Abstract
Understanding non-pathological cognitive aging processes remains a public health goal and research priority. Age-associated cognitive aging is a normal human process, however, individual differences may aid in the mitigation of cognitive aging. Assessing the role of certain protective factors (i.e., age, marital status, and gender) that influence age-related cognitive aging is imperative to slow down the progression of unwarranted cognitive aging. Participants aged over 18 (N = 123; 97 females and 26 males) recruited from Sydney, New South Wales, and Gold Coast, Queensland, completed an online neuropsychological test battery with computer-administered tasks, assessing impulsivity and working memory, which were entered as dependent variables. A 3(Age Group: 18-27 years; 28-61 years; 62+ years) x2(Marital Status: married; single) x2(Gender: male; female) Multivariate Analysis of Covariance (MANCOVA) design was used to examine the relationship between age, marital status, and gender (entered as independent variables) on cognitive aging. Participants' total scores from psychometrically sound measures assessing depressive symptomology, personal wellbeing, resilience, and social network engagement, were entered as covariates. No significant effects were found from the independent variables included in the MANCOVA. A significant covariate effect for resilience and depressive symptomology on impulsivity was found. A multiple regression analysis was performed on the significant covariates, and revealed increased resilience and depressive symptomology to significantly predict greater impulsivity.

Cecchini V, Agahi N. Does losing family members in midlife matter for late-life mental and cognitive health? A longitudinal study of older Swedes spanning 30 years. Aging Ment Health 2024:1-9. [PMID: 38644675 DOI: 10.1080/13607863.2024.2341877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Accepted: 04/05/2024] [Indexed: 04/23/2024]
Abstract
OBJECTIVES Mental and cognitive health is crucial to ensure well-being in older age. However, prolonged periods of stress, grief, and bereavement might compromise mental health balance, leading to profound changes. This study investigated the sex-stratified associations between midlife bereavement experiences (e.g. sibling loss, spousal loss, and multiple losses) and late-life depression (LLD) and cognitive impairment. METHOD Linked data from the Swedish Level-of-Living Survey and the Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD) were used. Multiple logistic regressions were performed to examine the associations between midlife bereavement and LLD (n = 1078) and cognitive impairment (n = 995), separately. RESULTS Sibling loss and multiple losses in midlife were associated with lower odds of LLD, especially among women. Among men, sibling loss in midlife was associated with lower odds of cognitive impairment, while the experience of two losses among women suggested an increased (but non-significant) risk of cognitive impairment. Interaction analyses did not show significant effects between bereavement and gender on LLD and cognitive impairment. CONCLUSION Midlife bereavement might have gendered implications on LLD and cognitive impairment, but associations need to be confirmed by well-powered studies. Further research is warranted to elucidate the association between multiple midlife losses and reduced LLD risk.

Abstract
Spousal bereavement is associated with health declines and increased mortality risk, but its specific impact on physical and cognitive capabilities is less studied. A historical cohort study design was applied including married Tromsø study participants (N=5739) aged 50-70 years with baseline self-reported overall health and health-related factors and measured capability (grip strength, finger tapping, digit symbol coding, and short-term recall) at follow-up. Participants had data from Tromsø4 (1994-1995) and Tromsø5 (2001), or Tromsø6 (2007-2008) and Tromsø7 (2015-2016). Propensity score matching, adjusted for baseline confounders (and baseline capability in a subset), was used to investigate whether spousal bereavement was associated with poorer subsequent capability. Spousal bereavement occurred for 6.2% on average 3.7 years (SD 2.0) before the capability assessment. There were no significant bereavement effects on subsequent grip strength, immediate recall, or finger-tapping speed. Without adjustment for baseline digit symbol coding test performance, there was a negative significant effect on the digit symbol coding test (ATT -1.33; 95% confidence interval -2.57, -0.10), but when baseline digit symbol coding test performance was taken into account in a smaller subsample, using the same set of matching confounders, there was no longer any association (in the subsample ATT changed from -1.29 (95% CI -3.38, 0.80) to -0.04 (95% CI -1.83, 1.75). The results in our study suggest that spousal bereavement does not have long-term effects on the intrinsic capacity components physical or cognition capability to a notable degree.

Abstract
Objectives: Although there is growing evidence on widowhood and cognitive function, existing studies have shown mixed results. Little is known about protective factors that may contribute to resilience, thereby ameliorate the adverse effect of widowhood on cognition among older Asian immigrants. This study explored potential moderators (i.e. social support, acculturation, leisure activities) in the association between widowhood and cognitive function among older Chinese immigrants.Method: The study sample included 2,515 adults aged 60 or older who completed two waves (2011-2013 and 2013-2015) of the Population Study of Chinese Elderly in Chicago. Cognitive function was indexed by global cognitive function and episodic memory. Linear regression analyses were conducted with interaction terms.Results: Our results show that social support moderated the relationship between widowhood and global cognitive function, and acculturation moderated the relationship between widowhood and episodic memory. The adverse effect of widowhood on cognitive function was more pronounced at lower levels of social support and acculturation.Conclusion: Our findings indicate buffering roles of social support and acculturation in cognitive health among older Chinese immigrants who experience widowhood. Providing supportive programs and interventions to increase social support and acculturation is suggested to promote cognitive function in this population.

Abstract
OBJECTIVES This study investigates the cognitive function trajectories associated with prolonged social isolation, while distinguishing between a lack of informal social contact and a lack of formal social activity as the source of social isolation. METHODS Data from the Korean Longitudinal Study of Ageing spanning 12 years between 2006 and 2018 were analyzed. A lack of frequent informal social contact or formal social activity was used to assess social isolation, and cognitive function was measured by Korean Mini-Mental State Examination. Fixed effects regression models were used to account for unobserved individual-level confounders. RESULTS A prolonged absence of frequent informal social contact was linked to a decline in cognitive function up to the three waves of exposure (b = -2.135), but cognitive function has not declined further since then. A persistent lack of formal social activity was associated with a decline in cognitive function up to the fifth and subsequent waves of exposure (b = -3.073). No gender differences were observed in these relationships. CONCLUSION Prolonged social isolation, particularly a lack of formal social activity, can pose a significant threat to the cognitive health of older adults.

Abstract
Objectives: Research suggests that the death of a spouse has an adverse effect on a widow(er)'s cognition. However, little research has examined how the marital context before widowhood and gender influence this association. Guided by the social ambivalence and disease (SAD) model, this study examined the associations between spousal loss and cognition , with moderating effects of gender and pre-loss marital quality.Method: We analyzed a national longitudinal data, Midlife in the United States (MIDUS), specifically MIDUS 2 (2004-2005) and MIDUS 3 (2013-2014). The analytic sample consisted of (1) 146 participants who experienced the death of their spouse between MIDUS 2 and MIDUS 3 and (2) 144 age- and gender-matched comparison participants who did not lose their spouse during the period.Results: Adverse influence of widowhood on cognition was more pronounced among bereaved men than bereaved women. Widowed individuals whose relationships with their deceased spouse were ambivalent had poorer cognition than widowed individuals who had aversive relationships with their deceased spouse.Conclusion: Findings suggest that the influence of spousal death on cognitive functioning depends on gender and pre-loss marital quality, emphasizing the importance of considering pre-loss marital relationship and gender dynamics in developing efficient interventions for the widowed.

