Adverse Childhood Experiences and Health Conditions and Risk Behaviors Among High School Students - Youth Risk Behavior Survey, United States, 2023.

Adverse childhood experiences (ACEs) are preventable, potentially traumatic events occurring before age 18 years. Data on ACEs among adolescents in the United States have primarily been collected through parent report and have not included important violence-related ACEs, including physical, sexual, and emotional abuse. This report presents the first national prevalence of self-reported ACEs among U.S. high school students aged <18 years, estimates associations between ACEs and 16 health conditions and risk behaviors, and calculates population-attributable fractions of ACEs with these conditions and behaviors using cross-sectional, nationally representative 2023 Youth Risk Behavior Survey data. Exposures were lifetime prevalence of individual (emotional, physical, and sexual abuse; physical neglect; witnessed intimate partner violence; household substance use; household poor mental health; and incarcerated or detained parent or guardian) ACEs and cumulative ACEs count (zero, one, two or three, or four or more). Health conditions and risk behaviors included violence risk factors, substance use, sexual behaviors, weight and weight perceptions, mental health, and suicidal thoughts and behaviors. Bivariate analyses assessed associations between individual and cumulative ACEs and demographics. Adjusted prevalence ratios assessed associations between cumulative ACEs and health conditions and risk behaviors, accounting for demographics. Population-attributable fractions were calculated to determine the potential reduction in health conditions and risk behaviors associated with preventing ACEs. ACEs were common, with approximately three in four students (76.1%) experiencing one or more ACEs and approximately one in five students (18.5%) experiencing four or more ACEs. The most common ACEs were emotional abuse (61.5%), physical abuse (31.8%), and household poor mental health (28.4%). Students who identified as female; American Indian or Alaska Native; multiracial; or gay or lesbian, bisexual, questioning, or who describe their sexual identity in some other way experienced the highest number of ACEs. Population-attributable fractions associated with experiencing ACEs were highest for suicide attempts (89.4%), seriously considering attempting suicide (85.4%), and prescription opioid misuse (84.3%). ACEs are prevalent among students and contribute substantially to numerous health conditions and risk behaviors in adolescence. Policymakers and public health professionals can use these findings to understand the potential public health impact of ACEs prevention to reduce adolescent suicidal behaviors, substance use, sexual risk behaviors, and other negative health conditions and risk behaviors and to understand current effects of ACEs among U.S. high school students.

The Impact of Adverse Childhood Experiences on Depression and Suicidality in Patients with Schizophrenia.

BACKGROUND: This study aims to investigate the association of adverse childhood experiences (ACE) and depressive symptoms on suicidality in patients with schizophrenia (SCZ) in the Outpatient Consultative Department of the Riga Centre of Psychiatry and Narcology (RPNC). SUBJECTS AND METHODS: A descriptive cross-sectional study was conducted in adult outpatients with SCZ who had not been hospitalized for at least three months. Suicidality was assessed using the Risk Assessment Suicidality Scale (RASS). Depressive symptoms were evaluated with the Calgary Depression Scale for Schizophrenia (CDSS), and ACE were investigated using the Childhood Trauma Questionnaire - Short Form (CTQ-SF). Statistical methods used: Chi-squared test, Fisher's exact test. RESULTS: In total 60 outpatients diagnosed with SCZ were interviewed. It was found that the association between ACE and the frequency of suicide attempts in the study participants during lifetime was statistically significant (χ2=7.255, p=0.027). Self-harm attempts during whole life also differed between participants with and without childhood abuse history (χ2=9.902, p=0.002). Suicidal ideation was observed statistically significantly more often in patients with ACE in comparison with those without ACE (χ2=24.935, p<0.001). Patients with positive childhood abuse history were also observed to be depressed more often (χ2=4.659, p=0.031) in comparison with patients without ACE. Suicidal ideation was found to be more frequent among respondents who were observed to be depressed (CDSS score > 6) during the interview (χ2=14.614, p<0.001). CONCLUSIONS: This study contributes to the existing body of knowledge on suicide attempts, suicidal ideation, and the prevalence of depression in patients with schizophrenia (SCZ) who have a history of childhood abuse. Findings indicate that suicidal ideation is more prevalent among patients experiencing depression at the time of the interview. Personalized interventions are recommended for patients with SCZ who have adverse childhood experiences (ACE) due to their increased risk of suicide attempts.

