Latent profiles of early developmental vulnerabilities in a New South Wales child population at age 5 years

Information sharing between the dental healthcare and child welfare services regarding child maltreatment-A repeated cross-sectional study in Norway

BACKGROUND

Little is known about dental healthcare workers reported suspected child maltreatment to and received inquiry from the child welfare services (CWS).

AIM

Assess time lag differences in public dental healthcare workers' information sharing with CWS and identify sociodemographic and attitudinal covariates of information sharing with CWS in 2014 and 2019.

DESIGN

In 2014 and 2019, a national census of 1542 and 1791 Norwegian dental health care workers, respectively, were invited to participate in an electronic survey. Of them, 1200 (77.8%) and 1270 (70.9%) replied to the questionnaires. Time trends of reported child maltreatment and received inquiries were estimated and adjusted for sociodemographics, attitudes, trust, and collaborative routines in logistic regression analyses.

RESULTS

The likelihood of reported child maltreatment to and received inquiry from CWS was higher in 2019 than in 2014 (OR 1.4 [95% CI 1.2-1.7] and OR 1.1 [95% CI 0.9-1.4]). Significant associations occurred with sociodemographic characteristics, attitudes, and collaborative routines. The likelihood of receiving inquiry about whether being employed long versus short term was higher in 2019 than in 2014.

CONCLUSION

Information sharing between dental healthcare workers and CWS improved across time and might promote beneficial outcomes.

Conditions of Birth and Early Childhood Developmental Risk for Mental Disorders

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.

Leveraging Administrative Data to Better Understand and Address Child Maltreatment: A Scoping Review of Data Linkage Studies

BACKGROUND

This scoping review aimed to overview studies that used administrative data linkage in the context of child maltreatment to improve our understanding of the value that data linkage may confer for policy, practice, and research.

METHODS

We searched MEDLINE, Embase, PsycINFO, CINAHL, and ERIC electronic databases in June 2019 and May 2020 for studies that linked two or more datasets (at least one of which was administrative in nature) to study child maltreatment. We report findings with numerical and narrative summary.

RESULTS

We included 121 studies, mainly from the United States or Australia and published in the past decade. Data came primarily from social services and health sectors, and linkage processes and data quality were often not described in sufficient detail to align with current reporting guidelines. Most studies were descriptive in nature and research questions addressed fell under eight themes: descriptive epidemiology, risk factors, outcomes, intergenerational transmission, predictive modelling, intervention/service evaluation, multi-sector involvement, and methodological considerations/advancements.

CONCLUSIONS

Included studies demonstrated the wide variety of ways in which data linkage can contribute to the public health response to child maltreatment. However, how research using linked data can be translated into effective service development and monitoring, or targeting of interventions, is underexplored in terms of privacy protection, ethics and governance, data quality, and evidence of effectiveness.

A mixed-methods evaluation of a state-wide outreach perinatal mental health service

BACKGROUND

Access to perinatal mental health services in rural and remote areas is scarce, particularly perinatal psychiatry services. Telehealth, together with psychiatry consultation-liaison services are one way to improve access to areas of need. The New South Wales State-wide Outreach Perinatal Services - Mental Health (SwOPS) program is a Sydney-based program, offering specialist perinatal consultation-liaison services to rural and remote community mental health clinicians caring for perinatal women with significant mental health problems. This study aimed to evaluate healthcare practitioners' perceptions of the SwOPS program.

METHOD

Healthcare practitioners (N = 31) were purposely recruited to participate in the study. Data were analysed using a mixed-methods cross-sectional design.

RESULTS

Most participants reported being familiar with and satisfied with the service. As a result of accessing the service, participants reported an increase in knowledge and confidence regarding caring for women with moderate-to-severe or complex mental health conditions. Qualitative comments highlight the participant's perceptions of the program.

CONCLUSION

This study provides useful insights about a state-wide telehealth psychiatry consultation-liaison service from the perspective of practitioners. It highlights the benefits, facilitators, and barriers associated with implementing such services.

Risk factors for developmental vulnerability: Insight from population-level surveillance using the Early Development Instrument

Objectives

Population-level studies may elucidate the most promising intervention targets to prevent negative outcomes of developmental vulnerability in children. This study aims to bridge the current literature gap on identifying population-level developmental vulnerability risk factors using combined social and biological/health information.

Methods

This study assessed developmental vulnerability among kindergarten children using the 2016 Early Development Instrument (EDI) and identified risk factors of developmental vulnerability using EDI data cross-linked to a population-wide administrative health dataset. A total number of 23,494 children aged 5-6 were included (48% female). Prenatal, neonatal, and early childhood risk factors for developmental vulnerability were investigated, highlighting the most important ones contributing to early development.

