Childhood maltreatment and high dietary fat intake behaviors in adulthood: A birth cohort study

Childhood maltreatment has been associated with a wide range of chronic medical conditions including obesity, other metabolic events and eating disorders. However, little is known about the association between childhood maltreatment and high dietary fat intake. This study addresses the extent to which co-occurring and specific forms of substantiated childhood maltreatment are associated with self-reported high dietary fat intake in adulthood and whether there is a gender–childhood maltreatment interaction in predicting this association. The study also examines the association between age at substantiation of maltreatment, number of childhood maltreatment substantiations and high dietary fat intake-related behaviors. The data were from a prospective Australian pre-birth mother-child dyads study, the Mater-University of Queensland Study of Pregnancy. The study followed 7223 mother-child dyads following the birth of a live, singleton baby at the Mater hospital. Recruitment was early in pregnancy, and then follow-ups at 3–5 days postpartum and again when the child was 6 months, 5, 14 and 21 years of age. The data were linked to agency-substantiated cases of childhood maltreatment 0–14 years. This study extended the data linkage to 3766 (47.4% female) participants who had complete data on dietary fat intake behaviors at the 21-year follow-up. Consecutive logistic regressions were used to estimate odds ratios with respective 95% confidence intervals for high dietary fat intake for multiple and specific forms of childhood maltreatment, as well as age at and number of childhood maltreatment substantiations. Finally, a gender–childhood maltreatment interaction term was used to predict the outcome. In both unadjusted and adjusted analyses, substantiated childhood maltreatment including physical abuse were associated with high dietary fat intake-related behaviors. Similarly, substantiation of childhood maltreatment between the ages of 5 and 14 years was significantly associated with high dietary fat intake-related behaviors as were two or more substantiations of maltreatment. Inclusion of gender–childhood maltreatment interaction only had a minor impact on the size and direction of the association. Chronic and severe forms of childhood maltreatment including physical abuse are associated with a higher rate of dietary fat intake in young adulthood. Further research to replicate this association might focus on possible neuro-hormonal mechanisms that might explain this behavior.     

Child maltreatment and attentional problems: A longitudinal birth cohort study

ObjectiveTo examine whether child maltreatment is associated with attentional problems in adolescence (14 years) and young adulthood (21 years), and whether outcomes depend on the type of maltreatment (sexual vs non-sexual).MethodsData from a population based cohort study involving 3778 mother-child pairs were linked with data from the state child protection agency to examine associations between child abuse and neglect and attention problems, measured using the Achenbach Child Behaviour Checklist (CBCL) and the Achenbach Young Adult Self Report (YASR).Results245 (6.5%) participants had been the subject of notification for non-sexual maltreatment (one or more of neglect, emotional or physical abuse) compared with only 54 (1.4%) who had been subject of notification for suspected sexual abuse. After adjusting for potential confounding variables including maternal, participant and sociodemographic factors, we found those exposed to non sexual maltreatment were likely to experience attentional problems at 14 years (p < .001) and 21 years of age (p = .044), compared with those participants who had not experienced non sexual maltreatment. By contrast, at age 14 years, sexual abuse was associated with attentional problems only as reported by the participant, not their carer. Results at 21 years of age for those exposed to sexual child maltreatment (p=.655) were again in contrast to the observed association between attentional problems and non sexual child maltreatment (p = .035).ConclusionIn this study, non-sexual maltreatment in childhood is associated with attentional problems at both 14 years and 21 years of age. These findings highlight the need for targeted research to better understand the longer term mental health outcomes for children exposed to non-sexual maltreatment. Potential implications for mental health services include the need for broader screening at presentation and importantly, greater collaboration with schools, general practitioners and paediatricians, given the greatest impact would arguably be within these settings.     

