The aim of this study is to investigate how well-being trajectories evolve after the onset of functional disability, comparing affective, cognitive, and eudemonic dimensions, while also assessing how they are influenced by temporary functional disability, distinguishing between persistent and transient cases. Methods We reordered longitudinal panel data from waves 4 to 8 of the Survey of Health, Ageing and Retirement in Europe (SHARE), from more than 3,500 Europeans to align on the transition from no limitation to at least one limitation in activities of daily living. We used linear spline growth models separately for each of the three well-being measures used (EURO-D, CASP, life satisfaction) to examine trajectories. Results We observed a substantial decline in all three well-being measures at functional disability onset, with life satisfaction less affected (standardised mean differences = -0.11) than quality of life (-0.23) and depression (-0.27). Short-term disability on average led to a return to the initial well-being level within, while long-term disability led to a pronounced decline during the transition, with much less adaptation. Discussion Our findings highlight the significant impact that functional disability can have on well-being, revealing distinct patterns across various dimensions. Persistent disability often marks a crucial stage in the well-being of older people, whereas transient cases are characterised by a subsequent return to previous levels of well-being.","PeriodicalId":501650,"journal":{"name":"The Journals of Gerontology: Series B","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Emerging evidence indicates that broad-based contextual factors such as the COVID-19 pandemic – and the use of the internet throughout – are differentially associated with the experience of loneliness. We therefore target internet usage and loneliness among middle-aged and older adults during the pandemic and examine the moderating role of age, gender, and limiting illness therein. Methods We applied hierarchical regression models to data from the COVID-19 sub-study Wave 1 (June/July 2020) of the English Longitudinal Study of Ageing (N= 4,790; Mage= 70.2; SD= 9.0; range: 50-90; 43.5% male). Results Infrequent internet use was associated with less loneliness compared to very frequent users – an association that strengthened with age. Conversely, purpose of internet use was associated with more loneliness, with higher levels exhibited by those searching for health-related information – an effect stronger among those with a limiting illness.

Consistent with this, previous research has shown that adult children’s problems are associated with worse parental well-being. Because multigenerational ties have become increasingly important in the 21st century, we propose that adult grandchildren’s problems may also impact grandparents’ well-being. In this paper, we test this hypothesis and investigate the moderating effects of grandparents’ race and maternal/paternal status. Methods The analytic sample includes 206 grandparents aged 65-95 who participated in the second wave of the Family Exchanges Study. Adult grandchildren’s problems were operationalized as the proportions of adult grandchildren who experienced (1) physical-emotional problems and (2) lifestyle-behavioral problems. Results Main effects multilevel analyses suggested that adult grandchildren’s problems did not predict grandparents’ well-being. However, moderation analyses revealed that the association between grandparents’ depressive symptoms and adult grandchildren’s physical-emotional problems was larger among Black than White grandparents, and maternal than paternal grandparents. Adult grandchildren’s lifestyle-behavioral problems did not predict grandparents’ depression, and these effects were not conditioned by race or maternal/paternal status.

Methods Data were collected as part of the second (M2, 2004-05) and third (M3, 2013-14) waves of the Midlife in the United States Study (MIDUS). The analysis sample included 2,532 participants with all variables at M2 and M3. Participants’ ages ranged from 33 to 83 (M=54.92, SD=11.13) at M2. Results There was a reciprocal relationship between cognitive control beliefs and executive functioning. Higher executive functioning was related to greater maintenance of cognitive control beliefs for older, not younger, adults. Higher cognitive control beliefs were related to less decline in executive functioning. Though cognitive control beliefs predicted 10-year changes in episodic memory, the inverse relationship was not supported. Frequency of engaging in stimulating cognitive activities mediated the relationship between executive functioning and 10-year changes in cognitive control beliefs, but not cognitive control beliefs and 10-year changes in cognition. Conclusions Cognitive control beliefs are a promising mechanism to help protect against age-related declines in both executive functioning and episodic memory. Moreover, executive functioning also impacts cognitive control beliefs. Specifically, those with higher executive functioning engage more frequently in stimulating cognitive activities, which helps maintain higher cognitive control beliefs.","PeriodicalId":501650,"journal":{"name":"The Journals of Gerontology: Series B","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates and compares the functional transitions among older adults living in rural areas who receive care from daughters’ and from sons’ families. Method This study utilizes the ‘Well-being of Elderly Survey in Anhui Province’ (WESAP), from 2001 to 2021. Our sample included 2,797 individuals aged 60 years or over. Functional status was based on the activities of daily living (ADLs) and the instrumental activities of daily living (IADLs). We employed a random-effects ordered logit model to examine the functional transitions among the older adults. Results Receiving care from daughters’ families is significantly associated with a lower likelihood of functional decline compared to receiving care from sons’ families in rural China. The advantage associated with daughter care becomes more pronounced among older individuals with a severe functional difficulty compared to those with a mild or moderate functional difficulty. The difference is prevalent among older adults aged 75 and above, with less wealth or multiple chronic diseases, or who live alone. Furthermore, among those with severe functional difficulties, the daughter advantage is more significant for fathers as compared to mothers. Discussion Nowadays, daughters’ families can provide high-quality informal care, often surpassing that offered by sons’ families. This daughter advantage becomes even more significant among older adults who have a higher need for family care, such as those with severe disabilities and limited financial resources.","PeriodicalId":501650,"journal":{"name":"The Journals of Gerontology: Series B","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141880489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Using data from the Health and Retirement Study and the National Health Interview Study Linked Mortality Files, we define a measure of dual functionality based on the absence of limitations in activities of daily living and dementia. We estimate age-graded dual-function rates among adults 65+ and age-65 dual-function life expectancy across levels of education stratified by gender. Results In their mid 60s, 67 percent of women with less than a high school degree manifest dual functionality as compared with over 90 percent of women with at least a four-year college degree. A similar pattern holds among men. These education-based gaps in dual functionality remain across later life, even as dual-function rates decline at older ages. Lower dual-function rates among older adults with less education translate into inequalities of 6.7 and 7.3 years in age-65 dual-function life expectancy between men and women respectively with at least a four-year college degree compared to their counterparts with less than a high school degree. Discussion Older adults, particularly women, with less than a high school degree are estimated to live a smaller percentage of their remaining years with dual functionality compared with older adults with at least a college degree.
