Effects of Pollution Burden on Neural Function During Implicit Emotion Regulation and Longitudinal Changes in Depressive Symptoms in Adolescents

BackgroundExposure to environmental pollutants early in life has been associated with increased prevalence and severity of depression in adolescents; however, the neurobiological mechanisms underlying this association are not well understood. In the current longitudinal study, we investigated whether pollution burden in early adolescence (9–13 years) was associated with altered brain activation and connectivity during implicit emotion regulation and changes in depressive symptoms across adolescence. MethodsOne hundred forty-five participants (n = 87 female; 9–13 years) provided residential addresses, from which we determined their relative pollution burden at the census tract level, and performed an implicit affective regulation task in the scanner. Participants also completed questionnaires assessing depressive symptoms at 3 time points, each approximately 2 years apart, from which we calculated within-person slopes of depressive symptoms. We conducted whole-brain activation and connectivity analyses to examine whether pollution burden was associated with alterations in brain function during implicit emotion regulation of positively and negatively valenced stimuli and how these effects were related to slopes of depressive symptoms across adolescence. ResultsGreater pollution burden was associated with greater bilateral medial prefrontal cortex activation and stronger bilateral medial prefrontal cortex connectivity with regions within the default mode network (e.g., temporoparietal junction, posterior cingulate cortex, precuneus) during implicit regulation of negative emotions, which was associated with greater increases in depressive symptoms across adolescence in those exposed to higher pollution burden. ConclusionsAdolescents living in communities characterized by greater pollution burden showed altered default mode network functioning during implicit regulation of negative emotions that was associated with increases in depressive symptoms across adolescence.

Dyadic profiles of couples' self-perceptions of aging: Implications for mental health.

The way older adults perceive their own aging processes influences their mental health, but we know little about how this occurs in a dyadic context, where spouses' perceptions and health are often intertwined. The present study sought to identify dyadic profiles of self-perceptions of aging (SPAs) in couples and examine how certain profiles are associated with each partner's mental health over time. A pooled sample of 3,850 heterosexual couples aged 50+ in the Health and Retirement Study (2012/2014) rated positive and negative SPAs and provided data on demographic characteristics, couple relationships, and health. We tracked these couples' depressive symptoms over 2 years (2014/2016). Latent profile analysis revealed five profiles of couples' SPAs: similarly positive (20%), similarly negative (6%), similarly average (38%), husband negative (20%), and wife negative (17%). Physical health and marital quality consistently differentiated couples in profile membership. Couples with similarly positive and similarly average SPAs reported the smallest increases in depressive symptoms over time, and couples with similarly negative SPAs fared worst in mental health. We observed interesting gender differences across profiles; husbands in the husband negative profile reported significantly greater increases in depressive symptoms than those in the wife negative profile. Yet, wives in these two profiles did not differ in their depressive symptoms over time, and they reported worse mental health than wives in the similarly positive and similarly average profiles. This study adds to the emerging literature that advocates for an interpersonal approach to SPAs and reveals risk and resilience in couples as they age together.

3 The Relationship Between Depression, Anxiety, and Autonomic Dysfunction in de novo Parkinson’s Disease Patients Over Time

