Paternal adverse childhood experiences are associated with a low risk of atopy in the offspring.

Parental adverse childhood experiences (ACE) might affect the offspring health through intergenerational inheritance. The aim of this study was to investigate how paternal ACE associate with offspring sensitisation and allergic rhinitis (AR). The study included 590 Finnish father-child dyads from the FinnBrain Birth Cohort Study. Outcomes were offspring sensitisation against allergens and AR at age 5.5 years. Paternal ACE up to 18 years were assessed using the Trauma and Distress Scale (TADS) with the lowest quarter as the reference group. Of the children, 317 (54%) were males. Sensitisation occurred in 162/533 (30%) and AR in 122/590 (21%). Paternal TADS (median 17 points; interquartile range 11-27) was inversely associated with the risk of sensitisation. Children whose fathers scored the highest quarter had the lowest risk of sensitisation (adjusted odds ratio 0.42; 95% confidence interval 0.24-0.75), followed by those in the second highest quarter (0.58; 0.34-0.99). The association between the highest quarter and reduced risk of AR was similar. Paternal ACE were associated with a low risk of offspring sensitisation and AR, suggesting paternal childhood stress might influence immune responses in their offspring.

Association of adverse childhood experiences with adult-onset cardiometabolic conditions and prescription medicine use

Abstract Association of adverse childhood experiences with adult-onset cardiometabolic conditions and prescription medicine use Background and importance Adverse childhood experiences are potentially preventable and traumatic events that occur during childhood. Childhood exposure to trauma is highly prevalent and adults who had adverse childhood experiences are at increased risk of developing physical conditions. However, effect of adverse childhood experiences on health outcomes remains underrecognized. Aim Here, we aimed to measure the association of cumulative adverse childhood experience with adult physical condition and use of prescription medicines in general population. Methods We conducted a cross-sectional analysis using the population-based health study including 21083 participants at age 40 years or older. Self-reported adverse childhood experiences before age at 18 years, present or previous cardiometabolic conditions, and present or previous use of medications prescribed for cardiometabolic conditions were used in our analysis. Cox proportional hazards regression was used to estimate age, sex, smoking, education, and income-adjusted risk of cardiometabolic condition and prescription medicine use after adverse childhood experiences. Association of multimorbidity and using multiple prescription medicines with adverse childhood experience was analyzed using generalized linear model with ordinal classification. Results We found that having a history of adverse childhood experience was associated with increased risk of subsequent cardiometabolic conditions; hazard ratios ranged from 1.117 (95% CI, 1.054 – 1.185) to 1.341 (95% CI, 1.181 – 1.522). Furthermore, adverse childhood experience was associated with multimorbidity of cardiometabolic conditions (odds ratio [OR], 1.195; 95% CI, 1.117 – 1.279) and increased risk of using multiple prescription medicines (OR, 1.131; 95% CI, 1.057 – 1.210). Notably, we observed the dose – effect relationships of cumulative adverse childhood experience to the increased risk of 5 among 6 cardiometabolic conditions and to the increased risk of using 4 among 6 prescription medicines. Furthermore, cumulative adverse childhood experience had the dose – effect associations with multimorbidity of cardiometabolic conditions (ORs ranged from 1.120 [95% CI, 1.033 – 1.214] to 1.526 [95% CI, 1.276 – 1.825]) and using multiple prescription medicines (ORs are 1.393 [95% CI, 1.195 – 1.624] and 1.572 [95% CI 1.315 1.879]). Conclusions and relevance: Our findings implicate cumulative adverse childhood experience as a risk factor for later cardiometabolic conditions and use of medicines prescribed for cardiometabolic conditions. Our results are significant by suggesting inquiry into adverse childhood experience exposure during clinical consultations, services to alleviate the burden and increasing resilience in addition to strategies aimed at prevention of cardiometabolic conditions might improve health outcomes.

Prevalence of Adverse Childhood Experiences Among Adolescents.

