[PMID: 38962694 PMCID: PMC11219970 DOI: 10.1016/j.ynstr.2024.100652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 05/02/2024] [Accepted: 05/27/2024] [Indexed: 07/05/2024] Open
Abstract
Adverse early-life experiences (ELA) affect a majority of the world's children. Whereas the enduring impact of ELA on cognitive and emotional health is established, there are no tools to predict vulnerability to ELA consequences in an individual child. Epigenetic markers including peripheral-cell DNA-methylation profiles may encode ELA and provide predictive outcome markers, yet the interindividual variance of the human genome and rapid changes in DNA methylation in childhood pose significant challenges. Hoping to mitigate these challenges we examined the relation of several ELA dimensions to DNA methylation changes and outcome using a within-subject longitudinal design and a high methylation-change threshold. DNA methylation was analyzed in buccal swab/saliva samples collected twice (neonatally and at 12 months) in 110 infants. We identified CpGs differentially methylated across time for each child and determined whether they associated with ELA indicators and executive function at age 5. We assessed sex differences and derived a sex-dependent 'impact score' based on sites that most contributed to methylation changes. Changes in methylation between two samples of an individual child reflected age-related trends and correlated with executive function years later. Among tested ELA dimensions and life factors including income to needs ratios, maternal sensitivity, body mass index and infant sex, unpredictability of parental and household signals was the strongest predictor of executive function. In girls, high early-life unpredictability interacted with methylation changes to presage executive function. Thus, longitudinal, within-subject changes in methylation profiles may provide a signature of ELA and a potential predictive marker of individual outcome.

Abstract
Importance Early life adversity is associated with higher risk of many adult health problems, including mental illness, substance abuse, suicide attempt, and chronic diseases. Many previous studies investigated adversities one at a time or investigated the health toll associated with the cumulative number of adversities. Objective To examine the co-occurrence of adversities among children and how specific patterns of adversities are associated with neurocognitive development. Design, Setting, and Participants This cohort study used data from the Collaborative Perinatal Project (CPP), which enrolled a national sample of women during pregnancy and followed their offspring to ages 7 to 8 years, between 1959 and 1974. The CPP was a community-based study conducted in 12 US medical centers. The CPP sample was ascertained through prenatal clinics and is diverse with respect to race and socioeconomic status. Data analysis was performed from August 2023 to March 2024. Exposures A latent class analysis was conducted of 12 adverse childhood experiences that occurred between birth and 7 years to identify common patterns of childhood adversities. Main Outcomes and Measures Five neurocognitive tests were used to measure children's visual-motor, sensory-motor, auditory-vocal, intelligence quotient, and academic skills. Results The analysis sample included 49 853 offspring (25 226 boys [50.6%]); 24 436 children (49.0%) had low probability of experiencing any adversity, whereas the remaining half were classified into 5 groups reflecting distinct patterns of childhood adversities: parental harshness and neglect, 1625 children (3.3%); parental separation and poverty, 8731 children (17.5%); family instability, 3655 children (7.3%); family loss, instability, and poverty, 1505 children (3.0%); and crowded housing and poverty, 9901 children (19.9%). Children in 4 of these groups had lower neurocognitive scores than children with a low probability of experiencing adversity, with standardized mean differences ranging from -0.07 (95% CI, -0.11 to -0.03) to -0.86 (95% CI, -1.06 to -0.65). Conclusions and Relevance These findings suggest that adverse childhood experiences are associated with deficits in children's neurocognitive functions. It is important to understand the complexity in children's exposure to adversity and the resulting developmental consequences, as well as the underlying mechanisms, to help support children exposed to adversity and foster healthier and resilient trajectories of development.

Abstract
The present study examined three empirically-derived childhood adversity dimensions as predictors of social, psychological, and symptom outcomes across three prospective assessments of a young adult sample. Participants were assessed five times over eight years with semi-structured interviews and questionnaires. The analyses used the dimensions underlying multiple subscales from well-established childhood adversity measures administered at the first two assessment waves (described in a previous report). Outcome data pertain to the last three assessment waves, with sample sizes ranging from 89 to 169. As hypothesized, the childhood adversity dimensions demonstrated overlapping and differential longitudinal associations with the outcomes. Deprivation predicted the negative (deficit-like) dimension of psychosis, while Threat and Intrafamilial Adversity predicted the positive (psychotic-like) dimension. Depression and anxiety symptoms were predicted by different childhood adversity dimensions over time. Furthermore, Threat predicted a smaller and less diverse social network, Intrafamilial Adversity predicted anxious attachment, and Deprivation predicted a smaller social network, anxious and avoidant attachment, perceived social support, and loneliness. The three adversity dimensions combined accounted for moderate to large proportions of variance in several outcomes. These results extend prior work by identifying associations of three meaningful dimensions of childhood adversity with different risk profiles across psychological, social, and psychopathological domains. The findings enhance our understanding of the impact of childhood adversity across young adulthood.