Objective:Autonomic dysfunction is an important non-motor symptom of Parkinson’s disease (PD), with point prevalence estimates of approximately 50-70%. Common presentations include cardiovascular dysregulation, gastrointestinal dysfunction, impaired thermoregulation, and sexual dysfunction. In the present study, we sought to examine whether autonomic symptoms would predict trajectories of change in depression and anxiety over a 5-year period in newly diagnosed individuals with PD. Given that alterations in autonomic nervous system functioning (e.g., reduced heart rate variability, lower autonomic arousal) are frequently observed in individuals who have anxiety and depression, as well as the negative influence these symptoms can have on quality of life/functioning, we predicted that greater autonomic symptoms would be related to increased mood symptoms over time.Participants and Methods:Participants included 414 individuals from the Parkinson’s Progression Markers Initiative, a prospective study of newly diagnosed and untreated individuals with PD. The PD participants (mean age=61.6+9.7, mean education=15.6+3.0, 92.5% non-Hispanic White) were followed annually for up to five years. Self-reported autonomic symptoms were measured using the Scales for Outcomes in Parkinson’s Disease-Autonomic Dysfunction (SCOPA-AUT), which consists of a total score and 6 subdomain scores (gastrointestinal, urinary, cardiovascular, thermoregulatory, pupillomotor, sexual). Mood measures included the Geriatric Depression Scale (GDS) and State-Trait Anxiety Inventory (STAI). Motor severity was assessed using the Unified Parkinson’s Disease Rating Scale (UPDRS) Part III. Bootstrapped linear regressions were performed to evaluate the relationship between autonomic symptoms (subdomains) and mood using data from the last visit (year 5). For longitudinal analyses, bootstrapped multilevel modeling was used to examine a) changes in SCOPA-AUT total over time (unconditional growth model only) and b) the relationship between mood and SCOPA-AUT total score over time, controlling for age/sex and motor severity.Results:Autonomic symptoms explained 28.2% of the total variance in trait anxiety, with unique predictors of gastrointestinal (/3=.266, p<.001) and thermoregulatory (ß=.202, p=.004) symptoms. For depression, autonomic symptoms explained 27.9% of the total variance, with unique predictors of gastrointestinal (ß=.225, p=.012), thermoregulatory (ß=.178, p=.013), and cardiovascular (ß=.154, p=.012) symptoms. There was a gradual linear increase in total autonomic symptoms over time (b=0.86, p<.001). Greater total autonomic symptoms were associated with higher average trait anxiety (b=0.54, p<.001), slightly greater increase in trait anxiety over time (b=0.04, p<.05), and occasion-to-occasion fluctuations in trait anxiety (b=0.24, p<.001). Similarly, increased total autonomic symptoms were associated with higher average depressive symptoms (b=0.14, p<.001), minimally greater increase in depressive symptoms over time (b=0.01, p<.05), and occasion-to-occasion fluctuations in depressive symptoms (b=0.08, p<.001). Motor severity did not explain individual differences or trajectories of change in depression or trait anxiety.Conclusions:Autonomic symptoms, particularly gastrointestinal, cardiovascular, and thermoregulatory dysfunction, were related to increased mood symptoms in PD patients and predicted increases in depression/anxiety over time. Our findings do not distinguish between two theoretical possibilities - whether autonomic symptoms lead to depression/anxiety versus involvement of co-occurring neural systems underlying both. Regardless, our study highlights the importance of treating autonomic dysfunction in early PD, and future work should incorporate additional measures of autonomic dysfunction (e.g., physiological probes).

Social jetlag and trajectories of mood symptoms and reward responsiveness in individuals at low-risk, high-risk, and with bipolar spectrum disorders: An ecological momentary assessment study

A specific type of sleep disruption, social jetlag, involves an incongruence of sleep time between weekends and weekdays. This study investigated relationships between social jetlag and mood symptom lability and trajectories of daily reward responsiveness and mood symptoms. Participants (N = 130) from three groups (moderate reward sensitivity, high reward sensitivity, and high reward sensitivity with a diagnosed bipolar spectrum disorder [BSD]) were recruited from an ongoing longitudinal study based on their self-reported reward sensitivity and a diagnostic interview. For this study, they completed 20 days of ecological momentary assessment (EMA) of reward responsiveness and mood symptoms and a daily sleep diary. Social jetlag was significantly associated with differences in trajectories of depressive symptoms between groups. Specifically, greater social jetlag was associated with a greater increase in depressive symptoms over the 20 days for participants in the high reward sensitivity and BSD groups compared to the moderate reward sensitivity group. Social jetlag also was significantly associated with depressive symptom lability during the EMA period, but this finding was reduced to a trend toward significance when controlling for self-reported sleep duration. The study adds to the literature with methodological strengths including the EMA design and assessment of symptom and reward responsiveness trajectories.

