Impact of Post-Stroke Post-Traumatic Stress Disorder

Introduction Post-Traumatic Stress Disorder (PTSD) is associated with exposure to traumatic events, especially in the military setting. However, patients who experience stroke may develop anxiety about their stroke event and may re-experience transient neurological symptoms as a result. A significant portion develop the persistent and disabling symptoms of PTSD. Methods At the University of South Florida, we conducted a single-center, IRB-approved, observational pilot study of 20 adult patients who were diagnosed with stroke or transient ischemic attack (TIA) in the previous 31 days to 1 year. Patients completed the post-traumatic stress disorder checklist-5 (PCL-5), Patient Health Questionnaire-9 (PHQ-9), Stroke specific Quality of Life Scale (SS-QOL-12), Modified Rankin Scale of disability (mRS), and National Institutes of Health Stroke Scale (NIHSS) and provided blood and saliva samples. Results All 20 subjects completed the PCL-5 and 19 subjects completed the follow up scales. Seven patients (35%) were found to have Post-Stroke Post-Traumatic Stress Disorder (PS-PTSD). Higher PCL-5 scores were significantly correlated with lower SS-QOL scores indicating worse quality of life (r = −0.709, P = .001) and higher PHQ-9 scores representing symptoms of depression (r = 0.727, P < 0.001). Conclusion Post-Stroke Post-Traumatic Stress Disorder (PS-PTSD) is prevalent after stroke and TIA with patients experiencing concurrent depressive symptoms, correlating with a worsened quality of life.

Predictors of ICU Surrogates' States of Concurrent Prolonged Grief, Posttraumatic Stress, and Depression Symptoms.

Scarce research explores factors of concurrent psychologic distress (prolonged grief disorder [PGD], posttraumatic stress disorder [PTSD], and depression). This study models surrogates' longitudinal, heterogenous grief-related reactions and multidimensional risk factors drawing from the integrative framework of predictors for bereavement outcomes (intrapersonal, interpersonal, bereavement-related, and death-circumstance factors), emphasizing clinical modifiability. Prospective cohort study. Medical ICUs of two Taiwanese medical centers. Two hundred eighty-eight family surrogates. None. Factors associated with four previously identified PGD-PTSD-depressive-symptom states (resilient, subthreshold depression-dominant, PGD-dominant, and PGD-PTSD-depression concurrent) were examined by multinomial logistic regression modeling (resilient state as reference). Intrapersonal: Prior use of mood medications correlated with the subthreshold depression-dominant state. Financial hardship and emergency department visits correlated with the PGD-PTSD-depression concurrent state. Higher anxiety symptoms correlated with the three more profound psychologic-distress states (adjusted odds ratio [95% CI] = 1.781 [1.562-2.031] to 2.768 [2.288-3.347]). Interpersonal: Better perceived social support was associated with the subthreshold depression-dominant state. Bereavement-related: Spousal loss correlated with the PGD-dominant state. Death circumstances: Provision of palliative care (8.750 [1.603-47.768]) was associated with the PGD-PTSD-depression concurrent state. Surrogate-perceived quality of patient dying and death as poor-to-uncertain (4.063 [1.531-10.784]) correlated with the subthreshold depression-dominant state, poor-to-uncertain (12.833 [1.231-133.775]), and worst (12.820 [1.806-91.013]) correlated with the PGD-PTSD-depression concurrent state. Modifiable social-worker involvement (0.004 [0.001-0.097]) and a do-not-resuscitate order issued before death (0.177 [0.032-0.978]) were negatively associated with the PGD-PTSD-depression concurrent and the subthreshold depression-dominant state, respectively. Apparent unmodifiable buffering factors included surrogates' higher educational attainment, married status, and longer time since loss. Surrogates' concurrent bereavement distress was positively associated with clinically modifiable factors: poor quality dying and death, higher surrogate anxiety, and palliative care-commonly provided late in the terminal-illness trajectory worldwide. Social-worker involvement and a do-not-resuscitate order appeared to mitigate risk.

