet there is limited understanding of the risk of frailty development at a population level.

OBJECTIVE

To estimate the global incidence of frailty and prefrailty among community-dwelling adults 60 years or older.

DATA SOURCES

MEDLINE, Embase, PsycINFO, Web of Science, CINAHL Plus, and AMED (Allied and Complementary Medicine Database) were searched from inception to January 2019 without language restrictions using combinations of the keywords frailty, older adults, and incidence. The reference lists of eligible studies were hand searched.

STUDY SELECTION

In the systematic review, 2 authors undertook the search, article screening, and study selection. Cohort studies that reported or had sufficient data to compute incidence of frailty or prefrailty among community-dwelling adults 60 years or older at baseline were eligible.

DATA EXTRACTION AND SYNTHESIS

The methodological quality of included studies was assessed using The Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence and Incidence Studies. Meta-analysis was conducted using a random-effects (DerSimonian and Laird) model.

MAIN OUTCOMES AND MEASURES

Incidence of frailty (defined as new cases of frailty among robust or prefrail individuals) and incidence of prefrailty (defined as new cases of prefrailty among robust individuals), both over a specified duration.

RESULTS

Of 15 176 retrieved references, 46 observational studies involving 120 805 nonfrail (robust or prefrail) participants from 28 countries were included in this systematic review. Among the nonfrail individuals who survived a median follow-up of 3.0 (range, 1.0-11.7) years, 13.6% (13 678 of 100 313) became frail, with the pooled incidence rate being 43.4 (95% CI, 37.3-50.4; I2 = 98.5%) cases per 1000 person-years. The incidence of frailty was significantly higher in prefrail individuals than robust individuals (pooled incidence rates, 62.7 [95% CI, 49.2-79.8; I2 = 97.8%] vs 12.0 [95% CI, 8.2-17.5; I2 = 94.9%] cases per 1000 person-years, respectively; P for difference < .001). Among robust individuals in 21 studies who survived a median follow-up of 2.5 (range, 1.0-10.0) years, 30.9% (9974 of 32 268) became prefrail, with the pooled incidence rate being 150.6 (95% CI, 123.3-184.1; I2 = 98.9%) cases per 1000 person-years. The frailty and prefrailty incidence rates were significantly higher in women than men (frailty: 44.8 [95% CI, 36.7-61.3; I2 = 97.9%] vs 24.3 [95% CI, 19.6-30.1; I2 = 8.94%] cases per 1000 person-years; prefrailty: 173.2 [95% CI, 87.9-341.2; I2 = 99.1%] vs 129.0 [95% CI, 73.8-225.0; I2 = 98.5%] cases per 1000 person-years). The incidence rates varied by diagnostic criteria and country income level. The frailty and prefrailty incidence rates were significantly reduced when accounting for the risk of death.

CONCLUSIONS AND RELEVANCE

Results of this study suggest that community-dwelling older adults are prone to developing frailty. Increased awareness of the factors that confer high risk of frailty in this population subgroup is vital to inform the design of interventions to prevent frailty and to minimize its consequences.

Impact of Nutritional Status on Caregiver Burden of Elderly Outpatients. A Cross-Sectional Study

The assistance to older community-dwellers provided by family caregivers is crucial for the maintenance of an acceptable quality of life, especially when dementia is present. The caregiver burden may be extremely high, but few data are available on what patient domains mainly affect the caregiver. The aim of this cross-sectional study, performed in older outpatients, was to examine the impact of cognitive, physical and nutritional status of elderly community-dwellers on the caregiver burden, as evaluated by the Caregiver Burden Inventory (CBI). A group of 406 elderly outpatients (161 M, 245 F, mean age of 83.20 ± 6.40) was enrolled. A significant correlation was observed between Mini Nutritional Assessment Instrument-Short Form (MNA-SF) and CBI (r = −0.34; p < 0.001), suggesting that a poor nutritional status is significantly associated with the caregiver burden. There was also a significant correlation between CBI and Short Physical Performance Battery score (r = −0.29; p < 0.001), hand grip strength (r = −0.25; p < 0.001), Mini-Mental State Examination score (r = −0.39; p < 0.001), Geriatric Depression Scale (r = 0.23; p < 0.001), Body Mass Index (BMI) (r = 0.01; p = 0.03), Activities of Daily Living and Instrumental Activities of Daily Living (ADL/IADL) (r = −0.61 and −0.62, respectively; p < 0.001), and with the 4-m walking speed (r = −0.42; p < 0.001). In the multivariate analysis, only the relationships of the CBI (in particular the physical subcomponent) with ADL, IADL and MNA-SF remained statistically significant (β ± SE −0.89 ± 0.20, p < 0.001; −0.58 ± 0.15, p < 0.001 and −0.25 ± 0.11, p = 0.02, respectively). The relationship between CBI and BMI remained statistically significant only for the physical subcomponent (β ± SE 0.14 ± 0.05; p = 0.006). Thus, in this study, we confirmed that the impairment in the activities of daily living is associated with a significant impact on the caregiver burden, and we found also that a poor nutritional status of the older outpatient is independently more associated with the caregiver burden than cognitive and physical disability. The combined evaluation of both patients and caregivers can improve the knowledge and assistance to the elderly subjects.