Results

The main risk factors for developmental vulnerability were children with a history of mental health diagnosis (risk ratio  = 1.46), biological sex-male (risk ratio =  1.51), and poor socioeconomic status (risk ratio =  1.58).

Conclusion

Our study encompasses both social and health information in a populational-level representative sample of Alberta, Canada. The results confirm evidence established in other geographic regions and jurisdictions and demonstrate the association between perinatal risk factors and developmental vulnerability. Based on these results, we argue that the health system should adopt a multilevel prevention and intervention strategy, targeting individual, family, and community together.

Regional mapping of early childhood risk for mental disorders in an Australian population sample

AIM

Population-level profiles of risk for later childhood mental disorders have been identified in patterns of early developmental vulnerabilities using Australian Early Developmental Census. We sought to demonstrate the geographical distribution of these early childhood risk profiles for mental illness, to inform policy decisions for place-sensitive provision of health and allied services.

METHODS

Using geographic information system techniques, we mapped the regional percentage of children at highest risk for mental disorders across the state of New South Wales (NSW), according to Local Government Areas, for 82 891 children in the NSW Child Development Study.

RESULTS

A high proportion (>10%) of children at risk of later mental disorders were located in regional and socioeconomically disadvantaged areas, with a few metropolitan regions showing similarly high proportions of the population at risk.

CONCLUSIONS

These findings highlight the potential to identify place-sensitive needs for early intervention and prevention programs for emerging mental health problems in children.

School Readiness of Children Exposed to Family and Domestic Violence

Children have a universal right to live free from exposure to family and domestic violence (FDV). Children exposed to FDV can experience long-term effects on their physical and psychological health and their social competencies including social, emotional, and cognitive skills and behaviours that underpin successful social adaptation and academic achievement. The aim of this study was to investigate if children exposed to FDV were more likely to be vulnerable on school readiness measures compared to those children who were not exposed. Our cohort study used de-identified individual-level administrative data of children born during 2002-2010, in Western Australia, who were identified in police and hospital records as being exposed to FDV during 2002-2015. Univariate and multivariate logistic regression was used to estimate the odds of vulnerability in Australian Early Development Census (AEDC) outcomes of children exposed to FDV compared to a non-exposed cohort. After adjusting for demographic characteristics, children exposed to FDV had higher odds than non-exposed children of being vulnerable in all five AEDC domains: physical health and wellbeing, social competence, emotional maturity, language and cognitive skills (school-based) and communication skills and general knowledge. Exposed children have an increased likelihood of vulnerability in all five AEDC domains: physical health and wellbeing, social competence, emotional maturity, language and cognitive skills (school-based) and communication skills and general knowledge. Comprehensive multiagency early intervention for children exposed to FDV is required to mitigate the impact on outcomes, and ultimately the need to prevent FDV is needed.

Early childhood developmental vulnerability associated with parental mental disorder comorbidity

OBJECTIVES

Parental mental health has a profound influence on the mental health and well-being of their offspring. With comorbid mental disorders generally the rule rather than the exception, increased knowledge of the impact of parental mental disorder comorbidity on early child development may facilitate improved targeting and delivery of early intervention for vulnerable offspring.

METHODS

Participants were 66,154 children and their parents in the New South Wales Child Development Study - a prospective, longitudinal, record-linkage study of a population cohort of children born in NSW between 2002 and 2004. Early childhood developmental vulnerability was assessed at age ~5 years using the Australian Early Development Census, and information on parental mental disorders was obtained from administrative health records. Binomial and multinomial logistic regression were used to assess the relationship between parental mental disorders and early childhood developmental vulnerability on emotional and behavioural domains, as well as membership of latent developmental risk classes reflecting particular classes of vulnerability.

RESULTS

Multiple diagnoses of mental disorders in mothers and fathers were associated with an increased likelihood of early childhood emotional and behavioural developmental vulnerability in offspring, relative to parents without mental disorder. The likelihood of offspring vulnerability increased with the number of parental comorbidities, particularly maternal comorbidities.

CONCLUSION

Early childhood developmental vulnerability was strongly associated with parental mental ill-health, with the strength of associations increasing in line with a greater number of mental disorder diagnoses among mothers and fathers. New and expectant parents diagnosed with multiple mental disorders should be prioritised for intervention, including attention to the developmental well-being of their offspring.

