A poor quality diet may be a common risk factor for both obesity and dental problems such as caries. The aim of this paper is to use classification tree analysis (CTA) to identify predictors of dental problems in a nationally representative cohort of Irish pre-school children. CTA was used to classify variables and describe interactions between multiple variables including socio-demographics, dietary intake, health-related behaviour, body mass index (BMI) and a dental problem. Data were derived from the second (2010/2011) wave of the ‘Growing Up in Ireland’ study (GUI) infant cohort at 3 years, n = 9793. The prevalence of dental problems was 5.0% (n = 493). The CTA model showed a sensitivity of 67% and specificity of 58.5% and overall correctly classified 59% of children. Ethnicity was the most significant predictor of dental problems followed by longstanding illness or disability, mother’s BMI and household income. The highest prevalence of dental problems was among children who were obese or underweight with a longstanding illness and an overweight mother. Frequency of intake of some foods showed interactions with the target variable. Results from this research highlight the interconnectedness of weight status, dental problems and general health and reinforce the importance of adopting a common risk factor approach when dealing with prevention of these diseases.

Young children born preterm may be more affected by environmental influences than their full-term peers. Few studies have investigated whether such effects exist for older children and young adolescents. With participants aged 9 and 13 years, we examine whether children born preterm could be differentially affected by the quality of their relationship with their mothers and fathers. We used the Growing Up in Ireland dataset: a longitudinal sample of 8,568 children in Ireland (51.4% female, 48.6% male) and their parents. We found that parent–child conflict was consistently associated with poorer verbal, numerical, and socioemotional outcomes; in some instances, parent–child closeness was associated with better outcomes. Being born very preterm was consistently associated with negative outcomes. We found support for a diathesis-stress model of preterm birth in just one instance: children born very preterm displayed a stronger relationship between maternal conflict and increased socioemotional difficulties.

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.

Multiple factors including the child’s non-linguistic characteristics and caregiving environment can affect language development. Since preterm birth (<37 weeks’ gestation) can negatively affect language development, this study used path analysis to investigate whether the influence of preterm birth on expressive language development at 3 and 5 years of age is mediated by a child’s non-linguistic characteristics (temperament and cognitive, motor, and social-personal abilities), caregiving environment (maternal and paternal stress and depression, mother-child and father-child relationship quality), and interactions between these domains. These analyses were conducted using three waves of data (ages: 9 months, 3 years, 5 years) on 8,712 children (4,300 female; 535 preterm) from a nationally-representative longitudinal study in Ireland. Preterm birth was indirectly (but not directly) associated with expressive language at 3 years of age via cognitive and social-personal abilities (but not motor abilities, mother-child relationship quality, or father-child relationship quality) at 9 months. There was no direct or indirect effect of preterm birth on expressive language at 5 years of age. Preterm birth negatively affected mother-child and father-child relationship quality at 3 years via fussy-difficult temperament and mother’s/father’s stress (but not depression) at 9 months. These findings are discussed with reference to international standards for neonatal care, including the need for long-term developmental monitoring of children born preterm by multidisciplinary healthcare teams, alongside parental supports promoting mental health and confidence in caregiving tasks. Future study recommendations are made to expand the tested models in line with family systems perspectives.

It is well-established that participation in shared book reading interactions with caregivers supports children’s early language and literacy development. Most of this literature focuses on reading experiences during the preschool period. Less is known about the nature and importance of such practices during infancy. Therefore, the goal of this study was to examine literacy practices between parents and infants in a large cohort study, Growing Up in Ireland. Interview, survey, and direct measurements of children’s language skills were used to examine whether parent-report of book reading practices when children were 9-months predicted child expressive vocabulary at 36-months (N = 9171). Regression analysis indicated that approximately 80% of 9-month-old Irish children are read to by parents. Characteristics of families who were more likely to report reading with children emerged: those with higher educational attainment, fewer depressive symptoms, and those who report a high-quality home language environment (e.g., reported talking more to children during everyday activities). Furthermore, children who were read to at 9-months had stronger expressive vocabulary skills at 36-months, even after accounting for socio-demographic and home literacy environment covariates measured at both 9- and 36-months. Results are discussed using a bioecological framework to describe how proximal and distal factors in the child’s environment converge to impact early childhood literacy development.

