Reactivity to marital conflict has long been considered a critical mechanism linking marriage to health and well-being. Yet, developmental theories suggest conflict may subside with age. To compare mood and cardiovascular responses to two novel contexts—both partners’ upsetting personal experiences—with marital conflict reactivity, 107 couples ages...
Article
Full-text available
Marital conflict poses health risks that intensify as couples grow older. Dyadic stress theories suggest spouses’ marital satisfaction and communication patterns alter cardiovascular function, a key pathway from troubled relationships to poor health. Despite these risks, older spouses are more likely to have a strong couple identity where they thin...
Article
Objective: Conflict poses multiple relational and health risks. Dyadic stress theories suggest satisfaction and communication alter cardiovascular and autonomic function, key pathways from troubled relationships to poor health. However, "we-talk," a positive communication pattern, can strengthen relationships and promote health. We examined how ea...
Article
Background Dyadic stress theories and research suggest that couples’ negative communication patterns threaten immune and emotional health, leaving partners vulnerable to illness. Spouses’ relationship perceptions can also color how they see and react to marital discussions. To identify pathways linking distressed marriages to poor health, this stud...
Article
Background Inflammation can have social consequences, which may be relevant to inflammation’s link with depression. The current study tests whether a typhoid vaccine increases feelings of social disconnection and avoidance behavior. Method In two full-day visits at least three weeks apart, 172 postmenopausal breast cancer survivors (Stage I-IIIA)...

Purpose To investigate breast cancer survivors’ inflammatory responses to typhoid vaccine as a window into their innate immune response to novel pathogens. Methods This double-blind crossover trial randomized 158 breast cancer survivors to either the vaccine/saline placebo or the placebo/vaccine sequence. The relative contributions of age, cardior...
Article
In both animals and humans, inflammatory stimuli – especially infections and endotoxin injections – cause “sickness behaviors,” including lethargy, malaise, and low mood. An emerging line of research asserts that inflammation may provoke present-focused decision making and impulsivity. The current article assesses that claim in the context of the b...
Article
Background Breast cancer survivors are prone to weakened gut barriers, allowing bacteria to migrate into the blood stream. Gut permeability fuels inflammation, which, among survivors, can elevate risk for comorbid disease development, cancer recurrence, and a poor quality of life; however, survivors’ satisfying relationships can provide health bene...
Article
Full-text available
The social-signal-transduction theory of depression asserts that people who experience ongoing interpersonal stressors and mount a greater inflammatory response to social stress are at higher risk for depression. The current study tested this theory in two adult samples. In Study 1, physically healthy adults ( N = 76) who reported more frequent int...
Conference Paper
Full-text available
Marital quality shares ties to inflammation-related conditions like cardiovascular disease and diabetes. Lab-based studies implicate hostility during marital conflict as a mechanism via inflammatory reactivity. However, developmental theories suggest that conflict declines with age. Spousal distress is an important but overlooked context for aging...
Conference Paper
Full-text available
Aging theories posit that older adults maximize their well-being by regulating their emotions and investing in their closest relationships. Most research has examined these mechanisms using study confederates rather than close dyads. The existing work on couples has focused on marital conflict; none has examined responses to the spouse’s emotional...

PurposeLeptin influences inflammation and tumor growth and leptin signaling is often dysregulated among obese breast cancer survivors. This leads to a lack of satiety and, ultimately, risk for further weight gain. Breast cancer survivors also experience high rates of depression and anxiety, which are linked to leptin production. This study examined...
Article
According to extensive evidence, we-talk—couples’ use of first-person, plural pronouns—predicts better relationship quality and well-being. However, prior work has not distinguished we-talk by its context, which varies widely across studies. Also, little is known about we-talk’s consistency over time. To assess the stability and correlates of we-ta...
Article
Background Breast cancer survivors face a number of physical health threats including cardiovascular disease, the leading cause of death among breast cancer survivors. Low heart rate variability (HRV) represents one well-established risk factor for poor cardiovascular health. Among physically healthy adults and breast cancer survivors, distress dis...

Full-text available
Social-emotional well-being is said to improve with age, but evidence for age differences in couples’ behavior and emotions—studied primarily during marital conflict—has been mixed. Characteristics of jointly told relationship stories predict marital quality among newlyweds and long-married couples alike, yet younger and older couples’ accounts hav...
Conference Paper
Full-text available
According to socioemotional aging theories, people better regulate their emotions in older age by reframing stressors and focusing on the positive aspects of difficult experiences. However, empirical results have been mixed. To address this gap, we examined age differences in the language use and cardiovascular reactivity of 188 adults (mean age=56...
Article
Background The Center for Disease Control (CDC) recently named childhood abuse histories as a public health risk. Clear links between abuse histories and inflammation exist. However, it remains unknown how abuse histories impact inflammatory trajectories throughout adulthood. Accordingly, this study assessed inflammatory trajectories across three v...
Article
Full-text available
Background and Objectives Individuals with social anxiety disorder show pronounced perceptual biases in social contexts, such as being hypervigilant to threat and discounting positive social cues. Parasympathetic activity influences responses to the social environment and may underlie these biases. This study examined the associations among social...
Article
Objective Cross-sectional data have linked gut barrier abnormalities and endotoxemia with depression, even among those without gastrointestinal symptoms. This study examined longitudinal associations between endotoxemia markers and depressive symptoms, as well as the role of inflammation in this relationship. Design At three annual visits, 315 wom...

