Previous research has suggested that the children of teenage parents are at a high risk of developing both internalising and externalising behaviour disorders. The current study aimed to explore pathways through which children of teenage mothers show more externalising and internalising psychopathology than their peers whose parents were older. The present study used data from the first wave of the ‘Growing Up in Ireland’ 9-year-old cohort and employed structural equation modelling to assess the explanatory value of a model informed by previous research findings. Goodness-of-fit indices indicated that many aspects of the familial environment of Irish teenage families did indeed place children at a substantial risk of problematic developmental outcomes. In particular, the results implicated the influential power of economic stability and familial conflict on the well-being of teenage families and related child outcomes, results similar to those reported in international studies.

Previous research has tended to classify stepfamilies based on self-report of their familial relationships. However, some stepfamily members do not identify as being part of a stepfamily, leading to the exclusion of certain stepfamilies from stepfamily research. Using data from the first national cohort study of children in Ireland, the aim of this study was to compare the characteristics of self-identifying stepfamilies with those of non-self-identifying stepfamilies, a group about which little is known. The analysis revealed that in approximately 10% of stepfamilies, neither parent declared their stepfamily status (n = 34, N = 288 stepfamilies). No differences emerged between self-identifying and non-self-identifying stepfamilies in the quality of the parent–child or spousal relationships. Non-self-identifying stepfamilies were less likely to be complex, and were more likely to be stepmother and simple stepfamilies than self-identifying stepfamilies. These findings suggest that non-self-identifying stepfamilies constitute a significant minority of stepfamilies who may exhibit unique structural characteristics.

Psychotic experiences (PEs) are common in early adolescence and are associated with nonpsychotic psychopathology. However, not all adolescents with PEs have subsequent psychopathology, and vice versa. To date, factors mediating the relationship between PEs and psychopathology have been understudied. The aims of this study were to investigate the bidirectional relationship between PEs and psychopathology in adolescence and to investigate potentially malleable mediators of these relationships. Data from 2 waves (age 13 and 17 years) of Cohort ’98 of the Growing Up in Ireland study were examined (n = 6,206). Using KHB pathway decomposition, we investigated the following as potential mediators of the relationship between psychopathology and PEs: parent-child relationship (conflict and positive), self-concept, and child-peer relationship (alienation and trust). Supplementary counterfactual mediation and sensitivity analyses were conducted. Early adolescents with psychopathology had twofold increased odds of late adolescent PEs (internalizing problems: odds ratio [OR] = 2.03, 95% confidence interval [CI; 1.56, 2.62]; externalizing problems: OR = 1.99, CI [1.51, 2.60]). Parent-child conflict explained between 23% and 34% of the associations between internalizing and externalizing problems and subsequent PEs. Early adolescents with PEs had increased odds of late adolescent psychopathology (internalizing problems: OR = 2.01, CI [1.61, 2.50]; externalizing problems: OR = 1.70, CI [1.25, 2.31]). Self-concept alone accounted for 52% of the relationship between PEs and subsequent internalizing problems. There is a bidirectional heterotypic relationship between psychopathology and PEs. Parent-child conflict and self-concept are important characteristics that mediate a proportion of the relationship between PEs and psychopathology. Interventions targeting parent-child conflict in the context of psychopathology and self-concept in the context of PEs may assist in reducing the incidence of poorer outcomes.

Reflecting the neglect of childhood disability in social stratification research, there is a notable dearth of research on the mechanisms underpinning disability differentials in educational outcomes. Drawing on rich longitudinal data collected at 9, 13 and 17 years as part of Ireland’s ‘Growing Up in Ireland’ study, we look at the impact of special educational needs (SEN) identification in primary school on upper secondary outcomes. A bioecological framework and the Process–Person–Context–Time model allow us to understand how interactions with family, teachers, friends and school—as proximal processes—relate to early school leaving and post-school planned pathways after accounting for personal and context characteristics. Overall, young people identified at age 9 as having SEN are at increased risk of early school leaving and are more likely to plan to attend further education and training, rather than higher education. However, after accounting for proximal processes and personal and context variables, students identified at age 9 as having SEN are no longer distinct in terms of secondary attainment and post-school planning. Instead, these young people are more likely to experience forms of vulnerability that are important in shaping these outcomes. These key educational outcomes are strongly shaped by family and school-related factors—both proximal processes and context characteristics—suggesting that efforts to support retention and pathway planning should be underpinned by an ecological understanding of young people’s trajectories and the cumulative disadvantages they face.

Key insights

What is the main issue that the paper addresses?

Using a bioecological framework and Growing Up in Ireland data, this paper explores early school leaving and post-school plans among young adults identified in primary school as having special educational needs (SEN). This is a key topic, as young people with SEN are at greater risk of early school leaving and less likely to attend higher education.

What are the main insights that the paper provides?

