Psychosocial assessment tools for children and young people aged 5-18 years: A rapid review of the literature.

AIM: Schools are a key platform for health promotion and a point of connection to local health-care services, with an almost universal reach across the child and adolescent population. This study sought to determine whether validated psychosocial assessment tools exist for a school-based nursing program that would assist in providing an initial health assessment to identify and understand the needs of children and young people referred to the nurse, with the outcome of appropriate connection to external health and wellbeing services. METHODS: Rapid evidence assessment methodology was utilised to identify validated tools that could identify psychosocial concerns in children and young people aged 5-18 years. We identified articles from peer-reviewed journals via three electronic bibliographic databases (PubMed, Embase and CINAHL). We then extended the search for evidence through a search of the grey literature. RESULTS: From 3963 peer-reviewed articles found in the database search, 10 relevant peer-reviewed publications met inclusion criteria. In combination with 12 grey literature sources, 33 tools were identified. These included self-report tools (typically for children aged 11 years and older), parent-report and teacher-report tools. We identified the six most promising psychosocial assessment tools. However, there was limited description about implementation within school-based nursing programs. CONCLUSIONS: Several tools exist that show promise in assisting school-based nursing programs to conduct preliminary psychosocial assessments for children and young people. The introduction of any tools into practice would require implementation guidance and evaluation, including how and when they should be used, and when referral and follow-up is required.

Prevalence and associated skills of Australian general practice registrars seeing children with functional bowel and bladder problems.

AIM: Functional bowel (constipation and faecal incontinence) and bladder (urinary incontinence and enuresis) problems in children are often treated by paediatricians yet should mostly be managed by general practitioners (GPs). To understand whether the necessary skills and knowledge are being built in general practice, this study aimed to establish the prevalence and associated skills of Australian general practice registrars managing children with functional bowel and bladder problems. Together as paediatricians and GPs, we use these data to determine how best to ensure high quality, equitable care for children. METHODS: We drew on 16 rounds of data collection from the Registrar Clinical Encounters in Training (ReCEnT) multi-site cohort study (2010-2017) of general practice registrars' in-consultation experience. It included a measure of paediatric consultations in which a functional bowel or bladder problem was managed, as well as demographic information. RESULTS: Out of 62 721 problems/diagnoses for paediatric patients (0-17 years), 844 (1.4%) were coded as functional bowel (n = 709; 1.13% (95% confidence interval, CI: 1.05-1.22)) and/or bladder (n = 135; 0.22% (95% CI: 0.18-0.25)) presentations. Registrars were more likely to prescribe medication for bowel problems (odds ratio (OR) = 2.22 (95% CI: 1.86-2.64)) than for all other problems, but less likely to prescribe medication (OR = 0.31 (95% CI: 0.18-0.52)) for night-time wetting and more likely to make a specialist referral (OR = 1.99 (95% CI: 1.22-3.25)) compared to all other problems. CONCLUSIONS: Only a small proportion of children with functional bowel and bladder problems were seen by registrars despite high prevalence in the community and amenability to management in the general practice setting (i.e. generally low morbidity and low complexity) versus need for specialists. Registrars appeared to be managing functional bowel and bladder problems according to evidence-based guidelines, but with relatively high levels of referral. Given the inequitable access to specialist care, paediatricians should support local general practice management of these problems. This might include (i) engaging with training programs to ensure appropriate education and (ii) liaising with individual registrars/practices to provide management advice for individual or example cases.

Potential indirect impacts of the COVID-19 pandemic on children: a narrative review using a community child health lens.

