Cumulative Environmental Risk in Early Life: Associations With Schizotypy in Childhood
No full textBackground and Hypothesis: Psychotic disorders are associated with a growing number of recognized environmental exposures. Cumulative exposure to multiple environmental risk factors in childhood may contribute to the development of different patterns of schizotypy evident in early life. Hypotheses were that distinct profiles of schizotypy would have differential associations with a cumulative score of environmental risk factors. Study Design: We prospectively examined the relationship between 19 environmental exposures (which had demonstrated replicated associations with psychosis) measured from the prenatal period through to age 11 years, and 3 profiles of schizotypy in children (mean age = 11.9 years, n = 20 599) that have been established in population data from the New South WalesChild Development Study. Multinomial logistic regression was used to examine associations between membership in each of 3 schizotypy profiles (true schizotypy, introverted schizotypy, and affective schizotypy) and exposure to a range of 19 environmental risk factors for psychosis (both individually and summed as a cumulative environmental risk score [ERS]), relative to children showing no risk. Results: Almost all environmental factors were associated with at least 1 schizotypy profile. The cumulative ERS was most strongly associated with the true schizotypy profile (OR = 1.61, 95% CI = 1.52–1.70), followed by the affective (OR = 1.33, 95% CI = 1.28–1.38), and introverted (OR = 1.32, 95% CI = 1.28–1.37) schizotypy profiles. Conclusions: Consistent with the cumulative risk hypothesis, results indicate that an increased number of risk exposures is associated with an increased likelihood of membership in the 3 schizotypy profiles identified in middle childhood, relative to children with no schizotypy profile.Kirstie O, Hare, Oliver Watkeys, Tyson Whitten, Kimberlie Dean, Kristin R.

No full textParental and community risk factors for childhood self-harm thoughts and behaviours
Full text linkBackground: Childhood self-harm is rare but increasing in frequency. Little is known about risk factors specifically for self-harm in preteen children. Methods: We examined self-harm thoughts and behaviours in children aged 3–14 years in association with parental and community-level risk factors, using a large general population-based record linkage sample (n = 74,479). Results: Parental factors were strongly associated with childhood self-harm, with over three-quarters of children with self-harm having a parent with a history of mental disorder and/or criminal offending. Community-level factors (socioeconomic deprivation, remote or regional location, and neighbourhood crime rate) were not associated with childhood self-harm after adjustment for confounding factors. Limitations: Measures of self-harm thoughts and behaviours derived from administrative data likely underestimate the prevalence of self-harm in the population. Conclusions: Intergenerational transmission of risk factors is likely an important contributor to childhood self- harm.Kirstie O'Hare, Oliver Watkeys, Tyson Whitten, Kimberlie Dean, Kristin R.

Forecasting childhood adversities from conditions of birth
Full text linkFirst published: 02 February 2022BACKGROUND: 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.Melissa J. Green, Oliver J.

Cumulative environmental risk in early life is associated with mental disorders in childhood
Full text linkBackground: No single environmental factor is a necessary or sufficient cause of mental disorder; multifactorial and transdiagnostic approaches are needed to understand the impact of the environment on the development of mental disorders across the life course. Method: Using linked multi-agency administrative data for 71 932 children from the New South Wales Child Developmental Study, using logistic regression, we examined associations between 16 environmental risk factors in early life (prenatal period to <6 years of age) and later diagnoses of mental disorder recorded in health service data (from age 6 to 13 years), both individually and summed as an environmental risk score (ERS). Results: The ERS was associated with all types of mental disorder diagnoses in a dose-response fashion, such that 2.8% of children with no exposure to any of the environmental factors (ERS = 0), compared to 18.3% of children with an ERS of 8 or more indicating exposure to 8 or more environmental factors (ERS ⩾ 8), had been diagnosed with any type of mental disorder up to age 13-14 years. Thirteen of the 16 environmental factors measured (including prenatal factors, neighbourhood characteristics and more proximal experiences of trauma or neglect) were positively associated with at least one category of mental disorder. Conclusion: Exposure to cumulative environmental risk factors in early life is associated with an increased likelihood of presenting to health services in childhood for any kind of mental disorder. In many instances, these factors are preventable or capable of mitigation by appropriate public policy settings.Kirstie O, Hare, Oliver Watkeys, Tyson Whitten, Kimberlie Dean, Kristin R.

Oliver Heaviside\u27s electromagnetic theory
Full text link\ua9 2018 The Author(s). The year 2018 marks the 125th anniversary of the first of three published volumes on electromagnetic theory by the eminent Victorian electrical engineer, physicist and mathematician, Oliver Heaviside FRS. This commemorative issue of Philosophical Transactions of the Royal Society A celebrates the publication of this work by collecting papers on a broad spectrum across the field of electromagnetic theory, including innovative research papers interspersed between historical perspectives and relevant reviews. Heaviside was a remarkable man, an original thinker with brilliant mathematical powers and physical insight who made many significant contributions in his fields of interest, though he is remembered primarily for his \u27step function\u27, commonly used today in many branches of physics, mathematics and engineering. Here, we celebrate the man and his work by illustrating his major contributions and highlighting his great success in solving some of the great telegraphic engineering problems of the Victorian era, in part due to his development and detailed understanding of the governing electromagnetic theory. We celebrate his Electromagnetic theory: three volumes of insights, techniques and understanding from mathematical, physical and engineering perspectives-as dictated by J. C. Maxwell FRS, but interpreted, reformulated and expanded by Heaviside to advance the art and science of electrical engineering beyond all expectations.This article is part of the theme issue \u27Celebrating 125 years of Oliver Heaviside\u27s \u27Electromagnetic Theory\u27\u27