Abstract
OBJECTIVE The need to promote awareness of dementia prevention is broadly emphasized in Israel. Currently, there is no valid version of a Hebrew questionnaire to assess attitudes and beliefs related to dementia prevention. This study aimed to translate and validate the MCLHB-DRR questionnaire among the general Israeli population. METHODS A total sample of 328 participants between the ages of 50-83 years (mean = 58.7, SD = 6.9) were included in this study. Participants completed the online translated MCLHB-DRR questionnaire. Exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) were conducted to assess the questionnaire's validity. Internal consistency was assessed using Cronbach's alpha. RESULTS The EFA analysis revealed a seven-factor model with 27 items. One item related to perceived barriers and two items related to perceived severity were deleted. The CFA analysis confirmed a good model fit with the deleted items (χ2/df = 2.146, CFI = 0.930, TLI = 0.916, RMSEA = 0.049). Cronbach's alpha values ranged from 0.61 to 0.92. CONCLUSIONS The Hebrew MCLHB-DRR questionnaire is a valid and reliable measurement tool for assessing attitudes and beliefs related to health behaviours and lifestyle changes for dementia risk reduction in Israeli adults over the age of 50.

Abstract
(1) Background: Research indicates that most elderly widows are at a high risk of experiencing negative psychological symptoms. It is common for elderly women in rural and remote areas to live alone without family support to cope with stress due to the mass rural-to-urban migration of China’s youth labor force. Such a situation further worsens their psychological health and well-being. However, the prevalence of and risk factors associated with negative psychological symptoms (loneliness, depression, and anxiety) among remote elderly widows living alone in China are currently unclear; (2) Methods: A cross-sectional study was conducted in Hunan Province, China. The loneliness was assessed through the University of California at Los Angeles Loneliness Scale (ULS-8). The depression and anxiety were assessed with the Short Form Geriatric Depression Scale (GDS-15) and Generalized Anxiety Disorder Scale (GAD-7), respectively. The Chi-square test and correlation analysis were conducted to identify factors associated with negative psychological symptoms. Logistic regression was performed to predict risk and protective factors contributing to loneliness, depression, and anxiety symptoms. The significance level was set as p < 0.05; (3) Results: A total of 271 remote elderly widows living alone were enrolled in the present study. Additionally, 234 valid questionnaires were returned (valid response rate = 86.3%). The prevalence of loneliness, depression and anxiety was 8.1%, 44.0%, and 16.7%, respectively. Acute or chronic medical conditions, marital happiness, being the primary caregiver before widowhood and anticipating the death of the spouse differed significantly in the distribution of negative psychological symptoms. Logistic regression analysis predicted that participants who were satisfied with their marriage had a lower likelihood to experience loneliness, depression, and anxiety (p < 0.05). Being the spouse’s primary caregiver before widowhood was more likely to have symptoms of loneliness (p < 0.01). Those with various acute or chronic medical conditions were more likely to suffer from depression (p < 0.01); (4) Conclusions: Remote elderly widows living alone in China are prone to loneliness, depression, and anxiety symptoms. Being the primary caregiver before widowhood and having many acute or chronic medical conditions are risk factors for loneliness and depression, respectively. Marital happiness is the protective factor against negative psychological symptoms. To accomplish the goal of equitable access to mental health care in China, evidence-based policy and resource development to support psycho-social interventions that prevent and manage negative psychological symptoms for remote elderly widows living alone are urgently needed.

Abstract
PURPOSE Previous studies have linked levels of perceived chronic stress to older adults' cognitive functioning, but few have focused on the impact of chronic stressor types. Thus, this study aimed to (1) identify patterns of chronic stressor types and (2) examine the effects of these patterns on cognitive functioning trajectories among older adults. METHODS Two longitudinal studies were conducted separately to test the study aims and ensure replicability across samples and time points. Both used three timepoints (Study 1: 2006, 2008, and 2010, n = 6974; Study 2: 2012, 2014, and 2016, n = 6604) collected from older Americans in the Health and Retirement Study. Participants did not overlap between the two studies. Latent class analyses were conducted to identify chronic stressor-type patterns. Latent growth curve models were used to test the effects of chronic stressor-type patterns on cognitive functioning trajectories. RESULTS Three latent classes of stressor types were identified in both studies: egocentric (4.56%; 5.85%), nonegocentric (8.58%; 10.03%), and low stressor (86.86%; 84.12%). In both studies, compared to the low stressor class, the egocentric stressor class had significantly lower initial cognitive scores (B = -0.72, ρ < 0.001; B = -0.46, ρ < 0.05), while the nonegocentric stressor class did not have significantly different initial scores, with covariates controlled. Additionally, in Study 1, the nonegocentric stressor class had significantly slower cognitive decline rates than the low stressor class (B = 0.11, ρ < 0.05). CONCLUSIONS Findings suggested that nonegocentric stressors are an important stressor source in late adulthood but are less detrimental to cognitive functioning than egocentric stressors. Health management interventions may reduce older adults' cognitive health disparities caused by self-health and financial stressors. More support, including financial subsidies, caregiver stress management training, or support groups, should be provided to older caregivers, especially those with few resources.

Abstract
AIM Spouse bereavement is one of life's greatest stresses and has been suggested to trigger or accelerate cognitive decline and dementia. However, little information is available about the potential brain pathologies underlying the association between spouse bereavement and cognitive decline. We aimed to investigate that lifetime spouse bereavement is associated with in vivo human brain pathologies underlying cognitive decline. METHODS A total of 319 ever-married older adults between the ages of 61 and 90 years underwent comprehensive clinical assessments and multimodal brain imaging including [11 C] Pittsburgh compound B-positron emission tomography (PET), AV-1451 PET, [18 F] fluorodeoxyglucose-PET, and magnetic resonance imaging. Participants were classified as experiencing no spouse bereavement or spouse bereavement, and comparisons using propensity score matching (59 cases and 59 controls) were performed. RESULTS Spouse bereavement was significantly associated with higher cerebral white matter hyperintensity (WMH) volume compared with no spouse bereavement. Interaction and subsequent subgroup analyses showed that spouse bereavement was significantly associated with higher WMH in the older (>75 years) subgroup and among those with no- or low-skill occupations. In addition, spouse bereavement at 60 years or older affects WMH volume compared with no spouse bereavement, whereas spouse bereavement at younger than 60 years did not. No group differences were observed in other brain pathologies between spouse bereavement categories. CONCLUSIONS The findings suggest that the spouse bereavement may contribute to dementia or cognitive decline by increasing cerebrovascular injury, particularly in older individuals and those with no- or low-skill occupations.

Abstract
Background Widowhood, a marital status that disproportionately affects older women, has been associated with poorer health compared to married individuals. However, relatively little is known about the association between widowhood in later-life and cognitive health in low- and middle-income countries. Methods To address this research gap, we used data from the Longitudinal Aging Study in India (2017-19) to investigate the widowhood disparity in cognitive health among mid-aged and older women in India, including how this relationship varies by the duration of widowhood. We further examined the extent to which economic, social, and health conditions mediate this association. Results Cognition scores for widowed women were on average lower by almost 0.1 standard deviations compared to married women. Overall, this disparity increased with widowhood duration, with non-linearities in this association. The disparity in cognition scores increased with widowhood duration up to twenty years but did not increase further among those with longer widowhood duration. Worse physical and mental health were found to mediate almost thirty percent of the total association between widowhood and cognition. These mediators were most useful in explaining the association between lower cognition and widowhood among women who experienced widowhood for ten years or longer. Conclusion The study highlights the significant disadvantage in cognitive functioning among older widowed women in India. The study also provides evidence on potential mediators, suggesting differential effects of mediators at different stages of widowhood.

