RESUMO
OBJECTIVES: The rate of mental health services provided to children and young people is increasing worldwide, including in Australia. The aim of this study was to describe patterns of hospital and ambulatory mental health service use among a large population cohort of adolescents followed from birth, with consideration of variation by age, sex and diagnosis. METHODS: Characteristics of services provided for children with mental disorder diagnoses between birth and age 17.5 years were ascertained for a population cohort of 85,642 children (52.0% male) born between 2002 and 2005, from 'Admitted Patients', 'Emergency Department' and 'Mental Health Ambulatory' records provided by the New South Wales and Australian Capital Territory Health Departments. RESULTS: A total of 11,205 (~13.1%) children received at least one hospital or ambulatory health occasion of service for a mental health condition in the observation period. More than two-fifths of children with mental disorders had diagnoses spanning multiple categories of disorder over time. Ambulatory services were the most heavily used and the most common point of first contact. The rate of mental health service contact increased with age across all services, and for most categories of mental disorder. Girls were more likely to receive services for mental disorders than boys, but boys generally had an earlier age of first service contact. Finally, 3.1% of children presenting to mental health services experienced involuntary psychiatric inpatient admission. CONCLUSIONS: The extent of hospital and ambulatory-based mental healthcare service among children emphasises the need for primary prevention and early intervention.
RESUMO
BACKGROUND: Air pollution has been linked to a variety of childhood mental health problems, but results are inconsistent across studies and the effect of exposure timing is unclear. We examined the associations between air pollution exposure at two time-points in early development and psychotic-like experiences (PLEs), and emotional and conduct symptoms, assessed in middle childhood (mean age 11.5 years). METHODS: Participants were 19,932 children selected from the NSW Child Development Study (NSW-CDS) with available linked multi-agency data from birth, and self-reported psychotic-like experiences (PLEs) and psychopathology at age 11-12 years (middle childhood). We used binomial logistic regression to examine associations between exposure to nitrogen dioxide (NO2) and particulate matter less than 2.5 µm (PM2.5) at two time-points (birth and middle childhood) and middle childhood PLEs, and emotional and conduct symptoms, with consideration of socioeconomic status and other potential confounding factors in adjusted models. RESULTS: In fully adjusted models, NO2 exposure in middle childhood was associated with concurrent PLEs (OR = 1.10, 95% CI = 1.02-1.20). Similar associations with PLEs were found for middle childhood exposure to PM2.5 (OR = 1.05, 95% CI = 1.01-1.09). Neither NO2 nor PM2.5 exposure was associated with emotional symptoms or conduct problems in this study. CONCLUSIONS: This study highlights the need for a better understanding of potential mechanisms of action of NO2 in the brain during childhood.

BACKGROUND: Psychiatric illness is a well-established risk factor for criminal justice system involvement, but less is known about the relationships between specific psychiatric illnesses and reoffending. Research typically examines reoffending as a single discrete event. We examined the relationship between different psychiatric disorders and types of reoffending while accounting for multiple reoffending events over time. METHODS: Data were drawn from a population cohort of 83,039 individuals born in Queensland, Australia, in 1983 and 1984 and followed to age 29-31 years. Psychiatric diagnoses were drawn from inpatient health records and offending information was drawn from court records. Descriptive and recurrent event survival analyses were conducted to examine the association between psychiatric disorders and reoffending. RESULTS: The cohort included 26,651 individuals with at least one proven offence, with 3,580 (13.4%) of these individuals also having a psychiatric disorder. Individuals with any psychiatric disorder were more likely to reoffend compared to those without a disorder (73.1% vs. 56.0%). Associations between psychiatric disorders and reoffending varied across age. Individuals with a psychiatric disorder only started to accumulate more reoffending events from ~ 27 years, which accelerated up to age 31 years. There were both specificity and common effects in the associations between different psychiatric disorders and types of reoffending. CONCLUSIONS: Findings demonstrate the complexity and temporal dependency of the relationship between psychiatric illness and reoffending. These results reveal the heterogeneity present among individuals who experience psychiatric illness and contact with the justice system, with implications for intervention delivery, particularly for those with substance use disorders.