Title: Risks and Benefits of Pre-delivery Taper In Pregnant Women Taking Antidepressants.

Serotonin reuptake inhibitors are commonly used for treatment of mental health problems in pregnancy but may cause neonatal adaptation syndrome. It is unknown whether reduction or discontinuation of medication prior to delivery may mitigate this effect. We present a case series of 38 women who either tapered their medication prior to delivery or maintained or increased their dose. Greater reductions in maternal antidepressant dose just prior to delivery were associated with fewer admissions to the neonatal intensive care unit (NICU) for infants. There was a slightly greater increase in depressive symptoms across delivery for women who tapered, which was not statistically significant. NICU admissions may be less frequent among neonates whose mothers tapered their medication prior to delivery. Large prospective randomized trials are needed to further study this practice.

Changes and predictors of maternal depressive and anxiety symptoms during the COVID-19 pandemic.

Longitudinal changes in maternal depressive and anxiety symptoms and predictors of symptom variation among a group of middle-to-upper income Canadian women (n = 2152) were examined prior to the pandemic (2017-2019) and at three pandemic timepoints (May-July 2020, March-April 2021, November-December 2021). Mean maternal depression and anxiety scores were elevated throughout the pandemic. Pre-pandemic depressive symptoms were associated with greater increases in depressive symptoms. Coping and relationship quality were protective factors. Supporting the development of coping strategies may mitigate mental health concerns among mothers.

Physical activity mediates the effect of education on mental health trajectories in older age

ObjectiveWhy people with lower levels of educational attainment have poorer mental health than people with higher levels can partly be explained by financial circumstances. However, whether behavioral factors can further explain this association remains unclear. Here, we examined the extent to which physical activity mediates the effect of education on mental health trajectories in later life. MethodsData from 54,818 adults 50 years of age or older (55 % women) included in the Survey of Health, Aging and Retirement in Europe (SHARE) were analyzed using longitudinal mediation and growth curve models to estimate the mediating role of physical activity (baseline and change) in the association between education and mental health trajectories. Education and physical activity were self-reported. Mental health was derived from depressive symptoms and well-being, which were measured by validated scales. ResultsLower education was associated with lower levels and steeper declines in physical activity over time, which predicted greater increases in depressive symptoms and greater decreases in well-being. In other words, education affected mental health through both levels and trajectories of physical activity. Physical activity explained 26.8 % of the variance in depressive symptoms and 24.4 % in well-being, controlling for the socioeconomic path (i.e., wealth and occupation). ConclusionsThese results suggest that physical activity is an important factor in explaining the association between low educational attainment and poor mental health trajectories in adults aged 50 years and older.

Directional associations between cannabis use and depression from late adolescence to young adulthood: the role of adverse childhood experiences.