The association between patterns of exposure to adverse life events and the risk of chronic kidney disease: a prospective cohort study of 140,997 individuals.

Exposure to adverse life events is linked to somatic disorders. The study aims to evaluate the association between adverse events at varying life stages and the risk of chronic kidney disease (CKD), a condition affecting about 10% population worldwide. This prospective cohort study included 140,997 participants from the UK Biobank. Using survey items related to childhood maltreatment, adulthood adversity and catastrophic trauma, we performed latent class analysis to summarize five distinct patterns of exposure to adverse life events, namely "low-level exposure", "childhood exposure", "adulthood exposure", "sexual abuse" and "child-to-adulthood exposure". We used Cox proportional hazard regression to evaluate the association of patterns of exposure to adverse life events with CKD, regression-based mediation analysis to decompose the total effect, and gene-environment-wide interaction study (GEWIS) to identify interactions between genetic loci and adverse life events. During a median follow-up of 5.98 years, 2734 cases of incident CKD were identified. Compared with the "low-level exposure" pattern, "child-to-adulthood exposure" was associated with increased risk of CKD (hazard ratio 1.37, 95% CI 1.14 to 1.65). BMI, smoking and hypertension mediated 11.45%, 9.79%, and 4.50% of this total effect, respectively. Other patterns did not show significant results. GEWIS and subsequent analyses indicated that the magnitude of the association between adverse life events and CKD differed according to genetic polymorphisms, and identified potential underlying pathways (e.g., interleukin 1 receptor activity). These findings underscore the importance of incorporating an individual's psychological encounters and genetic profiles into the precision prevention of CKD.

The relationship between childhood trauma and mental health status among Chinese vocational high school adolescents: the mediating effect of poor self-control and internet addiction.

BACKGROUND: Mental health problems among adolescents are a common concern globally. However, its relationship with childhood trauma is not clearly understood from the existing studies. Therefore, this study aims to explore the relationships among childhood trauma, mental health, self-control, and internet addiction in Chinese vocational high school students. METHODS: A cross-sectional survey was conducted among vocational high school students in China from October 2020 to December 2020. Standardized questionnaires were used to collect basic information regarding childhood trauma, self-control, psychological state, and social demographics. A structural equation model was used to study the relationships among internet addiction, self-control, childhood trauma, and mental health. RESULTS: A total of 3368 individuals participated in the study. The results revealed the mediating effects of poor self-control and internet addiction on the association between childhood trauma and mental health. CONCLUSIONS: Internet addiction and low self-control play mediating roles in childhood trauma and mental health. Clarifying these relationships will help formulate better-targeted interventions to improve the mental health of Chinese vocational high school students and aid in interventions to treat and prevent mental health problems.

Receipt of social services intervention in childhood, educational attainment and emergency hospital admissions: longitudinal analyses of national administrative health, social care, and education data in Wales, UK.