Effects of postpartum PTSD on maternal mental health and child socioemotional development - a two-year follow-up study

BackgroundPostpartum posttraumatic stress disorder (PP-PTSD) is a prevalent, yet often unrecognized mental health problem, particularly in low- and middle-income countries. Moreover, the long-term effects of PP-PTSD symptoms on maternal well-being and child socioemotional development beyond the first year postpartum remain largely unknown. This study focused on the association between PP-PTSD symptoms within one year after childbirth and maternal depressive symptoms and child behavioral problems two years later.MethodsRussian women (n = 419) completed the City Birth Trauma Scale and the Edinburgh Postnatal Depression Scale evaluating symptoms of PP-PTSD and postpartum depression (PPD) via a web-based survey. Mothers also filled in the Beck Depression Inventory that assessed their depressive symptoms and the Child Behavior Checklist that assessed child’s behavioral problems 2.24 years later.ResultsThe regression analysis showed a significant association between PP-PTSD and elevated depressive symptoms 2 years later even after adjustment for PPD (β = 0.19, 95% Confidence Interval 0.11, 0.26, p < 0.01). Children of mothers with higher PP-PTSD symptoms had higher internalizing, externalizing, and total behavioral problems, independent of PPD and concurrent depressive symptoms (β > 0.12, p < 0.01 for all).ConclusionsChildbirth-related PTSD presents risk for maternal psychological well-being and child socioemotional development beyond comorbidity with maternal depression. Raising awareness about PP-PTSD among families, communities, healthcare providers, and policymakers is essential in order to decrease stigma of childbirth-related distress, particularly, in low- and middle-income countries like Russia, improve support system during the postpartum period, promote mother–infant bonding in affected women, and, thus, prevent long-term consequences of traumatic childbirth for maternal and child mental health outcomes.Clinical trial numberNot applicable.

Depression decreases immunity and PD-L1 inhibitor efficacy via the hypothalamic–pituitary–adrenal (HPA) axis in triple-negative breast cancer

BackgroundDepression weakens antitumor immunity, yet the underlying mechanisms linking depression and tumor growth remain unclear. This study examines the influence of depression on the hypothalamic–pituitary–adrenal (HPA) axis, immunological function, and effectiveness of immunotherapy in triple-negative breast cancer (TNBC) patients. MethodsA mouse model of comorbid TNBC and depression was established via chronic restraint stress (CRS) and 4T1 tumor transplantation. A programmed cell death ligand 1 (PD-L1) inhibitor was used to manage mice with TNBC, and the ability of metyrapone to reverse the immune system changes induced by HPA axis activation in depression was evaluated. Mouse peripheral blood was used to measure HPA axis activity, immune cell numbers and cytokine levels. ResultsDepression activates the HPA axis, leading to increased levels of glucocorticoids. Depression led to an increase in the B-cell number and a reduction in the CD4+ T-cell and CD8+ T-cell numbers, without a statistically significant difference in the regulatory T (Treg) cell number. Furthermore, depression increased the levels of the cytokines interferon-gamma (IFN-γ), interleukin (IL)-1β, IL-4, IL-6, IL-8, and tumor necrosis factor (TNF)-α while decreasing the levels of IL-2 and IL-10. Similar results were observed in the context of PD-L1 inhibitor therapy. The depressed mice presented an increased tumor burden and a poor response to the PD-L1 inhibitor. The application of metyrapone during PD-L1 inhibitor treatment resulted in partial restoration of these depression-related alterations. ConclusionsDepression reduces the effectiveness of PD-L1 inhibitors by altering the number of immune cells and the levels of cytokines through activation of the HPA axis. Translational relevanceDepression is common in breast cancer patients and is associated with reduced antitumor immunity. There is limited knowledge regarding the specific mechanisms through which depression impairs antitumor immunity. Immunotherapy, which promotes the restoration of antitumor immunity, represents a promising treatment strategy for TNBC patients. However, the efficacy of immunotherapy can be compromised by depressive symptoms and the administration of glucocorticoids during treatment. It is still uncertain whether increasing glucocorticoid levels can reduce the efficacy of immunotherapy in patients with depression. The potential benefits of combining immunotherapy with glucocorticoid inhibitors compared with immunotherapy alone need to be evaluated for TNBC patients with concurrent depressive symptoms. Therefore, further clarification of the specific mechanisms by which depression impairs antitumor immunity is needed to inform future optimization of immunotherapy strategies.

Experiences with discrimination during pregnancy in Canada and associations with depression and anxiety symptoms.

