Differentials in physical activity (PA) between social and economic groups has been shown to contribute significantly to social gradients in health and life expectancy, yet relatively little is known about why differentials in PA emerge. This paper uses longitudinal data on a nationally representative sample of 6,216 young people aged between 9 and 18, from Ireland, to measure the role of family, school and neighbourhood level factors in accounting for differentials in PA trajectories between groups of young people, defined by level of maternal education, whilst adjusting for the individual characteristics of the young person (sex, age, personality, body mass index and health-status). Levels of PA fall significantly across the sample between 9 and 18, and the decline in PA is larger for the children of lower educated mothers. We find a clear gradient in PA at each age by maternal education for both males and females. Descriptive analyses found social gradients in the majority of our risk factors. Using multi-level, linear spline regression models to decompose differentials between groups, we find that family-level mechanisms account for the biggest proportion of the differential in PA for both males (50.8%) and females (35.1%). Differences in income across maternal education categories accounted for 24.1% of the differential for males and 14.7% among females, making it the second most effective mechanism in explaining the social patterning of PA. Neighbourhood-level processes resulted in a modest reduction in the same differential, while school level processes had the effect of equalising differences in PA across maternal education groups.

Objective
Early complementary feeding has been shown to increase the risk of overweight, obesity and chronic diseases later in life. Poor compliance with current guidelines on complementary feeding has been reported by Irish studies. The aim of the present paper is to identify predictors of early complementary feeding in order to help health professionals target population groups in greater need of dietary intervention as well as to provide effective advice.

Design
Cross-sectional analysis of the national, longitudinal Growing Up in Ireland study.

Setting
Data were derived from the first wave (2007–2008) of the Growing Up in Ireland infant cohort.

Subjects
A cohort of mothers (n 11 134) from the Republic of Ireland, interviewed when their infants were 9 months of age.

Results
Of the infants, 1469 (13·5 %) had been regularly taking solids in the period between 12 and 16 weeks; this percentage increased to 47·0 % of the sample in the period between 16 and 20 weeks. Timing of formula feeding commencement, high maternal BMI and choosing a relative as the infant’s minder were strongly associated with early introduction of solids both in bivariate and multivariate analysis. Those infants who started formula feeding at >4 months were 88·4% less likely to be introduced to solids early compared with those who started at <2 months (OR = 0·116; 95% CI 0·072, 0·186; P < 0·001).

Conclusions
The results demonstrate that biological, social and behavioural aspects exert an important role in infant feeding practices. These findings are relevant to the design of policies and intervention programmes aimed at educating parents.

Technological advancement has seen a rise in computer-based and online gaming, and the online space has facilitated a proliferation in gambling options that increasingly adopt game-like features. There is a concern that gaming in childhood could predispose subsequent engagement with gambling behaviors, which has drawn the attention of parents, researchers, governments, and the European Union. To inform policy and legislation aimed at mitigating gambling-related harms, this research uses three waves of longitudinal data from Ireland to examine whether computer game engagement at 9-years-old (collected in 2007/8), and online gaming at 17 and 20, is associated with gambling participation in young adulthood. Multiple regression models, adjusting for a range of socio-economic and health characteristics, revealed that online gaming at 17 was associated with 1.4 higher odds of more frequent online gambling at 20 years (p = 0.011), while online gaming at 20 was associated with a 1.7 higher odds (p < 0.001). However, no association between early computer-based gaming at 9 years and subsequent gambling behaviors at 20 was uncovered for this cohort (born in 1998). Given more recent introductions of loot boxes and social casino games, continuous research is needed for future cohorts which may be greater affected by such developments.

Economic recessions have been linked to adult health, but few studies have examined how recessions influence the health of young children. This study examined the impact of life transitions linked to the recent financial crisis on the health of young children in Ireland. Data came from the Growing Up in Ireland Infant Cohort Study (n = 11,134), which assessed children before (2008), during (2011), and after (2013) the Great Recession that followed the financial crisis of 2008 and incorporated questions on the impacts of the financial crisis on families. Using fixed-effects models to control for confounding, we found that a reduction in welfare benefits during the recession was associated with a significant increase in the risks of asthma (β = 0.014, 95% confidence interval (95% CI): 0.004, 0.023) and atopy (β = 0.014, 95% CI: 0.001, 0.027). While parental job loss was not associated with child health, a reduction in working hours was associated with increased reports of child health problems (β = 0.024, 95% CI: 0.004, 0.043), as were difficulties affording basic necessities (β = 0.019, 95% CI: 0.001, 0.038). Results suggest that failing to protect vulnerable families and children during economic recessions may have long-lasting implications for child health.

