Plasma Glial Fibrillary Acidic Protein (GFAP) shows age-dependent associations with externalizing psychopathology and atypical brain connectivity
Abstract Externalizing disorders are common neurodevelopmental conditions, yet their underlying biology is not fully understood. Integrating peripheral biomarkers with brain imaging offers a powerful approach to elucidate the pathophysiology of these disorders.
Bidirectional associations between parental negativity and child externalising problems: Social support and neighbourhood cohesion as moderators
INTRODUCTION Externalising behaviours (e.g., conduct problems, aggression) are one of the most common mental-health problems in childhood (Sacco et al., 2022), predicting adverse outcomes, including poor academic achievement, substance use, lack of employment and criminality (Colman et al., 2009; Erskine et al., 2016). Associations between externalising behaviour and parent–child relationships are well-established.
Association of multiple indicators of pubertal timing with depressive symptoms and depression in adolescent girls
There is robust evidence for an association between early pubertal timing in girls and depressive symptoms; Reference Galvao, Silva, Zimmermann, Souza, Martins and Pereira1–Reference Ullsperger and Nikolas3 however, there continues to be substantial variation in the measurement of pubertal timing in the literature. Reference Hayward4,Reference Negriff and Susman5 As puberty is a developmental process and not a fixed event, its measurement can pose a methodological challenge.
Pubertal timing, body dissatisfaction and self-image: a prospective cohort study
Strengths and limitations of this study Used a large prospective cohort study with robust data collection methods. Assessment of an objective measure of pubertal timing (age at peak height velocity) in both sexes. Generalisability may be limited due to under-representation of ethnic minorities in the cohort, impacting cross-cultural applicability.
The association of modifiable and socio‐demographic factors with first transitions from smoking to exclusive e‐cigarette use, dual use or no nicotine use: Findings from the Avon Longitudinal Study of Parents and Children United Kingdom birth cohort
INTRODUCTION Tobacco control approaches in the United Kingdom (UK) have achieved great success given smoking rates have been declining since records began in 1974 [1]. However, harm reduction is essential for individuals who smoke tobacco and have either struggled to quit or do not intend to. One potential harm reduction tool is electronic cigarettes (e-cigarettes), which may support smoking cessation.

Systematic Review of Clinical Prediction Models for the Risk of Emergency Caesarean Births
3.2.4.2 Handling Predictors Continuous predictors are optimal when not dichotomised [19]; 38 studies with well-described handling were low-risk, whilst 25 studies, with five introducing bias through dichotomisation and 20 inadequately explaining cut-off methods, were high risk. The methods used to select predictors is extremely important.

Using instruments for selection to adjust for selection bias in Mendelian randomization
1 INTRODUCTION Mendelian randomization (MR) uses genetic data to assess the causal relationship between a modifiable exposure and an outcome of interest.1, 2 MR is an application of instrumental variables analysis where genetic variants are used as instruments. The instrumental variable framework allows MR to account for unobserved confounding, which is a primary concern in other types of observational studies.

Incident psychotic experiences following self‐reported use of high‐potency cannabis: Results from a longitudinal cohort study
INTRODUCTION Globally, cannabis is the most commonly used internationally regulated drug [1]. The primary psychoactive component of cannabis is Δ-9-tetrahydrocannabinol (THC), and cannabis with higher concentrations of THC is described as high-potency. Policy liberalization has been accompanied by proliferation of high-potency cannabis in legal markets [2], and THC concentrations have increased in markets where cannabis remains illegal [3].

The antecedents and outcomes of persistent and remitting adolescent depressive symptom trajectories: a longitudinal, population-based English study
Summary Background Depression often first emerges in adolescence and, for many, is a lifelong disorder. The long-term clinical course of depression is highly variable. We aimed to examine the adult outcomes of adolescent-onset trajectories of clinically significant depressive symptoms and to identify factors differentiating trajectories that persist and desist in adulthood.
Cognitive style and drinking to cope: A prospective cohort study
Abstract Background and Aims Having a negative cognitive style may lead someone to feel hopeless about his or her situation and be more likely to engage in coping-motivated drinking. We, therefore, aimed to investigate the association between cognitive style and drinking to cope. Design Prospective cohort study. Setting The former Avon Health Authority in South West England. Participants A total of 1681 participants of the Avon Longitudinal Study of Parents and Children.

Testing the validity of national drug surveys: comparison between a general population cohort and household surveys
INTRODUCTION Globally, substance misuse contributes to 27.8 million disability adjusted life years (DALYs) [1]. Exposure to illicit drugs during adolescence is associated with increased risk of lifetime drug dependence, mental health problems, injury, poorer educational performance [2, 3] and negative socioeconomic outcomes [3-5]. Reliable measures of illicit drug use are vital for developing effective policy and treatment programmes [6].