Familial clustering of birth risk for adverse childhood outcomes

OBJECTIVE

To identify classes of children exposed to distinct clusters of perinatal and familial risk factors at the time of birth, and examine relationships between class membership and a variety of adverse outcomes in childhood.

DESIGN

A prospective longitudinal study of children (and their parents) born between 2002 and 2004 and who have been followed-up until 12-13 years of age. A combination of latent class analysis and logistic regression analyses were used.

RESULTS

Adverse developmental, social, and mental health outcomes in early and middle childhood were greatest for children with 'pervasive familial risk' (i.e., parental mental illness, parental criminality, and perinatal risk factors) at the time of birth; some associations were stronger among girls.

CONCLUSION

Pervasive exposure to multiple risk factors in the pre- and perinatal period increases the risk of adverse outcomes in childhood. Future interventions should tailor strategies to address unique combinations of adverse risk exposures in vulnerable families.

Forecasting childhood adversities from conditions of birth

BACKGROUND

Childbirth presents an optimal time for identifying high-risk families to commence intervention that could avert various childhood health and social adversities.

OBJECTIVE

We sought to establish the minimum set of exposures required to accurately predict a range of adverse childhood outcomes up to the age of 13 years, from a set of 14 individual and familial risk exposures evident at the time of birth.

METHODS

Participants were 72,059 Australian children and their parents drawn from a multi-register population cohort study (data spanning 1994-2018). Risk exposures included male sex, young mother (aged ≤21 years), no (or late first; >16 weeks) antenatal visit, maternal smoking during pregnancy, small for gestational age, preterm birth, pregnancy complications (any of hypertension, diabetes mellitus, gestational diabetes or pre-eclampsia), >2 previous pregnancies of ≥20 weeks, socio-economic disadvantage, prenatal child protection notification, and maternal or paternal mental disorder or criminal offending history. Individual outcomes included early childhood developmental vulnerability (age 5 years), sustained educational underachievement (age 8 and 10 years), mental disorder diagnoses, substantiated childhood maltreatment, and contact with the police as a victim or person-of-interest up to age 13-14 years.

RESULTS

Risk exposures at birth predicted individual childhood outcomes with fair to excellent accuracy: the area under the receiver operating characteristic curves ranged between 0.60 (95% CI 0.58, 0.62) for childhood mental disorder and 0.83 (95% CI 0.82, 0.85) for substantiated child maltreatment. The presence of five or more exposures characterised 12-25% of children with one or more adverse outcomes and showed high predictive certainty for models predicting multiple outcomes, which were apparent in 9% of the population.

CONCLUSIONS

Up to a quarter of the neonatal population at risk of multiple adverse outcomes can be detected at birth, with implications for population health screening. However, cautious implementation of these models is warranted, given their relatively low positive predictive values.

Pathways to school success: Self-regulation and executive function, preschool attendance and early academic achievement of Aboriginal and non-Aboriginal children in Australia's Northern Territory

Background

With the pending implementation of the Closing the Gap 2020 recommendations, there is an urgent need to better understand the contributing factors of, and pathways to positive educational outcomes for both Aboriginal and non-Aboriginal children. This deeper understanding is particularly important in the Northern Territory (NT) of Australia, in which the majority of Aboriginal children lived in remote communities and have language backgrounds other than English (i.e. 75%).

Methods

This study linked the Australian Early Development Census (AEDC) to the attendance data (i.e. government preschool and primary schools) and Year 3 National Assessment Program for Literacy and Numeracy (NAPLAN). Structural equation modelling was used to investigate the pathway from self-regulation and executive function (SR-EF) at age 5 to early academic achievement (i.e. Year 3 reading/numeracy at age 8) for 3,199 NT children.

Result

The study confirms the expected importance of SR-EF for all children but suggests the different pathways for Aboriginal and non-Aboriginal children. For non-Aboriginal children, there was a significant indirect effect of SR-EF (β = 0.38, p<0.001) on early academic achievement, mediated by early literacy/numeracy skills (at age 5). For Aboriginal children, there were significant indirect effects of SR-EF (β = 0.19, p<0.001) and preschool attendance (β = 0.20, p<0.001), mediated by early literacy/numeracy skills and early primary school attendance (i.e. Transition Years to Year 2 (age 5–7)).

Conclusion

This study highlights the need for further investigation and development of culturally, linguistically and contextually responsive programs and policies to support SR-EF skills in the current Australian education context. There is a pressing need to better understand how current policies and programs enhance children and their families’ sense of safety and support to nurture these skills. This study also confirms the critical importance of school attendance for improved educational outcomes of Aboriginal children. However, the factors contributing to non-attendance are complex, hence the solutions require multi-sectoral collaboration in place-based design for effective implementation.

