Stress reactivity moderates the association between stressful life events and depressive symptoms in adolescents: Results from a population-based study (2024)
Journal Article

A large body of evidence links stressful life events with depression. However, little is understood about the role of perceived impact in this association. We performed regression analysis to investigate whether self-reported stress reactivity (deriv...

Maximizing insights from longitudinal epigenetic age data: Simulations, applications, and practical guidance (2024)
Journal Article

Background: Epigenetic age (EA) is an age estimate, developed using DNA methylation (DNAm) states of selected CpG sites across the genome. Although EA and chronological age are highly correlated, EA may not increase uniformly with time. Departures, k...

DNA methylation mediates the link between adversity and depressive symptoms (2024)
Journal Article

Experiences of childhood adversity can double risk for depression. Although the mechanisms underlying this relationship remain unclear, DNA methylation (DNAm) has emerged as a potential pathway to explain the link between adversity and depression. Th...

Developmental timing of associations among parenting, brain architecture, and mental health (2024)
Journal Article

Importance
Parenting is associated with brain development and long-term health outcomes, although whether these associations depend on the developmental timing of exposure remains understudied. Identifying these sensitive periods can inform when and... Read More about Developmental timing of associations among parenting, brain architecture, and mental health.

Life-course influences of poverty on violence and homicide: 30-year Brazilian birth cohort study (2024)
Journal Article

Background: Homicide is the leading cause of death among young people in Latin America, one of the world's most violent regions. Poverty is widely considered a key cause of violence, but theories suggest different effects of poverty, depending on whe...

Depressive symptoms in adolescence and adult educational and employment outcomes: A structured life course analysis (2024)
Journal Article

Background. Depression is a common mental health disorder that often starts during adolescence, with potentially important future consequences including ‘Not in Education, Employment or Training’ (NEET) status. Methods. We took a structured life cour... Read More about Depressive symptoms in adolescence and adult educational and employment outcomes: A structured life course analysis.

Developing emotional preparedness and mental resilience through high-fidelity simulation: A ‘bridge too far’ for institutions teaching major trauma management and mass-casualty medicine? (2024)
Journal Article

Background: Clinical acumen represents only part of being adequately equipped to attend a major incident. The emotive sights, sounds and smells of these dynamic environments are all-encompassing experiences, and responders must also be armed with the...

How well do parents identify their child's baby teeth? Engagement and accuracy of parent-reported information on a tooth checklist survey (2024)
Journal Article

Objectives: Naturally exfoliated primary teeth are being increasingly collected in child development studies. Most of these odontological collections and tooth biobanks use parent-reported information from questionnaires or tooth checklists to collec...

The relationship between type, timing and duration of exposure to adverse childhood experiences and adolescent self-harm and depression: Findings from three UK prospective population-based cohorts (2024)
Journal Article

Background: Adverse childhood experiences (ACEs) are well-established risk factors for self-harm and depression. However, despite their high comorbidity, there has been little focus on the impact of developmental timing and the duration of exposure t... Read More about The relationship between type, timing and duration of exposure to adverse childhood experiences and adolescent self-harm and depression: Findings from three UK prospective population-based cohorts.

Ambulance clinicians implementing evidence-based practice: Mind the gap! Attitudes, perceptions and experiences of student paramedics (2023)
Journal Article

Background: Evidence-based practice (EBP) represents the conscientious and judicious use of the best contemporaneous evidence in partnership with patient values and clinical expertise to guide healthcare professionals. As a result, EBP is a recommend... Read More about Ambulance clinicians implementing evidence-based practice: Mind the gap! Attitudes, perceptions and experiences of student paramedics.

Association between the timing of childhood adversity and epigenetic patterns across childhood and adolescence: findings from the Avon Longitudinal Study of Parents and Children (ALSPAC) prospective cohort (2023)
Journal Article

Background: Childhood adversity is a potent determinant of health across development and is associated with altered DNA methylation signatures, which might be more common in children exposed during sensitive periods in development. However, it remain...

Home and epigenome: How DNA methylation could explain the association between housing quality and depression (2023)
Journal Article

Poor housing quality is a consistent risk factor for mental health problems. Despite the large body of evidence for housing’s relationship with mental health, housing quality as an environmental stressor has not yet been investigated with regards to... Read More about Home and epigenome: How DNA methylation could explain the association between housing quality and depression.

Sensitive periods for the effect of child maltreatment on psychopathology symptoms in adolescence (2023)
Journal Article

Introduction: Child maltreatment is among the strongest risk factors for mental disorders. However, little is known about whether there are ages when children may be especially vulnerable to its effects. We sought to identify potential sensitive peri...

Testing lifecourse theories characterising associations between maternal depression and offspring depression in emerging adulthood: The Avon Longitudinal Study of Parents and Children (2022)
Journal Article

Background: Maternal depression is a major determinant of offspring mental health. Yet, little is understood about how the duration and timing of maternal depression shapes youth risk for depressive symptoms, which if understood could inform when bes...

Socioeconomic changes predict genome-wide DNA methylation in childhood (2022)
Journal Article

Childhood socioeconomic position (SEP) is a major determinant of health and well-being across the entire life course.
