Machine learning algorithms to predict mild cognitive impairment in older adults in China: A cross-sectional study

OBJECTIVE

This study aimed to explore the predictive value of machine learning (ML) in mild cognitive impairment (MCI) among older adults in China and to identify important factors causing MCI.

METHODS

In this study, 6434 older adults were selected based on the data of the China Health and Elderly Care Longitudinal Survey (CHARLS) in 2020, and the dataset was subsequently divided into the training set and the test set, with a ratio of 6:4. To construct a prediction model for MCI in older adults, six ML algorithms were used, including logistic regression, KNN, SVM, decision tree (DT), LightGBM, and random forest (RF). The Delong test was used to compare the differences of ROC curves of different models, while decision curve analysis (DCA) was used to evaluate the model performance. The important contributions of the prediction results were then used to explain the model by the SHAP value.The Matthews correlation coefficient (MCC) was calculated to evaluate the performance of the models on imbalanced datasets. Additionally, causal analysis and counterfactual analysis were conducted to understand the feature importance and variable effects.

RESULTS

The area under the ROC curve of each model range from 0.71 to 0.77, indicating significant difference (P < 0.01). The DCA results show that the net benefits of LightGBM is the largest within various probability thresholds. Among all the models, the LightGBM model demonstrated the highest performance and stability. The five most important characteristics for predicting MCI were educational level, social events, gender, relationship with children, and age. Causal analysis revealed that these variables had a significant impact on MCI, with an average treatment effect of -0.144. Counterfactual analysis further validated these findings by simulating different scenarios, such as improving educational level, increasing age, and increasing social events.

CONCLUSION

The ML algorithm can effectively predict the MCI of older adults in China and identify the important factors causing MCI.

Social support receipt as a predictor of mortality: A cohort study in rural South Africa

The mechanisms connecting various types of social support to mortality have been well-studied in high-income countries. However, less is known about how these relationships function in different socioeconomic contexts. We examined how four domains of social support-emotional, physical, financial, and informational-impact mortality within a sample of older adults living in a rural and resource-constrained setting. Using baseline survey and longitudinal mortality data from HAALSI, we assessed how social support affects mortality in a cohort of 5059 individuals aged 40 years or older in rural Mpumalanga, South Africa. Social support was captured as the self-reported frequency with which close social contacts offered emotional, physical, financial, and informational support to respondents, standardized across the sample to increase interpretability. We used Cox proportional hazard models to evaluate how each support type affected mortality controlling for potential confounders, and assessed potential effect-modification by age and sex. Each of the four support domains had small positive associations with mortality, ranging from a hazard ratio per standard deviation of support of 1.04 [95% CI: 0.95,1.13] for financial support to 1.09 [95% CI: 0.99,1.18] for informational support. Associations were often stronger for females and younger individuals. We find baseline social support to be positively associated with mortality in rural South Africa. Possible explanations include that insufficient social support is not a strong driver of mortality risk in this setting, or that social support does not reach some necessary threshold to buffer against mortality. Additionally, it is possible that the social support measure did not capture more relevant aspects of support, or that our social support measures captured prior morbidity that attracted support before the study began. We highlight approaches to evaluate some of these hypotheses in future research.

Better together: Relationship quality and mental health among cardiac patients and spouses

Reductions in marital relationship quality are pervasive post-cardiac event. It is not yet understood how relationship quality is linked to mental health outcomes in couples where one member has established cardiovascular disease (CVD) and the interdependence within dyads is seldom measured. This research is required as psychological distress has been independently linked to CVD incidence, morbidity, and mortality. This study assessed associations of relationship quality with depression and anxiety among patients with CVD and their spouses. Participants completed questionnaires measuring four dimensions of relationship quality and mental health. Data were analyzed using an Actor-Partner Interdependence Model with hierarchical moderation analyses. 181 dyads (N = 362 participants) comprised the study sample. Most patients had coronary artery disease (66.3%) and 25.9% were female. Patients reported higher relationship satisfaction and fewer anxiety symptoms than did spouses. Patients and spouses with high dyadic consensus and affectional expression reported fewer mental health symptoms, but only when the other partner also perceived high levels of consensus and affectional expression in the relationship. Patients and spouses with low dyadic cohesion reported worse mental health symptoms (actor effects), but those effects were no longer significant when both the patient and the spouse appraised the relationship as having high levels of dyadic cohesion. Taken together, relationship quality is linked to mental health symptoms in patients with CVD and their spouses. Longitudinal and experimental studies are now warranted to further substantiate the cross-sectional findings of this study.

Social relationships and epigenetic aging in older adulthood: Results from the Health and Retirement Study

Growing evidence suggests that social relationship quality can influence age-related health outcomes, although how the quality of one's relationships directly relates to the underlying aging process is less clear. We hypothesized that the absence of close relationships as well as lower support and higher strain within existing relationships would be associated with an accelerated epigenetic aging profile among older adults in the Health and Retirement Study. Adults (N = 3,647) aged 50-100 years completed ratings of support and strain in relationships with their spouse, children, other family members, and friends. They also provided a blood sample that was used for DNA methylation profiling to calculate a priori-specified epigenetic aging measures: Horvath, Hannum, PhenoAge, GrimAge, and Dunedin Pace of Aging methylation (DunedinPoAm38). Generalized linear models that adjusted for chronological age, sex, and race/ethnicity and applied a false discovery rate correction revealed that the absence of marital and friend relationships related to an older GrimAge and faster DunedinPoAm38. Among those with existing relationships, lower support from a spouse, child, other family, and friends and higher strain with friends related to an older PhenoAge and GrimAge and faster DunedinPoAm38. In secondary analyses that further adjusted for socioeconomic and lifestyle factors, lower support from other family members and friends was associated with greater epigenetic aging. Findings suggest that the absence of close relationships and lower support within existing relationships-particularly with family members and friends-relate to accelerated epigenetic aging in older adulthood, offering one mechanism through which social relationships might influence risk for age-related declines and disease.

How Healthy Aging and Contact With Children Are Associated With Satisfaction in Middle-Aged and Older Parents in China: A Mediation Analysis

Objectives

This study aims to examine the mediation role of satisfaction with children on the association between contact with children (CCT) and healthy aging among middle-aged and older parents in China.

Methods

Data from 9,575 parents over 45 years old were obtained from the 2018 China Health and Retirement Longitudinal Survey. A multinomial logistic regression model was applied to measure the association between contact, satisfaction, and healthy aging with potential confounders controlled. We used the Sobel-Goodman Mediation test to analyze the mediation role of satisfaction on the association between types of CCT and healthy aging.

Results

Parents with contact with adult children had higher satisfaction with children [for contact weekly (satisfied/unsatisfied): relative risk ratio (RRR) = 2.44, CI = 1.92-3.10] and higher healthy aging [for contact weekly (Q5/Q1): RRR = 1.41, CI = 1.13-1.77]. Satisfaction was strongly related to healthy aging [for satisfied (Q5/Q1): RRR = 3.44, CI = 2.14-5.51], and mediated 19.05% of healthy aging for weekly contact (Sobel test z = 4.338; indirect role = 0.014, CI = 0.011-0.018; direct role = 0.061, CI = 0.029-0.094). Subgroup analysis further revealed that satisfaction with contact played a partial mediating role between monthly contact and healthy aging in female and rural groups.