Prevalence of steatosis and fibrosis in young adults in the UK: a population-based study
Summary Background The estimated worldwide prevalence of non-alcoholic fatty liver disease (NAFLD) in adults is 25%; however, prevalence in young adults remains unclear. We aimed to identify the prevalence of steatosis and fibrosis in young adults in a sample of participants recruited through the Avon Longitudinal Study of Parents and Children (ALSPAC), based on transient elastography and controlled attenuation parameter (CAP) score.
Maternal dietary patterns during pregnancy and intelligence quotients in the offspring at 8 years of age: Findings from the ALSPAC cohort
Abstract Dietary intake during pregnancy may influence child neurodevelopment and cognitive function. This study aims to investigate the associations between dietary patterns obtained in pregnancy and intelligence quotients (IQ) among offspring at 8 years of age. Pregnant women enrolled in the Avon Longitudinal Study of Parents and Children completed a food frequency questionnaire at 32 weeks' gestation (n = 12,195). Dietary patterns were obtained by cluster analysis.
Pathways between early‐life adversity and adolescent self‐harm: the mediating role of inflammation in the Avon Longitudinal Study of Parents and Children
Abstract Background Adverse childhood experiences (ACEs) such as physical and emotional abuse are strongly associated with self‐harm, but mechanisms underlying this relationship are unclear. Inflammation has been linked to both the experience of ACEs and self‐harm or suicide in prior research. This is the first study to examine whether inflammatory markers mediate the association between exposure to ACEs and self‐harm.
Predictors of future suicide attempt among adolescents with suicidal thoughts or non-suicidal self-harm: a population-based birth cohort study
Summary Background Suicidal thoughts and non-suicidal self-harm are common in adolescents and are strongly associated with suicide attempts. We aimed to identify predictors of future suicide attempts in these high-risk groups. Methods Participants were from the Avon Longitudinal Study of Parents and Children, a population-based birth cohort study in the UK. The sample included 456 adolescents who reported suicidal thoughts and 569 who reported non-suicidal self-harm at 16 years of age.

What distinguishes adolescents with suicidal thoughts from those who have attempted suicide? A population‐based birth cohort study
Much of the existing research in this area has been limited to small and/or unrepresentative samples. Previous studies have also typically relied on retrospective reporting of the occurrence and timing of risk factors which may be subject to recall bias. The present study uses data from a large UK population‐based birth cohort to (a) explore risk factors for adolescent suicidal ideation and attempts and (b) identify factors that distinguish between these groups.

What distinguishes adolescents with suicidal thoughts from those who have attempted suicide? A population‐based birth cohort study
Background Only one‐third of young people who experience suicidal ideation attempt suicide. It is important to identify factors which differentiate those who attempt suicide from those who experience suicidal ideation but do not act on these thoughts. Methods Participants were 4,772 members of the Avon Longitudinal Study of Parents and Children (ALSPAC), a UK population‐based birth cohort. Suicide ideation and attempts were assessed at age 16 years via self‐report questionnaire.
Association of Combined Patterns of Tobacco and Cannabis Use in Adolescence With Psychotic Experiences
Key Points Question Are patterns of adolescent cigarette and cannabis use differentially associated with subsequent onset of psychotic experiences? Findings In this longitudinal cohort study of 3328 adolescents, there is evidence that both cannabis and cigarette use are associated with subsequent psychotic experiences prior to adjusting for confounders. However, after adjusting, the associations for cigarette-only use attenuated substantially, whereas those for cannabis use remained consistent.

A structured approach to hypotheses involving continuous exposures over the life course
Background: Epidemiologists are often interested in examining different hypotheses for how exposures measured repeatedly over the life course relate to later-life outcomes. A structured approach for selecting the hypotheses most supported by theory and observed data has been developed for binary exposures. The aim of this paper is to extend this to include continuous exposures and allow for confounding and missing data.
Association between polygenic risk scores for attention-deficit hyperactivity disorder and educational and cognitive outcomes in the general population
Background: Children with a diagnosis of attention-deficit hyperactivity disorder (ADHD) have lower cognitive ability and are at risk of adverse educational outcomes; ADHD genetic risks have been found to predict childhood cognitive ability and other neurodevelopmental traits in the general population; thus genetic risks might plausibly also contribute to cognitive ability later in development and to educational underachievement.
Phenotypic Manifestation of Genetic Risk for Schizophrenia During Adolescence in the General Population
Importance Schizophrenia is a highly heritable, polygenic condition characterized by a relatively diverse phenotype and frequent comorbid conditions, such as anxiety and depression. At present, limited evidence explains how genetic risk for schizophrenia is manifest in the general population. Objective To investigate the extent to which genetic risk for schizophrenia is associated with different phenotypes during adolescence in a population-based birth cohort.
