The association between child maltreatment and health risk behaviours and conditions throughout life in the Australian Child Maltreatment Study

Threat, Emotion Dysregulation, and Parenting in a Clinical Sample of Children with Disruptive Behaviour

Early-life adversity is associated with the development of internalizing and externalizing problems in children. Despite this, there is a need to understand the mechanisms linking these experiences to psychopathology, especially in clinical samples. This cross-sectional study tested emotion dysregulation as a mechanism linking early-life threat to psychopathology in a clinical sample of children with disruptive behavior problems. We also explored parental positive reinforcement as a protective factor in these pathways. A clinical sample of 606 children aged 6-12 years, referred to a mental healthcare hospital, were included. Parent-reported child threat, and parent- and teacher-reported child emotion dysregulation and psychopathology, were collected. Path analysis was used to explore the mediating effect of emotion dysregulation in the relation between threat and psychopathology. The moderating effects of parental positive reinforcement were explored through moderated-mediation analyses. Emotion dysregulation partially mediated the association between threat and both internalizing (β = .18, P = .006) and externalizing (β = .19, P = .002) problems. Positive reinforcement did not buffer the association between threat and emotion dysregulation (β = .09, P = .62) or the association between emotion dysregulation and internalizing (β = - .003, P = .20) or externalizing (β = - .002, P = .35). Poor emotion regulation may be a transdiagnostic mechanism linking early-threat with internalizing and externalizing problems in clinic-referred children with disruptive behaviors. Factors aside from parental positive reinforcement should be explored as protective factors in these pathways, including those directly implicated in the purported mechanisms linking these factors over time.

Associations between child maltreatment and hospital admissions for alcohol and other substance use-related disorders up to 40 years of age: Results from the Childhood Adversity and Lifetime Morbidity study

BACKGROUND AND AIMS

Evidence on the associations between child maltreatment (CM), alcohol use disorders (AUDs) and other substance use disorders (SUDs) comes largely from retrospective studies. These rely on self-reported data, which may be impacted by recall bias. Using prospective CM reports to statutory agencies, we measured associations between CM notifications and inpatient admissions for AUDs and SUDs up to 40 years of age.

DESIGN, SETTING AND PARTICIPANTS

Observational study linking administrative health data from Queensland, Australia to prospective birth cohort data comprising both agency-reported and substantiated notifications of CM.

MEASUREMENTS

Outcomes were inpatient admissions for AUDs and SUDs based on ICD-10-Australian modification (AM)-coded primary diagnoses. Unadjusted and adjusted logistic regression analyses were undertaken.

FINDINGS

Ten per cent (n = 609) of the cohort had a history of agency-reported or substantiated CM notifications before age 15. These individuals had higher adjusted odds of being admitted for AUDs and SUDs. For AUDs, the adjusted odds of inpatient admission were 2.86 [95% confidence interval (CI) = 1.73-4.74] greater where there was any previous agency-reported CM and 3.38 (95% CI = 1.94-5.89) greater where there was any previous substantiated CM. For SUDs, the adjusted odds of inpatient admission were 3.34 (95% CI = 2.42-4.61) greater where there was any previous agency-reported CM and 2.98 (95% CI = 2.04-4.36) greater where there was any previous substantiated CM.

CONCLUSIONS

People with a history of child maltreatment appear to have significantly higher odds of inpatient admissions for alcohol use disorders and other substance use disorders up to 40 years of age compared to people with no history of child maltreatment.

The well-being of young adults: The implications of multi-type child maltreatment and the mediating role of betrayal trauma

BACKGROUND

Research indicates that the nature of the relationship between a victim-survivor and perpetrator of child maltreatment can influence well-being experienced during young adulthood. However, further research is required to substantiate the possible mediating role of betrayal trauma following child maltreatment.

OBJECTIVE

To explore the relationship between child maltreatment and psychological well-being experienced during young adulthood by examining the extent of maltreatment, the importance of the type of perpetrator, and the potential mediating role of betrayal trauma following child maltreatment.

PARTICIPANTS AND SETTING

The self-selected sample comprised 468 young adults (aged 18-25 years; M = 21.74 years, SD = 2.47) from Australia and internationally.