Although the co-occurrence of cannabis and depression is well established, less is known about the temporal sequence of cannabis use and depression. The present study had three main aims: to test a symptom-driven pathway in which depression may drive increases in cannabis use, to test a substance-induced pathway in which cannabis use may drive increases in depression and to assess a shared vulnerability model assessing associations between individuals who have (and have not) experienced adverse childhood experiences (ACEs). Data are from an ongoing, longitudinal, cohort study (n = 2234). Data were set up in an accelerated longitudinal design from age 17 to 24 years. Initial sample was recruited from Southern California, USA. The majority of participants still live in Southern California. On average, participants were aged 18 years at wave 8, with more than half identifying as female (54.3%; n = 1350). Most participants identified as Hispanic (1127; 45.4%), followed by non-Hispanic white (510; 20.5%), Asian (503; 20.2%), multi-racial/other (284; 11.4%) and non-Hispanic black (60; 2.2%). Primary outcomes were past-month days of cannabis use and depression symptoms [patient health questionnaire (PHQ)-8]. The Adverse Childhood Experiences scale was used as our main grouping measure. In the full sample, we showed that prior levels of depression symptoms were associated with a decrease in cannabis use [opposite to the proposed symptom driven model; B = -0.33 (-0.58, -0.09)]. Dynamic coupling parameters noted individuals who evidenced greater increases in cannabis use between two prior ages reported greater increases in depressive symptoms between subsequent ages [support for a substance-induced pathway; B = 0.53 (0.18, 0.89)]. Similar to the overall sample, for those who had not experienced ACEs, as cannabis use increased we saw a steady increase in depression [support for a substance induced pathway; B = 0.14 (0.04, 0.29)]. However, for those who experienced ACEs, as cannabis use increased we saw a consistent decrease in depression [opposite to the proposed substance-induced pathway; B = -0.18 (-0.28, -0.08)]. There is mixed support for both symptom-driven and substance-induced pathways between cannabis use and depression.

TURNOVER AND DEPRESSIVE SYMPTOMS AMONG MEXICAN AMERICAN CAREGIVERS OF PERSONS LIVING WITH DEMENTIA

Abstract This study explored the role of caregiver background, stressors, and resources for Mexican American caregiver turnover and depressive symptoms. Using two waves of the Hispanic Established Epidemiologic Study of the Elderly (H-EPESE, 2010/2011-2016 N=333) Caregiver Supplement and informed by the sociocultural caregiver stress process model, we estimate logistic and OLS regressions of change in dementia and change in caregiver over five years. Neuropsychiatric expressions were significantly associated with caregiver turnover. Adult children and grandchildren caregivers were more likely to experience caregiver turnover than spouses. While depressive symptoms were relatively low at both waves, there was a greater increase in depressive symptoms occurred for caregivers who completed the interview in Spanish rather than English, which was partially explained by greater perceived stress at baseline. Findings demonstrate the need to provide dementia care supports for Mexican American caregivers, reduce stress for Spanish-speaking caregivers, and support Mexican American grandchildren who unexpectedly become caregivers.

MEXICAN AMERICAN CAREGIVER HEALTH AND TURNOVER: THE ROLE OF STRESSORS, RESOURCES, AND BACKGROUND FACTORS

Abstract The purpose of this study is to explore the role of caregiver background, stressors, and resources for Mexican American caregiver turnover and depressive symptoms. Using two waves of the Hispanic Established Epidemiologic Study of the Elderly Caregiver Supplement (H-EPESE CG, 2010/2011-2016 N=333) and informed by the sociocultural caregiver stress process model, we estimate logistic and OLS regressions of caregiver turnover and caregiver depressive symptoms over five years. Neuropsychiatric expressions of dementia were significantly associated with caregiver turnover and relative to caregivers who were adult children of the care recipient, grandchildren caregivers and other kin and non-kin caregivers were more likely to experience caregiver turnover. While depressive symptoms were relatively low at both waves, there was a greater increase in depressive symptoms for caregivers who completed the interview in Spanish, which was partially explained by lower caregiver resources (e.g., support from others). The findings demonstrate the need for dementia care supports for Mexican American caregivers, improving support systems for Spanish-speaking caregivers, and supporting Mexican American caregivers who may be entering the role unexpectedly (e.g., grandchildren or non-kin).