Girls in residential care: From child maltreatment to trauma-related symptoms in emerging adulthood

The current study examined the association between child maltreatment and trauma-related symptoms in emerging adulthood – over and above the incidence of such symptoms and conduct problems during adolescence – among a sample of female adolescents in residential care. This study used data from a longitudinal study. The sample was composed of 89 adolescent females who were first interviewed at time of admission in a residential center (M_age = 15.33 years, SD = 1.31) and later in young adulthood (M_age = 19.27, SD = 1.55). At time 1, trauma-related symptoms were assessed with the Trauma Symptom Checklist for Children and conduct problems with a composite measure. At time 2, child maltreatment was assessed retrospectively with the Childhood Trauma Questionnaire, and trauma-related symptoms were reassessed with the Trauma Symptom Inventory-2. Results indicated that child maltreatment, especially emotional abuse and neglect, was related to anxious arousal, depression, and anger in emerging adulthood. This study showed that females from our sample often reported different types of maltreatment during childhood and that these traumatic experiences were significantly associated with poor adult psychological functioning.     

Educational and emotional health outcomes in adolescence following maltreatment in early childhood: A population-based study of protective factors

Although childhood maltreatment is associated with long-term impairment, some children function well despite this adversity. This study aimed to identify the key protective factors for good educational attainment and positive emotional health in adolescents who experienced maltreatment in early childhood. Data were analyzed from the Avon Longitudinal Study of Parents and Children, a large UK prospective cohort study. The sample was defined by maternally reported exposure to physical or emotional maltreatment by a parent prior to 5 years. 1118 (8.0%) children were emotionally maltreated and 375 (2.7%) were physically maltreated before the age of 5. There were too few cases of sexual abuse to be considered. Positive outcomes were operationalized as achieving 5 or more grade A*-C GCSE exam grades at 16 years and scores above the cohort median on the self-report Warwick-Edinburgh Mental Wellbeing Scale and Bachmann Self-Esteem Scale at 17.5 years. The associations of individual, family and community covariates with successful adaptation to the adversity of maltreatment were investigated using logistic regression.School related factors, including engagement in extracurricular activities, satisfaction with school and not being bullied were the most important in facilitating resilience in educational attainment, self-esteem and wellbeing. Good communication and social skills was the most protective individual trait. There was insufficient evidence to suggest that family factors were associated with resilience to maltreatment. School-based interventions are recommended to promote positive adaptation following parental maltreatment. Future research should evaluate outcomes across the life-course to understand whether the protective influences of school persist into adulthood.     

The association between childhood maltreatment experiences and the onset of maltreatment perpetration in young adulthood controlling for proximal and distal risk factors

The evidence for association between child maltreatment victimization and later maltreatment perpetration is both scant and mixed. The objective of the present study was to assess the association between childhood maltreatment experiences and later perpetration of maltreatment in young adulthood controlling for proximal young adult functioning, prior youth risk behaviors, and childhood poverty. The study included 6,935 low-income children with (n = 4,470) or without (n = 2,465) maltreatment reports prior to age 18 followed from ages 1.5 through 11 years through early adulthood (ages 18–26). Administrative data from multiple regional and statewide agencies captured reports of maltreatment, family poverty and characteristics, system contact for health, behavioral risks and mental health in adolescence, and concurrent adult functioning (crime, mental health and poverty). After controlling for proximal adult functioning, repeated instances of neglect or mixed type maltreatment remained associated with young adult perpetration. Females and subjects with adolescent history of runaway, violent behaviors or non-violent delinquency also had higher risk. Greater caregiver education remained associated with reduced risk. The study concludes that prevention of recurrent neglect and mixed forms of maltreatment may reduce risk of maltreatment for future generations. Intervening to increase parental education and decrease adolescent risk behaviors may offer additional benefit.     

