Linking Marital Support to Aging-Related Biomarkers: Both Age and Marital Quality Matter

Psychosocial and biological pathways to aging : The role(s) of the behavioral and social sciences in geroscience

While the biological hallmarks of aging are widely recognized as fundamental mechanisms of biological aging, more recently, there have been calls within geroscience to understand the aging process more comprehensively by adding a perspective of the social hallmarks of aging. Social and behavioral factors, such as socioeconomic status, life events or behavior and beliefs can alter the aging process per se and act in complex interactions with biological pathways. In addition, underlying biological pathways have been proposed for various psychosocial concepts, such as views on age and relationship quality. The aim of the present article is to provide narrative insights into theoretical and empirical developments between social and behavioral gerontology and geroscience or biogerontology. This article focuses on the potential of an interdisciplinary aging research but it also sets out the critical perspective that social gerontology provides.

Psychoneuroimmunology in multiple myeloma and autologous hematopoietic stem cell transplant: Opportunities for research among patients and caregivers

Multiple myeloma (MM) is an incurable cancer and is the leading indication for autologous hematopoietic stem cell transplantation (HSCT). To be eligible for HSCT, a patient must have a caregiver, as caregivers play a central role in HSCT preparation and recovery. MM patients remain on treatment indefinitely, and thus patients and their caregivers face long-term challenges including the intensity of HSCT and perpetual therapy after transplant. Importantly, both patients and their caregivers show heightened depressive and anxiety symptoms, with dyadic correspondence evidenced and caregivers' distress often exceeding that of patients. An extensive psychoneuroimmunology (PNI) literature links distress with health via immune and neuroendocrine dysregulation as well as biological aging. However, data on PNI in the context of multiple myeloma - in patients or caregivers - are remarkably limited. Distress in MM patients has been associated with poorer outcomes including higher inflammation, greater one year post-HSCT hospital readmissions, and worse overall survival. Further, anxiety and depression are linked to biological aging and may contribute to the poor long-term health of both patients and caregivers. Because MM generally affects older adults, individual differences in biological aging may represent an important modifier of MM biology and HSCT treatment outcomes. There are a number of clinical scenarios in which biologically younger people could be prescribed more intensive therapies, with potential for greater benefit, by using a personalized cancer therapy approach based on the quantification of physiologic reserve. Further, despite considerable psychological demands, the effects of distress on health among MM caregivers is largely unexamined. Within this context, the current critical review highlights gaps in knowledge at the intersection of HSCT, inflammation, and biological aging in the context of MM. Research in this area hold promise for opportunities for novel and impactful psychoneuroimmunology (PNI) research to enhance health outcomes, quality of life, and longevity among both MM patients and their caregivers.

Intimate Partner Violence and Inflammaging: Conflict Tactics Predict Inflammation Among Middle-Aged and Older Adults

OBJECTIVE

In long-term relationships, conflict is inevitable, but physical and psychological aggression is not. Intimate partner violence is a known risk factor for age-related disease onset, and inflammation likely links the two. This study explores relationships between frequency of constructive (i.e., negotiation) and destructive (i.e., aggression) conflict tactics with inflammation in both younger and older adulthood. Based on the theory of inflammaging, the study investigates whether these associations were stronger in mid-to-late adulthood.

METHODS

At one visit, 214 participants in long-term romantic relationships had their blood drawn to assess six inflammatory markers (interleukin-6 [IL-6], tumor necrosis factor α [TNF-α], C-reactive protein, serum amyloid A (SAA), soluble intercellular adhesion molecule (sICAM), soluble vascular cell adhesion molecule) and reported frequency of destructive and constructive conflict tactics with their partner in the past year on the Revised Conflict Tactics Scale short form.

RESULTS

Age interacted with number of destructive conflicts per year to predict serum IL-6 ( F (1,200) = 5.3, p = .022), TNF-α ( F (1,180) = 4.2, p = .043), sICAM ( F (1,193) = 7.0, p = .008), and marginally SAA ( F (1,199) = 3.7, p = .055), such that middle-aged and older adults who reported more destructive tactics had higher inflammation. Also, the relationship between constructive conflict frequency and TNF-α also depended on age ( F (1,177) = 4.9, p = .029), in that older adults who reported a greater number of constructive tactics had lower TNF-α.

CONCLUSION

Couples' conflict tactics may influence levels of inflammation and therefore aging rate in mid-to-late life. Middle-aged and older adults may disproportionately benefit from a healthy partnership and suffer from an unhealthy partnership.

