Parents' adverse childhood experiences and mental health screening using home visiting programs: A pilot study

Adverse childhood experiences and intimate partner violence: A meta-analysis

Intimate partner violence (IPV) represents a significant public health concern. Adverse childhood experiences (ACEs) represent one risk factor for IPV, however, the results of existing research on the association between ACEs and IPV demonstrate mixed findings. The present research sought to meta-analytically examine the association between ACEs and (a) IPV perpetration and (b) IPV victimization. Moderator analyses were conducted to determine factors that may impact the association between ACEs and IPV involvement. Electronic searches were conducted in MEDLINE, Embase, and PsycINFO in August of 2021. One-hundred and twenty-three records were screened for inclusion. All studies included a measure of ACEs and IPV victimization or perpetration. Among the 27 studies and 41 samples included in the meta-analysis, 65,330 participants were included. The results of the meta-analyses demonstrated that ACEs were positively associated with IPV perpetration and victimization. Significant methodological and measurement moderators further inform our understanding of ACEs and IPV involvement. The present meta-analyses demonstrates that trauma-informed approaches to IPV screening, prevention, and intervention may be useful, given that individuals who are involved with IPV may be more likely to possess a history of ACEs exposure.

Trauma-informed care education for midwives: Does education improve attitudes towards trauma-informed care?

INTRODUCTION

Continuing education is important to improve midwives' attitudes to trauma-informed care in addressing the needs of women during the perinatal period. This study aimed to evaluate if there was a significant difference in attitudes towards trauma-informed care between midwives who participated in a 2-day trauma-informed care education program and those who did not.

METHOD

A static group comparison design was adopted with a convenience sample of midwives to analyse differences in attitudes towards trauma-informed care between midwives who received a 2-day TIC education (n = 19, intervention group) and their peers who did not receive the education (n = 18, comparison group).

RESULTS

The results suggest that midwives who participated in a 2-day trauma-informed care education program had significantly higher scores for positive attitudes towards trauma-informed care compared to those who did not take part in the program and that this effect was sustained at 6 months.

CONCLUSION

To minimise perinatal trauma for mothers and babies, midwives require specific trauma-informed care education. This study proposes that trauma-informed care education is a foundational pathway for implementing a trauma-informed care framework across a maternity service.

Maternal Childhood Adversity and Infant Epigenetic Aging: Moderation by Restless Sleep During Pregnancy

Maternal exposure to childhood adversity is associated with detrimental health outcomes throughout the lifespan and may have implications for offspring. Evidence links maternal adverse childhood experiences (ACEs) to detrimental birth outcomes, yet the impact on the infant's epigenome is unclear. Moreover, maternal sleep habits during pregnancy may influence this association. Here, we explore whether restless sleep during pregnancy moderates the association between exposure to maternal childhood adversity and infant epigenetic age acceleration in 332 mother-infant dyads (56% female; 39% Black; 25% Hispanic). During the 2nd trimester, mothers self-reported childhood adversity and past-week restless sleep; DNA methylation from umbilical vein endothelial cells was used to estimate five epigenetic clocks. Multivariable linear regression was used to test study hypotheses. Despite no evidence of main effects, there was evidence of an interaction between maternal ACEs and restless sleep in predicting infant epigenetic age acceleration using the EPIC Gestational Age clock. Only infants whose mothers reported exposure to both ACEs and restless sleep demonstrated accelerated epigenetic aging. Results provide preliminary evidence that maternal childhood adversity and sleep may influence the infant epigenome.

The Influence of Adverse Childhood Experiences on Malevolent Creativity in Young Adulthood

BACKGROUND

Childhood trauma may increase the risk of antisocial behavior in young adulthood. Our study examined the relationship between Adverse Childhood Experiences (ACEs) and the specific antisocial behavior of malevolent creativity (MC), the application of original ideas to purposely harm others, often to gain an unfair advantage through manipulation, threat, or harm.

METHODS

We surveyed college students (N = 524; 78% women) on demographics, ACEs, empathy, social support, coping, general creativity, and malevolent creativity. The data were analyzed via sequential linear regression models.

RESULTS

Reporting ≥ 4 ACEs was associated with increased MC, which remained significant when general creativity and demographics were controlled. The association between higher ACEs and MC was no longer significant when psychosocial control variables (social support, empathy, and coping) were included in the statistical model. Social support and empathy were negatively associated with MC, while coping and MC were positively associated.

