Mothers and daughters-in-law: a prospective study of informal care-giving arrangements and survival in Japan

Examining the impact of Co-residence with a daughter-in-law on older adult health in China: Evidence from a frailty index-based study

Background

The increasing geriatric population and variation in the disease spectrum among older adults in China contribute to a growing demand for more aged adult care in Chinese society. Relevant studies have shown that living arrangements with various family members have variable impacts on the older adult's health. This study employs the Frailty Index as a unified measurement standard to assess the overall health levels, integrating the specific "in-law relationships" into the research on living arrangements and the health of older adults.

Methods

This study used data from the China Longitudinal Aging Social Survey 2016-2018. OLS and Quantile Regression were used to investigate the in-law relationship on older adult health and whether this impact is homogeneous across older individuals with varying infirmity levels. The study used a lag model and propensity score matching to compensate for potential endogeneity concerns.

Results

The study found that residing with a daughter-in-law (20.22%) had a significant positive correlation with the frailty index (β=0.0088, P＜0.001), indicating that the relationship between parents-in-law and daughters-in-law can influence the health of the older adult. This impact is nonlinear and non-homogeneous for older adult people with various levels of frailty, exhibiting an approximately decreasing and then increasing U-shaped distribution, which denotes that older adult people with different health conditions have distinct demands for intergenerational care. In addition, this impact varies among older adult groups of disparate genders, urban and rural areas, and age groups.

Conclusion

This study investigates the impact of "in-law relationships" within living arrangements on the health of older adults. It shows that co-residing with a daughter-in-law has adverse effects on the health of older adults. Therefore, the study suggests that when the health and economic conditions of the elderly permit, a "live-near-but-not-with" living arrangement with their children can be considered.

Association between caregivers' health-related quality of life and care recipients' health outcomes

AIMS

This study aimed to investigate the relationship between family caregivers' health-related quality of life and health outcomes in care recipients.

METHODS

A total of 160 female caregivers in Japan were initially assessed using self-reported baseline questionnaires to determine physical and mental aspects of their health-related quality of life. Based on these scores, they were divided into three groups: lower, middle, and higher quality of life. We followed up with the 133 participants (after excluding those that did not respond) 6 years later to assess the health of their care recipients; 36 caregivers continued to provide home care, while 97 reported that their care recipient had died or been admitted into institutionalized care.

RESULTS

Statistically, a higher risk for care recipients' health deterioration was strongly associated with the mental component score in the lower caregivers' quality of life group of than for the middle group, after adjusting for the care recipients' age, health status, and caregivers' age at baseline. There was no significant association between deterioration of health of care recipients and physical component scores of the caregivers.

CONCLUSION

Caregivers' poor health-related quality of life, particularly poor mental health, may be linked to the deterioration of care recipients' health.

In-Law Relationships in Evolutionary Perspective: The Good, the Bad, and the Ugly

In-laws (relatives by marriage) are true kin because the descendants that they have in common make them "vehicles" of one another's inclusive fitness. From this shared interest flows cooperation and mutual valuation: the good side of in-law relationships. But there is also a bad side. Recent theoretical models err when they equate the inclusive fitness value of corresponding pairs of genetic and affinal (marital) relatives-brother and brother-in-law, daughter and daughter-in-law-partly because a genetic relative's reproduction always replicates ego's genes whereas reproduction by an affine may not, and partly because of distinct avenues for nepotism. Close genetic relatives compete, often fiercely, over familial property, but the main issues in conflict among marital relatives are different and diverse: fidelity and paternity, divorce and autonomy, and inclinations to invest in distinct natal kindreds. These conflicts can get ugly, even lethal. We present the results of a pilot study conducted in Bangladesh which suggests that heightened mortality arising from mother-in-law/daughter-in-law conflict may be a two-way street, and we urge others to replicate and extend these analyses.

Association between primary caregiver type and mortality among Chinese older adults with disability: a prospective cohort study

Background

Socio-demographic transitions have dramatically changed the traditional family care settings in China, caused unmet care needs among older adults. However, whether different primary caregiver types have different influences on disabled older adults’ health outcomes remain poorly understood. We aimed to examine the association between the type of primary caregiver (e.g., spouse and children) and death among community-dwelling Chinese older adults disabled in activities of daily living.

Methods

We used data from Chinese Longitudinal Healthy Longevity Survey. The analytic sample comprised 4278 eligible adults aged ≥ 80 years. We classified primary caregiver type into five categories: spouse, son/daughter-in-law, daughter/son-in-law, grandchildren, and domestic helper. We used Cox regression model to examine the association between primary caregiver type and all-cause mortality. Covariates included age, sex, residence, years of education, co-residence status, financial independence, whether living with children, number of ADL disability, number of chronic conditions, and self-reported health, cognitive impairment, and caregiving quality.