Adverse childhood experiences: Prevalence and related factors in adolescents of a Brazilian birth cohort

Adverse childhood experiences (ACEs) can affect people's health and wellbeing not only at the time the ACE is experienced, but also later in life. The majority of studies on ACEs are carried out in high-income countries and little is known about its prevalence in low and middle-income countries. Thus, the aim of this study was to assess the prevalence of ACEs, associations between ACEs and sociodemographic factors, and the interrelationship between types of ACEs in adolescents of a Brazilian birth cohort. Data from 3,951 adolescents (78.4% of the original cohort) from the 1993 Pelotas Cohort were analyzed. Seven types of ACEs were assessed in those up to 18 years old: physical abuse, sexual abuse, physical neglect, emotional neglect, domestic violence, parental separation and parental death. The most common ACE was parental separation (42%), followed by emotional neglect (19.7%) and domestic violence (10.3%). Approximately 85% of the adolescents experienced at least one ACE, and females reported a higher number of adversities. Several socioeconomic, demographic and family-related characteristics were associated with the occurrence of ACEs, e.g. non-white skin color, low family income, low maternal schooling, absence of mother's partner, maternal smoking, and poor maternal mental health. A strong interrelationship was observed among the ACEs, indicating clustering of risk. These aspects should be considered by health and social care professionals in the prevention and identification of childhood adversities.     

Developmental effects of childhood household adversity,transitions, and relationship quality on adult outcomes of socioeconomic status: Effects of substantiated child maltreatment

The degree to which child maltreatment interacts with other household adversities to exacerbate risk for poor adult socioeconomic outcomes is uncertain. Moreover, the effects of residential, school, and caregiver transitions during childhood on adult outcomes are not well understood. This study examined the relation between household adversity and transitions in childhood with adult income problems, education, and unemployment in individuals with or without a childhood maltreatment history. The potential protective role of positive relationship quality in buffering these risk relationships was also tested. Data were from the Lehigh Longitudinal Study (n = 457), where subjects were assessed at preschool, elementary, adolescent, and adult ages. Multiple group path analysis tested the relationships between childhood household adversity; residential, school, and caregiver transitions; and adult socioeconomic outcomes for each group. Caregiver relationship quality was included as a moderator, and gender as a covariate. Household adversity was negatively associated with education level and positively associated with income problems for non-maltreated children only. For both groups, residential transitions was negatively associated with education level and caregiver transitions was positively associated with unemployment problems. Relationship quality was positively associated with education level only for non-maltreated children. For children who did not experience maltreatment, reducing exposure to household adversity is an important goal for prevention. Reducing exposure to child maltreatment for all children remains an important public health priority. Results underscore the need for programs and policies that promote stable relationships and environments.     

From childhood emotional maltreatment to depressive symptoms in adulthood: The roles of self-compassion and shame

BackgroundEmotional abuse is a form of maltreatment that most strongly predicts adult depressive symptoms in community samples. Introject theories suggest that some depressive symptoms stem from survivors having learned to treat themselves the way they were treated by their perpetrators.ObjectiveMalevolent introjects may undermine self-compassion, which may subsequently maintain feelings of shame. Thus, we hypothesized that self-compassion and shame would mediate the path from retrospective reports of maltreatment to concurrent depressive symptoms in adulthood.Participants and SettingParticipants were 244 adult community members and college students living in a Southwestern American metroplex.MethodWe ran a multiple mediator path model with emotional abuse as the independent variable. We specified four covariates: physical abuse, sexual abuse, physical neglect, and emotional neglect, and held constant the variance they explained in self-compassion, shame, and depression.ResultsOur final model accounted for 53.1% of the variance in adult depressive symptoms. A significant indirect effect from emotional abuse passed through both mediators and ended in adult depressive symptoms. We also found an indirect path from emotional neglect to depression passing through both mediators.ConclusionsIt appears emotional abuse and emotional neglect can undermine the formation of self-compassion. Low self-compassion predicts greater shame and depressive symptoms. Our model suggests self-compassion may be a particularly effective intervention point for survivors of emotional maltreatment.     

