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

To describe response rates and characteristics associated with response to the Pregnancy Risk Assessment Monitoring System study in Ireland (PRAMS Ireland). Using hospital discharge records of live births at a large, urban, obstetric hospital, a sampling frame of approximately 2,400 mother-infant pairs were used to alternately sample 1,200 women. Mothers’ information including name, address, parity, age and infant characteristics such as sex and gestational age at delivery were extracted from records. Modes of contact included an invitation letter with option to opt out of the study, three mail surveys, a reminder letter and text message reminder for remaining non-respondents. Sixty-one per cent of women responded to the PRAMS Ireland survey over a 133 day response period. Women aged <30, single women, multiparous women and women with a preterm delivery were less likely to respond. Women participating in PRAMS Ireland were similar to the national birth profile in 2011 which had a mean age of 32, were 40 % primiparous, 33 % single or never married and had a 28 % caesarean section rate. Survey and protocol changes are required to increase response rates above recommended Centers for Disease Control and Prevention (CDC) thresholds of 65 % within the recommended 90 day data collection cycle. Additional efforts such as stratification and over-sampling are required to increase representativeness among hard to reach groups such as younger, single and multiparous women before expanding the project to an ongoing, national surveillance system in Ireland.

Gender inequality in housework divisions is persistent. This study examined early-emerging patterns in gender roles via children’s gendered housework time in the Irish context using time-use diary and questionnaire data, controlling for key demographic variables. This study utilized longitudinal “Growing up in Ireland” data, comparing the same children’s behaviour at age 9 and 13. Participants were a nationally representative, weighted sample of school going children living in Ireland, including 4,135 girls, 3,831 boys and their caregivers. The results highlight that inequalities in domestic chores occur at nine and are even greater at 13: girls do more housework and children tend to do “gender typical” chores. Consequences are discussed in relation to gender inequality and policy implications.

A small minority of Irish students attend fee-charging second-level schools. However, media analyses of the backgrounds of those students who go on to more sought-after tertiary educational institutions or degree courses suggest that a disproportionate number of them were attendees at fee-charging schools. There are a few reasons why this might be the case. In this analysis, the longitudinal data points of the Growing Up in Ireland (GUI) study are exploited to weigh up the evidence behind differing explanations. An estimated measure of Leaving Certificate success was generated for 3105 participants in wave 4 of the GUI. From waves 1 and 2, the ability of those participants was calculated based on their performance in several standardised tests taken prior to attending second-level school. The analysis found that while the students who attended fee-charging schools were about 9% ahead in Leaving Certificate performance, they had roughly the same lead in measured ability on entry into the second-level schools. The analysis found a significant but marginal positive effect on attending private schools. This result is in line with the general international findings. Ireland’s hybrid funding structure for fee-paying schools is discussed. Gender and household income effects were noted.

Background
Poverty is associated with poor outcomes, yet exposure to distinct poverty trajectories in early childhood is not well understood.

Objective
To understand the prevalence of different trajectories of household poverty and their association with mid-childhood and mother indicators of physical health and psychopathology in Ireland.

Methods
We used a nationally representative, prospective cohort (Growing Up in Ireland–Infant Cohort). Household poverty included lowest third income decile, subjective poverty and material deprivation when children were aged 9 months, and 3, 5, 9 years. We used group-based multitrajectory cluster modelling to classify trajectories of poverty. Using multivariable logistic regression, adjusted with separate child and mother confounders, we assessed the association of poverty trajectories from 9 months to 9 years with child outcomes (overweight, any longstanding illness and psychopathology) at age 9 years and the same poverty trajectories over the same 9-year period with mother outcomes (overweight, any longstanding illness and depression).

Results
Of 11 134 participants, 4 trajectories were identified: never in poverty (43.1%), material/subjective>monetary poverty (16.1%), monetary>material poverty (25.6%) and persistent poverty (15.2%). Children in persistent poverty compared with those in never in poverty experienced higher odds of being overweight at 9 years (adjusted OR (aOR) 1.70, 95% CI 1.34, 2.16), having a longstanding illness (aOR 1.51, 95% CI 1.20, 1.91), and psychopathology (aOR 2.06, 95% CI 1.42, 2.99). The outcomes for primary parents (99.7% were mothers) were as follows: having higher odds of being overweight (aOR 1.49, 95% CI 1.16, 1.92), having a longstanding illness (aOR 2.13, 95% CI 1.63, 2.79), and depression (aOR 3.54, 95% CI 2.54, 4.94).

Conclusions
Any poverty trajectory was associated with poorer psychopathology and physical well-being in late childhood for children and their mothers in Ireland.

Background
Poverty is associated with poor outcomes, yet exposure to distinct poverty trajectories in early childhood is not well understood.

