A longitudinal analysis of the impact of family support on the morale of older parents in Japan: does the parent's normative belief in filial responsibilities make a difference?

Developing a scale for examining the perspective of university students on parental care

Introduction

With the declining birth rate and increasingly aging population in Japan, an increased care burden may be placed on the family and the younger generation will address challenging circumstances when they can care for their parents. This study aimed to develop a scale for examining the perspectives of Japanese university students on parental care and determines its reliability and validity.

Methods

A web-based survey on a total of 408 Japanese students was adopted. This study performed exploratory and confirmatory factor analyses to obtain the underlying factors of the scale. Reliability was verified using Cronbach's α coefficient and Spearman-Brown's split-half reliability α coefficient. Validity was verified through sample, criterion-related, and convergent and discriminant validity.

Results

In total, the study identified a three-factor 11 item-scale. Cronbach's α for the scale was 0.901, and the Cronbach's α and split-half reliability α coefficients of each factor were greater than 0.7. Three factors explained 64.6% of the total variance. The model indicators were χ2/df = 2.241, comparative fit index (CFI) = 0.951, incremental fit index (IFI) = 0.951, TLI = 0.942, root mean square error of approximation (RMSEA) = 0.078 (p < 0.001). Thus, the study confirmed that the convergent and discriminant validity is acceptable. Correlations were noted for criterion-related validity (r = 0.675, p < 0.001).

Discussion

The results show that the scale for examining the perspective of Japanese university students on parental care was confirmed with good reliability and validity.

The role of family communication patterns in intergenerational COVID-19 discussions and preventive behaviors: a social cognitive approach

BACKGROUND

This study explores and compares the influences of family communication patterns (conversation orientation and conformity orientation) on family discussion and preventive behaviors for older parents and their adult children in the context of the early COVID-19 outbreak.

METHODS

A total of 248 participants, including 117 parents and 131 adult children, participated in an online survey in February 2020. Participants reported family communication patterns, family discussions related to COVID-19, and their preventive behaviors.

RESULTS

Conversation orientation was positively associated with information sharing and scientific discussion for older parents and adult children. Our results revealed the differential influences of conformity orientation on older parents and adult children. Conformity orientation was positively associated with scientific discussion for older parents but was not significantly associated with any form of family discussion reported by adult children. There was a significant interaction effect of conversation orientation and conformity orientation on disputed communication within the family, suggesting that conflicts may arise in COVID-related discussions when parents and adult children value conversation and conformity. Scientific discussion was found to mediate the relationships between family communication patterns and preventive behaviors. The effects of scientific discussions were stronger for older parents than for adult children.

CONCLUSIONS

Family communication patterns can be associated with preventive behaviors through different forms of family discussion about COVID-19. Conversation orientation is a strong facilitator for positive behavioral effects and scientific discussion is the most benign form of family health discussion. Health communication efforts should enhance the agency role of the family and motivate scientific discussion in health practices.

Predictive Models of Life Satisfaction in Older People: A Machine Learning Approach

Studies of life satisfaction in older adults have been conducted extensively through empirical research, questionnaires, and theoretical analysis, with the majority of these studies basing their analyses on simple linear relationships between variables. However, most real-life relationships are complex and cannot be approximated with simple correlations. Here, we first investigate predictors correlated with life satisfaction in older adults. Then, machine learning is used to generate several predictive models based on a large sample of older adults (age ≥ 50 years; n = 34,630) from the RAND Health and Retirement Study. Results show that subjective social status, positive emotions, and negative emotions are the most critical predictors of life satisfaction. The Support Vector Regression (SVR) model exhibited the highest prediction accuracy for life satisfaction in older individuals among several models, including Multiple Linear Regression (MLR), Ridge Regression (RR), Least Absolute Shrinkage and Selection Operator Regression (LASSO), K Nearest Neighbors (KNN), and Decision Tree Regression (DT) models. Although the KNN and DT models exhibited better model fitting than MLR, RR, and LASSO, their performances were poor in terms of model validation and model generalization. These results indicate that machine learning is superior to simple correlations for understanding life satisfaction among older adults.