This article investigates the dynamics of the gender pay gap using an administrative dataset of Irish graduate earnings. Although male and female graduates have similar earnings initially, a substantial gap emerges in the 10 years after graduation. We focus on three possible sources: childbirth, field of study, and job mobility. We find that the gap is driven by the earnings of mothers, which fall by 24 per cent relative to trend immediately after childbirth and this effect is evident for all field groupings. We examine and dismiss the possibility that the gender difference is driven by job mobility; in fact, almost all the difference arises for job stayers. Although there is a large and persistent reduction in average hours of work after childbirth, this does not seem to explain all of the emerging gap. Our results suggest that policy measures should focus on earnings dynamics within firms.

Background
Exposure to adverse childhood experiences (ACEs) is associated with a 30 to 50% increased risk of obesity in adolescence. The role of ACEs as a determinant of weight loss among overweight and obese children remains unclear.

Methods
Among 8568 nine-year-old children randomly sampled in 2007/2008 for the Growing up in Ireland cohort, 2210 were overweight or obese at 9 years and provided complete follow-up data at age 13 and 18 years. Structural equation and natural effects mediation models tested for a direct causal relationship between ACEs before 9 years and remission risk at 18 years, and indirect effects mediated via daily activity, diet quality, self-image and behavioural difficulties and BMI at 9 years.

Results
Among the 1676 adolescents that were overweight or obese at age 9, 46% achieved healthy weight status by age 18; 56% (n=618) of overweight children and 27% (n=153) of obese children), 13% experienced an ACE, and 41% were female. Exposure to an ACE was associated with a higher BMI Z at ages 9 (0.47 vs 0.36, p < 0.05) and 13 years (0.39 vs 0.29, p < 0.05) and reduced the odds of achieving healthy weight status at age 18 by 27% (OR: 0.73, 95% CI:0.54- 0.99). Overweight and obese children exposed to an ACE had lower household income, higher behavioural difficulties, and lower self-concept at ages 9, 13 and 18. Children exposed to an ACE were also 2 to 3-fold more likely to have started smoking before 12 years old and 50% more likely to smoke more than 10 cigarettes a week regularly vape. Behavioural difficulties, self-concept and baseline weight status, but not smoking or dietary habits, mediated the association between ACE exposure and achieving healthy weight at age 18.

Conclusion
Among overweight and obese children, exposure to ACEs indirectly reduces the likelihood of achieving healthy weight status at age 18, mediated by its effects on weight in childhood, and behavioural difficulties and self-concept in mid-adolescence. These findings highlight the complex factors that influence weight loss among overweight and obese children exposed to adverse experiences early in life.

Background
Low socio-economic status (SES) is a persistent risk factor for educational attainment. Parent expectations and student’s academic self-concepts contribute to this link; however, few studies have examined how changes in these constructs over time contribute to SES gaps in attainment and how teachers may buffer against the consequences of these changes.

Aims
We examine SES differences in (a) changes in parent expectations and academic self-concepts from primary to secondary school and (b) interactions between teacher–student interaction quality and parent expectations to uncover the role these processes play in SES differences in attainment.

Sample and Methods
Using the Growing Up in Ireland cohort (N = 5190), children reported on their academic self-concepts (9 and 13 years); quality of teacher interactions (13 years); and third-level attainment (20 years). Primary caregivers reported on their educational expectations and SES (9 and 13 years).

Results
From 9 to 13 years, children from low SES families experience a steeper drop in academic self-concept and no rise in their parents’ expectations compared with their high SES peers. Both initial levels and changes in children’s self-concepts and parents’ expectations predicted attainment, with parents’ expectations a stronger influence in low SES families. Teacher–child interactions at age 13 moderated the effect of parents’ expectations on attainment; however, this was cumulative for low SES children and compensatory for high SES children.

Conclusions
We discuss how findings regarding these developmental processes can be used in school policy and practices aimed at addressing SES differences in educational attainment.

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, which follows 8568 children from 9 to 20 years, we examine how different MH difficulties, and their 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, but if voting, are more likely to vote for an antiestablishment party. Adolescents with chronic emotional MH difficulties starting in childhood also report lower trust in politicians, are less likely to register to vote, and report a higher likelihood of voting for an antiestablishment party when voting. Additionally, they evidence lower levels of external political efficacy.

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.

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.

