Relationship quality and functional limitations among older adults with cardiovascular disease in the United States of America

A tale of two marital stressors: Comparing proinflammatory responses to partner distress and marital conflict

Marital quality shares ties to inflammatory conditions like cardiovascular disease and diabetes. For decades, research has focused on marital conflict as a primary mechanism given its potential to trigger inflammatory responses. However, longitudinal evidence suggests that marital conflict declines over time, and little attention has been paid to the inflammatory aftermath of other types of marital exchanges. A spouse's emotional distress is an important but overlooked marital context, as partners are exposed to each other's upsetting emotions throughout adulthood. To directly compare reactivity in proinflammatory gene expression to these two marital stressors and to examine differences by age and marital satisfaction, 203 community adults ages 25-90 (N = 102 couples) provided blood samples and rated their negative mood before and after they 1) watched their partner relive an upsetting personal memory and, in a separate visit 1-2 weeks later, 2) discussed a conflictual topic in their relationship. Controlling for age, sex, race/ethnicity, BMI, alcohol use, smoking, and comorbidities, increases in proinflammatory gene expression were significantly larger after the partner's upsetting disclosure than after marital conflict (B = 0.073, SE = 0.031, p = .018). This pattern paralleled emotional reactivity to the tasks, wherein negative mood rose more in response to the partner's disclosure than to marital conflict (B = 4.305, SE = 1.468, p = .004). In sum, proinflammatory and mood reactivity to spousal distress exceeded reactivity to marital conflict, a well-established marital stressor. Findings reveal spousal distress as a novel mechanism that may link marriage to inflammation-related diseases, and even pose risks for both happy and unhappy couples across adulthood.

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.

What's love got to do with it? Relationship quality appraisals and quality of life in couples facing cardiovascular disease

Objective

Changes in couples' relationship quality are common post-cardiac event but it is unclear how relationship quality is linked to patients' and spouses' quality of life (QoL). The purpose of the present study was to examine the association between relationship quality on QoL in patient-spouse dyads within six months of a cardiac event.

Methods

Participants (N = 181 dyads; 25.9% female patients), recruited from a large cardiac hospital, completed validated questionnaires measuring demographic, relationship (Dyadic Adjustment Scale; DAS) and QoL variables (Heart-QoL & Quality of life of Cardiac Spouses Questionnaire). An Actor-Partner Interdependence Model was used to investigate actor (i.e. responses influencing their own outcome) and partner effects (responses influencing their partner's outcome) of relationship quality and QoL.

Results

Patients' and spouses' perceptions of relationship quality were in the satisfied range (DAS > 108; 65% of sample) and, as expected, patients reported lower general physical QoL than did their spouse (t(180) = -10.635, p < .001). Patient and spouse relationship quality appraisals were positively associated with their own physical (patient β = .25; spouse β = .05) and emotional/social (patient β = .21; spouse β = .04) QoL. No partner effects were identified.

Conclusion

High quality relationship appraisals appear to matter for patients' and spouses' QoL after the onset of CVD.

Marital Quality and Salivary Telomere Length Among Older Men and Women in the United States

Objective: The link between marital quality and cellular aging remains underexplored. This study examined how both positive and negative marital quality were associated with salivary telomere length among partnered adults in the United States over the age of 50°years. Methods: Data were from the 2008 Health and Retirement Study (N = 3203). Ordinary least squares regression was used to estimate the link between marital quality and telomere length. Results: While neither positive nor negative marital quality was significantly associated with telomere length among older women, positive and negative marital quality had an interacting effect on telomere length among men. Specifically, when negative marital quality was low, higher positive marital quality was associated with shorter telomere length, whereas when negative marital quality was high, higher positive marital quality was associated with longer telomere length. Discussion: The findings speak to the complex nature of intimate partnerships and the implications of these partnerships for cellular aging processes.