'Investing' in care for old age? An examination of long-term care expenditure dynamics and its spillovers

We study the dynamic drivers of expenditure on long-term care (LTC) programmes, and more specifically, the effects of labour market participation of traditional unpaid caregivers (women aged 40 and older) on LTC spending, alongside the spillover effects of a rise in LTC expenditure on health care expenditures (HCE) and the economy (per capita GDP). Our estimates draw from a panel of more than a decade worth of expenditure data from a sample of OECD countries. We use a panel vector auto-regressive (panel-VAR) system that considers the dynamics between the dependent variables. We find that LTC expenditure increases with the rise of the labour market participation of the traditional unpaid caregiver (women over 40 years of age), and that such expenditures rise exerts large spillover effects on health spending and the economy. We find that a 1% increase in female labour participation gives rise to a 1.48% increase in LTC expenditure and a 0.88% reduction in HCE. The effect of LTC spending over HCE is mainly driven by a reduction in inpatient and medicine expenditures, exhibiting large country heterogeneity. Finally, we document significant spillover effects of LTC expenditures on per capita GDP.

Intergenerational support and depressive symptoms in old age: The difference between urban and rural China

Objectives

Intergenerational support is associated with fewer depressive symptoms in old age. Uneven development has resulted in huge urban-rural disparities in China, which could lead to different intergenerational relationships. The present study aimed to examine whether intergenerational support was associated with depressive symptoms differently among urban and rural Chinese older participants.

Methods

A sample of 3,498 participants from nine pairs of urban subdistricts and rural villages were included in the present study. Depressive symptoms were measured by the 10-item Center for Epidemiological Studies Depression Scale, and the intergenerational support mechanisms (financial, instrumental, and emotional) were assessed with a self-designed questionnaire.

Results

Significant areas by support effect for depressive symptoms indicated different associations between intergenerational financial and emotional support and depressive symptoms in urban and rural areas. Specifically, urban older participants receiving emotional support from adult children and rural older participants receiving financial support from adult children showed fewer depressive symptoms. In both areas, participants receiving instrumental support showed fewer depressive symptoms.

Conclusion

Our study is the first to compare the urban-rural disparity in association between intergenerational support and depressive symptoms in a developing country, China. The results support modernization theories proposing weakened economic function but intensified emotional ties in societies with higher level of development. Communication-based intergenerational emotional support should be promoted in urban areas, and formal support systems should provide financial and instrumental support to the vulnerable rural older population.

Can social capital moderate the impact of widowhood on depressive symptoms? A fixed-effects longitudinal analysis

OBJECTIVES

Widowhood is associated with increased risks of depression in the surviving spouse. We examined whether an increase in individual-level social capital mitigates the adverse impact of widowhood on depressive symptoms.

METHODS

We used data from the 2013/2016 waves of the Japan Gerontological Evaluation Study of functionally independent adults aged 65 years or older (men: n = 20,853; women: n =16,858). Fixed-effects regression was applied to examine the potential buffering effects of changes in social capital on changes in depressive symptoms following widowhood among married people living with their spouse and/or others at baseline.

RESULTS

Widowhood had a deleterious impact on depressive symptoms particularly among men who ended up living alone following their spouse's death. Fixed-effects models revealed that an increase in informal socializing and social participation might buffer the effects of spousal bereavement on depressive symptoms among men who became widowed during the first two years of follow-up and ended up living alone.

DISCUSSION

An increase in structural social capital may mitigate the impact of spousal bereavement on depressive symptoms. However, the associations vary by gender, living arrangement, and time since widowhood. Intensive efforts should be directed toward connecting the vulnerable group, widowed men living alone, to sources of social capital.

Married Adults Coresiding with Older Parents: Implications for Paid Work and Domestic Workloads

The rise of life expectancy throughout the developed world has meant that older adults play an increasingly important role in their grown-up children's lives. We evaluate whether the intergenerational solidarity theory is useful for understanding the intergenerational transfers of time in Japan given the relatively generous welfare provision for the older adults and the fall in intergenerational coresidence. We apply seemingly unrelated regression models to data of the 2006 Japanese Survey on Time Use and Leisure Activities (Statistics Bureau Japan, 2006) to investigate how coresidence patterns are associated with paid and unpaid work time of adult married children. The sample contains 23,226 married couples where both husband and wife are aged 20 to 59. We find evidence of intergenerational solidarity in coresident households. We also find that "doing gender" is layered through intergenerational exchanges of support between married working-age children and their older parents. Working-age women's time use patterns are associated with coresidence arrangements and care needs of their older relatives to a much greater extent than working-age men's. The observed patterns are consistent with healthy older women supporting their daughters' careers in exchange for care when they need help themselves. For working-age men, the patterns are not very pronounced. Notably, working-age husbands without children appear to be more responsive to their older the parents' care needs, suggesting that fatherhood may be associated with solidifying gendered role performance within Japanese couples.