Protective factors associated with resilient functioning in young adulthood after childhood exposure to violence

Children may be subjected to many forms of violence and a significant number will experience multiple victimizations. These children are at high risk for developing psychological and emotional difficulties that may last into adulthood. Despite the increased risk for psychopathology, a substantial percentage of young adults exhibit resilient functioning following a history of childhood violence. This study examines the role of social support, spirituality, and emotional intelligence in promoting resilience during emerging adulthood. Participants included 321 young adult American college students, age 18–24, who experienced childhood violence, including community violence, interpersonal aggression, child maltreatment, peer/sibling victimization, and/or sexual assault. Findings revealed that this sample was highly victimized, with an average of 9 violent experiences reported during childhood. Hierarchical multiple regression analyses indicated that after controlling for exposure to childhood victimization, other potentially traumatic events, and current depression and anxiety symptoms, higher resilience during emerging adulthood was associated with greater spirituality, greater emotional intelligence, and support from friends (but not from family). Findings suggest that the potency of protective factors outweighs that of adversity and psychopathology when predicting resilient functioning. By identifying variables that can enhance resilience, this study offers unique insight into how functioning may be improved by both individual and environmental factors.     

Intergenerational transmission of out-of-home care in Sweden: A population-based cohort study

The objective of this study is to examine the intergenerational transmission of out-of-home care. This population-based study used data from the Swedish National Registers and included all children born in Sweden between 1990 and 2012 (followed for up to 13 years), whose parents were both born in Sweden between 1973 and 1980 (278 327 children; 145 935 mothers; 146 896 fathers). Cox regression models are used to obtain crude and adjusted hazard ratios (HR) of OHC placement among children based on parents’ history of OHC. Compared with children whose parents both did not have a history of OHC, the risk of being placed in OHC was greater when both parents spent time in OHC (crude HR = 48.70, 95% CI 41.46–57.21; adjusted HR = 3.04, 95% CI = 2.54–3.64), however, children who had only one parent who spent time in care were also at higher risk (mothers only adjusted HR = 2.37, 95% CI = 2.08–2.70; fathers only adjusted HR = 1.33, 95% CI = 1.13–1.55). The crude rate of placement in OHC was highest for children whose parents were placed in care during adolescence, but after adjusting for social and behavioral covariates, children whose parents were in care in early childhood were at greater risk of OHC than children whose parents were in care in adolescence. To reduce this intergenerational transmission of OHC, more supports should be provided to parents who spent time in OHC to ensure a successful transition to parenthood.     

Maternal history of child maltreatment and maternal depression risk in the perinatal period: A longitudinal study

Existing research is limited, with only a few studies considering each single type and multiple types of child maltreatment (CM) as well as multiple assessments of maternal depression throughout the perinatal period. The purpose of the study was to assess each type and accumulative types of CM in relation to the risk of maternal depression throughout the perinatal period. In total, 276 pregnant women were recruited from the prenatal clinic at a general hospital in China. Maternal CM history and depression risk were assessed at late pregnancy, postpartum week 1, and postpartum week 4 using the Childhood Trauma Questionnaire (CTQ) and Edinburgh Postnatal Depression Scale (EPDS). The GEE showed that physical and emotional neglect and multiple types of CM were associated with higher overall depression risk across the perinatal period. The multinomial regression models showed physical neglect and multiple types of CM predicted higher risk of both antepartum and postpartum depression. Emotional and sexual abuse and emotional neglect predicted antepartum depression risk, while none of the three types of CM predicted postpartum depression risk. Physical abuse did not predict antepartum and postpartum depression risk. The findings suggest that maternal history of child physical and emotional neglect play significant roles in perinatal depression risk with physical neglect as the most important predictor. Routine screening for maternal CM history and depression risk in prenatal clinics is needed to aid in the early detection and treatment of depression.     

