Educational pathways and outcomes for care‐experienced children
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…
Maternal Religiosity and Adolescent Substance Use
Adolescent substance use can have a significant negative impact on life trajectories. Therefore, identifying factors associated with adolescent substance use is important. Previous research has identified parental religiosity as a factor associated with lower adolescent substance use. However, these studies suffered from a number of limitations and are often focussed on US samples, which limit the generalisability of their findings. The present s…
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…
Maternal smoking during pregnancy and offspring risk of intellectual disability
The results are not consistent with a causal effect of maternal smoking during pregnancy on offspring ID
Exploring the associations between adverse childhood experiences (ACEs) and adolescent cancer risk behaviours in the ALSPAC cohort
Childhood adversity was associated with a greater degree of engagement in adolescent cancer risk behaviours. This finding demonstrates the need for targeted primary and secondary prevention interventions that reduce engagement across multiple cancer risk behaviours for children and adolescents who have experienced adversity in childhood, such as parental substance misuse and separation, and reduce exposure to adversity
Prospective relationships between patterns of religious belief/non-belief and mental health in adults
Investigating Change in Student Financial Stress at a UK University
Growing concern for the mental health and wellbeing of higher education students has been linked to increasing financial pressures associated with studying at university, a factor potentially magnified by the recent global pandemic and economic downturn. With limited longitudinal research to date, this study used cross-sectional survey data collected annually at a large UK university (n = 10,876) to examine overall trends in students’ experience …
The effect of parental alcohol use on alcohol use disorder in young adulthood
INTRODUCTION: Parental alcohol use and problems are risk factors for alcohol use disorder (AUD), and these effects may be mediated by adolescent alcohol expectancies and consumption. In the present study, we tested the direct effects of mothers' and fathers' alcohol consumption on young adult AUD, as well as the indirect effects through adolescent maximum alcohol use, alcohol consumption, and alcohol expectancies. METHODS: Participants were 5160 …
Emotional dysregulation in childhood and disordered eating and self‐harm in adolescence
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…
Co‐development of attention deficit hyperactivity disorder and autistic trait trajectories from childhood to early adulthood
BACKGROUND: Attention deficit hyperactivity disorder (ADHD) and autism, defined as traits or disorders, commonly co-occur. Developmental trajectories of ADHD and autistic traits both show heterogeneity in onset and course, but little is known about how symptom trajectories co-develop into adulthood. METHODS: Using data from a population cohort, the Avon Longitudinal Study of Parents and Children, we examined correlations between ADHD and autistic…
Developing and validating a prediction model of adolescent major depressive disorder in the offspring of depressed parents
BACKGROUND: Parental depression is common and is a major risk factor for depression in adolescents. Early identification of adolescents at elevated risk of developing major depressive disorder (MDD) in this group could improve early access to preventive interventions. METHODS: Using longitudinal data from 337 adolescents at high familial risk of depression, we developed a risk prediction model for adolescent MDD. The model was externally validate…
Young People and Intimate Partner Violence
Professionals in all sectors (including schools) need IPVA trauma-informed training that encourages equal power dynamics, with a clear understanding of and access to referral pathways, to be able to respond to the needs of YP experiencing IPVA
Maternal postnatal depressive symptoms and offspring emotional and behavioral development at age 7 years in a U.K. birth cohort
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 …
Suicidal ideation during adolescence
BACKGROUND: Suicidal thoughts and behaviors (STB) constitute a central public health concern in adolescence. Previous studies emphasized the difficulty to cope with negative life events during adolescence as a risk factor for STB. Familial and genetic liability has also been documented to explain STB risk. Nevertheless, less is known about aggregate genetic liability and its possible interaction with negative life events. Moreover, information is…
Being silenced, loneliness and being heard
It is likely that negative labelling and loneliness mediate pathways to IPVA, especially among more disadvantaged young women. The impact of early maltreatment on young people's wellbeing and own relationships is compounded by disadvantage, disability and ethnicity. Participants' resilience was enabled by support in the community
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 …
Is adolescent multiple risk behaviour associated with reduced socioeconomic status in young adulthood and do those with low socioeconomic backgrounds experience greater negative impact? Findings from …
Adolescence appears to be a critical time in the life course to address risk behaviours, due to the likelihood that behaviours established here may have effects in adulthood. Intervening on adolescent MRB could improve later SES outcomes and thus affect health outcomes later in life. Evidence for a moderation effect in the BCS70 but not ALSPAC suggests that more detailed measures should be investigated to capture the nuance of contemporary young …
Adolescent multiple risk behaviours cluster by number of risks rather than distinct risk profiles in the ALSPAC cohort
Clusters of adolescents were not characterised by distinct risk behaviour profiles, and provide no additional insight for intervention strategies. Given this is a more complicated, software-specific method, we conclude that an equally effective, but more readily replicable approach is to use a count of the number of risk behaviours
Alcohol consumption and internalising disorders in young adults of ALSPAC
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…
The proportion of missing data should not be used to guide decisions on multiple imputation
OBJECTIVES: Researchers are concerned whether multiple imputation (MI) or complete case analysis should be used when a large proportion of data are missing. We aimed to provide guidance for drawing conclusions from data with a large proportion of missingness. STUDY DESIGN AND SETTING: Via simulations, we investigated how the proportion of missing data, the fraction of missing information (FMI), and availability of auxiliary variables affected MI …
Predictors of future suicide attempt among adolescents with suicidal thoughts or non-suicidal self-harm
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-suic…
Accounting for missing data in statistical analyses
BACKGROUND: Missing data are unavoidable in epidemiological research, potentially leading to bias and loss of precision. Multiple imputation (MI) is widely advocated as an improvement over complete case analysis (CCA). However, contrary to widespread belief, CCA is preferable to MI in some situations. METHODS: We provide guidance on choice of analysis when data are incomplete. Using causal diagrams to depict missingness mechanisms, we describe wh…
The Independent and Cumulative Effects of Sibling and Peer Bullying in Childhood on Depression, Anxiety, Suicidal Ideation, and Self-Harm in Adulthood
Sibling and peer bullying are reported as the most frequent forms of violence experienced across childhood. There is now ample evidence indicating an association between sibling and peer bullying, with those reporting sibling bullying at an increased risk of peer bullying. While there is convincing evidence of a causative association between peer bullying and a range of mental health outcomes, sibling bullying continues to receive far less attent…
Identifying Critical Points of Trajectories of Depressive Symptoms from Childhood to Young Adulthood
Depression is a common mental illness and research has focused on late childhood and adolescence in an attempt to prevent or reduce later psychopathology and/or social impairments. It is important to establish and study population-averaged trajectories of depressive symptoms across adolescence as this could characterise specific changes in populations and help identify critical points to intervene with treatment. Multilevel growth-curve models we…