Results

Married older adults whose primary caregivers were son/daughter-in-law had a 38% higher hazard of death than those who had spouse as the primary caregiver. Married men who received care primarily from son/daughter-in-law or daughter/son-in-law had a 64 and 68% higher hazard of death, respectively, than those whose primary caregiver was spouse. The association between primary caregiver type and mortality among widowed older adults differed between urban and rural areas. Urban residents who had domestic helpers as the primary caregiver had an 16% lower hazard of death, while those living in rural areas had a 50% higher hazard of death, than those having son/daughter-in-law as the primary caregiver.

Conclusions

The quality of care of the primary caregiver may be a risk factor for mortality of disabled older adults in China. Interventions are necessary for reducing unmet needs and managing care burden.

Relationship of living arrangement with the decline in functional capacity in elderly people by gender: a longitudinal observational study

Background

The living arrangement has been suggested as an important factor affecting health. Recent studies have also suggested that there was a risk among elderly persons who were not alone. This study examined whether the detailed living arrangement was associated with a future decline in functional capacity in the elderly, by gender, in a Japanese suburban city.

Methods

A 3-year longitudinal questionnaire survey (baseline: 2011; follow-up: 2014) for aged 65 years or older was conducted in Kurihara city, Japan. Of the respondents in the baseline survey, we analyzed those who scored 13 points (a perfect score which indicates the highest functional capacity; n = 2627) on the Tokyo Metropolitan Institute of Gerontology Index of Competence at the baseline. The exposure was living arrangement at baseline, divided into five categories: “with spouse only,” “living alone,” “with child and his/her spouse,” “with child without his/her spouse,” and “with other family/person.” The outcome was the decline in functional capacity at the follow-up survey (score decreased to 10 points or less from 13 points).

Results

Of the 2627 analyzed population, 1199 (45.6%) were men. The incidence of the decline was 5.8% in men and 5.9% in women. Multivariable logistic regression analyses adjusted for age, educational attainment, and health behavior and condition revealed that in women, the odds ratio of the decline was higher in living with child and his/her spouse (2.41, 95% confidence interval; 1.10–5.28) referring to living with spouse only. When adjusting activities inside and outside the home such as housework additionally, the association was attenuated to marginal significance (2.25, 0.98–5.18). No statistical significance was observed in men.

Conclusions

These results suggested that living with child and spouse of a child was associated with the future decline in women’s functional capacity.

Care inequality: care received according to gender, marital status, and socioeconomic status among Korean older adults with disability

Background

We sought to identify the types of care and care resources available to older Korean adults with disabilities, and document the inequality in care received according to gender, marital status, and socioeconomic status.

Method

Data were derived from the sixth wave of the Korean Longitudinal Study of Ageing. The sample consisted of 946 men and women who were disabled in ADL and IADL. Generalized linear models and analyses of covariance were used to evaluate group differences in types of care received and care resources. The outcome variables were main primary caregivers, the total number of available caregivers, hours of care received per day, number of days of care, and fees paid to caregivers.

Results

In total, 41.7% of men with ADL/IADL disabilities reported that they did not receive formal or informal care from any source, compared with 30.7% of women. Almost half (49.2%) of men without a spouse were in a state of care deficit (vs. 30.8% in women without a spouse, P < 0.001). Among care recipients, men reported receiving higher average days of care per month than women (25.6 vs. 21.2 days, P < 0.01). Both men and women received care primarily from their spouse, but adult children were more frequently care providers for older women than men. A combination of care from spouse and paid caregiver was more frequent among women. Dependent older people with high household incomes had a higher likelihood of receiving care There was the clear gradient in rate of paid formal caregivers use by household income (higher income = higher use) among women but not men.

Conclusions

Care types and resources among disabled older adults appeared to be different by gender, marital status and socioeconomic status under the cultural phenomenon and contextual circumstances in the aging Korean population.

Living with parents or grandparents increases social capital and survival: 2014 General Social Survey-National Death Index

INTRODUCTION

After nearly a century-long trend toward single-family living arrangements, people in wealthy nations are increasingly living in multi-generational households. Multi-generational living arrangements can, in theory, increase psychological, social, and financial capital-factors associated with improvements in health and longevity.

METHODS

We conducted a survival analysis using the 2014 General Social Survey-National Death Index, a prospective multi-year survey. We explored whether single generational living arrangements were associated with a higher risk of mortality than multi-generational living arrangements.