CONCLUSIONS

ACEs may increase the likelihood of malevolent creativity in young adulthood, but empathy and social support may disrupt this trajectory. Care should be taken that coping skills, while typically viewed as a positive addition to one's behavioral repertoire, do not push individuals toward over-reliance on themselves, which may reduce prosocial behaviors and increase MC.

The Feasibility of the Adverse Childhood Experiences Questionnaire among Women in Danish Antenatal Care: A Mixed-Methods Study

A traumatic upbringing increases the risks of antenatal health problems, unfavourable pregnancy outcomes, and mental disorders. Such childhood experiences may affect women's pa-renting skills and the social-emotional functioning of their children. Research on screening for adverse childhood experiences in antenatal care is limited. The objective of this study was to explore pregnant women's attitudes towards and experiences of an adverse childhood experiences questionnaire, and to assess the relevance of the questionnaire among a population of pregnant women referred to antenatal care levels one and two, targeting women who are generally not perceived to be vulnerable. Data were collected at three maternity wards and consisted of quantitative data on 1352 women's adverse childhood experience scores, structured observations of 18 midwifery visits, and in-depth interviews with 15 pregnant women. Quantitative data were analysed by descriptive statistics, and qualitative data were analysed using systematic text condensation. The qualitative analysis revealed two main categories: "Being screened for childhood adversities" and "Having adverse childhood experiences". In the study population, the prevalence of adverse childhood experiences was high. The women assessed the adverse childhood experiences questionnaire to be a relevant and acceptable screening method. Furthermore, women's perceptions of their relationship with their midwife greatly impacted their attitudes towards and experiences of the questionnaire.

Does screening or routine enquiry for adverse childhood experiences (ACEs) meet criteria for a screening programme? A rapid evidence summary

BACKGROUND

Adverse childhood experiences (ACEs) are traumatic events in childhood that can have impacts throughout life. It has been suggested that ACEs should be 'screened' for, or routinely enquired about, in childhood or adulthood. The aim of this work is to review evidence for this against the United Kingdom National Screening Committee (UKNSC) programme criteria.

METHODS

A rapid review of evidence on ACEs screening was conducted using the approach of the UKNSC.

RESULTS

Good quality evidence was identified from meta-analyses for associations between ACEs and a wide range of adverse outcomes. There was no consistent evidence on the most suitable screening tool, setting of administration, and time or frequency of use. Routine enquiry among adults was feasible and acceptable to service users and professionals in various settings. A wide range of potentially effective interventions was identified. Limited evidence was available on the potential for screening or routine enquiry to reduce morbidity and mortality or possible harms of screening.

CONCLUSIONS

Based on the application of available evidence to UKNSC screening criteria, there is currently insufficient evidence to recommend the implementation of a screening programme for ACEs. Further research is needed to determine whether routine enquiry can improve morbidity, mortality, health and wellbeing.

Identification of families in need of support: Correlates of adverse childhood experiences in the right@home sustained nurse home visiting program

Background

Little is known about the efficacy of pregnancy screening tools using non-sensitive sociodemographic questions to identify the possible presence of as yet undiagnosed disease in individuals and later adverse childhood events disclosure.

Objectives

The study aims were to: 1) record the prevalence of risk disclosed by families during receipt of a sustained nurse home visiting program; and 2) explore patterns of relationships between the disclosed risks for their child having adverse experiences and the antenatal screening tool, which used non-sensitive demographic questions.

Design

Retrospective, observational study.

Participants and methods

Data about the participants in the intervention arm of the Australian right@home trial, which is scaffolded on the Maternal Early Childhood Sustained Home-visiting model, collected between 2013 and 2017 were used. Screening data from the 10-item antenatal survey of non-sensitive demographic risk factors and disclosed risks recorded by the nurse in audited case files during the subsequent 2 year intervention were examined (n = 348). Prevalence of disclosed risks for their child having adverse experiences were analysed in 2019 using multiple response frequencies. Phi correlations were conducted to test associations between screening factors and disclosed risks.

Results

Among the 348 intervention participants whose files were audited, 300 were noted by nurses to have disclosed risks during the intervention, with an average of four disclosures. The most prevalent maternal disclosures were depression or anxiety (57.8%). Mental health issues were the most prevalent partner and family disclosures. Screening tool questions on maternal smoking in pregnancy, not living with another adult, poverty and self-reporting anxious mood were significantly associated with a number of disclosed risks for their child having adverse experiences.