Paternity establishment at birth and early maltreatment: Risk and protective effects by maternal race and ethnicity

BackgroundMinority race/ethnicity, low socioeconomic status, and lack of established paternity have been identified in previous research as risk factors for child maltreatment. However, given vastly different patterns of income distribution, single parenting and co-parenting across racial and ethnic populations, it is difficult to know which of these factors contribute most to maltreatment risk.ObjectiveThe current study explores whether the odds of maltreatment differ across race/ethnicity when paternity is not established at birth after controlling for maternal socioeconomic status.MethodsUsing merged birth certificate and child protective services records for children born between 2009 and 2011 in Texas (N = 1,175,804), we conducted multiple logistic regression analyses testing the main effects of maternal race and lack of established paternity, as well as the interaction of the two, on substantiated maltreatment.ResultsResults show that children of black mothers were less likely to have established paternity and more likely to experience maltreatment compared with other groups. However, the odds of maltreatment were lower for children of black mothers without established paternity compared to children of white mothers without established paternity (OR = .71, 95% CI [0.67,0.75]). Alternatively, the odds of maltreatment were higher when paternity was not established at birth for Hispanic mothers (OR = 1.13, 95% CI [1.08,1.18]) and mothers of other race/ethnicities (OR = 1.35, 95% CI [1.11,1.65]) compared to white mothers.ConclusionResearch and prevention programming must consider that the processes and pathways linking paternity establishment and maltreatment may differ within and between racial/ethnic groups.     

Childhood maltreatment in South Korea: retrospective study

Objective

This study explored the prevalence of childhood maltreatment in South Korea using the retrospective version of ICAST and the associations between perceptions of abuse experienced during childhood and recent interpersonal problems and depression.

Methods

539 young persons, aged 18–24 years, from various universities, work places, and clinical settings participated in a study using the ISPCAN Child Abuse Screening Tool-Retrospective Version (ICAST-R), the short form of the Korean-Inventory of Interpersonal Problems Circumplex Scale (KIIP-SC), and the Korean version of the Beck Depression Inventory (K-BDI).

Results

While males reported more physical abuse, females reported being exposed to more emotional or sexual abuse. The proportion of reported extra-familial or peer abuse was relatively high. Interpersonal problems and depression were significantly high for those who experienced all types of abuse during childhood. Perception of physical abuse as reasonable/justified discipline affected interpersonal problems and perception of emotional abuse when compared to peers affected interpersonal problems and depression. Unlike previous studies, this study identified more depressive symptoms reported with disclosure of sexual abuse.

Practice implications

These findings highlight the importance of understanding how one perceives maltreatment. Perceiving an abusive act as a justifiable disciplinary method may affect reporting as well as longer term consequences for the victim. A wide range of perpetrators and different settings in which maltreatment may occur must be considered as influencing these perceptions. This study contributed to the determination of validity of the ICAST-R for use in wider population surveys.     

Perspectives on trauma-informed care from mothers with a history of childhood maltreatment: A qualitative study

Women who experienced abuse or neglect as children are more likely to have health problems during pregnancy and postpartum, but can be reluctant to seek help due to a lack of trauma-informed services. As part of a larger mixed method study, this component aimed to obtain qualitative data from trauma-exposed new mothers about their health care preferences during the perinatal period with the ultimate goal to design personalized, supportive interventions. Fifty-two trauma-exposed mothers completed a semi-structured interview at seven months postpartum about health care preferences including ideas for programs that promote wellness, thoughts about the influences of being a new mother and possible names for a program serving trauma-exposed mothers. Interviews were transcribed and coded using N-Vivo. Participants described ambivalence about seeking help but also a sincere desire for healing, coupled with hope for the future. This tension was apparent in the discussions highlighting the importance of access to experienced, nonjudgmental, and knowledgeable health and social care staff and volunteers, the wish for both formal, integrated physical and mental health services, and for informal opportunities to meet other trauma-exposed mothers in a non-stigmatizing, child-friendly setting. Finally, positive relationship-building, respect, and safety were identified as key elements of services critical to counteract trauma-related shame and mistrust in others. Services for trauma-exposed mothers should acknowledge the normal ambivalence surrounding seeking help, but promote hope-affirming practices in a family-centered, safe, non-clinical setting that involves children, builds social support, and provides peer interaction. Program names should reflect optimism and healing rather than trauma.     