The relationship of adverse childhood experiences, hair cortisol, C-reactive protein, and polygenic susceptibility with older adults’ psychological distress during the COVID-19 pandemic

Adverse childhood experiences (ACEs) are linked to poorer mental health outcomes, and growing evidence implicates biological and genetic pathways from early adversity to psychopathology. However, little is known about the relationship of ACEs and their underlying biological and genetic mechanisms with older people’s mental health responses to the COVID-19 pandemic. We tested the associations of ACEs, hair cortisol, C-reactive protein (CRP), and polygenic scores (PGS) with depression, anxiety, and loneliness among older adults during the COVID-19 pandemic, accounting for the potential interplay of ACEs with biological and genetic risk markers. Data were drawn from the English Longitudinal Study of Ageing, a prospective cohort study of older adults living in England. Retrospective information on ACEs were collected in 2006/7, while CRP and hair cortisol were measured at wave 6 (2012/13). Psychological distress was assessed before the pandemic (2018–19) and at two COVID-19 assessments in 2020 (June-July and November-December). Associations were tested on 2050 participants using linear/logistic regression models adjusted for pre-pandemic outcome measures and mixed-effect models to assess changes before and during the pandemic. The results showed that ACEs were associated with higher levels of depression (OR = 2.55[95%CI:1.81,3.59]) anxiety (OR = 1.84[95%CI:1.13,3.01]), and loneliness (b = 0.28[95%CI:0.14,0.42]) during the pandemic. Hair cortisol was related to an increased risk of depression (OR = 1.15[95%CI:1.04,1.26]), and CRP was associated with greater loneliness scores (b = 0.16[95%CI:0.03,0.30]). The relationship between cortisol and psychological distress was larger among participants with ACEs (e.g., ORdepression = 1.07[95%CI:1.00,1.14]). Further, individuals with high CRP experienced greater increases in feelings of loneliness from before to during the pandemic, compared to those with lower CRP levels (interaction effect=0.23; 95%CI:0.1–0.37). Individuals with 2+ ACEs experienced greater increases in depressive symptoms compared to those with none (interaction effect=2.09; 95%CI:1.1–3.98). Higher levels of hair cortisol were also related to worse changes in depressive symptoms across timepoints (interaction effect=1.84;95%CI:1.41–2.41). These results highlight the lasting impact of biosocial vulnerabilities on older adults’ mental health responses to new environmental stressors. They also implicate biological mechanisms in the pathophysiology of later-life psychological distress.

History of childhood mistreatment and the psychological health consequences of COVID-19 for older adults

Objectives We examine the associations between childhood mistreatment (emotional abuse, physical abuse, sexual abuse, and emotional neglect) and older adults’ changes in depressive symptoms from before to during the COVID-19 pandemic (September 2018–June 2020). Methods Using a community-based sample of older adults in North Florida (N = 581), we used ordinary least-squares regression to estimate associations between childhood mistreatments and depressive symptoms in June 2020, controlling for baseline symptoms and demographic characteristics. Additional models tested whether emotion regulation and social support attenuated associations between childhood mistreatments and depressive symptoms. Results Older adults exposed to emotional neglect in childhood saw a greater increase in depressive symptoms than those who did not experience childhood mistreatment. Those reporting childhood physical abuse had higher baseline depressive symptoms, but they did not increase during the pandemic. These associations remained stable after controlling for emotion regulation and social support, coping resources thought to contribute to linkages between childhood mistreatment and psychological health in adulthood. Conclusion Childhood mistreatment might inform the psychological consequences of major stressors in later life. Thus, early life interventions for children experiencing mistreatment could be especially important for long-term psychological health outcomes and responses to major stressful events. Identifying older people with histories of childhood mistreatment could also help clinicians gauge patients’ risk of psychological decline during times such as the COVID-19 pandemic and tailor psychological health interventions.

Sex-specific vulnerability to depressive symptoms across adolescence and during the COVID-19 pandemic: The role of the cingulum bundle.