▪In this narrative review, we summarise the vast and burgeoning research on the potential and established indirect impacts on children of the COVID-19 pandemic. We used a community child health lens to organise our findings and to consider how Australia might best respond to the needs of children (aged 0-12 years). ▪We synthesised the literature on previous pandemics, epidemics and natural disasters, and the current COVID-19 pandemic. We found clear evidence of adverse impacts of the COVID-19 pandemic on children that either repeated or extended the findings from previous pandemics. ▪We identified 11 impact areas, under three broad categories: child-level factors (poorer mental health, poorer child health and development, poorer academic achievement); family-level factors that affect children (poorer parent mental health, reduced family income and job losses, increased household stress, increased abuse and neglect, poorer maternal and newborn health); and service-level factors that affect children (school closures, reduced access to health care, increased use of technology for learning, connection and health care). ▪There is increasing global concern about the likely disproportionate impact of the current pandemic on children experiencing adversity, widening existing disparities in child health and developmental outcomes. ▪We suggest five potential strategy areas that could begin to address these inequities: addressing financial instability through parent financial supplements; expanding the role of schools to address learning gaps and wellbeing; rethinking health care delivery to address reduced access; focusing on prevention and early intervention for mental health; and using digital solutions to address inequitable service delivery.

Oral health care: The experience of Australian paediatricians.

AIM: Many Australian children have dental decay in their deciduous teeth. Poor oral health can negatively impact a child's ability to eat, speak, sleep and socialise, with adverse impacts later in life. Paediatricians are well placed to examine children's teeth and to provide advice and education about oral health. Using a sample of Australian paediatricians, we aimed to determine: (i) self-reported oral health knowledge and skills, (ii) frequency of office-based oral health-related discussions, (iii) perceived role of paediatricians and (iv) barriers to oral health-related discussions. METHODS: Members of a national network of paediatricians - the Australian Paediatric Research Network - completed a multi-topic survey, which included questions designed to assess oral health knowledge, current practice and barriers to oral health-related discussions. RESULTS: Of 430 active members, 178 (41%) completed the survey. Few paediatricians reported very good/excellent ability to assess plaque build-up (8%) and dental caries (17%). Only 10% reported broaching the issue of oral health with all patients. Significant barriers included lack of professional training (52%) and other more pressing issues needing to be addressed (67%). CONCLUSIONS: The increasing (and inequitable) rates of dental decay in Australian children mean that paediatricians should play a key role in the management of children's oral health. Many paediatricians reported a lack of specific training in oral health and limited ability to assess children and educate families. Despite the traditional divide between medicine and oral health, this study highlights the opportunity for Australian paediatricians to improve oral health through early intervention in the consultation room and beyond.

Trends in the prevalence and distribution of teacher-identified special health-care needs across three successive population cohorts.

AIM: Some children's special health-care needs (SHCN) are formalised at the start of schooling (established SHCN), but a larger proportion start with difficulties that are milder or not yet diagnosed (emerging SHCN). This study explores whether: (i) the prevalence of teacher-identified SHCN (both overall and according to type of needs) and (ii) distribution across disadvantaged communities have changed over three successive population cohorts of Australian children. METHODS: We draw on repeated cross-sectional data from the Australian Early Development Census, a teacher-reported checklist completed on full populations of Australian school entrants in 2009, 2012 and 2015. It includes a measure of SHCN, as well as demographic information. RESULTS: The proportion of children with emerging and established needs was mostly stable from 2009 to 2015 (emerging needs: 17.1-18.9%; established needs: 4.4-4.9%). Change over time was observed in the prevalence of some specific types of impairment. Speech impairment rose by 14.7% for children with emerging needs, and emotional problems rose by 13.7% for children with established needs. Children living in the most disadvantaged neighbourhoods had higher odds of SHCN in all years (e.g. emerging needs relative risk ratio 1.65 (99% confidence interval 1.55-1.75) in 2015; established needs relative risk ratio 1.88 (99% confidence interval 1.71-2.06) in 2015). CONCLUSIONS: A large proportion of children starting school each year have SHCN. The types of SHCN that children present with increasingly reflect complex difficulties that require input from both the health and education sectors. Effective responses also need to consider the added impact of disadvantage.

Household income supplements in early childhood to reduce inequities in children's development.