Introduction
The COVID-19 pandemic wrought acute harm to mental wellbeing across the globe; not least through its impact on morbidity and mortality, but also from health anxieties, lockdowns and their economic fallout, the closure of key services, as well as the disruption of social networks. However, while the pandemic’s onset was global, not everyone experienced the same harm to their mental health. This study draws on information on the mothers of 12-year-olds from the Growing Up in Ireland (GUI) study to look at what helped cushion the negative impact of the pandemic on their mental health.

Data and Methods
The study draws on GUI data on Cohort ’08, a nationally representative sample of children born 2007-2008 along with their caregivers. In December 2020, the GUI team conducted a survey of primary caregivers (98 per cent of whom are mothers) during the COVID-19 pandemic. Mothers’ mental health is captured using the Short-form Center for Epidemiological Studies Depression Scale (CES-D), with higher scores indicating a greater risk of depression. The longitudinal nature of GUI means we can compare measures of mothers’ mental health during the COVID-19 pandemic (December 2020) with two previous timepoints before the pandemic – wave 3 (2013/2014) and wave 5 (2017/2018) – to see whether trends in depression changed significantly over the pandemic.

The study looks at four sets of factors: (1) mothers’ social resources, such as the level of social cohesion in their neighbourhood (e.g., trust and reciprocity among neighbours) or the support they receive from friends/family; (2) their economic resources, such as the share of income received from welfare, or how difficult they feel it is to ‘make ends meet’; (3) the quality of mothers’ local environment, such as the degree of traffic problems; and (4) their religiosity, such as how often they attend church. All of these factors are measured prior to the onset of the pandemic to reflect the resources mothers had at their disposal going into the crisis.

To understand how these buffering factors may have cushioned mothers’ mental health, the study uses a set of measures on what experiences mothers had during the pandemic. These include whether they found supervising their child’s schoolwork stressful, whether they experienced a loss of income/employment, or whether they had COVID or were anxious about friends/family contracting it.

Results

What factors cushioned the impact of the pandemic on mothers’ mental health?

In the years prior to the pandemic (2013/2014 to 2017/2018), levels of depression among mothers remained relatively low and stable. However, depression scores among mothers rose steeply with the onset of the pandemic (compared to 2017/18), nearly doubling. Yet, not all mothers experienced an equal increase in depression scores.

Stronger economic resources, and better household conditions, played a protective role: depression scores rose less among mothers who reported being able to ‘financially make ends meet’ easily (compared to those who found it difficult) and among mothers who lived in less overcrowded housing. The local environments in which mothers were living also helped cushion their mental health. Mothers who lived in neighbourhoods where heavy traffic was not a problem, and those who lived in rural areas, saw their depression scores increase less over the pandemic, compared to mothers in more urban areas or where traffic was a major problem.

The strongest protective factors were mothers’ social resources and their religiosity. Mothers who, just before the pandemic, had a partner in the household and who felt they got the help they needed from friends and family saw their depression scores increase less over the pandemic. Those who reported living in more socially cohesive neighbourhoods (where neighbours trust each other, exchange favours, or feel more attached) – what are termed in the research literature as high social capital areas – were more strongly protected against depression during the pandemic. Symptoms of depression also increased much more steeply among mothers who never attended church before the pandemic compared to mothers who used to attend daily or weekly (even though in-person services had not resumed at the time of the survey).

How did these buffering factors protect mothers’ mental health?

Social resources cushioned mothers’ mental health because, during the pandemic, these mothers experienced better family relations and struggled less with care work, home schooling, and their children’s return to school. Economic resources supported mental wellbeing by reducing financial stresses, enabling better home/outdoor environments, and likely allowing families to purchase the tablets, laptops, and high-speed internet needed to engage in home schooling and working more easily. A better-quality local environment allowed mothers to spend more time outside and improved family relations. It was harder to explain the protective role of religiosity, but it may relate to greater optimism or a stronger sense of meaning in life that help protect people from the stress of adversity.

Conclusion and policy implications
This study finds strong evidence that the social, economic, religious, and environmental characteristics in people’s lives protect their mental health when experiencing adverse life events. While some of these characteristics are personal, others can be influenced by policy. Investment in local infrastructure to enhance access to green spaces and reduce neighbourhood disorder will pay dividends in supporting the mental wellbeing of women and their families. Furthermore, community development initiatives to foster a sense of local belonging and trust will enhance families’ capacity to weather crises. Integrating such perspectives into crisis management could help protect societies, particularly more vulnerable groups, and potentially weaken the well-documented long-term scarring effects that adverse life events have on people’s lives.