The Effects of Familial Social Support Relationships on Identity Meaning in Older Adults: A Longitudinal Investigation

This study aimed to examine whether social support promotes identity meaning among older adults. We hypothesized that when two spouses exchange social support, their sense of marital identity is enhanced. Among older adults, parental identity may be more strongly enhanced when parents provide social support to their children rather than receive social support from them. We conducted a longitudinal survey of 355 older adults (240 men and 115 women aged >60 years), who were assessed four times over 2 years. First, we confirmed the relationship between social support and identity meaning using an autoregressive path model. Second, we examined the effect of social support on the trajectory of role identities in a growth curve model. The intercepts of receiving support and providing support were significantly associated with the intercept of marital identity. In addition, the intercept of identity meaning for parents correlated with the intercept of providing support to their children but not with that of receiving support from their children. Social support between family members promotes role identities in family relationships. In particular, providing support to children correlates with parental roles which connect to subjective well-being.

Patterns of family support exchange and personal mastery in later life: a longitudinal study

Objectives: The association between family support exchange and personal mastery among older adults remains unclear. The present study addresses this gap.Methods: We utilized two waves of data from the Panel on Health and Ageing of Singaporean Elderly (N = 1398). Latent class analysis was conducted to identify distinct patterns of family support exchange. Regression analysis was then used to assess whether the identified patterns predicted personal mastery four years later.Results: Four and three prevalent patterns of family support exchange emerged for males and females, respectively. Males who received monetary and material support from their kin developed lower personal mastery than those who only received monetary support. Females who provided and received monetary support developed higher personal mastery than those who lacked support exchange.Conclusion: Our latent class approach has captured the reality of family support exchange and thus provided a valid picture of the implication of such exchange for personal mastery. Our data suggest that support provision may elevate personal mastery. This observation is discussed with reference to the self-enhancement perspective and notion of valence of support provision.

Family social capital and life satisfaction among older adults living alone in urban China: the moderating role of functional health

Objectives: The present study examined the moderating effects of functional health on the association between family social capital and life satisfaction among older adults who live alone in urban China.Method: Data for this study were derived from a study "Survey on older adults aged 70 and above who live alone in urban China," which was carried out in five Chinese cities between November 2013 and May 2015. 2801 respondents passed the screening test of cognitive capacities and successfully completed the survey. Family social capital was operationalized as family interaction, number of children, and family relationship. Random-effects logistic regression was conducted to test the proposed hypotheses.Results: The moderating effects of functional health on the association between family interaction and life satisfaction were identified. While family interaction was positively associated with life satisfaction among older adults without disabilities who live alone, family interaction was negatively associated with life satisfaction among those with disabilities. Furthermore, the association between number of children and life satisfaction was nonsignificant among older adults without disabilities, when family relationship was controlled. However, number of children was positively associated with life satisfaction among those with disabilities. Finally, the results showed family relationship were important protective factors of life satisfaction among older adults living alone, regardless of their functional health levels.Conclusion: Theoretical aspects on how family social capital, living alone, and functional health are interwoven and influence mental health in later life were deliberated. Policy and intervention implications were discussed.

Family Support, Multidimensional Health, and Living Satisfaction among the Elderly: A Case from Shaanxi Province, China

The current study investigated the association between three types of family support and living satisfaction of elderly individuals in China, and paid particular attention to the possible mediating role of the elderly population’s multidimensional health. A cross-sectional survey was conducted in 2019, and 938 elderly people from seven counties (districts) of China’s Shaanxi province were enrolled. Multivariable linear regression and mediation effect analysis were employed to examine the integrated relationships among these variables. The results showed that emotional support and decisional support from families were positively related to the living satisfaction of elderly individuals (β = 0.101, p = 0.000; β = 0.263, p = 0.000), while the relationship between daily living support and living satisfaction was not significant (β = 0.017, p > 0.05). The mediation examination further demonstrated that both mental state and social integration mediated the association between emotional support and living satisfaction, as well as the association between decisional support and living satisfaction, but a mediating effect of physical health was not observed. These results indicate the pathways in the relationships of different types of family support to living satisfaction via mental state and social integration, having significant implications for enhancing the living satisfaction the elderly.