Conclusions

These findings suggest that a non-sensitive sociodemographic screening tool may help to identify families at higher risk for adverse childhood experiences for whom support from a sustained nurse home visiting program may be beneficial.

Trauma-Informed Home Visiting Models in Public Health Nursing: An Evidence-Based Approach

Traumatic experiences can have significant health effects, particularly when they are experienced during childhood. Structural determinants of health including environmental disasters and limited access to mental health services and affordable housing can contribute additional stress for parents with a personal history of childhood adversity. These factors can directly affect their children, contributing to intergenerational trauma. Pregnant people and families with young children are often referred to public health nursing maternal and child home visiting (HV) programs when there are concerns about historical or evolving childhood trauma. The strict eligibility and participation requirements of existing evidence-based maternal and child HV programs can exclude families that have experienced or are experiencing childhood trauma and its effects and can limit innovation by public health nurses, a hallmark of the field. Therefore, we advocate and describe the implementation of the Trauma Informed Approach in Public Health Nursing (TIA PHN) model, which incorporates a trauma-informed approach into a traditional maternal and child HV program in 3 California counties. TIA PHN, which began enrollment in March 2021, involves public health nurses and community health workers and integrates program evaluations in pursuit of evidence-based status.

The Impact of Maternal Adverse Childhood Experiences on Offspring's Internalizing and Externalizing Problems

OBJECTIVE

Adverse childhood experiences (ACEs) are associated with negative physical and mental health outcomes across the lifespan, but research on intergenerational transmission of maternal ACEs and its impact on the offspring's mental health problems are limited. The study examines the effects of maternal ACEs on the risk of internalizing or externalizing problems among offspring.

METHODS

There were 450 mother-child dyads. Mothers completed the Adverse Childhood Experiences Questionnaire. The child outcomes included internalizing and externalizing problems assessed by the Korean Child Behavior Checklist (K-CBCL) and Korean Youth Self-Report (K-YSR), depression assessed by the Center for Epidemiological Studies Depression Scale for Children (CES-DC) and anxiety assessed by the Screen for Child Anxiety Related Emotional Disorders (SCARED).

RESULTS

36.1% of mothers experienced at least one ACE, and 11.1% experienced three or more ACEs. Cumulative maternal ACEs were associated with internalizing problems, externalizing problems, depression and anxiety in the offspring. Household dysfunction from maternal ACEs was significantly associated with delinquent behavior, anxiety/depression, and somatic complaints in the offspring.

CONCLUSION

The findings support the hypothesis that maternal ACEs are related to mental health problems in the offspring. Further research is needed to determine the factors mediating intergenerational transmission as well as intervention strategies to prevent ACEs and mental health problems in the offspring.

Trauma informed care education for midwives: An integrative review

BACKGROUND

Nearly half of new mothers describe their childbirth as traumatic. Perinatal trauma impacts both short and long-term biopsychosocial outcomes for mother and child. Midwife trauma-informed care education and practice is essential to mitigate this risk.

OBJECTIVE

This review aimed to identify and describe the nature and extent of trauma informed care education provided for midwives and midwifery students.

DESIGN

An integrative review.

METHODS

Five databases (Medline, Embase, CINAHL, Psycinfo, and Emcare) were searched to identify primary research regarding trauma informed care education for midwives and midwifery students. Quality appraisal was conducted using the Mixed Methods Appraisal Tool.

RESULTS

Three papers were identified. None of the papers were midwifery focused, with midwives representing a small proportion of the participants. Most midwives reported receiving no previous trauma informed care education and lacked confidence to provide quality care to women with lived trauma. Midwives reported trauma informed care education as essential and relevant for providing quality practice. Improvements in knowledge, skills and attitudes was demonstrated following trauma informed care education. More in-depth content and content delivered in multiple ways were recommended.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Midwives are well placed to deliver trauma informed care. Trauma informed care education for midwives is limited. Given the impact of perinatal trauma, further trauma informed care education and research is paramount.

Screening for adverse childhood experiences in preventive medicine settings: a scoping review

Aim

Adverse childhood experiences (ACEs) are associated with numerous adverse mental and physical health outcomes. While interest in routine screening for ACEs is growing, there is still significant opposition to universal screening. This review explores the feasibility of implementing routine screening for ACEs in primary care settings.

