Effects of a Home-Based Exercise Program on Health-Related Quality of Life and Physical Fitness in Dementia Caregivers: A Randomized Controlled Trial

Regular exercise can be an effective health-promotion strategy to improve the physical and mental health of informal caregivers. A randomized controlled trial study was designed to evaluate the effects of a 9-month home-based exercise intervention on health-related quality of life (HRQoL) and physical fitness in female family caregivers of persons with dementia. Fifty-four female caregivers were randomly assigned to two groups for the 9-month study period. Participants of the intervention group (n = 25) performed two 60-min exercise sessions per week at home, under the direct supervision of a personal trainer. Participants in the control group (n = 23) continued their habitual leisure-time activities. HRQoL was assessed using the SF-36 questionnaire, and physical fitness was measured using a battery of appropriate fitness tests. After 9 months, significant improvements were observed in general health, social function, vitality, hand and leg strength, trunk flexor and extensor endurance, and aerobic endurance in the intervention group. The present intervention was highly adherent and safe for the participants, with no dropout related to the intervention. As a home-based exercise program conducted by a personal trainer face to face, it can be considered as a feasible and appropriate method to improve the most deficient HRQoL dimensions and contribute to preserving the functional capacity of female family caregivers of persons with dementia.

Unmet needs and health-related quality of life of dementia family caregivers transitioning from home to long-term care: A scoping review

This scoping review is to identify experiences, unmet needs, and health-related quality of life (HRQoL) of family caregivers transitioning their care recipients with dementia into long-term care (LTC). The methodological framework of Arksey and O'Malley guided the review. Themes from nineteen selected studies were organized around three categories. First, caregiver experiences during LTC placement featured challenges around placement decision-making and distress and changes in relationships and responsibilities. Second, unmet needs of caregivers were desired emotional support and information about transitions. Finally, caregivers' HRQoL varies around transition. Family caregivers experience unique challenges and can have unmet needs during the LTC placement of their care recipients with dementia. Findings suggest the need for interventions that teach skills, care planning, assistance with conflict resolution, communication training, and guidance finding services and resources.

Síndrome de sobrecarga y estrategias de afrontamiento en cuidadores principales de pacientes oncológicos pediátricos

Objetivo: Los cuidadores oncológicos pediátricos se encontrarán con circunstancias que llegarán a desafiar sus recursos personales para afrontar las diversas demandas propias del cuidado. Por lo tanto, el objetivo del estudio fue determinar la relación entre el síndrome de sobrecarga y las estrategias de afrontamiento en cuidadores de pacientes oncológicos pediátricos. Método: Participaron 93 cuidadores principales de pacientes oncológicos pediátricos (69,9% mujeres, 30,1% varones, edad promedio =37,20 años, DE=11,32), seleccionados de forma no probabilística. Se aplicó la Escala de Sobrecarga del Cuidador y el Cuestionario COPE-28. Se utilizaron estadísticos correlacionales y comparativos para el análisis de datos. Resultados: Los resultados indican la presencia de correlaciones significativas e inversas que varían entre r = -,25 y r = -,56. Sin embargo, no se evidenció una asociación significativa entre las dimensiones de la sobrecarga del cuidador y el uso de sustancias. Por otro lado, aquellos cuidadores que utilizan estrategias poco adaptativas, son más propensos a generar sobrecarga frente a su rol, influyendo en su vida personal, familiar y social. Conclusión: Existe una relación significativa entre el síndrome de sobrecarga y las estrategias de afrontamiento. Además, se identifican diferencias significativas en la sobrecarga según el lugar de procedencia y las horas dedicadas al cuidado.

Costs and resource use of community-dwelling patients with Alzheimer's disease in Japan: 18-month results from the GERAS-J study

OBJECTIVE

To determine the longitudinal societal costs and burden of community-dwelling patients with Alzheimer's disease (AD) and their caregivers in Japan.

METHODS

GERAS-J was an 18-month, prospective, longitudinal, observational study. Using the Mini-Mental State Examination (MMSE), patients routinely visiting memory clinics were stratified into groups based on AD severity at baseline (mild, moderate, and moderately severe/severe [MS/S]). Healthcare resource utilization and caregiver burden were assessed using the Resource Utilization in Dementia and Zarit "Caregiver" Burden Interview questionnaires, respectively. Total monthly societal costs were estimated using Japan-specific unit costs of services and products (patient direct healthcare use, patient social care use, and informal caregiving time).