Risk factors of severe prolonged grief disorder among individuals experiencing late-life bereavement in Japan: A qualitative study

This article explored how severe prolonged grief disorder (PGD) is associated with psychological and social variables using an interpretative phenomenological analysis. From a sample of 225 Japanese hospitalized adults with depression, seven participants were identified as having PGD based on their medical records and semi-structured interviews. Risk factors appeared to be psychological factors associated with the deceased (dependence on the deceased, feeling sorry for the deceased, intense self-blame, and infrequent expression of anger) and environmental factors (loneliness and isolation, lack of opportunity to determine separation, and release from practical burdens). These findings are discussed in relation to Japanese culture.

Emotional regulation as a mediator between the filial behaviour of the oldest son and subjective well-being of older parents in Pakistan

BACKGROUND

The link between the filial behaviour of an adult child and older parents' well-being is well entrenched, and theoretical evidence has indicated that it may be mediated by emotional regulation. Therefore, the current study aimed to examine whether emotional regulation (i.e. cognitive reappraisal and suppression) mediates the association between filial behaviour of the oldest son (i.e. the filial behaviour of respect and filial behaviour of daily maintenance) and subjective well-being in older parents.

METHODS

This correlational study recruited 400 community-dwelling older parents in Rawalpindi Pakistan through a multistage cluster random sampling technique. Subjective well-being was measured by Concise Measure of Subjective Well-being; filial behaviour was examined through receipt of 12 domains; emotional regulation was assessed by using the Emotional Regulation Questionnaire. The structural equation modelling was employed to test the mediation effects.

RESULTS

Cognitive reappraisal was found to partially mediate the relationship between filial behaviour of respect and subjective well-being (β in direct model = 0.661, P < 0.000; β in full mediational model = 0.327, P < 0.000), but it failed to mediate between filial behaviour of daily maintenance and subjective well-being (β in direct model = 0.080, P = 0.149; β in full mediational model = 0.030, P = 0.362). Moreover, suppression did not exert mediation effects in the associations between the filial behaviour of respect and subjective well-being (β = 0.003, P = 0.338); and filial behaviour of daily maintenance and subjective well-being (β = -0.004, P = 0.221).

CONCLUSIONS

Taken together, the results suggest that different dimensions of the filial behaviour of the oldest son exert differential effects on emotional regulation and subjective well-being in older parents. Based on the current findings, there is a need to develop adaptive emotional regulatory capacity intervention programs for the development and enhancement of subjective well-being in older parents within their familial context.

Widowhood and Depression in a Cross-National Perspective: Evidence from the United States, Europe, Korea, and China

Objectives

We explore marital and depression trajectories over time for men and women, and distinguish between mood and somatic depression across contexts.

Method

We use longitudinal data from 2002 to 2013 from the United States, England, Europe, Korea, and China to explore depression among individuals married at baseline and follow their trajectories into widowhood with married as the reference group. We use random effects models to estimate these trajectories using the Center for Epidemiologic Studies Depression Scale (CES-D) or EURO-D scales for men and women.

Results

Depression peaks within the first year of widowhood for men and women, but women recover to levels comparable to married counterparts in all countries. Men sustain high levels of depression even 6-10 years post-widowhood everywhere except Europe. Widowed women have higher somatic depression compared to men, who have higher mood depression. Family plays differential roles in mediating depression across countries.

Discussion

Our research shows the complex global relationship between widowhood and depression. Studies that do not compare depression trajectories over time may make incorrect inferences about the persistence of depression by gender and country. Interventions should target different components of depression: mood-related symptoms for men and somatic-related symptoms for women for most effective recovery.

Social Integration and Terminal Decline in Life Satisfaction Among Older Japanese

Objectives

Well-being typically exhibits pronounced deteriorations with approaching death, with sizeable interindividual variations in levels and changes. It is less well understood how psychosocial factors contribute to these individual differences. We examined whether and how social integration is associated with terminal trajectories of well-being, indexed as life satisfaction.

Method

Data were drawn from 1,119 deceased Japanese participants of a 15-year longitudinal study (age at death: M = 79.2 years; SD = 7.7 years; 43.1% women). Life satisfaction, structural and functional features of social integration (e.g., frequency of contact with family and nonfamily, and perceived overall support, respectively), sociodemographic characteristics, and physical function were assessed.

Results

Social integration predicted individual differences in terminal decline in life satisfaction, after controlling for age at death, gender, education, and physical function: More diverse social relationships were associated with higher levels of life satisfaction at 1 year before death. In addition, individuals who exhibited more decline in social participation and perceived less support showed more pronounced decline with increasing proximity of death.

Discussion

This study suggests that social integration plays a protective role in late-life well-being and that sustaining an active social life and supportive social interactions may help mitigate terminal decline in well-being.