METHOD

Information regarding participants' current well-being, the extent of enduring five types of maltreatment (witnessing family violence, neglect, physical abuse, psychological abuse, and sexual abuse) by their mother, father and other adults during childhood, multi-type maltreatment, and severity of betrayal trauma were obtained via an online survey.

RESULTS

Using multiple regression analysis, it was found that higher levels of multi-type maltreatment were associated with poorer current well-being. Maltreatment by one's mother or father predicted poorer well-being, maltreatment by another adult did not. Hierarchical regressions revealed young adults' sense of betrayal trauma in close relationships partially mediated the relationship between current well-being and child maltreatment by one's mother, father, and another adult.

CONCLUSION

Findings show that the extent of child maltreatment experienced, one's sense of betrayal, and the relationship of the child/adolescent to the perpetrator can influence well-being experienced during young adulthood. These findings highlight the therapeutic benefit of clinicians supporting young adults who have endured child maltreatment to process betrayal trauma, to improve their well-being.

More Than What You Eat: A Review on the Association Between Childhood Maltreatment and Elevated Adult BMI

PURPOSE OF REVIEW

Obesity is an overwhelmingly common medical entity seen in the adult population. A growing body of research demonstrates that there is a significant relationship between child maltreatment and adult obesity.

RECENT FINDINGS

Emerging research demonstrates a potential dose-response relationship between various types of child abuse and adulthood BMI. Recent work also explores the potential role of the hypothalamic-pituitary-adrenal (HPA) axis, and other hormonal mediators such as sex-hormone binding globulin and leptin. There are also studies that suggest factors such as depression and socioeconomic and environmental influences mediate this relationship. Comorbidities that have been reported include cardiovascular and metabolic disease, diabetes, and insulin resistance. Preliminary work also demonstrates potential gender and racial disparities in the effect of abuse on adulthood obesity. In this narrative review, we summarize the existing work describing the different child maltreatment types (physical, sexual, emotional, verbal, and child neglect) and their relation to adult obesity, what is known about a potential dose-response relationship, potential mediators and pathophysiology, comorbidities, and preliminary work on gender and racial/ethnic disparities. We review the limited data on interventions that have been studied, and close with a discussion of implications and suggestions for clinicians who treat adult obesity, as well as potential future research directions.

Emergency department presentations for deliberate self-harm and suicidal ideation in 25-39 years olds following agency-notified child maltreatment: results from the Childhood Adversity and Lifetime Morbidity (CALM) study

AIMS

To compare prospective reports of child maltreatment (CM) with emergency department (ED) presentations for deliberate self-harm (DSH) and suicidal ideation in individuals aged between 25 and 39 years old.

METHODS

Linked records between the Mater-University of Queensland Study of Pregnancy birth cohort and Queensland administrative health data were used, which included notifications to child protection agencies for CM. ED presentations for individuals aged between 25 and 39 years of age for suicidal ideation, suicidal behaviour or poisoning by paracetamol or psychotropic medications where the intention was unclear were examined using logistic regression analyses.

RESULTS

A total of 609 (10.1%) individuals were the subject of one or more CM notifications for neglect or physical, sexual or emotional abuse before the age of 15 years. Of these, 250 (4.1%) presented at least once to ED for DSH and/or suicidal ideation between 25 and 39 years of age. In adjusted analysis, any notification of CM was associated with significantly increased odds of presenting to ED for these reasons (aOR = 2.80; 95% CI = 2.04-3.84). In sensitivity analyses, any notification of CM increased the odds of the combined outcome of DSH and suicidal ideation by 275% (aOR = 2.75; 95% CI = 1.96-4.06) and increased the odds of DSH alone by 269% (aOR = 2.69; 95% CI = 1.65-4.41).

CONCLUSIONS

All CM types (including emotional abuse and neglect) were associated with ED presentations for DSH and suicidal ideation in individuals between 25 and 39 years of age. These findings have important implications for the prevention of DSH, suicidal ideation and other health outcomes. They also underscore the importance of trauma-informed care in ED for all individuals presenting with DSH and suicidal ideation.

