O’Driscoll, D.J., Kiely, E., O’Keeffe, L.M., Khashan, A.S.	2023	Poverty trajectories and child and mother wellbeing outcomes in Ireland: findings from an Irish prospective cohort	Open	MedRXiv
Background Poverty is associated with poor outcomes, yet exposure to distinct poverty trajectories in early childhood is not well understood. Objective To understand the prevalence of different trajectories of household poverty and their association with mid-childhood and primary-parent(mother) indicators of physical health and psychopathology in Ireland. Methods We used a nationally representative, prospective cohort (Growing-up-in-Ireland– Infant-Cohort). Household poverty included lowest third income decile, subjective poverty and material deprivation when children were aged 9-months(m),3,5,9-years(y). We used group based multi-trajectory-cluster-modelling to classify trajectories of poverty. Using multivariate logistic regression, adjusted with separate child and mother confounders, we assessed the association of poverty trajectories from 9m to 9y with child outcomes (overweight, any longstanding illness and psychopathology) at age 9y and the same poverty trajectories over the same 9y period with mother outcomes (overweight, any longstanding illness and depression). Results Of 11,134 participants, four trajectories were identified: never-in-poverty (43.1%), material/subjective>monetary-poverty (16.1%), monetary>material-poverty (25.6%), and persistent-poverty (15.2%). Children in persistent-poverty compared with never in poverty experienced higher odds of being overweight at 9y (adjusted odds ratio aOR 1.70,95% CI 1.34, 2.16), having a longstanding illness (aOR 1.51,95% CI 1.20, 1.91) and psychopathology (aOR 2.06,95% CI 1.42, 2.99). The outcomes for primary parent (99.7% were mothers) had higher odds of being overweight (aOR 1.49,95% CI 1.16, 1.92), having a longstanding illness (aOR 2.13,95% CI 1.63, 2.79), and depression (aOR 3.54,95% CI 2.54, 4.94). Conclusions Any poverty trajectory was associated with poorer psychopathology and physical wellbeing in late childhood for children and their mothers in Ireland. What is already known on this subject? Poverty is understood as having both objective (e.g. low household income) and subjective dimensions (e.g., perception of being poor relative to others, poverty related anxiety). Evidence highlights the association between child poverty exposure and child and mother wellbeing outcomes. What this study adds? Our study examined predicted trajectories of multi-dimensional poverty and child and mother outcomes using a large national cohort. We identified that any poverty trajectory in childhood had a higher odds of being associated with poor well-being outcomes. How this study might affect research, practice or policy? This study highlights the need for strategies to ameliorate any poverty exposure as all poverty trajectories resulted in poorer wellbeing outcomes. Strategies should be considered to ameliorate any poverty exposure in early childhood (e.g., school based resourcing).
Bowe, A.K., Lightbody, G., O’Boyle, D.S., Staines, A., Murray, D.M.	2024	Predicting low cognitive ability at age 5 years using perinatal data and machine learning	Open	Pediatric Research
Background There are no early, accurate, scalable methods for identifying infants at high risk of poor cognitive outcomes in childhood. We aim to develop an explainable predictive model, using machine learning and population-based cohort data, for this purpose. Methods Data were from 8858 participants in the Growing Up in Ireland cohort, a nationally representative study of infants and their primary caregivers (PCGs). Maternal, infant, and socioeconomic characteristics were collected at 9-months and cognitive ability measured at age 5 years. Data preprocessing, synthetic minority oversampling, and feature selection were performed prior to training a variety of machine learning models using ten-fold cross validated grid search to tune hyperparameters. Final models were tested on an unseen test set. Results A random forest (RF) model containing 15 participant-reported features in the first year of infant life, achieved an area under the receiver operating characteristic curve (AUROC) of 0.77 for predicting low cognitive ability at age 5. This model could detect 72% of infants with low cognitive ability, with a specificity of 66%. Conclusions Model performance would need to be improved before consideration as a population-level screening tool. However, this is a first step towards early, individual, risk stratification to allow targeted childhood screening. Impact • This study is among the first to investigate whether machine learning methods can be used at a population-level to predict which infants are at high risk of low cognitive ability in childhood. • A random forest model using 15 features which could be easily collected in the perinatal period achieved an AUROC of 0.77 for predicting low cognitive ability. • Improved predictive performance would be required to implement this model at a population level but this may be a first step towards early, individual, risk stratification.