Subject and methods

We searched PubMed, CINAHL, and PsycINFO, reference-mined relevant reviews, and consulted with key experts (June 2020). Studies from 1970 to date evaluating screening for childhood trauma, adversity, and ACEs in a routine healthcare setting, reporting quantitative or qualitative data were eligible. The project is registered in Open Science Framework (osf.io/5wef8) and reporting follows PRISMA-ScR guidelines.

Results

Searches retrieved 1402 citations. Of 246 publications screened as full text, 43 studies met inclusion criteria. Studies evaluated provider burden, familiarity with ACEs, practice characteristics, barriers to screening, frequency of ACE inquiry, reported or desired training, patient comfort, and referrals to support services.

Conclusions

This review found that the following factors increase the likelihood that ACE screenings can be successfully integrated into healthcare settings: staff trainings that increase provider confidence and competence in administering screenings, accessible and robust mental health resources, and organizational support. Further research should examine the scalability and sustainability of universal screening.

Disentangling adversity timing and type: Contrasting theories in the context of maternal prenatal physical and mental health using latent formative models

Research on the effects of adversity has led to mounting interest in examining the differential impact of adversity as a function of its timing and type. The current study examines whether the effects of different types (i.e., physical, sexual, and emotional abuse) and timing (i.e., early, middle childhood, adolescence, or adulthood) of adversity on maternal mental and physical health outcomes in pregnancy, are best accounted for by a cumulative model or independent effects model. Women from a prospective pregnancy cohort (N =3,362) reported retrospectively on their experiences of adversity (i.e., physical, sexual, and emotional abuse) in early childhood (0-5 years], middle childhood (6-12 years], adolescence (13-18 years], and adulthood (19+ years]. Measures of overall health, stress, anxiety, and depression were gathered in pregnancy. Results showed that a cumulative formative latent model was selected as more parsimonious than a direct effects model. Results also supported a model where the strength of the effect of adversity did not vary across abuse timing or type. Thus, cumulative adversity resulted in greater physical and mental health difficulties. In conclusion, cumulative adversity is a more parsimonious predictor of maternal physical and mental health outcomes than adversity at any one specific adversity timing or subtype.

Exploring maternal adversity and childhood outcomes among low-income rural families

BACKGROUND

Research has linked adversity among mothers to poorer outcomes among their offspring. However, additional inquiry is warranted particularly in rural communities where risk factors for adversity are prevalent.

OBJECTIVE

This study had two objectives: (1) to describe and compare relationships between individual and cumulative maternal adversity with childhood outcomes; and, (2) to determine if mother-child attachment mediated the relationship between maternal adversity and childhood outcomes.

PARTICIPANTS AND SETTING

A convenient sample of 140 women with low socio-economic status (SES) were recruited through Head Start programs in the rural Midwest.

METHODS

Data was gathered using a survey comprised of multiple measures to assess maternal adversity and childhood outcomes (i.e. behavior and attachment). Data were analyzed in SPSS using bivariate and multivariate analyses, including stepwise regression.

RESULTS

Nearly 80 % of respondents experienced at least one adverse childhood experience (ACE) and 48 % reported having one or more traumatic experiences. Higher levels of adversity were associated with increased attention problems, increased emotional reactivity, and decreased harmonious attachment (p < .05, d = 0.37-0.38). Maternal experiences of childhood physical abuse and sexual abuse, as well as witnessing trauma, significantly predicted childhood outcomes, however, the variance accounted for by each type of adversity was small (4%-6%). Maternal adversity was unrelated to mother-child attachment.

CONCLUSIONS

Low-SES mothers in rural communities have significant histories of adversity. It is important to consider individual and cumulative adverse experiences, as well as the mother's perception of events as traumatic. Factors associated with rural communities and Head Start programming, as well as implications for research and practice surrounding maternal adversity and childhood outcomes, are discussed.

Combinations of adverse childhood events and risk of postpartum depression among mothers enrolled in a home visiting program

PURPOSE

The purpose of this study was to examine how combinations of adverse childhood events (ACEs) contribute to the risk of postpartum depression and the mediating role of prenatal social support.