OBJECTIVE: We investigated patterns of service contact for self-harm and suicidal ideation recorded by a range of human service agencies - including health, police and child protection - with specific focus on overlap and sequences of contacts, age of first contact and demographic and intergenerational characteristics associated with different service responses to self-harm. METHODS: Participants were 91,597 adolescents for whom multi-agency linked data were available in a longitudinal study of a population cohort in New South Wales, Australia. Self-harm and suicide-related incidents from birth to 18 years of age were derived from emergency department, inpatient hospital admission, mental health ambulatory, child protection and police administrative records. Descriptive statistics and binomial logistic regression were used to examine patterns of service contacts. RESULTS: Child protection services recorded the largest proportion of youth with reported self-harm and suicidal ideation, in which the age of first contact for self-harm was younger relative to other incidents of self-harm recorded by other agencies. Nearly 40% of youth with a health service contact for self-harm also had contact with child protection and/or police services for self-harm. Girls were more likely to access health services for self-harm than boys, but not child protection or police services. CONCLUSION: Suicide prevention is not solely the responsibility of health services; police and child protection services also respond to a significant proportion of self-harm and suicide-related incidents. High rates of overlap among different services responding to self-harm suggest the need for cross-agency strategies to prevent suicide in young people.

PURPOSE: To investigate relationships between distinct schizotypy risk profiles in childhood and the full spectrum of parental mental disorders. METHODS: Participants were 22,137 children drawn from the New South Wales Child Development Study, for whom profiles of risk for schizophrenia-spectrum disorders in middle childhood (age ~ 11 years) were derived in a previous study. A series of multinomial logistic regression analyses examined the likelihood of child membership in one of three schizotypy profiles (true schizotypy, introverted schizotypy, and affective schizotypy) relative to the children showing no risk, according to maternal and paternal diagnoses of seven types of mental disorders. RESULTS: All types of parental mental disorders were associated with membership in all childhood schizotypy profiles. Children in the true schizotypy group were more than twice as likely as children in the no risk group to have a parent with any type of mental disorder (unadjusted odds ratio [OR] = 2.27, 95% confidence intervals [CI] = 2.01-2.56); those in the affective (OR = 1.54, 95% CI = 1.42-1.67) and introverted schizotypy profiles (OR = 1.39, 95% CI = 1.29-1.51) were also more likely to have been exposed to any parental mental disorder, relative to children showing no risk. CONCLUSION: Childhood schizotypy risk profiles appear not to be related specifically to familial liability for schizophrenia-spectrum disorders; this is consistent with a model where liability for psychopathology is largely general rather than specific to particular diagnostic categories.

OBJECTIVES: Childhood disturbances in social, emotional, language, motor and cognitive functioning, and schizotypy have each been implicated as precursors of schizophrenia-spectrum disorders. We investigated whether relationships between early childhood developmental vulnerabilities and childhood schizotypy are mediated by educational underachievement in middle childhood. METHODS: Participants were members of a large Australian (n = 19,216) population cohort followed longitudinally. Path analyses were used to model relationships between developmental vulnerabilities at age ~5 years, educational underachievement from ages ~8 to 10 years and three distinct profiles of schizotypy at age ~11 years (true, introverted and affective schizotypy). RESULTS: Early childhood developmental vulnerabilities on five broad domains (related to physical, emotional, social, cognitive and communication development) were associated with schizotypy profiles in middle childhood. Educational underachievement in middle childhood was associated with all schizotypy profiles, but most strongly with the true schizotypy profile (OR = 3.92, 95% CI = 3.12, 4.91). The relationships between schizotypy profiles and early childhood developmental vulnerabilities in 'language and cognitive skills (school-based)' and 'communication skills and general knowledge' domains were fully mediated by educational underachievement in middle childhood, and the relationships with early childhood 'physical health and well-being' and 'emotional maturity' domains were partially mediated. CONCLUSION: Developmental continuity from early childhood developmental vulnerabilities to schizotypy in middle childhood is mediated by educational underachievement in middle childhood. While some domains of early developmental functioning showed differential relationships with distinct schizotypy profiles, these findings support a developmental pathway to schizotypy in which cognitive vulnerability operates from early childhood through to middle childhood.