[Emotional Maltreatment of Children and Adolescents - Definitions, Prevalences, Risk Factors and Psychological Consequences]

The aim of this article is to provide an introductory overview of the phenomenon of emotional maltreatment of children and adolescents by presenting national and international literature and, in particular, to illustrate the consequences for the mental health of those affected. First, relevant definitions are made and forms of appearance of emotional child maltreatment are presented. A comparison of national and global prevalences shows that emotional child maltreatment is one of the most prevalent forms of child maltreatment. There are different risk factors that can exist at the level of the parents as well as at the level of the children or the environment. The risk that children and adolescents who have experienced emotional violence will have experienced other forms of childmaltreatment is high.There aremultiple consequences for victims of emotional child maltreatment which can result in different, longterm participatory impairments. Especially the psychological and somatic consequences of emotional childmaltreatment can be compared to the consequences of child sexual abuse and physical child maltreatment. Nevertheless, the significance of emotional maltreatment for affected children and adolescents is still underestimated in practice. Often, the effects of emotionalmaltreatment on those affected are not visible. Froma child and adolescent psychiatric/ psychotherapeutic perspective, the psychological consequences must therefore be clearly stated. Finally, there is a need for a broader understanding of emotional child maltreatment that also includes peer and sibling violence.

Prevalence of violence against children in the United Kingdom: A systematic review and meta-analysis

BACKGROUND

Violence against children can have extensive, long-term, and far-reaching adverse impacts on survivors and society. There is currently little consensus in the United Kingdom around the prevalence of violence against children: maltreatment, intimate partner violence, sexual violence, bullying, and community violence, and most existing studies focus on only a single or a few forms of violence. This study aims to produce data to highlight the current magnitude of the problem in the UK, to inform policy, drive action and allow for monitoring of progress over time.

OBJECTIVE

To produce weighted prevalence estimates by violence type, as well as gender and age sub-categories, to give as full a picture as possible of the current prevalence of violence against children in the UK.

PARTICIPANTS AND SETTING

The prevalence of violence against children from 23 self-report studies conducted in the United Kingdom was gathered through a systematic review.

METHODS

Databases were searched from inception to 24th June 2022. Studies were reviewed systematically for appropriate data and meta-analyses were conducted to give pooled prevalence data based on a quality effects model.

RESULTS

The most prevalent self-reported experience of childhood violence was community violence at 27.33 % (95 % CI [9.84, 48.97]). Prevalence of bullying was also high at 22.75 % (95 % CI [13.25, 33.86]). The most prevalent forms of child maltreatment were domestic violence exposure at 11.9 % (95 % CI [6.34, 18.84]) and emotional maltreatment at 11.84 % (95 % CI [5.58, 19.89]).

CONCLUSION

National child maltreatment surveys are needed in the UK, using a comprehensive and conceptually robust approach, and valid and reliable instruments, to provide data for researchers and policymakers on the prevalence of all types of violence against children including exposure to multiple types. This allows monitoring of trends over time, can inform strategies for prevention, and can enable monitoring of future progress in reducing violence against children and its associated health and economic burden.

Severe outcomes following pediatric cannabis intoxication: a prospective cohort study of an international toxicology surveillance registry

INTRODUCTION

An increasing number of jurisdictions have legalized recreational cannabis for adult use. The subsequent availability and marketing of recreational cannabis has led to a parallel increase in rates and severity of pediatric cannabis intoxications. We explored predictors of severe outcomes in pediatric patients who presented to the emergency department with cannabis intoxication.

METHODS

In this prospective cohort study, we collected data on all pediatric patients (<18 years) who presented with cannabis intoxication from August 2017 through June 2020 to participating sites in the Toxicology Investigators Consortium. In cases that involved polysubstance exposure, patients were included if cannabis was a significant contributing agent. The primary outcome was a composite severe outcome endpoint, defined as an intensive care unit admission or in-hospital death. Covariates included relevant sociodemographic and exposure characteristics.

RESULTS

One hundred and thirty-eight pediatric patients (54% males, median age 14.0 years, interquartile range 3.7-16.0) presented to a participating emergency department with cannabis intoxication. Fifty-two patients (38%) were admitted to an intensive care unit, including one patient who died. In the multivariable logistic regression analysis, polysubstance ingestion (adjusted odds ratio = 16.3; 95% confidence interval: 4.6-58.3; P < 0.001)) and cannabis edibles ingestion (adjusted odds ratio = 5.5; 95% confidence interval: 1.9-15.9; P = 0.001) were strong independent predictors of severe outcome. In an age-stratified regression analysis, in children older than >10 years, only polysubstance abuse remained an independent predictor for the severe outcome (adjusted odds ratio 37.1; 95% confidence interval: 6.2-221.2; P < 0.001). As all children 10 years and younger ingested edibles, a dedicated multivariable analysis could not be performed (unadjusted odds ratio 3.3; 95% confidence interval: 1.6-6.7).