Butler, E., Clarke, M., Spirtos, M., O Keeffe, L.M., Dooley, N.	2024	Pregnancy complications and childhood mental health: is the association modified by sex or adverse social circumstances? Findings from the ‘growing up in Ireland’ national infant cohort study	Open	Social Psychiatry and Psychiatric Epidemiology
Specific pregnancy complications, socioeconomic position and sex have all been independently associated with child mental health outcomes, but their combined effects remain unclear. We examined whether total number of complications experienced in the pregnancy associated with mental health at 5 and 9-years, and whether this varied by sex or adverse social circumstances. Pregnancy complications were self-reported at 9-months post-natally from a list of 16 complications. Parents completed the Strengths and Difficulties Questionnaire (SDQ) when their child was 5 and 9-years. The primary outcome was the SDQ-total and scoring in the clinical range (> 16) was a secondary outcome. We applied generalized linear mixed models to a large nationally representative Irish cohort (GUI; n = 11,134). Analyses were adjusted for sex, adverse social circumstances (at 9-months), and gestational smoking. We included an interaction term between pregnancy complications and each variable respectively in separate models to examine if associations varied by sex or adverse circumstances. After controlling for covariates, total complications associated with mental health at 5 and 9-years. Each additional pregnancy complication conferred a 10% higher total-SDQ score (exponentiated co-efficient 1.10 [95%CI 1.06–1.14], 1.20 [1.15–1.26], 1.20 [1.12–1.29] and 1.34 [1.21–1.48] for 1, 2, 3 and 4 + complications respectively). For the dichotomised outcome, generally increasing odds for clinical levels of mental health difficulties were observed (OR 1complication = 1.89, 95%CI [1.37–2.59]; OR 2complications = 2.31, 95%CI [1.53–3.50]; OR 3complications = 1.77, 95%CI [0.89–3.52]; OR 4 + complications = 6.88, 95%CI [3.29–14.40]). Females had significantly lower odds of exhibiting clinically significant mental health difficulties than males (OR = 0.43, 95%CI[0.32–0.57]). There was no evidence that the association between pregnancy complications and child’s mental health varied by sex or social circumstances at 5 or 9-years. Males exposed to numerous pregnancy complications in the context of adverse social circumstances had the highest predicted probability of having mental health difficulties in middle childhood.
O'Keeffe, L.M., Kearney, P.M., Greene, R.A.	2015	Pregnancy Risk Assessment Monitoring System in Ireland: Methods and Response Rates	Open	Maternal and Child Health Journal
To describe response rates and characteristics associated with response to the Pregnancy Risk Assessment Monitoring System study in Ireland (PRAMS Ireland). Using hospital discharge records of live births at a large, urban, obstetric hospital, a sampling frame of approximately 2,400 mother-infant pairs were used to alternately sample 1,200 women. Mothers’ information including name, address, parity, age and infant characteristics such as sex and gestational age at delivery were extracted from records. Modes of contact included an invitation letter with option to opt out of the study, three mail surveys, a reminder letter and text message reminder for remaining non-respondents. Sixty-one per cent of women responded to the PRAMS Ireland survey over a 133 day response period. Women aged <30, single women, multiparous women and women with a preterm delivery were less likely to respond. Women participating in PRAMS Ireland were similar to the national birth profile in 2011 which had a mean age of 32, were 40 % primiparous, 33 % single or never married and had a 28 % caesarean section rate. Survey and protocol changes are required to increase response rates above recommended Centers for Disease Control and Prevention (CDC) thresholds of 65 % within the recommended 90 day data collection cycle. Additional efforts such as stratification and over-sampling are required to increase representativeness among hard to reach groups such as younger, single and multiparous women before expanding the project to an ongoing, national surveillance system in Ireland.