OBJECTIVE: The processes facilitating resilience are likely to be influenced by individual, familial and contextual factors that are dynamic across the life-course. These factors have been less studied in relation to resilience profiles evident in the developmental period between early to middle childhood, relative to later periods of adolescence or adulthood. METHOD: This study examined factors associated with resilience in a cohort of 4,716 children known to child protection services by age 13 years, in the Australian State of New South Wales. Latent profile and transition analyses were used to identify multi-dimensional profiles of resilience as evident in social, emotional and cognitive functioning when assessed in early childhood (time 1 [T1], age 5-6 years) and middle childhood (time 2 [T2], age 10-11 years). Logistic regression models were used to investigate factors associated with two types of resilience identified: a transition profile of stress-resistance (i.e., represented by a typically developing profile at both T1 and T2) delineated in the largest subgroup (54%) of children, and a smaller subgroup (13%) with a profile of emergent resilience (i.e., typically developing at T2 following a vulnerable profile at T1). RESULTS: Factors associated with resilience profiles included being female, and personality characteristics of openness and extraversion; other factors associated with stress-resistance, specifically, included higher socioeconomic status, non-Indigenous background, higher perceived port at home and at school, and not having a parent with a history of criminal offending. CONCLUSIONS: Resilience processes appear to involve a complex interplay between individual, family, and community characteristics requiring interagency support.

Maltreated children are vulnerable to adverse mental health outcomes. Information about how children's mental health needs vary according to different levels of child protection contact (potentially culminating in out-of-home care [OOHC]) is valuable for the effective provision of services. This study aimed to examine associations between different levels of contact with child protection services before the age of 10 years and self-reported mental health difficulties at age 11 years. Participants (n = 26,960) were drawn from the New South Wales Child Development Study, a multiagency, multigenerational, longitudinal record linkage study that combines administrative records with cross-sectional survey data. We examined associations between four levels of child protection response (non-threshold reports, unsubstantiated reports, substantiated reports, OOHC; each relative to no report) and six domains of self-reported mental health difficulties (including internalising and externalising symptoms, and psychotic-like experiences). All levels of contact with child protection services were associated with increased odds of mental health difficulties in all domains. Children who had been placed in OOHC and children with substantiated reports had the highest odds of reporting clinical levels of mental health difficulties; 48.1% of children with an OOHC placement and 45.6% of those with substantiated child protection reports showed clinical levels of mental health difficulties in at least one domain. Children with child protection reports that were unsubstantiated, or determined not to meet the threshold for risk-of-significant harm, were also at increased risk of mental health difficulties in middle childhood. These findings underscore the importance of early detection and intervention for all children at risk of maltreatment.