Abstract
Youth with legal system involvement are especially likely to experience parental harshness (PH) and exposure to community violence (ETV), two common forms of life stress. However, most studies examine these stressors separately or collapse across them in ways that preclude examination of their co-occurrence. Consequently, it is unclear 1) how PH and ETV simultaneously fluctuate across development and 2) how these fluctuations predict future mental health problems in legal system-involved youth. We used group-based multi-trajectory modeling to estimate simultaneous trajectories of PH and ETV in 1027 legal system-involved youth and regression analyses to understand how trajectory membership predicted mental health problems three years later. Four trajectories of co-occurrence were identified (1: Low; 2: Moderate and Decreasing; 3: Moderate PH/High ETV; 4: High PH/Moderate ETV). Compared to the Low trajectory, all trajectories with PH/ETV elevations predicted violent crime and substance problems; trajectory 3 (Moderate PH/High ETV) predicted nonviolent crime and depression/anxiety symptoms; trajectory 4 (High PH/Moderate ETV) predicted depression diagnosis. These results elucidate how PH and ETV typically co-occur across adolescence for legal system-involved youth. They also reveal important commonalities and dissociations among types of mental health problems.

Abstract
The widely acknowledged detrimental impact of early adversity on child development has driven efforts to understand the underlying mechanisms that may mediate these effects within the developing brain. Recent efforts have begun to move beyond associating adversity with the morphology of individual brain regions towards determining if and how adversity might shape their interconnectivity. However, whether adversity effects a global shift in the organisation of whole-brain networks remains unclear. In this study, we assessed this possibility using parental questionnaire and diffusion imaging data from The Avon Longitudinal Study of Parents and Children (ALSPAC, N = 913), a prospective longitudinal study spanning more than 20 years. We tested whether a wide range of adversities-including experiences of abuse, domestic violence, physical and emotional cruelty, poverty, neglect, and parental separation-measured by questionnaire within the first seven years of life were significantly associated with the tractography-derived connectome in young adulthood. We tested this across multiple measures of organisation and using a computational model that simulated the wiring economy of the brain. We found no significant relationships between early exposure to any form of adversity and the global organisation of the structural connectome in young adulthood. We did detect local differences in the medial prefrontal cortex, as well as an association between weaker brain wiring constraints and greater externalising behaviour in adolescence. Our results indicate that further efforts are necessary to delimit the magnitude and functional implications of adversity-related differences in connectomic organization. RESEARCH HIGHLIGHTS: Diverse prospective measures of the early-life environment do not predict the organisation of the DTI tractography-derived connectome in young adulthood Wiring economy of the connectome is weakly associated with externalising in adolescence, but not internalising or cognitive ability Further work is needed to establish the scope and significance of global adversity-related differences in the structural connectome.

Abstract
The life course perspective and cumulative inequality theory suggest that childhood adversity, occurring during a sensitive period of the life course, can have long-term consequences for adult mental health and well-being. Yet, the long-term influence of adversity on adult outcomes may depend on both the features of adverse childhood experiences (e.g., the number, type, and co-occurrence of adversities) as well as the outcome assessed. Using latent class analysis applied to several waves of prospective data from the Great Smoky Mountain Study (GSMS; N=1,420) we identify subpopulations that are similar in their adversity experiences before age 18. We then predict adult internalizing and substance use disorder diagnoses by adversity experience. Results reveal five distinct classes of adversity, with unique risks for specific diagnoses in adulthood.

Abstract
OBJECTIVE To test whether childhood mental health symptoms, substance use, and early adversity accelerate the rate of DNA methylation (DNAm) aging from adolescence to adulthood. METHOD DNAm was assayed from blood samples in 381 participants in both adolescence (mean [SD] age = 13.9 [1.6] years) and adulthood (mean [SD] age = 25.9 [2.7] years). Structured diagnostic interviews were completed with participants and their parents at multiple childhood observations (1,950 total) to assess symptoms of common mental health disorders (attention-deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, anxiety, and depression) and common types of substance use (alcohol, cannabis, nicotine) and early adversities. RESULTS Neither childhood mental health symptoms nor substance use variables were associated with DNAm aging cross-sectionally. In contrast, the following mental health symptoms and substance variables were associated with accelerated DNAm aging from adolescence to adulthood: depressive symptoms (b = 0.314, SE = 0.127, p = .014), internalizing symptoms (b = 0.108, SE = 0.049, p = .029), weekly cannabis use (b =1.665, SE = 0.591, p = .005), and years of weekly cannabis use (b = 0.718, SE = 0.283, p = .012). In models testing all individual variables simultaneously, the combined effect of the variables was equivalent to a potential difference of 3.17 to 3.76 years in DNAm aging. A final model tested a variable assessing cumulative exposure to mental health symptoms, substance use, and early adversities. This cumulative variable was strongly associated with accelerated aging (b = 0.126, SE = 0.044, p = .005). CONCLUSION Mental health symptoms and substance use accelerated DNAm aging into adulthood in a manner consistent with a shared risk mechanism.