Cumulative childhood maltreatment and its dose-response relation with adult symptomatology: Findings in a sample of adult survivors of sexual abuse

In the present study, we examined the role of cumulative childhood maltreatment experiences for several health related outcomes in adulthood, including symptoms of psychological distress as well as perceived social support and hardiness. The sample comprised adult survivors of sexual abuse (N = 278, 95.3% women, mean age at first abusive incident = 6.4 years). One-way ANOVAs revealed a statistically significant dose-response relation between cumulative childhood maltreatment scores and self-reported symptoms of posttraumatic stress (PTSS), anxiety, depression, eating disorders, dissociation, insomnia, nightmare related distress, physical pain, emotional pain, relational problems, self-harm behaviors as well as on a measure of symptom complexity. Cumulative childhood maltreatment was also associated with lower levels of work functioning. An inverse dose-response relation was found for perceived social support and hardiness. Using a Bonferroni corrected alpha level, cumulative childhood maltreatment remained significantly associated with all outcome measures with the exception of eating disorder symptoms after controlling for abuse-related independent variables in hierarchical regression analyses. Results add to previous literature by showing that dose-response relation between cumulative childhood adversities and adult symptom outcomes could also be identified in a sample characterized by high exposure to adversities, and lends support to the notion put forth by previous authors that cumulative childhood adversities seem to be related to the severity of adult health outcomes in a rule-governed way.     

Impacts of adverse childhood experiences on health,mental health,and substance use in early adulthood: A cohort study of an urban,minority sample in the U.S.

Research has shown that adverse childhood experiences (ACEs) increase the risk of poor health-related outcomes in later life. Less is known about the consequences of ACEs in early adulthood or among diverse samples. Therefore, we investigated the impacts of differential exposure to ACEs on an urban, minority sample of young adults. Health, mental health, and substance use outcomes were examined alone and in aggregate. Potential moderating effects of sex were also explored. Data were derived from the Chicago Longitudinal Study, a panel investigation of individuals who were born in 1979 or 1980. Main-effect analyses were conducted with multivariate logistic and OLS regression. Sex differences were explored with stratified analysis, followed by tests of interaction effects with the full sample. Results confirmed that there was a robust association between ACEs and poor outcomes in early adulthood. Greater levels of adversity were associated with poorer self-rated health and life satisfaction, as well as more frequent depressive symptoms, anxiety, tobacco use, alcohol use, and marijuana use. Cumulative adversity also was associated with cumulative effects across domains. For instance, compared to individuals without an ACE, individuals exposed to multiple ACEs were more likely to have three or more poor outcomes (OR range = 2.75–10.15) and four or more poor outcomes (OR range = 3.93–15.18). No significant differences between males and females were detected. Given that the consequences of ACEs in early adulthood may lead to later morbidity and mortality, increased investment in programs and policies that prevent ACEs and ameliorate their impacts is warranted.     

Renovating early childhood education pedagogy: a case study in Vietnam

Since 2003, the Vietnamese government has prioritised curriculum reform efforts and commitment to improving the quality of the national curriculum. The Vietnamese early childhood education renovation has encountered considerable changes and challenges, particularly in the area of pedagogical approaches. Many early childhood teachers continue to favour direct instruction over more appropriate teaching practices for early childhood. This paper reviews the implementation and renovation of the revised curriculum over the past 10 years in Vietnam, and examines the changing realities of early childhood teachers' work to explore ways to implement and sustain changes in pedagogy in Lam Dong Province, Vietnam. The paper explores how changing societal expectations and the changing educational philosophies and resultant pedagogy have impacted on the beliefs and practices of early childhood teachers. The teaching profession, as a whole, is facing ongoing change and challenge; not only are ongoing educational reforms redefining teachers' work, but increasing teacher attrition and turnover also creates problems for Early Childhood Education and Care (ECEC) in Lam Dong province. The paper concludes with suggestions for areas for future research in Vietnam in the field of ECEC.     