Lee JJ, Kim JH, Song DS, Lee K. Effect of Short- to Long-Term Exposure to Ambient Particulate Matter on Cognitive Function in a Cohort of Middle-Aged and Older Adults: KoGES. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:9913. [PMID: 36011565 PMCID: PMC9408640 DOI: 10.3390/ijerph19169913] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 08/05/2022] [Accepted: 08/09/2022] [Indexed: 06/15/2023]
Abstract
Exposure to ambient air pollution and its threat to human health is a global concern, especially in the elderly population. Therefore, more in-depth studies are required to understand the extent of the harmful effects of particulate matter (PM) based on duration and levels of exposure. An investigation was conducted to determine the association between short- (1-14 days), medium- (1, 3, and 6 months), and long-term (1, 2, and 3 years) exposure to air pollutants (PM2.5 and PM10) and cognitive function among Koreans (4175 participants, mean age 67.8 years, 55.2% women) aged over 50 years. Higher levels of PM2.5 exposure for short to long term and PM10 exposure for medium to long term were found to be associated with decreased cognitive function, as indicated by lower scores of the Mini-Mental State Examination adopted in Korean (K-MMSE). There were significant effect modifications by sex, age group, alcohol consumption, physical activity, and smoking status in the association between long-term PM2.5 and PM10 exposure and cognitive function. These findings, which underscore the importance of the efforts to reduce the exposure levels and durations of air pollutants, especially in the vulnerable elderly population, provide evidence for establishing more stringent policies for air pollution regulations.

Abstract
Purpose: To explore the experience of negative affect amongst older adults residing in long-term care facilities (LTCFs).Methods: A total of 38 participants aged 65 years or above from seven LTCFs in the Henan Province were interviewed in an unstructured manner by using the phenomenological research method. Data were analyzed by the Colaizzi method with NVivo11.0 software.Results: Three main themes emerged: (a) loneliness (lack of family affection, no common topic, and few entertainment activities), (b) chronic anxiety (suffering from disease, fear of death, and interpersonal tension), (c) subthreshold depression (diminished self-care ability, high economic pressure, and spousal bereavement).Conclusions: Older adults residing in LTCFs experienced the negative affect of loneliness, chronic anxiety, and subthreshold depression. By identifying the specific psychological issues of older adults, tailored practical initiatives need to be developed in order to reduce negative affect, improve psychological resilience, and enhance subjective well-being of older adults.

Association of marital status with cognitive function in Chinese hypertensive patients: a cross-sectional study. BMC Psychiatry 2022; 22:504. [PMID: 35897015 PMCID: PMC9327272 DOI: 10.1186/s12888-022-04159-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Accepted: 07/18/2022] [Indexed: 11/10/2022] Open
Abstract
PURPOSE The aim of this study was to evaluate the association of marital status with cognitive function and to examine the potential effect modifiers in Chinese hypertensive populations. METHODS A total of 9,525 adult Chinese hypertensive patients were enrolled in this cross-sectional study. Cognitive function, as the dependent variable in our study, was assessed by the Chinese version of the Mini-Mental State Examination (MMSE). We adjusted for potential confounding factors in multiple linear regression models to examine the relationship of marital status with cognitive function. In addition, we divided the population according to sex to explore whether there were sex-specific differences. RESULTS Among the 9,525 study participants, the mean (SD) age for men was 63.5 (10.3) years, and the mean MMSE score was 24.9 ± 5.0, whereas for women, the mean (SD) age was 63.8 (9.3) years, and the mean MMSE score was 19.4 ± 6.4. Unmarried persons had lower scores on the MMSE and lower subscores in each of the cognitive domains. A stronger correlation between marital status and a lower MMSE score was statistically significant in men (unmarried men: β = -1.55; 95% CI: -1.89, -1.21) but not women (unmarried women: β = -0.22; 95% CI: -0.56, 0.12; p interaction = 0.006). Compared to men who were widowed or divorced, never married men were more likely to have lower MMSE scores (β = -2.30, 95% CI -3.10,-1.50; p < 0.001). CONCLUSIONS Our study demonstrated that being unmarried is an extremely important but neglected social risk factor for cognitive function. Sex was a strong effect modifier: being unmarried was correlated with a higher risk of cognitive decline than being married in Chinese hypertensive men, especially among older men, but this correlation was not observed among women. Moreover, never married men showed poorer cognitive function than those who were divorced or widowed.

The Role of Purpose in Life in the Relationship Between Widowhood and Cognitive Decline Among Older Adults in the U.S. Am J Geriatr Psychiatry 2022; 30:383-391. [PMID: 34417084 DOI: 10.1016/j.jagp.2021.07.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 07/18/2021] [Accepted: 07/18/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVES The objective of this study was to examine the role of purpose in life in the relationship between widowhood and cognitive decline. METHODS This study used a sample of 12,856 respondents (20,408 observations) collected from a national panel survey, the 2006-2014 waves of the Health and Retirement Study (HRS), that sampled older adults aged 50 or older. The study estimated growth-curve models with years since spousal death, purpose in life, and interaction between the two to predict cognition using three measures-total cognition, fluid, and crystallized intelligence scores. We also estimated growth-curve models by sex, race/ethnicity, and education. RESULTS While years since spousal death negatively correlated with cognition, purpose in life positively correlated with cognition. Furthermore, purpose in life had a moderating effect on the relationship between years since spousal death and cognition. This effect was found by using total cognition (coef. = 0.0515; z = 2.64; p < 0.01) and fluid intelligence scores (coef. = 0.0576; z = 3.23; p < 0.05). The same effects were salient among females (coef. = 0.0556; z = 2.19; p < 0.05), Whites (coef. = 0.0526; z = 2.52; p < 0.05), and older adults with more education (coef. = 0.0635; z = 2.10; p < 0.05). CONCLUSION Higher purpose in life relates to the negative correlations between widowhood and cognition of older adults. Educational programs improving purpose in life are a possible avenue for reducing the adverse effect of widowhood on cognition and warrant future exploration.

Spousal caregiving, widowhood, and cognition: A systematic review and a biopsychosocial framework for understanding the relationship between interpersonal losses and dementia risk in older adulthood. Neurosci Biobehav Rev 2022; 134:104487. [PMID: 34971701 PMCID: PMC8925984 DOI: 10.1016/j.neubiorev.2021.12.010] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 11/23/2021] [Accepted: 12/06/2021] [Indexed: 01/18/2023]
Abstract
Accumulating research suggests that stressful life events, especially those that threaten close intimate bonds, are associated with an increased risk of dementia. Grieving the loss of a spouse, whether in the form of caregiving or after the death, ranks among 'life's most significant stressors', evoking intense psychological and physiological distress. Despite numerous studies reporting elevated dementia risk or poorer cognition among spousal caregivers and widow(er)s compared to controls, no review has summarized findings across cognitive outcomes (i.e., dementia incidence, cognitive impairment rates, cognitive performance) or proposed a theoretical model for understanding the links between partner loss and abnormal cognitive decline. The current systematic review summarizes findings across 64 empirical studies. Overall, both cross-sectional and longitudinal studies revealed an adverse association between partner loss and cognitive outcomes. In turn, we propose a biopsychosocial model of cognitive decline that explains how caregiving and bereavement may position some to develop cognitive impairment or Alzheimer's disease and related dementias. More longitudinal studies that focus on the biopsychosocial context of caregivers and widow(er)s are needed.