BACKGROUND: Early childhood interventions have the potential to reduce children's developmental inequities. We aimed to estimate the extent to which household income supplements for lower-income families in early childhood could close the gap in children's developmental outcomes and parental mental health. METHODS: Data were drawn from a nationally representative birth cohort, the Longitudinal Study of Australian Children (N = 5107), which commenced in 2004 and conducted follow-ups every two years. Exposure was annual household income (0-1 year). Outcomes were children's developmental outcomes, specifically social-emotional, physical functioning, and learning (bottom 15% versus top 85%) at 4-5 years, and an intermediate outcome, parental mental health (poor versus good) at 2-3 years. We modelled hypothetical interventions that provided a fixed-income supplement to lower-income families with a child aged 0-1 year. Considering varying eligibility scenarios and amounts motivated by actual policies in the Australian context, we estimated the risk of poor outcomes for eligible families under no intervention and the hypothetical intervention using marginal structural models. The reduction in risk under intervention relative to no intervention was estimated. RESULTS: A single hypothetical supplement of AU$26,000 (equivalent to ∼USD$17,350) provided to lower-income families (below AU$56,137 (∼USD$37,915) per annum) in a child's first year of life demonstrated an absolute reduction of 2.7%, 1.9% and 2.6% in the risk of poor social-emotional, physical functioning and learning outcomes in children, respectively (equivalent to relative reductions of 12%, 10% and 11%, respectively). The absolute reduction in risk of poor mental health in eligible parents was 1.0%, equivalent to a relative reduction of 7%. Benefits were similar across other income thresholds used to assess eligibility (range, AU$73,329-$99,864). CONCLUSIONS: Household income supplements provided to lower-income families may benefit children's development and parental mental health. This intervention should be considered within a social-ecological approach by stacking complementary interventions to eliminate developmental inequities.

Addressing Child Mental Health Inequities Through Parental Mental Health and Preschool Attendance.

BACKGROUND: Prevention is key to reducing socioeconomic inequities in children's mental health problems, especially given limited availability and accessibility of services. We investigated the potential to reduce inequities for disadvantaged children by improving parental mental health and preschool attendance in early childhood. METHODS: Data from the nationally representative birth cohort, Longitudinal Study of Australian Children (N = 5107, commenced in 2004), were used to examine the impact of socioeconomic disadvantage (0-1 year) on children's mental health problems (10-11 years). Using an interventional effects approach, we estimated the extent to which inequities could be reduced by improving disadvantaged children's parental mental health (4-5 years) and their preschool attendance (4-5 years). RESULTS: Disadvantaged children had a higher prevalence of elevated mental health symptoms (32.8%) compared with their nondisadvantaged peers (18.7%): confounder-adjusted difference in prevalence is 11.6% (95% confidence interval: 7.7% to 15.4%). Improving disadvantaged children's parental mental health and their preschool attendance to the level of their nondisadvantaged peers could reduce 6.5% and 0.3% of socioeconomic differences in children's mental health problems, respectively (equivalent to 0.8% and 0.04% absolute reductions). If these interventions were delivered in combination, a 10.8% (95% confidence interval: 6.9% to 14.7%) higher prevalence of elevated symptoms would remain for disadvantaged children. CONCLUSIONS: Targeted policy interventions that improve parental mental health and preschool attendance for disadvantaged children are potential opportunities to reduce socioeconomic inequities in children's mental health problems. Such interventions should be considered within a broader, sustained, and multipronged approach that includes addressing socioeconomic disadvantage itself.

Why are some people with neurological illness more resilient than others?

