The incidence of adiposity in the early years of life has outgrown the prevalence in older children and adolescents globally; however, the factors influencing weight gain are predominantly studied in adults. This study examines the relationship between changing economic conditions during the Irish recession and child weight in a nationally representative sample of 10,011 Irish children studied at 9 months, 3 years and 5 years old. This study is the first to use longitudinal anthropometric measurements to estimate the impact of direct parental unemployment on children’s weight. Fixed effect logistic regression is used to examine the effects of parental unemployment on weight using the Growing up in Ireland infant cohort from 2008 to 2013. Weight and length/height measured by trained interviewers and child growth charts are used to quantify children’s weight status according to BMI-for-age and weight-for-age measures. For BMI-for-age, the probability of a child being classified as overweight/obese is 8 percentage points higher if either parent experiences unemployment. A sensitivity analysis of weight-for-age indicates that the probability is of similar magnitude across several alternative growth charts and definitions of adiposity (the WHO standard, British Growth Reference, and Centers for Disease Control). The analysis is repeated, cross-sectionally, for physical activity and diet to clarify mechanisms of effect. The probability of a child consuming healthy food and physical activity with an implied cost is lower if either parent becomes unemployed. A focus on overweight/obesity in the early years is of crucial importance as if current trends are not addressed, a generation of children may grow up with a higher level of chronic disease.

The increasing emphasis on inclusive education internationally has broadened the definition of special educational needs (SEN) and greatly affected national prevalence estimates. In line with these international trends, in Ireland the EPSEN Act (2004) defines SEN as any “restriction in the capacity of a person to participate in or benefit from education”. Taking this broad definition, this study draws on the first longitudinal study of children in Ireland, Growing Up in Ireland, to generate a new estimate of SEN prevalence among Irish nine-year-old children. The analysis combines detailed information, collected from parents and teachers, encompassing diverse types of SEN, including physical disabilities, speech impairments, learning disabilities and emotional/behavioural difficulties. In doing so, the study establishes a SEN prevalence rate of 25 per cent among children in the mid-primary years, a rate very much in line with recent research in other European contexts. Additionally, the study details the diversity of data collected on children and young people with SEN and disabilities across agencies and government departments, the potential value of this data and directions for improved learner databases.

The increasing importance of identifying lesbian, gay, bisexual and transgender (LGBT+) populations is a key driver in changes to demographic data collection in representative surveys of youth. While such population-based data are rare, Growing Up in Ireland (GUI), an Irish, government-funded, longitudinal survey, includes sexual orientation and gender identity (SOGI) measurements. This qualitative study responds to a query from the GUI study team and aims to identify how best to collect SOGI data in future waves of GUI. A university Human Research Ethics Committee granted approval for online consultations with LGBT+ youth (n = 6) with experiential expertise in policy making. The research is underpinned by rights-based public patient involvement (PPI) with recorded discussions, which were transcribed and imported into NVivo 12, generating the theme “recognition in research, policy and society”. This co-created article, with the LGBT+ young PPI Panel members, commends the inclusion of SOGI data in GUI and recommends changes in question placement and phrasing. Aligning with best practice, the PPI members provide a template for wording on consecutive sex and gender questions, expanded sexual orientation identity categories and maintaining the existing well-phrased transgender question from GUI. This offers potential to improve the quality of the SOGI data collected and the experience of those completing the questionnaire. These findings extend beyond GUI, with relevance for surveys with youth populations. This paper underscores the potential and benefits of participatory approaches to research with youth and views their role beyond simply as sources of data.

The internet provides opportunities for social interactions which first occur in an online environment that can lead to meeting up in real life. However, growing concerns around safety and privacy warrant greater study of this modern-day phenomenon. Using a longitudinal dataset of approximately 4,300 20-year-olds in Ireland, this study finds one-in-three report meeting someone from online. Multiple regression reveals that females are less likely to engage in such behaviour, while the trait of ‘openness’, spending more time on the internet, being non-heterosexual, using dating apps, and being sexually active at 17 years are positively associated. Early exposure to information and communication technologies, as indicated by mobile phone ownership at 9 years, is also associated with online-to-offline encounters. A range of policy considerations are discussed, including the continued need for education in e-safety and cyber safety awareness from a young age through young adulthood, particularly for groups such as LGBT communities.