Abstract
The loss of a spouse is a common and natural life event for older adults. Nearly one of four older bereaved spouses experience prolonged grief, impaired function or chronic depression. Mechanisms underlying these and other long-term health risks are not well understood. We conducted a scoping literature review to examine the interventions and outcomes that have been studied for late-life spousal bereavement to date. We identified 22 studies of group and individual-level interventions with most studies concerning grief processes within the first year. Nearly all studies evaluated emotional and psychological symptoms of loss and a small number evaluated the restoration of adaptive functioning. Four interventions addressed the treatment of complicated grief or grief with major depressive disorder. Qualitative studies explored themes of spirituality and mindfulness. There were 17 controlled studies, including 13 randomized controlled trials. Findings were eclectic, with evidence supporting mindfulness techniques in a group format for emotional and life satisfaction outcomes; an individual, function-based therapy addressing sleep to improve emotion and function; an individual, writing-based emotional expression therapy for short-term improvement in emotion and function; nortriptyline for the treatment of bereavement-related major depressive disorder; a group-based, complicated grief therapy for this condition; an internet-based CBT intervention for prolonged grief; and pharmacotherapy for cardiovascular changes during bereavement. These findings highlight the small literature of methodologically strong intervention studies addressing spousal bereavement in older adults and the need for greater exploration of relevant biological, social, cognitive and behavioral factors to improve short and long term health outcomes.

Abstract
OBJECTIVES This study investigated whether and to what extent widowhood status is related to engagement in advance care planning (ACP), and further whether race/ethnicity moderated the relation. METHODS We analyzed a total of 11,257 older Americans from the Health and Retirement Study using random-effect regression models after controlling for covariates and year-fixed effects. RESULTS We found that both being a widow/widower ever and having been widowed for a longer period of time were associated with a higher probability of engagement in ACP. Specifically, we found that a one-year increase in the number of years since spousal death was associated with 1.02 (p < 0.05, 95% CI = 1.00, 1.03) changes in the odds ratios of informal ACP; however, inclusion of a quadratic term indicated that this association reversed after the peak. Moreover, our findings suggested a moderating effect of race/ethnicity on the relations of the length of time since spousal loss with engagement in ACP. Specifically, the odds of widowed non-Hispanic Blacks discussing with someone the care or medical treatment (informal ACP) and having a living will (formal ACP) were 0.96 (p < 0.05, 95% CI = 0.93, 1.00) and 0.88 (p < 0.05, 95% CI = 0.79, 0.97) times that of non-widowed non-Hispanic Whites. Compared with their non-Hispanic White counterparts, widowed non-Hispanic Blacks were less likely to engage in ACP, and the negative relations were exacerbated when they became widows/widowers. CONCLUSION We elaborated on these findings and discussed their implications for understanding the moderating effect of race/ethnicity on the relation between late-life widowhood and engagement in ACP. In order to develop programs that enhance engagement in ACP and reduce racial/ethnic disparities, research must incorporate intersectionality theory with attention to motivations and decision-making style among diverse widows/widowers. The findings from this study could help inform policy makers when developing public health programs and health care reimbursement programs that enhance engagement in ACP among widows/widowers.

Abstract
BackgroundThe negative impacts of spousal bereavement on the emotional health of the elderly (e.g., depression and anxiety) have been revealed. However, whether widowhood impairs emotional cognition among the elderly is less known. The purpose of this study is to reveal the emotional cognitive deficits among the widowed elderly.MethodsIn this study, we recruited 44 widowed elderly (WE) and 44 elder couples (non-widowed elderly, NWE) and examined their emotional cognition including attention and visual working memory, which were measured by the visual search task and delayed-match-to-sample task, respectively. Three kinds of emotional faces (i.e., sad, angry, and happy) were adopted as the attentional or mnemonic targets.ResultsIt revealed that WE had a general deficit in search efficiency across emotional types, while they showed mnemonic deficits in negative faces but not positive faces. Furthermore, the modeling analysis revealed that the level of depression or state anxiety of the elderly moderated the effects of widowhood on the deficits of mnemonic processing, i.e., the deficits were only evident among WE with the high level of depression or state anxiety.ConclusionThese findings reveal the attentional deficits in sad, angry, and happy faces and the mnemonic deficits in sad and angry faces among elderly who suffer from widowhood and point out the important role of emotional problems such as depression and state anxiety in modulating these emotional cognitive deficits.

Abstract
OBJECTIVES The spousal relationship is one of the most important social contexts in old age, and the loss of a spouse/partner is associated with stress and cognitive decline. In the present study, we examined whether social relationships can buffer potential negative effects of spousal loss on cognition. We examined the role of social network, social activities, and perceived deficiencies in social relationships (loneliness). METHOD We used longitudinal data between 1998 and 2012 from 2,074 participants of the Health and Retirement Study, who had experienced spousal loss during the study period. Multilevel modeling was used to examine how time-varying indicators of social network, social activities, and loneliness were related to age-related trajectories of episodic memory prior to and after spousal loss. Analyses controlled for gender, race/ethnicity, education, time-varying functional health, and being repartnered/remarried. RESULTS Having children living within 10 miles and providing help to others buffered negative effects of widowhood on episodic memory. In addition, within-person increase in providing help to others buffered against decline in episodic memory after spousal loss. Having friends in the neighborhood, more frequent social visits, providing help to others, volunteering, and lack of loneliness were related to higher episodic memory, while having relatives in the neighborhood was related to lower episodic memory. DISCUSSION Our findings suggest that social networks, social activities, and loneliness are related to levels of cognitive function at the time of spousal loss and that social relationships can buffer negative effects of spousal loss on cognitive function. Implications for future research are discussed.

Abstract
OBJECTIVE Although qualitative aspects of interpersonal networks, such as diversity or closeness, can protect the health of older adults, their association with cognitive health remains unclear. This study examined the concurrent and time-lagged association between intra-individual changes in global cognition and social network diversity, while considering emotional closeness. METHODS In this 10-year study, we obtained six-wave, biennial data from the National Institute for Longevity Sciences, Longitudinal Study of Aging. Data from 808 community-dwelling, cognitively intact adults aged 65 or older at baseline were analyzed. Global cognition was assessed using the Mini-Mental State Examination (MMSE). Social network diversity scores were assessed using a social convoy model, comprising three closeness levels: inner (closest), middle (second closest), and outer (least close). RESULTS The mean age of the respondents was 72.0 ± 4.4 years at baseline, and 50.1% were male. A fixed-effects model showed that intra-individual change in total (coefficients, B: 0.10; standard error [SE]: 0.05; p = .042) and inner (B: 0.25; SE: 0.07; p < .001) social network diversity was significantly associated with MMSE score decline, even after adjusting for covariates. Yet, in time-lagged models, diversity and MMSE score changes were not significantly associated during the subsequent two years. CONCLUSION Older adults' global cognition declined when the diversity of their closest social network decreased. This may be a promising marker for early cognitive decline in older adults. Indeed, their closest networks are relatively unlikely to decline as part of normal aging or diseases except dementia.

Abstract
This study provides novel insights into older adults' cognitive functioning before and after widowhood onset and possible effect channels. It further examines gender heterogeneity in the adaptation to (anticipated or actual) spousal bereavement, comparing objective evidence with subjective evidence of cognitive abilities. We used longitudinal data of up to 26,584 participants of the Health and Retirement Study, aged over 50 at recruitment, assessed biennially between 1998 and 2016. Two-way fixed effects with dynamic treatment effects were estimated for various cognitive measures, including six aggregated indices and six single item scales. After adjusting for effect channels including depression, social vulnerability, and stress, there remained significant widowhood effects on older adults' cognitive health. Using single item scales, we established the adverse contemporaneous and adaptation effects on bereaved older females' short-term memory, semantic memory, and numeracy. For bereaved older males, working memory and focus-of-attention deteriorated after widowhood onset. Meanwhile, subjective memory rating remained intact, contrary to objective evidence. We conclude that cognitive transitions to and from widowhood can exhibit distinctive patterns across objective and subjective cognitive domains. With the effect channels in mind, cognitive intervention for widowed older adults should be tailored to the temporal distance to spousal loss, gender, and task.

