RESUMO

Background: Posttraumatic stress disorder (PTSD) is characterized by severe distress and associated with cardiometabolic diseases. Studies in military and clinical populations suggest dysregulated metabolomic processes may be a key mechanism. Prior work identified and validated a metabolite-based distress score (MDS) linked with depression and anxiety and subsequent cardiometabolic diseases. Here, we assessed whether PTSD shares metabolic alterations with depression and anxiety and also if additional metabolites are related to PTSD. Methods: We leveraged plasma metabolomics data from three subsamples nested within the Nurses' Health Study II, including 2835 women with 2950 blood samples collected across three timepoints (1996-2014) and 339 known metabolites consistently assayed by mass spectrometrybased techniques. Trauma and PTSD exposures were assessed in 2008 and characterized as follows: lifetime trauma without PTSD, lifetime PTSD in remission, and persistent PTSD symptoms. Associations between the exposures and the MDS or individual metabolites were estimated within each subsample adjusting for potential confounders and combined in random-effects meta-analyses. Results: Persistent PTSD symptoms were associated with higher levels of the previously developed MDS for depression and anxiety. Out of 339 metabolites, we identified nine metabolites (primarily elevated glycerophospholipids) associated with persistent symptoms (false discovery rate<0.05). No metabolite associations were found with the other PTSD-related exposures. Conclusions: As the first large-scale, population-based metabolomics analysis of PTSD, our study highlighted shared and distinct metabolic differences linked to PTSD versus depression or anxiety. We identified novel metabolite markers associated with PTSD symptom persistence, suggesting further connections with metabolic dysregulation that may have downstream consequences for health.

RESUMO

Earlier studies have revealed microRNAs (miRNAs) as potential biomarkers for neurological conditions, however, such evidence on psychiatric outcomes is limited. We utilized the Normative Aging Study (NAS) cohort to investigate the associations between extracellular miRNAs (ex-miRNA) and psychiatric symptoms among a group of older male adults, along with the targeted genes and biological pathways. We studied 569 participants with miRNA profile primarily measured in extracellular vesicles isolated from plasma, and psychiatric symptoms reported over 1996-2014 with repeated measures. Global and dimension scales of psychiatric symptoms were measured via the administration of Brief Symptom Inventory (BSI) per visit covering nine aspects of psychiatric health, such as anxiety, depression, hostility, psychoticism, etc. Ex-miRNAs were profiled using small RNA sequencing. Associations of expression of 395 ex-miRNAs (present in >70% samples) with current mental status were assessed using single-miRNA as well as Least Absolute Shrinkage and Selection Operator (LASSO)-based multi-miRNAs linear mixed effects models adjusting for key demographic and behavioral factors. Biological functions were explored using pathway analyses. We identified ex-miRNAs associated with each BSI scale. In particular, hsa-miR-320d was consistently identified for two global scales. Similar overlapping miRNAs across global and dimension scores included hsa-miR-379-3p, hsa-miR-1976, hsa-miR-151a-5p, hsa-miR-151b, hsa-miR-144-3p, etc. Top KEGG pathways for identified miRNAs included p53 signaling, Hippo signaling, FoxO signaling, protein processing in endoplasmic reticulum and several pathways related with cancer and neurological diseases. This study provided early evidence supporting the associations between extracellular miRNAs and psychiatric conditions. MiRNAs may serve as biomarkers of subclinical psychiatric illness in older adults.