Adverse childhood experiences (ACEs) are preventable, potentially traumatic events with lifelong negative impacts. Population-level data on ACEs among adolescents have historically relied on parent reports and excluded abuse-related ACEs. We present the self-reported prevalence of ACEs among a large population-based sample of US high school students. Using cross-sectional, state-representative data from 16 states that included core ACE questions on their 2021 Youth Risk Behavior Survey, we estimate the prevalence of 8 individual (lifetime emotional, physical, or sexual abuse, physical neglect, witnessed intimate partner violence, household substance use, household poor mental health, incarcerated parent or guardian) and cumulative ACEs (0, 1, 2-3, ≥4) among a large population-based sample of adolescents, overall and by demographic characteristics (sex, race and ethnicity, age, sexual orientation). Emotional abuse (65.8%), household poor mental health (36.1%), and physical abuse (32.5%) had the highest prevalence. ACEs were very common, with 80.5% of adolescents experiencing at least 1 ACE and 22.4% experiencing ≥4 ACEs. Experiencing ≥4 ACEs was highest among adolescents who were female (27.7%), non-Hispanic multiracial (33.7%), non-Hispanic American Indian or Alaska Native (27.1%), gay or lesbian (36.5%), bisexual (42.1%), or who described their sexual identity some other way or were not sure of their sexual identity (questioning) (36.5%). Self-reported ACE estimates among adolescents exceed previously published parent-reported estimates. ACEs are not equally distributed, with important differences in individual and cumulative ACEs by demographic characteristics. Collecting ACE data directly from adolescents at the state level provides actionable data for prevention and mitigation.

Adverse childhood experiences and age-trajectories of depressive symptom for middle and older ages

Abstract Background Adverse childhood experiences (ACEs) have lifelong impacts on health outcomes. Less is known about their effects on later outcomes (mental health). Moreover, associations of ACEs with age-trajectories of depressive symptoms and how they differ in different countries remain unclear. We investigated associations between ACEs and trajectories of depressive symptoms at mid-to-older ages in two distinct populations. Methods We used longitudinal data from English Longitudinal Study of Ageing (ELSA: n = 19602, ≥50y) and China Health and Retirement Longitudinal Study (CHARLS: n = 19561, ≥45y). Depressive symptoms were measured by Center for Epidemiologic Studies Depression scale at 10 waves (2002-2022) in ELSA and at 5 waves (2011-2020) in CHARLS. ACEs were retrospectively reported in both studies. We applied group-based trajectory modelling to identify distinct age-trajectories of depressive symptoms and multinomial regression to estimate associations between ACEs and trajectory groups. Results We identified three trajectory groups: in ELSA: high (12.3% in men and 14.7% in women), moderate (46.6% and 47.9%) and low (41.1% and 37.4%), and in CHARLS: high (9.3% and 13.2%), moderate (34.1% and 39.4%) and low (56.6% and 47.4%). Most ACEs were associated with increased risk of having moderate/ high trajectories of depressive symptoms after adjusting for other ACEs, sex, and childhood socioeconomic disadvantages. For example, for physical abuse, the adjusted relative risk ratio (RRRadj) for high and moderate trajectory groups was 2.09(1.99, 2.19) and 1.16(1.12, 1.20) respectively in ELSA. It was 1.34(1.23, 1.44) and 1.22(1.13, 1.32) in CHARLS. For domestic violence, the respective RRRadj was 1.90(1.65, 2.18) and 1.44(1.22, 1.70) in ELSA, and 1.33(1.22, 1.44) and 1.24(1.14, 1.35) in CHARLS. Conclusions ACEs have life-long effects on mental health at mid-to-older ages in both countries, highlighting the need of early intervention to improve mental health in later life. Key messages • Our work considered the distinct patterns of age-trajectories of depressive symptoms for adults at middle and older ages, capturing the changing process of mental health problems in later life. • We also investigated the associations between childhood factors and trajectory of depressive symptoms, which helped to improve mental health for older people under the situation of global ageing.