Could long-term dialysis vintage and abnormal calcium, phosphorus and iPTH control accelerate aging among the maintenance hemodialysis population?

OBJECTIVE

Aging is a complex process of physiological dysregulation of the body system and is common in hemodialysis patients. However, limited studies have investigated the links between dialysis vintage, calcium, phosphorus, and iPTH control and aging. The purpose of the current study was to examine these associations.

METHODS

During 2020, a cross-sectional study was conducted in 3025 hemodialysis patients from 27 centers in Anhui Province, China. Biological age was calculated by a formula using chronological age and clinical indicators. The absence of the target range for serum phosphorus (0.87-1.45 mmol/L), corrected calcium (2.1-2.5 mmol/L) and iPTH (130-585 pg/mL) were identified as abnormal calcium, phosphorus, and iPTH control.

RESULTS

A total of 1131 hemodialysis patients were included, 59.2% of whom were males (669/1131). The mean (standard deviation) of actual age and biological age were 56.07 (12.79) years and 66.94 (25.88), respectively. The median of dialysis vintage was 4.3 years. After adjusting for the confounders, linear regression models showed patients with abnormal calcium, phosphorus, and iPTH control and on hemodialysis for less than 4.3 years (B = 0.211, p = .002) or on hemodialysis for 4.3 years or more (B = 0.302, p < .001), patients with normal calcium, phosphorus, and iPTH control and on hemodialysis for 4.3 years or more (B = 0.087, p = .013) had a higher biological age.

CONCLUSION

Our findings support the hypothesis that long-term hemodialysis and abnormal calcium, phosphorus, and iPTH control may accelerate aging in the hemodialysis population. Further studies are warrant to verify the significance of maintaining normal calcium-phosphorus metabolism in aging.

The Story of Us: Older and Younger Couples' Language Use and Emotional Responses to Jointly Told Relationship Narratives

OBJECTIVES

Social-emotional well-being is said to improve over adulthood, and studies of couples' age differences have focused primarily on marital conflict. The way couples discuss their relationship story predicts marital quality among newlyweds and long-married couples alike, yet older and younger couples' accounts have never been compared. The current study examined age differences in couples' use of I/we-talk, emotion words, and immediacy (i.e., an urgent and unresolved style) during a relationship history discussion and their subsequent mood reactivity and appraisals.

METHOD

Married couples (N = 186 individuals within 93 couples, aged 22-77) recounted the story of their relationship then rated the discussion and their negative mood. Mediation models assessed the 3 linguistic features as parallel dyadic mediators linking couple age to negative mood responses and appraisals, controlling for global marital satisfaction, and baseline negative mood. Secondary analyses examined partners' concordance in language use.

RESULTS

Compared with younger couples, older couples used more positive than negative words and less immediacy which, in turn, was associated with husbands' and wives' less negative mood and more positive appraisals, only among husbands. Partners in older couples used more similar I/we-talk and emotional language, but these were unrelated to mood or appraisals.

DISCUSSION

This study extends our understanding of how marital interactions differ by age in the understudied context of relationship history discussions, which may grow increasingly important for couples' well-being with older age. Findings broadly align with social-emotional aging theories and uncover novel linguistic features relevant to the age-related emotional benefits of joint reminiscing.

Is Marital Quality Related to Physical Activity Across the Life Course for Men and Women?

OBJECTIVES

Although physical activity is linked to multiple health outcomes, a majority of Americans do not meet physical activity guidelines, often with precipitous declines among older adults. Marital quality is a less-explored, but important, factor that may influence physical activity, as spouses often influence each other's health behaviors.

METHODS

We use nationally representative panel data to investigate whether positive and negative dimensions of marital quality influence physical activity, and whether age and gender moderate these relationships.

RESULTS

We find that both marital support and strain are related to higher odds of more frequent active exercise and walking, pointing to the complex influence of marital quality. Marital support became increasingly important to higher levels of walking frequency as men aged.

DISCUSSION

This study provides new information on the ways in which both positive and negative dimensions of marital quality may contribute to trajectories of physical activity across the life course.

How Families Make Their Way Into Your Heart: Exploring the Associations Between Daily Experiences Involving Family Members and Cardiovascular Health

BACKGROUND

Cardiovascular disease is a critical public health issue and a growing body of literature on relationships and health point to individuals' interactions and involvement with family members as significant correlates of cardiovascular outcomes. However, less is known about the implications of daily encounters with family members on cardiovascular health outcomes and how the associations vary across adulthood.