BACKGROUND: Research consistently finds poorer health and educational outcomes for children who have experienced out-of-home care relative to the general population. Few studies have explored differences between those in care and those in receipt of intervention from social services but not in care. Children receiving social services interventions often experience Adverse Childhood Experiences (ACEs), and deprivation, which are known to negatively impact outcomes. We aimed to estimate the association of different social services interventions with educational outcomes and hospital admissions, while adjusting for ACEs and deprivation. METHODS: We linked retrospective, routinely collected administrative records from health, education, and social care to create a cohort via the Secure Anonymised Information Linkage (SAIL) databank in Wales, UK. We analysed data for children and household members (N = 30,439) across four different groups: [1] no social care intervention; [2] children in need but not in care (CIN); [3] children on the Child Protection Register but not in care (CPR); [4] children in care - i.e. removed from the family home and looked after by the local authority (CLA). Our primary outcome was education outcomes at age 16 years. Secondary outcomes were all cause emergency hospital admissions, and emergency admissions for external causes/injuries. RESULTS: Children in receipt of social services intervention were more likely to not attain the expected level upon leaving statutory education at age 16 after adjusting for ACEs and other characteristics (for children who had been in out-of-home care (conditional OR: 1·76, (95%CI) 1·25 - 2·48), in need (2·51, 2·00-3·15) and those at risk (i.e., on the child protection register) (4·04, 2·44 - 6·68). For all-cause emergency admissions, all social care groups were at greater risk compared to children in the general population (children in care (conditional HR: 1·31, 1·01-1·68), children in need (1·62, 1·38 - 1·90), and children at risk (1·51, 1·11 - 2·04). CONCLUSIONS: All groups receiving social service intervention experience poorer educational and health outcomes than peers in the general population. Children who remain with their home parents or caregivers but are identified as 'in need' or 'at risk' by social care practitioners require further research. Integrated support is needed from multiple sectors, including health, educational and social care.

Effects of adverse childhood experiences on university students' ability to lead healthy lives: an exploratory qualitative study in Lahore, Pakistan.

BACKGROUND: Adverse Childhood Experiences are a significant global public health concern as these experiences have adverse effects on all the health determinants. METHODS: The interpretive phenomenological research design was used to explore the implications of adverse childhood experiences on the adult life of university students. An interpretive thematic analysis method was employed to analyze this study. RESULTS: Five major themes emerged after a comprehensive review of the information obtained from the interviews with the ten selected participants. These were (1) Chronic health struggles (2) Mental health disorders (3) Emotional and social difficulties (4) Paranoia and distrust and (5) Academic and professional under-performance. CONCLUSION: This study concludes that adverse childhood experiences have long-lasting negative effects on university students' health and behaviour, preventing them from leading healthy lives and excelling academically and professionally.

Relevance of ACE Scores in Teens with Depression and Anxiety: A Maui Pilot Study.

In the aftermath of the Covid pandemic and the notable rise of teen depression and anxiety (DA), there is an urgent need to focus on youth mental health. Another important variable to consider is the presence of adverse childhood experiences (ACE), which can be associated with chronic mental and physical health conditions. This pilot study explores how ACEs relate to DA for adolescents in Maui, Hawai'i. The cohort was 75 patients seen at a Kaiser Pediatric Clinic in the spring of 2022. Data was collected from standard questionnaires and the Pediatric ACEs and Life-Events Screener (PEARLS). There were significant associations between DA and a high ACE score (4+), as well as female sex. A high ACE score can alert providers to initiate a trauma informed dialogue with patients. The effects of trauma are not often discussed at routine visits. Mental health care needs and community support can also be addressed as needed. The PEARLS questionnaire is a standard tool to help clinicians be more trauma-informed. This study explores its relevance at routine adolescent visits.

Differential effects of lifetime stressors on major depressive disorder severity: a longitudinal community-based cohort study.

BACKGROUND: Stressors across the lifespan are associated with the onset of major depressive disorder (MDD) and increased severity of depressive symptoms. However, it is unclear how lifetime stressors are related to specific MDD subtypes. The present study aims to examine the relationships between MDD subtypes and stressors experienced across the lifespan while considering potential confounders. METHODS: Data analyzed were from the Zone d'Épidémiologie Psychiatrique du Sud-Ouest de Montréal (N = 1351). Lifetime stressors included childhood maltreatment, child-parent bonding, and stressful life events. Person-centered analyses were used to identify the clusters/profiles of the studied variables and multinomial logistic regression analyses were performed to examine the relationships between stressors and identified MDD subtypes. Intersectional analysis was applied to further examine how distal stressors interact with proximal stressors to impact the development of MDD subtypes. RESULTS: There was a significant association between proximal stressors and melancholic depression, whereas severe atypical depression and moderate depression were only associated with some domains of stressful life events. Additionally, those with severe atypical depression and melancholic depression were more likely to be exposed to distal stressors such as childhood maltreatment. The combinations of distal and proximal stressors predicted a greater risk of all MDD subtypes except for moderate atypical depression. CONCLUSIONS: MDD was characterized into four subtypes based on depressive symptoms and severity. Different stressor profiles were linked with various MDD subtypes. More specific interventions and clinical management are called to provide precision treatment for MDD patients with unique stressor profiles and MDD subtypes.