METHODS

The Adverse Childhood Experiences Scale Questionnaire and the Edinburgh Postnatal Depression Scale Questionnaire were used to measure the study's exposure and outcome. Among a cohort of 419 mothers enrolled in a home visiting (HV) program, latent class analyses were used to identify classes of ACEs exposure. General linear models assessed the risk of postpartum depression, and prenatal social support was examined as a mediator.

RESULTS

Four distinct classes of ACE exposure were identified. On the Edinburgh Postnatal Depression scale, mothers who were classified in Classes 1-3 scored higher by 2.6-4.4 points compared with women in Class 0. ACE class was found to be indirectly associated with postpartum depression scores through prenatal social support.

CONCLUSIONS

Identifying combinations of ACEs in an HV program has the potential to improve the characterization of ACEs among low-income perinatal women in the United States. Elucidating how these combinations contribute to the risk of postpartum depression has the potential to identify women at increased risk, which can help HV programs prioritize prevention efforts.

Screening for Adverse Childhood Experiences: Literature Review and Practice Implications

Adverse childhood experiences (ACEs) are linked with negatively impacting child and adult health outcomes. Clinicians are integral in identifying childhood adversities and offering supportive measures to minimize negative effects. This systematic literature review included 13 ACE studies that examined the acceptability, feasibility, and implementation of ACE screenings from the perspectives of clinicians and patients. The findings of this review can assist clinicians in considering the appropriateness of ACE screenings for their patients and the ethical and practical issues that must be addressed for effective screening implementation.

The Child Life Challenges Scale (CLCS): Associations of a Single-Item Rating of Global Child Adversity with Children's Total Life Stressors and Parent's Childhood Adversity

BACKGROUND

Although many existing measures tabulate specific risk factors to yield cumulative risk indices, there is a need for low-burden strategies to estimate general adversity exposure.

AIMS AND METHODS

This study introduces a brief, new measure of lifetime adversity, the Child Life Challenges Scale (CLCS), and examines its validity in a sample of parents and children residing in emergency housing. The CLCS comprises a single global item for rating cumulative life challenges utilizing either a paper-pencil scale or a sliding scale on a tablet. Parents are provided with anchor examples of mild and extreme challenges and asked to mark a location along the scale reflecting number and severity of challenges in their children's lives to date. Study participants included 99 parents and their 3- to 6-year-old children.

RESULTS

CLCS scores were moderately associated with children's parent-reported total life stressors, and these associations were robust to controls for parental history of adversity, parental distress, and family demographics. Control variables also did not moderate associations between CLCS scores and total life stressors, suggesting that the CLCS functions similarly across a range of sociodemographic risk. Paper-pencil and tablet versions showed similar convergent validity.

CONCLUSION

The CLCS shows promise as an efficient measure for estimating children's lifetime adversity with minimal parent or administrator burden.

Youth exposure to violence involving a gun: evidence for adverse childhood experience classification

Adverse childhood experiences (ACEs) have historically included child maltreatment, household dysfunction, and other critical issues known to impact children negatively. Although youth experiences with violence are broadly captured in some ACE measures, youth exposure to violence involving a gun has not been included specifically in the operationalizing, and therefore scientific study, of ACEs. There are numerous implications of this omission, including limiting access to ACE interventions that are currently available and resources for individuals who have been exposed to gun violence. Thus, and given the persistent prevalence of gun violence in the US, we conducted a systematic review of the literature over the past two decades on the assessment of and response to ACEs and gun violence. Eighty-one journal articles across four search engines met our inclusion criteria. Our findings provide evidence that youth gun violence exposure should be classified as an ACE. In addition to increasing access to resources for youth affected by gun violence, these findings may improve the likelihood of funding and research into gun violence, with direct implications for prevention and intervention efforts.

The evidence base for routine enquiry into adverse childhood experiences: A scoping review

BACKGROUND

Exposure to adverse childhood experiences (ACEs; e.g., maltreatment, household dysfunction) is associated with a multiplicity of negative outcomes throughout the life course. Consequently, increasing interest is being paid to the application of routine enquiry for ACEs to enable identification and direct interventions to mitigate their harms.

OBJECTIVE

To explore the evidence base for retrospective routine enquiry in adults for ACEs, including feasibility and acceptability amongst practitioners, service user acceptability and outcomes from implementation.