McCrory, C., Layte, R.	2012	Prenatal exposure to maternal smoking and childhood behavioural problems: a quasi-experimental approach.	Open	Journal of Abnormal Child Psychology
This retrospective cross-sectional paper examines the relationship between maternal smoking during pregnancy and children’s behavioural problems at 9 years of age independent of a wide range of possible confounders. The final sample comprised 7,505 nine-year-old school children participating in the first wave of the Growing Up in Ireland study. The children were selected through the Irish national school system using a 2-stage sampling method and were representative of the nine-year population. Information on maternal smoking during pregnancy was obtained retrospectively at 9 years of age via parental recall and children’s behavioural problems were assessed using the Strengths and Difficulties Questionnaire across separate parent and teacher-report instruments. A quasi-experimental approach using propensity score matching was used to create treatment (smoking) and control (non-smoking) groups which did not differ significantly in their propensity to smoke in terms of 16 observed characteristics. After matching on the propensity score, children whose mothers smoked during pregnancy were 3.5 % (p < 0.001) and 3.4 % (p < 0.001) more likely to score in the problematic range on the SDQ total difficulties index according to parent and teacher-report respectively. Maternal smoking during pregnancy was more strongly associated with externalising than internalising behavioural problems. Analysis of the dose–response relationship showed that the differential between matched treatment and control groups increased with level of maternal smoking. Given that smoking is a modifiable risk factor, the promotion of successful cessation in pregnancy may prevent potentially adverse long-term consequences.
Brannigan, R., Healy, C., Cannon, M., Leacy, F. P., Clarke, M. C.	2020	Prenatal tobacco exposure and psychiatric outcomes in adolescence: is the effect mediated through birth weight?	Open	Acta Psychiatrica Scandinavia
Objective This study aims to examine the associations between prenatal exposure to maternal smoking, birth weight and persistent offspring psychiatric symptoms. Additionally, we aim to examine whether the relationship between prenatal maternal smoking and persistent offspring psychiatric symptoms is mediated by offspring birth weight. Methods This study used the Growing Up in Ireland (GUI) longitudinal cohort. The GUI is a nationally representative longitudinal study of children which consisted of three data collection waves, at ages 9, 13, and 17 years. Logistic regression analysis was used to examine associations between prenatal tobacco exposure, and offspring psychiatric symptoms. Linear regression was used to examine associations between prenatal tobacco exposure and offspring birth weight. We conducted a mediation analysis examining potential etiological pathways linking maternal smoking during pregnancy, offspring birth weight, and later offspring psychiatric symptoms. All analyses were adjusted for confounders including household income, maternal level of education, and family psychiatric history. Additionally, examination of birth weight and subsequent psychiatric symptoms also was controlled for prematurity. Results We found that the association between prenatal tobacco exposure and later psychiatric symptoms is mediated by birth weight. Conclusions This work provides further evidence that maternal smoking during pregnancy is an important modifiable lifestyle factor that has an impact not just on the physical health of offspring but also their mental wellbeing. Supporting women with structured smoking cessation programs at the earliest stages of pregnancy should be a public health priority.
Coughlan, S., Quigley, J., Nixon, E.	2023	Preterm birth and expressive language development across the first 5 years of life: A nationally-representative longitudinal path analysis	Open	Early Childhood Research Quarterly
Multiple factors including the child’s non-linguistic characteristics and caregiving environment can affect language development. Since preterm birth (<37 weeks’ gestation) can negatively affect language development, this study used path analysis to investigate whether the influence of preterm birth on expressive language development at 3 and 5 years of age is mediated by a child’s non-linguistic characteristics (temperament and cognitive, motor, and social-personal abilities), caregiving environment (maternal and paternal stress and depression, mother-child and father-child relationship quality), and interactions between these domains. These analyses were conducted using three waves of data (ages: 9 months, 3 years, 5 years) on 8,712 children (4,300 female; 535 preterm) from a nationally-representative longitudinal study in Ireland. Preterm birth was indirectly (but not directly) associated with expressive language at 3 years of age via cognitive and social-personal abilities (but not motor abilities, mother-child relationship quality, or father-child relationship quality) at 9 months. There was no direct or indirect effect of preterm birth on expressive language at 5 years of age. Preterm birth negatively affected mother-child and father-child relationship quality at 3 years via fussy-difficult temperament and mother’s/father’s stress (but not depression) at 9 months. These findings are discussed with reference to international standards for neonatal care, including the need for long-term developmental monitoring of children born preterm by multidisciplinary healthcare teams, alongside parental supports promoting mental health and confidence in caregiving tasks. Future study recommendations are made to expand the tested models in line with family systems perspectives.