Early-life adversity predicting the incidence of multisite chronic pain in the general population.

INTRODUCTION: Adverse childhood events (ACEs) have been linked to widespread chronic pain (CP) in various cross-sectional studies, mainly in clinical populations. However, the independent role of different ACEs on the development of different types of CP remains elusive. Accordingly, we aimed to prospectively assess the associations between specific types of ACEs with the development of multisite CP in a large population-based cohort. METHODS: Data stemmed from the three first follow-up evaluations of CoLaus|PsyCoLaus, a prospective population-based cohort study of initially 6734 participants (age range: 35-75 years). The present sample included 1537 participants with 2161 analyzable intervals (49.7% men, mean age 57.3 years). Diagnostic criteria for ACEs were elicited using semi-structured interviews and CP was assessed by self-rating questionnaires. Multinomial logistic regressions with generalized estimating equations method analyzed the relationship between the different ACEs measured in the beginning of the interval and the risk of developing multisite CP during the follow-up. Sensitivity analyses were performed to assess the predictive value of ACEs on multisite CP with neuropathic features. RESULTS: Participants with a history of parental divorce or separation had an increased risk of developing multisite CP at during follow-up in comparison to those without (RR1.98; 95% CI 1.13-3.47). A strong association was highlighted between parental divorce or separation and the risk of subsequent CP with neuropathic characteristics (RR 4.21, 95% CI 1.45-12.18). CONCLUSION: These results highlight the importance of psychotherapeutic management of people experiencing parental separation to prevent CP in the future.

The mediating role of behavioral risk factors in the pathway between childhood disadvantage and adult psychological distress in a Finnish employee cohort.

Childhood disadvantage is associated with increased adult psychological distress, but the role of behavioral risk factors in the pathway remains unclear. We examined whether behavioral risk factors mediate the effects of childhood disadvantage on adult psychological distress. We used the Helsinki Health Study data of employees of the City of Helsinki, Finland, aged 19-39 (mean age 32.0) years at baseline (2017). We included women (n = 2397) and men (n = 586) who responded to both baseline and follow-up (2022) surveys. At baseline, eight types of childhood disadvantage were asked retrospectively, and six adult behavioral risk factors were included. Psychological distress was measured by the DASS-21 at follow-up. We conducted mediation analyses using generalized structural equation modeling. Among women, we found indirect path effects of childhood disadvantage on adult psychological distress through behavioral risk factors (symptoms of depression: ß = 0.68, 95% CI 0.20-1.17; anxiety: ß = 0.54, 95% CI 0.13-0.95; and stress: ß = 0.69, 95% CI 0.20-1.09). Among men, childhood disadvantage contributed only directly to adult depressive (ß = 0.71, 95% CI 0.16-1.26) and stress (ß = 0.61, 95% CI 0.10-1.13) symptoms. Our findings suggest that behavioral risk factors can mediate some of the adverse effects of childhood disadvantage on adult psychological distress among women.

Prevalence, subtypes, and risk factors of adverse childhood experiences among Chinese residents: a multicenter cross-sectional study.