Distinct classes of children in the general population are at increased odds of later mental illness and other adverse outcomes according to patterns of early childhood developmental vulnerability. If certain risk factors known at the time of birth are reliably associated with membership in early childhood risk classes, then preventative interventions could be initiated in the earliest years of life. Associations between 14 factors known at the time of birth and membership in early childhood risk classes were examined in 66,464 children. Risk class membership was associated with maternal mental illness, parental criminal charges and being male; distinct patterns of association were shown for some conditions, for example, prenatal child protection notification was uniquely associated with misconduct risk'. These findings suggest that risk factors known at the time of birth could assist in very early detection of children who may benefit from early intervention in the first 2000 days.
RESUMO
BACKGROUND: Parental offending and mental illness are associated with an increased risk of criminal behaviour in offspring during adolescence and adulthood, but the impact of such problems on younger children, including children's experiences of victimisation, is less well known. AIM: To investigate the associations between parental offending and mental illness recorded prior to their offspring's age of 5 years and their offspring's contact with police as a 'person of interest', 'victim' or 'witness' between ages 5 and 13 years. METHODS: Our sample consisted of 72,771 children and their parents drawn from the New South Wales Child Development Study, an Australian longitudinal population-based record linkage study. Logistic regression analyses were conducted to examine associations between parental factors and offspring's police contact. Separate models examined the relationships between maternal or paternal offending and mental illness, as well as the combination among either or both parents, as the independent variables, and their child's police contact as the dependent variable. RESULTS: Parental offending and mental illness were each individually associated with indices of police contact among offspring. Stronger associations were observed when both offending and mental illness were present together (in either parent, or when one parent had both exposures). Stronger associations were evident for mothers with both factors across all offspring police contact types, relative to fathers with both factors, in fully adjusted models; that is, children of mothers with both factors were over four times as likely to have contact with police as a 'person of interest' (OR = 4.29; 95% CI = 3.75-4.92) and over three times as likely to have contact as a victim (OR = 3.35; 95% CI = 3.01-3.74) or witness (OR = 3.58; 95% CI = 3.03-4.24), than children whose mothers had no history of offending or mental illness. CONCLUSIONS: Children with a parental history of offending and mental illness in early life are at an increased likelihood of early police contact as young as 5-13 years of age; it is vital that this is taken as a signal to help them and their affected families according to need.

OBJECTIVES: The detection of young people at high risk for psychotic disorders has been somewhat narrowly focused on overt symptom-based markers that reflect mild reality distortion (e.g., psychotic-like experiences), or prodromal syndromes that are proximal to psychosis onset. The concept of schizotypy represents a broader framework for investigating risk for schizophrenia (and other disorders) in childhood, before the onset of prodromal or overt symptoms. We sought to detect profiles of risk for psychosis (schizotypy) in a general population sample of 22,137 Australian children aged 11-12 years, and to determine early life risk factors associated with these profiles from data available in linked records (registers). METHODS: Fifty-nine self-reported items were used as indicators of schizotypy across six broad domains; z-scores for each domain were subjected to latent profile analyses (LPA). A series of multinomial logistic regressions was used to examine the association between resulting profile (class) membership and several childhood and parental risk factors, and the proportion of children with mental disorders among each schizotypy profile was examined. RESULTS: The LPA revealed three person-centred profiles referred to as True Schizotypy (n = 1,323; 6.0%), Introverted Schizotypy (n = 4,473; 20.2%), and Affective Schizotypy (n = 4,261; 19.2%), as well as a group of children showing no risk (n = 12,080; 54.6%). Prior exposure to perinatal and familial adversities including childhood maltreatment, as well as poor early childhood development and academic functioning, was variously associated with all risk groups. There was a higher proportion of childhood mental disorder diagnoses among children in the True Schizotypy group, relative to other profiles. CONCLUSION: Subtle differences in the pattern of exposures and antecedents among schizophrenia liability profiles in childhood may reflect distinct pathogenic pathways to psychotic or other mental illness. PRACTITIONER POINTS: Children aged 11-12 years report characteristics of schizotypy which can be classified into three distinct profiles that may represent different pathological processes towards later mental ill-health. Early life exposure to perinatal and familial adversities including childhood maltreatment, early childhood developmental vulnerability, and poor academic functioning predict membership in all three childhood schizotypy profiles. Latent liability for schizophrenia (and potentially other mental disorders) may be represented by different profiles of functioning observable in childhood.