The current qualitative study was designed to evaluate the coping strategies of people living with a chronic progressive neurological illness and their carers. The neurological illnesses were Huntington's disease, motor neurone disease, multiple sclerosis and Parkinson's disease. Participants included 15 people who showed high levels of adjustment and 15 who showed low levels of adjustment. Participants were selected from an earlier study, to ensure that they satisfied the inclusion criteria for the current study. Interviews were completed to determine the strategies used to cope with the demands of the illness. Participants who demonstrated good adjustment were more likely to draw on social support to provide them with the resources to deal with the illness. In contrast, those who evidenced poor adjustment were more likely to draw on external supports to complete tasks for them. The implications of these findings for people with chronic neurological illnesses and their families are discussed.

Comparative inequalities in child dental caries across four countries: Examination of international birth cohorts and implications for oral health policy.

Child dental caries (i.e., cavities) are a major preventable health problem in most high-income countries. The aim of this study was to compare the extent of inequalities in child dental caries across four high-income countries alongside their child oral health policies. Coordinated analyses of data were conducted across four prospective population-based birth cohorts (Australia, n = 4085, born 2004; Québec, Canada, n = 1253, born 1997; Rotterdam, the Netherlands, n = 6690, born 2002; Southeast Sweden, n = 7445, born 1997), which enabled a high degree of harmonization. Risk ratios (adjusted) and slope indexes of inequality were estimated to quantify social gradients in child dental caries according to maternal education and household income. Children in the least advantaged quintile for income were at greater risk of caries, compared to the most advantaged quintile: Australia: AdjRR = 1.18, 95%CI = 1.04-1.34; Québec: AdjRR = 1.69, 95%CI = 1.36-2.10; Rotterdam: AdjRR = 1.67, 95%CI = 1.36-2.04; Southeast Sweden: AdjRR = 1.37, 95%CI = 1.10-1.71). There was a higher risk of caries for children of mothers with the lowest level of education, compared to the highest: Australia: AdjRR = 1.18, 95%CI = 1.01-1.38; Southeast Sweden: AdjRR = 2.31, 95%CI = 1.81-2.96; Rotterdam: AdjRR = 1.98, 95%CI = 1.71-2.30; Québec: AdjRR = 1.16, 95%CI = 0.98-1.37. The extent of inequalities varied in line with jurisdictional policies for provision of child oral health services and preventive public health measures. Clear gradients of social inequalities in child dental caries are evident in high-income countries. Policy related mechanisms may contribute to the differences in the extent of these inequalities. Lesser gradients in settings with combinations of universal dental coverage and/or fluoridation suggest these provisions may ameliorate inequalities through additional benefits for socio-economically disadvantaged groups of children.

The impact of oral ED medication on female partners' relationship satisfaction.

INTRODUCTION: Research has demonstrated that erectile dysfunction (ED) is a couple's problem, and that treatment for this condition is likely to impact on the man and his partner. AIM: The current study utilized a qualitative approach to evaluate the impact of treatment for ED on the female partner's perception of changes in the relationship. MAIN OUTCOME MEASURES: Analyses of the transcripts from the interviews. METHODS: In total, 96 men were treated for ED using tadalafil and then sildenafil (or vice versa) each for 3 months. Their female partners were interviewed 3 months after the commencement of treatment. RESULTS: The findings demonstrated an overall positive effect of the treatment. Female partners perceived improvements in emotional closeness, and communication, and reported that their relationship was more loving, less stressful, and more stable. CONCLUSIONS: This study demonstrates the positive effects of treatment for ED on the female partner; in particular, on her perception of the quality of her relationship.

Predictors of quality of life in carers for people with a progressive neurological illness: a longitudinal study.

PURPOSE: The aim of the present research was to determine the predictors of quality of life (QOL) among carers for people living with a chronic degenerative neurological illness, with comparisons of the differences in significant predictors of QOL between illness groups. METHODS: Psychosocial and economic variables were examined among 192 carers for people living at home with motor neurone disease, Huntington's disease, multiple sclerosis, and Parkinson's, over a twelve-month period, to determine their contribution to the prediction of carer QOL. RESULTS: Mood was the only consistent predictor of carer QOL across groups; however, marital relationship satisfaction, social support satisfaction, income, and economic pressure significantly predicted carer QOL for at least one of the illness groups, in addition to mood. CONCLUSIONS: The findings highlight the importance of recognising the varying roles that psychosocial and economic variables play on the prediction of carer QOL within each of these illness groups.