Abstract
Widowhood is a catastrophic event at any stage of life for the surviving partner particularly in old age, with serious repercussions on their physical, economic, and emotional well-being. This study investigates the association of marital status and living arrangement with depression among older adults. Additionally, the study aims to evaluate the effects of factors such as socio-economic conditions and other health problems contributing to the risk of depression among older adults in India. This study utilizes data from the nationally representative Longitudinal Ageing Study in India (LASI-2017-18). The effective sample size was 30,639 older adults aged 60 years and above. Descriptive statistics and bivariate analysis have been performed to determine the prevalence of depression. Further, binary logistic regression analysis was conducted to study the association between marital status and living arrangement on depression among older adults in India. Overall, around nine percent of the older adults suffered from depression. 10.3% of the widowed (currently married: 7.8%) and 13.6% of the older adults who were living alone suffered from depression. Further, 8.4% of the respondents who were co-residing with someone were suffering from depression. Widowed older adults were 34% more likely to be depressed than currently married counterparts [AOR: 1.34, CI 1.2-1.49]. Similarly, respondents who lived alone were 16% more likely to be depressed compared to their counterparts [AOR: 1.16; CI 1.02, 1.40]. Older adults who were widowed and living alone were 56% more likely to suffer from depression [AOR: 1.56; CI 1.28, 1.91] in reference to older adults who were currently married and co-residing. The study shows vulnerability of widowed older adults who are living alone and among those who had lack of socio-economic resources and face poor health status. The study can be used to target outreach programs and service delivery for the older adults who are living alone or widowed and suffering from depression.

Abstract
While widowhood is known to be associated with poorer physical and mental health outcomes, studies examining the association of widowhood with cognition have yielded mixed results. This review aimed to elucidate the link between widowhood and cognitive decline. A systematic search of Medline, Embase, PsycInfo, CINAHL and Scopus (until December 2020) was conducted to identify studies on the association between widowhood (vs. being married) and cognition in cognitively healthy adults aged 50 +. A cross-sectional meta-analysis (of 10 studies; n = 24,668) found a significant association of widowhood with cognition (g = - 0.36, 95% CI [- 0.47, - 0.25], p = < 0.001). Meta-regressions suggested that study design, cognitive domain measured, sample age, difference in mean age between widowed and married groups, and study continent did not account for observed heterogeneity. A longitudinal meta-analysis (of 3 studies; n = 10,378) found that the "continually widowed" group (from baseline to follow-up) showed significantly steeper declines in cognition compared to the "continually married" group (g = - 0.15, 95%CI [- 0.19, - 0.10], p = < 0.001). Findings indicate that widowhood may be a risk factor for cognitive decline. As there are no effective treatments for cognitive impairment, studying mechanisms by which widowhood might be associated with poorer cognition could inform prevention programs for those who have experienced spousal bereavement.

The Association between Widowhood and Cognitive Function among Chinese Elderly People: Do Gender and Widowhood Duration Make a Difference? Healthcare (Basel) 2021; 9:healthcare9080991. [PMID: 34442128 PMCID: PMC8392527 DOI: 10.3390/healthcare9080991] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 07/27/2021] [Accepted: 07/29/2021] [Indexed: 12/27/2022] Open
Abstract
Few studies have examined the effects of widowhood on cognitive function in Chinese elderly individuals. We conducted a longitudinal study to assess the association between widowhood and cognitive function and further explored gender differences in this association and the impact of widowhood duration. The analytical sample consisted of 5872 Chinese elderly people who participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and were followed up from 2005 to 2014. We used the Chinese version of the Mini-Mental State Examination (MMSE) to assess cognitive function. Widowhood duration was calculated from the self-reported year at which the spouse passed away. Multilevel growth models were employed to estimate the association between widowhood and cognitive function while adjusting for many demographic and socioeconomic characteristics. Widowhood status was associated with cognitive decline among Chinese elderly individuals after adjusting for covariates (B = −0.440, 95% CI −0.727 to −0.152), and this association was only statistically significant among men (B = −0.722, 95% CI −1.104 to −0.339). Being widowed for 5 years or less (B = −0.606, 95% CI −1.112 to −0.100), 16–20 years (B = −0.937, 95% CI −1.685 to −0.190), and 21+ years (B = −1.401, 95% CI −1.967 to −0.834) predicted worse cognitive function in men, while being widowed for more than 21+ years (B = −0.655, 95% CI −1.186 to −0.124) was associated with cognitive decline in women. More attention should be directed towards widowed men and long-term widowed elderly individuals.

Abstract
BACKGROUND Evidence of the association between marital status and cognitive function in Chinese older adults is limited. AIMS To examine the relationship between marital status and cognitive function and to explore the role of gender amongst older adults from three Chinese communities. METHODS A total of 1376 participants aged 60 years or over were included in this cross-sectional study. Cognitive function was assessed using the Chinese version of the mini-mental state examination (MMSE). Marital status and other variables were collected using a standardized questionnaire. Multiple linear regression models were used to examine associations between marital statuses and cognitive function amongst the target population. The moderating role of gender in these potential associations has also been explored. RESULTS In univariate linear regression models, compared to being married, both being widowed (β [95% CI]: -1.46[-2.78 to - 0.13]) and being single (β [95% CI]: - 4.88[-6.43 to - 3.38]) were associated with lower MMSE scores. After adjustment for confounding factors, the significant association of being widowed with MMSE scores disappeared (β [95% CI: - 0.08[- 1.04 to 0.86]), but the association of being single with MMSE scores still existed (β [95% CI]: - 1.87[- 3.17 to - 0.58]). Furthermore, the association of being single with MMSE scores was statistically significant in men (β [95% CI]: - 5.25[- 7.17 to - 3.33]) but not in women (β [95% CI: 0.88[- 0.87 to 2.64]). DISCUSSION AND CONCLUSIONS Being single was associated with poorer cognitive function compared with their married counterparts in older Chinese men but not in women. More preventive measurements should be implemented for single men to reduce or delay cognitive decline. This is particularly important in the context of an aging population in China.

Abstract
BACKGROUND Widowhood is a distressful life event that is associated with loneliness in older adults. However, widowhood is not a binary event, and little is known about the role of widowhood duration in loneliness and about the relationship between widowhood duration and loneliness in different age and sex groups. Given the increases in aging population and in widowed older adults in China, we examined whether and how widowhood and widowhood duration were associated with loneliness in different age and sex groups among Chinese older adults. METHODS Five waves of Chinese Longitudinal Healthy Longevity Survey 2002-2014 were used. The analysis included 34,440 sampled individuals aged 65 and above. Random intercept ordered logistic models were used to examine relations between widowhood, its duration and loneliness in the entire sample and by age and sex groups. RESULTS Results show that with a wide set of covariates controlled for, widowhood was a significant correlate of loneliness in older adults (OR = 2.34, p < .001); and those who were remarried after widowhood were less likely to be lonely compared to their not-remarried counterparts (OR = 0.47, p < .001). In addition, widowhood was associated with more than twice greater odds of loneliness in the first couple of years following bereavement of spouse (OR = 3.09, p < .001) compared to the currently married older adults. The increased odds ratio of loneliness slightly decreased with the length of widowhood, but it was still significant, even after 40 years of bereavement (OR = 1.96, p < .001). CONCLUSIONS These findings are mostly consistent across age and sex groups. In conclusion, this study sheds light on the relationship between widowhood duration and loneliness and the role of remarriage in widowed older adults' loneliness based on a nationwide survey in China. Widowhood has an acute and long-lasting effect on loneliness in older adults. Remarriage after widowhood could largely reduce or offset the risk of loneliness.