Experiences of discrimination reported during pregnancy are common and are associated with poor mental health and adverse birth outcomes. No Canadian studies have investigated interpersonal discrimination during pregnancy. This study aimed to quantify and identify lived-experiences of discrimination in a Canadian cohort of pregnant individuals, and examine associations with concurrent prenatal anxiety and depression symptoms. Pregnant individuals from the pan-Canadian Pregnancy During the Pandemic (PdP) study (n = 1943) completed the Everyday Discrimination Scale (EDS), demographic measures and self-report measures of depression and anxiety symptoms. Descriptive statistics and ANCOVA were used to assess prevalence of discrimination and associated mental health outcomes. Open-text responses (n = 189) to a question investigating reasons for discrimination were analyzed using conventional content analysis. Approximately three quarters (72%) of pregnant individuals experienced at least one instance of discrimination during their pregnancy or within the year prior. Pregnant individuals experiencing more frequent and/or more types of discrimination were more likely to identify as non-white, not be partnered, have lower socioeconomic status, and have a pre-pregnancy history of anxiety and depression. The most common attributions for interpersonal discrimination were gender, age, and education/income level. Pregnant individuals who experienced more frequent discrimination and/or more types of discrimination were more likely to report clinically significant symptoms of depression and anxiety (n = 623; 35.2% and 49.1%, respectively) compared to those who reported no discrimination (n = 539; 11.5% and 19.1%, respectively). Conventional content analysis of open-text responses generated the following main themes: (1) personal attributes and sociodemographic characteristics, (2) occupation, (3) the COVID-19 pandemic, (4) pregnancy and parenting, and (5) causes outside the self. Frequent discrimination was associated with more adverse concurrent mental health symptoms. Understanding experiences of discrimination can inform interventions that better address the needs of pregnant individuals and their infants.

Association of youth climate change worry with present and past mental health symptoms: a longitudinal population-based study

Young people are worried about climate change but the association with current and past mental health symptoms is rarely examined in longitudinal population-based samples. Drawing on a population-based birth cohort from the Canadian province of Quebec (n = 1325), this study used a cross-over design to (1) test the association between climate change worry at age 23-years and concurrent mental health symptoms assessed on standardised instruments, and (2) test the association between adolescent (15 and 17 years) symptoms of anxiety, depression, inattention-hyperactivity, and aggression-opposition and climate worry at age 23-years. Participant sex, cognitive ability, socioeconomic status, and parental mental health were adjusted for. Descriptive statistics showed that most participants were worried about climate change: 190 (14.3%) were extremely worried, 383 (28.9%) were very worried, 553 (41.7%) were somewhat worried, and 199 (15.0%) were not at all worried. In analysis 1, worry about climate change was associated with significantly higher concurrent anxiety, depression, and self-harm symptoms, even after adjustment for adolescent symptoms. In analysis 2, anxious adolescents were significantly more likely to be extremely worried about climate change six years later (RRR = 1.51, 95%CI = 1.10–2.07), while aggressive-oppositional adolescents were significantly less likely to be somewhat worried (RRR = 0.79, 95%CI = 0.63–0.0.99), very worried (RRR = 0.61, 95%CI = 0.48–0.78), or extremely worried (RRR = 0.51, 95%CI = 0.37–0.72). Taken together, participants who were worried about climate change had more concurrent mental health symptoms but were also more likely to have prior symptoms. Adolescents with higher anxiety were more likely to worry about climate change in early adulthood, while those with higher aggression-opposition were less likely to worry. Future studies should track climate worry longitudinally alongside symptoms using prospective follow-up studies.

Longitudinal Associations Between Scripted Attachment Representations in Late Adolescence and Depression in Adulthood in a Normative and a Higher-Risk Cohort

Attachment representations are increasingly operationalized as secure base script knowledge—one’s level of awareness of the temporal-causal schema that summarizes basic features of seeking and receiving effective support from caregivers when in distress. A method was recently developed to assess secure base script knowledge during the Adult Attachment Interview (AAIsbs), though its predictive validity for mental health outcomes is largely unknown. A series of pre-registered analyses, leveraging two large, longitudinal cohorts to assess the associations between AAIsbs and depression in emerging adults revealed that higher AAIsbs at age 18 years in the normative-risk sample, but not in a higher-risk cohort, predicted fewer depressive symptoms at age 30 years. In general, these associations were robust to concurrent depressive symptoms, sociodemographic and cognitive functioning covariates, and other traditional attachment representation measures. Findings support the importance of considering schematic attachment representations in developing interventions to improve young adults’ well-being.

Neighborhood Safety Concerns and the Onset of Depressive Symptoms Among Women: A Population-based Prospective Cohort Study in South Korea.