As a group, young people identified in primary school as having SEN are more likely to experience economic vulnerability and to attend schools with a socioeconomically vulnerable profile. After accounting for these and other key personal and contextual characteristics, childhood SEN status is no longer a significant factor in early school leaving or post-school plans.

Self-harm in adolescents and young adults (AYAs) is the result of a complex interaction of biological, psychiatric, psychological, social, and cultural risk factors. A lot of research has already been conducted to identify the risk factors for self-harm in AYAs. On the other hand, there has been less research conducted on the simultaneous effects of, and the interactions between, multiple risk factors for self-harm in heterogeneous AYA individuals. In this study, we conducted a latent class analysis (LCA) of three waves from the Growing Up in Ireland (GUI) longitudinal cohort study at ages 13, 17 and 20 to identify homogenous subgroups of AYA individuals who exhibit similar risk markers for self-harm at these three time points. Then, we evaluated the risk that these subgroups ever self-harmed by age 17, self-harmed at age 20, or were persistently self-harming across both time points. The most at-risk group appeared to be the individuals aged 17 who had been diagnosed with depression/anxiety. Compared to the low-risk-marker group, the ‘diagnosed with depression/anxiety’ group had a 30-fold risk of self-harm at age 17, and 32-fold risk of persistently self-harming by age 20. The ‘undiagnosed but high depression’ group at this time point was also at significant risk of self-harm. This research enables us to understand which risk markers tend to co-occur together and will help to identify high-risk groups for self-harm both clinically and in the community. An investigation of risk markers like this can potentially be used in the design of public health interventions to reduce the burden of self-harm, and indeed suicide, in young people.

Key messages

• We identified sub-groups of young people with a high-risk of self-harm and suicide from the general population.

• These identifiable sub-groups can inform intervention policies and strategies for prevention programmes both in clinical and non-clinical settings like schools.

Several approaches frame childbirth as an event that can reduce partnership quality, generate work-family conflicts, intensify financial pressures, and increase separation risk. The present study discusses theories of separation in relation to pregnancy intentions leading to a birth and analyses data from Growing Up in Ireland. Transition rate models of parental separation nine months to five years after childbirth show higher risks of separation after pregnancies described as “somewhat too early”, “much too early” and after “unwanted” pregnancies. These differences are due partly to sociodemographic factors that influence unplanned pregnancies and subsequent separation. Increases in workfamily conflicts after birth do not increase separation risk.

Sociologists of childhood have stressed the importance of children’s experience in the present and children as agents who actively construct their own lives and influence relationships with family and friends. Current thinking in the field of child well-being emphasises the need to consult children as experts in their own lives. Findings from research with children have led to important insights about what contributes to well-being. Relationships with family and friends have been found to be central to well-being whilst bullying by peers deeply impacts on their well-being. Shared activities appear to be the context for children to not only master competences but also learn about and negotiate relationships. The Growing Up in Ireland interviews with 9 year old children were re-analysed with a view to exploring these crucial domains and how they impact on the children’s well-being. The children were found to have a wide circle of family connections and were particularly close to their mothers although also close to their fathers. Grandparents played a significant role in their lives and their relationships with siblings were often positive but did fluctuate. Reasons for closeness centred around trust. Lack of availability due to work was a key contributor to children feeling less close to a family member. The children were involved in a wide range of structured activities after school and at the weekend, This was usually balanced with free time although some ‘hurried’ children had frenetic lifestyles. Involvement in unstructured activities such as free play was particularly associated with time with friends and choice. Friendship was characterised by sharing and trust. On the other hand, bullying by peers had been experienced by many of the children and almost all were conscious of the danger of becoming bullied. The wider issues of work-family balance and its impact on children, the predominance of bullying and children’s right to be heard are reflected upon.

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.

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.

The aim of this paper is to quantify the effect of economic, parental and lifestyle factors on the psychological health of children at significant points in recent economic history in Ireland. The paper uses data from the Growing Up in Ireland study and employs a dynamic random effects ordered logistic regression model to test the magnitude of these effects. The results indicate that proxy income variables, such as ability to make ends meet and homeownership, are relevant in predicting child psychological health outcomes. Equally important are intergenerational health associations between the mother and the psychological health of children.

The aim of this study was to examine the role of different types of home learning activities, such as reading, singing, painting, playing games, and letters and numbers (ABCs and 123 s), in the development of nonverbal reasoning skills in young children. Although much previous research has focused on the role of the home learning environment in the development of language and numeracy skills, few studies have explored other aspects of cognitive development such as nonverbal reasoning. The data were drawn from the Growing Up in Ireland study, a nationally representative longitudinal birth cohort study. We examined whether learning activities were associated with scores on standardized nonverbal reasoning and vocabulary tests of the British Ability Scales in a sample of 9793 3-year-old children. The regression models also controlled for other factors that potentially influence cognitive development such as the parent–child relationship and maternal education. The findings indicate that activities such as reading, games, and painting/drawing have a small but statistically significant association with nonverbal reasoning scores, as well as with vocabulary scores, even after controlling for other factors in the model. Teaching the alphabet or numbers did not make significant contributions to the model. The findings of the study highlight the importance of considering the role of different types of home learning activities, as well as other environmental factors, in different aspects of cognitive development. We consider the implications of the findings for theories of cognitive development and for supporting cognitive development in young children.