OBJECTIVES: Childhood psychotic-like experiences (PLEs) increase risk for concurrent and future psychiatric disorders but are common in the population. Strategies are needed to identify vulnerable individuals who may benefit from monitoring or targeted intervention. This study aimed to delineate profiles of childhood PLEs that might be differentially associated with other psychopathologies, and multiple psychopathology. DESIGN: Cross-sectional, online self-report survey. METHODS: Participants were 27,000 Australian children from a population cohort (13,416 girls; mean age 11.91 years) who completed an online self-report questionnaire assessing PLEs (hallucinations and delusions) and Emotional, Peer Relationship, Conduct, and Hyperactivity-Inattention psychopathology. Latent class analysis differentiated classes of children showing different patterns of PLE responses, and multinomial logistic regression determined the association between the PLE classes and the various psychopathologies, adjusted for demographic covariates and the other psychopathologies. RESULTS: Five latent profiles of PLE responses were characterized as follows: None (27.4% of children), Minor (29.7%), Moderate (11.8%), Hallucinatory (21.0%), and Strong (10.2%). These classes showed distinct associations with other psychopathologies (odds ratios between 1.27 and 4.58), and dose-response relationships indicated increasing likelihood of multiple psychopathology for the Hallucinatory and Strong classes (odds ratio = 21.87 for ≥3 psychopathologies in the Strong class). CONCLUSIONS: Tailored interventions that address the particular needs of these different classes of individuals may be warranted. PRACTITIONER POINTS: Children aged 11-12 years who report psychotic-like experiences (PLEs) can be classified into five different PLE profiles based on self-reported questionnaire responses, which may reflect different pathological processes. These PLE profiles show different patterns and magnitudes of increased risk for other types of psychopathology, and multiple psychopathology, suggesting that they present different treatment needs. Cross-sectional investigation of the associations between PLE profiles and other psychopathologies limits any conclusions as to the causal direction of these relationships. Multi-informant reports of psychopathology were unavailable.

Adult psychosocial difficulties, including psychiatric disorders, are often preceded by childhood psychosocial vulnerabilities, presenting critical windows of opportunity for preventative intervention. The present study aimed to identify longitudinal patterns (representing transitions between profiles) of childhood socio-emotional and cognitive vulnerability in the general population from early to middle childhood, in relation to key risk factors (e.g. parental mental illness and offending). Data were drawn from the New South Wales Child Development Study, which combines intergenerational multi-agency administrative records with cross-sectional assessments using data linkage methods. We analysed data from childhood assessments of socio-emotional and cognitive functioning at two time points (ages 5-6 and 10-11 years) that were linked with administrative data from government departments of health, child protection, and education for 19,087 children and their parents. Latent profile analyses were used to identify socio-emotional and cognitive profiles at each time point, and latent transition analyses were used to determine the probability and potential moderators of transition between profiles at each age. Three developmental profiles were identified in early childhood, reflecting typically developing, emotionally vulnerable, and cognitively vulnerable children, respectively; two profiles were identified in middle childhood, reflecting typically developing and vulnerable children. Child's sex, child protection services contact, parental mental illness, and parental offending influenced children's transitions between different vulnerability profiles, with the strongest effects for parental mental illness and child protection contact. Early detection of vulnerable children and factors promoting resilience are important steps in directing future health and social policy, and service planning for vulnerable children.

OBJECTIVE: This study examined associations between chronic physical health conditions (identified from hospital records) that are subject to school health care plans, and children's emotional, behavioral, and social functioning during early (â¼5 years of age) and middle childhood (â¼11 years). METHODS: Participants were 21,304 Australian children from a representative longitudinal population cohort derived by multi-agency record linkage. Hospital presentations (admitted patients and emergency department) identified children with asthma (n = 1,573), allergies and anaphylaxis (n = 738), type 1 diabetes (n = 59), epilepsy (n = 87), and any of these conditions (n = 2,275), relative to 19,029 children without these presentations. Logistic regression analyses determined associations between these exposures and (i) emotional, behavioral, social, and overall vulnerabilities reported by teachers (early childhood) and children (middle childhood), and (ii) self-reported lack of sources of support (middle childhood). RESULTS: Prevalence of any condition in hospital records was 7.5% by early childhood, and 10.7% by middle childhood. Relative to peers without these presentations, small increases in risk of overall problems, and selected emotional, behavioral, and social problems, were apparent for children with any condition, and asthma specifically, in early and middle childhood. Large and pervasive effects were apparent for epilepsy, limited small effects in middle childhood only for allergies and anaphylaxis, and no increases in risk associated with type 1 diabetes examined in middle childhood. No condition was associated with increased risk of lacking supports. CONCLUSIONS: Children with hospital records of chronic conditions, particularly epilepsy and asthma, might benefit from school-based care plans that integrate their physical and mental health support needs.