Neighborhood safety is crucial for the well-being of residents; however, longitudinal evidence is scarce. This study explored the association between neighborhood safety concerns and depressive symptoms among women. A nationally representative sample of 10,008 women was surveyed in 2016. Six dimensions of neighborhood safety concerns were assessed: crime, food, safety at night, traffic accidents, building and facility, and general safety. The total score for neighborhood safety concerns ranged from 6 to 24, with higher scores indicating greater concerns. Depressive symptoms were assessed using the 10-item version of the Center for Epidemiologic Studies Depression. For cross-sectional analyses, we explored how neighborhood safety concerns were associated with concurrent depressive symptoms at baseline. For the longitudinal analyses, we explored how they were associated with depressive symptom onset at the 2-year follow-up (2018) among women without depressive symptoms at baseline (n = 7,643). Logistic regressions were employed. The mean (standard deviation [SD]) of the neighborhood safety concern score was 12.7 (3.3). In the cross-sectional analysis, a 1-SD increase in neighborhood safety concern score was associated with 1.23-fold (95% CI: 1.13-1.35) increase in the odds of concurrent depressive symptoms at the baseline year. In the longitudinal analysis, a 1-SD increase in neighborhood safety concern score was associated with 1.15-fold (95% CI: 1.03-1.29) increase in the odds of experiencing the onset of depressive symptoms at the follow-up year. This study suggests that neighborhood safety concerns are risk factors for the development of depressive symptoms of female residents. Policy efforts are necessary to ensure community safety.

A bioecological longitudinal study of depressive symptoms from pregnancy to 36 months postpartum

PurposeDepressive symptoms during the perinatal period have broad and enduring health implications for birthing parents and their offspring. Rising prevalence rates of perinatal depression highlight the need for research examining factors influencing depressive symptoms during pregnancy, and trajectories during the early postnatal period. Grounded in bioecological systems theory, this longitudinal multimethod study examined whether prenatal bioecological factors predict depressive symptoms from pregnancy to 36 months postpartum. MethodsParticipants were 162 pregnant individuals, oversampled for high emotion dysregulation, who completed a life stress interview and physiological assessment during the 3rd trimester and a self-report measure of depression at five time-points (3rd trimester, within 48 h of birth, 7, 18, and 36 months postpartum). Multilevel models were used to test study aims. ResultsParticipants exhibited the highest levels of depressive symptoms at 3rd trimester, and substantial variability in depressive symptom trajectories over time. Lower resting respiratory sinus arrhythmia (RSA), an index of parasympathetic nervous system functioning, in the 3rd trimester was associated with higher concurrent depressive symptoms. Higher levels of stress related to partner relationships, finances, and health were concurrently associated with more depressive symptoms during pregnancy and decreases in depressive symptoms over time. Specifically, depressive symptoms decreased only for individuals who reported high levels of stress during pregnancy. LimitationsAlthough grounded in bioecological systems theory, this study did not assess the macrosystem. ConclusionsResults of this study underscore the importance of multilevel predictors of perinatal health and highlights potential targets for preventing depression and promoting well-being during the perinatal transition.

Shame and depressive symptoms in men: The moderating role of environmental mastery and purpose in life.

Feelings of shame are linked to increased risk for depression. Little is known about protective factors that may buffer this effect, particularly in men. Using prospective data from a community sample of Australian men, we examine the extent to which shame is associated with depressive symptoms, and the protective role of psychological wellbeing, specifically environmental mastery and purpose in life. Participants (n = 448) were from the longitudinal Men and Parenting Pathways (MAPP) Study. Measures were the Event Related Shame and Guilt Scale for shame, the DASS-21 for depressive symptoms and Ryff's Scales of Psychological Well-Being for environmental mastery and purpose in life. Linear regressions were used to test associations between shame and depressive symptoms concurrently and 1-year later, and the moderating effects of mastery and purpose in life. Shame was strongly associated with concurrent depressive symptoms (βunadj = .76, p < .001; βadj = .63, p < .001). This effect was weaker in men with high compared to low environmental mastery (β+1SD = .46, p < .001; β-1SD = .55, p < .001) and purpose in life (β+1SD = .48, p < .001; β-1SD = .62, p < .001). Shame also predicted subsequent depressive symptoms after adjustment for prior depressive symptoms (βunadj = .59, p = .001; βadj = .34, p = .004), although environmental mastery or purpose in life did not moderate these associations. Our findings suggest that promoting a sense of psychological wellbeing in men may confer protective proximal effects in the context of shame, potentially attenuating depression severity. The current study aligns with calls for strength-based approaches to reducing mental health problems in men.

