objective: Positive childhood experiences (PCEs), that occur within secure and nurturing social environments, are fundamental to healthy physical, social-emotional, and cognitive development. However, reliable measures of these experiences are not yet widely available. We used data from the Longitudinal Study of Australian Children (LSAC) to empirically represent and psychometrically evaluate 3 primary domains of PCEs defined within the Health Outcomes from Positive Experiences (HOPE) framework, specifically: 1) nurturing and supportive relationships; 2) safe and protective environments and; 3) constructive social engagement and connectedness. Methods: LSAC is a nationally representative cohort that has followed young Australians from birth since 2004. LSAC data were used to represent the 3 primary HOPE-PCEs domains (birth to 11 years) across 4 inter-related PCEs constructs: 1) positive parenting, 2) trusting and supportive relationships, 3) supportive neighborhood and home learning environments, and 4) social engagement and enjoyment. Confirmatory factor analysis was used to test the proposed 4-factor structure. Predictive validity was examined through associations with mental health problems and academic difficulties at 14 to 15 years. Results: The 4-factor structure was supported by empirical data at each time point. Higher exposure to PCEs across each domain was associated with lower reporting of mental health problems (ft = --0.20 to --2.05) and academic difficulties (/3 = -0.01 to -0.13) in adolescence. Conclusions: The 4 LSAC-based HOPE-PCEs have sufficient internal coherence and predictive validity to offer a potentially useful way of conceptualizing and measuring PCEs in future cohort studies and intervention trials aiming to enhance the understanding of, and mitigate the negative impacts of, adverse childhood experiences.

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. 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. 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. 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.

The first 5 years of a child's life are crucial in laying the foundation for their health and developmental trajectory into adulthood. These early years are especially influenced by the surrounding environments in which children live and grow. A large international body of evidence demonstrates that children who experience disadvantage tend to fall increasingly behind over time. At the societal level, these inequities can cause substantial social burdens and significant costs across health, education, and welfare budgets. A contributing factor is that children experiencing adversity are less likely to have access to the environmental conditions that support them to thrive. Many of these factors are modifiable at the community or place level. We argue for three key—though not exhaustive—ideas that collectively could achieve more equitable outcomes for children facing disadvantage and experiencing adversity: 1. Adopt a social determinants approach to conceptualizing disadvantage; 2. Stack existing, evidence-based government and nongovernment service interventions/programs that operate at the local or community level; and 3. Use data and evidence to focus improvements for more equitable and adaptive systems. We conclude that if adopted, these 3 ideas could contribute to the ability of local communities and networks to identify and respond to factors that address early childhood inequalities.

Exposure to early adversity carries long term harmful consequences for children's health and development. This study aims to 1) estimate the prevalence of childhood adversity for Australian children from infancy to 10–11 years, and 2) document inequalities in the distribution of adversity according to socioeconomic position (SEP), Indigenous status, and ethnicity. Adversity was assessed every 2 years from 0–1 to 10–11 years in the nationally representative birth cohort of the Longitudinal Study of Australian Children (N = 5107). Adversity included legal problems; family violence; household mental illness; household substance abuse; harsh parenting; parental separation/divorce; unsafe neighborhood; family member death; and bullying (from 4 to 5 years). Adversities were examined individually and summed for a measure of multiple adversity (2+ adverse experiences). By 10–11 years, 52.8% (95% confidence interval [CI] 51.0–54.7) of children had been exposed to 2 or more adversities. When combined with low SEP, children from ethnic minority and from Indigenous backgrounds had 4 to 8 times the odds of exposure to 2 or more adversities than children from higher SEP Anglo-Euro backgrounds, respectively (odds ratio [OR] 4.3, 95% CI 2.8–6.6 and OR 8.1, 95% CI 4.4–14.8). Ethnic minority and Indigenous children from higher SEP backgrounds had increased odds of exposure to multiple adversity than similarly advantaged Anglo-Euro children (OR 1.8, 95% CI 1.4–2.3 and OR 2.3, 95% CI 1.3–4.3, respectively). Addressing early adversity is a significant opportunity to promote health over the life course, and reduce health inequalities experienced by marginalized groups of children. [ABSTRACT FROM AUTHOR]