CONCLUSIONS

Severe outcomes occurred for different reasons and were largely associated with the patient's age. Young children, all of whom were exposed to edibles, were at higher risk of severe outcomes. Teenagers with severe outcomes were frequently involved in polysubstance exposure, while psychosocial factors may have played a role.

Child maltreatment and health service use: findings of the Australian Child Maltreatment Study

OBJECTIVES

To examine associations between child maltreatment and health service use, both overall, by type and by the number of types of maltreatment reported.

DESIGN, SETTING

Cross-sectional, retrospective survey using the Juvenile Victimization Questionnaire-R2: Adapted Version (Australian Child Maltreatment Study); computer-assisted mobile telephone interviews using random digit dialling, Australia, 9 April - 11 October 2021.

PARTICIPANTS

Australians aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16-24 years and 1000 respondents each from the five age groups (25-34, 35-44, 45-54, 55-64, 65 years or more).

MAIN OUTCOME MEASURES

Self-reported health service use during the past twelve months: hospital admissions, length of stay, and reasons for admission; and numbers of consultations with health care professionals, overall and by type. Associations between maltreatment and health service use are reported as odds ratios adjusted for age group, gender, socio-economic status, financial hardship (childhood and current), and geographic remoteness.

RESULTS

A total of 8503 participants completed the survey. Respondents who had experienced child maltreatment were significantly more likely than those who had not to report a hospital admission during the preceding twelve months (adjusted odds ratio [aOR], 1.39; 95% confidence interval [CI], 1.16-1.66), particularly admission with a mental disorder (aOR, 2.4; 95% CI, 1.03-5.6). The likelihood of six or more visits to general practitioners (aOR, 2.37; 95% CI, 1.87-3.02) or of a consultation with a mental health nurse (aOR, 2.67; 95% CI, 1.75-4.06), psychologist (aOR, 2.40; 95% CI, 2.00-2.88), or psychiatrist (aOR, 3.02; 95% CI, 2.25-4.04) were each higher for people who reported maltreatment during childhood. People who reported three or more maltreatment types were generally most likely to report greater health service use.

CONCLUSIONS

Child maltreatment has a major impact on health service use. Early, targeted interventions are vital, not only for supporting children directly, but also for their longer term wellbeing and reducing their health system use throughout life.

The prevalence of child maltreatment in Australia: findings from a national survey

OBJECTIVES

To estimate the prevalence in Australia of each type of child maltreatment; to identify gender- and age group-related differences in prevalence.

DESIGN, SETTING

Cross-sectional national survey; mobile telephone interviews using random digit dialling (computer-generated), Australia, 9 April - 11 October 2021. Retrospective self-report data using validated questionnaire (Juvenile Victimisation Questionnaire-R2 Adapted Version (Australian Child Maltreatment Study).

PARTICIPANTS

People aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16-24 years and 1000 respondents each from five further age groups (25-34, 35-44, 45-54, 55-64, 65 years or more).

MAIN OUTCOME MEASURES

Proportions of respondents reporting physical abuse, sexual abuse, emotional abuse, neglect, and exposure to domestic violence to age 18 years, assessed with the Juvenile Victimization Questionnaire-R2 Adapted Version (Australian Child Maltreatment Study), overall and by gender and age group, and weighted to reflect characteristics of the Australian population aged 16 years or more in 2016.

RESULTS

Complete survey data were available for 8503 eligible participants (14% response rate). Physical abuse was reported by 32.0% of respondents (95% confidence interval [CI], 30.7-33.3%), sexual abuse by 28.5% (95% CI, 27.3-29.8%), emotional abuse by 30.9% (95% CI, 29.7-32.2%), neglect by 8.9% (95% CI, 8.1-9.7%), and exposure to domestic violence by 39.6% (95% CI, 38.3-40.9%). The proportions of respondents who reported sexual abuse, emotional abuse, or neglect were each statistically significantly larger for women than men. The reported prevalence of physical abuse by respondents aged 16-24 years was lower than for those aged 25-34 years, and that of sexual abuse was lower than for those aged 35-44 years, suggesting recent declines in the prevalence of these maltreatment types.