Specificity and valence of adolescents’ turning point memory narratives: Relationships with depressive symptoms over time

Although recent research suggests that, for community youth, greater specific (episodic) detail in self-relevant turning point memory narratives predicts depressive symptoms over time, no research has investigated whether the narratives’ specificity similarly predicts depression. Therefore, we investigated whether recalling a specific (unique, 24-hour or less) turning point narrative predicted youth depressive symptoms concurrently and across 6 months (Study 1), and, for a subset of participants, three years (Study 2). We also examined whether the valence of the implication of the experience for self (the resolution) explained additional variance and interacted with memory specificity. For Study 1 (N = 320, M = 16.9 years, 81% female), a specific (rather than a non-specific) turning point predicted greater depressive symptoms concurrently but not longitudinally, whereas a negative resolution predicted both concurrent and longitudinal depressive symptoms. The moderation result showed that a specific turning point predicted escalating depressive symptoms across six months when the resolution was negative. Study 2 (N = 68) additionally showed that a specific turning point predicted increased depressive symptoms three years later. These findings contrast with research suggesting that specific memories are related to better mental health and highlight the complexity of the role of memory in emerging youth depression.

Prenatal insomnia disorder may predict concurrent and postpartum psychopathology: A longitudinal study.

While insomnia symptoms may be a risk factor for mental disturbances, few studies evaluated "Insomnia Disorder" and its relationship with perinatal psychopathology. Pregnant women were recruited during their last routine assessment before being hospitalized for delivery during the 3rd trimester at the Gynaecological Unit of the University Hospital of Ferrara and Udine, Italy, from January 2022 to January 2023. Our assessment included baseline evaluation (T0), and evaluations at 1 month (T1) and 3 months (T2) in the postpartum period, with specific questionnaires for insomnia disorder, such as Sleep Condition Indicator, mood and anxiety symptoms and psychosocial functioning, such as Edinburgh Postnatal Depression Scale, Mood Disorder Questionnaire, State-Trait Anxiety Inventory, Work and Social Adjustment Scale. At T0, 181 pregnant women were included. Insomnia disorder affected 22.3% at T0, 23.5% at T1 and 16.2% at T2. Women with insomnia disorder at baseline were significantly more affected by concurrent anxiety and depressive symptoms, had higher bipolar diathesis and poorer psychosocial functioning in the perinatal period. Prenatal insomnia disorder predicted anxiety (T0: odds ratio 4.44, p << 0.001; T1: odds ratio 4.009, p = 0.042) and depressive symptoms (T0: odds ratio 2.66, p = 0.015; T1: odds ratio 11.20, p = 0.001; T2: odds ratio 12.50 p = 0.049) in both the prenatal and postnatal period. It also predicted poor psychosocial function during the prenatal (odds ratio 3.55, p = 0.003) and postpartum periods (T1: odds ratio 2.33, p = 0.004). Insomnia disorder is emerging as an important prenatal factor that may contribute to concurrent and postpartum psychopathology.

Abstract P227: Association Between Depressive Symptoms and Insulin Resistance in Midlife Women: The Study of Women’s Health Across the Nation (SWAN)