OBJECTIVE: We examined associations between developmental vulnerability profiles determined at the age of 5 years and subsequent childhood mental illness between ages 6 and 13 years in an Australian population cohort. METHODS: Intergenerational records from New South Wales (NSW) Government Departments of Health and Child Protection spanning pre-birth to 13 years of age were linked with the 2009 Australian Early Development Census records for 86,668 children. Mental illness indices for children were extracted from health records between 2009 and 2016 (child's age of 6-13 years). Associations between mental disorder diagnoses and membership of early childhood risk groups, including those with established 'special needs' (3777, 4.3%) at school entry, or putative risk classes delineated via latent class analysis of Australian Early Development Census subdomains - referred to as 'pervasive risk' ( N = 3479; 4.0%), 'misconduct risk' ( N = 5773; 6.7%) or 'mild generalised risk' ( N = 9542; 11%) - were estimated using multinomial logistic regression, relative to children showing 'no risk' ( N = 64,097; 74%). Poisson regression models estimated the relative risk of a greater number of days recorded with mental health service contacts among children in each Australian Early Development Census risk group. Adjusted models included child's sex, socioeconomic disadvantage, child protection contacts and parental mental illness as covariates. RESULTS: The crude odds of any mental disorder among children aged 6-13 years was increased approximately threefold in children showing pervasive risk or misconduct risk profiles at the age of 5 years, and approximately sevenfold in children with special needs, relative to children showing no risk; patterns of association largely remained after adjusting for covariates. Children with special needs and the misconduct risk class used mental health services over a greater number of days than the no risk class. CONCLUSION: Patterns of early childhood developmental vulnerability are associated with subsequent onset of mental disorders and have the potential to inform interventions to mitigate the risk for mental disorders in later childhood and adolescence.

PURPOSE: Although parental criminal offending is a recognized risk factor for conduct problems among offspring, its impact on the continuity and discontinuity of children's behavioural and emotional difficulties during the early development is less well known. We used data from a large, population-based record-linkage project to examine the relationship between parental offending and the continuity and discontinuity of children's conduct, attentional, and emotional difficulties from early to middle childhood while also considering the role of timing of the parental offending exposure. METHOD: Data for 19,208 children and their parents were drawn from the New South Wales Child Development Study. Multinomial regression analyses tested associations between mother's and father's history and timing of any and violent offending, and patterns of continuity or discontinuity in offspring emotional, conduct, and attentional difficulties between ages 5 and 11 years. RESULTS: Maternal and paternal offending each conferred a significantly increased risk of all the patterns of developmental difficulties, including those limited to age 5 only (remitting problems), to age 11 only (incident problems), and to difficulties present at both ages 5 and 11 years (persisting problems). Greatest odds were observed for persisting conduct problems. Paternal offending that continued through early and middle childhood had the greatest association with child difficulties, while the timing of maternal offending had a less prominent effect on child developmental difficulties. CONCLUSION: Parental offending is a strong risk factor for early and pervasive behavioural and emotional problems in offspring, and may be a key indicator of high risk for later antisocial behaviour.

BACKGROUND: The intergenerational risk for mental illness is well established within diagnostic categories, but the risk is unlikely to respect diagnostic boundaries and may be reflected more broadly in early life vulnerabilities. We aimed to establish patterns of association between externalising and internalising vulnerabilities in early childhood and parental mental disorder across the full spectrum of diagnoses. METHODS: A cohort of Australian children (n = 69 116) entering the first year of school in 2009 were assessed using the Australian Early Development Census, providing measures of externalising and internalising vulnerability. Parental psychiatric diagnostic status was determined utilising record-linkage to administrative health datasets. RESULTS: Parental mental illness, across diagnostic categories, was associated with all child externalising and internalising domains of vulnerability. There was little evidence to support interaction by parental or offspring sex. CONCLUSIONS: These findings have important implications for informing early identification and intervention strategies in high-risk offspring and for research into the causes of mental illness. There may be benefits to focusing less on diagnostic categories in both cases.