Patterns of cannabis use during adolescence and their association with harmful substance use behaviour
BACKGROUND: Evidence on the role of cannabis as a gateway drug is inconsistent. We characterise patterns of cannabis use among UK teenagers aged 13-18 years, and assess their influence on problematic substance use at age 21 years. METHODS: We used longitudinal latent class analysis to derive trajectories of cannabis use from self-report measures in a UK birth cohort. We investigated (1) factors associated with latent class membership and (2) whet…
Testing the impact of local alcohol licencing policies on reported crime rates in England
BACKGROUND: Excessive alcohol use contributes to public nuisance, antisocial behaviour, and domestic, interpersonal and sexual violence. We test whether licencing policies aimed at restricting its spatial and/or temporal availability, including cumulative impact zones, are associated with reductions in alcohol-related crime. METHODS: Reported crimes at English lower tier local authority (LTLA) level were used to calculate the rates of reported cr…
Measurable effects of local alcohol licensing policies on population health in England
BACKGROUND: English alcohol policy is implemented at local government level, leading to variations in how it is put into practice. We evaluated whether differences in the presence or absence of cumulative impact zones and the 'intensity' of licensing enforcement--both aimed at regulating the availability of alcohol and modifying the drinking environment--were associated with harm as measured by alcohol-related hospital admissions. METHODS: Premis…
The Developmental Relationship Between Depressive Symptoms in Adolescence and Harmful Drinking in Emerging Adulthood
Which Behavioral, Emotional and School Problems in Middle-Childhood Predict Early Sexual Behavior
Mental health and school adjustment problems are thought to distinguish early sexual behavior from normative timing (16-18 years), but little is known about how early sexual behavior originates from these problems in middle-childhood. Existing studies do not allow for co-occurring problems, differences in onset and persistence, and there is no information on middle-childhood school adjustment in relationship to early sexual activity. This study e…

Child maltreatment in the “children of the nineties”
Early adolescent substance use and parental socio economic position earlier in life
To examine the association between different indicators of parental socio-economic position (SEP) and a range of substance use in their adolescent offspring. Longitudinal observational study. Population based birth-cohort from the early 90s in the Avon region (ALSPAC, UK). The sample consists of 5837 children (2877 boys and 2960 girls), who attended a face-to-face interview when they were aged 13 (80.5%) or 14. Alcohol consumption without parenta…
Early menarche is associated with an increased risk for depressive symptoms in adolescent girls in a UK cohort
To examine whether girls experiencing earlier menarche than their peers have higher levels of depressive symptoms in adolescence. Longitudinal cohort study. Depressive symptoms were assessed using the Short Mood and Feelings Questionnaire (SMFQ). High levels of depressive symptoms were defined by scores on the SMFQ at or above 11. Age at onset of menarche was derived from regular questionnaires relating to pubertal development completed when the …
Family Pet Ownership during Childhood
In developed nations, approximately half of household environments contain pets. Studies of Human-Animal Interaction (HAI) have proposed that there are health benefits and risks associated with pet ownership. However, accurately demonstrating and understanding these relationships first requires a better knowledge of factors associated with ownership of different pet types. A UK birth cohort, the Avon Longitudinal Study of Parents and Children (AL…
An analysis of the effect of intrauterine growth retardation on spirometric lung function measures of 8-year-old children
Objective Increasing evidence suggests that intrauterine growth retardation (IUGR) is associated with long-term morbidities, including respiratory outcomes. The relationship between IUGR and lung function has been studied in adults, but few studies have investigated childhood respiratory outcomes and it is unclear if catch-up growth in these children influences lung function. We investigated the hypothesis that lung function differs in 8- to 9-ye…

Social Factors Associated with Readiness for Sexual Activity in Adolescents
Dietary patterns by cluster analysis in pregnant women
Little is known about how dietary patterns of mothers and their children track over time. The objectives of this study are to obtain dietary patterns in pregnancy using cluster analysis, to examine women's mean nutrient intakes in each cluster and to compare the dietary patterns of mothers to those of their children. Pregnant women (n = 12 195) from the Avon Longitudinal Study of Parents and Children reported their frequency of consumption of 47 …

Maternal dietary patterns during pregnancy and intelligence quotients in the offspring at 8 years of age
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 clus…
Modelling height in adolescence
Both SITAR or the PBGM are useful models for adolescent growth and provide unbiased estimates of age at peak height velocity. Care should be taken as substantial bias and variance can occur with large measurement error