Introduction: Recent meta-analyses and cross-sectional studies propose that insulin resistance (IR) is a transient and not a lasting feature of depression. However, longitudinal evidence is lacking, particularly in midlife women across the menopause and ethnically diverse cohorts. The goals of this study were to 1) assess the longitudinal association between IR and concurrent and prior depressive symptoms among midlife women and 2) determine if these associations vary by menopausal status and ethnicity. Methods: We included 2694 women (48.4% White, 27.3% Black, 6.5% Hispanic, 8.1% Chinese, and 9.7% Japanese) from The Study of Women’s Health Across the Nation (SWAN) followed for approximately 20 years. The Center for Epidemiologic Studies Depression Scale (CES-D) score was used to assess depressive symptoms (CES-D ≥16 indicating high depressive symptoms) and IR was obtained from the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) and log-transformed for analysis. Multivariable linear mixed regression was used to estimate IR as a function of concurrent and prior depressive symptoms adjusting for baseline and time-varying covariates. We tested interactions between depressive symptoms and 1) time-varying menopausal status and 2) race/ethnicity in relation to IR. Results: At baseline women (mean age 45.86 ± 2.70 years, 48.4% white) were premenopausal (54.7%) or early perimenopausal (45.3%). In separate adjusted models, neither concurrent high depressive symptoms nor high depressive symptoms from the prior visit were statistically associated with log-HOMA-IR. When both concurrent and prior visit depressive symptoms were included in the model, the estimated effect of concurrent high depressive symptoms was comparable and statistically significant. High depressive symptoms were associated with a 0.03 increase in log-HOMA-IR (95% CI: 0.01, 0.06), equivalent to a 3% change in HOMA-IR compared to women with low depressive symptoms. Interaction effects were detected between high depressive symptoms and race/ethnicity (P=0.005) but not with menopausal status in relation to HOMA. The relationship between concurrent high depressive symptoms and IR was driven by the association observed among Hispanic women [β=0.18, 95% CI: 0.18 (0.08, 0.27), a 20% change in HOMA-IR]. Conclusion: Current reporting of high depressive symptoms, but not prior reporting, was associated with elevated future IR over time among midlife women. This study provides longitudinal evidence in support of IR as a transient and not a lasting feature of depression. Moreover, the results suggest that Hispanic women with high depressive symptoms may be particularly susceptible to IR.

The effect of maternal childhood maltreatment on postpartum mother–child bonding and maternal hair glucocorticoids

ABSTRACT Background: Maternal experiences of childhood maltreatment (CM) constitute a risk factor for impairments in the mother–child relationship. One mechanism underlying this intergenerational transmission may be maternal hypothalamic–pituitary–adrenal axis dysregulation. Yet, few studies have examined different maltreatment subtypes, including emotional neglect, considered concurrent depressive symptoms, and used long-term integrated glucocorticoid measures. Objective: This study aimed to investigate associations between maternal CM history, postpartum glucocorticoids in hair, and mother–child bonding. In exploratory analyses, we tested whether specific subtypes of CM had differential implications for glucocorticoid secretion and bonding. Methods: During pregnancy, N = 269 mothers from the prospective cohort study DREAMHAIR provided retrospective information on CM and current information regarding psychological and hair-related variables. Hair samples were collected 8 weeks after delivery for quantification of maternal long-term hair cortisol and cortisone concentrations in 2-cm scalp-near hair samples. Mother–child bonding was measured 8 weeks and 14 months after birth using the Postpartum Bonding Questionnaire. Results: While bivariate correlations revealed significant associations of CM with bonding and hair cortisol, regression findings showed CM was associated with impaired bonding 8 weeks (overall CM trend-level; emotional neglect p = .038) and 14 months (emotional neglect trend level p = .041) after birth, however not after controlling for depressive symptoms at the time point of the outcome. In regression analyses, CM was not associated with maternal hair glucocorticoids 8 weeks postpartum. Maternal hair glucocorticoid concentrations were not related to mother–child bonding and did not mediate associations between CM and mother–child bonding. Conclusion: Data tentatively suggest that mothers with CM experiences, in particular emotional neglect, may be at risk for suboptimal bonding to their child, however current depressive symptoms seem to be more important. Our data provide no evidence for a crucial role of glucocorticoid secretion, yet aetiological processes of long-term glucocorticoid secretion and bonding are complex and more severely affected samples should be examined.

Association of white matter hyperintensities and clinical vascular burden with depressive symptoms in Black older adults.

Black older adults have a higher vascular burden compared to non-Hispanic White (NHW) older adults, which may put them at risk for a form of depression known as vascular depression (VaDep). The literature examining VaDep in Black older adults is sparse. The current study addressed this important gap by examining whether vascular burden was associated with depressive symptoms in Black older adults. Participants included 113 Black older adults from the Healthy Brain Project, a substudy of the Health, Aging, and Body Composition Study. In multiple regression analyses, clinical vascular burden (sum of vascular conditions) and white matter hyperintensity (WMH) volume predicted depressive symptoms as measured by the Center for Epidemiologic Studies Depression Scale, controlling for demographic variables. Follow-up analyses compared the associations in the Black subsample and in 179 NHW older adults. Higher total WMH volume, but not clinically-defined vascular burden, predicted higher concurrent depressive symptoms and higher average depressive symptoms over 4years. Similar associations were found between uncinate fasciculus (UF) WMHs and concurrent depressive symptoms and between superior longitudinal fasciculus WMHs and average depressive symptoms. The association between depressive symptoms and UF WMH was stronger in Black compared to NHW individuals. This research is consistent with the VaDep hypothesis and extends it to Black older adults, a group that has historically been underrepresented in the literature. Results highlight WMH in the UF as particularly relevant to depressive symptoms in Black older adults and suggest this group may be particularly vulnerable to the negative effects of WMH.