Conclusions

Monthly CCT is more appropriate for older parents. Satisfaction with children in older parents seems to act as a significant and partial mediator of the relationship between contact and healthy aging. The contribution of satisfaction to healthy aging could be important to be considered and promoted in women and rural older parents, independent of CCT.

Alcohol Use and Blood Pressure Among Older Couples: The Moderating Role of Negative Marital Quality

OBJECTIVES

Spouses often have concordant drinking behaviors and important influences on one another's cardiovascular health. However, little is known about the implications of dyadic drinking patterns for blood pressure, and the marital factors that confer risk or resilience. This article examined links between alcohol use and blood pressure within individuals and opposite-sex couples over time, and whether those links vary by negative marital quality among older adults.

METHODS

Participants were from the nationally representative longitudinal Health and Retirement Study that included 4,619 respondents in 2,682 opposite-sex couples who participated in at least 2 of the waves from 2006 to 2016. Participants reported the number of drinks they typically consume per week, negative marital quality, and had their blood pressure measured via a cuff.

RESULTS

Analyses revealed that greater drinking was associated with increased systolic blood pressure among both husbands and wives. Furthermore, husbands who drank more had higher blood pressure when wives drank more alcohol, whereas there was no association between husbands' drinking and blood pressure when wives drank less alcohol. Interactions with negative marital quality showed that drinking concordance may be associated with increased blood pressure over time in more negative marriages.

DISCUSSION

Findings indicated that spousal drinking concordance, although often associated with positive marital quality, may have negative long-term health effects.

Social Relationships and Adaptation in Later Life

Social relations encompass a complex and dynamic set of characteristics that have been shown to distinctly affect health and quality of life across the lifespan and especially in older adulthood. In this chapter we begin with a brief review of several prominent theories of social relations. Next, we consider how social relations can be understood based on the resource they provide (e.g., contact frequency, social support), the relationship they stem from (e.g., friends, family), the strength of the tie (e.g., strong, weak) as well as the means of communication (e.g., offline, online). We briefly summarize how these characteristics have been shown to uniquely influence health and quality of life in older adulthood. Finally, we contemplate potential clinical applications, provide recommendations for the future and offer final concluding comments.

A pilot feasibility study of Exercising Together© during radiation therapy for prostate cancer: a dyadic approach for patients and spouses

Introduction

Prostate cancer can negatively impact the health of patients and their spouse, particularly early on in the cancer trajectory.

Purpose

To determine the feasibility and acceptability of dyadic exercises during radiation therapy and preliminary efficacy on physical, mental, and relational outcomes for men and their spouses. Exercising Together©, originally designed as a 6-month dyadic resistance training program for couples post-treatment, was adapted for the radiation setting.

Methods

We conducted a single-group pilot feasibility study of Exercising Together© in men scheduled for radiation therapy for prostate cancer and their spouse. Couples attended supervised exercise sessions thrice weekly throughout radiation treatment and were followed up 8 weeks later. Primary outcomes were feasibility and acceptability with secondary outcomes of changes in physical (physical functioning (short physical performance battery (sPPB)), gait speed (m/s), functional capacity (400-m walk (min), physical activity (min/week)), mental (depressive symptoms (CES-D), and anxiety (SCL-90 ANX)), and relationship (Dyadic Coping, Role Overload, and Physical Intimacy Behavior Scales) health outcomes for each partner. Participants completed an evaluation post-intervention.

Results

Ten couples enrolled and 8 completed the intervention, attending 83% of scheduled sessions. Couple satisfaction with the intervention was high (patients: mean difference (MD) = 9.4 ± 1.9 and spouses: MD = 10.0 ± 0.0, on a 1–10 scale). At post-intervention, gait speed (MD = 0.1; 95%CI: 0.1, 0.2; p = 0.003; d = 0.94) and functional capacity (MD = −0.6; 95%CI: −0.9, 0.3; p = 0.002; d = −0.42) improved in patients and sPPB in spouses (MD = 1.3; 95%CI: 0.3, 2.2; p = 0.02; d = 0.71). Total physical activity increased non-significantly for patients and significantly for spouses at post-intervention and decreased at follow-up (MD = 179.6; 95%CI: 55.4, 303.7; p = 0.01; d = 1.35 and MD = −139.9; 95%CI: −266.5, 13.3; p = 0.03; d=1.06). Among patients, anxiety and active engagement significantly improved post-intervention (MD = −2.3; 95%CI: −3.8, 0.7; p = 0.01; d = −0.43 and MD = 2.5; 95%CI: 0.7, 4.3; p = 0.01; d = 0.98, respectively). There were modest effects on other physical, mental, and relationship health domains in patients and spouses.

Conclusion

A modified version of Exercising Together© is a feasible and acceptable program during radiation therapy for prostate cancer and shows preliminary evidence for improvements on physical, mental, and relational health in both patient and spouse. A larger, fully powered randomized controlled trial is warranted and could help shift the landscape toward dyadically targeted interventions.

Social Cost and Health: The Downside of Social Relationships and Social Networks

The research tradition on social relationships, social networks, and health dates back to the beginning of sociology. As exemplified in the classic work of Durkheim, Simmel, and Tönnies, social relationships and social networks play a double-edged-protective and detrimental-role for health. However, this double-edged role has been given unbalanced attention. In comparison to the salubrious role, the deleterious role has received less scrutiny and needs a focused review and conceptual integration. This article selectively reviews the post-2000 studies that demonstrate the harmful physical and mental health consequences of social relationships (intimate relationships and parenthood) and social networks. It uses a parsimonious three-category typology-structural forms, structural composition, and contents-to categorize relationship and network properties and proposes the social cost model, in contrast to the social resource model, to synthesize and integrate the adverse aspects of these properties. It concludes with future research directions.

Study protocol for the Exercising Together© trial: a randomized, controlled trial of partnered exercise for couples coping with cancer

BACKGROUND

Most cancer survivors are married, and cancer strains the physical and mental health of each partner and their intimate relationship. We created a partnered strength training program, Exercising Together©, where the survivor and his/her partner exercise as a team in order to improve physical and mental health of both members of the couple as well as the quality of their relationship. We have not yet determined if Exercising Together© is similarly effective in couples coping with different types of cancer nor if training as a team has unique and added benefits over those derived from supervised group training and/or shared behavior change. The purpose of this study is to determine the unique benefits of Exercising Together© on physical, mental, and relational health in couples coping with breast, prostate, or colorectal cancer.

METHODS

Survivors of prostate, breast and colorectal cancer (N = 294, 98 per cancer site) and their intimate, co-residing partners are recruited to participate in a single-blind, parallel group, randomized trial comparing three exercise groups that train twice per week for 6 months. Couples are randomized to one of three groups: (1) Exercising Together© where partners train as a team in a supervised group setting; (2) separate supervised group exercise classes for survivors or partners, respectively; (3) unsupervised home exercise program provided to each partner. The primary outcome is relationship quality (dyadic coping by the Dyadic Coping scale, emotional intimacy by the Dyadic Adjustment Scale, physical intimacy by the Physical Intimacy Behavior Scale, and symptom incongruence). Secondary outcomes are physical health (% body fat by DXA, serum fasting lipids (triglycerides, HDL, and LDL cholesterol), insulin resistance (HOMA-IR), resting blood pressure, C-reactive protein, TNF alpha, and physical functioning by the short Physical Performance Battery and SF-36) and mental health (depressive symptoms, anxiety, fear of recurrence) of each partner. Outcomes are collected at baseline, mid (3 months), post-intervention (6 months), and follow-up (12 months).