McNally, S., Share, M., Murray, A.	2014	Prevalence and predictors of grandparent childcare in Ireland: Findings from a nationally representative sample of infants and their families.	Open	Child Care in Practice
Anecdotal evidence suggests that grandparents provide a substantial amount of childcare support to parents of infants in Ireland yet there has been little attention to the provision of grandparent childcare at policy level. Using nationally representative data on childcare provision in the Republic of Ireland, this study examined the prevalence of grandparent childcare provision for very young children, and associations between this choice of childcare and key infant, family, and community factors. Using archived data from the Infant Cohort of the Growing Up in Ireland study, descriptive data regarding use of grandparents as childcare providers were outlined. A series of bivariate analyses were then conducted to examine the independent association between a range of infant, family, and community variables and use of grandparent childcare. Finally, a multivariate analysis using binomial logistic regression was used to examine the association of each of these variables in a fully adjusted model. The results show that 38.6% of infants experienced non-parental childcare: 12.4% were looked after by grandparents, 15.7% by other home-based carers and 10.5% in childcare centres such as crèches. Grandparents were the cheapest source of childcare but also provided fewer hours on average. Multivariate analysis indicated the importance of parental income, age, and education in choosing grandparental childcare, with younger, less well-off parents using grandparent childcare more than any other type of childcare. The findings suggest that, whether by choice or by economic pressure, grandparents represent a huge resource in terms of providing childcare for infants. Current childcare policy needs to be cognisant of the significant contribution of grandparents in helping families with young children participate in the labour force. Constraints on the amount of care grandparents are able to provide may have knock-on constraints for parents’ participation in the labour force and earnings.

Darmody, M., Smyth, E.	2016	Primary School Principals' Job Satisfaction and Occupational Stress	Open	International Journal of Educational Management
Purpose The purpose of this paper is to explore the factors associated with occupational stress and job satisfaction among Irish primary school principals. A principal’s job has become increasingly demanding and complex in recent decades. However, there is little current research into their levels of stress and job satisfaction, particularly based on nationally representative data. In order to understand how principals perceive their job and how best to support them, new insights into factors contributing to job satisfaction and stress of school principals are warranted. Design/methodology/approach The paper draws on an analysis of Growing up in Ireland data, a national representative study of nine-year-old children in Ireland. In order to explore the simultaneous impact of individual and school factors on stress and job satisfaction of principals in Irish primary schools, multivariate analysis was used. Analyses in this paper are based on responses from principals in 898 schools. Findings The results of the study indicate that a significant number of primary school principals in Ireland are not very satisfied and feel stressed about their job. Regression analysis revealed that job satisfaction and occupational stress were related to a complex set of personal characteristics, working conditions, school context and teacher climate. Research limitations/implications The data are limited to primary school principals. However, this is in itself an advantage since it allows for greater insights into variation across principals in job satisfaction and stress, holding the effect of school level constant. Originality/value This is the first study of its kind in the Irish context that explores the simultaneous effect of a number of factors on school principals’ stress and job satisfaction.

Darmody, M., Smyth, E.	2017	Profile of second-level students exempt from studying Irish	Open	ESRI Working Paper No.527
Drawing on curriculum differentiation theory, this paper discusses exemptions from learning Irish granted to Irish post-primary students. In order to explore the profile of students granted such exemptions, the study utilises data from a national longitudinal study, Growing Up in Ireland. Additional information is provided by administrative data collected by the Department of Education and Skills to show trends in the number of exemptions granted over time. The findings show that factors impacting on being exempt include gender, social class, having a special educational need at primary school and being born outside Ireland.