Impact of Adverse Childhood Experiences on Child Development in South America: A Systematic Review

Abstract Background Adverse Childhood Experiences (ACEs) have garnered attention globally for their detrimental effects on children’s development, such as lower communication, gross and fine motor, and personal-social domains. While extensively studied in high-income countries, there remains a gap in understanding their prevalence and impact in low- and middle-income countries (LMICs). This review aimed to identify, evaluate, and summarize the findings of an association between ACEs and children’s developmental and mental health outcomes in South America Methods A systematic review was conducted to investigate the association between ACEs and childhood development in South America. Databases MEDLINE, PsycINFO, Web of Science, Applied Social Sciences Index and Abstracts, Literatura Latino Americana em Ciências da Saúde, IBECS and CINAHL were searched. Selection criteria encompassed studies from Brazil, Colombia, Argentina, Peru, Venezuela, Chile, Ecuador, Bolivia, Paraguay, Uruguay, Guyana and Suriname examining the effects of ACEs on developmental outcomes and mental health disorders in children under 18 years old. Quality assessment aligned with World Health Organization standards was employed. Results Twenty-four studies met the inclusion criteria, with most categorized as low or very low quality. While the majority demonstrated a significant association between ACEs and developmental or mental health outcomes, a few studies reported null findings. Challenges in study quality, such as small sample sizes and selection bias, were identified. Conclusions Despite limitations in study quality, findings underscore the impact of ACEs on child development and mental health in South America. Because of the low quality of the existent studies the next steps should be to grasp a greater understanding of the issue. This review also highlights the urgency for further research and targeted interventions to mitigate the long-term consequences of ACEs in this region. Key messages • ACEs profoundly affect child development and mental health in South America, necessitating urgent attention and intervention. • Addressing the impact of ACEs in South America is critical for fostering healthier developmental trajectories and enhancing public health outcomes.

Early life social predictors of longitudinal relations between childhood BMI and overeating

Abstract Introduction The progression of obesity is a continuous process involving a complex system of genetic, environmental, and behavioural factors. Socioeconomic disadvantage as well as psychological distress may lead to overeating, subsequently associated with increased energy intake and weight gain. Recent evidence indicated that the association between childhood obesity and overeating might be bidirectional. Therefore, this study aimed to longitudinally investigate the directionality of the association between childhood BMI and overeating and to identify antecedent early childhood predictors. Methods The study sample included 5,777 children from the European Longitudinal Study of Parents and Children (ELSPAC), collected between 18 months and 11 years of child age. The outcomes were child BMI and overeating. Predictors included maternal BMI, maternal education, single-parent households, financial difficulties, and adverse childhood experiences (ACEs). The random intercept cross-lagged panel model (RI-CLPM) was applied. Results The results showed temporal stability in the development of overeating and BMI, with a bidirectional relationship that strengthened over time. The child’s BMI was predicted by maternal BMI (β = 0.37, p < 0.001). The child’s overeating was predicted by maternal BMI (β = 0.13, p < 0.001), but a stronger effect was found for ACEs (β = 0.24, p < 0.001). ACEs mediated the impact of maternal education, financial difficulties, and single parenthood on overeating with indirect effects of β = -0.01 (p = 0.005), β = 0.04, (p < 0.001), and β = 0.07 (p < 0.001), respectively. Conclusions We observed stable bidirectional longitudinal effects, with a stronger association from BMI to overeating. The results suggested two main pathways: one linked to maternal BMI and early childhood BMI increase followed by overeating, and the other associated with ACEs mediating the effect of early childhood socioeconomic factors on overeating, leading to gradual BMI gain. #NGEU Key messages • The study revealed a stable bidirectional association between childhood BMI and overeating, with a stronger association from BMI to overeating. • There are two potential pathways in childhood obesity development, one involving maternal BMI, and the second associated with social disadvantage and ACEs.

Transforming systems and improving lives - the social movement of compassion in Wales