DISCUSSION

Exercising Together© could shift the paradigm of survivorship care toward novel couple-based approaches that could optimize outcomes for each partner because their health is interdependent on each other and their relationship.

Effect of individuals' forecast for their children's economic environment and satisfaction with their relationships with children on their mortality

AIM

The aim of this study is to evaluate if the risk of mortality among the elderly Korean individuals is associated with any of the two intergenerational variables: participants' forecast for their children's economic environment (FCEE) and participants' satisfaction with their relationship with their children (SRC).

METHODS

Data from the Korean Longitudinal Study of Aging (KLoSA) conducted between 2006 and 2016 were examined. In total, 9937 individuals were included at baseline. The FCEE and SRC were measured using an 11-point Likert scale, which were stratified into four levels: "negative" (0-2), "Moderately negative" (3-5), "moderately positive" (6-8) and "positive" (9, 10).

RESULTS

The Cox proportional hazards model was used to calculate hazard ratios of all-cause mortality across different levels of FCEE and SRC while adjusting for other bio-psycho-social variables. Post-hoc subgroup analyses were conducted to examine how potential confounders contribute to the associations found in our study. Multivariate analyses showed that individuals with more negative FCEE were associated with a greater risk of all-cause mortality. Compared with the "positive" FCEE group, the "negative" group showed a 30.6% increase risk of all-cause mortality (hazard ratio = 1.306, 95% confidence interval = 1.066-1.601, P = 0.010).

CONCLUSION

The SRC did not exhibit any significant association with the all-cause mortality per multivariate analyses. More negative FCEE was associated with greater all-cause mortality. The FCEE, an individual's appraisal of the financial climate of their children's generation, may be considered a novel correlate of the all-cause mortality in an elderly population.

Positive and Negative Impacts of the COVID-19 Pandemic on Relationship Satisfaction in Male Couples

Little is known about the impact of the coronavirus pandemic and control measures on gay, bisexual, and other men who have sex with men (GBMSM) couples. The goal of this study was to investigate individual-level relationship satisfaction during the COVID-19 pandemic in a sample of 209 coupled GBMSM in the United States. We analyzed reported happiness and feelings about a relationship's future and assessed the odds of changing relationship happiness and investment associated with pandemic-related life changes (pandemic-related employment change; COVID-19 illness; high-risk of severe illness), using logistic and multinomial logit models. Fifty-five percent of participants (N = 114) reported that their relationship happiness had not changed during the pandemic, but 30% (N = 62) reported increased relationship happiness. 25% (N = 53) reported they had become more invested in their relationship's future during the pandemic, and only one participant reported decreased investment. The odds of increased relationship investment was significantly associated with pandemic-related employment change (adjusted odds ratio (aOR), 95% confidence interval (CI): 2.19 [1.04, 4.61]) and increased sex during the pandemic (aOR: 4.38 [1.55, 12.41]). Those with a pandemic-related employment change also had significantly higher odds of increased relationship happiness than those without a change (aOR: 2.10 [1.01, 4.35]). COVID-19 cases that reported being at higher risk of serious COVID-19 disease had higher odds of decreased relationship happiness than high-risk non-cases (aOR: 6.58 [1.10, 39.39]). Additional research in this area is warranted to minimize the long-term impacts of the pandemic on coupled GBMSM.

Age Differences in Stress, Life Changes, and Social Ties During the COVID-19 Pandemic: Implications for Psychological Well-Being

BACKGROUND AND OBJECTIVES

Experiences of the coronavirus disease 2019 (COVID-19) pandemic and its implications for psychological well-being may vary widely across the adult life span. The present study examined age differences in pandemic-related stress and social ties, and links with psychological well-being.

RESEARCH DESIGN AND METHODS

Participants included 645 adults (43% women) aged 18-97 (M = 50.8; SD = 17.7) from the May 2020 nationally representative Survey of Consumers. Participants reported the extent to which they felt stress related to the pandemic in the last month, the extent to which their lives had changed due to the pandemic, as well as social isolation, negative relationship quality, positive relationship quality, and frequency of depression, anxiety, and rumination in the past week.

RESULTS

Results showed that older people reported less pandemic-related stress, less life change, less social isolation, and lower negative relationship quality than younger people. Greater pandemic-related stress, life change, social isolation, and negative relationship quality were associated with poorer psychological well-being. Poorer social ties (i.e., greater social isolation and negative quality) exacerbated the effects of the COVID-19 pandemic (stress, life change) on psychological well-being.

DISCUSSION AND IMPLICATIONS

Researchers have indicated that older adults may be more vulnerable to COVID-19 pandemic-related stress and social isolation, but this study indicates that young adults may be relatively more vulnerable. Because isolation and negative relationship quality appear to exacerbate the deleterious effects of the COVID-19 pandemic on psychological well-being, reducing social isolation and negative relations are potential targets for intervention.

Within-Couple Personality Concordance Over Time: The Importance of Personality Synchrony for Perceived Spousal Support

OBJECTIVES

Within-couple similarities in personality traits tend to be positively associated with relationship well-being. However, research in this area is typically based on cross-sectional designs, thereby limiting examination of longitudinal personality concordance. Given that life experiences shape within-person change in personality, and that partners within a couple often experience similar life events, investigation of within-couple personality synchrony and associations with marital outcomes is warranted.

METHODS

Using data from 3,988 couples (mean age at baseline = 67.0 years, SD = 9.6), multilevel dyadic growth models estimated within-couple similarity in baseline levels, change, and occasion-to-occasion variability for each of the Big Five personality traits over an 8-year follow-up. Bivariate growth models examined the effect of within-couple similarity on perceived spousal support, accounting for dependency within couples.

RESULTS

Adjusting for baseline age, education, functional ability, and relationship length, analyses revealed within-couple concordance between baseline levels of all 5 personality traits, as well as correlated within-couple fluctuations in neuroticism, extraversion, and openness over time. Similarity in openness, agreeableness, and neuroticism trajectories predicted spousal support. Couples were most similar in openness, showing correlated intercepts, change, and variability, and this longitudinal synchrony was particularly important for perceived spousal support in women.

DISCUSSION

These findings provide evidence for longitudinal personality synchrony over time within older adult couples. Further, concordance in neuroticism, extraversion, and openness predicted perceived spousal support, though there may be some gender differences in personality dynamics and relationship well-being. Effects of similarity were relatively small compared to actor and partner effects of these traits.

Social Support, Strain, and Glycemic Control: A Path Analysis

Social support and strain have been linked with many health outcomes. However, less is known about whether these psychosocial factors are associated with Type 2 diabetes risk. This study uses the Midlife in the United States (MIDUS) dataset to examine the relationship between social support and strain from friends, family members, and spouse/partners and blood hemoglobin A1c levels in married/cohabiting adults who have not been diagnosed with diabetes. In addition, health locus of control is examined as a possible mediator. The study's findings suggest that support from friends is negatively associated with HbA1c levels, indicating a relationship between better glycemic control and social support from friends, and an indirect association for spouse/partner support. A direct effect for internal health locus of control was also found.