Article
The Western diet, characterized by high intake of saturated fat, sugar, and salt, is associated with elevated inflammation and chronic disease risk. Few studies have investigated molecular mechanisms linking diet and inflammation; however, a small number of randomized controlled trials suggest that consuming an anti-inflammatory diet (i.e., a prima...
Article
Objectives: Cancer contributes to adverse changes in body composition that may increase risk of cardiometabolic diseases. Skeletal muscle is a main driver of cardiometabolic health. We hypothesize that higher intake of long chain omega-3 polyunsaturated fatty acids (LCn3PUFAs) is associated with muscle health. This study evaluates whether LCn3PUFA...
Conference Paper
Background: Growing evidence implicates intestinal permeability as a source of inflammation. Depression promotes inflammation, which can erode the gut barrier – a top-down pathway. In turn, greater intestinal permeability (i.e., leaky gut) provokes inflammation, thereby heightening risk for depression – a bottom-up pathway. Methods: The current st...
Article
Background Prior to treatment, breast cancer patients are less physically fit compared to peers; during cancer treatment, their fitness typically declines. Depressive symptoms are associated with reduced activity up to 5 years post-treatment, but research has not identified mechanisms linking depression and lower activity. The current study assesse...
Conference Paper
Many breast cancer survivors experience improvements in depression, fatigue, and inflammation after cancer treatment, but a subset of survivors experience persistent symptoms years after treatment ends. Prior cross-sectional research indicates that childhood adversity predicts elevated symptoms one year following cancer treatment; however, studies...
Conference Paper
Lonely people’s heightened risks for chronic health conditions and early mortality may emerge in part through cellular aging. Lonelier people have more severe responses to acute stress, increasing their risk for herpesvirus reactivation, a possible path to shorter telomeres. Lower parasympathetic activity may modulate this risk. To examine the asso...
Article
Social-emotional aging theories suggest that older adults maintain well-being and health in part by avoiding interpersonal stressors; yet, most marital research has examined age differences during conflict. Alternatively, marital support is likely relevant for couples of all ages. To address differences in support-health associations by age and mar...
Article
Background and objectives: Stress can trigger physical pain and disturb sleep. Whether dementia family caregivers experience heightened pain is unknown. Cycles of unwanted thoughts about caregiving stressors and avoidance of these thoughts-that is, caregiving-related distress-may exacerbate both pain and sleep disturbances, and genetic susceptibil...
Article
Couples influence each other's mental and physical health. This review focuses on how couples' relationships, the partners' individual and joint vulnerabilities, and their health behaviors influence health through changes in the gut microbiota, metabolism, and immune function.

Article
Background Lonely people’s heightened risks for chronic health conditions and early mortality may emerge in part through cellular aging. Lonelier people have more severe sympathetic responses to acute stress, increasing their risk for herpesvirus reactivation, a possible path to shorter telomeres. Parasympathetic function may modulate this risk. P...
Article
Background: Marital distress and depression work in tandem to escalate risks for inflammation-related disorders. Translocation of bacterial endotoxin (lipopolysaccharide, LPS) from the gut microbiota to blood circulation stimulates systemic inflammatory responses. Methods: To investigate increased gut permeability (a "leaky gut") as one potentia...
Article
Hostile conflict in marriage can increase risks for disease and mortality. Physiological synchrony between partners-e.g., the linkage between their autonomic fluctuations-appears to capture engagement, or an inability to disengage from an exchange, and thus may amplify the health risks of noxious interactions such as marital conflict. Prior work ha...
Poster
Cancer-related distress is common among breast cancer survivors prior to treatment and is associated with adverse health effects. Moreover, many survivors continue to experience distress after treatment ends, and the impact of prolonged cancer-related distress on health is unknown. The aim of the current study was to investigate the effects of canc...
Article
An unhappy marriage increases disease and mortality risks. Discordant couples exhibit stronger links to their partner’s autonomic fluctuations–that is, stronger covariation–than do satisfied couples, but whether this physiological signature plays a role in marriage’s health effects is unknown. To examine associations between couples’ heart rate var...
Article
Dual-process models of health behavior posit that implicit and explicit attitudes independently drive healthy behaviors. Prior evidence indicates that implicit attitudes may be related to weekly physical activity (PA) levels, but the extent to which self-regulation attenuates this link remains unknown. This study examined the associations between i...
Article
Thoughts and emotions following marital conflict have received little attention but almost certainly contribute to marriage’s long-term health effects. Consistent with emotion theories of aging, we expected the effects of post-conflict thoughts on important neuroendocrine and immune outcomes, cortisol levels and full-thickness wound healing, to dif...
Article
This review highlights recent advances in research addressing intimate partner relationships and health. Consideration of the strong mutual influences that the members of a couple have on each other's mental and physical health trajectories provides a new way to view the health implications of couples' convergence or interdependence; marital closen...

Scope: Supplementation with linoleic acid (LA; 18:2Ω6)-rich oils increases lean mass and decreases trunk adipose mass in people. Erythrocyte fatty acids reflect the dietary pattern of fatty acid intake and endogenous metabolism of fatty acids. The aim of this study is to determine the relationship of erythrocyte LA, with aspects of body compositio...
Article
Women become depressed more frequently than men, a consistent pattern across cultures. Inflammation plays a key role in initiating depression among a subset of individuals, and depression also has inflammatory consequences. Notably, women experience higher levels of inflammation and greater autoimmune disease risk compared to men. In the current re...
Article
Depression and inflammation fuel one another. Inflammation plays a key role in depression's pathogenesis for a subset of depressed individuals; depression also primes larger cytokine responses to stressors and pathogens that do not appear to habituate. Accordingly, treatment decisions may be informed by attention to questions of how (pathways) and...