The Irish education system is undergoing significant change as it navigates the challenges of the 2020s. Schools are at the frontline of Ireland’s efforts to integrate migrant families, build an inclusive society and tackle generational socioeconomic inequality. They are also, increasingly, key sites of contestation over deep social questions like the place of faith and secularism in public institutions and the best path to ensuring young people thrive, regardless of their gender or sexual orientation. While many of these challenges resonate across the second-level sector as all schools grapple with the difficulties and opportunities of educating young adults in today’s Ireland, the focus of this report is on the voluntary secondary school sector. The report presents rich evidence from a mixed-method research study across 21 voluntary secondary schools. The research was commissioned by the Joint Managerial Body for Voluntary Secondary Schools (JMB), with the research questions designed to examine the features and experiences of students, teachers and school leaders across the voluntary sector. However, the study allows for comparisons between experiences in voluntary secondary schools and other sectors. In particular, the survey of students undertaken in this study is compared to the nationally representative longitudinal study Growing Up in Ireland (GUI) and the International Student Assessment (PISA study) on 15 year olds in Ireland and across the European Union (EU). This approach allows for a deep exploration of the voluntary secondary sector, while also placing experiences in a national and international context.

The microbiome-gut-brain axis plays a role in anxiety, the stress response and social development, and is of growing interest in neuropsychiatric conditions. The gut microbiota shows compositional alterations in a variety of psychiatric disorders including depression, generalised anxiety disorder (GAD), autism spectrum disorder (ASD) and schizophrenia but studies investigating the gut microbiome in social anxiety disorder (SAD) are very limited. Using whole-genome shotgun analysis of 49 faecal samples (31 cases and 18 sex- and age-matched controls), we analysed compositional and functional differences in the gut microbiome of patients with SAD in comparison to healthy controls. Overall microbiota composition, as measured by beta-diversity, was found to be different between the SAD and control groups and several taxonomic differences were seen at a genus- and species-level. The relative abundance of the genera Anaeromassillibacillus and Gordonibacter were elevated in SAD, while Parasuterella was enriched in healthy controls. At a species-level, Anaeromassilibacillus sp An250 was found to be more abundant in SAD patients while Parasutterella excrementihominis was higher in controls. No differences were seen in alpha diversity. In relation to functional differences, the gut metabolic module ‘aspartate degradation I’ was elevated in SAD patients. In conclusion, the gut microbiome of patients with SAD differs in composition and function to that of healthy controls. Larger, longitudinal studies are warranted to validate these preliminary results and explore the clinical implications of these microbiome changes.

The notion that digital-screen engagement decreases adolescent well-being has become a recurring feature in public, political, and scientific conversation. The current level of psychological evidence, however, is far removed from the certainty voiced by many commentators. There is little clear-cut evidence that screen time decreases adolescent well-being, and most psychological results are based on single-country, exploratory studies that rely on inaccurate but popular self-report measures of digital-screen engagement. In this study, which encompassed three nationally representative large-scale data sets from Ireland, the United States, and the United Kingdom (N = 17,247 after data exclusions) and included time-use-diary measures of digital-screen engagement, we used both exploratory and confirmatory study designs to introduce methodological and analytical improvements to a growing psychological research area. We found little evidence for substantial negative associations between digital-screen engagement—measured throughout the day or particularly before bedtime—and adolescent well-being.