RESUMO

OBJECTIVE: Positive affect may influence health by promoting physical activity, but evidence evaluating this association is mostly cross-sectional and cannot discern directionality. This study used a counterfactual-based framework to estimate the causal effect of positive affect on physical activity patterns over 25 years, accounting for potential reverse associations. METHOD: Data were from 3,352 participants in the Coronary Artery Risk Development in Young Adults study. Repeated assessments of positive affect and physical activity were collected from 1990 to 2016. Longitudinal associations were evaluated in two ways: (a) using baseline positive affect in traditional linear mixed models that accounted for reverse causal associations by adjusting for baseline physical activity, and (b) using marginal structural models that treated positive affect as a time-varying exposure, thus accounting for dynamic reverse causal associations due to bidirectional relationships. RESULTS: Fully adjusted traditional models found no association with physical activity at the first follow-up assessment, but positive affect was related to a slower decline in physical activity over time. Marginal structural models similarly found that positive affect was unrelated to physical activity at the first follow-up assessment but robustly associated with a slower decline in activity levels (5-year change: ß = -3.33, 95% confidence interval [CI] = -5.80, -0.86; difference in 5-year change per 1 - SD positive affect: ß = 4.99, 95% CI = 2.52, 7.46). CONCLUSIONS: Positive affect may play a causal role in slowing the decline in physical activity adults generally experience during through midlife. Efforts to enhance positive affect at the population level may be a promising new approach to help individuals stay active as they age. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

Psychosocial stress may increase ovarian cancer risk and accelerate disease progression. We examined the association between caregiver burden, a common stressor, and risk of epithelial ovarian cancer. We prospectively followed 67,724 women in the Nurses' Health Study (NHS; 1992-2012) and 70,720 women in the NHSII (2001-2009) who answered questions on informal caregiving (i.e., caregiving outside of work). Women who reported no informal caregiving were considered non-caregivers while, among women who provided care outside of work, caregiver burden was categorized by time spent caregiving and perceived stress from caregiving. For the 34% of women who provided informal care for ≥15 hours per week, 42% described caregiving as moderately to extremely stressful. Pooled multivariate analyses indicated no difference in ovarian cancer risk for women providing ≥15 hours of care per week compared to non-caregivers (hazard ratio (HR)=0.96; 95% confidence interval (CI): 0.79-1.18), and no association was evident for women who reported moderate or extreme stress from caregiving compared to non-caregivers (HR=0.96; 95% CI: 0.75-1.22). Together with prior work evaluating job strain and ovarian cancer risk, our findings suggest that, when evaluating a stressor's role in cancer risk, it is critical to consider how the stressor contributes to the overall experience of distress.

RESUMO

Importance: Supporting healthy aging is a US public health priority, and gratitude is a potentially modifiable psychological factor that may enhance health and well-being in older adults. However, the association between gratitude and mortality has not been studied. Objective: To examine the association of gratitude with all-cause and cause-specific mortality in later life. Design, Setting, and Participants: This population-based prospective cohort study used data from self-reported questionnaires and medical records of 49 275 US older female registered nurses who participated in the Nurses' Health Study (2016 questionnaire wave to December 2019). Cox proportional hazards regression models estimated the hazard ratio (HR) of deaths by self-reported levels of gratitude at baseline. These models adjusted for baseline sociodemographic characteristics, social participation, physical health, lifestyle factors, cognitive function, and mental health. Data analysis was conducted from December 2022 to April 2024. Exposure: Gratitude was assessed with the 6-item Gratitude Questionnaire, a validated and widely used measure of one's tendency to experience grateful affect. Main Outcomes and Measures: Deaths were identified from the National Death Index, state statistics records, reports by next of kin, and the postal system. Causes of death were ascertained by physicians through reviewing death certificates and medical records. Results: Among the 49 275 participants (all female; mean [SD] age at baseline, 79 [6.16] years), 4608 incident deaths were identified over 151 496 person-years of follow-up. Greater gratitude at baseline was associated with a lower hazard of mortality in a monotonic fashion. For instance, the highest tertile of gratitude, compared with the lowest tertile, was associated with a lower hazard of all-cause deaths (HR, 0.91; 95% CI, 0.84-0.99) after adjusting for baseline sociodemographic characteristics, social participation, religious involvement, physical health, lifestyle factors, cognitive function, and mental health. When considering cause-specific deaths, death from cardiovascular disease was inversely associated with gratitude (HR, 0.85; 95% CI, 0.73-0.995). Conclusions and Relevance: This study provides the first empirical evidence suggesting that experiencing grateful affect is associated with increased longevity among older adults. The findings will need to be replicated in future studies with more representative samples.