Abstract
Background Adverse early-life experiences (ELA), including poverty, trauma and neglect, affect a majority of the world's children. Whereas the impact of ELA on cognitive and emotional health throughout the lifespan is well-established, it is not clear how distinct types of ELA influence child development, and there are no tools to predict for an individual child their vulnerability or resilience to the consequences of ELAs. Epigenetic markers including DNA-methylation profiles of peripheral cells may encode ELA and provide a predictive outcome marker. However, the rapid dynamic changes in DNA methylation in childhood and the inter-individual variance of the human genome pose barriers to identifying profiles predicting outcomes of ELA exposure. Here, we examined the relation of several dimensions of ELA to changes of DNA methylation, using a longitudinal within-subject design and a high threshold for methylation changes in the hope of mitigating the above challenges. Methods We analyzed DNA methylation in buccal swab samples collected twice for each of 110 infants: neonatally and at 12 months. We identified CpGs differentially methylated across time, calculated methylation changes for each child, and determined whether several indicators of ELA associated with changes of DNA methylation for individual infants. We then correlated select dimensions of ELA with methylation changes as well as with measures of executive function at age 5 years. We examined for sex differences, and derived a sex-dependent 'impact score' based on sites that most contributed to the methylation changes. Findings Setting a high threshold for methylation changes, we discovered that changes in methylation between two samples of an individual child reflected age-related trends towards augmented methylation, and also correlated with executive function years later. Among the tested factors and ELA dimensions, including income to needs ratios, maternal sensitivity, body mass index and sex, unpredictability of parental and household signals was the strongest predictor of executive function. In girls, an interaction was observed between a measure of high early-life unpredictability and methylation changes, in presaging executive function. Interpretation These findings establish longitudinal, within-subject changes in methylation profiles as a signature of some types of ELA in an individual child. Notably, such changes are detectable beyond the age-associated DNA methylation dynamics. Future studies are required to determine if the methylation profile changes identified here provide a predictive marker of vulnerabilities to poorer cognitive and emotional outcomes.

Abstract
Exposure to early life adversity (ELA) is associated with increased externalizing symptoms (e.g., aggression and oppositionality), internalizing symptoms (e.g., withdrawal and anxiety), and biological indicators of accelerated aging (e.g., telomere length) in childhood. However, little is known about how distinct dimensions of ELA, such as threat and deprivation, impact youth psychobiological outcomes. The present study includes data from the Future of Families and Child Wellbeing Study (FFCWS), a large population-based, birth cohort study of majority (approximately 75%) racial and ethnic minority youth born between 1998 and 2000 across 20 large cities in the United States. The present study includes a subset of the original sample (N = 2,483, 51.6% male) who provided genetic data at age 9. First, confirmatory factor analyses were conducted, which revealed four distinct dimensions of ELA (home threat, community threat, neglect, and lack of stimulation) when children were age 3. Second, latent profile analyses identified an eight-profile solution based on unique patterns of the four ELA dimensions. Lastly, latent profiles were used to predict associations with child psychological and biological outcomes at age 9. Results suggest that exposure to specific combinations of ELA is differentially associated with internalizing and externalizing behaviors in childhood, but not with telomere length. Findings have implications for personalized early intervention and prevention efforts aimed at reducing ELA exposure to protect against downstream negative mental health outcomes for diverse youth.