RESULTS

Overall, 553 patients (156 mild; 209 moderate; 188 MS/S) were enrolled. MMSE scores declined (1.73, 1.38, and 0.95 points for the mild, moderate, and MS/S AD groups, respectively) and caregiver burden and resource utilization increased over 18 months in each of the AD severity groups. Cumulative total societal costs per patient over 18 months were 3.1, 3.8, and 5.3 million Japanese yen (29,006, 35,662, and 49,725 USD) for mild, moderate, and MS/S AD, respectively. Both patient social care costs and caregiver informal care costs increased with baseline disease severity, with >50% of total costs due to caregiver informal care in each disease severity subgroup.

CONCLUSIONS

Total treatment costs increased with AD severity over 18 months due to increases in both patient social care costs and caregiver informal care costs. Our data suggest current social care services in Japan are insufficient to alleviate the negative impact of AD on caregiver burden.

Development of multi-component counseling program for enhancing resilience among Thai caregivers of older persons with dementia

Purpose

The purpose of this study was to develop a multi-component counseling program and examine the short-term effects of an 8-session program.

Design/methodology/approach

This present study was a research and development of a multi-component counseling program for enhancing resilience. The concept of resilience was reviewed based on a synthesis of existing research, together with an exploration of qualitative data derived from an interview with ten caregivers of older persons with dementia. Six domains of resilience were identified: physical, relationships, emotional, moral, cognitive and spiritual; which were then used to develop the eight-week program. The program was examined by a panel of three experts for content validity, which yielded an index of 0.87. The program was then tried out with 60 caregivers recruited and assigned 30 caregivers in the intervention and control group. The Caregiver’s Resilience Scale (CRS) was used by trained nurses to evaluate the program and data were analyzed using repeated measures ANOVA.

Findings

The results indicated that the resilience scores of the participants in the intervention group were statistically significantly higher than those of the control group at one month after program participation and at the follow-up three months later (p < 0.05).

Originality/value

It could be concluded that the program yielded support for the evidence-based practice of non-pharmacological intervention. The program would be suitable as a clinical practice guideline to provide help to caregivers of older persons with dementia at the outpatient setting.

Effects of a home-based exercise program on mental health for caregivers of relatives with dementia: a randomized controlled trial

OBJECTIVE

This study was aimed to evaluate the effectiveness of a home-based physical exercise program on participants' mental health: psychological symptoms, depression, and burden of female informal caregivers.

DESIGN AND PARTICIPANTS

In a randomized controlled trial, a sample of 48 female informal primary caregivers completed the entire study, 25 were randomly allocated to the intervention group (IG), and 23 participants to the control group (CG).

INTERVENTION

Participants in the IG performed two 60-minute-long physical exercise sessions per week (36 weeks) that were supervised by a personal trainer at caregivers' home during 9 months. The CG continued their habitual leisure-time activities.

MEASUREMENTS

Subjective burden was assessed by the Zarit Burden Interview. The risk of depression was measured by the Geriatric Depression Scale Short Form 15-item version, and psychological symptoms were evaluated by the Symptom Check List-90-Revised (SCL-90-R). All participants were evaluated at baseline and at the end of the intervention.

RESULTS

A promising positive impact of the intervention on caregivers' subjective burden and risk of depression was found in the IG. In addition, no significant between-group differences were found in any of nine subscales scores of the SCL-90-R. Finally, care recipients' level of functional independence and area of residence were found to be predictors of the promising positive impact on caregivers' subjective burden and risk of depression.

CONCLUSIONS

The present home-based physical exercise intervention that was individually implemented has shown promising results to reduce subjective burden and risk of depression in female caregivers of relatives with dementia. However, future research efforts should elucidate both the particular dose of physical exercise and the particular duration of the intervention that are required to obtain the expected significant positive impact. Finally, future inclusion of psychological approaches, besides physical exercise, might help reduce female caregivers' psychological symptoms.

Contributors and Moderators of Quality of Life in Caregivers of Alzheimer´s Disease Patients

Aim and objective: This study aimed to identify the variables that contributed to Quality of Life (QoL) of Alzheimer's Disease (AD) caregivers, taking into consideration the caregiving context, stressors, role strains, and resources.Methods: The sample included 102 caregivers of AD patients who answered the following instruments: Depression, Anxiety and Stress Scale-21; Satisfaction with Social Support Scale; Revised Memory and Behavioral Problems Checklist; Family Communication and Satisfaction Scales; Spiritual and Religious Attitudes in Dealing with Illness; and Quality of Life in Alzheimer's Disease - Caregiver Version.Results: Caregivers who were employed, chose the caregiving role, and received help in caring showed better QoL. Also, being younger, less caregiving daily hours, caring for patients with less memory and behavior problems, lower distress, and family satisfaction predicted better QoL. Finally, spirituality was a moderator between family communication and QoL but not between family satisfaction and QoL.Conclusion: Caregiving-context variables (age, professional status, choosing to care, receiving help in the caregiving role and duration of daily care); role strains (family dissatisfaction); stressors (caregivers' distress and patients' memory and behavioral problems); and resources (spirituality) had an impact on caregivers' QoL emphasizing the adequacy of the Stress Process Model. Intervention should also focus on spirituality given its moderating role.