RESUMO

Previous studies have examined how various aspects of positive psychological well-being (PPWB) independently relate to healthy aging, yet a notable gap remains in understanding the effects of their overlap (i.e., shared variance). We used data from two longitudinal cohorts, the Midlife Development in the United States Study and the Health and Retirement Study (N = 3,302 and 7,209), each of which assessed hedonic and eudaimonic facets of PPWB (positive affect, purpose in life, personal growth, and self-acceptance) and tracked mortality status across 14-15 years of follow-up. We derived a global factor identifying elements common across PPWB facets and also specific PPWB factors from a bifactor model. Then, we examined if higher PPWB levels (global and specific) are associated with mortality risk. Across cohorts, higher global well-being factor levels were associated with reduced mortality risk, even after adjusting for a range of potential confounders. Fewer independent associations were evident with the specific PPWB factors. Findings suggest that variance common across hedonic and eudaimonic facets of PPWB is associated with lower mortality risk. Considering the shared versus unique effects of different PPWB facets can offer valuable insights for theorizing mechanisms underlying health benefits of PPWB and guiding decisions about intervention targets.

RESUMO

OBJECTIVE: Optimism and purpose in life are associated with improved health outcomes. More information is needed on biological mechanisms, including immunosenescence. We investigated if psychological well-being is associated with healthier immunosenescence-related measures including naïve and terminally differentiated CD4+ and CD8+ T cell percentages, CD4+:CD8+, and cytomegalovirus (CMV) IgG response. METHODS: Participants were adults over age 50 from the Health and Retirement Study. Optimism was measured using the Life Orientation Test Revised. Purpose in life was assessed using the subscale from the Ryff psychological well-being measure. We examined the cross-sectional associations of optimism and purpose in life with measures of T cell subsets using linear regression and with CMV IgG using ordered logit regression, controlling for potential confounding factors. RESULTS: The final analytic sample ranged from 7250 to 7870. After adjusting for sociodemographic factors, a 1-SD increment in optimism was associated with the percentage of naïve CD4+ T cells increasing by 0.6 (95%CI 0.2%, 1.0%). A 1-SD increment in purpose in life was associated with the percentage of naïve CD4+ T cells increasing by 0.9 (95%CI 0.5%, 1.3%) after adjusting for sociodemographic factors and the association was maintained after further adjustments for health conditions, depression, and health behaviors. For naïve CD8+ T cell percentages, CD4:CD8 ratios, and CMV IgG antibodies, associations were seen only in models that adjusted for age. No significant associations were seen in any models for the terminally differentiated CD4+ and CD8+ T cells. CONCLUSIONS: We found associations of optimism and purpose in life with naïve CD4+ T cell percentages.

RESUMO

OBJECTIVE: Psychological factors, including psychological distress and well-being, have been associated with cardiometabolic disease risk. Here, we examined whether a psychological process, namely how individuals cope with stressors, relates to such risk, which has been understudied. METHOD: During 2004-2006, 2,142 participants without heart disease and diabetes from the Midlife in the U.S. study completed a validated coping inventory assessing six strategies (positive reinterpretation and growth, active coping, planning, focus on and venting of emotion, denial, and behavioral disengagement) and relevant covariates. As a proxy for coping flexibility, participants were also classified as having lower, moderate, or greater variability in their use of these strategies. Heart disease and diabetes were documented in 2013-2015. Logistic regressions modeled adjusted odds ratios (AORs) and 95% confidence intervals (CIs) of developing heart disease and diabetes, separately, with coping exposures. RESULTS: In sociodemographic-adjusted models, greater use of adaptive strategies predicted lower diabetes risk (e.g., positive reinterpretation and growth: AOR = 0.83; 95% CI [0.72, 0.96]); estimates were weaker for maladaptive strategies, and all strategies were unrelated to heart disease. All associations for coping variability were null. In secondary analyses, greater use of adaptive strategies predicted lower heart disease risk in more educated participants only (e.g., active coping: AOR = 0.71; 95% CI [0.55, 0.92]) and lower diabetes risk in females only (e.g., planning: AOR = 0.75; 95% CI [0.61, 0.91]). Results were maintained additionally adjusting for health, behavioral, and social factors. CONCLUSIONS: Findings suggest sex and education differences in coping's association with heart disease and diabetes. Future studies should recognize adaptive strategies may be more potent for health among certain populations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMO

