Educational pathways and outcomes for care‐experienced children: A 16‐year longitudinal study
Children who are removed from their birth families during childhood—termed care‐experienced—can be at risk for lower educational attainment and poorer school experiences, often linked to deprivation and behavioural factors. However, research often uses aggregated measures that obscure the complexities of care (e.g. timing, and placements) and evidence is needed to understand the factors that could explain the link between care‐experience and atta…
Childhood trauma, adolescent risk behaviours and cardiovascular health indices in the 2004 Pelotas Birth Cohort
BACKGROUND: Childhood trauma has been associated with increased risk of substance use and poor sleep, with these factors linked to subsequent poor cardiovascular health. However, there has been little longitudinal research exploring these associations in adolescence, especially in low- and middle-income countries (LMICs). To address this, we investigated longitudinal pathways from trauma to risk behaviours and cardiovascular health indices among …
Childhood conduct problems, potential snares in adolescence, and problematic substance use in Brazil
Childhood conduct problems are associated with problematic substance use in adulthood; however, little is known about what might explain these associations outside of high-income countries where the majority of research is conducted. Data were analyzed from 4599 young people from the 1993 Pelotas Birth Cohort in Brazil. The exposure was conduct problems (age 11 years). Outcomes included hazardous alcohol consumption and illicit drug use (age 22 y…
Counterfactual Mediation Analysis with a Latent Class Exposure
Latent classes are a useful tool in developmental research, however there are challenges associated with embedding them within a counterfactual mediation model. We develop and test a new method "updated pseudo class draws (uPCD)" to examine the association between a latent class exposure and distal outcome that could easily be extended to allow the use of any counterfactual mediation method. UPCD extends an existing group of methods (based on pse…
Emotional dysregulation in childhood and disordered eating and self‐harm in adolescence: Prospective associations and mediating pathways
BACKGROUND: Emotional dysregulation may be a risk factor for disordered eating and self-harm in young people, but few prospective studies have assessed these associations long-term, or considered potential mediators. We examined prospective relationships between childhood emotional dysregulation and disordered eating and self-harm in adolescence; and social cognition, emotional recognition, and being bullied as mediators. METHODS: We analysed Avo…
Maternal postnatal depressive symptoms and offspring emotional and behavioral development at age 7 years in a U.K. birth cohort: The role of paternal involvement
There is considerable variability in developmental outcomes of children whose mothers experience depression. Few longitudinal studies have examined contributions of paternal involvement in the association between maternal postnatal depression (PND) and offspring development. We examined pathways from maternal PND at 8 weeks (Edinburgh Postnatal Depression Scale; total score) to offspring emotional and behavioral development at 7 years (Strengths …
The Influence of Alcohol Consumption on Fighting, Shoplifting and Vandalism in Young Adults
Experimental studies support the conventional belief that people behave more aggressively whilst under the influence of alcohol. To examine how these experimental findings manifest in real life situations, this study uses a method for estimating evidence for causality with observational data-'situational decomposition' to examine the association between alcohol consumption and crime in young adults from the Avon Longitudinal Study of Parents and …
Alcohol consumption and internalising disorders in young adults of ALSPAC: A population-based study
Introduction Depression and harmful alcohol consumption contribute significantly to the global health burden, but in young adults, this relationship is under-researched and conflicted. The aim of this study was to determine the sex-based prevalence and the association between internalising disorders such as depression and alcohol use disorders. Method Using the Avon Longitudinal Study of Parents and Children, we assessed the sex-specific prevalen…