Association between precarious employment and the onset of depressive symptoms in men and women: a 13-year longitudinal analysis in Korea (2009-2022).

Increasing social concern surrounds the potential adverse health effects of precarious employment (PE). In this study, we explored the association between PE and the onset of depressive symptoms. A total of 11,555 Korean waged workers (5700 females) contributed 62,217 observations from 2009 to 2022. PE was operationalized as a multidimensional construct, including employment insecurity, income inadequacy and lack of rights and protection. Depressive symptoms were evaluated using the Center for Epidemiological Studies-Depression Scale (11-item version). The association between PE and the onset of depressive symptoms in the subsequent year was estimated using generalized estimating equations. Effect sizes were reported as odds ratio (OR) and 95% confidence interval (CI). The overall incidence of depressive symptoms was 8.3% during the study period. In cross-sectional analysis, daily employment, disguised employment, lower monthly wages and lack of social insurance coverage were associated with concurrent depressive symptoms in both men and women. Longitudinally, fixed-term employment (OR: 1.17, 95% CI: 1.07-1.29), daily employment (OR: 1.64, 95% CI: 1.45-1.85) and disguised employment (OR: 1.36, 95% CI: 1.17-1.57) were associated with the onset of depressive symptoms among the overall sample. Among men, the lowest quartiles of wage were associated with the onset of depressive symptoms (OR: 1.34, 95% CI: 1.13-1.60), while the absence of a trade union was associated among women (OR: 1.18, 95% CI: 1.01-1.39). Employment insecurity, inadequate income and lack of rights and protection may contribute to depressive symptoms. Therefore, PE serves as a significant social determinant of mental health among workers in Korea. Active policy efforts are warranted to improve the overall quality of employment in the workforce.

Peer popularity and self-discipline as protective factors against depressive symptoms in Chinese adolescents: Do boys and girls benefit equally?

The current study examined the concurrent and longitudinal protective effects of peer popularity and self-discipline (control, planning, and the ability to prioritize important things) against depressive symptoms among adolescents. We used multilevel modeling to examine the data of 1676 adolescents aged 12-15 years from the China Family Panel Studies (CFPS) survey, a large-scale panel survey with a nationally representative sample. Results showed that both peer popularity and self-discipline predicted lower levels of depressive symptoms measured concurrently. The buffering effect of self-discipline against concurrent depressive symptoms was stronger for girls than for boys, especially in middle adolescence. Peer popularity additionally predicted lower levels of depressive symptoms 4 years later, and this effect was stronger for girls than for boys. These patterns of results were maintained after controlling for self-rated physical health and society-level factors. We discuss these findings against the background of distinct traditional gender roles.

Maternal social support during and after pregnancy and child cognitive ability: examining timing effects in two cohorts.

Maternal anxiety, depression, and stress during and after pregnancy are negatively associated with child cognitive development. However, the contribution of positive maternal experiences, such as social support, to child cognitive development has received less attention. Furthermore, how maternal experience of social support during specific developmental periods impacts child cognitive development is largely unknown. Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC; n = 5784) and the Prediction and Prevention of Preeclampsia and Intrauterine Growth Restriction study (PREDO; n = 420), we investigated the associations between maternal perceived social support during and after pregnancy and child's general cognitive ability at 8 years of age, assessed with the Wechsler Intelligence Scale for Children (WISC). Bayesian relevant life course modeling was used to investigate timing effects of maternal social support on child cognitive ability. In both cohorts, higher maternal perceived social support during pregnancy was associated with higher performance on the WISC, independent of sociodemographic factors and concurrent maternal symptoms of depression and anxiety. In ALSPAC, pregnancy emerged as a sensitive period for the effects of perceived social support on child cognitive ability, with a stronger effect of social support during pregnancy than after pregnancy on child cognitive ability. Our findings, supported from two prospective longitudinal cohorts, suggest a distinct role of maternal perceived social support during pregnancy for cognitive development in children. Our study suggests that interventions aimed at increasing maternal social support during pregnancy may be an important strategy for promoting maternal and child well-being.