The objective of this paper is to quantify and decompose the socioeconomic gradient in childhood obesity in the Republic of Ireland. The analysis is performed using data from the first wave of the Growing Up in Ireland survey, a nationally representative survey of 8568 nine-year-old children conducted in 2007 and 2008. We estimate concentration indices to quantify the extent of the socioeconomic gradient in childhood obesity and undertake a subsequent decomposition analysis to pinpoint the key factors underpinning the observed inequalities. Overall the results confirm a strong socioeconomic gradient in childhood obesity in the Republic of Ireland. Concentration indices of obesity (CI = −0.168) and overweight/obese (CI = −0.057) show that the gradient is more pronounced in obese children, while results from the decomposition analysis suggest that the majority of the inequality in childhood obesity is explained by parental level variables. Our findings suggest that addressing childhood obesity inequalities requires coordinated policy responses at both the child and parental level.

The objective of this study was to explore the extent to which the association between screen time and psychosocial development in preschool children differed between the sexes and according to their frequency of engagement in physical activity. Data are based on a prospective cohort of Irish children, collected between 2010 and 2013 when children were ages 3 (n=9786) and 5 years (n=9001). Children’s screen time (h/day), psychosocial development (Strengths and Difficulties Questionnaire), and physical activity (bouts/week) were assessed via caregiver report. The magnitude of the association between screen time and changes in behavioural difficulties differed significantly between the sexes. For boys, the association between increased screen time and the onset of behavioural problems coincided directly with a reduction in their frequency of engagement in physical activity. The association between screen time and changes in behavioural difficulties was not moderated by girls’ engagement in physical activity, however; and there was no difference in the association between screen time and prosocial behaviours at different frequencies of engagement in physical activity for either boys or girls.

Conclusions
Results support recommendations to establish greater balance between physical activity and sedentary behaviours in token economy systems to minimise the negative effects of excessive screen time.

The objective was to identify determinants of uptake and maintenance of active school travel (AST) over 4 years in children aged 9 at baseline. Data from wave 1 (n=8502) and 2 (n=7479) of the Growing Up in Ireland study were analysed. At 9- and 13-years 25% and 20% engaged in AST. Children were more likely to maintain or take-up AST if they lived in an urban area. Change in distance to school influenced both maintenance and adoption of AST, with a negative impact seen for increased distance between 9 and 13 years and a positive impact seen for decreased distance. Some factors which predict uptake and maintenance of AST are modifiable and can inform intervention development.

The paper examines the effects of socioeconomic background (SES) – measured by social class, family income and parental education – cognitive ability, and gender on a variety of key outcomes from a large longitudinal study based on a representative sample of thirteen-year-olds. The data analysed comprised 6216 children who participated in waves 1 to 3 of the Growing Up in Ireland (GUI) longitudinal survey. The outcome measures drawn from wave 3, when respondents were aged about seventeen, were: examination results and several cognitive measures, life difficulties, and quality of relationships. Three regression models were compared with and without, SES measures (occupational class, household income and parental education) and cognitive ability. On academic and cognitive attainments, cognitive ability at age 13 had substantially more explanatory power than the SES measures together. On measures of adolescent difficulties and on family relationships, cognitive ability was important, but gender and to a lesser extent, household income and parental education had some effects. Claims that class background and family income are of central importance for adolescent outcomes are not supported.

The present study examines whether breastfeeding is associated with neuro-developmental advantages at 9 months of age on a standardised measure of infant development in a large cohort study of Irish children. It is hypothesised that if breast-milk confers an independent benefit, infants who were never breastfed will have reached fewer developmental milestones than those who were partially or exclusively breastfed, after controlling for putative confounding variables. Families with infants aged 9-months were recruited as part of a nationally representative sample for the birth cohort of the Growing Up in Ireland study (n = 11,134). Information was collected from mothers on breastfeeding practices, socio-demographic characteristics and developmental progress during a household interview. Parent-report items on development covered communication, gross motor, fine motor, problem solving and personal-social skills. Analysis of pass/fail status in each developmental domain using binary logistic regression showed a positive effect of any breastfeeding on gross motor, fine motor, problem solving and personal-social skills (but not communication) and these remained after adjustment for a range of confounding variables. There was, however, little evidence of a dose–response effect or advantage of exclusive over partial breastfeeding. A clear advantage of breastfeeding on infant development was demonstrated. However, the lack of a dose–response association on pass rates suggests that the breastfeeding effect may be confounded by other unobserved factors or that there is a critical threshold during which time the effect of breast milk may be particularly salient for bolstering brain development.