Filial discrepancy and mortality among community-dwelling older adults: a prospective cohort study

Objectives: Adult children play a significant role in ageing parents' health and well-being. However, the evidence is mixed regarding whether the parent-child relations will affect older adults' longevity. This study aims to investigate the relationship between filial discrepancy and mortality risk.Method: Data were derived from a prospective cohort study from 2011 to 2017 of US Chinese older adults aged 60 and above in the Greater Chicago area, with a median of follow-up of 5.28 years. Filial discrepancy was assessed by the gap between filial expectation and receipt, including six domains (discrepancy in respect, greet, care, obey, make happy, and financial support). Mortality ascertained during follow-up. Cox proportional hazards models were used.Results: Among 3,021 participants, care expectation was least fulfilled while financial expectation was better fulfilled compared with other filial discrepancy domains. Compared with no respect discrepancy, older adults with respect expectation above receipt had higher risk of mortality (HR, 1.44; 95%CI, 1.07-1.94). Older adults with higher greet expectation than receipt experienced greater risk of mortality (HR, 1.56; 95%CI, 1.16-2.09) than those with no greet discrepancy. Older adults with care receipt above expectation had lower risk of mortality (HR, 0.75; 95%CI, 0.56-1.00).Conclusion: This study extends the relative standards model to investigate mortality outcomes. The findings add new insights to the association between parent-child relations and mortality risk. It is suggested that educational programs could focus on fostering young immigrants' attitude and behavior to provide more respect and greeting for aging parents to strengthen the family protection role.

Relationship quality and 5-year mortality risk

OBJECTIVE

The present study examined positive and negative aspects of relationship quality with one's spouse or partner as predictors of mortality and the role of gender in moderating this link.

METHOD

Data were drawn from 2 waves, 5 years apart, of the National Social Life, Health, and Aging Project (N = 1,734). Positive aspects of relationship quality (frequency of opening up to the partner to talk about worries and relying on the partner) and negative aspects (frequency of the partner making too many demands and criticism by the partner) were assessed. Survival/mortality status was recorded at the time of Wave 2 data collection 5 years later (1,567 alive; 167 deceased). Covariates included sociodemographic variables, relationship type, health status, and the network size of close family relationships and friendships.

RESULTS

Logistic regression analyses showed that negative relationship quality with one's spouse or partner was associated with significantly higher odds for mortality after 5 years (odds ratio [OR] = 1.20, 95% CI [1.03, 1.38], p < .001), after including the statistical covariates. Also, age, gender, education, self-rated health, and medication use were significantly related to mortality. Propensity score matching replicated these findings. Follow-up analyses revealed that criticism from one's spouse or partner, in particular, was linked to a higher mortality risk (OR = 1.44, 95% CI [1.10, 1.88]). Gender did not moderate the relationship-quality-mortality link.

CONCLUSIONS

Negative relationship quality, notably, criticism received from one's spouse or partner, heightens older adults' risk of mortality. These results suggest the value of developing interventions that target reducing expressed criticism in couple relationships. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Chronic Stress and Negative Marital Quality Among Older Couples: Associations With Waist Circumference

Objective

More than a third of the U.S. population of older adults is obese. The present study tests the Dyadic Biopsychosocial Model of Marriage and Health, which hypothesizes that, among married couples, individual and partner chronic stress predicts increased waist circumference and these links are exacerbated in negative quality marriages.

Method

Participants were from the nationally representative longitudinal Health and Retirement Study (HRS). A total of 2,042 married individuals (in 1,098 married couples) completed psychosocial and waist circumference assessments in 2006 and 2010. Analyses examined whether negative marital quality and chronic stress in Wave 1 (2006) were associated with changes in waist circumference over time.

Results

Actor-partner interdependence models revealed that greater partner stress, rather than individuals' own reports of stress, was associated with increased waist circumference over time. Higher perceived negative marital quality among husbands and lower negative marital quality among wives exacerbated the positive link between partner stress and waist circumference.

Discussion

Consistent with the Dyadic Biopsychosocial Model of Marriage and Health, partner stress has direct associations with waist circumference among couples and this link is moderated by negative marital quality. Thus, dyadic perceptions of stress and negative marital quality are important to consider for understanding marriage and obesity.

Social Ambivalence and Disease (SAD): A Theoretical Model Aimed at Understanding the Health Implications of Ambivalent Relationships

The protective influence of social relationships on health is widely documented; however, not all relationships are positive, and negative aspects of relationships may be detrimental. Much less is known about the relationships characterized by both positivity and negativity (i.e., ambivalence). This article provides a theoretical framework for considering the influence of ambivalent relationships on physical health, including reasons why ambivalence should be considered separately from relationships characterized as primarily positive (supportive) or primarily negative (aversive). We introduce the social ambivalence and disease (SAD) model as a guide to understanding the social psychological antecedents, processes, and consequences of ambivalent relationships. We conclude by highlighting gaps in the literature and features of the SAD model that may serve as a guide to future research on potential health-relevant pathways of ambivalent relationships.

Do Older Parents' Relationships With Their Adult Children Affect Cognitive Limitations, and Does This Differ for Mothers and Fathers?

Objectives

Increasing risk for cognitive limitations in later life, along with an aging population, presents critical challenges for caregiving families and health care systems. These challenges urgently call for research examining factors that may protect against or exacerbate cognitive limitations among older adults. We examine the quality of relationships with adult children, a feature of the social environment known to affect physical and mental health and that may also influence the cognitive health of aging parents.

Methods

Using nationally representative panel data from the Americans' Changing Lives survey, we analyze the impact of both emotional support and strain in relationships with adult children on trajectories of cognitive limitations of aging parents.

Results

Higher levels of strain with adult children were linked to higher initial levels of cognitive limitations among mothers but appeared to be protective against increasing cognitive limitations for fathers as they aged.

Discussion

The gender gap in cognitive limitations may be exacerbated among aging parents experiencing high levels of strain with their adult children. These findings point to the importance of taking gender into account and studying whether positive and negative aspects of close social relationships affect older adults.

Social relations and age-related change in memory

Previous research suggests that social relations are associated with age-related memory change. However, social relations are complex and multidimensional, and it is not yet clear which aspects (structure, quality) may be beneficial over time. Further, the strength and direction of associations may differ depending on relationship type (partner, children, other family, friends). Using longitudinal data from the Health and Retirement Study (n = 10,390; Mage = 69, SD = 9.53 at baseline), latent growth curve models tested which aspects of social relations predicted 6-year episodic memory trajectories. Both structure and quality of social relations were associated with initial memory level, such that being married/partnered, reporting more frequent contact with children and friends, reporting less support from family members other than partners and children, and reporting less strain across relationship types were each independently associated with better initial memory. In contrast, only structure was associated with subsequent memory decline. Specifically, being married/partnered and reporting more frequent contact with friends were each independently associated with slower memory decline. No evidence of bidirectionality was found, as baseline memory did not predict subsequent changes in social relations. This longitudinal study helps to clarify which aspects of social relations are most likely to influence late-life episodic memory trajectories. Future intervention studies may focus on increasing social interactions with nonfamily members to minimize memory decline with age. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Rural-Urban Residence and Stage at Breast Cancer Diagnosis Among Postmenopausal Women: The Women's Health Initiative

BACKGROUND

Although social exposures have complex and dynamic relationships and interactions, the existing literature on the impact of rural-urban residence on stage at breast cancer diagnosis does not examine heterogeneity of effect. We examined the joint effect of social support, social relationship strain, and rural-urban residence on stage at breast cancer diagnosis.