Background
Tobacco use is closely linked to social and health inequalities, including economic vulnerability, morbidity, and premature death. Young adults with disabilities experience significant social and material hardships, which may be exacerbated by tobacco use. Limited research exists on smoking and e-cigarette use in this population. This study examines the prevalence of disability among young adults in Ireland, compares smoking and e-cigarette use between those with and without disabilities, identifies protective and risk factors, explores shared risk factors, and evaluates disability as an independent risk factor for smoking and e-cigarette use.

Methods
We analysed weighted data from 4,729 20-year-olds in the Growing Up in Ireland Cohort ’98 study who were present in Waves 1 (2008), 3 (2016), and 4 (2019). Current smoking, e-cigarette use, disability (excluding mental ill-health) and all other variables were assessed at Wave 4, while peer smoking data were drawn from Wave 3. Analyses were conducted using SPSS version 27.

Results
18.1% of participants reported a disability, which was associated with significantly higher smoking (41.8% vs. 36.7%) and e-cigarette use (16.1% vs. 12.9%). Protective factors against both behaviours included being female (OR 0.87 for smoking, OR 0.57 for e-cigarettes), later smoking initiation (OR 0.35, OR 0.62), living in two-parent families (OR 0.83, OR 0.70), and physical activity (smoking only). Risk factors included having peers who smoked (OR 3.67 for smoking; OR 2.36 for e-cigarette use) and caregivers who smoked (OR 1.48, OR 1.48), being employed at age 20 (OR 1.58, OR 1.48), and social media engagement (smoking only). Young adults with disabilities were significantly more likely to experience risk factors (e.g., earlier smoking initiation, caregivers who smoked, one-parent families, employment) but were less likely to have peers who smoked or engage with social media. Disability was independently associated with a higher likelihood of smoking (by 54%) and e-cigarette use (by 36%) after adjusting for protective and risk factors.

Conclusion
Higher smoking and e-cigarette use in 20-year-olds with disabilities adds further inequality to their lives. Increased awareness, targeted surveys and focused prevention and therapeutic interventions are required to reduce inequalities in this population and hasten the tobacco endgame.

Background
Childhood adversity is a well-established risk factor for psychopathology; however, many who experience adversity do not go on to develop psychopathology. Poor self-concept and poor parental support are known risk factors for adolescent psychopathology, which may account for some of this mechanism.

Aims
To investigate candidate mediators in the relationship between childhood adversity and psychopathology.

Method
We used data from the age 9 and 13 waves of the child-cohort of the Growing Up in Ireland study. We undertook mediation analysis by path decomposition of the relationship between childhood adversity and psychopathology (internalising and externalising problems) at age 13 and persistent psychopathology. Candidate mediators were self-concept, parent–child relationship and hobby participation at age 9.

Results
Childhood adversity was reported by 28.2% of participants, and was significantly associated with internalising and externalising problems. Parent–child conflict mediated the relationship between childhood adversity and both age 13 and persistent psychopathology, accounting for 52.4% of the relationship between childhood adversity and persistent externalising problems (indirect odds ratio, 1.30; 95% CI 1.19–1.43) and 19.2% for persistent internalising problems (indirect odds ratio, 1.24; 95% CI 1.15–1.34). There was a small mediating effect of self-concept. Hobby participation and positive parent–child relationship did not mediate these relationships.

Conclusions
Parent–child conflict explains almost half the relationship between childhood adversity and persisting externalising problems in adolescence, and a fifth of the relationship with persisting internalising problems. This suggests parent–child conflict is a good target for interventions in childhood to prevent adolescent psychopathology.

Growing Up in Ireland (GUI) is the national longitudinal study of children and young people in the Republic of Ireland and has followed two cohorts for over ten years to date: Cohort ’98 who were recruited into the study at age nine years and Cohort ’08, recruited at age nine months. The study aims to describe the lives of Irish children and young people in terms of their development, with a view to positively affecting policies and services available for them. Traditionally, data collection involved in-home visits from an interviewer who conducted face-to-face interviews, recorded physical measurements of study participants and administered cognitive assessments. However, with the onset of the COVID-19 pandemic and the associated restrictions, significant adaptations were required to these methods to ensure data collection for the pilot and main fieldwork for Cohort ’08 at age 13 could continue to the expected timeline. Face-to-face interviews with participants were replaced with telephone and web-based modes, interviewer training was conducted online, online resources were made available for interviewers and participants and COVID-19 related items were added to questionnaires. In addition to the scheduled data collection, a special COVID-19 survey was also conducted on both GUI cohorts in December 2020 to explore the impact of the pandemic on participants’ lives. This paper outlines the adaptations made to traditional data collection methods in GUI, highlighting the challenges that were met, but also the benefits of some changes that may be worth incorporating into future waves of GUI.