Subjective well-being in centenarians: a comparison of Japan and the United States

OBJECTIVE

The present study examined the cultural differences and similarities in the levels and predictors of subjective well-being in Japanese and American centenarians.

METHOD

We analyzed data on cognitively intact Japanese (N = 59) and American (N = 125) participants from the Tokyo and Georgia Centenarian Studies, respectively. The Philadelphia Geriatric Center Morale Scale was used to measure subjective well-being, while sociodemographic, social, and health resources were assessed as potential predictors.

RESULTS

The American participants reported higher scores on well-being (satisfaction with social relations and psychological comfort). However, cultural differences in the levels of well-being disappeared after we controlled for its predictors. The regression models revealed that health resources (cognitive function, hearing problems, and activities of daily living) were strong predictors of well-being in both countries. Social resources (living with others) were strongly associated with one dimension of well-being (attitude toward one's aging) among the Japanese participants.

DISCUSSION

The findings support the existing lifespan and cross-cultural literature, indicating that declines in health impose certain limitations on adaptive capacity in oldest-old age irrespective of cultures, and that social embeddedness is valued in Eastern cultures. The authors speculate that cultural values, i.e. personal autonomy versus relational harmony, play an important role for well-being in oldest-old age.

Valuation of Life Among Old and Very Old Adults: Comparison Between Germany and Japan

Background and Objectives

Valuation of life (VOL) represents a construct capturing individuals’ active attachment to their life. The majority of studies on VOL were conducted in North America and Europe where personal autonomy and independence are highly valued, leaving open the question about the relevance of this construct in interdependence-oriented cultures. Using a framework of cross-cultural and life-span theories, the present study compared levels and predictors of VOL between the young-old and old-old individuals from Germany and Japan.

Research Design and Methods

Two hundred fifty-seven Germans and 248 Japanese, matched by age, gender, education, and IADL, answered a 5-item VOL scale and shared information on sociodemographic, social, and health resources.

Results

Germans’ VOL levels were higher than in Japanese participants. Both culture- and age-moderated predictions of VOL: education was significant only in the young-old Japanese, and close social partners mattered in the old-old, not in the young-old. Health determined VOL irrespective of culture and age.

Discussion and Implications

The findings suggest that cultural values and aging processes should be considered to better understand how individuals value their life and to help older adults to feel that his/her life is meaningful and worth living.

The impacts of community social capital on the life satisfaction of older adults in Hong Kong: the moderator role of intergenerational family capital

OBJECTIVE

This study examined the moderator role of intergenerational family capital on the relationship between community social capital and life satisfaction of older Chinese adults.

METHOD

The data were derived from a quota sampling of 372 older adults aged 60 and above, who were interviewed at four districts in Hong Kong in 2011. Multiple group analysis was employed to examine the proposed model.

RESULTS

For the low family capital group, community social capital was found to be a significant predictor of life satisfaction, even when the well-known covariates were controlled. However, the association between community social capital and life satisfaction was statistically non-significant among the high family capital group.

DISCUSSION

The findings highlighted the interplay between community social capital and intergenerational family capital, which supported community social capital replacement theory in understanding the mechanism linking social capital to life satisfaction in older age in a Chinese context. Community social capital can play a compensatory role in maintaining the mental health of older people. It is particularly important for older adults who lack family support and/or suffer from social isolation and loneliness in local communities.

Ambient air pollution and suicide in Tokyo, 2001-2011

BACKGROUND

Some evidence suggests an association may exist between the level of air pollution and suicide mortality. However, this relation has been little studied to date. The current study examined the association in Tokyo, Japan.

METHODS

Suicide mortality data for Tokyo for the 11-year period 2001-2011 were obtained together with data on four air pollutants: fine particulate matter (PM2.5), suspended particulate matter (SPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2). A time-stratified case-crossover study design was used to examine the daily association between the level of air pollution and suicide mortality.

RESULTS

During the study period there were 29,939 suicide deaths. In stratified analyses an interquartile range (IQR) increase in the same-day concentration of NO2 was linked to increased suicide mortality among those aged under 30 (percentage change: 6.73%, 95% CI: 0.69-13.12%). An IQR increase in PM2.5 and SO2 was associated with a 10.55% (95% CI: 2.05-19.75%) and 11.47% (95% CI: 3.60-19.93%) increase, respectively, in suicide mortality among widowed individuals for mean exposure on the first four days (average lags 0-3). Positive associations were observed for the air pollutants in the summer although associations were reversed in autumn.