BACKGROUND AND OBJECTIVE: This study examined the potential influence of pre-pandemic psychological resilience on use of approach or avoidant coping styles and strategies to manage stress during the COVID-19 pandemic. We hypothesized that higher resilience would be associated with more approach coping and less avoidant coping. DESIGN AND METHODS: Longitudinal cohort data were from the Nurses' Health Study II, including 13,143 female current and former healthcare professionals with pre-pandemic lifetime trauma. Pre-pandemic resilience was assessed between 2018-2019 and current coping during the outbreak of the pandemic in the United States (May-August 2020). Multiple linear regression model results identified associations between continuous pre-pandemic resilience scores and use of approach and avoidant coping styles, as well as individual coping strategies, adjusting for relevant covariates. RESULTS: Greater resilience was associated with higher use of approach coping (ß = 0.06, 95% CI 0.05, 0.08) and lower use of avoidant coping styles (ß = -0.39, 95% CI -0.41, -0.38). Higher pre-pandemic resilience was also associated with use of eight (distraction [ß = -0.18, 95% CI -0.20, -0.16], substance use [ß = -0.15, 95% CI -0.17, -0.13], behavioral disengagement [ß = -0.29, 95% CI -0.30, -0.27], self-blame [ß = -0.44, 95% CI -0.45, -0.42], emotional support (ß = 0.03, 95% CI 0.01, 0.05), positive reframing [ß = 0.13, 95% CI 0.12, 0.15], humor [ß = 0.03, 95% CI 0.01, 0.05] and religion [ß = 0.06, 95% CI 0.04, 0.08]) of the nine coping strategies in expected directions. CONCLUSION: Findings have important implications for intervention or even prevention efforts to support vulnerable groups, such as women with prior trauma histories, during this and other immensely stressful times. Supporting or building psychological resilience following trauma may promote effective coping in times of future stress.

RESUMO

OBJECTIVE: Prior work suggests psychological resilience to trauma may protect not only mental but also physical health. This study examined the relationship of pre-pandemic psychological resilience to lifetime trauma with self-reported COVID-19 infection and symptoms during the early years of the COVID-19 pandemic. METHODS: Data are from 18,670 longitudinal cohort participants in the Nurses' Health Study II. Based on prior evidence that trauma and subsequent distress can increase infection risk and severity, and that psychological assets may offset this risk, we hypothesized higher versus lower psychological resilience to prior trauma would be associated with lower risk for COVID-19 infection. Pre-pandemic resilience was assessed via self-report between 2017-2019 based on self-reported lifetime trauma exposure and psychological health. COVID-19 infection and symptoms were self-reported on 7 questionnaires administered between May 2020 - October 2021, from which we derived a composite outcome measure of probable COVID-19 infection, defined as having 3+ COVID-19 symptoms (out of 9) and/or a positive COVID-19 test result at any single assessment. RESULTS: Multivariable regression revealed significant associations between higher pre-pandemic resilience scores and lower risk for probable COVID-19 infection, adjusting for socio-demographic and COVID-19-related risk factors (RR = 0.90 [95% CI 0.87, 0.93]). Considering subcomponents of the composite COVID-19 infection measure separately, pre-pandemic resilience was significantly associated with lower risk of reported symptoms (RR = 0.83 [95% CI 0.79, 0.88]), but not with a positive test result alone (RR = 0.96 (95% CI 0.91, 1.01]). CONCLUSION: Identifying protective factors for infection risk may help inform psychosocial interventions to improve health outcomes.