A dyadic approach for a remote physical activity intervention in adults with Alzheimer's disease and their caregivers: Rationale and design for an 18-month randomized trial

Adults with Alzheimer's disease and related dementia (ADRD) and their caregivers represent a sizeable and underserved segment of the population with low levels of moderate physical activity (MPA). Options for increasing MPA in community dwelling adults with ADRD and their caregivers are limited. A home-based physical activity intervention delivered remotely via video conferencing to groups of adults with ADRD and their caregivers (RGV), represents a potentially effective approach for increasing MPA in this group. We will conduct an 18-month randomized trial (6 mos. Active intervention, 6 mos. Maintenance, 6 mos. no contact) to compare the effectiveness of the RGV approach with usual care, enhanced with caregiver support (EUC), for increasing MPA in 100 community dwelling adults with ADRD and their caregiver. The primary aim is to compare MPA (min/wk.), assessed by accelerometer, across the 6-mo. active intervention in adults with ADRD randomized to RGV or EUC. Secondarily, we will compare adults with ADRD and their caregivers randomized to RGV or ECU on the following outcomes across 18 mos.: MPA (min/wk.), sedentary time (min/wk.), percentage meeting 150 min/wk. MPA goal, functional fitness, activities of daily living, quality of life, residential transitions, cognitive function, and caregiver burden. Additionally, we will evaluate the influence of age, sex, BMI, attendance (exercise/support sessions), use of recorded sessions, self-monitoring, peer interactions during group sessions, caregiver support, type and quality of dyadic relationship, and number of caregivers on changes in MPA in adults with ADRD and their caregiver across 18 mos.

A Comprehensive Model of Factors Associated With Capability to "Live Well" for Family Caregivers of People Living With Mild-to-Moderate Dementia: Findings From the IDEAL Study

Supplemental Digital Content is available in the text.

Introduction:

Understanding key influences on outcomes for caregivers of people with dementia is hampered by inconsistent conceptualization and measurement of outcomes and limited evidence about the relative impact of different variables. We aimed to address these issues.

Methods:

We analyzed data from 1283 caregivers of community-dwelling individuals with mild-to-moderate dementia in the Improving the experience of Dementia and Enhancing Active Life cohort study. We generated a “living well” latent factor from measures of quality of life, satisfaction with life, and well-being. We used structural equation modelling to derive latent variables for 7 domains reflecting caregivers’ perceptions of their personal resources and experiences, and to examine the associations with caregivers’ perceptions of their capability to “live well.”

Results:

The domain of psychological characteristics and psychological health was most strongly related to living well [2.53; 95% confidence interval (CI), 2.08-2.97], followed by physical fitness and physical health (1.48; 95% CI, 1.04-1.91) and experiencing caregiving (1.34; 95% CI, 0.99-1.70). Social capitals, assets and resources (0.68; 95% CI, 0.35-1.00) and relationship with the person with dementia (−0.22; 95% CI, −0.41 to −0.03) had smaller, significant associations. Social location (0.28; 95% CI, −0.33 to 0.89) and managing everyday life with dementia (0.06; 95% CI, −0.15 to 0.28) were not significantly associated with living well.

Discussion:

These findings demonstrate the importance of supporting caregivers’ psychological and physical health and their ability to develop and maintain positive coping strategies, as well as enabling them to maintain vital social capitals, assets and resources.