RESULTS

We explored this association for different groups (e.g., the foreign-born and those with high self-reported stress in family relationships). Healthy subjects who live in two-generation households were found to have lower premature mortality (hazard ratio 0.9, 95% confidence interval = 0.82, 0.99). Otherwise, we found little evidence that living arrangements matter for the respondents' risk of premature mortality.

CONCLUSIONS

Healthy people living in two-generation households have longer survival than healthy people living on their own.

Differences in caregivers' psychological distress and associated factors by care recipients' gender and kinship

OBJECTIVES

In this study, we examined the level of psychological distress of Japanese caregivers according to various combinations of the gender of care recipients and the kinship of caregivers (spouse, son, daughter, or daughter-in-law). Furthermore, we explored the associated factors that could exacerbate or alleviate psychological distress.

METHODS

We utilized a cross-sectional descriptive design and implemented a self-administered questionnaire survey with a two-stage stratified sample of community-dwelling caregivers of frail elderly persons throughout Japan. We surveyed 1279 caregiving families, and 1020 questionnaires were completed by primary caregivers (response rate: 79.8%), with 945 respondents providing data on the Japanese version of the Kessler 6 psychological distress scale (K6).

RESULTS

Caregivers' K6 scores varied significantly by care recipients' gender and their relationship with the caregiver. K6 scores were significantly higher among daughters-in-law caring for fathers-in-law than among daughters-in-law caring for mothers-in-law, wives caring for husbands, or daughters or sons caring for mothers. 'Negative influence of caregiving' and 'anxious about continuing caregiving' were factors that commonly exacerbated caregivers' psychological distress. Further analyses involving interactions indicated that the effects of 'anxious about continuing caregiving' and 'personal growth through caregiving' on the psychological distress of daughters-in-law varied by care recipients' gender as did the effects of an alleviating factor, 'keeping their own pace', on daughters.

CONCLUSIONS

Psychological distress levels among family caregivers, as well as exacerbating and alleviating factors, varied depending on the gender and kinship of care recipients.

Women's Experiences Caring for Their Husbands' Siblings With Developmental Disabilities

A phenomenological method was used in this study to examine the experiences of women caring for the husband’s sibling with developmental disabilities (DDs) with the aim of establishing how and why they came to care and continued to care for them. Three themes emerged after drawing on stories shared by seven women: for the sake of my husband, powerlessness, and trade-off between cost and rewards. The findings of this study show that Taiwanese women accept the cultural norms, thus accepting the caregiving responsibility. Reciprocity did not help determine whether women started caring for the husband’s sibling with DD. However, when an imbalance in reciprocity is present, women experience negative emotions that often result in tension within the family. Positive factors contributed by the husband and parents-in-law can facilitate the work of caregivers by ameliorating physical pain and psychological distress that can occur during the caregiving process.

Psychological distress among tsunami refugees from the Great East Japan earthquake

BACKGROUND

The 2011 Great Japan tsunami and nuclear leaks displaced 300 000 people, but there are no large studies of psychological distress suffered by these refugees.

AIMS

To provide a first assessment of major factors associated with distress and dysfunctional behaviour following the disasters.

METHOD

All refugee families living in Miyagi were sent a questionnaire 10-12 months after the disasters. 21 981 participants (73%) returned questionnaires. Questions assessed psychological distress (Kessler Psychological Distress Scale, K6), dysfunctional behaviours, demographics, event exposure, change in physical activity, household visitors and emotional support.

RESULTS

Nine percent scored 13+ on the K6 indicating risk of severe mental illness. Psychological distress was greater among Fukushima refugees. Demographic variables, family loss, illness history and change in physical activity were associated with psychological distress and dysfunctional behaviours. Associations between psychological distress and dysfunction and visitors/supporters depended on relation to supporter.

CONCLUSIONS

Practitioners need to recognise existing disease burden, community histories and family roles when intervening following disasters.

A gap in formal long-term care use related to characteristics of caregivers and households, under the public universal system in Japan: 2001-2010

We investigated whether the universal provision of long-term care (LTC) under Japan's public system has equalized its use across households with different socio-economic characteristics, with a special focus on the gender and marital status of primary caregivers, and income. We used repeated cross-sectional data from national household surveys (2001, 2004, 2007, and 2010) and conducted multiple logistic regression analyses to obtain odds ratios of caregiver and household characteristics for service use, adjusting for recipients' characteristics. The results showed that the patterns of service use have been consistently determined by caregivers' gender and marital status over the period despite demographic changes among caregivers. The gap in service use first narrowed, then widened again across income levels after the global economic recession. The results indicate that the traditional gender-bound norms and capacity constraints on households' informal care provision remained influential on decisions over service use, even after the universal provision of formal care. To improve equality of service utilization, the universal LTC system needs to meet diversifying needs of caregivers/recipients and their households, by overcoming barriers related to gender norms and economic disparity.