There has been a good deal of attention in Irish policy discourse to housing supply and affordability. However, there has been less focus on the extent to which the quality of housing impacts the wellbeing of children and their parents. This study addresses this gap in knowledge by using data from Growing Up in Ireland (GUI) Cohort ’08 to explore the influence of housing and neighbourhood quality on parental and child wellbeing. In particular, it looks at how the length of time households have spent experiencing inadequate housing can shape families’ wellbeing. The study adopts a multidimensional approach to measuring inadequate housing, capturing whether the home is unsuitable (in terms of size or problems like damp), whether the household struggles to adequately heat the home, lack of access to a garden or play space, the number of residential moves and the type of tenure. In addition, neighbourhood quality is assessed in terms of local disorder, having low social capital (with few family and friends in the area) and having access to fewer local services. Child wellbeing is measured using the Strengths and Difficulties Questionnaire (SDQ), which captures the extent of children’s socio-emotional difficulties.

The experience of sexual intercourse for the first time is a significant life event, and influenced by a range of individual, cultural and societal factors. Age of first sexual initiation is a major area of policy and research focus, as the circumstances of first sex (e.g. whether contraception was used, whether it was perceived to have occurred ‘at the right time’), and the consequences of first sex for later outcomes (e.g. diagnoses of sexually transmitted infections (STIs), early parenthood), have important implications for health and wellbeing. In this report, we use data from the ’98 Cohort of Growing Up in Ireland (GUI), the national longitudinal study of children and young people in Ireland, to examine the factors associated with age of sexual initiation among young adults, and the way in which age of first sex influences the circumstances of first sex and selected outcomes. Age and circumstances of first sex, and selected outcomes, are all based on data collected during the fourth wave of data collection for the ’98 Cohort of GUI, when the young people were 20 years of age.

New research, published by the ESRI and produced in partnership with the Department of Children, Disability and Equality (DCDE), uses Growing Up in Ireland (GUI) data to look at the profile of fathers not living full-time with their children (termed non-resident fathers in the report). The GUI study has included both resident and non-resident fathers in almost all waves of the study. While the primary focus of this report is on how best to involve non-resident fathers in future waves of the new GUI birth cohort, the report provides interesting insights on non-resident fathers and their relationships with their children. It also draws on interviews with researchers from international child cohort studies and with separated parents and NGOs working with parents in Ireland.

BACKGROUND
Early studies show that children might be ‘resilient’ when families navigate economic crises and related job loss. What resilience means is unclear, though, and why and from whom resilience is required has seldom been examined.

OBJECTIVE
I theorise children’s prosociality – helping, supporting and comforting others – as a form of transformative resilience. From a social reproduction perspective, I also consider how prosociality imbues and is influenced by caregiving relationships within families. I examine how children’s prosociality/caregiving (unpaid labour) developed in response to parents losing and regaining employment (paid labour) amid the Great Recession in Ireland.

METHOD
I rely on cohort data from children’s early years to adolescence (Growing Up in Ireland, 2008-2022). I estimate growth-curve and OLS models for prosocial development and outcomes tapping into paid and unpaid labour. Associations with parental job loss are identified net of observables while outlining conditions for causal claims. FINDINGS Children whose mothers experienced job loss are rated more prosocial than their peers from middle childhood onwards. Girls with younger siblings drive this finding. At age 13, the same group is more likely to provide regular care within the household, while their mothers scale back caregiving and reprise paid work after heightened childcare responsibilities during the crisis.

CONTRIBUTION
The study contributes to debates on the formation of prosociality, the intergenerational consequences of job loss, and the household division of labour among adults and children. Findings suggest focusing on if and how families cope with a context unequally structured by (labour) markets and gender norms.

This study examines how the presence of outdoor areas such as parks and playgrounds affects children’s well-being and how this effect is moderated by families’ socioeconomic status. Specifically, I aim to answer two research questions. First, does the presence of outdoor areas in children’s neighborhoods affect their well-being? Second, is there a differential effect depending on children’s socioeconomic status? The main part of the study uses data from the International Survey of Children’s Well-Being. The results suggest that the presence of outdoor areas in children’s neighborhoods has a positive effect on their well-being. In addition, the estimated effect of outdoor areas is larger for children from families with low socioeconomic status. Finally, findings from the Growing Up in Ireland data set suggest that children’s mental problems are a plausible mechanism through which outdoor areas affect children’s well-being. These findings have meaningful policy implications. Efforts to provide access to appropriate outdoor areas may be more likely to benefit disadvantaged children and thus reduce inequality in children’s well-being.