Abstract
BACKGROUND This study aims to clarify the association between marital status and dementia in Japan, adjusting for socioeconomic, lifestyle, and lifestyle-related disease factors. METHODS Data from the Japanese Toyama Dementia Survey were used. Individuals aged ≥65 years living in Toyama Prefecture were randomly selected, and 1171 participants were analysed, with a sampling rate of 0.5%. The participants' marital status, socioeconomic status, lifestyle factors, and lifestyle-related diseases were assessed. The odds ratio (OR) of marital status for each lifestyle factor and medical histories were calculated by logistic regression analysis. The OR of marital status for dementia was also calculated by logistic regression analysis. RESULTS The prevalence of dementia was 7.4% for married, and 20.6% for non-married participants. Non-married participants showed a higher prevalence of a history of stroke than married participants. The age- and sex-adjusted OR of marital status for dementia was 1.99 (95% confidence interval (CI) 1.24-3.18) for non-married compared with married participants. Following variable adjustments, the OR for dementia was higher for non-married participants (adjusted OR 1.71; 95% CI 1.03-2.85). CONCLUSIONS Non-marital status was an independent risk factor for dementia in Japan even after adjusting for socioeconomic, lifestyle, and lifestyle-related disease factors. Non-married people were more likely to have dementia because of their history of stroke.

Abstract
Late-life marital status is associated with cognitive aging; however, the influence of life course marital biography (i.e., changes in marital status) on late-life cognitive trajectories, as well as gender differences in the effects of marital biography, remain to be explored. Associations between (a) marital status at study baseline (currently married, previously married, never married) and (b) retrospectively reported life course marital biography (i.e., age at first marriage, time spent unmarried following initial marriage, history of divorce, history of widowhood) and up to 20 years of subsequent episodic memory trajectories were examined using latent growth curve models in 3,061 participants aged 51 + in the Health and Retirement Study 2017 Life History Mail Survey. Gender differences were examined with multiplicative interaction terms and stratified models. Participants who were married at study baseline demonstrated higher initial memory than previously and never married individuals. Older age at first marriage and shorter duration spent unmarried were each associated with better initial episodic memory among previously married individuals only; longer duration spent unmarried was associated with slower memory decline. Stratified models suggested that these associations may be driven by women. These results highlight the importance of considering multiple aspects of marital biography, not just current marital status, in cognitive aging research. Marital biography may have an enduring influence on cognitive aging, particularly among previously married older women. Future work is needed to identify mechanisms (e.g., socioeconomic resources, cognitive stimulation, self and spousal health, emotional support) through which marital histories influence cognitive aging.

Abstract
BACKGROUND Greater cognitive performance has been shown to be associated with better mental and physical health and lower mortality. The present study contributes to the existing literature on the linkages of self-perceived income sufficiency and cognitive impairment. Study also provides additional insights on other socioeconomic and health-related variables that are associated with cognitive impairment in older ages. METHODS Data for this study is derived from the 'Building Knowledge Base on Population Ageing in India'. The final sample size for the analysis after removing missing cases was 9176 older adults. Descriptive along with bivariate analyses were presented to show the plausible associations of cognitive impairment with potential risk factors using the chi-square test. Also, binary logistic regression analysis was performed to provide the relationship between cognitive impairment and risk factors. The software used was STATA 14. RESULTS About 43% of older adults reported that they had no source of income and 7.2% had income but not sufficient to fulfil their basic needs. Older adults with income but partially sufficient to fulfil their basic needs had 39% significantly higher likelihood to suffer from cognitive impairment than older adults who had sufficient income [OR: 1.39; OR: 1.21-1.59]. Likelihood of cognitive impairment was low among older adults with asset ownership than older adults with no asset ownership [OR: 0.83; CI: 0.72-0.95]. Again, older adults who work by compulsion (73.3%) or felt mental or physical stress due to work (57.6%) had highest percentage of cognitive impairment. Moreover, older adults with poor self-rated health, low instrumental activities of daily living, low activities of daily living, low subjective well-being and low psychological health were at increased risk for cognitive impairment. CONCLUSION The study highlights the pressing need for care and support and especially financial incentives in the old age to preserve cognitive health. Further, while planning geriatric health care for older adults in India, priority must be given to financially backward, with no asset ownership, with poor health status, older-older, widowed, and illiterate older individuals, as they are more vulnerable to cognitive impairment.

Abstract
Objectives: This study sought to explore changes in longitudinal cognitive status in relation to baseline measures of intimacy and sexuality in cognitively intact, married older adults.Methods: Baseline intimacy and sexuality survey data from 155, cognitively intact, married, older adults were collected using a novel survey instrument that explored the domains of: 1) romance with one's partner, 2) sexual satisfaction, 3) beliefs about sexuality, and 4) social support and emotional intimacy. These data were analyzed in relation to change in cognitive status over a 10-year follow-up period using binary logistic regression modeling. Exploratory factor analysis was used to assess the shared variance of survey items attributable to intimacy and sexuality without specification of an a priori hypothesis regarding the association of intimacy and sexuality with future change in cognitive status.Results: Over the 10-year study period, 33.5% (n = 52) of individuals developed cognitive impairment. Participants with greater sexual satisfaction scores at baseline were statistically less likely to convert from cognitively intact to mild cognitive impairment or dementia in the future (p = .01). The domains of romance with one's partner, beliefs about sexuality, and social support/emotional intimacy were not predictive of future longitudinal changes in cognitive status.Conclusions: Sexual satisfaction is associated with longitudinal cognitive outcomes in cognitively intact, married, older adults.Clinical implications: Clinicians should routinely assess for sexual satisfaction among older adults and refer to appropriate providers, such as couples or sex therapists, when appropriate.

Abstract
Understanding the consequences of marital experiences for individual mental health provides insight into how social relationships shape individual wellbeing. Using newly available, clinically validated diagnostic interviews with more than 10,000 respondents integrated with the longitudinal Chitwan Valley Family Study (CVFS), we assess the associations between marital experiences, intimate partner violence (IPV), and mental health and how they differ by gender in a setting of universal marriage-Nepal. Particularly novel, we integrate measures of arranged marriage, IPV, and marital quality into a single comprehensive analysis of the marital experiences shaping subsequent depression. This study reveals that becoming married can be positively associated with major depressive disorder (MDD) for women. IPV is a strong and independent risk factor for depression, but it only mediates a small portion of the consequences of marriage on depression. Among women, having no say at all in the selection of a spouse is also a strong and independent risk factor for depression, and IPV can only mediate a small portion of the consequences of arranged marriage on depression. We also investigate the associations between the positive (i.e., husband-wife emotional bond) and negative (i.e., spousal criticism and disagreement) dimensions of marital quality and depression. Frequent spousal disagreement significantly increases depression for women, but strong husband-wife emotional bond is not significantly associated with depression. Overall, the associations between marital experiences and mental health should be understood as contingent on both gender and the social contexts of marriage. Depending on these factors, specific marital experiences have the potential to increase transitions to depression, not just protect from depression.

Abstract
Objectives: This study examined the joint trajectories of behavioral risk factors (smoking, alcohol drinking, and body mass index) and their associations with cognitive function trajectories among older African Americans and white Americans. Methods: Data from the Health and Retirement Study (1998-2014) were used. Group-based mixture modeling and multinomial logistic regression analysis were performed. Results: Three joint trajectories of behavioral risk factors (overweight, smoking and drinking, and drinking and overweight) and three cognitive function trajectories (low, moderate, and high) were identified. A significantly higher percentage of African Americans were in the "overweight," "smoking and drinking," and "low" cognitive functioning groups as measured by the total cognition composite score compared to white Americans. After accounting for covariates, the "drinking and overweight" group was associated with the "moderate" or "high" cognitive functioning group. Discussion: Future interventions targeting the combinations of behavioral risk factors are needed to promote healthy aging among high-risk populations.