Objective
To understand the prevalence of different trajectories of household poverty and their association with mid-childhood and primary-parent(mother) indicators of physical health and psychopathology in Ireland.

Methods
We used a nationally representative, prospective cohort (Growing-up-in-Ireland– Infant-Cohort). Household poverty included lowest third income decile, subjective poverty and material deprivation when children were aged 9-months(m),3,5,9-years(y). We used group based multi-trajectory-cluster-modelling to classify trajectories of poverty. Using multivariate logistic regression, adjusted with separate child and mother confounders, we assessed the association of poverty trajectories from 9m to 9y with child outcomes (overweight, any longstanding illness and psychopathology) at age 9y and the same poverty trajectories over the same 9y period with mother outcomes (overweight, any longstanding illness and depression).

Results
Of 11,134 participants, four trajectories were identified: never-in-poverty (43.1%), material/subjective>monetary-poverty (16.1%), monetary>material-poverty (25.6%), and persistent-poverty (15.2%). Children in persistent-poverty compared with never in poverty experienced higher odds of being overweight at 9y (adjusted odds ratio aOR 1.70,95% CI 1.34, 2.16), having a longstanding illness (aOR 1.51,95% CI 1.20, 1.91) and psychopathology (aOR 2.06,95% CI 1.42, 2.99). The outcomes for primary parent (99.7% were mothers) had higher odds of being overweight (aOR 1.49,95% CI 1.16, 1.92), having a longstanding illness (aOR 2.13,95% CI 1.63, 2.79), and depression (aOR 3.54,95% CI 2.54, 4.94).

Conclusions
Any poverty trajectory was associated with poorer psychopathology and physical wellbeing in late childhood for children and their mothers in Ireland.

What is already known on this subject?
Poverty is understood as having both objective (e.g. low household income) and subjective dimensions (e.g., perception of being poor relative to others, poverty related anxiety). Evidence highlights the association between child poverty exposure and child and mother wellbeing outcomes.

What this study adds?
Our study examined predicted trajectories of multi-dimensional poverty and child and mother outcomes using a large national cohort. We identified that any poverty trajectory in childhood had a higher odds of being associated with poor well-being outcomes.

How this study might affect research, practice or policy?
This study highlights the need for strategies to ameliorate any poverty exposure as all poverty trajectories resulted in poorer wellbeing outcomes. Strategies should be considered to ameliorate any poverty exposure in early childhood (e.g., school based resourcing).

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, following 8,568 children from nine to 20 years, we examine how different MH difficulties, and 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, and if voting, are more likely to vote for an anti-establishment party. Adolescents with chronic emotional MH difficulties starting in childhood report a higher likelihood of voting for an anti-establishment party, but also show a higher probability of political activism and low 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.

Objectives
Maternal health behaviours (MHBs) can influence pregnancy outcomes. Despite efforts internationally to encourage positive MHBs, women often fail to comply with pregnancy guidelines. International studies show differences in MHBs between nationalities and an effect of time spent in the host country. There is limited Irish data in this area, with no previous research relating to the effect of time in Ireland.

Study design
This study is a cross-sectional analysis of the Growing Up in Ireland infant cohort, a nationally representative longitudinal study.

Methods
Examination of the MHBs of non-Irish nationals during pregnancy and the effect of time in Ireland on the said behaviours.

Results
An association was found between time spent in Ireland and increased alcohol consumption prevalence. Those living in Ireland for ≤5 years were 60.8% less likely to consume alcohol during pregnancy (0.000) and 29.3% less likely to take folic acid before conception (0.021). Those who smoked during pregnancy were 98.6% more likely to consume alcohol (0.000) and those who consumed alcohol were 95.2% more likely to smoke during pregnancy (0.000).

Conclusions
The results demonstrate differences in MHBs and the influence of time living in Ireland. These findings are of relevance for policy and intervention planning to optimise pregnancy outcomes among non-nationals.

Background
The use of dietary quality scores/indices to describe diet quality in children has increased in the past decade. However, to date, few studies have focused on the use of these scores on disease outcomes such as childhood obesity and most are developed from detailed dietary assessments. Therefore, the aims of this study were: firstly to construct a diet quality score (DQS) from a brief dietary assessment tool; secondly to examine the association between diet quality and childhood overweight or obesity; thirdly we also aim to examine the associations between individual DQS components and childhood overweight or obesity.

Methods
A secondary analysis of cross sectional data of a sample of 8,568 9-year-old children and their families as part of the Growing Up in Ireland (GUI) study. Subjects were drawn from a probability proportionate to size sampling of primary schools throughout Ireland over the school year 2007–2008. Height and weight were measured by trained researchers using standardised methods and BMI was classified using the International Obesity Taskforce cut-points. The DQS (un-weighted) was developed using a 20-item, parent reported, food frequency questionnaire of foods consumed over the past 24 h. Adjusted odds ratios for overweight and obesity were examined by DQS quintile, using the first quintile (highest diet quality) as the reference category.