Abstract
Key theoretical frameworks have proposed that examining the impact of exposure to specific dimensions of stress at specific developmental periods is likely to yield important insight into processes of risk and resilience. Utilizing a sample of N = 549 young adults who provided a detailed retrospective history of their lifetime exposure to numerous dimensions of traumatic stress and ratings of their current trauma-related symptomatology via completion of an online survey, here we test whether an individual's perception of their lifetime stress as either controllable or predictable buffered the impact of exposure on trauma-related symptomatology assessed in adulthood. Further, we tested whether this moderation effect differed when evaluated in the context of early childhood, middle childhood, adolescence, and young adulthood stress. Consistent with hypotheses, results highlight both stressor controllability and stressor predictability as buffering the impact of traumatic stress exposure on trauma-related symptomatology and suggest that the potency of this buffering effect varies across unique developmental periods. Leveraging dimensional ratings of lifetime stress exposure to probe heterogeneity in outcomes following stress - and, critically, considering interactions between dimensions of exposure and the developmental period when stress occurred - is likely to yield increased understanding of risk and resilience following traumatic stress.

Abstract
Executive function (EF) describes a group of cognitive processes underlying the organization and control of goal-directed behaviour. Environmental experience appears to play a crucial role in EF development, with early psychosocial deprivation often linked to EF impairment. However, many questions remain concerning the developmental trajectories of EF after exposure to deprivation, especially concerning specific mechanisms. Accordingly, using an 'A-not-B' paradigm and a macaque model of early psychosocial deprivation, we investigated how early deprivation influences EF development longitudinally from adolescence into early adulthood. The contribution of working memory and inhibitory control mechanisms were examined specifically via the fitting of a computational model of decision making to the choice behaviour of each individual. As predicted, peer-reared animals (i.e. those exposed to early psychosocial deprivation) performed worse than mother-reared animals across time, with the fitted model parameters yielding novel insights into the functional decomposition of group-level EF differences underlying task performance. Results indicated differential trajectories of inhibitory control and working memory development in the two groups. Such findings not only extend our knowledge of how early deprivation influences EF longitudinally, but also provide support for the utility of computational modelling to elucidate specific mechanisms linking early psychosocial deprivation to long-term poor outcomes.

Empirically-derived dimensions of childhood adversity and cumulative risk: associations with measures of depression, anxiety, and psychosis-spectrum psychopathology. Eur J Psychotraumatol 2023; 14:2222614. [PMID: 37377079 DOI: 10.1080/20008066.2023.2222614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 04/30/2023] [Accepted: 05/25/2023] [Indexed: 06/29/2023] Open
Abstract
Background: Investigating different approaches to operationalizing childhood adversity and how they relate to transdiagnostic psychopathology is relevant to advance research on mechanistic processes and to inform intervention efforts. To our knowledge, previous studies have not used questionnaire and interview measures of childhood adversity to examine factor-analytic and cumulative-risk approaches in a complementary manner.Objective: The first aim of this study was to identify the dimensions underlying multiple subscales from three well-established childhood adversity measures (the Childhood Trauma Questionnaire, the Childhood Experience of Care and Abuse Interview, and the Interview for Traumatic Events in Childhood) and to create a cumulative risk index based on the resulting dimensions. The second aim of the study was to examine the childhood adversity dimensions and the cumulative risk index as predictors of measures of depression, anxiety, and psychosis-spectrum psychopathology.Method: Participants were 214 nonclinically ascertained young adults who were administered questionnaire and interview measures of depression, anxiety, psychosis-spectrum phenomena, and childhood adversity.Results: Four childhood adversity dimensions were identified that captured experiences in the domains of Intrafamilial Adversity, Deprivation, Threat, and Sexual Abuse. As hypothesized, the adversity dimensions demonstrated some specificity in their associations with psychopathology symptoms. Deprivation was uniquely associated with the negative symptom dimension of psychosis (negative schizotypy and schizoid symptoms), Intrafamilial Adversity with schizotypal symptoms, and Threat with depression, anxiety, and psychosis-spectrum symptoms. No associations were found with the Sexual Abuse dimension. Finally, the cumulative risk index was associated with all the outcome measures.Conclusions: The findings support the use of both the empirically-derived adversity dimensions and the cumulative risk index and suggest that these approaches may facilitate different research objectives. This study contributes to our understanding of the complexity of childhood adversity and its links to different expressions of psychopathology.

Abstract
Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of mortality and is often associated with serious disability and depression. Little is known about the characteristics of those who are in complete mental health (CMH) despite having COPD. This study’s objectives are to: (1) estimate the prevalence and odds of absence of psychiatric disorders (APD) and CMH among older adults that reported having COPD, compared to their peers that did not; (2) identify factors associated with APD and with CMH. Bivariate and logistic regression analyses were conducted using the nationally representative Canadian Community Health Survey—Mental Health. The results indicate that there was a significantly (p < 0.001) lower prevalence of APD (86.7% vs. 95.0%) and CMH (66.7% vs. 77.0%) among older adults aged 50+ with COPD (n = 703) compared to those without COPD (n = 10,189). Half of the sample was female (50.5%) and the majority of whom were under age 70 (62.5%). Factors significantly (p < 0.05) associated with higher odds of APD and of CMH among older adults with COPD include being married, having a confidant, being physically active, and having no lifetime history of major depressive disorder or generalized anxiety disorder. For every additional adverse childhood experience, the odds of APD declined by 31%. The majority of those with COPD are mentally flourishing despite having this disabling and life-threatening disorder. These findings underline the importance of targeted interventions and outreach to those most vulnerable to poorer mental health outcomes including the socially isolated.