Background: Addressing the long-term physical and mental health impacts of adverse childhood experiences (ACEs) remains a significant public health challenge. Additionally, ACEs can contribute to intergenerational transmission, affecting future generations. While previous studies have primarily focused on children and adolescents, there is limited data on ACE subtypes and influencing factors among the general adult population, particularly in China. This study aims to explore the prevalence, subtypes, and factors influencing ACEs among Chinese adults. Method: A total of 1,932 Chinese residents from southwest China (Sichuan, Yunnan, Guizhou provinces, and Chongqing Municipality) participated in the study, consisting of 867 men (44.9%) and 1,065 women (55.1%). Latent class analysis (LCA) was used to identify ACE clusters, and regression analysis examined associations between ACE clusters and demographic factors, physical illness, and mental health outcomes. Results: The findings revealed that 28.7% of participants had experienced at least one ACE, while 13.2% had experienced three or more ACEs. Three distinct ACE clusters were identified: a low ACE group, a high emotional and physical abuse/family dysfunction group, and a high ACE/sexual abuse group. Regression analysis showed significant associations between childhood adversity and demographic factors (age, education, birthplace), as well as physical and mental health outcomes (anxiety, depression). ANOVA further confirmed significant differences in depression and anxiety scores across the clusters. Conclusion: These findings offer critical insights for developing targeted public health interventions. Policymakers should consider strategies to reduce childhood ACEs and mitigate their long-term consequences, with particular attention to high-risk groups.

Adverse childhood experiences predict anxiety during postpartum and early childhood parenting.

Perinatal anxiety disorders (PAD) affect one in five pregnant/postpartum people and are associated with adverse maternal and child health outcomes. Effective treatment and prevention rely on early identification and management of risk factors. Our study fills a gap in literature about how maternal adverse childhood experiences (ACEs) relate to PAD during and beyond the postpartum period. Using longitudinal data from a population-based sample of mothers in Colorado, USA (N = 1116), we evaluated whether maternal ACEs predicted self-reported anxiety symptoms, measured six times between 3 and 36 months postpartum. A mixed mean model of anxiety was fit with ACEs as the predictor and maternal age, race, ethnicity, education, marital status, and parity as covariates. Controlling for sociodemographic covariates, mothers reporting four or more ACEs had significantly higher levels of anxiety than those reporting less than four ACEs (b = 0.84, 95% CI (0.53, 1.15), p<.001) over the three-year period. Mothers of younger age at time of birth (25-34 years vs. <24 years: b=-0.54, 95% CI (-1.00, -0.08), p=.02) and non-Hispanic ethnicity (b = 0.47, 95% CI (0.09, 0.85), p=.01) were also found to have higher anxiety over this period. Our findings support screening for and addressing maternal ACEs early in obstetric care and well-child visits through trauma-informed, strengths-based approaches that promote maternal, child, and intergenerational well-being.

Feasibility Study of Adverse Childhood Experiences, Treatment-Related Sequelae, and Inflammatory Markers in Breast Cancer Survivors.

OBJECTIVES: To explore the incidence of adverse childhood experiences (ACEs) in breast cancer survivors and potential associations with long-term treatment-related sequelae. SAMPLE & SETTING: English-speaking breast cancer survivors three or more years from diagnosis with complete treatment response (N = 120) were recruited prior to scheduled survivorship clinic visits. METHODS & VARIABLES: Participants in this cross-sectional observational feasibility study rated anxiety, depression, fatigue, sleep disturbance, cognitive issues, resilience, and ACEs (experienced prior to age 18 years). Blood samples were analyzed for inflammatory and epigenetic biomarkers. RESULTS: ACEs assessment was feasible. Higher ACE scores correlated with greater fatigue, anxiety, and depression, and with lower cognitive function (p < 0.05). Resilience was positively associated with cognitive function and negatively associated with fatigue, anxiety, and depression. IMPLICATIONS FOR NURSING: There is evidence for the impact of ACEs on long-term treatment-related sequelae in women with breast cancer. Oncology nurses should consider incorporating ACEs assessment into the workflow for women receiving survivorship care.

Prevalence and Risk Factors of Gang Membership in a Brazilian Birth Cohort.