Abstract Wales has embarked on a journey towards becoming an adverse childhood experiences (ACEs) and trauma-informed nation. In 2021 the Welsh government supported the co-creation and co-production of an all age, all of society framework: Trauma- Informed Wales: A Societal Approach to Understanding, Preventing and Supporting the Impacts of Trauma and Adversity (ACE Hub Wales et al 2021). This framework is not just an operating model, it has the ambition to be a social movement to embed and sustain a culture shift that is rooted in tackling the conditions of inequality in our communities and the work we do in organisations in the clinical and community settings that support, and employ, people who have experienced trauma and adversity in their lives. The starting point is that any of us can have these experiences. The trauma and ace informed toolkit sets out a process of readiness, self assessment, action planning and implementation across six domain areas which include governance and leadership, monitoring and evaluation, policy and practice. Resources and guidance are co-created and co-produced by partners already on the journey, developed and tested in environments to look at trauma-informed physical spaces, communications, workforce development, training and inclusion of marginalised voices. Supporting this work is a national community of practice, promoting good practice, sharing ideas and developing a culture of wisdom supported by reflective practice. This dynamic forum is supported by online and in person capacity and is transforming organisations and sectors including housing, education, substance misuse, criminal justice and health. It places people, compassion, kindness and empathy at the heart and is enabling traumatised systems to understand and meet the needs of the workforce and the people they serve. Key messages • Systems change is sustained by compassion, kindness and love in a social movement supported by the scaffolding of an operating model. • Public Health has a key role to play in co-developing social networks and resources to transform traumatised systems into trauma-informed places that improve lives and health outcomes.

Predictors and outcomes of adolescent alcohol and drug use: a scoping review

Abstract Background Adolescence is a pivotal life stage marked by educational advancement, entry into the workforce and formation of lasting relationships. Globally, adolescence is also the peak period during which individuals first engage in alcohol and/or drug consumption. This scoping review aimed to summarize existing longitudinal research on factors and outcomes related to adolescent substance use to identify gaps in existing evidence. Methods A scoping review was conducted in accordance with the PRISMA extension for scoping reviews. A systematic literature search was conducted on PubMed. Additional studies were identified through hand-searching key reference lists and Google Scholar searches. A narrative synthesis was completed. Results 123 studies were included; 12 reviews and 111 cohort studies. 60% of cohort studies originated from North America, 29% Europe, 7% Australia/New Zealand, 2% South America and 2% Asia. Factors consistently associated with increased risk of ASU include male sex, increasing age, externalizing disorders, adverse childhood experiences and peer or parental substance use. Few studies considered wider community or neighbourhood factors. Early initiation and higher frequency of adolescent drug use were predictive of later-life substance use patterns, education derailment, contact with the justice system and mental health disorders. Conclusions The body of longitudinal evidence on adolescent substance use is rapidly expanding yet significant research gaps exist. Rising levels of cocaine use and its substantial health impacts motivate further research on all potentially important factors associated with cocaine use to guide interventions for prevention and treatment. Key messages • There are important gaps in existing research on adolescent substance use. • These include neighbourhood influences and factors associated with initiation of illicit drugs other than cannabis.

Shifting focus - the need to prioritise an inclusive public health approach to trauma

Abstract Since 2017, the Welsh government has prioritised the development of a Public Health Approach to understanding the impact of Adverse Childhood Experiences. Taking the work of Bellis et al, and the population level research to understand the prevalence of ACEs, and associated risks (Bellis etc al, 2015), the ACE Hub Wales was established to coordinate a multi-agency, cross sector approach to preventing, tackling and mitigating the impact of adversity in childhood. The Hub developed its approach to advocate for more public awareness of the life course risks to health if the right support was not accessed or available to children, such as poor mental health and chronic conditions such as type 2 diabetes and heart disease in adulthood. From 2021 there has been a dramatic shift to attempting to understand the experiences, and unmet needs, of children and people who have come to Wales to seek sanctuary, migrant women who have no recourse to public funds, and people experiencing racism and discrimination. In 2021, the ACE Hub Wales co-produced a Wales national trauma-informed practice framework including a set of principles placing inclusion at the heart of the approach in Wales; shining a light on the need to have a cultural, intergenerational and gender-based understanding of adversity and trauma which links directly to, informs and supports the government’s ambitions to be a nation of sanctuary and to be anti racist by 2030. To continue to ignore the experiences of adversity and trauma by people of colour, and Gypsy, Roma and Traveller people; is to perpetuate the health inequity experienced in healthcare, and justice systems. Wales has committed to developing wisdom, not just knowledge, that means that a public health approach is inclusive of all of our communities in Wales. Key messages • The experiences of racialised ad minoritised communities from population studies of adversity and trauma is traumatizing. • Understanding the life course impact of adversity and trauma must include the experiences of racism and discrimination to be inclusive and trauma-informed.