What troubles early childhood educators in New Zealand: a 20-year cross-sectional study of ethical difficulties in early childhood practice

For more than 20 years, the New Zealand early childhood (EC) sector has had guidance about how to deal with situations of ethical difficulty in daily practice through the ECE Code of Ethics. This paper reports on three surveys undertaken at 10-year intervals that sought to understand EC educators’ experiences of such situations, and how they addressed them within their EC settings. An analysis of educators’ stories of ethically troubling situations from the three data-sets traced shifts and similarities in the content reported, and in how educators responded to these challenges over the two-decade period. We situate this analysis alongside changes in the New Zealand ECE policy context during the same time frame. We argue that a connection exists between the reported situations and teachers’ responses to them, and changes within the policy and professional context of daily EC practice.     

Development of a prediction model for child maltreatment recurrence in Japan: A historical cohort study using data from a Child Guidance Center

To develop a prediction model for the first recurrence of child maltreatment within the first year after the initial report, we carried out a historical cohort study using administrative data from 716 incident cases of child maltreatment (physical abuse, psychological abuse, or neglect) not receiving support services, reported between April 1, 1996 through March 31, 2011 to Shiga Central Child Guidance Center, Japan. In total, 23 items related to characteristics of the child, the maltreatment, the offender, household, and other related factors were selected as predictive variables and analyzed by multivariate logistic regression model for association with first recurrence of maltreatment. According to the stepwise selection procedure six factors were identified that include 9–13 year age of child (AOR = 3.43/95%CI = 1.52−7.72), <40 year age of the offender (AOR = 1.65/95%CI = 1.09−2.51), offender’s history of maltreatment during childhood (AOR = 2.56/95%CI = 1.31−4.99), household financial instability or poverty (AOR = 1.64/95%CI = 1.10−2.45), absence of someone in the community who could watch over the child (AOR = 1.68/95%CI = 1.16−2.44), and the organization as the referral source (AOR = 2.21/95%CI = 1.24−3.93). Using these six predictors, we generated a linear prediction model with a sensitivity and specificity of 45.2% and 82.4%, respectively. The model may be useful to assess the risk of further maltreatment and help the child and family welfare administrations to develop preventive strategies for recurrence.     

The impact of child maltreatment on the risk of deliberate self-harm among adolescents: A population-wide cohort study using linked administrative records

Adolescents exposed to maltreatment have an elevated risk of deliberate self-harm (DSH). The aim of this study was to investigate longitudinally the effects of the number, timing, and type of maltreatment allegations on adolescent risk of having a DSH-related hospital admission, using linked data in Western Australia. A total of 351,372 children born between 1986 and 2000 were followed from birth up to the year 2010. Cox regression models were utilized, while controlling for a range of psychosocial covariates. Compared to children without allegations of maltreatment, children with unsubstantiated allegations only (aHR = 1.04, 95%CI: 1.00–1.08, p < .01) and children with a substantiated allegation (aHR = 1.10, 95%CI: 1.06–1.15, p < .001) all had significantly increased risk of DSH in adolescence. Among children with a substantiated allegation of maltreatment, the greater the number of allegations, the longer the exposure to maltreatment, and the more types of maltreatment experienced by a child, the higher the child's risk of DSH. However, this dose–response pattern was not found among children with unsubstantiated allegations only. This study calls for the early identification of children who are vulnerable to maltreatment, the better identification of the duration and severity of maltreatment experiences, and the provision of continued care and support, to reduce the child's DSH risk in adolescence.