The aim of this study was to identify, using cluster analysis, novel sleep phenotypes in a population based cohort of infants, and to explore the associations between infant sleep profiles and their mothers’ health and well-being. 11,134 mothers of 9-month old infants were interviewed as part of the Growing Up in Ireland National Longitudinal study and reported on their health and infant’s sleep patterns. 16 infant sleep variables were recorded together with measures of parental stress, depression, health and well-being. Multiple iterations of a two-step hierarchical cluster analysis were carried out to identify the optimum number of clusters and the subset of parental-reported sleep variables required to identify distinct sleep profiles. Four distinct sleep profiles were identified based on the following variables; (1) infant sleep duration at night, (2) parental sleep duration, (3) does baby wake during night (yes, no)? (4) Usual sleep location for most of the night and, (5) parental reporting of problem infant sleep patterns. This identified two less favorable profiles with both infants and mothers sleeping less and where mothers are more likely to report their infants’ sleep patterns as problematic. Mothers of infants belonging to these sleep profiles were more likely to have higher levels of stress, depressive symptoms, and poorer self-reported health than other sleep profiles. Breastfeeding was associated with both groups and rates were highest in a group of infants that were more likely to co-sleep with their parents and have diverse ethnic backgrounds. This study demonstrates, for the first time, two infant sleep profiles with distinct phenotypical frameworks that are significantly associated with maternal stress, depression, and poorer self-report of health.

The COVID-19 lockdown and closure of schools, clinics, and community-based services put children with autism spectrum disorders (ASDs) and other developmental disabilities (DDs) at increased risk of negative outcomes. This study aimed to investigate parents’ perceptions of their children’s behavioural outcomes during the COVID-19 lockdown, parents’ satisfaction with services during this time, and willingness to engage in telehealth. A cross-sectional study was conducted in Ireland. Parents (n = 89) completed an online questionnaire that included the strengths and difficulties questionnaire (SDQ-P). Results demonstrated that children with ASD/DDs were vulnerable to negative outcomes including hyperactivity, emotional symptoms, problems with peers and fewer prosocial behaviors. Children’s behavioral outcomes (‘current sample’, n = 89) were also compared with pre-COVID-19 data taken from the Growing Up in Ireland Study (‘GUI sample’, n = 327). The current sample exhibited significantly more behavioral difficulties than the pre-COVID GUI sample (p < 0.001). For the current sample, scores on each of the five SDQ subscales were significantly associated with a total impact score, and parents reported dissatisfaction with support services provided and willingness to engage in behavioral telehealth. Commitment is required to identify barriers to services faced by families in Ireland and to address the need for adapted behavior support services during periods of emergency.

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.

The Growing Up Healthy in Families Across the Globe project is an international collaboration examining the potential for harmonised analysis using five longitudinal studies (from New Zealand, Ireland and Scotland). All five studies follow the lives of children, are interested in the dynamics of family change and work to inform policy to potentially improve population well-being across the life-course. Comparative analysis from harmonised longitudinal studies, where change over time is emphasised, provides a unique view to determine how and why environments change, which environments are supportive and which are not. This paper discusses the challenges and tasks involved when preparing and conducting harmonised analysis, and initial findings from the Growing Up Healthy project are discussed. The studies were, from New Zealand, Te Hoe Nuku Roa, the Pacific Island Families Study and Growing Up in New Zealand, and from Scotland and Ireland Growing Up in Scotland and Growing Up in Ireland. Post hoc data harmonisation of measures resulted in the identification of several closely aligned variables. The harmonised descriptive variables from the five studies highlight many similarities across the studies. A risk factor model to predict child development outcomes (using the Strengths and Difficulties Questionnaire) was developed and resulted in very similar patterns of risk in New Zealand, Ireland and Scotland. Risks included: maternal relationship status, maternal education, smoking in pregnancy, maternal self-reported health and maternal long-standing illness. The insights will be of interest to all those concerned with child development in contemporary New Zealand, Ireland, Scotland and other similar countries.

The Growing Up in Ireland Infant Cohort dataset (n = 11,134) includes information on fertility treatments for over 400 infants. IVF (28.1 %) and IVF-related treatments (17.8 %) were the most frequent, but there was also a high percentage following clomiphene citrate alone (31.5 %). Infants born following fertility treatment were much more likely to be in higher income families, and this relationship was not accounted for by older mothers in wealthier families. Analysis of fertility-treatment pregnancies among Irish infants, controlling for income and maternal age, shows a greater risk of multiple birth and low birth-weight, although the latter appears to be largely related to the former especially for IVF-type treatments.

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.
