Caregiving and older Japanese adults: lessons learned from the periodical literature

Burden of caring for Alzheimer's disease or dementia patients in Japan, the US, and EU: results from the National Health and Wellness Survey: a cross-sectional survey

AIMS

The growing prevalence of Alzheimer's disease (AD) worldwide has sparked the implementation of national policies to support the growing burden among caregivers of AD/dementia patients. This study aims to quantify and compare the burden of AD/dementia caregivers and evaluate how different living arrangements might impact health outcomes among caregivers in Japan, five European countries (5EU), and the United States (US).

MATERIALS AND METHODS

This is a cross-sectional study based on existing data from the 2018 National Health and Wellness Survey. Health outcome measures included health-related quality of life (HRQoL), health state utilities, work productivity and activity impairment (WPAI), and measurement of depression and anxiety amongst AD/dementia caregivers and non-caregivers. Pairwise comparisons between AD/dementia caregivers in Japan, 5EU, and the US were conducted. Multivariate analysis was used to compare across groups within each region, with adjustment for potential confounding effects.

RESULTS

A higher proportion of caregivers of AD/dementia patients in Japan were 65 years or older as compared to 5EU and US. On the contrary, female caregivers were significantly higher in the US than Japan and 5EU. The HRQoL and health state utilities index scores amongst AD/dementia caregivers were highest in Japan and lowest in the US. Caregivers in Japan incurred the lowest WPAI among the three regions. The proportion of AD/dementia patients reportedly living in an institution was highest in Japan as compared to the US and EU. Notably, US caregivers whose patients lived in an institution experienced significantly less caregiving burden as compared to caregivers whose patients lived in the community.

CONCLUSIONS

The caregiving burden among AD/dementia caregivers was substantial across the three regions, with similarities and differences between the West and Japan. The lower caregiving burden in Japan was potentially associated with national policies supporting long-term healthcare and institutionalized nursing care facilities for AD/dementia patients.

Association of Filial Responsibility, Ethnicity, and Acculturation Among Japanese American Family Caregivers of Older Adults

Challenges of filial caregiving practices by 1st-generation immigrants due to differences in caregiving values between their home and host countries are well documented. This study explored the filial responsibility of later generation Japanese American caregivers of older adults. Acculturation and filial responsibility were measured using the Suinn-Lew Asian Self Identity Acculturation scale and Filial Values Index, respectively. A qualitative interview guide was developed using Gordon's assimilation theory, and 21 caregivers ( M age = 68 years, 86% female, seven in each generation) were interviewed. Despite the 3rd-generation caregivers' high acculturation level, their filial responsibility scores remained high. Qualitative interviews also revealed later generation caregivers' strong filial responsibility and continued caregiving involvement. Unexpectedly, caregivers' own future expectancy of care included placement in mainstream residential facilities rather than ethnic-specific settings. Findings point to the need to develop caregiver services that consider later generation caregivers' culture and level of assimilation.

Depression among family caregivers of community-dwelling older people who used services under the Long Term Care Insurance program: a large-scale population-based study in Japan

OBJECTIVE

To identify predictors for depression among family caregivers of community-dwelling older people under the Long Term Care Insurance (LTCI) program in Japan through a large-scale population-based survey.

METHOD

All 5938 older people with disabilities, using domiciliary services under the LTCI in the city of Toyama, and their family caregivers participated in this study. Caregiver depression was defined as scores of ≥16 on the Center for Epidemiological Studies Depression Scale (CES-D). Other caregiver measures included age, sex, hours spent caregiving, relationship to the care recipient, income adequacy, living arrangement, self-rated health, and work status. Care recipient measures included age, sex, level of functional disability, and severity of dementia. The data from 4128 pairs of the care recipients and their family caregivers were eligible for further analyses. A multiple logistic regression analysis was used to examine the predictors associated with being at risk of clinical depression (CES-D of ≥16).

RESULTS

Overall, 34.2% of caregivers scored ≥16 on the CES-D. The independent predictors for depression by logistic regression analysis were six caregiver characteristics (female, income inadequacy, longer hours spent caregiving, worse subjective health, and co-residence with the care recipient) and one care-recipient characteristic (moderate dementia).

CONCLUSION

This is one of the first population-based examinations of caregivers of older people who are enrolled in a national service system that provides affordable access to services. The results highlighted the importance of monitoring caregivers who manifest the identified predictors to attenuate caregiver depression at the population level under the LTCI.

A Review of Ethnicity, Culture, and Acculturation Among Asian Caregivers of Older Adults (2000-2012)

This review identified domains of care experiences among studies of Chinese, Filipino, Japanese, Korean, and Vietnamese caregivers in the United States and Canada between 2000 and 2012. Using a narrative approach, 46 peer-reviewed journal articles were found through electronic databases and references. Considering caregivers' assimilation to host countries, attention was given to their culture, socioeconomic resources, immigrant status, filial responsibility, generation, and acculturation. Three primary domains were identified across subgroups. The caregivers' experiences domain was a strong sense of filial responsibility and its varied effects on caregiving experience; in the cultural values domain, reciprocity, and familism. In the acculturation domain, caregivers' generations influenced their experiences. Because our society is rapidly changing demographically and culturally, studies of older adults and their caregivers that are not only inclusive of all racial/ethnic groups but also sensitive to specific racial/ethnic and cultural subgroup differences are necessary to inform policy and practice.

Memory banking: a life story intervention for aging preparation and mental health promotion

OBJECTIVE

The aim of this study is to examine the feasibility of Memory Banking (MB), a life story development intervention within the context of aging preparation. Individuals participate in MB to strategically document and share their life story, including mapping out future dreams, aspirations, plans, and decisions.

METHOD

Data (2010-2012) from eight MB workshops were examined to determine the impact of the intervention on mental health, social support, and quality of life.

RESULTS

Recruitment efforts resulted in n = 72 participants, primarily female (72%), White/Caucasian (93%), average age of 70 years. Data indicated intervention effects showing improvements in depression (p = .041), mood disturbance (p = .0067), and cognitive performance (p = .0045).

DISCUSSION

MB outcomes indicate that the intervention is promising and supports continued investigation and development in the area of life story development for aging preparation and improving late life mental health distress in a community setting. Future research is needed to examine the versatility and long-term effects of the MB intervention.