METHODS

Using data from the Women's Health Initiative (WHI) (n = 161,808), we describe the distribution of social, behavioral, and clinical factors by rural-urban residence among postmenopausal women with incident breast cancer (n = 7,120). We used rural-urban commuting area (RUCA) codes to categorize baseline residential addresses as urban, large rural city/town, or small rural town, and the surveillance, epidemiology, and end results staging system to categorize breast cancer stage at diagnosis (dichotomized as early or late). We then used univariable and multivariable logistic regression to estimate odds ratios (ORs) and associated 95% confidence intervals (95% CI) for the relationship between rural-urban residence and stage at breast cancer diagnosis. We included separate interaction terms between rural-urban residence and social strain and social support to test for statistical interaction.

RESULTS

Of the social, behavioral, and clinical factors we examined, only younger age at WHI enrollment screening was significantly associated with late stage at breast cancer diagnosis (p = 0.003). Contrary to our hypothesis, rural-urban residence was not significantly associated with stage at breast cancer diagnosis among postmenopausal women ([adjusted OR, 95% CI] for urban compared with small town: 1.08 [0.76-1.53]; large town compared with small town: 1.16 [0.74-1.84]; and urban compared with large town: 0.93 [0.68-1.26]).The associations did not vary by social support or social strain (p for interaction between RUCA and social strain and social support, respectively: 0.99 and 0.17).

CONCLUSIONS

Future studies should examine other potential effect modifiers to identify novel factors predictive or protective for late stage at breast cancer diagnosis associated with rural-urban residence.

The Good, the Bad, and the Indifferent: Physical Disability, Social Role Configurations, and Changes in Loneliness Among Married and Unmarried Older Adults

Objectives: To examine how social role configurations (SRCs)-combinations of the quality of spousal, family, and friend relationships-moderate the association between functional limitations (FLs) and loneliness among married and unmarried older adults and whether this differs by gender. Method: Longitudinal data from the National Social Life, Health, and Aging Project on married (n = 945) and unmarried (n = 443) older adults (aged 57-85 years). Latent class analysis was used to identify SRCs. Tobit regression models examined the associations between FLs, SRCs, and loneliness. Results: Nine SRCs were identified. The effectiveness of SRCs for coping with FLs did not differ by marital status despite higher loneliness among the unmarried. Only for women with FLs did SRCs characterized by negativity/strain exacerbate loneliness. For men with FLs, SRCs characterized by excess positivity/support were problematic. Discussion: These findings underscore the importance of considering how SRCs provide resources for coping with FLs that have gendered implications.

Association of sleep disturbance and sexual function in postmenopausal women

OBJECTIVE

Sleep disturbance and sexual dysfunction are common in menopause; however, the nature of their association is unclear. The present study aimed to determine whether sleep characteristics were associated with sexual activity and sexual satisfaction.

METHODS

Sexual function in the last year and sleep characteristics (past 4 wk) were assessed by self-report at baseline for 93,668 women age 50 to 79 years enrolled in the Women's Health Initiative (WHI) Observational Study (OS). Insomnia was measured using the validated WHI Insomnia Rating Scale. Sleep-disordered breathing (SDB) risk was assessed using questions adapted from the Berlin Questionnaire. Using multivariate logistic regression, we examined cross-sectional associations between sleep measures and two indicators of sexual function: partnered sexual activity and sexual satisfaction within the last year.

RESULTS

Fifty-six percent overall reported being somewhat or very satisfied with their current sexual activity, and 52% reported partnered sexual activity within the last year. Insomnia prevalence was 31%. After multivariable adjustment, higher insomnia scores were associated with lower odds of sexual satisfaction (yes/no) (odds ratio [OR] 0.92, 95% CI, 0.87-0.96). Short sleep duration (<7-8 h) was associated with lower odds of partnered sexual activity (yes/no) (≤5 h, OR 0.88, 95% CI, 0.80-0.96) and less sexual satisfaction (≤5 h, OR 0.88, 95% CI, 0.81-0.95).

CONCLUSIONS

Shorter sleep durations and higher insomnia scores were associated with decreased sexual function, even after adjustment for potential confounders, suggesting the importance of sufficient, high-quality sleep for sexual function. Longitudinal investigation of sleep and its impact on sexual function postmenopause will clarify this relationship.

Older Gay Men and Their Support Convoys

Objective

We used the convoy model and the network type construct to identify the relationship quality profiles found among older gay men and to examine how they define a satisfactory network.

Method

We used a network mapping strategy and in-depth qualitative interviews with 20 participants in Atlanta. During the interviews, all network members were discussed, regardless of relationship or map position.

Results

For participants, having people in their lives with whom they could fully be "out" as gay men (authenticity) was at the root of a quality network. This allowed them to develop emotional closeness (intimacy), which, in part, provided a foundation of social support. Participants' discussion of network quality, which reflected authenticity, intimacy, and social support, revealed high, moderate, and low quality network types.

Discussion

Our findings diversify knowledge of the network type construct, provide a deeper understanding of its qualitative features, and give voice to this often-invisible group, situating meaning within their social-historical context. The findings suggest that the meaning of a quality network is contextual and culturally specific, varying across groups of older adults.

Marital stability, satisfaction and well-being in old age: variability and continuity in long-term continuously married older persons

OBJECTIVES

Recent research shows that the well-documented positive effects of marital stability on well-being and health outcomes are conditional upon the quality of marriage. To date, few studies have explored the relationship between marital satisfaction, well-being and health among very long-term married individuals. This study aims at identifying groups of long-term married persons with respect to marital satisfaction and comparing them longitudinally concerning their well-being outcomes, marital stressors, personality and socio-demographic variables.

METHOD

Data are derived from a survey (data collection 2012 and 2014) with 374 continuously married individuals at wave 1 (mean age: 74.2 years, length of marriage: 49.2 years) and 252 at wave 2. Cluster analyses were performed comparing the clusters with regard to various well-being outcomes. The predictive power of cluster affiliation and various predictors at wave 1 on well-being outcomes at wave 2 was tested using regression analyses.

RESULTS

Two groups were identified, one happily the other unhappily married, with the happily married scoring higher on all well-being and health outcomes. Regression analyses revealed that group affiliation at wave 1 was not any longer predictive of health, emotional loneliness and hopelessness two years later, when taking into account socio-demographic variables, psychological resilience and marital strain, whereas it remained an important predictor of life satisfaction and social loneliness.

CONCLUSION

Marital satisfaction is associated with health and well-being in older couples over time, whereas psychological resilience and marital strain are major predictors explaining the variance of these outcomes.