CONCLUSIONS

Child maltreatment is common in Australia, and larger proportions of women than men report having experienced sexual abuse, emotional abuse, and neglect during childhood. As physical and sexual abuse may have declined recently, public health policy and practice may have positive effects, justifying continued monitoring and prevention activities.

The prevalence and nature of multi-type child maltreatment in Australia

OBJECTIVES

To determine the prevalence in Australia of multi-type child maltreatment, defined as two or more maltreatment types (physical abuse, sexual abuse, emotional abuse, neglect, or exposure to domestic violence) and to examine its nature, family risk factors, and gender and age cohort differences.

DESIGN

Retrospective cross-sectional survey using a validated questionnaire.

SETTING AND PARTICIPANTS

Mobile phone random digit-dial sample of the Australian population aged 16 years and older.

MAIN OUTCOME MEASURES

National estimates of multi-type child maltreatment up to age 18 years using the Juvenile Victimisation Questionnaire-R2: Adapted Version (Australian Child Maltreatment Study).

RESULTS

Of 8503 participants, 62.2% (95% CI, 60.9-63.6%) experienced one or more types of child maltreatment. Prevalence of single-type maltreatment was 22.8% (95% CI, 21.7-24.0%), whereas 39.4% (95% CI, 38.1-40.7%) of participants reported multi-type maltreatment and 3.5% (95% CI, 3.0-4.0%) reported all five types. Multi-type maltreatment was more common for gender diverse participants (66.1% [95% CI, 53.7-78.7%]) and women (43.2% [95% CI, 41.3-45.1%]) than for men (34.9% [95% CI, 33.0-36.7%]). Multi-type maltreatment prevalence was highest for those aged 25-44 years. Family-related adverse childhood experiences - especially mental illness and alcohol or substance misuse - increased risk. Exposure to domestic violence was the maltreatment type most often present in multi-type maltreatment patterns.

CONCLUSIONS

Multi-type child maltreatment is prevalent in Australia and more common in women and gender diverse individuals. Child protection services, health practitioners, and prevention and intervention services must assess and manage multi-type maltreatment in children and address its health consequences across the lifespan. Public health policy should consider prevention services or strategies that target multi-type child maltreatment.

The Australian Child Maltreatment Study (ACMS), a national survey of the prevalence of child maltreatment and its correlates: methodology

OBJECTIVES

To describe the aims, design, methodology, and respondent sample representativeness of the Australian Child Maltreatment Study (ACMS).

DESIGN, SETTING

Cross-sectional, retrospective survey; computer-assisted mobile telephone interviewing using random digit dialling (computer-generated), Australia, 9 April - 11 October 2021.

PARTICIPANTS

People aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16-24 years and 1000 respondents each from five further age groups (25-34, 35-44, 45-54, 55-64, 65 years or more).

MAIN OUTCOME MEASURES

Primary outcomes: Emotional abuse, neglect, physical abuse, sexual abuse, exposure to domestic violence during childhood, assessed with the Juvenile Victimization Questionnaire-R2 Adapted Version (Australian Child Maltreatment Study).

SECONDARY OUTCOMES

selected mental disorder diagnoses (Mini International Neuropsychiatric Interview, MINI), selected physical health conditions, health risk behaviours, health service use.

RESULTS

The demographic characteristics of the ACMS sample were similar to those of the Australian population in 2016 with respect to gender, Indigenous status, region and remoteness category of residence, and marital status, but larger proportions of participants were born in Australia, lived in areas of higher socio-economic status, had tertiary qualifications, and had income greater than $1250 per week. Population weights were derived to adjust for these differences. Associations between the number of calls required to recruit participants and maltreatment rates and health outcomes were not statistically significant.

CONCLUSIONS

The ACMS provides the first reliable estimates of the prevalence of each type of child maltreatment in Australia. These estimates, and those of associated mental health and health risk behaviours reported in this supplement can inform policy and practice initiatives for reducing the prevalence of child maltreatment and its consequences. Our benchmark study also provides baseline data for repeated waves of the ACMS that will assess the effectiveness of these initiatives.