Heritable heart failure traits in mice undergoing early life stress

Abstract Introduction Adverse childhood experiences, known as early life stress (ELS), are associated with increased cardiovascular disease risk in later life, yet the underlying mechanisms remain elusive. Recent evidence indicates that parental life experiences can be transmitted to the offspring. Whether ELS exerts transgenerational effects on the heart is unknown. Purpose To investigate the effects of ELS on cardiac structure and function in exposed parents and in their offspring, across 3 generations. Methods We used a mouse model of ELS (MSUS) that mimics the exposure to traumatic experiences during childhood in humans. Mouse pups (F1) were separated from their mother (F0) unpredictably each day for 3 hours from postnatal day 1 (PND1) to PND14. During separation, dams were exposed to an additional unpredictable stressor by being subjected to either, a forced swim (18°C water for 5 minutes) or a 20-minute physical tube restraint, anytime (unpredictably) during the 3 hours. From PND15, mice are left undisturbed with their mother until PND21, are then raised normally until adulthood. Control litters were raised normally. A high-resolution Micro-Ultrasound System (Vevo 3100, Visualsonics) was used for the echocardiographic assessment at 6, 12 and 18 months both in the exposed animals (F0) as well as in their offspring (F1) and grandoffspring (F2). Both male and female mice were studied. Heart weight/tibia length and left ventricle weight/tibia length were used to assess cardiac mass while myocardial fibrosis was assessed by Masson's Trichrome and Picriosirius Red stainings. Lung congestion was assessed as lung wet/dry weight ratio. Single cell RNA sequencing (scRNAseq) was used in LV specimens from MSUS mice to unveil cell-specific transcriptional changes. Finally, MSUS mice underwent environmental enrichment (cages containing running wheels, maze) to investigate any rescuing effect on cardiac function. Results F1 mice displayed increased LV mass, impaired diastolic function, myocardial fibrosis and lung congestion. A time-dependent worsening of cardiac performance was observed from 6 to 18 months, both in males and females. ScRNAseq unveiled dysregulation of transcriptional programs underlying inflammation and lipotoxicity in the cardiomyocyte and endothelial cell clusters. The MSUS offspring did not show changes of cardiac function at 6 months, however diastolic dysfunction and lung congestion were observed at 12 and 18 months. A similar impairment of cardiac function was observed in the MSUS grandoffspring (F3). Of interest, 6-week exposure to an environmental enrichment protocol was able to improve LV mass, diastolic function and lung congestion in 12 months-old MSUS mice. Conclusions ELS induces a transgenerational transmission of cardiac phenotypic alterations which can be rescued by EE. Our results shed light on the potential role of ELS on heart failure development and potential mitigation strategies.

Associations Between Adverse Childhood Experiences, Adolescent Behavioral Health Challenges, and High School Dropout.

Adverse childhood experiences (ACEs) are associated with behavioral health challenges and high school dropout, and behavioral health is associated with high school dropout. Less is known about the role of behavioral health challenges in the relationship between ACEs and high school dropout. Using data from the Panel Study of Income Dynamics (2013) and its 2014 Childhood Retrospective Circumstances Study supplement, the current study conducts mediational path analysis to examine the direct and indirect effects of cumulative ACEs on high school dropout via adolescent depression, anxiety, and substance use. Experiencing more ACEs was associated with depression, anxiety, and substance use. Only depression and substance use were associated with high school dropout. There was a significant direct effect between increased ACEs and high school dropout and significant indirect effects via depression and substance use, but not anxiety. Adolescent behavioral health interventions to address the long-term effects of ACEs may also support academic achievement. School-based interventions, particularly those aligned with trauma-sensitive school frameworks and engaging various school personnel, including school nurses, should be considered. Community- and policy-level interventions aimed at primary prevention of ACEs are also needed.

Real-world predictors of severe psychological distress during the COVID-19 pandemic in Japan: Insights from a large-scale internet-based cohort study.