Physical Disability and Increased Loneliness among Married Older Adults: The Role of Changing Social Relations

Examining the social context of disablement, we investigated how changes in social relations affect loneliness among married older men and women. With longitudinal data on 914 married persons from the National Social Life, Health, and Aging Project (NSHAP), we found that changes in the quality of marital and nonmarital relations moderate the effect of disability on loneliness in unexpected ways. Increases in negative marital quality buffer the effect of physical disability, while increases in nonmarital support exacerbate it. Although not predicted by existing theory, these findings are consistent with some prior work suggesting that health-related stressors, like physical disability, condition the meaning of changes in social relations. We find, however, that negative social relations ameliorate loneliness only among disabled married men; disabled married women experience increased loneliness under similar circumstances. These differences have not been previously identified. We conclude by discussing the gendered nature of the social context of disablement.

The Impact of Relationship Quality on Health-Related Outcomes in Heart Failure Patients and Informal Family Caregivers: An Integrative Review

BACKGROUND

Relationships can have positive and negative impacts on health and well-being. Dyadic relationships between heart failure (HF) patients and their informal family caregivers may affect both patient and caregiver outcomes.

OBJECTIVE

The aim of this study is to synthesize the literature to date on the associations between HF patient-caregiver relationship quality and communication and patient and caregiver health outcomes.

METHODS

An integrative review of the literature was conducted. Computerized literature searches in Medline, PsycInfo, CINAHL, Web of Science, and EMBASE yielded 13 articles of HF patients and caregivers. Included articles were reviewed and double-coded by 2 independent coders.

RESULTS

Included articles measured relationship quality or aspects of communication within an HF patient-caregiver dyad and used both cross-sectional and longitudinal designs. Results of the longest prospective study suggested that better relationship quality between HF patients and their informal family caregivers was related to a reduced risk for mortality in patients. Results of 11 of the 12 other studies were consistent to the reference study, suggesting that better relationship quality and communication were related to reduced mortality, increased health status, less distress, and lower caregiver burden.

CONCLUSIONS

Relationship quality and communication seem to matter in the health and well-being of both HF patients and their informal family caregivers. More research is needed to elucidate mechanisms and to design effective relationship-focused interventions.

Relationship Quality in Non-Cognitively Impaired Mother-Daughter Care Dyads: A Systematic Review

More than 60 million Americans provide care to a family member; roughly two thirds are women providing care to aging mothers. Despite the protective nature of relationship quality, little attention has been given to its role in mother-daughter care dyads, particularly in mothers without cognitive impairment. A systematic appraisal of peer-reviewed, English language research was conducted. Nineteen articles met criteria. When relationship quality is positive, mother-daughter dyads enjoy rewards and mutuality, even when conflict occurs. Daughters grow more emotionally committed to mothers' over the care trajectory, despite increasing demands. Daughters' commitment deepens as mothers physically decline, and mothers remain engaged, emotional partners. When relationship quality is ambivalent or negative, burden, conflict, and blame conspire, creating a destructive cycle. Avenues for continuing study, including utilizing the dyad as the unit of analysis, troubled dyads, longitudinal assessment, and end of life context, are needed before interventions to improve mother-daughter relationship quality may be successfully implemented.

Stress and Negative Relationship Quality among Older Couples: Implications for Blood Pressure

OBJECTIVES

The cardiovascular system may represent a significant pathway by which marriage and stress influence health, but research has focused on married individuals cross-sectionally. This study examined associations among chronic stress, negative spousal relationship quality, and systolic blood pressure over time among middle-aged and older husbands and wives.

METHOD

Participants were from the nationally representative longitudinal Health and Retirement Study. A total of 1,356 (N = 2,712) married and cohabitating couples completed psychosocial and biomeasure assessments in waves 2006 and 2010. Analyses examined whether Wave 1 (2006) relationship quality and stress were associated with changes in blood pressure over time.

RESULTS

The effects of stress and negative relationship quality were dyadic and varied by gender. Husbands had increased blood pressure when wives reported greater stress, and this link was exacerbated by negative spousal relationship quality. Negative relationship quality predicted increased blood pressure when both members of the couple reported negative quality relations.

DISCUSSION

Findings support the dyadic biopsychosocial model of marriage and health indicating: (a) stress and relationship quality directly effect the cardiovascular system, (b) relationship quality moderates the effect of stress, and (c) the dyad rather than only the individual should be considered when examining marriage and health.

Marital Quality and Cognitive Limitations in Late Life

OBJECTIVES

Identifying factors associated with cognitive limitations among older adults has become a major public health objective. Given the importance of marital relationships for older adults' health, this study examines the association between marital quality and change in cognitive limitations in late life, directionality of the relationship between marital quality and cognitive limitations, and potential gender differences in these associations.

METHOD

Latent growth curve models were used to estimate the association of marital quality with change in cognitive limitations among older adults and the direction of the association between marital quality and cognitive limitations using 4 waves of the Americans' Changing Lives survey (N = 841).

RESULTS

Results indicate that more frequent negative (but not positive) marital experiences are associated with a slower increase in cognitive limitations over time, and the direction of this association does not operate in the reverse (i.e., cognitive limitations did not lead to change in marital quality over time). The association between negative marital experiences and cognitive limitations is similar for men and women.

DISCUSSION

The discussion highlights possible explanations for the apparent protective effect of negative marital experiences for older adults' cognitive health over time, regardless of gender.

Social relationships and their biological correlates: Coronary Artery Risk Development in Young Adults (CARDIA) study

OBJECTIVE

Analyses test the hypothesis that aspects of social relationships (quantity of ties, social support and social strain) are associated with differences in levels of biological risk across multiple major physiological regulatory systems and consequently overall multi-systems risk (i.e., allostatic load [AL]).

METHODS

Data are from the Coronary Artery Risk Development in Young Adults (CARDIA) study--a bi-ethnic, prospective, multi-center epidemiological study, initiated in 1985-1986 to track the development of cardiovascular risk in young adulthood (N=5115). At the year 15 follow-up when participants were between 32 and 45 years of age, additional social and biological data were collected; biological data used to assess AL were collected at the Oakland, CA and Chicago, IL sites (N=844).

RESULTS

Social strains were most strongly and positively related to overall AL (Cohen's d=.79 for highest vs. lowest quartile), and to each of its component biological subsystems, independent of social ties and support as well as sociodemographics and health behaviors. Social ties and emotional support were also negatively related to AL (Cohen's d=.33 and d=.44 for lowest vs. highest quartiles of ties and support, respectively) though controls for social strains reduced these associations to non-significance. Social support and social strain were more strongly related to overall AL than to any of its component subscales while social ties were less strongly related to AL and to its component subscales. There was no evidence that effects differed by sex, age or ethnicity.

CONCLUSIONS

Findings focus attention on the particularly strong relationship between social strains and profiles of biological risk and support the cumulative impact of social factors on biological risks, showing larger effects for cumulative AL than for any of the individual biological systems.

Sexual activity and psychological health as mediators of the relationship between physical health and marital quality

OBJECTIVES

The pathways linking spousal health to marital quality in later life have been little examined at the population level. We develop a conceptual model that links married older adults' physical health and that of their spouse to positive and negative dimensions of marital quality via psychological well-being of both partners and their sexual activity.

METHODS

We use data from 1,464 older adults in 732 marital dyads in the 2010-2011 wave of the National Social Life Health and Aging Project.