Knowledge, perceptions, and experiences of family caregivers and home care providers of physical restraint use with home-dwelling elders: a cross-sectional study in Japan

BACKGROUND

The use of physical restraints by family caregivers with home-dwelling elders has not been extensively studied but it might be widespread. Furthermore, it is also not clear how home care providers who support family caregivers perceive the use of physical restraint in elders' homes. This study assessed family caregivers' and home care providers' knowledge and perceptions of physical restraint used with elders living at home in Japan, a country with the highest proportion of elders in the world and where family caregiving is common.

METHODS

We undertook a cross-sectional study of 494 family caregivers, 201 home helpers, 78 visiting nurses, 131 visiting physicians, and 158 care managers of home-dwelling frail elders needing some care and medical support in Japan, using questionnaires on knowledge of 11 physical restraint procedures prohibited in institutions and 10 harmful effects of physical restraints, perceptions of 17 reasons for requiring physical restraints, and experiences involving physical restraint use.

RESULTS

Family caregivers were aware of significantly fewer recognized prohibited physical restraint procedures and recognized harmful effects of physical restraint than home care providers, and differences among home care providers were significant. The average importance rating from 1 (least) to 5 (most) of the 17 reasons for requiring physical restraints was significantly higher among family caregivers than home care providers, and significantly different among the home care providers. Moreover, these differences depended in part on participation in physical restraint education classes. While 20.1% of family caregivers had wavered over using physical restraints, 40.5% of home care providers had seen physical restraints used in elders' homes and 16.7% had advised physical restraint use or used physical restraints themselves.

CONCLUSIONS

Knowledge and perceptions of physical restraints differed between family caregivers and home care providers and were also diverse among home care providers. Because both groups might be involved in physical restraint use with home-dwelling elders, home care providers should acquire standardized and appropriate knowledge and perceptions of physical restraints to help family caregivers minimize abusive physical restraint use.

Physical and mental health among caregivers: findings from a cross-sectional study of Open University students in Thailand

BACKGROUND

Caregivers constitute an important informal workforce, often undervalued, facing challenges to maintain their caring role, health and wellbeing. Little is known about caregivers in middle-income countries like Thailand. This study investigates the physical and mental health of Thai adult caregivers.

METHODS

This report derives from distance-learning students working and residing throughout Thailand and recruited for a health-risk transition study in 2005 (N=87,134) from Sukhothai Thammathirat Open University. The cohort follow-up questionnaire in 2009 (N = 60,569) includes questions on caregiver status which were not available in 2005; accordingly, this study is confined to analysis of the 2009 data. We report cross-sectional associations between caregiver status and health.

RESULTS

Among the study participants in 2009, 27.5% reported being part-time caregivers and 6.6% reported being full-time caregivers. Compared to male non-caregivers, being a part-time or full-time male caregiver was associated with lower back pain (covariate-Adjusted Odds Ratios, AOR 1.36 and 1.67), with poor psychological health (AOR 1.16 and 1.68), but not with poor self-assessed health. Compared to female non-caregivers, being a part- or full-time female caregiver was associated with lower back pain (AOR 1.47 and 1.84), psychological distress (AOR 1.32 and 1.52), and poor self-assessed health (AOR 1.21 and 1.34).

CONCLUSIONS

Adult caregivers in Thailand experienced a consistent adverse physical and mental health burden. A dose-response effect was evident, with odds ratios higher for full-time caregivers than for part-time, and non-caregivers. Our findings should raise awareness of caregivers, their unmet needs, and support required in Thailand and other similar middle-income countries.

Population ageing and wellbeing: lessons from Japan's long-term care insurance policy

Japan's population is ageing rapidly because of long life expectancy and a low birth rate, while traditional supports for elderly people are eroding. In response, the Japanese Government initiated mandatory public long-term care insurance (LTCI) in 2000, to help older people to lead more independent lives and to relieve the burdens of family carers. LTCI operates on social insurance principles, with benefits provided irrespective of income or family situation; it is unusually generous in terms of both coverage and benefits. Only services are provided, not cash allowances, and recipients can choose their services and providers. Analysis of national survey data before and after the programme started shows increased use of formal care at lower cost to households, with mixed results for the wellbeing of carers. Challenges to the success of the system include dissatisfaction with home-based care, provision of necessary support for family carers, and fiscal sustainability. Japan's strategy for long-term care could offer lessons for other nations.