Sharma, V., Cassetti, O., Winning, L., O’Sullivan, M., Crowe, M.	2023	Protocol for developing a dashboard for interactive cohort analysis of oral health-related data	Open	BMC Oral Health
Introduction: A working knowledge of data analytics is becoming increasingly important in the digital health era. Interactive dashboards are a useful, accessible format for presenting and disseminating health-related information to a wide audience. However, many oral health researchers receive minimal data visualisation and programming skills. Objectives: The objective of this protocols paper is to demonstrate the development of an analytical, interactive dashboard, using oral health-related data from multiple national cohort surveys. Methods: The flexdashboard package was used within the R Studio framework to create the structure-elements of the dashboard and interactivity was added with the Shiny package. Data sources derived from the national longitudinal study of children in Ireland and the national children’s food survey. Variables for input were selected based on their known associations with oral health. The data were aggregated using tidyverse packages such as dplyr and summarised using ggplot2 and kableExtra with specific functions created to generate bar-plots and tables. Results: The dashboard layout is structured by the YAML (YAML Ain’t Markup Language) metadata in the R Markdown document and the syntax from Flexdashboard. Survey type, wave of survey and variable selector were set as filter options. Shiny’s render functions were used to change input to automatically render code and update output. The deployed dashboard is openly accessible at https://dduh.shinyapps.io/dduh/. Examples of how to interact with the dashboard for selected oral health variables are illustrated. Conclusion: Visualisation of national child cohort data in an interactive dashboard allows viewers to dynamically explore oral health data without requiring multiple plots and tables and sharing of extensive documentation. Dashboard development requires minimal non-standard R coding and can be quickly created with open-source software.
Okolikj, M., Girard, L.	2023	Psychological Antecedents of Political Outcomes: Joint Developmental Trajectories of Mental Health Difficulties	Open	SocArXiv Papers
Little is known about the link between childhood and adolescent mental health (MH) difficulties and political outcomes in adulthood. This represents an important knowledge gap in understanding early individual-level factors for future political outcomes. Using the Growing up in Ireland cohort, following 8,568 children from nine to 20 years, we examine how different MH difficulties, and co-occurrence, are associated with various political outcomes. The results show childhood/adolescent MH difficulties are important predictors of political outcomes at age 20. Adolescents with chronic co-occurring MH difficulties starting in childhood report a lower interest in politics, lower trust in politicians, are less likely to register to vote, and if voting, are more likely to vote for an anti-establishment party. Adolescents with chronic emotional MH difficulties starting in childhood report a higher likelihood of voting for an anti-establishment party, but also show a higher probability of political activism and low external political efficacy.
Cotter, S., Healy, C., Ní Cathain, D., Williams, P., Clarke, M., Cannon, M.	2019	Psychopathology and early life stress in migrant youths: an analysis of the 'Growing Up in Ireland' study	Open	Irish Journal of Psychological Medicine
Objectives Migrant youths endure many challenges. Such challenges can be stressful and lead to psychological difficulties. We investigated the relationship between migration, psychopathology and stressful events in children and adolescents. We hypothesised that migrant youths would show higher levels of psychopathology and more stressful life events than non-migrant youths. Method Using the Child cohort (Cohort ‘98) of the ‘Growing up in Ireland’ study we investigated psychopathology, as measured by the Strengths and Difficulties questionnaire (SDQ) at age 9 and 13 and stressful life events in migrant and non-migrant youths. Results There was no significant difference between the proportion of migrant and non-migrant youths reporting psychopathology in childhood (p>0.05) or adolescence (p>0.05). Analysis of the SDQ subscales revealed that a significantly greater proportion of migrant youths had hyperactivity problems in childhood (p = 0.04) but a greater proportion of non-migrant youths had emotional problems in early adolescence (p = 0.04). We found that migrant youths experienced significantly more stressful life events than their non-migrant counterparts (p<0.01), however, once ‘Moving house/country‘ was removed as a stressor, there was no difference between the groups (p>0.27). Conclusions Contrary to our hypothesis, we observed that there were few differences between migrant and non-migrant youths in the levels of psychopathology. Migrant youths experienced a greater number of stressful life events, however, this was attributable to stressors relating to moving. An increased understanding of the factors promoting resilience, as demonstrated by the migrant youths, could aid health professionals and policy makers to effectively tailor interventions for mental health promotion.