The present study investigated the home learning environment of three to five-year-old children (n = 429) living in an area designated as socio-economically disadvantaged, involved in the Area Based Childhood (ABC) programme, compared to a nationally representative sample of three-year-old children (n = 9793), from the Growing Up in Ireland (GUI) Study. Statistical analysis of the frequency of engagement in home learning activities across both samples, revealed a significant difference in the environments to which children are exposed, with families from the GUI sample engaging more frequently in these activities than families from the ABC sample. Among the family demographic factors investigated, parent’s age and household type were significantly related to the frequency of engagement in home learning activities. Based on these findings, policy and practice implications are discussed.

The prevalence of low birth weight is an important aspect of public health which has been linked to increased risk of infant death, increased cost of care, and a range of later life outcomes. Using data from a new Irish cohort study, I document the relationship between birth weight and socio-economic status. The association of maternal education with birth weight does not appear to be due to the timing of birth or complications during pregnancy, even controlling for a wide range of background characteristics. However, results do suggest intergenerational persistence in the transmission of poor early life conditions. Birth weight predicts a number of outcomes at age 9, including test scores, hospital stays and health. An advantage of the data is that I am able to control for a number of typically unmeasured variables. I determine whether parental investments (as measured by the quality of interaction with the child, parenting style, or school quality) mediate the association between birth weight and later indicators. For test scores, there is evidence of non-linearity, and boys are more adversely affected than girls. I also consider whether there are heterogeneous effects by ability using quantile regression. These results are consistent with a literature which finds that there is a causal relationship between early life conditions and later outcomes.

The prevalence of obesity in children is rapidly rising, leading to many serious consequences worldwide. In 2005, the World Health Organisation (WHO) Regional Office for Europe issued recommendations and guidelines for regular collection of data on weight, height, and waist and hip circumference in children worldwide in order to monitor prevalence trends of growth, overweight and obesity. The Department of Health and the Health Service Executive commissioned the National Nutrition Surveillance Centre, based at the School of Public Health, Physiotherapy and Population Science in University College Dublin, to carry out this surveillance work in the Republic of Ireland.

This report presents the findings from three waves of the WHO Childhood Obesity Surveillance Initiative survey in the Republic of Ireland in 2008, 2010 and 2012. In 2008, 163 randomly selected primary schools participated in this project and in the first round the protocol as set out by the WHO for participating countries was followed. The target age was children aged exactly 7 years. In the subsequent two waves, the same WHO protocol was followed and the same schools were contacted again and this time, as well as 7-year-olds, 9-year-olds were also selected for participation in the second round. In the third round, 7-year, 9-year, as well as 11-year-olds were included.

This means that there are three cross-sectional surveys of 7-year-old children, two cross-sectional surveys of 9-year-olds and one cross-sectional comparison group of 7-, 9- and 11-year-old children. Using a unique identifier there are also two cohort groups of the same children followed on two separate occasions from ages 7 to 9 and ages 9 to 11, respectively. In this report, we also compare the data on 9-year-old children to the findings from the Growing Up in Ireland Cohort study.

The purpose of the study was, 1) to identify risk and protective factors that predict academic achievement in low socioeconomic status (SES) pupils in Ireland; and 2) to establish if these predicting factors are unique and applicable only in low-SES pupils. Using two waves of the Irish nationally representative longitudinal data, a multi-informant design was applied to analyse data from over 7,000 children along with their caregivers and teachers. A series of multilevel regression analyses were performed to compare data from low-SES and high-SES pupils. After controlling for prior achievement, findings suggested that academic achievement in both low and high-SES pupils are promoted by educational aspirations, attentional skills and being in the rural area. The strength of the association between protective factors and academic achievement, however, varies between the two groups. Nonetheless, close parent-child relationship in low-SES female pupils appears to be a unique factor that promotes academic resilience that does not apply to the rest of the pupils. The study contributes credible evidence and fresh insights into protective factors that exclusively promote academic resilience in low-SES pupils. From the perspective of policy and intervention, the differentiated knowledge gained is useful to inform the provision of targeted efforts aimed at closing the gap in achievement between pupils from different socioeconomic backgrounds.