RESULTS

We find that own fair or poor physical health is linked to lower positive and higher negative marital quality, spouse's health to positive quality, and that own and spouse's mental health and more frequent sex are associated with higher positive and lower negative marital quality. Further, we find that (a) sexual activity mediates the association between own and partner's physical health and positive marital quality, (b) own mental health mediates the association between one's own physical health and both positive and negative marital quality, and (c) partner's mental health mediates the associations of spouse's physical health with positive marital quality. These results are robust to alternative specifications of the model.

DISCUSSION

The results suggest ways to protect marital quality among older adults who are struggling with physical illness in themselves or their partners.

What Type of Social Support Influences Self-Reported Physical and Mental Health Among Older Women?

OBJECTIVE

We examined which types of social support were associated with older women's self-report of physical and mental health and whether the effects of social support were moderated by race/ethnicity.

METHOD

Women completed a health behavior survey that included the Medical Outcomes Study-Short Form-12 (MOS SF-12). Single race/ethnic group regressions examined whether different types of social support were related to health. We also examined Pratt's relative importance measures.

RESULTS

Emotional support had the strongest effect on both physical and mental health, explaining the highest amount of variation, except among African Americans. Race/ethnicity moderated the association of informational support for Asian women's reports of their mental health.

DISCUSSION

For clinicians, assessing individuals' emotional support is important for maintaining or increasing physical and mental health. Clinicians can also assess Asian women's stress, providing informational support accordingly as too much information could be detrimental to their health. For researchers, the inclusion of emotional support items is the most important.

Spousal social support and strain: impacts on health in older couples

Using a nationally representative sample of couples aged 51+ in the United States (N = 1,923 couples), the current study investigated whether both partners' perceptions of relationship support and strain are associated with an individual's self-rated health and functional limitations. The sample had an average age of 67.17 years (SD = 9.0; range 50-97). Actor-Partner Interdependence Models adjusting for couple interdependencies were applied using multilevel models. After accounting for age, education, gender, race, and couple differences in length of marriage, results indicate that individual perceptions of support were significantly associated with higher self-rated health and fewer functional limitations. These individual-level benefits increased if the spouse also perceived positive support and low strain. Finally, the negative association of an individual's perceived support on functional limitations was greater in those with a spouse reporting low levels of perceived strain. Findings are discussed relative to theory on behavioral and psychological pathways between partners' perceptions of support and health.

Marital Conflict in Older Couples: Positivity, Personality, and Health

We examine the implications of health and personality characteristics for late-life marital conflict, using data from the 2010-11 wave of the National Social Life Health and Aging Project (NSHAP), a nationally representative study with data on both partners in 955 marital and cohabitational dyads. Using these data, we relate characteristics of husbands to characteristics of their wives, and vice versa. Wives with husbands in fair or poor physical health are more likely to report high levels of marital conflict, but the reverse is not true. Similarly, wives report more conflict when their husbands are high on Neuroticism, high on Extraversion, and low on a new measure we call Positivity. Our findings point to noteworthy gender differences between men and women in the associations between individual characteristics and levels of marital conflict. We point to differences between husbands' and wives' marital roles as a contributor to these differences.

The convoy model: explaining social relations from a multidisciplinary perspective

PURPOSE OF THE STUDY

Social relations are a key aspect of aging and the life course. In this paper, we trace the scientific origins of the study of social relations, focusing in particular on research grounded in the convoy model.

DESIGN AND METHODS

We first briefly review and critique influential historical studies to illustrate how the scientific study of social relations developed. Next, we highlight early and current findings grounded in the convoy model that have provided key insights into theory, method, policy, and practice in the study of aging.

RESULTS

Early social relations research, while influential, lacked the combined approach of theoretical grounding and methodological rigor. Nevertheless, previous research findings, especially from anthropology, suggested the importance of social relations in the achievement of positive outcomes. Considering both life span and life course perspectives and grounded in a multidisciplinary perspective, the convoy model was developed to unify and consolidate scattered evidence while at the same time directing future empirical and applied research. Early findings are summarized, current evidence presented, and future directions projected.

IMPLICATIONS

The convoy model has provided a useful framework in the study of aging, especially for understanding predictors and consequences of social relations across the life course.

Effects of social ties on self-rated physical health among African American adults

OBJECTIVES

To examine associations between social ties and self-rated physical health among midlife and older African Americans.

METHODS

Cross-sectional analysis of the 2005-2006 Milwaukee African American oversample of the second Midlife Development in the United States (MIDUS II) study. Multivariate logistic regression examined associations between type of social ties (family or friends), their frequency (number of contacts), and their quality (support and strain) with betterself-rated physical health (SRPH). We defined better SRPH to include self-reports of good, very good, or excellent SRPH: this category was compared with fair or poor SRPH. Control variables included demographic factors; social engagement characteristics such as working, volunteering, and caregiving; and measures of social structure such as types of discrimination experience and ratings of neighborhood quality.

RESULTS

In adjusted results, each additional degree of family support was associated with better self-rated physical health (odds ratio [OR], 1.59; 95% confidence interval (CI], 1.14-2.22). Each additional reported incident of daily discrimination was associated with 9% lower odds of reporting better SRPH (OR, 0.91; CI, 0.83-0.99).

DISCUSSION

Results suggest quality of family support may contribute importantly to the health of African Americans. When working with midlife and older African Americans, providers should engage and support families as a vital resource to improve health.

Social partners and momentary affect in the oldest-old: the presence of others benefits affect depending on who we are and who we are with

Links between social relationships and emotional well-being in old age are well documented, but little is known about daily life fluctuations in momentary affective experiences of the oldest-old while interacting with specific social partners. We examined associations between the presence of different types of social partners and moment-to-moment fluctuations in affect in the oldest-old, taking into account individual differences in gender, neuroticism, depressive symptoms, chronic health conditions, and loneliness. Participants (N = 74, M age = 88.7 years, range = 84-102 years, 68% women) provided self-reports concurrently on the presence of social partners and subjective affective states 6 times a day for each of 7 consecutive days (3,071 occasions, in total). Relative to being with other people, time spent alone was associated with lower positive affect in the oldest-old. Being with other family members and friends was associated with more positive affective experiences. Compared with men, women reported more negative affective experiences when they were with their spouses than when their spouses were not present. Individuals with more chronic health problems reported more negative affective experiences when they were with their spouses than not. Participants higher in neuroticism reported more positive affective experiences when they were with their friends, compared with times when their friends were not present. Finally, lonelier individuals reported more positive affective experiences when they were with their spouses than when they were not. These findings suggest that affective experience is a function of individual differences and the type of social partners oldest-old adults interact with in everyday life. We discuss how our findings can be generalized to oldest-olds of different marital statuses, taking into account the proportion of widows in our sample as well as measurement specifics.

Factores psicosociales predictores de la calidad de vida en personas en situación de discapacidad física

El presente estudio correlacional descriptivo se propuso evaluar los factores que determinan la calidad de vida (CV) relacionada con la salud en 78 personas con discapacidad física que vivían en Bogotá, y hacían parte de un proyecto de inclusión laboral dirigido por una ONG. Se evaluó la calidad de vida relacionada con la salud (Cuestionario de Salud SF36 y visita domiciliaria), al igual que las condiciones asociadas a la discapacidad y algunos factores psicológicos (Escala de Autoeficacia Generalizada, Prueba de Imagen Corporal, Inventario de Estilos de Afrontamiento, Prueba de optimismo disposicional, Inventario de Depresión de Beck y Escala de Ansiedad de Zung). Se utilizó un modelo de ecuaciones estructurales para encontrar el poder predictivo de las variables en la calidad de vida. El modelo obtenido predecía un 39% de la varianza, incluyendo en orden de peso relativo aportando variables como condiciones de enfermedad, depresión, afrontamiento centrado en la fantasía, trascendencia, pesimismo, ansiedad y autoeficacia. Se discuten los hallazgos y las limitaciones del estudio.