McGuire, F., Reynolds, C., Codd, M.	2023	Quarantweens - the impact of COVID-19 restrictions on preteen health and wellbeing in Ireland	Open	European Journal of Public Health
Background The COVID-19 pandemic has been dubbed the “biggest public health crisis since the Second World War”. In Ireland, schools were closed for 141 days, dramatically altering the day to day lives of children in Ireland. This research aimed to evaluate the overall wellbeing of schoolchildren in Ireland and capture the prevalence and factors contributing to poor mental health. Methods A cross-sectional study was performed based on data from the Growing Up in Ireland COVID-19 web survey of the ’08 Infant cohort. Mental Health Inventory-5 scores were used to assess children at risk of mental health disorders. Logistic regression examined associations between various demographic and psychosocial factors and risk of mental health disorders. Results This study included 2,867 primary caregiver- child dyads. Almost 25% of 12/13-year-olds were at risk of mental health disorders (MHDs). An adjusted logistic regression model found associations between being at higher risk of MHDs and factors such as reduced physical activity levels (OR 1.35, 95% CI 1.10-1.66), spending less time outdoors (OR 1.48, 95% CI 1.18-1.85), increased screen-time (OR 1.35, 95% CI 1.09-1.67) and increased arguments with PCGs (OR 3.44, 95% CI 2.78-4.27). Having a trusted adult confidante reduced the risk of MHD (OR 0.25, 95% CI 0.14-0.45). Conclusions The prevalence of 12/13-year olds at elevated risk of MHD was high, indicating an urgent need for enhancement of child and adolescent mental health services in Ireland. Physical activity, time outdoors and supportive relationships with primary caregivers were positively associated with reduced MHD risk. Key messages Children were impacted by the COVID-19 restriction measures in a way that was disproportionate to their risk. To reduce the risk of poor mental health outcomes for a generation of “quarantweens” we need to place children front-andcentre of our response as we recover from COVID-19.
Healy, S., Patterson, F., Williams, E., Lozano, A.J., Hanlon, A., Obrusnikova, I.	2020	Rethinking daily movement behaviours of children with autism spectrum disorder: meeting the 24-hour movement guidelines	Open	European Journal of Adapted Physical Activity
In an effort to promote optimal health in all children, 24-hour movement guidelines that provide specific recommendations for physical activity, screen-time, and sleep have been developed (≥ 1 hour of physical activity, ≤ 2 hours of screen-time, 9-11 hours of sleep). Children who meet the recommendations for these health behaviours are less likely to be obese than those who do not meet them. This study compared the degree to which children with autism spectrum disorder (ASD) and typically developing (TD) children met the newly developed 24-hour movement guidelines. A propensity-score matched sample of 72 children (36 children with ASD, 36 TD children) from the “Growing Up in Ireland” study was included in the analysis. Based on parents’ completion of time-use diaries, fewer children with ASD, compared to TD children, met the recommendations for screentime (58.3% vs. 80.6%, p=0.07, V=0.24) and physical activity (41.7% vs. 69.4%, p=0.03, V=0.28). Children with ASD were most likely to meet two guidelines (44.4%), whereas TD children most commonly met all three guidelines (55.6%). The findings highlight the breadth of health behaviours that require intervention among children with ASD. The current study suggests that examining the movement behaviours that constitute a 24-hour period for children with ASD may be useful to inform interventions to reduce their risk for sub-optimal health.

Ó Donnchadha, S., Bramham, J., Greene, C.	2020	Rethinking the association between overweight/obesity and ADHD in children: a longitudinal and psychosocial perspective	Open	Irish Journal of Psychological Medicine
Objective This study examines the association between attention-deficit/hyperactivity disorder (ADHD) and overweight/obesity in a large-scale longitudinal study of children, while controlling for a range of psychosocial factors. Method Data were obtained from Growing Up in Ireland, a nationally representative and longitudinal study of approximately 6500 children who were assessed at 9 and 13 years of age. Body mass index (BMI) was determined using measured height and weight, ADHD status was determined by parent reports of professional diagnoses and ADHD symptoms were measured using the Strengths and Difficulties Questionnaire (SDQ). Results The associations between ADHD status, ADHD symptoms (SDQ) and BMI category at age 9 and 13 years were evaluated using logistic regression. Adjustments were made for child factors (sex, developmental coordination disorder, emotional symptoms, conduct problems, birth weight and exercise) and parental factors (socio-economic status, parental BMI, parental depression, and maternal smoking and alcohol use during pregnancy). Logistic regression indicated that ADHD status was not associated with BMI category at 9 or at 13 years of age, but children with ADHD at 9 years were significantly more likely to be overweight/obese at 13 years than those without ADHD. However, when other child and parental factors were adjusted for, ADHD status was no longer significantly associated with weight status. Female sex, low levels of exercise, overweight/obese parents and prenatal smoking during pregnancy consistently increased the odds of childhood overweight/obesity. Conclusions While ADHD and overweight/obesity co-occur in general populations, this relationship is largely explained by a variety of psychosocial factors.

