ItemAssociations between early maternal behaviours and child language at 36 months in a cohort experiencing adversity(WILEY, 2019-01)BACKGROUND: Variations in parenting, more specifically less responsive and more directive parenting, contribute to language difficulties for children experiencing adversity. Further investigation of associations between specific responsive and directive behaviours and child language is required to understand how behaviours shape language over time within different populations. As language is dyadic, further exploration of how mother-child interactions moderate associations is also important. AIMS: To investigate associations between specific responsive and directive maternal behaviours, the quality of mother-child interaction (fluency and connectedness) and child language in a cohort experiencing adversity. METHODS & PROCEDURES: Pregnant women experiencing adversity were recruited from maternity hospitals in Australia. At 12 months, videos of mother-infant free play were collected. Videos were coded for maternal behaviours and fluency and connectedness (n = 249). At 36 months, child language was measured using a standardized language test. Linear regression models were used to examine associations and the moderating role of fluency and connectedness was explored. OUTCOMES & RESULTS: Responsive yes/no questions were positively associated with language scores. Unsuccessful redirectives were negatively associated with language scores. The moderation effect of fluency and connectedness was equivocal in the current data. CONCLUSIONS & IMPLICATIONS: Findings reproduce and extend previous research highlighting key features of mother-child interactions associated with child language trajectories. Findings also augment knowledge of risk and protective factors related to language for children experiencing adversity and highlight where targeted interventions might be successful.

ItemTrends in the prevalence and distribution of teacher-identified special health-care needs across three successive population cohorts(WILEY, 2019-03)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.

ItemThe Impact of Policy Modifiable Factors on Inequalities in Rates of Child Dental Caries in Australia(MDPI, 2019-06-01)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.

ItemDriving Precision Policy Responses to Child Health and Developmental Inequities(Mary Ann Liebert, 2019-01-01)The growing evidence base on the extent of and opportunities to reduce inequities in children's health and development still lacks the specificity to inform clear policy decisions. A new phase of research is needed that builds on contemporary directions in precision medicine to develop precision policy making; with the aim to redress child inequities. This would include identifying effective interventions and their ideal time point(s), duration, and intensity to maximize impact. Drawing on existing data sources and innovations in epidemiology and biostatistics would be key. The economic and social gains that could be achieved from reducing child inequities are immense.