A large body of international literature has documented a correlation between nontraditional family structure and poorer child outcomes, yet researchers continue to disagree as to whether the association represents a true causal effect. This article extends this literature by employing propensity score matching using the first wave of data from the Growing up in Ireland child cohort study. We argue that the Irish case is of particular interest given the highly selective nature of non-marriage. We find that, on average, non-marriage has negative effects on a child educational development at age 9 but the effects are smaller in relation to health outcomes and the child’s self-concept. However, selection effects account for a non-trivial proportion of the differences in child outcomes across lone-mother and cohabiting families although hidden bias remains an important issue. This has important implications for policies which promote marriage as the key to child development as it appears that much of the benefits of marriage are not related to marriage per se but to the socio-economic background of mothers.

Participation in sporting, cultural and community activities can have significant emotional, physical and social benefits for children. A small literature now exists exploring the factors that promote or inhibit children’s participation in these activities. This paper adds to the literature using a large child-based dataset collected in Ireland, the Growing Up in Ireland dataset. The paper investigates the role of minority status as a barrier to child participation in a range of activities. Minority status in this paper is characterised as being non-Irish born, non-Roman Catholic, or having a family member in receipt of some form of social welfare. The association between such characteristics and child participation in sporting, cultural and community activities is examined using multivariate analyses. The results highlight that these factors are associated with lower participation in structured activities though the impact varies according to activity and minority grouping. The implications of the findings for policy 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.

In the literature on the links between socio-economic status (SES) and child health, there is evidence that the SES gradient is weaker for objective indicators of child health (e.g., height) than for subjective indicators (e.g., parental-assessed health). In this paper, we use crosssectional micro-data from the Growing Up in Ireland study to examine the SES gradient in height, weight, general health status and chronic illness incidence. Using household income and mother’s education as indicators of SES, we find only limited support for the contention that the SES gradient in child health in Ireland is stronger for more subjective indicators of child health.

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.

In this paper we make use of the first and second waves of the 2008 and 1998 cohorts of the Growing Up in Ireland study, to develop a multidimensional and dynamic approach to understanding the impact on families and children in Ireland of the Great Recession. Economic vulnerability is operationalised as involving a distinctive risk profile in relation to relative income, household joblessness and economic stress. We find that the recession was associated with a significant increase in levels of economic vulnerability and changing risk profiles involving a more prominent role for economic stress for both the 2008 and 1998 cohorts. The factors affecting vulnerability outcomes were broadly similar for both cohorts. Persistent economic vulnerability was significantly associated with lone parenthood, particularly for those with more than one child, lower levels of primary care giver (PCG) education and, to a lesser extent, younger age of PCG at child’s birth, number of children and a parent leaving or dying. Similar factors were associated with transient vulnerability in the first wave but the magnitude of the effects was significantly weaker particularly in relation to lone parenthood and level of education of the PCG. For entry into vulnerability the impact of these factors was again substantially weaker than for persistent and transient vulnerability indicating a significantly greater degree of socioeconomic heterogeneity among the group that became vulnerable during the recession. The findings raise policy and political problems that go beyond those associated with catering for groups that have tended to be characterized by high dependence on social welfare.

This paper examines mobility and changes in Body Mass Index (BMI) for a sample of Irish children/adolescents across three waves of the longitudinal Growing Up in Ireland dataset. Particular attention is paid to transitions across the key BMI thresholds of overweight and obesity. Analysis is carried out by gender and by maternal education. In general, mobility is observed, with intra-generational rank-rank BMI coefficients of around 0.63 compared to coefficients of around 0.77 for the mothers of the children over the same time period. Across the distribution as a whole there is relatively little variation by gender and maternal education. However there a gender difference in terms of mobility out of obesity with the Shorrocks mobility index across categories of normal weight/overweight/obesity taking a value of 0.56 for females as opposed to 0.71 for males. This relative lack of mobility is more observed in later rather than earlier adolescence.

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.