Importance: There is no longitudinal evidence on risk factors for gang membership in low- and middle-income countries, despite organized crime groups posing major challenges, including high homicide rates in Latin America. Furthermore, adverse childhood experiences (ACEs) have been largely overlooked in gang-related research worldwide. Objectives: To examine the associations of ACEs up to 15 years of age with past-year gang membership at 18 years of age and to compare crime and criminal justice involvement between gang members and non-gang members. Design, Setting, and Participants: This cohort study assessed children from the 1993 Pelotas (Brazil) Birth Cohort-an ongoing population-based, prospective study. Assessments were undertaken perinatally (1993) and when the children were ages 11 (2004), 15 (2008), 18 (2011), and 22 (2015) years. All children born in 1993 were eligible (N = 5265), and 5249 (99.7%) were enrolled at birth. The study sample (N = 3794 [72.1%]) included those with complete data on ACEs. Data analyses were conducted from February to August 2024. Exposures: Twelve ACEs were assessed up to 15 years of age via child self-report and/or maternal report, including physical neglect, physical abuse, emotional abuse, sexual abuse, domestic violence, maternal mental illness, parental divorce, ever being separated from parents, parental death, poverty, discrimination, and neighborhood fear. These experiences were examined using a single adversity approach, cumulative risk, and latent classes. Main Outcomes and Measures: The main outcome was past-year gang membership at 18 years of age, assessed via self-report and analyzed using multivariate imputation. Results: Of 3794 participants, 1964 (51.8%) were female and 1830 (48.2%) were male, and 703 (18.5%) were Black, 2922 (77.0%) were White, and 169 (4.5%) were coded as "other" race or ethnicity (no additional details are available to further disaggregate the other category). On the basis of the imputed data, 1.6% (SE, 0.2 percentage points) of participants reported gang membership at 18 years of age. Physical abuse (odds ratio [OR], 2.76; 95% CI, 1.27-5.98), emotional abuse (OR, 2.76; 95% CI, 1.51-5.02), domestic violence (OR, 3.39; 95% CI, 1.77-6.48), parental divorce (OR, 2.04; 95% CI, 1.17-3.54), and separation from parents (OR, 3.13; 95% CI, 1.54-6.37) were associated with an increased risk of gang membership. A dose-response association was observed, with 4 or more ACEs increasing the risk (OR, 8.86; 95% CI, 2.24-35.08). In latent class analysis, the class with child maltreatment and household challenges was associated with a higher risk of gang membership than the low-adversities class (OR, 7.10; 95% CI, 2.37-21.28). There was no robust evidence that children exposed to household challenges and social risks were at increased risk of gang membership (OR, 2.28; 95% CI, 0.46-11.25). Conclusions and Relevance: In this prospective cohort study, ACEs, particularly child maltreatment and family conflict, were associated with gang involvement when examined individually, cumulatively, and as clusters in a high-crime environment in Brazil. These findings underscore the value of integrating the ACE framework into gang-related research and the potential to reduce gang-related crime by reducing ACEs.

Effects of childhood adversities on alexithymia features vary between sexes. Results of a prospective population study.

Introduction: Adverse childhood experiences (ACEs) associate with various mental disorders, including personality features. Our understanding of how ACEs influence alexithymia features in the general population is limited. In a prospective population setting, we studied whether ACEs associate with alexithymia, and the role of sex and emotional symptoms in this association.Methods: In a Finnish population-based prospective study, 3,142 individuals aged between 30 and 64 years completed eleven ACE questions and the Toronto Alexithymia Scale in 2000 and 2011, and the Hopkins Symptoms Checklist in 2011. The effect of ACEs on alexithymia and its subdomains - difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and externally oriented thinking (EOT) in 2000 and 2011 - was analysed using repeated measures ANOVA.Results: The number of ACEs and their main component, childhood social disadvantage, associated positively with total alexithymia scores and its subdomains DIF and DDF, and negatively with EOT. After controlling for the effect of depression and anxiety, the strength of these associations was reduced, but the effect of social disadvantage on DIF and EOT remained significant in females. Childhood family conflicts associated positively with DIF in males and negatively with EOT in females. Additionally, maternal mental problems associated positively with DIF and DDF in females.Discussion: In the general population, ACEs, particularly social disadvantage, are associated with adult alexithymia features. Alexithymia features, detectable from youth, may predispose individuals to emotional disturbances caused by childhood adversities. The effect of family conflicts and maternal mental problems on alexithymia features varies between sexes.

