International research has pointed to the social and academic adjustment required of young people moving to secondary education and the importance of social support in easing this transition. However, studies have rarely looked at the simultaneous impact of different social networks on this process and how these networks may mediate the influence of social background. This paper draws on Growing Up in Ireland data to look at the influence of parents, peers and teachers on two dimensions of the transition process, which capture social, socio-emotional and academic aspects of the adjustment: the ease of settling into secondary education, as measured by parents’ reports of transition difficulties among their children, and academic adjustment to secondary education, as reflected in changes in young people’s academic self-image. Parental support is found to play a crucial role in helping young people adjust to the new school setting but, contrary to much previous research, formal involvement in their children’s schooling, especially in helping with homework, plays a much less important role. Over and above supportive relations, parental cultural, economic and social resources are found to play a direct role in improving young people’s confidence as learners and in enhancing transition experiences. Peer networks typically grow larger over the transition to secondary education but those young people who were more socially isolated at primary level experience greater difficulties. In keeping with previous research, the quality of relations with teachers emerges as a key driver of academic and social adjustment to secondary education.

This study draws on data on Growing Up in Ireland (GUI) Cohorts ’98 and ’08 to document changes in the lives of adolescents over the period 2011/12 to 2021/22, building on an earlier study (Smyth, 2022) which compared their experiences at nine years of age. This decade was a period of considerable social and policy change, including reform of the junior cycle, growing digitalisation and the disruption of the pandemic to all aspects of young people’s lives. Changes were also evident in the profile of young people and their families, with increasing cultural diversity, higher education levels among parents, lower levels of financial strain and increasing numbers with a disability among members of Cohort ’08 than among their older cohort counterparts. The study looks at changes in 13-year-olds’ relationships with their parents and peers, in their day-to-day activities and in their experiences of school. The main research questions addressed by the study are: How have the quality of relationships, experience of learning and activities engaged in by adolescents changed over the course of a decade? To what extent do any such changes reflect differences in the family characteristics of the young people? Are any such changes more evident for boys or girls or for young people from different social backgrounds? Is differentiation by gender and social background in adolescents’ social worlds less evident for the younger cohort than previously?

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?

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 world-wide COVID-19 pandemic significantly disrupted education, with school closures leading to a shift to remote learning. Existing and emerging research has shown that even a relatively short period of missed school has negative consequences for academic and social outcomes among children and young people, especially for those from more vulnerable families. While emerging research drawing on cross-sectional data has focussed on how the pandemic has affected immigrant youth, there is a paucity of longitudinal studies in this field. In this paper, we used the longitudinal Growing Up in Ireland study to investigate and analyse the wellbeing of migrant-origin 12-year-olds in Ireland during the COVID-19 pandemic. Our research shows that compared to their Irish peers, immigrant adolescents had poorer wellbeing, partly related to differences in family support for remote learning, in experiences of poor-quality interaction with peers and in levels of family strain.

This article draws on the Growing Up in Ireland study and the Scottish sample of the Millennium Cohort Study to explore the factors influencing inequalities in children’s cognitive skills on entry to primary education. It adopts a multidimensional comparative approach, which directly compares the effects of parental education and household income on several cognitive outcomes (vocabulary, language, reading and numbers) among five-year-old children and examines the extent to which inequalities in these outcomes are mediated by the home learning environment (HLE) and early childhood education (ECE). Home learning environment plays a stronger role in explaining actual vocabulary differences in Ireland while it plays a stronger role in school readiness (teacher-assessed skills) in Scotland. In both countries, use of centre-based care at 9 months and 3 years was markedly higher among the top income quintile. Centre-based care is found to play a mediating role in school readiness in Scotland. Nonetheless, the findings point to important direct effects of family background even when HLE and childcare are taken into account. The analyses point to differences in the trajectory of early skill development in the two countries, with the impact of early skill development being more marked in Scotland than Ireland. Comparative analyses of this kind thus yield important insights for policy development by highlighting potential domains (such as childcare) or timing (preschool or within-school) for intervention.

The sudden health and economic crisis brought about by the COVID-19 pandemic affords an opportunity to examine the impact of economic disruption to children and families. Any negative effects on the well-being of children are important to consider in relation to both short- and long-term outcomes. Using pre-pandemic and mid-pandemic waves of the longitudinal Growing Up in Ireland study, we examined whether the impact of economic disruption was equivalent for families who were (or were not) financially vulnerable pre-pandemic. We then investigated whether economic disruption was associated with a negative effect on the emotional well-being of 12-year-olds, and if there was evidence for such a negative effect being mediated through a lack of material resources or strain on family dynamics. Our results indicated that middle-income rather than lowest-income families experienced the most economic disruption, likely reflecting the sector-specific nature of business closures in the pandemic. Families who were financially vulnerable pre-pandemic were less likely to have had suitable resources for homeschooling. Both falls in income and strain in family relationships, such as arguing more with their parents, were associated with poorer scores on a measure of the child’s emotional well-being. The emergency income support payment introduced at the start of the pandemic appeared to have a protective effect on the association between family income loss and child well-being, which has wider implications for policy on child poverty.