Abstract
Background Despite there is growing evidence focusing on health inequalities in China, socioeconomic inequalities in cognitive impairment among older adults have received little attention. This study aims to measure socioeconomic inequalities in cognitive impairment among Chinese older adults, and determine the contributing social factors to the inequalities. Methods A cross-sectional analysis was performed using data from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS). A total of 10,556 older adults aged 65 and over were included in the study. The prevalence of cognitive impairment was measured by using the Chinese version of the Mini-Mental State Examination. The socioeconomic inequalities in cognitive impairment were illustrated and quantified by the concentration curve and normalized concentration index. Multivariate logistic regression was conducted to identify the associated factors of cognitive impairment. And decomposition analysis was further applied to decompose the contribution of each determinant to the observed inequalities in cognitive impairment. Results The study indicated that the prevalence of cognitive impairment among Chinese older adults was 18.95%. The overall concentration index for cognitive impairment was − 0.046, which suggested a higher concentration of cognitive impairment among socioeconomically disadvantaged older adults. The results showed the prevalence of cognitive impairment was associated with sex, age, marital status, education level, occupation, economic status, emotional support, financial support, living arrangement, and participation in informal activities. Decomposition results further revealed the contributions of the determinants to the inequalities in cognitive impairment. Specifically, age (131.61%), marital status (85.68%), emotional support (84.85%), education level (39.73%), occupation (21.24%), sex (17.25%), financial support (− 4.19%), economic status (1.02%), living arrangement (0.88%), and informal activities (0.30%) have varying degrees of contributions to the inequality in cognitive impairment. Conclusion This study sheds light on the pro-rich inequality in cognitive impairment among older adults in China. It suggests that policymakers should pay more attention to older adults who are female, old-old, widowed, illiterate, economically disadvantaged, with no social support, and less socially involved. Also, more targeted interventions should be undertaken to improve the socioeconomic conditions of these vulnerable individuals and strengthen their ability to cope with the risk of cognitive impairment.

Anhedonia as a Potential Risk Factor of Alzheimer's Disease in a Community-Dwelling Elderly Sample: Results from the ZARADEMP Project. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18041370. [PMID: 33546118 PMCID: PMC7913238 DOI: 10.3390/ijerph18041370] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 01/22/2021] [Accepted: 01/30/2021] [Indexed: 12/18/2022]
Abstract
(1) Introduction: Dementia is a major public health problem, and Alzheimer's disease (AD) is the most frequent subtype. Clarifying the potential risk factors is necessary in order to improve dementia-prevention strategies and quality of life. Here, our purpose was to investigate the role of the absence of hedonic tone; anhedonia, understood as the reduction on previous enjoyable daily activities, which occasionally is underdetected and underdiagnosed; and the risk of developing AD in a cognitively unimpaired and non-depressed population sample. (2) Method: We used data from the Zaragoza Dementia and Depression (ZARADEMP) project, a longitudinal epidemiological study on dementia and depression. After excluding subjects with dementia, a sample of 2830 dwellers aged ≥65 years was followed for 4.5 years. The geriatric mental state examination was used to identify cases of anhedonia. AD was diagnosed by a panel of research psychiatrists according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. A multivariate survival analysis and Cox proportional hazards regression model were performed, and the analysis was controlled by an analysis for the presence of clinically significant depression. (3) Results: We found a significant association between anhedonia cases and AD risk in the univariate analysis (hazard ratio (HR): 2.37; 95% CI: 1.04-5.40). This association persisted more strongly in the fully adjusted model. (4) Conclusions: Identifying cognitively intact individuals with anhedonia is a priority to implement preventive strategies that could delay the progression of cognitive and functional impairment in subjects at risk of AD.

Abstract
Background The study investigated sex differences in cognitive outcomes at 90 days after first-ever stroke using data from a population-based sample. Methods and Results The study sample consisted of 1227 participants from the 2009-2016 Brain Attack Surveillance in Corpus Christi project (south Texas, United States) who had first-ever ischemic stroke or intracerebral hemorrhage and survived 90 days after stroke. Poststroke cognitive function was assessed by the Modified Mini-Mental State Examination (3MSE) (range: 0-100; dementia: <78). The associations of sex with dichotomized and continuous outcomes were examined using logistic regression and tobit regression, respectively. Inverse probability weighting and multiple imputation were used to deal with missing data. The study sample was evenly distributed by sex, and primarily composed of Mexican Americans (59.1%) and non-Hispanic whites (34.1%). Women scored 2.96 points worse on the 3MSE than men at 90 days poststroke (95% CI, -3.99 to -1.93). The prevalence of dementia was 27.6% for men (95% CI, 23.5%-31.6%) and 35.6% for women (95% CI, 31.5%-39.7%), and the unadjusted odds ratio (OR) of dementia comparing women with men was 1.45 (95% CI, 1.24-1.69). The association was attenuated after adjustment for sociodemographic, stroke, and prestroke characteristics (OR, 0.82; 95% CI, 0.61-1.09). Conclusions Women had worse cognitive outcomes than men at 90 days poststroke. The differences were attributable to sociodemographic and prestroke characteristics, especially widowhood status. Potential mechanisms linking widowhood to dementia in the acute poststroke stage warrant further investigation to inform interventions addressing the unique care needs of women stroke survivors with dementia and cognitive dysfunction.

Abstract
Objective: Lack of social support is linked to lower cognitive function and cognitive decline. We investigated the effects of a specific type of social relationship, family ties, on cognitive trajectories in non-Hispanic whites, non-Hispanic blacks, and Hispanics. Methods: Using multiple-group latent growth curve models, we analyzed associations between the number of children/grandchildren/siblings/other relatives contacted within the past month at baseline and cognitive trajectories in 1420 older adults who were nondemented at baseline. Language, memory, and visuospatial abilities were assessed at baseline and at 18- and 24-month follow-ups for up to six visits. Inferential analyses assessed the differential effects of sex/gender and race/ethnicity for each family tie. Results: Independent of all covariates, contact with more relatives was associated with better initial memory (b = .01) and language functioning (b = .01) across race/ethnicity and sex/gender. Conclusion: The size of peripheral rather than immediate family networks may be more likely to affect cognitive function in older adults.

Abstract
This study tested the main effect model and the stress-buffering model of the mechanisms by which social support affects bereaved single older adults' depression. Data from the National Social Life, Health, and Aging Project (Wave 2; N = 621) were used to test a latent moderated structural equation model that explores the interaction between grief reactions and social support on bereaved single older adults' depression in the US. The findings provide evidence for the stress-buffering model (i.e., the relationship between grief reactions and depression, which was strongly positive when social support was low, turned negative when social support was high).

Abstract
Healthy lifestyles are promising targets for prevention of cognitive aging, yet the optimal time windows for interventions remain unclear. We selected a case-control sample nested within the Nurses' Health Study (starting year 1976, mean age = 51 years), including 14,956 women aged ≥70 years who were free of both stroke and cognitive impairment at enrollment in a cognitive substudy (1995-2001). Cases (n = 1,496) were women with the 10% worst slopes of cognitive decline, and controls (n = 7,478) were those with slopes better than the median. We compared the trajectories of body mass index (weight (kg)/height (m)2), alternate Mediterranean diet (A-MeDi) score, and physical activity between groups, from midlife through 1 year preceding the cognitive substudy. In midlife, cases had higher body mass index than controls (mean difference (MD) = 0.59 units, 95% confidence interval (CI): 0.39, 0.80), lower physical activity (MD = -1.41 metabolic equivalent of task-hours/week, 95% CI: -2.07, -0.71), and worse A-MeDi scores (MD = -0.16 points, 95% CI: -0.26, -0.06). From midlife through later life, compared with controls, cases had consistently lower A-MeDi scores but a deceleration of weight gain and a faster decrease in physical activity. In conclusion, maintaining a healthy lifestyle since midlife may help reduce cognitive decline in aging. At older ages, both deceleration of weight gain and a decrease in physical activity may reflect early signs of cognitive impairment.