Childhood social disadvantage, a main component of adverse childhood experiences, is associated with increased difficulties in identifying and describing feelings in both sexes, and with decreased externally oriented thinking in females.Childhood family conflicts are associated with increased difficulties in identifying feelings in males, but decreased difficulties in describing feelings and decreased externally oriented thinking in females.Maternal mental problems during childhood are associated with increased difficulties in identifying and describing feelings in females.

Early vs. Later Experiences of Violence and Polysubstance Use Among Adults Who Inject Drugs.

BACKGROUND: People who inject drugs (PWID) experience high rates of violence, especially in early childhood, increasing their likelihood of engaging in risky substance use behavior in adulthood. Additionally, complex trauma has been reported among PWID due to witnessing and experiencing an overdose, further highlighting the need to examine the role of multiple experiences of trauma on their vulnerability to substance misuse. METHODS: Our study of 350 PWID from rural Kentucky examined differences in polysubstance use between participants who experienced violence earlier (≤15 years old) versus later (≥16 years old) in their childhood. RESULTS: Findings highlighted a direct association between experiences of early childhood violence and polysubstance use in adulthood. Additionally, our sample of PWID who experienced violence early in their childhood reported higher rates of severe substance use disorder and mental health distress. CONCLUSIONS: Tailored approaches that incorporate trauma-informed care may help to address the disproportionate rates of substance use and related adverse effects among PWID.

Variations in the association between adverse childhood experiences (ACEs) and depression by age at first occurrence of ACEs.

BACKGROUND: Adverse childhood experiences (ACEs) are known to be associated with depression. However, the extent to which such association varies by age at the first occurrence of ACEs remains unexplored. The objectives of this study are: (1) To describe the association between ACEs and depression among university students in China, and; (2) to assess the extent to which the mentioned association varied by age at first ACE. METHODS: We conducted a self-administered survey among university students in southern China and analyzed the data using descriptive statistics and multivariate logistic regression. RESULTS: We found significant associations between ACEs and depression prevalence, particularly when comparing students with three or more ACEs vs. students with no ACEs (62% vs. 36%; Adjusted OR = 3.49; 95% CI = 1.99, 6.12). Stratified analyses showed that the association was particularly strong among students who first experienced ACEs at age 0-6 years (66% vs. 36%; Adjusted OR = 4.05; 95% CI = 1.90, 8.59), but was non-significant among those who first experienced ACEs at age 13-18 years (31% vs. 36%; Adjusted OR = 0.99; 95 CI = 0.24, 4.08). CONCLUSION: The strength of the associations between ACEs and depression varied by the age at first ACE. However, the cross-sectional study design, potential information bias, and lack of generalizability should be considered as caveats in the interpretation of the study findings.

Adverse childhood experiences, education, and involvement in terrorist violence: Examining mediation and moderation.

Most perpetrators of terrorist violence have had some level of post-secondary school education, with many enrolled in education at the time of their attacks. Exploring this premise in the context of prevention, this article draws from data gathered on a purposive sample (N = 206) of radicalized individuals from Europe and North America, half of whom became involved in terrorist violence at the end of their radicalization trajectories. Through a lens of educational participation, we propose novel, non-linear frameworks for understanding radicalization outcomes. To do so, two factors are explored that uniquely intersect when an individual enters a school setting: Adverse childhood experiences (ACE) and the human capital provided by education. As hypothesized, exposure to ACE was found to be associated with radicalization trajectories culminating in terrorist violence at the bivariate level (OR = 2.08). Consistent with the developmental-assets framework, it was further hypothesized that this relationship would be mediated by enrollment in education; however, results did not support this hypothesis. Instead, consistent with resiliency-based models, it was found that the relationship between ACE and involvement in terrorist violence was significant for those who abandoned education during radicalization (OR = 2.07). As well as contributing to theoretical models of radicalization to terrorist violence, identifying the furtherance of education as a moderator of risk may signal an important preventative strategy for violent extremism. Keeping enrolled students engaged in their programs, even if only nominally, may also forego the need for educators to engage in potentially controversial practices such as alerting the authorities to students who display signs of radicalization.