BackgroundFemales are at higher risk for developing depression during adolescence than are males, particularly during exposure to stressors like the COVID‐19 pandemic. Examining structural connections between brain regions involved in executive functioning may advance our understanding of sex biases in stress and depression. Here, we examined the role of the cingulum bundle in differentiating trajectories of depressive symptoms in males and females across adolescence and during the pandemic.MethodsIn a longitudinal study of 214 youth (121 females; ages 9–13 years at baseline), we examined whether fixel‐based properties of the cingulum bundle at baseline predict changes in females' and males' severity of depressive symptoms across four timepoints (4–7 years) in adolescence, including during the COVID‐19 pandemic. We also tested whether cingulum properties predict self‐reported resilience and stress during the pandemic.ResultsFemales had lower fiber density and cross‐section (FDC) of the cingulum than did males, a neural pattern that predicted greater increases in depressive symptoms, lower resilience, and higher stress during the COVID‐19 pandemic. Cingulum morphometry predicted changes in depressive trajectories in females, but not in males; specifically, females with lower FDC had significant increases in symptoms throughout adolescence, whereas females with higher cingulum FDC did not. Conversely, males had low, stable depressive symptoms throughout adolescence and higher resilience and lower stress during the pandemic compared to females. Higher cingulum FDC predicted higher resilience and lower stress in both sexes.ConclusionsIn adults, the cingulum has been implicated in sex differences in stress reactivity. We show that in adolescents, the cingulum reflects sex differences in reports of stress and resilience that might contribute to the increased risk of stress‐related mood disorders in females. Adolescent females might benefit from cognitive interventions that strengthen the structural properties of the cingulum and increase their perceived resilience during periods of adversity and disruption.

Levels of Depression and Anxiety Among Informal Caregivers During the COVID-19 Pandemic: A Study Based on the Canadian Longitudinal Study on Aging.

ObjectivesStudies on informal caregiving during the coronavirus disease 2019 (COVID-19) pandemic have mainly focused on subgroups of caregivers using cross-sectional or convenience samples, limiting the generalizability of findings. Conversely, this longitudinal study examines the effects of the pandemic and caregiving factors on depressive symptoms and anxiety over 9 months among informal caregivers in Canada.MethodsThis study uses data from the Baseline (2011–2015), Follow-up 1 (2015–2018), and COVID-19 Study Baseline survey (April to May 2020) and Exit surveys (September to December 2020) of the Canadian Longitudinal Study on Aging (CLSA). A total of 14,118 CLSA participants who were caregivers at Follow-up 1 and participated in the COVID-19 studies were selected. Linear mixed models were used to examine the effect of sex of caregiver, changes in caregiving (increase in caregiving hours and inability to care), and location of care (same household, another household, and health care institution) on depressive symptoms and anxiety from COVID-19 studies Baseline to Exit surveys (about 6–7 months apart).ResultsInformal caregivers reported more frequent depressive symptoms from the COVID-19 Baseline to Exit surveys, but not anxiety. Female caregivers reported greater depressive symptoms and anxiety, and male caregivers exhibited a greater increase in depressive symptoms and anxiety over time. More caregiving hours and inability to provide care were significantly positively associated with depressive symptoms and anxiety. Also, in-home caregivers reported more depressive symptoms and anxiety than those who cared for someone in health care institution, and more anxiety than those who cared for some in another household.DiscussionThe findings shed light on the change in mental health among informal caregivers during the outset of the pandemic. The demonstrated associations between studied variables and mental health among informal caregivers provide empirical evidence for intervention programs aiming to support caregivers, particularly those who are female, and providing intensive care at home.

Trends in Depressive Symptoms and Associated Factors During Residency, 2007 to 2019 : A Repeated Annual Cohort Study.