METHODS

A scoping review of the literature was conducted, drawing upon three databases (CINAHL, MEDLINE, PsycINFO) and manual searching and citation tracking. Searches included studies published from 1997 until end of April 2018 examining enquiry into ACEs, or the feasibility/acceptability of such enquiry across any setting. All included studies presented empirical findings, with studies focusing on screening for current adversities excluded.

RESULTS

Searches retrieved 380 articles, of which 15 met the eligibility criteria. A narrative approach to synthesize the data was utilized. Four studies examined practitioner feasibility and/or acceptability of enquiry, three reported service user acceptability and six studies implemented routine ACE enquiry (not mutually exclusive categories). Further, eight studies explored current practice and practitioner attitudes towards ACE enquiry.

CONCLUSIONS

Limited literature was found providing evidence for outcomes from enquiry. No studies examined impacts on service user health or service utilization. Few studies explored feasibility or acceptability to inform the application of routine ACE enquiry. The implementation of routine ACE enquiry therefore needs careful consideration. Focus should remain on evaluating developing models of ACE enquiry to advance understanding of its impact.

Integrative Review of Pregnancy Health Risks and Outcomes Associated With Adverse Childhood Experiences

OBJECTIVE

To identify pregnancy risk factors and outcomes associated with a woman's history of adverse childhood experiences (ACEs) and summarize what is known about routine screening for ACEs as part of prenatal care.

DATA SOURCES

The Academic Search Premier, Academic Search Complete, CINAHL, Health Source: Nursing Academic Edition, MEDLINE, PsychINFO, and PubMed databases were searched. The terms adverse childhood experiences or ACEs, trauma informed care, and childhood trauma were each paired individually with the terms pregnancy or pregnant or prenatal or antenatal or perinatal or maternal; obstetrics; and maternal-child health.

STUDY SELECTION

Database and reference list searches resulted in 1,626 articles with 230 retained for full review and 17 included in the final sample. Studies were included if results were reported specific to pregnancy and ACEs as operationally defined in the ACE Study.

DATA EXTRACTION

Studies were evaluated for methodologic quality using Joanna Briggs Institute appraisal tools. Data were extracted with the matrix method. Tabular synthesis was used to cluster and compare findings and identify themes.

DATA SYNTHESIS

Five categories of pregnancy health risks and outcomes related to ACEs were identified: physiologic risk, psychologic risk, social risk, behavioral risk, and negative pregnancy outcomes. Limited research was found on routine screening for ACEs as part of prenatal care, but findings indicated women's support for ACE screening during prenatal appointments.

CONCLUSION

Routine prenatal ACE screening may be accepted by women and may help identify significant pregnancy health risks. This could provide opportunities for interventions that improve pregnancy outcomes. More research is needed to determine the most effective and efficient methods to screen pregnant women for ACEs and intervene for those with high screening scores. To optimally advance science in this area, conceptual and operational clarity in ACE research is important. Nurses should be at the forefront of these research and practice translation efforts.

How adverse childhood experiences relate to single and multiple health risk behaviours in German public university students: a cross-sectional analysis

Background

Adverse childhood experiences (ACEs) have been shown to be linked to health risk behaviours (HRBs). This study aims to identify risk factors for ACEs and to examine the associations between ACEs and single and multiple HRBs in a sample of university students in Germany.

Methods

An online-based cross-sectional study was conducted among public university students (N = 1466). The widely applied ACE questionnaire was used and extended to operationalise 13 categories of childhood adversity. First, variables for each type of ACE and HRB were dichotomised (single ACEs and single HRBs), and then used for cumulative scores (multiple ACEs and multiple HRBs). Frequencies were assessed, and (multinomial) logistic regression analyses were performed.

Results

Prevalence rates of ACEs ranged from 3.9 to 34.0%, depending on the type of childhood adversity. Sociodemographic risk and protective factors for single/multiple ACEs varied strongly depending on the outcome. In particular, a high family socioeconomic status seemed to be a consistent protective factor for most ACEs. After adjusting for sociodemographic characteristics, both single and multiple HRBs were associated with single events of ACEs. Moreover, dose-response relationships between multiple ACEs and various single and multiple HRBs were found.

Conclusions

The study provides strong evidence that ACEs are associated with HRBs. The number of ACEs may play a role in single or multiple HRBs. Reducing the number of ACEs could thus decrease HRBs, which account for many of the leading causes of morbidity and death. The findings highlight the importance of trauma-informed health interventions designed to prevent the occurrence of ACEs, and build capacity among children and adults.