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.

Worldwide, children do not meet the recommended guidelines for physical activity (PA) and a unified approach is required to increase children’s engagement in PA. Parents, are increasingly regarded as playing a key role in children’s PA behaviours. Physical activity parenting (PAP) is growing as a research field and refers to parental behaviours intended to influence children’s investment in PA. Using the perspectives of both parent and child, this research aims to identify PAP practices (positive and negative) engaged by Irish parents and to examine how PAP is embedded within a socioecological context. A purposive sample of 116 families in Ireland were included in the study. Families were stratified by social class, location, and family structure. Parents and children were interviewed and a secondary analysis of the interview data was completed. A theoretical model and conceptual framework relating to PAP guided data analysis to identify and understand parenting practices that influence children’s PA behaviour. Data was deductively analysed and key findings indicated that PAP practices of encouragement, involvement, and facilitation were positively associated with children’s engagement in structured sport activities. Co-participation was positively associated with children’s participation in unstructured PA. Mothers and fathers differed in their PA roles, with fathers engaged to a greater extent in involvement parental practices. Children from middle and higher socio-economic class families participated in a greater repertoire of structured PA and benefited from a greater diversity of PAP practices. Family context (social class, structure, size), community resources and organisational factors mediated the presence of PAP practices. Parents’ PA attributes and parents perceptions of PA attributes were less important influencers. Successful and effective engagement of parents in PA interventions is dependent on consideration of the various social contexts that are embedded in families.

While research has investigated the effects of the Great Recession on the Irish economy using economic indicators or cross-sectional household-level data, this research note applies group-based multitrajectory modelling to provide a more nuanced approach. Using nationally representative, longitudinal data from the Growing Up in Ireland study, we analyse patterns in three common measures of economic well-being (financial strain; disposable income; material deprivation) across Irish households in the period leading up to, during and after the Great Recession, and subsequently, break down the characteristics for each group of trajectories. We identify six distinct trajectory clusters, which all indicate declining income and increasing financial strain from the start to the height of the economic depression. However, trajectory groupings show that experiences were far from uniform, with previous economic well-being and demographic characteristics shaping the household experience. Implications for future research are discussed.

In today’s increasingly diverse societies, a key question is how to foster the structural integration of immigrants and their descendants. While research indicates that migrant educational underachievement is a serious issue, relatively little is known about achievement gaps at younger ages and in relatively new immigration countries. The current study sets out to estimate the size of disparities by migration background at age five (i.e. when they start school) and explores the causes of these gaps. It does so in a context that offers a compelling but under-researched case: the Republic of Ireland. It draws on the Growing Up in Ireland (GUI) data, a national longitudinal study of children in Ireland. The results suggest that some disparities by migration background already existed at the start of primary school, but also that gaps were limited to verbal skills and differed widely across groups. Moreover, social background only played a relatively minor role in explaining the differences, whereas the child’s first language was a powerful predictor of disadvantages by migration background in verbal skills.

Background
There are few prospective studies of factors that mediate the association between exposure to adverse childhood experiences (ACEs) and obesity in adolescence. Our aim was to address this limitation.

Methods
We used prospective data from the Growing up in Ireland cohort study, with measurements at 9, 13, and 18 years old. The exposures were 14 adverse experiences before age 9. The main outcome was body mass index (BMI) at 18 years. Mediators were daily activity, diet quality, self-image and behavioural difficulties at 13 years.

Results
Among the 4561 adolescents in the final cohort, 77.2% experienced any adversity, 50.5% were female and 26.7% were overweight/obese at 18 years. BMI Z was higher at ages 9 (0.54 vs 0.43, p < 0.05, 95% CI of difference: −0.22, −0.01) and 13 years (0.50 vs 0.35, p < 0.05, 95% CI of difference: −0.25, −0.06), in those exposed to an ACE, compared to those unexposed. Structural equation models revealed that behavioural difficulties (β = 0.01; 95% CI: 0.007–0.018, p < 0.001) and self-concept (β = 0.0027; 95% CI: 0.0004–0.0050, p = 0.026) indirectly mediate the association between exposure to ACEs and BMI at 18 years.