Efforts to address the high depression rates among training physicians have been implemented at various levels of the U.S. medical education system. The cumulative effect of these efforts is unknown. To assess how the increase in depressive symptoms with residency has shifted over time and to identify parallel trends in factors that have previously been associated with resident physician depression. Repeated annual cohort study. U.S. health care organizations. First-year resident physicians (interns) who started training between 2007 and 2019. Depressive symptoms (9-item Patient Health Questionnaire [PHQ-9]) assessed at baseline and quarterly throughout internship. Among 16965 interns, baseline depressive symptoms increased from 2007 to 2019 (PHQ-9 score, 2.3 to 2.9; difference, 0.6 [95% CI, 0.3 to 0.8]). The prevalence of baseline predictors of greater increase in depressive symptoms with internship also increased across cohorts. Despite the higher prevalence of baseline risk factors, the average change in depressive symptoms with internship decreased 24.4% from 2007 to 2019 (change in PHQ-9 score, 4.1 to 3.0; difference, -1.0 [CI, -1.5 to -0.6]). This change across cohorts was greater among women (4.7 to 3.3; difference, -1.4 [CI, -1.9 to -0.9]) than men (3.5 to 2.9; difference, -0.6 [CI, -1.2 to -0.05]) and greater among nonsurgical interns (4.1 to 3.0; difference, -1.1 [CI, -1.6 to -0.6]) than surgical interns (4.0 to 3.2; difference, -0.8 [CI, -1.2 to -0.4]). In parallel to the decrease in depressive symptom change, there were increases in sleep hours, quality of faculty feedback, and use of mental health services and a decrease in work hours across cohorts. The decrease in work hours was greater for nonsurgical than surgical interns. Further, the increase in mental health treatment across cohorts was greater for women than men. Data are observational and subject to biases due to nonrandom sampling, missing data, and unmeasured confounders, limiting causal conclusions. Although depression during physician training remains high, the average increase in depressive symptoms associated with internship decreased between 2007 and 2019.

The health impacts of eviction: Evidence from the national longitudinal study of adolescent to adult health.

Eviction represents an urgent social and economic issue in the United States, with nearly two million evictions occurring annually in the U.S. Still, the population health impacts of evictions, as well as the pathways linking eviction to health, are not well documented or understood, particularly among young adults. Using nationally-representative, longitudinal data from the National Longitudinal Study of Adolescent to Adult Health (1994-2008) (n=9029), the present study uses a combination of analytic methods-including prospective lagged dependent variable regression models, inverse probabilities of treatment weighting, longitudinal first difference models, causal mediation techniques-to comprehensively assess whether and how evictions relate to depressive risk and self-rated health across early adulthood, paying particular attention to the stress-related pathways linking eviction and health. Results provide robust evidence of positive longitudinal associations between eviction and depressive risk, in particular. In the prospective regression models, young adults who experienced recent eviction had more depressive symptoms and worse self-rated health than those who were not evicted, net a host of background characteristics. Using treatment weighting techniques, results showed that young adults who experienced eviction had more depressive symptoms than those who were not evicted (5.921 vs. 4.998 depressive symptoms, p=0.003). Perceived social stress mediated nearly 18 percent of the associations between eviction and the depressive symptoms (p<0.001). In the first difference models, young people who experienced eviction between survey waves experienced greater increases in depressive symptoms over time compared to those who were not evicted, net of changes in other indicators of socioeconomic status and residential instability. Taken together, our results suggest that the recent surges in evictions in the U.S. serve as a potent threat to population health during the emerging adult period, with especially devastating consequences for low-income individuals and communities of color.

Psychological and Physical Health in Widowhood: Does Marital Quality Make a Difference?

We investigate how preloss marital quality is associated with changes in psychological distress and physical health among older widow(er)s. Using prospective data with a 2-year follow-up from the Health and Retirement Study, we selected 546 respondents who transitioned into widowhood. Respondents were classified as supportive, ambivalent, aversive, or neutral groups. The supportive and ambivalent group experienced greater increase in depressive symptoms compared to the aversive group, in widowhood. The aversive group showed greater increase in chronic conditions compared to the supportive group. Findings indicated that spousal loss may result in more psychological distress for those with supportive and ambivalent marital relationship. Yet, those with mostly negative accounts of their marriage may experience worsened physical health, albeit no increase in psychological distress. Understanding different benefits and challenges facing older individuals after a positive or negative marriage may help direct support and interventions efforts toward older couples during marriage and in widowhood.