Cost-Effectiveness and Effects of a Home-Based Exercise Intervention for Female Caregivers of Relatives with Dementia: Study Protocol for a Randomized Controlled Trial

Previous research has proposed a range of support interventions to mitigate the adverse impact of caregiving on the daily life of caregivers of relatives with dementia. However, the effectiveness of these interventions shows a high variability. Informal caregivers usually lack the time and/or live too far from conventional facilities to do physical exercise, especially those who live in rural areas. Thus, home-based interventions may be more efficacious due to their greater convenience for this population. The present work proposes and describes a study protocol for a randomized control trial that will analyze the efficacy and cost-effectiveness of a home-based, structured individual physical exercise intervention to improve the health-related quality of life and the mental health of female informal caregivers of relatives with dementia. The nine-month-long intervention will comprise participation in two supervised physical exercise sessions per week at the caregiver’s home. The proposed study outcomes will be: (1) feasibility of and adherence to the home-based provision of the intervention; (2) improvement in physical fitness and quality of life; and (3) reduction in subjective burden, psychological symptomatology and depression. Analyses will also be performed to determine the cost-effectiveness after the intervention. In conclusion, this intervention might thus represent a tailored and feasible strategy to help caregivers cope with the physical and psychological stress resulting from caregiving-related responsibilities, and it could represent a novel cost-effective support home-based intervention for caregivers.

Psychological Symptomatology in Informal Caregivers of Persons with Dementia: Influences on Health-Related Quality of Life

Informal caregivers of persons with dementia often report high levels of anxiety, depression and burden. Nonetheless, other less evaluated psychological symptoms might also influence their health-related quality of life (HRQoL). The aim of this study was to comprehensively analyse other psychological symptoms and their influence on the health-related quality of life of informal caregivers. Fifty-four informal women caregivers and fifty-six women non-caregivers were recruited to participate in the study. Psychological symptoms were assessed using the Symptom Check-List-90-Revised (SCL-90-R) questionnaire and the HRQoL with the EuroQoL-Five Dimensions and Three Levels (EurQoL-5D-3L) questionnaire. Significant between-group differences were found in the majority of scales in the SCL-90-R questionnaire (p < 0.01) and caregivers also reported a worse HRQoL than non-caregivers (p < 0.05). Several psychological symptoms such as obsession-compulsive (β = 0.47), hostility (β = 0.59), and somatization (β = −0.49) had a significant impact on caregivers’ HRQoL (R² explained between 0.17 and 0.30 of the variance). Caregivers are at a higher risk of suffering other psychological symptoms and show a moderate–high level of psychiatric morbidity, which therefore explains the poorer HRQoL outcomes. Supporting interventions should be provided to mitigate these psychological symptoms in order to improve their general distress and HRQoL.

Occupational Factors Associated with Health-Related Quality of Life in Nursing Professionals: A Multi-Centre Study

Background: Nursing professionals are exposed to stressful situations arising from the work context that may affect health-related quality of life (HRQoL). The objective of this study was to analyse the relationship between sociodemographic and work-related variables regarding HRQoL in nursing professionals. Methods: A multi-centre, cross-sectional descriptive design was used. The participants consisted 1521 nurses working in healthcare centres, in both primary care and hospital care, in the eight provinces of the Andalusian Public Health System (APHS), Spain. Sociodemographic and work-related variables were analysed: Compassion fatigue, compassion satisfaction and burnout were measured using the professional quality of life questionnaire (ProQOL), and HRQoL was measured using the SF-12 health questionnaire. Results: Compassion fatigue, burnou, and, to a lesser extent, compassion satisfaction significantly influence the physical and mental components of HRQoL. The simple regression analysis showed that burnout and compassion fatigue were significantly associated with the mental component of HRQoL. Gender influenced the mental component of HRQoL. The rest of the sociodemographic and work-related variables were not significantly related to HRQoL. Conclusion: Work-related stress and repeated contact with situations of suffering influence HRQoL. Health systems must implement programmes to increase the emotional well-being of workers.

Mood, lifestyle and cardiovascular risk factors among older caregivers of patients with Alzheimer's disease dementia: a case-control study

BACKGROUND

Caregivers may have a higher risk of cardiovascular diseases and have high rates of anxiety and depression.

AIMS

The objective of this study was to evaluate mood, lifestyle and the presence of cardiovascular risk factors in older women caregivers of patients with Alzheimer´s disease (AD) dementia compared to non-caregivers living in the neighborhood.

METHODS

Paired case-control (1:1). Volunteers responded to a questionnaire with information about physical and leisure activities, smoking, alcohol use, and daily hours of care. Blood pressure (BP) was measured on 5 days with the Home Blood Pressure Monitoring (HBPM) system, and mood was assessed with the Geriatric Depression Scale (GDS) and Mini International Neuropsychiatric Interview (MINI). Laboratory testing for cardiovascular risk factors was performed.