Incidence of Early Police Contact Among Children With Emerging Mental Health Problems in Australia

IMPORTANCE

In adulthood and adolescence, mental health vulnerability is known to be associated with risk of criminal justice system contact as both a perpetrator and survivor of crime, but whether this association is apparent early in child development is unknown. Prevention of poor outcomes, including repeated contact with the criminal justice system, relies on the identification of vulnerability early in life and at the start of such contact.

OBJECTIVE

To ascertain whether children with emotional or behavioral problems and general developmental vulnerabilities are at an increased risk of subsequent contact with police as a person of interest, a survivor of crime, or a witness.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study used routinely collected data from the New South Wales Child Development Study in Australia. The cohort was composed of children who entered full-time schooling in New South Wales in 2009, had complete data for the emotional maturity domain of the Australian Early Development Census, and had no police contact before January 1, 2009. The children in the cohort were followed up until the age of 13 years. Data were analyzed from October 17, 2019, to May 13, 2020.

EXPOSURES

Emotional or behavioral problems and developmental risk profiles derived from the teacher-rated Australian Early Development Census.

MAIN OUTCOMES AND MEASURES

Incidence rates of police contact (as a person of interest, survivor of crime, or witness) were derived from the New South Wales Police Force Computerised Operational Policing System.

RESULTS

A total of 79 801 children (40 584 boys [50.9%]; 2009 mean [SD] age, 5.2 [0.37] years) were included. Children with teacher-identified emotional or behavioral problems at school entry had an incidence rate of police contact (for any reason) that was twice that of children without such problems (unadjusted hazard ratio [HR], 2.14; 95% CI, 1.94-2.37). Contact with police as a survivor of crime was most commonly recorded (7350 [9.2%]), but the strength of the association was greatest between emotional or behavioral problems and police contact as a person of interest (unadjusted HR, 4.75; 95% CI, 3.64-6.19). Incidence of police contact as a person of interest was high for children with a pervasive developmental risk profile (unadjusted HR, 13.80; 95% CI, 9.79-19.45).

CONCLUSIONS AND RELEVANCE

This study found an association of emerging emotional or behavioral problems and developmental vulnerabilities with increased risk of police contact for any reason among young children, suggesting that this well-known association in adults and adolescents can be identified at an earlier developmental stage. These findings support primary and secondary interventions to prevent police contact early in life and to target the earliest contacts with the criminal justice and educational systems.

Population-Level Data on Child Development at School Entry Reflecting Social Determinants of Health: A Narrative Review of Studies Using the Early Development Instrument

Background: The Early Development Instrument (EDI) was developed as a population-level assessment of children’s developmental health at school entry. EDI data collection has created unprecedented opportunities for population-level studies on children’s developmental outcomes. The goal of this narrative review was to synthesize research using the EDI to describe how it contributes to expanding the understanding of the impacts of social determinants on child development and how it applies to special populations. Methods: Select studies published in peer-reviewed scientific journals between 2015 and 2020 and incorporating the social determinants of health perspectives were chosen to highlight the capability of the EDI to monitor children’s developmental health and contribute knowledge in the area of early childhood development. Results: A number of studies have examined the association between several social determinants of health and children’s developmental outcomes, including hard-to-reach and low-frequency populations of children. The EDI has also been used to evaluate programs and interventions in different countries. Conclusions: The ability of the EDI to monitor children’s developmental outcomes in various populations has been consistently demonstrated. The EDI, by virtue of its comprehensive breadth and census-like collection, widens the scope of research relating to early childhood development and its social determinants of health.

Adverse childhood experiences-household stressors and children's mental health: a single centre retrospective review

OBJECTIVE

To determine the prevalence of reported 'household stressor' adverse childhood experiences (ACEs) in families of children presenting with neurodevelopmental, behavioural or emotional difficulties and to determine whether family vulnerabilities, individually or cumulatively, were associated with particular clinical symptomatology.

DESIGN

Retrospective chart review followed by statistical analysis of family stressors and clinical symptomatology.

SETTING

A community paediatric clinic in Australia.

PARTICIPANTS

All 267 children who attended an initial paediatric appointment during 2018.

RESULTS

162 (60.7%) children had been exposed to one or more household stressor ACEs, including 116 (43.4%) children exposed to parental mental illness. Behavioural disturbance occurred in 144 (53.9%) children and externalising behaviours (other than attention deficit hyperactivity disorder) were more frequent than internalising behaviours. Externalising and internalising behaviours were associated with individual and cumulative household stressor ACEs. Most other symptomatology apart from genetic/neurological conditions, autistic symptoms and some developmental delays appeared to be partially associated with ACEs.