Abstract
We investigated the conceptualization and impact of adverse childhood experiences (ACEs) in a sample of 231 children ages 3-5 living in poverty and experiencing homelessness, focusing specifically on caregiver well-being and housing instability. Data was collected using the Neurodevelopmental Ecological Screening Tool (NEST), which screens for developmental risk and resilience across three domains (neurodevelopmental, caregiver, and environment). We used structural equation modelling (SEM) to test the association between domains and ACE scores and assessed the impact on neurodevelopmental constructs. Fifty-five percent of the sample had high ACE scores (> 3), which were associated with lower attention, social skills, and emotional regulation. ACEs were strongly associated with 0.17 standard deviation units of higher levels of caregiver distress (p < .001), which was also associated with 0.26 standard deviation units of lower levels of child neurodevelopmental functioning (p = .001). For each unit increase in housing instability, there was a three-fourths increase in ACE (0.78 ACE at p = .004); four or more moves were associated with the worst neurodevelopmental outcomes (53% of the sample). We must use an ecological, developmental lens to understand how early adversity impacts children, at what age, and in what context. Housing stability plays a critical role in developmental well-being and should be accounted for in conceptualizations of child ACE scales. Caregiver and child relationships are reciprocal, and so the impacts of ACEs are also bidirectional. Our policies and practices at individual, community, and systemic levels should account for these dynamics to improve child well-being.

Abstract
BACKGROUND Recent studies in both human and experimental animals have identified fragmented and unpredictable parental and environmental signals as a novel source of early-life adversity. Early-life unpredictability may be a fundamental developmental factor that impacts brain development, including reward and emotional memory circuits, affecting the risk for psychopathology later in life. Here, we tested the hypothesis that self-reported early-life unpredictability is associated with psychiatric symptoms in adult clinical populations. METHODS Using the newly validated Questionnaire of Unpredictability in Childhood, we assessed early-life unpredictability in 156 trauma-exposed adults, of which 65% sought treatment for mood, anxiety, and/or posttraumatic stress disorder (PTSD) symptoms. All participants completed symptom measures of PTSD, depression and anhedonia, anxiety, alcohol use, and chronic pain. Relative contributions of early-life unpredictability versus childhood trauma and associations with longitudinal outcomes over a 6-month period were determined. RESULTS Early-life unpredictability, independent of childhood trauma, was significantly associated with higher depression, anxiety symptoms, and anhedonia, and was related to higher overall symptom ratings across time. Early-life unpredictability was also associated with suicidal ideation, but not alcohol use or pain symptoms. CONCLUSIONS Early-life unpredictability is an independent and consistent predictor of specific adult psychiatric symptoms, providing impetus for studying mechanisms of its effects on the developing brain that promote risk for psychopathology.

Abstract
Emerging evidence suggests that partially distinct mechanisms may underlie the association between different dimensions of early life adversity (ELA) and psychopathology in children and adolescents. While there is minimal evidence that different types of ELA are associated with specific psychopathology outcomes, there are partially unique cognitive and socioemotional consequences of specific dimensions of ELA that increase transdiagnostic risk of mental health problems across the internalizing and externalizing spectra. The current review provides an overview of recent findings examining the cognitive (e.g., language, executive function), socioemotional (e.g., attention bias, emotion regulation), and mental health correlates of ELA along the dimensions of threat/harshness, deprivation, and unpredictability. We underscore similarities and differences in the mechanisms connecting different dimensions of ELA to particular mental health outcomes, and identify gaps and future directions that may help to clarify inconsistencies in the literature. This review focuses on childhood and adolescence, periods of exquisite neurobiological change and sensitivity to the environment. The utility of dimensional models of ELA in better understanding the mechanistic pathways towards the expression of psychopathology is discussed, with the review supporting the value of such models in better understanding the developmental sequelae associated with ELA. Integration of dimensional models of ELA with existing models focused on psychiatric classification and biobehavioral mechanisms may advance our understanding of the etiology, phenomenology, and treatment of mental health difficulties in children and youth.