RESULTS

Sixty-two volunteers were evaluated. Total cholesterol levels were higher among caregivers, with an odds ratio (OR) of 3.57 (95% CI 1.2-11, p = 0.03). There was no difference in BP. A positive screening for depression was obtained for 58% of caregivers and for 16% of control subjects (OR = 6.62, 95% CI 1.9-22.6, p < 0.01). The MINI revealed that 38.7% of caregivers had an actual depressive episode as compared to 9.7% of controls (9.7%) (OR = 5.42, 95% CI 1.3-22.7, p = 0.02); 35.5% of caregivers and 6% of controls had a diagnosis of anxiety disorder (OR = 4.79, 95% CI 1.2-19.1, p = 0.03).

DISCUSSION

The cardiovascular risk markers and lifestyle were similar in caregivers and non-caregivers, but there was a higher prevalence of depression and anxiety among caregivers.

CONCLUSIONS

Older women caregivers of patients with AD have more mental health symptoms and disorders and need to be treated.

Emotional Exhaustion in Housewives and Alzheimer Patients' Caregivers: Its Effects on Chronic Diseases, Somatic Symptoms and Social Dysfunction

Background: Emotional exhaustion causes adverse effects in those who suffer from it. Housewives are not excluded. Domestic and care chores, which are considered to be sources of stress, increase when taking on the role of caregiver for a family member with Alzheimer’s disease. Objective: To analyse the influence of emotional exhaustion, somatic symptoms and social dysfunction, based on the activity they carry out. Methodology: Cross-sectional survey. 193 women participated, of which: housewives (HWs) (n = 97), and Alzheimer’s patient caregiver-housewives (CHWs) (n = 96). The evaluation tools were: sociodemographic/working data questionnaire (ad hoc), Maslach Burnout Inventory (MBI) and Goldberg General Health Questionnaire (GHQ-28). Results: High rates of emotional exhaustion are observed, as well as an existing positive link between chronic diseases, somatic symptoms and social dysfunction. The structural model indicates that emotional exhaustion predicts the amount and extent of diseases, somatic symptoms and social dysfunction. The influence is higher in CHWs. Limitations: Sample procedure implemented at convenience; the variable of the grade of dependence of the Alzheimer’s patient caregiver was not included in the study. Conclusions: The domestic and care chores that HWs and CHWs carry out affect their health. Hence the need to develop psychoeducative programmes that are adapted to the particular needs of these women and focused on the different areas of their everyday lives.

The Feasibility of Remotely Delivered Exercise Session in Adults With Alzheimer's Disease and Their Caregivers

Adults with Alzheimer's disease (AD) and their caregivers represent a segment of the population with low levels of moderate-intensity physical activity (MPA) and limited options for increasing MPA. The purpose of this study was to evaluate the feasibility of a group video conference approach for increasing MPA in adults with AD and their caregivers. Adults with AD and their caregivers attended 30-min group exercise sessions three times per week for 12 weeks. Exercise sessions and support sessions were delivered in their homes on a tablet computer over video conferencing software. Nine adults with AD/caregiver dyads enrolled, and seven completed the 12-week intervention. Adults with AD attended 77.3% of the group exercise sessions, and caregivers attended 79.2% of group exercise sessions. Weekly MPA increased in both adults with AD (49%) and caregivers (30%). Exercise delivered by group video conferencing is a feasible and potentially effective approach for increasing MPA in adults with AD and their caregivers.

[Alzheimer's disease and the quality of life of the informal caregiver]

BACKGROUND

Along with an ageing population, a higher incidence of chronic diseases leads to increasingly complex health profiles. The relationship between survival, dependence, and social and demographic trends affecting caregiving, has led to an increase in the negative consequences associated with care provision. In this context, an assessment needs to be made on the impact that caregiving has on the well-being of the caregivers. The main aim of this article is to study the factors that determine the Quality of Life (QoL) of those who provide informal care to people suffering from Alzheimer's disease (AD).

METHODS

A total of 175 caregivers of people with AD were recruited through the Galician Association for Relatives with Alzheimer. These caregivers completed a questionnaire (EQ-5D) that gathered sociodemographic and health variables, QoL, and care characteristics. Multiple regression models were calculated to explain the QoL of the caregivers.

RESULTS

Of the five dimensions that the EQ-5D used to describe health, anxiety/depression was the one that concerned the largest percentage of caregivers who declared the highest levels of severity. The key variables for explaining QoL are those related to caregiver health status, periods of rest during caregiving, and the presence of a second caregiver.

CONCLUSIONS

Maintaining a minimal QoL among the caregivers not only has repercussions on the caregivers themselves, but also has an impact on those receiving care and the entire health system, which would have to find replacements for those informal caregivers.