The purpose of this report is to investigate the known correlation between non-traditional family structures and poor outcomes for children.

Discussions of this topic often focus on the distinction between two-parent families and one-parent families but this distinction can be misleading. In the Irish case, the crucial distinction is between children raised by parents who are married and children raised by a lone-parent who has never been married. The focal point here is non-marriage.

This is important since non-marriage appears to be highly selective because the least privileged groups in Irish society are more likely to have children outside of marriage and at a relatively early age.

This argument suggests that selection bias accounts for much of the association between family structure and child outcome i.e. growing up in a non-traditional family has little ‘direct’ or ‘causal’ effect on a child’s outcome. A large body of literature exists which documents a correlation between non-traditional family structure and poorer child development but researchers disagree as to whether this association represents a true causal effect.

The primary objective of the current study, therefore, is to test this selection argument and to examine the extent to which selection effects can account for differences in child wellbeing in various family types.

The purpose of this study is to investigate the influence of background and school factors on second-level students’ attitudes toward Irish as a school subject drawing on the Growing Up in Ireland study. The study focuses on the perceptions of the core subjects, English, Mathematics and Irish, and presents a profile of students who find the Irish language interesting or difficult. The study enables us to investigate the attitudes of teenagers towards the language in a systematic way, including personal, school and other characteristics that may have an impact on attitudes towards the Irish language.

The quality of the interparental relationship bears important implications for children’s socioemotional development. Given evidence that relationship satisfaction among parents tends to decline over time this study examined how change in parents’ relationship satisfaction from nine-months-old until nine-years-old related to children’s socioemotional difficulties at nine-years-old. Participants were 2074 mothers, fathers, and their child (55.1% male) recruited through random sampling of the Child Benefit Registrar by Growing Up in Ireland cohort study. Mothers ranged in age from 18 to 40 years (M = 31.06, SD = 4.70) and fathers ranged in age from 18 to 60 years (M = 33.50, SD = 5.54). Mothers and fathers completed the Dyadic Adjustment Scale at nine-months-old and at nine-years-old whereas child socioemotional development was assessed via teacher report on the Strengths and Difficulties Questionnaire at nine-years-old. Residualised change analysis indicated that both parents experienced declines in relationship satisfaction from nine-months-old until nine- years-old. However, in families where initial levels of relationship satisfaction were high, there was no significant association between decline in satisfaction and child socioemotional difficulties. Conversely, in couples where initial levels of satisfaction were low, mothers, but not fathers, who experienced further declines had female, but not male, children with more socioemotional difficulties at nine years (β = −0.22, p = 0.01; R2 = 0.15, F = 2.31, p = 0.02). These findings highlight the need for carefully tailored interventions aimed at promoting couple relationship satisfaction during transition to parenthood such that the negative impact on children of any decline experienced over time can be mitigated.

The relationship between parental background and children’s educational outcomes has been a dominant theme within the sociology of education. There has been an on-going debate as to the relative merits of explanations which focus on the role of socio-cultural reproduction and those which focus on rational choice. However, many empirical studies within the social stratification tradition fail to allow for children’s own agency in shaping the relationship between social background and schooling outcomes. This paper draws on the first wave of a large-scale longitudinal study of over 8,000 nine-year-old children in Ireland, which combines information from parents, school principals, teachers and children themselves. Both social class and parental education are found to have significant effects on reading and mathematics test scores among nine year olds. These effects are partly mediated by home-based educational resources and activities, parents’ educational expectations for their child, and parents’ formal involvement in the school. More importantly, children’s own engagement with, and attitudes to, school significantly influence their academic performance. The influence of children’s own attitudes and actions can thus reinforce or mitigate the effect of social background factors. The analysis therefore provides a bridge between the large body of research on the intergenerational transmission of inequality and the emerging research and policy literature on children’s rights.