Conclusions
The association between ACEs and BMI in adolescence is mediated by behavioural difficulties and self-concept.

Impact

• In a previous study, we found modest associations between exposure to a range of adverse childhood experiences and weight gain at 13 years of age.
• The strength of the association between adverse childhood experiences and weight gain was lower at 18 years of age compared to the association observed at 13 years and was no longer significant after controlling for confounding and including possible mediators.
• The association between adverse childhood experiences and BMI in adolescence is indirectly mediated by behavioural difficulties and self-concept.

Background
Children with a parent who smokes are more likely to become substance users than those who do not have a parent who smokes. In this study, we examined whether childhood or early adolescent exposure to primary parent smoking increased the risk of subsequent teenage alcohol and drug use at ages 17–18 years.

Methods
For this longitudinal observational study, we analysed data from 6039 teenagers and their parents from the waves 1–3 of the Growing up in Ireland Cohort 98’ Study. Parental smoking was assessed at baseline (9 years) and wave 2 (13 years) with responses coded as yes or no. The primary parent was defined as the person who provided most care and who knew most about the Study Child, usually the mother or mother figure for 98% of study participants. Teenage alcohol and drug use assessed at ages 17–18 years (wave 3) was determined by responses to the question “Have you ever consumed alcohol?” (answers yes or no), drug use was assessed by questions on ever trying aerosols/gas, cannabis, and non-prescribed drugs, with those answering yes being classified as other-drug ever users. We did a logistic regression analysis to examine the associations between parents’ smoking on teenage alcohol and drug use, controlling for covariates: gender, education, income, education, region, and household type. Ethics approval for the GUI project was obtained from the Health Research Board.

Findings
Of the 6039 teenagers included in our study, 2968 (49%) were female, 3070 (51%) were male, 5351 (89%) ever used alcohol, 5065 (85%) were current users, and 2098 (35%) used other drugs. Rates of primary parent smoking were 31% (n=1883) in wave 1 and 30% (n=1829) in wave 2. After adjusting for other exposures known to be associated with teenage substance use, primary parent smoking at waves 1 and 2 was associated with higher odds of teenage alcohol ever use (adjusted odds ratios [aORs] 1·89 [95% CI 1·44–-2·46] at wave 1 and 1·53 [1·20–1·98] at wave 2), current alcohol use (1·88 [1·50–2·36] and 1·59 [1·28–1·97]) and other-drug ever use (1·699 [1·45–1·95] and 1·71 [1·47–1·98]).

Interpretation
Teenagers aged 17–18 years exposed at ages 9 and 13 years to parental smoking were more likely to report significantly higher odds of alcohol and drug use at age 17–18 years. The finding that exposure to parent smoking in childhood increases the risk of teenage alcohol and other drug use suggests a need for interventions aimed at parents who smoke Limitations include potential unmeasured or residual confounders and reliance on self-reported teenage substance use behaviours.

We analyse parental smoking and cessation (quitting) associations with teenager e-cigarette, alcohol, tobacco smoking and other drug use, and explore parental smoking as a mechanism for social reproduction. We use data from Waves 1–3 of Growing Up in Ireland (Cohort ’98). Our analytic sample consisted of n = 6,039 participants reporting in all 3 Waves. Data were collected in Waves 1 and 2 when the children were 9 and 13 years old and in Wave 3 at age 17/18 years. Generalized Estimating Equations (GEE) models were used to analyse teenage substance use at Wave 3. Parental smoking was associated with significantly increased risk of all teenage substance use, adjusted odds ratios were aOR2.13 (ever e-cigarette use); aOR1.92 (ever alcohol use); aOR1.88 (current alcohol use); aOR1.90 (ever use of other drugs); aOR2.10 (ever-smoking); and aOR1.91 (current smoking). Primary caregiver smoking cessation (quitting) was associated with a lower risk for teenager current smoking aOR0.62, ever e-cigarette use aOR 0.65 and other drug use aOR 0.57. Primary caregiver smoking behaviour had greater associations than secondary, and age13 exposure more than age 9. Habitus seems to play a role and wealth was protective for teenage smoking. The findings suggest that prevention interventions should target both caregivers and their children.