RESUMO

OBJECTIVES: Purpose in life has been associated with diverse health outcomes; however, few studies have examined its associations with progressive motor decline in older adults. We tested if higher purpose would be associated with lower likelihood of incident parkinsonism as well as with lower levels and slower rates of increase in parkinsonian signs. METHODS: Participants were 2,626 older adults from the Rush Memory and Aging Project and Minority Aging Research Study followed for an average of 7.2 years (standard deviation [SD] = 4.6). Purpose was measured using the purpose in life subscale of the modified Ryff's and Keyes's measure of psychological well-being. Four parkinsonian signs (i.e., parkinsonian gait, rigidity, bradykinesia, and tremor) were assessed using the United Parkinson's Disease Rating Scale. We examined purpose with risk of developing incident parkinsonism using Cox proportional hazards models. We also used linear mixed-effect models to assess the association between purpose and parkinsonian sign trajectories. RESULTS: After including demographics, health conditions, and health behaviors in the model, for a 1-SD increase in purpose, the hazards ratio for incident parkinsonism was 0.88 (95% confidence interval [CI] 0.80, 0.97). A 1-SD increase in purpose was associated with a -0.19 (95% CI -0.24, -0.15) point lower score in the global parkinsonian summary score at baseline but no differences in rate of change were evident. DISCUSSION: Higher purpose was associated with lower hazards of incident parkinsonism and lower levels of parkinsonian signs at baseline. Associations were seen even after adjustment for a wide range of covariates. Findings suggest higher purpose may contribute to maintenance of healthy physical function among older adults.

RESUMO

Importance: Identifying factors contributing to sustained physical functioning is critical for the health and well-being of the aging population, especially as physical functioning may precede and predict subsequent health outcomes. Prior work suggests optimism may protect health, but less is known about the association between optimism and objective physical functioning measures as individuals age. Objective: To evaluate the longitudinal association between optimism and 3 physical functioning measures. Design, Setting, and Participants: This was a prospective cohort study using data from the Women's Health Initiative (WHI) with participants recruited from 1993 to 1998 and followed up over 6 years. Data analysis was conducted from January 2022 to July 2022. Participants included postmenopausal women older than 65 years recruited from 40 clinical centers in the US. Exposure: Optimism was assessed at baseline using the Life Orientation Test-Revised. Main Outcomes and Measures: Physical functioning was measured at 4 time points across 6 years by study staff evaluating performance in grip strength, timed walk, and chair stands. Results: The final analytic sample included 5930 women (mean [SD] age, 70 [4] years). Linear mixed-effects models controlling for demographics, depression, health status, and health behaviors showed that higher optimism was associated with higher grip strength (ß = 0.36; 95% CI, 0.21-0.50) and number of chair stands (ß = 0.05; 95% CI, 0.01-0.10) but not timed walk at baseline. Higher optimism was also associated with slower rates of decline in timed walk (ß = -0.09; 95% CI, -0.13 to -0.04) and number of chair stands (ß = 0.01; 95% CI, 0-0.03) but not grip strength over time. Cox proportional hazards models showed that higher optimism was associated with lower hazards of reaching clinically defined thresholds of impairment for all 3 outcomes over 6 years of follow-up. For example, in fully adjusted models, for a 1-SD increase in optimism, hazard ratios for reaching impairment thresholds were 0.86 (95% CI, 0.80-0.92) for grip strength, 0.94 (95% CI, 0.88-1.01) for timed walk, and 0.91 (95% CI, 0.85-0.98) for chair stands. Conclusion and Relevance: In this cohort study of postmenopausal women, at baseline, higher optimism was associated with higher grip strength and number of chair stands but not with the time it took to walk 6 m. Higher optimism at baseline was also associated with maintaining healthier functioning on 2 of the 3 performance measures over time, including less decline in walking speed and in number of chair stands women could perform over 6 years of follow-up. Given experimental studies suggesting that optimism is modifiable, it may be a promising target for interventions to slow age-related declines in physical functioning. Future work should explore associations of optimism with maintenance of physical functioning in diverse populations.