Inequities in Children's Reading Skills: The Role of Home Reading and Preschool Attendance.

OBJECTIVE: Children from socioeconomically disadvantaged backgrounds have poorer learning outcomes. These inequities are a significant public health issue, tracking forward to adverse health outcomes in adulthood. We examined the potential to reduce socioeconomic gaps in children's reading skills through increasing home reading and preschool attendance among disadvantaged children. METHODS: We drew on data from the nationally representative birth cohort of the Longitudinal Study of Australian Children (N = 5107) to examine the impact of socioeconomic disadvantage (0-1 year) on children's reading skills (8-9 years). An interventional effects approach was applied to estimate the extent to which improving the levels of home reading (2-5 years) and preschool attendance (4-5 years) of socioeconomically disadvantaged children to be commensurate with their advantaged peers, could potentially reduce socioeconomic gaps in children's reading skills. RESULTS: Socioeconomically disadvantaged children had a higher risk of poor reading outcomes compared to more advantaged peers: absolute risk difference = 20.1% (95% confidence interval [CI]: 16.0%-24.2%). Results suggest that improving disadvantaged children's home reading and preschool attendance to the level of their advantaged peers could eliminate 6.5% and 2.1% of socioeconomic gaps in reading skills, respectively. However, large socioeconomic gaps would remain, with disadvantaged children maintaining an 18.3% (95% CI: 14.0%-22.7%) higher risk of poor reading outcomes in absolute terms. CONCLUSION: There are clear socioeconomic disparities in children's reading skills by late childhood. Findings suggest that interventions that improve home reading and preschool attendance may contribute to reducing these inequities, but alone are unlikely to be sufficient to close the equity gap.

Health service utilisation and unmet healthcare needs of Australian children from immigrant families: A population-based cohort study.

Compared with most other Organization for Economic Co-operation and Development (OECD) countries, information about the patterns of health service use for children from immigrant families in Australia is currently limited, and internationally, data on unmet healthcare needs are scarce. This study aims to examine the distribution of health service utilisation and unmet healthcare needs for immigrant children aged 10-11 years in Australia. We drew on data from the Longitudinal Study of Australian Children Birth (B; n = 5,107) and Kindergarten (K; n = 4,983) cohorts. The exposure was family immigration background collected at 0-1 (B-cohort) and 4-5 (K-cohort) years. Outcomes were parent-reported child health service use and unmet healthcare needs (defined as the difference between services needed and services received) at 10-11 years. Logistic regression analyses were used to examine associations between family immigration background and health service use/unmet healthcare needs, adjusting for potential confounders. Results showed that one-third of Australian children (B-cohort: 29.0%; K-cohort: 33.4%) came from immigrant families. There were similar patterns of health service use and unmet healthcare needs between children from English-speaking immigrant and Australian-born families. However, children from non-English-speaking immigrant families used fewer health services, including paediatric, dental, mental health and emergency ward services. There was a disparity between the services used when considering children's health needs, particularly for paediatric specialist services (B-cohort: OR = 2.43, 95% CI 1.11-5.31; K-cohort: OR = 2.72, 95% CI 1.32-5.58). Findings indicate that Australian children from non-English-speaking immigrant families experience more unmet healthcare needs and face more barriers in accessing health services. Further effort is needed to ensure that the healthcare system meets the needs of all families.

A comparison of mood and quality of life among people with progressive neurological illnesses and their caregivers.