PURPOSE

The aims of this study were to examine the associations of positive and negative daily experiences with family members with comprehensive measures of cardiovascular health and to further explore how age moderates these associations.

METHODS

This study used data from the Midlife in the United States (MIDUS) II and MIDUS Refresher. The sample was composed of respondents who participated in two subprojects of MIDUS, namely the National Study of Daily Experiences (NSDE) and Biomarker Project (N = 1,312). Indices of cardiovascular health included inflammatory markers, autonomic functioning, and Life's Simple 7 scores.

RESULTS

Results showed that the associations between daily family experiences and cardiovascular outcomes differed by age. Having more daily negative experiences with family members was associated with better cardiovascular health outcomes among young adults and worse cardiovascular outcomes among older adults. Having more daily positive experiences was also associated with lower heart rate variability for older adults.

CONCLUSIONS

Results revealed that contrary to the general assumption that negative experiences have health-damaging effects, frequent involvement with family members in daily life, even negative ones, may be indicative of active engagement in life that could be health promoting for younger adults.

Optimism, pessimism and support in older couples: A longitudinal study

OBJECTIVES

Optimism is linked to varied advantageous outcomes, ranging from improved health to better relationships, while pessimism is linked to reduced well-being. Relatively little is known about how optimism and pessimism may work together to shape the perception of support within marital relationships, and whether perceived support can affect couple-members' optimism and pessimism.

METHOD

We used three waves of a nationally representative sample of older couples (N = 1681 couples), spanning a period of eight years. Partners reported perceived support, optimism, and pessimism in each wave. We used a random-intercept cross-lagged panel model (RI-CLPM) to test within- and between-person effects.

RESULTS

At the within-person level, husbands', but not wife's, future expectations were associated with partners' perceived marital support; increases in husbands' pessimism on a given wave were related to decreases in husbands' perceived marital support at the next wave, and vice versa (i.e., actor effect). Within the same wave, increases in husbands' pessimism were associated with wives' decreased perceived marital support. At the between-person level, both partners' optimism and pessimism were associated with marital support.

DISCUSSION

Findings suggest that changes in husbands' levels of pessimism propel marital support experiences of both partners. At the methodological level, results highlight the importance of examining interpersonal processes at both the within- and between-levels of analyses, as they may yield divergent patterns.

The health consequences of stress in couples: A review and new integrated Dyadic Biobehavioral Stress Model

Despite marriage's health benefits, all couples experience stress that can increase morbidity and mortality risks. Marital stress can alter endocrine, cardiovascular, and immune function-key pathways from troubled relationships to poor health. This review discusses how partners "get under each other's skin" to influence psychological, behavioral, and biological health. Then, I offer a comprehensive Dyadic Biobehavioral Stress Model to build on this foundational work and inspire transdisciplinary research integrating psychoneuroimmunological and relational lenses. This conceptual and empirically driven model provides promising new directions to investigate mechanisms linking individuals' relationships behaviors to their own and their partners' health, with particular emphasis on biological pathways. These mechanisms may impact each partner's physical health outcomes, such as disease development, illness severity, and accelerated biological aging. Risk and protective factors across developmental stages and diverse contexts are also discussed to help explain how, and under what conditions, partners influence each other's health. Research applying this model can push the boundaries of our current understanding on dyadic stress its far-reaching health effects on self-report and biological markers across the lifespan.

Individual, relational, and developmental-contextual pathways linking marriage to health: Reply to Brazeau, Pfund, and Hill (2020)

Replies to comments made by H. Brazeau, G. N. Pfund, and P. L. Hill (see record 2019-81943-004) on the original article by J. K. Kiecolt-Glaser (see record 2018-62311-007). Brazeau, Pfund, and Hill's (2020) comment on Kiecolt-Glaser's (2018) "Marriage, Divorce, and the Immune System" review article provides a thoughtful application of attachment theory to the relationship-health link. In addition to an attachment perspective, we offer multiple moderating and mediating mechanisms through which marriage contributes to health. A brief overview of relationship stress and coping models, as well as the importance of couples' interdependence, is discussed. We provide specific individual, couple, and developmental-contextual factors through an interdependence lens that help explain the health costs and benefits of relationships.