Implications of marital/partner relationship quality and perceived stress for blood pressure among older adults

OBJECTIVES

Although higher quality marriages are associated with better health outcomes, less is known about the mechanisms accounting for this association. This study examines links among marital/partner quality, stress, and blood pressure and considers both main and moderating effects.

METHOD

Participants from the National Social Life, Health, and Aging Project (N = 1,854; aged 57-85 years) completed in-person interviews regarding their marital/romantic partner relationships and perceived stress. Interviews included blood pressure assessments.

RESULTS

Linear regression models revealed no main effects of spousal/partner quality or stress on blood pressure. However, spousal/partner quality moderated the link between stress and blood pressure. Specifically, there were negative associations between stress and blood pressure among people reporting more confiding, less reliance, and greater demands from spouses/partners.

DISCUSSION

Findings highlight the complexity of relationship quality. Individuals appeared to benefit from aspects of both high- and low-quality spouse/partner relations but only under high levels of stress. Findings are inconsistent with traditional moderation hypotheses, which suggest that better quality ties buffer the stress-health link and lower quality ties exacerbate the stress-health link. Results offer preliminary evidence concerning how spousal ties "get under the skin" to influence physical health.

The right to move: a multidisciplinary lifespan conceptual framework

This paper addresses the health problems and opportunities that society will face in 2030. We propose a proactive model to combat the trend towards declining levels of physical activity and increasing obesity. The model emphasizes the need to increase physical activity among individuals of all ages. We focus on the right to move and the benefits of physical activity. The paper introduces a seven-level model that includes cells, creature (individual), clan (family), community, corporation, country, and culture. At each level the model delineates how increased or decreased physical activity influences health and well-being across the life span. It emphasizes the importance of combining multiple disciplines and corporate partners to produce a multifaceted cost-effective program that increases physical activity at all levels. The goal of this paper is to recognize exercise as a powerful, low-cost solution with positive benefits to cognitive, emotional, and physical health. Further, the model proposes that people of all ages should incorporate the "right to move" into their life style, thereby maximizing the potential to maintain health and well-being in a cost-effective, optimally influential manner.

Socioeconomic status, structural and functional measures of social support, and mortality: The British Whitehall II Cohort Study, 1985-2009

The authors examined the associations of social support with socioeconomic status (SES) and with mortality, as well as how SES differences in social support might account for SES differences in mortality. Analyses were based on 9,333 participants from the British Whitehall II Study cohort, a longitudinal cohort established in 1985 among London-based civil servants who were 35–55 years of age at baseline. SES was assessed using participant's employment grades at baseline. Social support was assessed 3 times in the 24.4-year period during which participants were monitored for death. In men, marital status, and to a lesser extent network score (but not low perceived support or high negative aspects of close relationships), predicted both all-cause and cardiovascular mortality. Measures of social support were not associated with cancer mortality. Men in the lowest SES category had an increased risk of death compared with those in the highest category (for all-cause mortality, hazard ratio = 1.59, 95% confidence interval: 1.21, 2.08; for cardiovascular mortality, hazard ratio = 2.48, 95% confidence interval: 1.55, 3.92). Network score and marital status combined explained 27% (95% confidence interval: 14, 43) and 29% (95% confidence interval: 17, 52) of the associations between SES and all-cause and cardiovascular mortality, respectively. In women, there was no consistent association between social support indicators and mortality. The present study suggests that in men, social isolation is not only an important risk factor for mortality but is also likely to contribute to differences in mortality by SES.

Validating the German version of the Quality of Relationship Inventory: confirming the three-factor structure and report of psychometric properties

Research on psychosocial influences such as relationship characteristics has received increased attention in the clinical as well as social-psychological field. Several studies demonstrated that the quality of relationships, in particular with respect to the perceived support within intimate relationships, profoundly affects individuals' mental and physical health. There is, however, a limited choice of valid and internationally known assessments of relationship quality in Germany. We report the validation of the German version of the Quality of Relationships Inventory (QRI). First, we evaluated its factor structure in a representative German sample of 1.494 participants by means of confirmatory factor analysis. Our findings support the previously proposed three-factor structure. Second, importance and satisfaction with different relationship domains (family/children and relationship/sexuality) were linked with the QRI scales, demonstrating high construct validity. Finally, we report sex and age differences regarding the perceived relationship support, conflict and depth in our German sample. In conclusion, the QRI is a reliable and valid measurement to assess social support in romantic relationships in the German population.

Social networks, social support and burden in relationships, and mortality after breast cancer diagnosis

Though larger social networks are associated with reduced breast cancer mortality, there is a need to clarify how both social support and social burden influence this association. We included 4,530 women from the Women's Health Initiative who were diagnosed with breast cancer between 1993 and 2009, and provided data on social networks (spouse or intimate partner, religious ties, club ties, and number of first-degree relatives) before diagnosis. Of those, 354 died during follow-up, with 190 from breast cancer. We used Cox proportional hazards regression to evaluate associations of social network members with risk of post-diagnosis mortality, further evaluating associations by social support and social burden (caregiving, social strain). In multivariate-adjusted analyses, among women with high but not low social support, being married was related to lower all-cause mortality. By contrast, among women with high but not low social burden, those with a higher number of first-degree relatives, including siblings, parents, and children, had higher all-cause and breast cancer mortality (among caregivers: 0-3 relatives (ref), 4-5 relatives, HR = 1.47 (95% CI: 0.62-3.52), 6-9 relatives, HR = 2.08 (95% CI: 0.89-4.86), 10+ relatives, HR = 3.55 (95% CI: 1.35-9.33), P-continuous = 0.02, P-interaction = 0.008). The association by social strain was similar though it was not modified by level of social support. Other social network members were unrelated to mortality. Social relationships may have both adverse and beneficial influences on breast cancer survival. Clarifying these depends on understanding the context of women's relationships.

Stability and change in the intergenerational family: a convoy approach

There have been fundamental changes in the intergenerational family, and yet families continue to be an important part of people's lives. We use the convoy model to describe the factors that influence supportive relations within intergenerational families, beginning with a description of the changing structure of the intergenerational family. We next outline support exchanges, detailing how personal characteristics, especially gender, race, age and socio-economic status, and situational characteristics, in particular family structure and intergenerational context, influence support exchanges. Instrumental and emotional family exchanges are described, with special attention to the unique circumstances of care-giving in intergenerational families. We also examine the importance of recognising differences in the quality of intergenerational relations, again noting the influence of personal and situational characteristics. Variations in support quality, e.g. positive, negative and ambivalent, and its influence on wellbeing are discussed. As families and individuals change, differences emerge at the individual, family and societal levels. We consider the implications of changes and stability in intergenerational relations and make recommendations about how best to envisage and plan future intergenerational family support. Societies with fewer resources as well as individuals and families with diverse individual histories must be innovative and creative in meeting the needs of older people as well as those of all family members.