Smyth, E., Darmody, M.	2021	Risk and protective factors in adolescent behaviour: The role of family, school and neighbourhood characteristics in (mis)behaviour among young people	Open	ESRI Research Series 119
This report uses data collected on Cohort ’98 of the Growing Up in Ireland (GUI) study at 9, 13 and 171 years of age to examine the individual, family, peer, school and neighbourhood factors associated with adolescent behaviour patterns. The study adopts a multidimensional approach and draws on multiple informants, looking at six types of behaviour. Externalising behaviour relates to conduct (‘acting out’) and concentration difficulties. Internalising behaviour relates to negativity directed towards the self (i.e. mood or emotional difficulties) and difficulties interacting with peers, while prosocial behaviour is an indicator of positive development, reflecting positive interaction with others. All three are measured using the Strengths and Difficulties Questionnaire (SDQ), are based on reports from the primary caregiver (usually, the mother2) and are therefore likely to capture behaviour within the family or home context. Behaviour at school is captured using information on school-based misbehaviour (such as ‘messing’ in class) and on truancy, reported by the young person themselves. Antisocial behaviour, also based on the young person’s report, reflects behaviour in the wider community (such as graffiti or damaging property). The study addresses the following research questions: 1. What patterns of (mis)behaviour are found among young people at 9, 13 and 17 years of age? To what extent do these patterns relate to differences in family resources, namely, social class, parental education and household income? 2. To what extent does adolescent behaviour reflect the social mix of the school, over and above the effects of individual family background (including parental education, income and social class)? 3. To what extent does adolescent behaviour reflect the social composition of the neighbourhood, over and above the effects of individual family background? 4. What family, peer, school and neighbourhood factors help to reduce the incidence of behaviour difficulties among young people?
McCoy, S., Banks, J., Shevlin, M.	2012	School matters: How context influences the identification of different types of special educational needs	Open	Irish Educational Studies
Despite dramatic changes in Irish special education policy during the last decade, there is little understanding of the factors influencing how special educational needs (SEN) are identified and whether identification varies across different school contexts. International research has tended to focus on how individual child characteristics influence SEN identification. Less attention has been given to other factors such as teacher characteristics or school social mix. Using data from the nine-year-old cohort of the Growing Up in Ireland study, this article examines which children are most likely to be identified with different SEN types taking into account student social background characteristics, teacher characteristics and school social mix. Findings show that children attending highly disadvantaged school contexts are far more likely to be identified with behavioural problems and less likely to be identified with learning disabilities than children with similar characteristics attending other schools. It seems that ‘behavioural’ issues take precedence over learning difficulties in these schools pointing to a culture of care/containment rather than academic progress.

Lane, A., Harrison, M., Murphy, N.	2014	Screen time increases risk of overweight and obesity in active and inactive 9 year old Irish children: a cross sectional analysis	Open	Journal of Physical Activity and Health
Background Independent associations between screen time (ST)/physical activity (PA) and overweight (OW)/obesity have been demonstrated but little research exists on the role of ST among sufficiently active children. Purpose To examine the combined influence of ST and PA on risk of OW/obesity in a nationally representative sample of 9-year-old Irish children. Methods The sample in this cross sectional analysis contained 8568 children. Self-report parent data were used to group children into ST and PA categories and related to OW/obesity using forced entry logistic regression. Results High ST (> 3 hours/day), bedroom TV and mobile phone ownership increased risk of OW/obesity in high and low active children (P < .05). Low PA (<9 bouts fortnightly) was also associated with OW/obesity. In combined analyses, OW/obesity was lowest in the reference low ST/high PA group with ORs of 1.38, 1.63, and 2.07, respectively, in the low ST/low PA, high ST/high PA, and high ST/low PA groups. Access to electronic media, low socioeconomic status, parental obesity, and not engaging in sports were all related to high ST (P < .05). Conclusion This study supports findings that ST is associated with OW/Obesity demonstrating this separately in high and low active children.