The association between poverty and longitudinal patterns of adverse childhood experiences across childhood and adolescence: Findings from a prospective population-based cohort study in the UK.

BACKGROUND: Adverse childhood experiences (ACEs) affect up to half the general population, they are known to co-occur, and are particularly common among those experiencing poverty. Yet, there are limited studies examining specific patterns of ACE co-occurrence considering their developmental timing. OBJECTIVE: To examine the longitudinal co-occurrence patterns of ACEs across childhood and adolescence, and to examine the role of poverty in predicting these. PARTICIPANTS AND SETTING: The sample was 8859 children from the Avon Longitudinal Study of Parents and Children, a longitudinal prospective population-based UK birth cohort. METHODS: Repeated measures of ten ACEs were available, occurring in early childhood (birth-5 years), mid-childhood (6-10 years), and adolescence (11-16 years). Latent class analysis was used to identify groups of children with similar developmental patterns of ACEs. Multinomial regression was used to examine the association between poverty during pregnancy and ACE classes. RESULTS: Sixteen percent of parents experienced poverty. A five-class latent model was selected: "Low ACEs" (72·0 %), "Early and mid-childhood household disharmony" (10·6 %), "Persistent parental mental health problems" (9·7 %), "Early childhood abuse and parental mental health problems" (5·0 %), and "Mid-childhood and adolescence ACEs" (2·6 %). Poverty was associated with a higher likelihood of being in each of the ACE classes compared to the low ACEs reference class. The largest effect size was seen for the "Early and mid-childhood household disharmony" class (OR 4·70, 95 % CI 3·68-6·00). CONCLUSIONS: A multifactorial approach to preventing ACEs is needed - including support for parents facing financial and material hardship, at-risk families, and timely interventions for those experiencing ACEs.

The mediating role of adolescent psychopathology in the association between frequent or severe childhood abuse and labor market inactivity in young adulthood: A causal mediation approach.

BACKGROUND: Labor market inactivity is common among young adults with a history of childhood abuse, which might be attributable to elevated psychopathology in adolescence. OBJECTIVE: We examined and decomposed the effect of adolescent psychopathology in the association between frequent or severe childhood abuse and labor market inactivity in young adulthood. PARTICIPANTS AND SETTING: This study used data from the population and high-risk samples of the Dutch prospective TRacking Adolescents' Individual Lives Survey (N = 2172). METHODS: Childhood abuse included measures of emotional, physical and sexual abuse. We operationalized adolescent psychopathology using the broadband emotional and behavioral problem scales. Labor market inactivity in young adulthood was defined as being neither in education, employment nor training or receiving benefits. We applied causal mediation analysis combined with a four-way decomposition approach to estimate our effects of interest. RESULTS: Individuals who reported frequent or severe childhood abuse were 1.51 (95 % CI: 1.13 to 2.22) times more likely to report labor market inactivity, constituting an excess relative risk (ERR) of 0.51. Most of this excess relative risk is due to mediation by psychopathology at 64.7 % (ERR: 0.33, 95 % CI: 0.16 to 0.50). We found no evidence for a mediated interactive effect (ERR: -0.04, 95 % CI: -0.24 to 0.24). CONCLUSIONS: Adolescent psychopathology largely explains the association between frequent and severe childhood abuse and labor market inactivity in young adulthood. Intervening in the occurrence of adolescent psychopathology following frequent and severe childhood abuse may reduce the risk of subsequent labor market inactivity.