The COVID-19 pandemic has had negative physical and psychological impacts worldwide. However, there has been a lack of real-world evidence concerning the predictors of severe psychological distress (SPD) among the general population in Japan during the COVID-19 pandemic. The aim of this study was to examine predictors of SPD during the COVID-19 pandemic. We investigated the predictors of new-onset SPD in the general Japanese population using data from a large-scale internet-based cohort study. We included 16 489 study participants (age range = 16-81, mean age = 52.7, percentage of male = 50%) in the analysis. Over the course of 1 year from baseline, the estimated proportion of participants who experienced SPD was 5.2% with inverse probability weighting. The predictors of SPD included younger age, being never married, being unemployed, having a higher education background, scoring higher on the Fear of Coronavirus-19 Scale, experiencing more adverse childhood experiences, reporting poorer subjective health status, and COVID-19 with oxygen therapy. Our internet-based survey of the Japanese population may have selection bias, limiting the generalizability to other countries and cultures. This study revealed that being afflicted with COVID-19 requiring oxygen therapy is the most significant predictor of SPD. In addition, we found that vulnerability to social isolation, such as never being unmarried, anxiety toward COVID-19, and susceptibility to stress, are predictors of the emergence of SPD. Therefore, the implementation of online support systems and ensuring access to accurate information may protect against SPD during the COVID-19 pandemic in Japan.

Internalizing Pathways to Adolescent Substance Use from Adverse Childhood Experiences

The mediating role of anxious, depressive, and somatic symptoms was examined in the association between adverse childhood experiences (ACEs) and adolescent substance use, with attention to the unique effects of each set of symptoms within the same model. Adolescents (n = 701) were assessed over time (ages 3–17) in a majority male (70.5%) and white (89.9%) sample. Findings indicate that depressive symptoms mediated the association between ACEs and adolescent cigarette and marijuana use. Although significant indirect effects remained when accounting for externalizing behavior, a novel protective pathway emerged through parent-reported youth anxiety and alcohol use. Assessing internalizing symptoms as separate facets within the same model is critical if we are to inform prevention programs that are tailored to the individual needs of youth who have experienced ACEs.

Trajectories and predictors of depressive symptoms among pregnant women: A 3-year longitudinal study.

Not all women experience the same changes in depression from pregnancy through the years following childbirth, but the patterns of prenatal and postnatal depression are underexplored. This study investigated the trajectories and associated predictors of depressive symptoms in women from pregnancy through the first 3 years postpartum. We followed 340 pregnant women from an antenatal clinic in Hong Kong, first at 20-24 weeks of gestation, then at 4 weeks after childbirth, and again at 3 years after childbirth. Pregnant women reported their depressive symptoms whether they had intimate partner violence, health conditions, adverse childhood experiences, family support, and perceived partner involvement. Latent class growth analysis was applied to identify distinct trajectories of depression, and binary logistic regressions were performed to analyze predictors of trajectories. We found that 26.5% of women showed clinical depressive symptoms at 20-24 weeks of gestation, 9.7% at 4 weeks after childbirth, and 12.6% at 3 years after childbirth. Two classes were identified: a low-stable group (86.2%) and a relapsing/remitting group (13.8%). Women with a history of trauma (i.e., intimate partner violence and adverse childhood experiences) and mental health difficulties were more likely to be classified in the relapsing/remitting group than in the low-stable group. Family support and partner emotional involvement appeared to protect the women from suffering relapsing/remitting depression. The findings highlight the importance of screening for depression throughout pregnancy and extending several years postpartum. Distinguishing the different trajectories of depression and identifying its associated factors are critical to providing targeted interventions to the most vulnerable women (i.e., a relapsing/remitting group in the present study).