The current study was designed to investigate differences in mood and a range of QOL domains among 423 patients and 335 caregivers of people with motor neurone disease (MND), Huntington's disease (HD), Parkinson's, and multiple sclerosis (MS). Patients and caregivers completed an anonymous questionnaire that evaluated their mood (anxiety, depression, fatigue, confusion) and QOL (physical, psychological, social, environment). The results demonstrated that caregivers of people with MND and HD experienced most problems with their mood and QOL compared to caregivers of people in the other illness groups. There were few differences in mood or QOL between patients and caregivers. Patients generally showed greater confusion, physical impairment, and psychological maladjustment. The findings suggest that educational and intervention programs need to be developed to help both patients and their caregivers to adjust and cope with these illnesses, particularly caregivers of people with MND and HD.

The Impact of Policy Modifiable Factors on Inequalities in Rates of Child Dental Caries in Australia.

Background: Poor oral health in childhood can lead to adverse impacts later in life. We aimed to estimate the prevalence and population distribution of childhood dental caries in Australia and investigate factors that might ameliorate inequalities. Methods: Data from the nationally representative birth cohort Longitudinal Study of Australian Children (N = 5107), using questions assessing: The experience of dental caries during each biennial follow-up period (2-3 years to 10-11 years), socioeconomic position (SEP), and policy modifiable oral health factors. Results: The odds of dental caries were higher for children with lowest vs. highest SEP (adjusted OR (adjOR) 1.92, 95% CI 1.49-2.46), and lower where water was fluoridated to recommended levels (adjOR 0.53, 95% CI 0.43-0.64). There was no evidence of an association between caries experience and either reported sugary diet or tooth brushing. When SEP and fluoridation were considered in conjunction, compared to the highest SEP group with water fluoridation children in the lowest SEP with fluoridation had adjOR 1.54 for caries, (95% CI 1.14-2.07), and children in the lowest SEP without fluoridation had adjOR 4.06 (95% CI 2.88-5.42). For patterns of service use: The highest SEP group reported a greater percentage of service use in the absence of caries. Conclusions: Dental caries appears prevalent and is socially distributed in Australia. Policy efforts should consider how to ensure that children with dental caries receive adequate prevention and early care with equitable uptake.

The impact of neurological illness on marital relationships.

The current study investigated the impact of neurological illness on marital relationship satisfaction. Participants numbered 423 patients and 335 carers from motor neurone disease (MND), Huntington's disease (HD), Parkinson's, and multiple sclerosis (MS). The results demonstrated that patients and carers with HD had a significantly lower level of relationship satisfaction and sex life satisfaction than the other three illness groups. Further, patients with HD indicated a significantly higher level of relationship satisfaction than their carers. For MS and MND patients, social support predicted marital relationship satisfaction, and for Parkinson's patients, social support and sex life satisfaction predicted marital relationship satisfaction.

Can a teacher-reported indicator be used for population monitoring of oral language skills at school entry?

PURPOSE: Monitoring oral language skills at the population level would provide valuable data to inform policy decisions to better support children's oral language skills in schools. The Australian Early Development Census (AEDC) is a teacher-rated population measure of early child development that includes a rating of children's oral communication in the classroom (OCC). METHOD: This study evaluates the validity of the OCC indicator for population monitoring of children's oral language skills, capitalising on data from two datasets: the 2012 AEDC cohort (n = 289 973) and a subsample of children from the Longitudinal Study of Australian Children for whom AEDC data were also collected (n = 720). RESULT: Construct validity was demonstrated by showing significant differences in OCC ratings between subpopulations of children who would be expected to differ in terms of oral language skills at school entry (e.g. children with a diagnosed speech-language impairment compared to those with no impairment). OCC ratings were associated with externally validated measures of language, suggesting convergent validity. No relationship was found between OCC ratings and physical health scores, indicating divergent validity. CONCLUSION: The findings support the use and interpretation of the OCC indicator as a tool for population-level monitoring of oral language in Australian school entrants.

Academic outcomes of multilingual children in Australia.