Cognitive and Neuroimaging Profiles of Individuals With Dual Decline in Memory and Gait

Across 6 aging cohorts we showed that dual decline in memory and gait speed was associated with increased risk of dementia compared to memory or gait decline only. We now characterize dual decliners. Using longitudinal BLSA data, we examined associations of phenotypic groups with changes in cognition, depressive symptoms, and brain volumes in areas important for cognitive (dorsolateral prefrontal, medial temporal) and motor functions (precentral gyrus,striatum,thalamus,anterior cingulate cortex) using linear mixed effects models (usual agers=reference), adjusting for covariates. Compared to usual agers, dual decliners had faster decline in card rotation score, greater increase in CES-D, and greater atrophy in thalamus and anterior cingulate cortex. Rates of change in these parameters did not differ among the other three groups. Dual decliners experience faster decline in visuospatial ability, greater atrophy in selected motor areas, and greater increase in depressive symptoms, suggesting potential mechanisms underlying increased dementia risk in dual decliners.

Socioeconomic status and well-being during COVID-19: A resource-based examination.

The authors assess levels and within-person changes in psychological well-being (i.e., depressive symptoms and life satisfaction) from before to during the COVID-19 pandemic for individuals in the United States, in general and by socioeconomic status (SES). The data is from 2 surveys of 1,143 adults from RAND Corporation's nationally representative American Life Panel, the first administered between April-June, 2019 and the second during the initial peak of the pandemic in the United States in April, 2020. Depressive symptoms during the pandemic were higher than population norms before the pandemic. Depressive symptoms increased from before to during COVID-19 and life satisfaction decreased. Individuals with higher education experienced a greater increase in depressive symptoms and a greater decrease in life satisfaction from before to during COVID-19 in comparison to those with lower education. Supplemental analysis illustrates that income had a curvilinear relationship with changes in well-being, such that individuals at the highest levels of income experienced a greater decrease in life satisfaction from before to during COVID-19 than individuals with lower levels of income. We draw on conservation of resources theory and the theory of fundamental social causes to examine four key mechanisms (perceived financial resources, perceived control, interpersonal resources, and COVID-19-related knowledge/news consumption) underlying the relationship between SES and well-being during COVID-19. These resources explained changes in well-being for the sample as a whole but did not provide insight into why individuals of higher education experienced a greater decline in well-being from before to during COVID-19.

Interpersonal life stress, inflammation, and depression in adolescence: Testing Social Signal Transduction Theory of Depression.

Depression rates increase markedly for girls across the adolescent transition, but the social-environmental and biological processes underlying this phenomenon remain unclear. To address this issue, we tested a key hypothesis from Social Signal Transduction Theory of Depression, which posits that individuals who mount stronger inflammatory responses to social stress should exhibit greater increases in depressive symptoms following interpersonal life stress exposure than those who mount weaker inflammatory responses to such stress. Participants were 116 adolescent girls (Mage = 14.71) at risk for psychopathology, defined as having a history of mental health concerns (e.g., psychiatric treatment, significant symptoms) over the past 2 years. At baseline, we characterized their inflammatory reactivity to social stress by quantifying their salivary proinflammatory cytokine responses to a laboratory-based social stressor. Then, 9 months later, we assessed the interpersonal and noninterpersonal stressful life events that they experienced over the prior 9 months using an interview-based measure of life stress. As hypothesized, greater interpersonal life stress exposure was associated with significant increases in depression over time, but only for girls exhibiting stronger salivary tumor necrosis factor-α and interleukin-1β reactivity to social stress. In contrast, noninterpersonal stress exposure was unrelated to changes in depression longitudinally, both alone and when combined with youths' cytokine reactivity scores. These results are consistent with Social Signal Transduction Theory of Depression and suggest that heightened inflammatory reactivity to social stress may increase adolescents' risk for depression. Consequently, it may be possible to reduce depression risk by modifying inflammatory responses to social stress.
