Early life influences on child weight outcomes in the Study to Explore Early Development.

ABSTRACT: We examined associations between child body mass index at 2-5?years and maternal pre-pregnancy body mass index, gestational weight gain, and rapid weight gain during infancy in children with autism spectrum disorder, developmental delays, or population controls. The Study to Explore Early Development is a multi-site case-control study of children, aged 2-5?years, classified as autism spectrum disorder ( n?=?668), developmental delays ( n?=?914), or population controls ( n?=?884). Maternal gestational weight gain was compared to the Institute of Medicine recommendations. Rapid weight gain was a change in weight-for-age z-scores from birth to 6?months?>?0.67 standard deviations. After adjusting for case status, mothers with pre-pregnancy overweight/obesity were 2.38 times (95% confidence interval: 1.96-2.90) more likely, and mothers who exceeded gestational weight gain recommendations were 1.48 times (95% confidence interval: 1.17-1.87) more likely, to have an overweight/obese child than other mothers ( P?

Project description:IntroductionEarly childhood experiences have a lifelong impact on a child's future. Social and environmental experiences and interactions have a profound relational effect on children's physical and mental health which transfers agency to parents, caregivers and duty-bearers to care for the child's welfare. In the Australian context early child development indices have been in decline in some communities. Hence, there is a sense of urgency to reverse these trends from an integrated perspective. A multisector, multi component program of interventions named A Good Start in Life is proposed and is being tested in the Australian Capital Territory across suburbs with high levels of early childhood development disadvantage. The aim of this study is to evaluate the outcomes and processes related to targeted interventions, designed to integrate child and family services within the local district and embed allied health programs into early childhood education, care services and playgroups.Methods and analysisThe Good Start in Life study will use a quasi-experimental design (with a matched control geographical area) consisting of a combination of interventions that will build multisectoral collaboration across education, health and social services that connect and support families with children from birth to 5 years. The control area will be matched on demographic characteristics and early child development outcomes and trends over the pre-intervention period. Evaluation data will be collected at baseline, and then on an annual basis for a further three years. A mixed methods approach will be used to evaluate delivery processes: quantitative (checklists, questionnaires) and qualitative methods (observations, focus groups and key stakeholder interviews). Effectiveness of the programme will be evaluated by comparing early child development outcomes between the comparator areas from the Australian Early Development Census in 2024. The primary focus will be on reducing the number of children who are developmentally vulnerable on at least one early development index (EDI). Separate tests will be conducted for significant differences in the percentage of children at risk in each of the five individual EDI domains. These domains are physical health and wellbeing, social competence, emotional maturity, language and cognitive skills, and communication and general knowledge.Trial registrationACTRN12621001140842.

Project description:Immune system abnormalities have been widely reported among children with autism spectrum disorder (ASD), which may increase the risk of childhood infections. The Study to Explore Early Development (SEED) is a multisite case-control study of children aged 30-69 months, born in 2003-2006. Cases are children previously diagnosed and newly identified with ASD enrolled from education and clinical settings. Children with a previously diagnosed non-ASD developmental condition were included in the developmental delay/disorder (DD) control group. The population (POP) control group included children randomly sampled from birth certificates. Clinical illness from infection during the first 28 days ("neonatal," from medical records) and first three years of life (caregiver report) in cases was compared to DD and POP controls; and between cases with and without regression. Children with ASD had greater odds of neonatal (OR = 1.8; 95%CI: 1.1, 2.9) and early childhood infection (OR = 1.7; 95%CI: 1.5, 1.9) compared to POP children, and greater odds of neonatal infection (OR = 1.5; 95%CI: 1.1, 2.0) compared to DD children. Cases with regression had 1.6 times the odds (95%CI: 1.1, 2.3) of caregiver-reported infection during the first year of life compared to cases without regression, but neonatal infection risk and overall early childhood infection risk did not differ. Our results support the hypothesis that children with ASD are more likely to have infection early in life compared to the general population and to children with other developmental conditions. Future studies should examine the contributions of different causes, timing, frequency, and severity of infection to ASD risk.

LAY SUMMARY: We looked at infections during early childhood in relation to autism spectrum disorder (ASD). We found that children with ASD were more likely to have an infection in the first 28 days of life and before age three compared to children with typical development. Children with ASD were also more likely than children with other developmental delays or disorders to have an infection in the first 28 days of life.