PURPOSE: The Australian educational system is increasingly challenged to meet the needs of multilingual students, who comprise a fifth of the student population. Within the context of a monolingual English curriculum, multilingual children who enter school not yet English proficient may be at risk of experiencing inequitable educational outcomes. METHOD: We examined the relationship between the timing of multilingual children's acquisition of receptive English vocabulary skills and subsequent reading and numeracy outcomes, as well as factors associated with earlier versus later timing of acquisition. Data were drawn from the Kindergarten-cohort (n = 4983) of the Longitudinal Study of Australian Children - a nationally representative, community sample of Australian children. RESULT: Linear regression analyses revealed that multilingual children who begin school with proficient receptive English vocabulary skills, or who acquire proficiency early in schooling, are indistinguishable from their monolingual peers in literacy and numeracy outcomes by 10-11 years. However, later acquisition of receptive English vocabulary skills (i.e. after 6-7 years) was associated with poorer literacy outcomes. In turn, socioeconomic disadvantage and broader language or learning problems predicted this later acquisition of receptive English vocabulary skills. CONCLUSION: All children need to be supported during the early years of school to reach their full educational potential.

The impact of multidimensional disadvantage over childhood on developmental outcomes in Australia.

Background: Understanding the relationship between different aspects of disadvantage over time and domains of child development will facilitate the formulation of more precise policy responses. We examined the association between exposure to aspects of disadvantage over the childhood period (from 0-9 years) and child development at 10-11 years. Methods: We used data from the nationally representative birth cohort of the Longitudinal Study of Australian Children (n = 4979). Generalized linear models with log-Poisson link were used to estimate the association between previously derived disadvantage trajectories (in each of four lenses of sociodemographic, geographic environments, health conditions and risk factors, and a composite of these) and risk of poor child developmental outcomes. Population-attributable fractions were calculated to quantify the potential benefit of providing all children with optimal conditions for each developmental outcome. Results: Trajectories of disadvantage were associated with developmental outcomes: children in the most disadvantaged composite trajectory had seven times higher risk of poor outcomes on two or more developmental domains, compared with those most advantaged. Trajectories of disadvantage in different lenses were varyingly associated with the child development domains of socio-emotional adjustment, physical functioning and learning competencies. Exposure to the most advantaged trajectory across all lenses could reduce poor developmental outcomes by as much as 70%. Conclusions: Exposure to disadvantage over time is associated with adverse child development outcomes. Developmental outcomes varied with the aspects of disadvantage experienced, highlighting potential targets for more precise policy responses. The findings provide evidence to stimulate advocacy and action to reduce child inequities.

More than a snapshot in time: pathways of disadvantage over childhood.

Background: Disadvantage rarely manifests as a single event, but rather is the enduring context in which a child's development unfolds. We aimed to characterize patterns of stability and change in multiple aspects of disadvantage over the childhood period, in order to inform more precise and nuanced policy development. Methods: Participants were from the Longitudinal Study of Australian Children birth cohort (n = 5107). Four lenses of disadvantage (sociodemographic, geographic environment, health conditions and risk factors), and a composite of these representing average exposure across all lenses, were assessed longitudinally from 0 to 9 years of age. Trajectory models identified groups of children with similar patterns of disadvantage over time for each of these lenses and for composite disadvantage. Concurrent validity of these trajectory groups was examined through associations with academic performance at 10-11 years. Results: We found four distinct trajectories of children's exposure to composite disadvantage, which showed high levels of stability over time. In regard to the individual lenses of disadvantage, three exhibited notable change over time (the sociodemographic lens was the exception). Over a third of children (36.3%) were exposed to the 'most disadvantaged' trajectory in at least one lens. Trajectories of disadvantage were associated with academic performance, providing evidence of concurrent validity. Conclusions: Children's overall level of composite disadvantage was stable over time, whereas geographic environments, health conditions and risk factors changed over time for some children. Measuring disadvantage as uni-dimensional, at a single time point, is likely to understate the true extent and persistence of disadvantage.