Major policy reforms were instigated in 2008 in Australia to ensure that all children have access to a preschool program in the year before starting school. The Australian Early Development Census (AEDC) provides a means of monitoring the impact of these reforms at the population level, as teachers of all children in their first year of school retrospectively report on children's preschool experiences every three years. Early indications from AEDC data spanning the preschool years of 2008–2011 indicated that the proportion of children attending preschool remained relatively stable over this period. In this short communication, we update this with analysis of preschool trends from 2008 to 2014. We find evidence of increasing preschool attendance over this longer time frame (80.43% in 2008, compared to 91.30% in 2014; OR 2.53, 99% CI 2.44–2.62). Consistent with earlier data, children from disadvantaged communities had higher odds of non-attendance, compared to those living in the most advantaged communities (OR 2.94, 99% CI 2.74–3.15). In 2014, children who did not attend preschool were also disproportionately Indigenous and from non-English speaking backgrounds. Findings suggest that participation in preschool appears to have increased, concurrent to government efforts to promote participation through universal access. Engaging the most vulnerable families in preschool programs remains a major challenge that requires continued policy focus. [ABSTRACT FROM AUTHOR]

- Abstract
Pediatric persistent pain is associated with poorer physical and psychosocial functioning in children, as well as immediate and long-term societal costs. Onset typically occurs in early adolescence, suggesting that late childhood is a key window for identifying potential intervention targets before pain symptoms become entrenched. This study used population-based data from the Longitudinal Study of Australian Children (n = 3,812) and adopted a biopsychosocial and ecological systems approach to investigate child, family, and sociodemographic factors associated with pain problems in children transitioning to adolescence. The prevalence of at least weekly parent-reported pain in the study sample was approximately 5% at 10 to 11 years of age, and pain continued at 12 to 13 years of age for 40% of these children. Key factors at 10 to 11 years that uniquely predicted parent-reported pain problems at 12 to 13 years were frequency of previous pain (1-3 times weekly: odds ratio [OR] = 7.49; 95% confidence interval [CI], 4.3-13.0; 4-7 times weekly: OR = 17.8; 95% CI, 8.7-36.5) and sleep difficulties (OR = 1.86; 95% CI, 1.16-2.97). This study highlights the importance of early intervention for persistent pain in childhood, because pain complaints in late childhood tend to persist into early adolescence.
Perspective: This article used a biopsychosocial and ecological systems approach to understanding predictors of pain problems during the transition to adolescence within a nationally representative community-based cohort. Sleep difficulties at 10 to 11 years uniquely predicted pain at ages 12 to 13 years, suggesting that early intervention using sleep interventions may be a promising direction for future research.

- Abstract
Longitudinal cohorts can provide timely and cost-efficient evidence about the best points of health service and preventive interventions over the life course. Working systematically across cohorts has the potential to further exploit these valuable data assets, such as by improving the precision of estimates, enhancing (or appropriately reducing) confidence in the replicability of findings, and investigating interrelated questions within a broader theoretical model. In this conceptual review, we explore the opportunities and challenges presented by multi-cohort approaches in life course research. Specifically, we: 1) describe key motivations for multi-cohort work and the analytic approaches that are commonly used in each case; 2) flag some of the scientific and pragmatic challenges that arise when adopting these approaches; and 3) outline emerging directions for multi-cohort work in life course research. Harnessing their potential while thoughtfully considering limitations of multi-cohort approaches can contribute to the robust and granular evidence base needed to promote health and wellbeing over the life span. • Longitudinal cohorts play an essential role in understanding health over the life course. • Drawing multiple cohorts together for analysis can further enhance this contribution. • Key challenges also need to be recognised and carefully managed.