RESUMO

PURPOSE: Positive dimensions of psychological well-being in adolescence may help youth preserve cardiometabolic health (CMH) as they age, but little is known about which aspects of well-being matter most and for whom. This study examines the differential impact of five dimensions of adolescent psychological well-being on CMH maintenance in adulthood and considers social patterning in both their distribution and respective health benefits. METHODS: Data were from the National Longitudinal Study of Adolescent Health (N = 3,464), five dimensions of psychological well-being were identified at baseline (1994-1995; mean age = 15 years): happiness, optimism, self-esteem, belonging, and feeling loved. CMH was measured using seven biomarkers related to chronic disease risk in 2008 (mean age = 28 years) and 2016-2018 (mean age = 38 years): high-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, systolic blood pressure, diastolic blood pressure, hemoglobin A1c, C-reactive protein, and body mass index. CMH maintenance in adulthood was characterized as having healthy levels of ≥6 biomarkers at each follow-up. RESULTS: Youth who reported higher levels of belonging in the teen years were more likely to maintain CMH across young adulthood than those who reported lower levels, regardless of one's social standing (ORper 1-standard deviation = 1.23, 95% CI = 1.03-1.46). Associations with other dimensions of well-being were heterogeneous by sex and race and ethnicity, while differences by socioeconomic factors were less apparent. DISCUSSION: Fostering belonging through supportive social environments may help set youth on positive health trajectories and prevent chronic disease across the lifespan.

RESUMO

OBJECTIVE: Eudaimonic facets of psychological well-being (PWB), like purpose in life and sense of mastery, are associated with healthy aging. Variation in the gut microbiome may be one pathway by which mental health influences age-related health outcomes. However, associations between eudaimonic PWB and the gut microbiome are understudied. We examined whether purpose in life and sense of mastery, separately, were associated with features of the gut microbiome in older women. METHODS: Participants were from the Mind-Body Study ( N = 206, mean age = 61 years), a substudy of the Nurses' Health Study II cohort. In 2013, participants completed the Life Engagement Test and the Pearlin Mastery Scale. Three months later, up to two pairs of stool samples were collected, 6 months apart. Covariates included sociodemographics, depression, health status, and health behaviors. Analyses examined associations of PWB with gut microbiome taxonomic diversity, overall community structure, and specific species/pathways. To account for multiple testing, statistical significance was established using Benjamini-Hochberg adjusted p values (i.e., q values ≤0.25). RESULTS: We found no evidence of an association between PWB and gut microbiome alpha diversity. In multivariate analysis, higher purpose levels were significantly associated with lower abundance of species previously linked with poorer health outcomes, notably Blautia hydrogenotrophica and Eubacterium ventriosum ( q values ≤0.25). No significant associations were found between PWB and metabolic pathways. CONCLUSIONS: These findings offer early evidence suggesting that eudaimonic PWB is linked with variation in the gut microbiome, and this might be one pathway by which PWB promotes healthy aging.

RESUMO

Nature contact has associations with emotional ill-being and well-being. However, the mechanisms underlying these associations are not fully understood. We hypothesised that increased adaptive and decreased maladaptive emotion regulation strategies would be a pathway linking nature contact to ill-being and well-being. Using data from a survey of 600 U.S.-based adults administered online in 2022, we conducted structural equation modelling to test our hypotheses. We found that (1) frequency of nature contact was significantly associated with lesser emotional ill-being and greater emotional well-being, (2) effective emotion regulation was significantly associated with lesser emotional ill-being and greater emotional well-being, and (3) the associations of higher frequency of nature contact with these benefits were partly explained via emotion regulation. Moreover, we found a nonlinear relationship for the associations of duration of nature contact with some outcomes, with a rise in benefits up to certain amounts of time, and a levelling off after these points. These findings support and extend previous work that demonstrates that the associations of nature contact with emotional ill-being and well-being may be partly explained by changes in emotion regulation.