The mediation role of gray matter volume in the relationship between childhood maltreatment and psychological resilience in adolescents with first-episode major depressive disorder

Previous studies have revealed morphologic alterations in patients with major depressive disorder (MDD) with experiences of childhood trauma. However, the underlying neural mechanisms remain largely unknown. This study aims to explore the brain structural changes and their possible mediation role in the relationship between childhood maltreatment and psychological resilience in drug-naïve adolescents with first-episode MDD. A total of 57 adolescents with first-episode MDD and 36 healthy controls (HCs) completed the T1-weighted magnetic resonance imaging scan. The adverse childhood experiences and current psychological resilience were assessed using the Childhood Trauma Questionnaire-Short Form and the Connor Davidson Resilience Scale, respectively. The voxel-based morphometry approach was applied to examine changes in the gray matter volume (GMV). Compared with the HCs, adolescents with MDD had significantly reduced GMV volumes in the left fusiform gyrus, right orbitofrontal gyrus, right superior temporal gyrus, right calcarine cortex, right middle frontal gyrus, left angular gyrus, right precuneus, right posterior cingulate gyrus, and right posterior central gyrus, as well as significantly increased GMV volumes in the left lenticular putamen and right lenticular pallidum. The GMV of the right calcarine cortex was found to be negatively correlated with the severity of emotional abuse and positively correlated with the level of psychological resilience. Moreover, the GMV of the right calcarine cortex might partially mediate the relationship between childhood maltreatment and psychological resilience. The present study provided further evidence for structural impairments in adolescents with MDD. Our findings also confirmed the important role of depression-related GMV changes in childhood growth experiences and psychological resilience characteristics during adolescent brain maturation.

Traumatic and Adverse Childhood Experiences and Developmental Differences in Psychiatric Risk

While adverse childhood experiences (ACEs) are known to impart significant risk for negative mental health and cognitive outcomes in youth, translation of ACE scores into clinical intervention is limited by poor specificity in predicting negative outcomes. This work expands on the ACE framework using a data-driven approach to identify 8 different forms of traumatic and adverse childhood experiences (TRACEs) and reveal their differential associations with psychiatric risk and cognition across development. Building upon the traditional ACEs model, this study aimed to characterize unique components of commonly co-occurring TRACEs and to examine moderation of longitudinal change in mental health and cognitive development during adolescence. This work draws from youth and their caregivers who completed up to 4 annual behavioral assessments from 2016 to 2021 as part of the ongoing Adolescent Brain Cognitive Development (ABCD) study. Data collection was performed at 21 regionally-distributed sites across the United States. Analyses for this work were conducted January 2023 through November 2023. Youth participants in the ABCD study's exposure to 268 different TRACEs, which were distilled into adversity components using nonlinear principal components analysis. Mixed-effects and latent change score models considered TRACEs components as moderators of longitudinal change in internalizing and externalizing mental health problems, as well as longitudinal change in cognitive ability. Data were distilled from 11 876 youth participants, who were grouped into dyads with a caregiver. ABCD study youth participants were 9 to 10 years old at baseline assessment (year 0) and 12 to 13 years old at ABCD year 3. A total of 5679 participants (47.8%) were female. Analyses revealed that TRACEs organized into 8 thematic adversity components (e.g., family conflict, interpersonal violence). At baseline assessment (year 0), exposure to nearly every adversity component was associated with poorer mental health and diminished cognitive ability. Yet across time, it was observed that different forms of adversity were variably linked to both increases and decreases in internalizing and externalizing problems. For example, while peer aggression (t = 5.31) and family conflict (t = 5.67) were associated with increases in both internalizing and externalizing problems over early adolescence, community threat (t = 2.82) and poverty (t = 2.07) were linked to decreased problems, potentially representing adaptive suppression of symptoms. Finally, adversity types related to resource deprivation (eg, poverty, caregiver maladjustment) were associated with declines in cognitive ability over early adolescence. In this cohort study, distinct forms of TRACEs differentially moderated developmental changes in psychiatric risk and cognitive ability in different ways, offering the possibility for precision-based prediction of risk for youth. Such findings could be used in targeted early prevention and intervention strategies for at-risk youth.

Social processes as the missing link: cross-sectionally testing a conceptual model on social mediators of early psychopathological development.