CONCLUSION

Household stressor ACEs were common, frequently occurred concurrently, and were associated with much of the symptomatology, in this cohort. Parental mental illness was the most prevalent stressor and behavioural disturbance the most prevalent symptomatology. These findings may have implications for clinical practice and service provision.

Collaboration of Child Protective Services and Early Childhood Educators: Enhancing the Well-Being of Children in Need

This paper examines the role of interprofessional collaboration in the identification and reporting of a child in need. Such collaboration is especially important in the context of the global pandemic caused by the novel Coronavirus disease of 2019, known as COVID-19. The child protection system must have the capacity and resources to respond to increased demands during this time, and early childhood educators serve as an essential link for child protective services in identifying and reporting a child in need. As an effective system to accomplish these two aims requires a working collaboration among its participants, Bronstein's interdisciplinary collaboration model was used as a framework to interpret this practice. A small-scale qualitative study was conducted that included principals of nursery schools and child protection workers from one region in Estonia. Findings indicate that effective collaboration was believed to require communication and ongoing systematic relationship building. Collaboration in practice varied, as principals reported a high turnover rate for the child protection workers, which hindered the development of a working relationship and support for the process of noticing and thereby identifying a child in need. In contrast, child protection workers assessed collaboration more positively, recognizing the need to have a supportive system in place for nursery schools. Both groups of collaborators acknowledged the need to train teachers, particularly to conduct joint training exercises to foster a common understanding of the child in need and of the intervention process itself.

Transitions between socio-emotional and cognitive vulnerability profiles from early to middle childhood: a population study using multi-agency administrative records

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.

Antenatal interpersonal sensitivity as an early predictor of vulnerable mother-infant relationship quality

Maternal mental health problems in the perinatal period incur significant human and economic costs attributable to adverse child outcomes. In response, governments invest in screening for perinatal depressive symptoms. Mother-infant relationship quality (MIRQ) is a key mechanism linking maternal perinatal mental health to child outcomes. Perinatal depressive symptoms are typically transient while personality style, including interpersonal sensitivity, is a more stable construct. We have demonstrated that antenatal interpersonal sensitivity independently predicted MIRQ at 12 months postpartum. Building on our previous work, the objective of this study was to examine the associations of antenatal interpersonal sensitivity and depressive symptoms with MIRQ 1 year postnatal. A sample of 73 women attending routine antenatal care, 61 (84%) from ethnically diverse populations, were studied across the perinatal period. At ⩽26 weeks, gestation interpersonal sensitivity and depressive symptoms were measured. At 12 months, postnatal mental health and MIRQ was assessed in 35 of the mother-infant dyads. We found no significant statistical association between antenatal interpersonal sensitivity and depressive symptoms with postnatal MIRQ. Interpersonal sensitivity (r = -.24) showed weak association with MIRQ. Depressive symptom scores were not associated (r =-.01). Maternal sensitivity assessment (MIRQ) using the CARE-Index identified low mean scores signifying low levels of maternal sensitivity (potential range 0-14; mean score = 6.3). We cautiously suggest that the findings raise questions about the presentation and assessment of perinatal mental health status among ethnically diverse populations and scoping of parenting support needs within this population.

Associations between prenatal maternal mental health indices and mother-infant relationship quality 6 to 18 months' postpartum: A systematic review

Maternal mental disorders can significantly impact on children's psychosocial and psychological development, incurring substantial ongoing economic and personal costs. A key mediating mechanism is mother-infant relationship quality (MIRQ). Research studies and perinatal mental health screening initiatives have predominantly focused on depressive symptoms and perinatal depression as predictors of MIRQ. While maternal depression is associated with suboptimal MIRQ, the findings have not been consistent. Personality characteristics are associated with parenting and proneness to depression, presenting a potential addition to prenatal mental health assessment. We conducted a systematic review of studies that have examined the link between prenatal depressive symptoms and/or personality characteristics with postnatal MIRQ. Our findings suggest that both maternal personality traits and depressive symptoms measured in early pregnancy are associated with postnatal MIRQ. A measure of personality characteristics may enhance prenatal mental health assessment, affording opportunities for targeted intervention commencing in pregnancy to improve MIRQ, parenting, maternal mental health outcomes, and infant psychosocial and psychological development, and thereby contributing to the reduction of human and economic cost burdens.

Early developmental risk for subsequent childhood mental disorders in an Australian population cohort

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.