RESUMO

AIM: Given reports of increased prevalence of PTSD symptoms at COVID-19 pandemic onset, we aimed to assess the prevalence of posttraumatic stress disorder (PTSD) symptoms at pandemic onset in individuals with and without systemic autoimmune rheumatic disease (SARD). METHODS: In May 2020, we invited 6678 patients to complete the Brief Trauma Questionnaire and the Posttraumatic Stress Disorder Checklist (PCL-5), validated PTSD symptom screenings. We compared responses from patients with and without SARD using multivariable logistic regression. RESULTS: We received 1473 responses (22% response rate) from 5/2020 to 9/2021 (63 with prior PTSD diagnoses, 138 with SARD history). The SARD population was more female (p .0001) and had a higher baseline prevalence of stress disorders (56% vs. 43%, p .004). SARD subjects reported more experiences with life-threatening illness, 60%, versus 53% among those without SARD (p .13), and more antidepressant or anxiolytic medication use pre-pandemic (78% vs. 59%, p .0001). Adjusting for pre-pandemic PTSD diagnosis, younger age and history of stress disorder were the most significant predictors of PCL-5 positivity. There were no significant differences in PCL-5 score or positivity among those with or without SARD. CONCLUSION: In this population, patients with SARD had a higher pre-COVID-19 prevalence of stress-related conditions, but it was not the case that they had an increased risk of PTSD symptoms in the early pandemic. Younger individuals, those with baseline depression, anxiety, or adjustment disorders, and those taking antidepressant or anxiolytic medications were more likely to have PTSD symptoms in the first waves of the COVID-19 pandemic.

RESUMO

BACKGROUND: Post-traumatic stress disorder (PTSD) is associated with cognitive impairments. It is unclear whether problems persist after PTSD symptoms remit. METHODS: Data came from 12 270 trauma-exposed women in the Nurses' Health Study II. Trauma and PTSD symptoms were assessed using validated scales to determine PTSD status as of 2008 (trauma/no PTSD, remitted PTSD, unresolved PTSD) and symptom severity (lifetime and past-month). Starting in 2014, cognitive function was assessed using the Cogstate Brief Battery every 6 or 12 months for up to 24 months. PTSD associations with baseline cognition and longitudinal cognitive changes were estimated by covariate-adjusted linear regression and linear mixed-effects models, respectively. RESULTS: Compared to women with trauma/no PTSD, women with remitted PTSD symptoms had a similar cognitive function at baseline, while women with unresolved PTSD symptoms had worse psychomotor speed/attention and learning/working memory. In women with unresolved PTSD symptoms, past-month PTSD symptom severity was inversely associated with baseline cognition. Over follow-up, both women with remitted and unresolved PTSD symptoms in 2008, especially those with high levels of symptoms, had a faster decline in learning/working memory than women with trauma/no PTSD. In women with remitted PTSD symptoms, higher lifetime PTSD symptom severity was associated with a faster decline in learning/working memory. Results were robust to the adjustment for sociodemographic, biobehavioral, and health factors and were partially attenuated when adjusted for depression. CONCLUSION: Unresolved but not remitted PTSD was associated with worse cognitive function assessed six years later. Accelerated cognitive decline was observed among women with either unresolved or remitted PTSD symptoms.

RESUMO

PURPOSE: Given the burden of depression in young adulthood, identifying protective early life factors is important. Protective factors like positive psychological well-being may be challenging to assess via conventional methods if early adolescents lack personal insight or informants disagree. We investigated whether essays written by 11-year-olds could indicate the presence of positive psychological well-being and predict depressive symptom levels in young adulthood, beyond informant reports of problematic behaviors. METHODS: Data were from 4,599 individuals in the 1958 National Child Development Study who wrote an essay at age 11 about how they imagined their life at age 25. Coders rated essays for seven facets of positive psychological well-being, which were averaged together (α = 0.92). Participants self-reported depressive symptoms (yes/no) at age 23 on the 24-item Malaise Inventory. Depressive symptoms were modeled as a sum, both continuously (range = 0-24) and dichotomously (depressed: total scores ≥8). Linear and logistic regressions adjusted for relevant age 11 covariates including teacher-reported internalizing and externalizing behaviors. RESULTS: Unadjusted logistic regression showed a 1-SD higher positive psychological well-being score in early adolescence was associated with reduced odds of being depressed 12 years later (odds ratio = 0.83, 95% confidence interval [0.75, 0.93], p = .001). Associations remained when adjusting for all covariates (odds ratio = 0.87, 95% confidence interval [0.78, 0.98], p = .02); patterns were similar with continuous depressive symptoms. DISCUSSION: A well-being measure derived from the words of 11-year-olds was associated with young adult depressive symptoms independent of teacher-reported internalizing and externalizing behaviors. Incorporating early adolescents' perspectives on positive functioning provides valuable information about current and future health beyond problem behaviors.