Childhood obesity is a growing concern worldwide. The association between childhood obesity and maternal smoking and/or paternal smoking has been reported. However, few studies have explored the association between childhood obesity and exposure to carers’ smoking status. This study aimed to assess the impact of carers’ smoking status on childhood obesity in a cohort of children enrolled in the Growing up in Ireland (GUI) study. Participants from the GUI infant cohort were categorized into four groups based on their exposure status: Neither caregiver smoked (60.4%), only primary caregiver smoked (13.4%), both caregivers smoked (10.9%). Exposure to primary carers’ smoking (98% are biological mothers) was found to be significantly associated with childhood overweight/obesity at age three (Odds Ratio: 1.30, 95% CI: 1.17–1.46) and at age five (OR: 1.31, 95% CI: 1.16–1.49). Exposure to both carers’ smoking status was significantly associated with increased odds of childhood overweight/obesity across both waves. These findings emphasize the health burden of childhood obesity that may be attributable to maternal smoking postnatally and through early childhood in Ireland.

Background
Adolescence is a critical transition point for body weight. Personality traits are associated consistently with weight and obesity risk in adulthood. We examined whether personality, particularly Conscientiousness (the tendency to be organized, disciplined, and responsible), is associated with weight outcomes between ages 13 and 17.

Methods
Data are drawn from the Growing Up in Ireland suites of studies. Parents rated their child’s personality at age 13, and trained staff measured weight and height at ages 13 and 17 (N = 4962). Logistic regression was used to predict risk of incident obesity and obesity remission between ages 13 and 17.

Results
Among children who were not in the obesity category at age 13, higher Conscientiousness was associated with lower risk of moving into the obesity category by age 17, and, among children with obesity at age 13, Conscientiousness was associated with greater likelihood of moving to the nonobesity category by age 17. These associations were independent of sociodemographic characteristics, parent body mass index, and were similar across gender. The other five-factor model personality traits were unrelated to weight outcomes.

Conclusions
Conscientiousness is one trait psychological factor implicated in weight transitions across a critical period during adolescence.

Children with disabilities experience significantly poorer socio-emotional outcomes than their peers without disabilities. However, research evidence is scarce about children with both disability and migration background, the group which this study aimed to investigate using data from a national longitudinal study. Secondary data analyses were conducted on a sample of 7290 children (weighted with missing values imputed). Significant differences in socio-emotional outcomes were found in relation to impairment status but not in relation to migration. Having an impairment and activity limitation significantly increased the likelihood of experiencing poorer socio-emotional outcomes over time. Our findings highlight a higher risk of socio-emotional problems among children with disabilities, especially among children from lower income backgrounds and with parents with lower educational attainment. These findings clearly require policy development on two fronts: to raise professional and community awareness on these issues and to strengthen the capacity of health, education and social care systems to support schools, families, and communities.

A small proportion of children experience social-emotional difficulties from early childhood onwards. Longitudinal studies with nationally representative samples are needed to identify the prevalence and the characteristics of children and families persistently experiencing these difficulties. Secondary analysis of data collected on over 7500 Irish children and with the Strengths and Difficulties Questionnaire as the primary indicator, found that 6% of children when they were five year olds and 8% when they were nine-years, had above threshold scores that warranted further investigation. A smaller proportion—2.9% had elevated scores at both ages. Logistic regression analyses found that children with one or more developmental disabilities were up to six times more likely to have sustained difficulties. There were also significant associations with the lower education attainment of primary caregivers and the socio-economic deprivation of families. Primary caregivers and teachers reported higher conflict in their relationships with these children. Although the number of Irish children presenting with continuing social-emotional difficulties is small, they can present an ongoing and future societal cost in terms of the impact on family relations and demands placed on educational, health and social services. This study identified the children and families who are at greatest risk and for whom targeted early intervention services could be provided.

Identifying the clustering and correlates of physical activity (PA) and sedentary behavior (SB) is very important for developing appropriate lifestyle interventions for children and adolescents. This systematic review (Prospero CRD42018094826) aimed to identify PA and SB cluster patterns and their correlates among boys and girls (0-19 years). The search was carried out in five electronic databases. Cluster characteristics were extracted in accordance with authors’ descriptions by two independent reviewers and a third resolved any disagreements. Seventeen studies met the inclusion criteria and the population age ranged from six to 18 years old. Nine, twelve, and ten cluster types were identified for mixed-sex samples, boys, and girls, respectively. While girls were in clusters characterized by “Low PA Low SB” and “Low PA High SB”, the majority of boys were in clusters defined by “High PA High SB” and “High PA Low SB”. Few associations were found between sociodemographic variables and all cluster types. Boys and girls in “High PA High SB” clusters had higher BMI and obesity in most of the tested associations. In contrast, those in the “High PA Low SB” clusters presented lower BMI, waist circumference, and overweight and obesity. Different cluster patterns of PA and SB were observed in boys and girls. However, in both sexes, a better adiposity profile was found among children and adolescents in “High PA Low SB” clusters. Our results suggest that it is not enough to increase PA to manage the adiposity correlates, it is also necessary to reduce SB in this population.