Participation in a preschool program in the year before starting school can promote children’s healthy development, and has the potential to reduce inequities in developmental outcomes for at-risk subpopulations. In Australia, boosting preschool attendance has emerged as a national policy priority. In this paper, we draw on data from the Australian Early Development Census (AEDC) to describe preschool attendance in two sequential population cohorts, with preschool experiences in 2008 and 2011 reported retrospectively by teachers of children in their first year of school. Overall, findings show that the proportion of children attending preschool remained relatively stable between the two AEDC cohorts (in 2008, preschool attendance ranged from 57.0% to 85.8% across the states and territories, while in 2011, attendance ranged from 49.2% to 93.7%). At a subpopulation level, children from non-English speaking and Indigenous backgrounds and children living in disadvantaged communities all had substantially higher odds of not attending preschool in both 2008 and 2011. These findings highlight the need to maintain policy attention on efforts to further reduce barriers to preschool access for at-risk subpopulations, and the value of monitoring population trends in preschool attendance to better inform policy and service provision.

Aim DNA library preparation for next generation sequencing (NGS) consists of several hundred material transfer and wash steps, which are time consuming, labor intensive, and increase the risk of repetitive strain injury. Robotic liquid handlers can automate and standardize library preparation, but few HLA laboratories have experience with high-complexity robotic platforms. We sought to evaluate the use of robotics for library preparation in conjunction with a NGS based HLA typing assay. Methods A Beckman Coulter Biomek NXp Span-8 robotic liquid handler was acquired along with the vendor supplied robotics method for the Illumina TruSight HLA v2 sequencing panel. The robotics method was first optimized with a series of runs using water, 50% glycerol, 85% ethanol, and AMPure beads. Next, DNA and reagents were run to identify sample viscosity and reagent issues. After each run, issues were communicated to the vendor for method improvement. The finalized method was run on 78 DNA samples over seven runs to assess the quality of normalization, pooling, sequencing, and reproducibility of results. Results Robotic issues were encountered with pipette calibration, labware definitions, proper labware selection, and efficiency. To add complexity, these issues had subtle compounding effects on the overall success of the method, which required that each be addressed individually and in detail. Eleven versions of the method were subsequently produced and tested to ensure robustness and consistency. The finalized method produced consistent high quality sequencing metrics on the NGS typing platform which agreed with the known HLA typing results. Conclusions Detailed documentation of issues by lab staff and clear communication with the vendor allowed for a rapid and iterative improvement of the robotics method. The lessons learned during the implementation process formed a roadmap that allowed for successful implementation of a robotics platform for NGS based HLA typing. [ABSTRACT FROM AUTHOR]

A growing body of evidence suggests that engagement with quality early childhood education and care (ECEC) programs such as preschool can enhance children’s early development. The Australian Early Development Census (AEDC) provides a unique opportunity to explore the relationship between ECEC and children’s developmental outcomes in a full population cohort of Australian school entrants. The AEDC is a teacher-rated checklist that provides data on ECEC experiences in the year before starting school, as well as five important domains of child development at school entry: physical health and wellbeing, social competence, emotional maturity, language and cognitive skills, and communication skills and general knowledge. In 2009, the AEDC was completed for 97.5% of Australian children in their first year of formal schooling ( N = 261,147; M = 5 years, 7 months of age). Logistic regression analyses revealed that attendance at preschool was associated with reduced odds (OR = 0.69, p < 0.001 to OR = 0.40, p < 0.001) of being in the vulnerable range (<10th percentile) on four of the five AEDC domains (with the exception of emotional maturity; OR = 0.89, p = 0.002), compared to other ECEC experiences, or care exclusively by parents. Subsequent analyses revealed that this effect was evident for children living in both advantaged and disadvantaged communities. Together, the results suggest that engagement with preschool programs in Australia may present a plausible, equitable, and modifiable approach to improving children's developmental outcomes.

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. 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. 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). 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. • Income supplements provided to lower-income households may improve children's development. • Household income supplements may also be beneficial to parental mental health. • The absolute reduction in risk of poor outcomes ranged between 0.8% and 2.8%. • Household income supplements alone are insufficient to eliminate child inequities. • Stacking multiple complementary interventions over the life course is needed.