Using the first wave of the Growing Up in Ireland Survey of nine year old children we examine whether a teacher’s assessment of their pupil’s academic ability is influenced by the weight status of the child and/or the child’s mother. Multivariate regression analyses of the teacher’s assessment, controlling for the child’s actual test performance, their BMI, their mother’s BMI, other socio-demographic and teacher characteristics were undertaken. The study highlighted that child BMI was not a significant determinant but that children whose mother was obese were more likely to be rated as below average in reading and in maths compared to those whose mother was leaner, after adjusting for their measured ability. The potential for mother’s weight status to influence teachers’ assessments of their children’s perceived ability could have long term ramifications for educational outcomes and warrants further study.

Digital technologies have become an increasingly prominent feature of children’s lives both within and outside educational environments (McCoy, Quail, and Smyth 2012. Influences on 9-Year-Olds’ Learning: Home, School and Community. Dublin: Department of Children and Youth Affairs). Despite considerable media debate, we have little robust evidence on the impact of technology use on children’s development, both academically and socially. Much of the literature in this area relies on small-scale cross-sectional studies. Using longitudinal data on 8500 9-year-old children in Ireland, we examine the influence of early mobile phone ownership on children’s performance in reading and maths between 9 and 13 years of age. Across both reading and maths domains, children who already report owning a phone by the age of nine fare less well in terms of their academic development as they move into adolescence. The measured effects are sizeable, implying about 4 percentile lower ranking on standardised tests for an average student. Our results are consistent with the idea that there may be significant educational costs arising from early mobile phone use by children. Parents and policymakers should consider whether the benefits of phone availability for children are sufficiently large to justify such costs. We suggest a range of direct and indirect cognitive effects that could help explain these results.

Educational expectations and the way in which they shape actual outcomes act as an important vehicle for the intergenerational reproduction of social inequality. This article draws on rich information from the Growing Up in Ireland longitudinal study to explore the factors influencing the educational expectations of 13-year-old young people and their parents. The findings point to high levels of expectations among parents but one-third of young people are found to hold lower expectations than their parents. Both sets of expectations are shaped by parental education, social class and household income, though parental expectations are more strongly structured by social background than those of young people. The article seeks to contribute to the literature on educational expectations in three interrelated ways. Firstly, it focuses on a phase of schooling, the transition to secondary education, which represents a time of significant change in young people’s learning experiences, and transition difficulties are found to dampen their expectations. Secondly, the analyses unpack the extent to which signals from the school influence parental perspectives, with academic achievement, child attitudes to maths, ability group assignment and teacher reprimands emerging as significant drivers of parental views of their children’s potential. Thirdly, the analyses take account of both the primary and secondary school attended and indicate significant between-school differences in young people’s intentions to go on to higher education.

A growing number of international studies document the importance of regular school attendance. There is a consensus among authors that absenteeism has negative implications for academic achievement as well as the social development of the child and may put them at a disadvantage in terms of their position in the education and labour market. Most of the existing studies have focused on school absenteeism among adolescents with studies on poor school attendance among young children relatively rare. This paper addresses this gap in research by exploring factors that are related to school absenteeism in Irish primary schools. Drawing on a nationally representative study of nine-year-olds, it demonstrates the complexity of the issue. The findings indicate that a combination of institutional and individual factors shape patterns of poor school attendance in Irish primary schools. While the data relate to the Irish situation, the paper raises a number of issues of interest to an international audience.

Children, particularly those of preschool ages (below 3 years), spend the majority of time indoors in the family home. Home conditions can impact upon occupant’s health, with energy poverty identified as a public health concern in Europe and internationally. Children growing up in energy poor homes may be especially vulnerable to health impacts, though the area is relatively understudied. This study addresses a gap in understanding, examining the effect of household energy poverty on the health of resident children using longitudinal data from two cohorts – an Infant Cohort (aged 9 months to 5 years) and a Child Cohort (aged 9 years to 17–18 years), growing up in Ireland.

Panel logistic regression models adjust for a range of covariates including socioeconomic and household information as well as smoking in the household. For the Infant Cohort, household energy poverty was associated with a 1.41 times higher odds of child respiratory illness (p = 0.003; 95% Confidence Interval (CI) 1.12–1.77), and 1.47 times the odds of child wheezing (p < 0.001; 95% CI 1.25–1.74). The odds of a young child being rated as very healthy was lower (point estimate: 0.85, p = 0.011; 95% CI 0.75–0.96). For older children, the relationships were not statistically significant. The risk that energy poverty presents for the health of young children merits continued policy attention.