BACKGROUND: Fetal exposure to infectious and noninfectious diseases may influence early childhood developmental functioning, on the path to later mental illness. Here, we investigated the effects of in utero exposure to maternal infection and noninfectious diseases during pregnancy on offspring developmental vulnerabilities at age 5 years, in the context of estimated effects for early childhood exposures to infectious and noninfectious diseases and maternal mental illness. METHODS: We used population data for 66,045 children from an intergenerational record linkage study (the New South Wales Child Development Study), for whom a cross-sectional assessment of five developmental competencies (physical, social, emotional, cognitive, and communication) was obtained at school entry, using the Australian Early Development Census (AEDC). Child and maternal exposures to infectious or noninfectious diseases were determined from the NSW Ministry of Health Admitted Patients Data Collection (APDC) and maternal mental illness exposure was derived from both APDC and Mental Health Ambulatory Data collections. Multinomial logistic regression analyses were used to examine unadjusted and adjusted associations between these physical and mental health exposures and child developmental vulnerabilities at age 5 years. RESULTS: Among the physical disease exposures, maternal infectious diseases during pregnancy and early childhood infection conferred the largest associations with developmental vulnerabilities at age 5 years; maternal noninfectious illness during pregnancy also retained small but significant associations with developmental vulnerabilities even when adjusted for other physical and mental illness exposures and covariates known to be associated with early childhood development (e.g., child's sex, socioeconomic disadvantage, young maternal age, prenatal smoking). Among all exposures examined, maternal mental illness first diagnosed prior to childbirth conferred the greatest odds of developmental vulnerability at age 5 years. CONCLUSIONS: Prenatal exposure to infectious or noninfectious diseases appear to influence early childhood physical, social, emotional and cognitive developmental vulnerabilities that may represent intermediate phenotypes for subsequent mental disorders.

This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (Mage = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001-2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children.

OBJECTIVE: Detecting the early emergence of childhood risk for adult mental disorders may lead to interventions for reducing subsequent burden of these disorders. We set out to determine classes of children who may be at risk for later mental disorder on the basis of early patterns of development in a population cohort, and associated exposures gleaned from linked administrative records obtained within the New South Wales Child Development Study. METHODS: Intergenerational records from government departments of health, education, justice and child protection were linked with the Australian Early Development Census for a state population cohort of 67,353 children approximately 5 years of age. We used binary data from 16 subdomains of the Australian Early Development Census to determine classes of children with shared patterns of Australian Early Development Census-defined vulnerability using latent class analysis. Covariates, which included demographic features (sex, socioeconomic status) and exposure to child maltreatment, parental mental illness, parental criminal offending and perinatal adversities (i.e. birth complications, smoking during pregnancy, low birth weight), were examined hierarchically within latent class analysis models. RESULTS: Four classes were identified, reflecting putative risk states for mental disorders: (1) disrespectful and aggressive/hyperactive behaviour, labelled 'misconduct risk' ( N = 4368; 6.5%); (2) 'pervasive risk' ( N = 2668; 4.0%); (3) 'mild generalised risk' ( N = 7822; 11.6%); and (4) 'no risk' ( N = 52,495; 77.9%). The odds of membership in putative risk groups (relative to the no risk group) were greater among children from backgrounds of child maltreatment, parental history of mental illness, parental history of criminal offending, socioeconomic disadvantage and perinatal adversities, with distinguishable patterns of association for some covariates. CONCLUSION: Patterns of early childhood developmental vulnerabilities may provide useful indicators for particular mental disorder outcomes in later life, although their predictive utility in this respect remains to be established in longitudinal follow-up of the cohort.