Abstract
IMPORTANCE To reduce the rising incidence of clinical impairment due to Alzheimer disease, it is essential to define older adults at highest risk. Widowhood may be an unrecognized factor contributing to accelerated clinical progression along the Alzheimer disease pathway among cognitively unimpaired older adults. OBJECTIVE To determine whether widowhood status and level of brain β-amyloid (ie, the Alzheimer disease pathologic protein) are additively or interactively associated with cognitive decline among cognitively unimpaired older adults. DESIGN, SETTING, AND PARTICIPANTS In this cohort study, 257 married, widowed, and unmarried (ie, never married, divorced, or separated) participants from the Harvard Aging Brain Study longitudinal cohort underwent baseline evaluation of neocortical β-amyloid levels using Pittsburgh compound B positron emission tomography and 4 annual cognitive assessments. Data were collected from September 2010 to February 2017 and analyzed from July 2018 to July 2019. MAIN OUTCOMES AND MEASURES Cognitive performance was measured using the Preclinical Alzheimer Cognitive Composite. RESULTS Of the 257 participants, 153 (59.5%) were women, and the mean (SD) age was 73.5 (6.1) years; 145 participants (56.4%) were married (66 [45.5%] women), 77 (30.0%) were unmarried (56 [72.7%] women), and 35 (13.6%) were widowed (31 [88.6%] women). Compared with married participants, widowed participants demonstrated worsening cognitive performance after adjusting for age, sex, socioeconomic status, depression, and β-amyloid levels (β = -0.11; 95% CI, -0.19 to -0.04; P = .002) with no difference observed between married and unmarried participants. Furthermore, widowed participants with higher baseline β-amyloid levels exhibited steeper cognitive decline (β = -0.22; 95% CI, -0.42 to -0.03; P = .02), indicating both independent and interactive associations of β-amyloid levels and widowhood with cognition. In a secondary model using dichotomous β-amyloid-marital status groupings, the rate of cognitive decline among widowed participants with high β-amyloid was nearly 3 times faster than among married participants with high β-amyloid (widowed, high β-amyloid: β, -0.33; 95% CI, -0.46 to -0.19; P < .001; married, high β-amyloid: β, -0.12; 95% CI, -0.18 to -0.01; P < .001). CONCLUSIONS AND RELEVANCE In a sample of cognitively unimpaired older adults, being widowed was associated with accelerated β-amyloid-related cognitive decline during 3 years. Cognitively unimpaired, widowed older adults were particularly susceptible to Alzheimer disease clinical progression, emphasizing the need for increased research attention and evidenced-based interventions for this high-risk group.

Abstract
OBJECTIVE Social support shows a protective effect against cognitive impairment in older adults. However, the longitudinal relationship between the distinct sources of social support and the incidence of cognitive impairment remains unclear. This study aims to investigate the association between different sources of social support and the incidence of cognitive impairment among older adults in China. METHOD We used longitudinal data (2005-2014) from the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2005-2014, mean follow-up years 5.32 ± 2.64). In total, 5897 participants (aged 81.7 ± 9.7 years, range 65-112 years, 49.0% male) were enrolled. Cognitive impairment was measured by the Mini-Mental State Examination (MMSE). Social support included support from family and friends (marital status; contacts with family and friends; children's visits; siblings' visits, sick care; money received from and money given to children) and the availability of support from social community (social service and social security). We calculated subdistribution hazard ratios (SHR) of cognitive impairment by establishing Cox regression models, adjusting for residence, gender, age, education, participation in physical exercise, activities of daily living, smoking, drinking, negative psychological well-being, baseline cognitive function, occupation, leisure activities, and diseases. RESULTS During a 9-year follow-up, 1047 participants developed cognitive impairment. Participants who were married had a 16.0% lower risk of developing cognitive impairment compared to the widowed older adults after controlling for all covariates, but the protective effect of being married was no longer significant (p = 0.067) when additional adjustment was made for all types of social support. Children's visits were significantly associated with the risk of cognitive impairment after controlling for all types of social support and covariate variables (SHR = 0.808, 95% confidence interval, 0.669-0.975, p = 0.026). CONCLUSION Children's visits were consistently associated with a lower incidence of cognitive impairment in Chinese older adults.

Abstract
OBJECTIVES Given the limited evidence regarding the longitudinal impact of widowhood on cognitive function in later life, the present study aimed to investigate the longitudinal effect of widowhood status on cognitive change among Korean older adults. METHODS The study sample was drawn from a nationally representative data set, the Korean Longitudinal Study of Ageing (KLoSA); it consisted of 3,660 Korean adults aged 60 and over who were married at baseline. Our dependent variable, cognitive function, was measured by the Korean version of the Mini-Mental State Examination (K-MMSE). Widowhood status was measured with the combination of widowhood status and duration. Growth curve models were constructed using five waves of the KLoSA (2006-2014) to examine the longitudinal trajectories of cognitive changes. RESULTS In the unadjusted model, widowed older adults had significantly lower cognitive function than their nonwidowed counterparts regardless of widowhood duration. Adjusting for covariates, results from the growth curve models showed that widowed older adults with widowhood duration 4 to 6 years had a significantly steeper decline in cognitive function than nonwidowed older adults (P < 0.05). CONCLUSIONS These findings suggest that widowhood is detrimental for late-life cognitive function. Further research is required to understand the mechanisms underlying this relationship. Policy and practice implications are discussed according to the cultural context.

Abstract
Abstract Objective: to verify if the prevalence of dementia differs between widowed and non-widowed elderly persons and between genders, and to analyse if there is an association with sociodemographic and clinical characteristics. Method: a retrospective cross-sectional observational study of patients treated at a Behavioral Neurology outpatient clinic from 1999 to 2009 was carried out, employing anamnesis, physical and neurological examination, the Clinical Dementia Rating Scale (CDR) and the Mini Mental State Examination (MMSE). Sociodemographic (schooling and age) and clinical (age of onset of symptoms and time since onset of symptoms, MMSE and CDR) variables were analyzed. The differences were evaluated by the Mann Whitney test, using a significance value of p<0.05. Results: of 208 patients diagnosed with dementia, 73 (35.1%) were widowed and 135 (64.9%) were non-widowed. Those who were widowed were older than those who were non-widowed (p<0.001) when diagnosed with dementia. This difference in age remained when gender (p<0.001), widowed and widowed women (p<0.001) and widowed and non-widowed men (p<0.001) were compared. The time from onset of symptoms to diagnosis was greater in widowed than in non-widowed men [55.6 (± 86.3) vs. 43.4 (± 44.8) months], although the difference was not statistically significant. Widowed patients with dementia had lower schooling, regardless of gender (p<0.05). Conclusion: the prevalence of dementia differed between widowed and non-widowed individuals, being higher among non-widows. There was an association between widowhood and the clinical and sociodemographic characteristics, with differences between the genders. The loss of a spouse can generate different outcomes among men and women, necessitating measures with a specific focus on prevention and strategies of care in dementia.