Research suggests that most mental health conditions have their onset in the critically social period of adolescence. Yet, we lack understanding of the potential social processes underlying early psychopathological development. We propose a conceptual model where daily-life social interactions and social skills form an intermediate link between known risk and protective factors (adverse childhood experiences, bullying, social support, maladaptive parenting) and psychopathology in adolescents - that is explored using cross-sectional data. N = 1913 Flemish adolescent participants (Mean age = 13.8; 63% girls) were assessed as part of the SIGMA study, a large-scale, accelerated longitudinal study of adolescent mental health and development. Self-report questionnaires (on risk/protective factors, social skills, and psychopathology) were completed during class time; daily-life social interactions were measured during a subsequent six-day experience-sampling period. Registered uncorrected multilevel linear regression results revealed significant associations between all risk/protective factors and psychopathology, between all risk/protective factors and social processes, and between all social processes and psychopathology. Social processes (social skills, quantity/quality of daily social interactions) were uniquely predicted by each risk/protective factor and were uniquely associated with both general and specific types of psychopathology. For older participants, some relationships between social processes and psychopathology were stronger. Unique associations between risk/protective factors and psychopathology signify the distinct relevance of these factors for youth mental health, whereas the broad associations with social processes support these processes as broad correlates. Results align with the idea of a social pathway toward early psychopathology, although follow-up longitudinal research is required to verify any mediation effect.

Exploring the Link Between Adverse Childhood Experiences and Adolescent Dating Violence Perpetration and Victimization: A Review of the Literature

Background and Purpose: Adverse childhood experiences (ACEs) have been linked with multiple adverse outcomes, including adolescent dating violence (ADV). ADV is a serious public health issue, with the U.S. rates ranging from 6.4% to 73% for victimization across all types and from 11% to 77% for perpetration. Given the high prevalence of ADV and the fact that it has been frequently linked with ACEs earlier in life, it is crucial to thoroughly understand this relation and apply this information to prevention and intervention efforts. However, to date, there are no known reviews synthesizing the link between ACEs and ADV, nor exploring which ACEs have been included across other studies. Methods: To address these gaps, this study included three comprehensive searches to identify the following: (1) the measurement tools used to measure ACEs; (2) the type of ACEs significantly linked with ADV; and (3) the risk and protective factors considered in this relation. Results: A total of 34 studies were included. There were 24 different assessment tools used to measure the ACEs of adolescents, with the number of ACEs included ranging from 1 to 93. All but one study linked at least one ACE to ADV. The types of ACEs linked with ADV consisted of victimization (e.g., child abuse and bullying), witnessing violence (i.e., home and school), and household dysfunction (e.g., caregiver substance abuse). Several risk and protective factors were considered. Conclusions/Implications: This study found the measurement of ACEs in the literature to be inconsistent, making it difficult to synthesize and compare the findings across studies. Despite the measurement inconsistencies, however, most studies linked ACEs with ADV, emphasizing the importance of considering this relation in prevention/intervention programming.

Adverse Childhood Experiences in Parental History and how they Relate to Subsequent Observed Parent–Child Interaction: A Systematic Review

Abstract Background Adverse childhood experiences (ACEs) in parental history have been associated with higher self-reported rates of negative parenting behaviors and lower self-reported rates of positive parenting behaviors. Further research is needed to explore the association between parental ACEs and the observed parent–child interaction quality. Parent–child interactions are a potential pathway behind the continuity of ACEs across generations. Objective This review aimed to expand on existing literature by synthesizing evidence on the associations between parental ACEs and parent–child interactions, assessed through videotaped observations, the gold standard for interaction assessment. Methods A systematic literature search conducted in October 2022 in Medline, EMBASE, and PsycInfo identified twenty-four articles. The studies assessed parental childhood adversity and the quality of parent–child interaction across high- and low-risk samples. Results In 79% of studies, higher rates of childhood adversity were related to lower quality of observed parent–child interaction. Childhood abuse and neglect were linked to fewer positive and more negative parenting behaviors. Among household challenges, only witnessing family violence negatively impacted interaction quality. In 58% of studies, ACEs directly influenced interaction, while in 21% this effect was mediated by other factors. This pattern held across different sample types. Conclusions The evidence suggesting a relationship between parental ACEs and lower quality of parent–child interaction is robust, given the reliability and validity of observational measures. Considering the influence of the quality of parent–child interaction on a child’s development, interventions and prevention programs focusing on parent–child interaction should consider screening for parental ACEs.