LIMITATIONS

We relied on monitoring data to approximate individual exposure to air pollutants.

CONCLUSIONS

Higher levels of air pollution are associated with increased suicide mortality in some population subgroups in Tokyo. Further research is needed to elucidate the mechanisms linking air pollutants and suicide in this setting.

Is giving or receiving psychologically beneficial to older mothers in South Korea? Importance of marital status

In order to understand intergenerational financial transfers and subjective well-being for older mothers, this study argues that marital status is an important factor to be considered. Using the first wave of the Korean Longitudinal Study of Aging (KLoSA), this study finds that married older mothers report higher levels of life satisfaction when they provide economic support but widowed older mothers feel higher levels of life satisfaction when they receive economic support. Also, regular or irregular financial support appears to also matter in the associations between financial support and life satisfaction. These findings suggest that married and widowed older mothers have different viewpoints about the parent-children relationship.

Older parents enjoy better filial piety and care from daughters than sons in China

This study analyzes the unique datasets of the Chinese Longitudinal Healthy Longevity Survey using logistic regression and controlling for various covariates. Our analyses clearly demonstrate that disabled older parents are more satisfied with care provided by daughters than sons and that older parents enjoy greater filial piety from and better relationships with daughters than sons. The daughter-advantages of enjoying greater filial piety from and better relationships with children are stronger among the oldest-old aged 80+ than the young-old aged 65-79, and surprisingly more profound in rural areas than urban areas, while son-preference is much more prevalent among rural residents. We also discuss why China's rigorous fertility policy until October-2015 and much less-developed pension system in rural areas substantially contribute to sustaining traditional son-preference and a high sex ratio at birth (SRB) when fertility is low. We recommend China take integrative public health policy actions of informing the public that having daughter(s) is beneficial for old age care, developing the rural pension system and implementing the universal two-child policy as soon as possible. We believe that these policy actions would help to reduce son-preference, bring down the high SRB, and enable more future elderly parents to enjoy better care from their children and healthier lives.

Family support, anticipated support, negative interaction, and psychological well-being of older parents in Thailand

BACKGROUND

A number of studies have consistently indicated that family support has a powerful impact on older parents' well-being, but little is known about the effects of anticipated support and negative interaction on psychological well-being. The present study attempted to examine the relationships between family support, negative interaction, and psychological well-being in older Thai parents.

METHODS

The sample included 578 elderly parents aged 60 years and older. Multiple regression models were employed to determine whether received support, anticipated support, and negative interaction influence older parents' well-being.

RESULTS

Findings revealed that greater emotional and instrumental support received from family members and anticipated support were significantly associated with a greater sense of older parents' psychological well-being. However, psychological well-being was lower for those with more negative family interactions.

CONCLUSION

The results suggest that filial piety and family solidarity should be considered when developing elder care policy and interventions to promote psychological well-being.

Depressive Symptoms, Transitions to Widowhood, and Informal Support From Adult Children Among Older Women and Men in Japan

This study examines the relationships among depressive symptoms, transitions to widowhood, worsening health, and family support in Japan over 10 years. The analyses focus on availability and receipt as the two primary dimensions of intergenerational support relationships. We used growth curve models to analyze data from the Nihon University Japanese Longitudinal Study of Aging, finding that (1) becoming widowed correlated with increased depressive symptoms and this relationship was weaker among women than men, (2) continuous widowhood was associated with fewer depressive symptoms over time, (3) transitions to coresidence with sons and daughters among the widowed was correlated with reduced depressive symptoms, (4) self-reported health and difficulty with activities of daily living were predictors of depressive symptoms over time. The findings suggest the importance of new research on household transitions, availability and proximity of family caregivers, and social embeddedness as protections against depressive symptoms.

Active Social Participation and Mortality Risk Among Older People in Japan

A large literature suggests that active social participation contributes to the well-being of older people. Japan provides a compelling context to test this hypothesis due to its rapidly growing elderly population and the phenomenal health of the population. Using the Nihon University Japanese Longitudinal Study of Aging, this study examines how social participation, measured by group membership, is related to the risk of overall mortality among Japanese elders aged 65 and older. Results from Cox proportional hazards models show that group affiliation confers advantages against mortality risk, even after controlling for sociodemographic characteristics, physical health measures, and family relationship variables. In particular, activities geared more toward self-development, such as postretirement employment and lifelong learning, are strongly associated with lower levels of mortality. Findings suggest that continued social participation at advanced ages produces positive health consequences, highlighting the importance of active aging in achieving successful aging in the Japanese context.