Results
The prevalence of normal weight, overweight and obese was 75, 19 and 6 % respectively. DQS ranged from -5 to 25, higher scores indicated higher diet quality in the continuous score. In analyses adjusted for gender, parent’s education, physical activity and T.V. viewing, child obesity but not overweight was significantly associated with poor diet quality: OR of 1.56 (95 % CI 1.02 2.38) in the 5th compared to the 1st DQS quintile. Findings from individual food items were inconsistent.

Conclusions
The findings suggest that diet quality may be an important factor in childhood obesity. A simple DQS developed from a short dietary assessment tool is significantly associated with childhood obesity.

Parent-child interactions are influenced by factors outside the immediate family. A recent paper † based on data from the Growing Up in Ireland study (GUI) focuses in particular on the support provided by grandparents in caring for very young children. Such support can have important direct and indirect influences on child development. For example, a grandparent who babysits a young child while parents have a night out has a direct interaction with the child in the context of providing care. However, there is also an indirect influence in the context of supporting the mother-father relationship which, in turn, could be expected to affect (positively) parental interactions with the child.

The transition to parenthood and early infancy have been identified in the literature as the critical periods requiring most support. Infancy is a particularly intensive parenting period. Children at this stage remain highly dependent on caregivers for their basic needs but, by 9 months (the age of infants at the time of data collection in the GUI study), they are also starting to become more mobile and interaction-seeking. In the Irish context, 9 months may also be the stage when mothers may be contemplating a return to work or education following maternity leave (paid and unpaid) – and those who have been breastfeeding will likely have finished at least exclusive breastfeeding.

Here we report some key results from the paper; further detail, and a full set of references to the literature can be found in the paper itself.

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.

None of the many critical moments in Ireland’s often tumultuous history was more significant or defining than the Easter Rising of 1916. Central to the Rising was the Proclamation of Independence, in which Pádraig Pearse declared the new nation’s resolve to cherish all its children equally. CHERISHING ALL THE CHILDREN EQUALLY? brings together contributions from a range of disciplines to shed light on the processes of child development and to investigate how that development is influenced by a variety of demographic, family and socio-economic factors. Making extensive use of research and data that have emerged over recent years from the Growing Up in Ireland longitudinal study of children, the book considers whether or not all children can participate fully and equitably in contemporary Irish society. It asks whether or not we do, in fact, cherish all our children equally in modern Ireland, regardless of their family circumstances, health or ethnic background.

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.

Aim
To explore the association between weight and bullying; considering victims and perpetrators as two aspects of bullying, and subjective perception and objective measurement as two aspects of weight.

Methods
This study is based on the first wave of data collection from Growing Up in Ireland – the National Longitudinal Study of Children. The two-stage sample design included a sample of 910 primary schools in Ireland, from which a sample of 8568 nine-year-old children and their families was randomly selected. Analysis is based on statistically reweighted data to ensure that it is representative of all 9-year-olds in Ireland.

Results
Significantly (P < 0.001) more girls were overweight or obese (33.1%: 23.1% overweight and 10% obese) than boys (25.2%: 18.3% and 6.9%). Children who were body mass index (BMI) classified as overweight or obese were significantly (P < 0.001) more likely to be victimised when compared with children whose BMI was not classified as overweight or obese. BMI-classified thinness was not significantly associated with victimisation; however, the body image of being skinny or very skinny was significantly (P = 0.015) associated with being victimised. Bullying perpetration was not associated with BMI-derived weight classification but was significantly (P < 0.001) associated with the child’s own self-description of weight.

Conclusions
Overall body image was found to have a stronger association with victimisation and bullying perpetration than objective BMI-derived weight classification. Further research investigating the mediating role of body image in the relationship between weight, victimisation and bullying is necessary to better understand this association.

Objective
Childhood chronic illness can have a high impact on the child’s quality of life. The foundations of health are established in early life, and are shaped by biological, psychosocial, spiritual and environmental processes and influences. The objectives of this presentation are twofold: firstly to describe the prevalence of chronic illness in 9-year-olds in Ireland, secondly to illustrate how chronic illness influences the psychological and social development of the children.

Methods
Analysis was based on data of 8570 9-year old children, and their families who participated in Growing Up in Ireland—the National Longitudinal Study of Children. The sample was generated through the primary school system. A representative sample of 910 schools participated; the sample of children and their families was randomly selected from within the schools. Questionnaires were administered in schools; and after completion of this phase, the project interviewers visited the families of the 9-year olds in their homes and administered core questionnaires to the Study Child and his/her carers who provided either home-based or centre-based care on a regular basis.

Results
The overall prevalence of chronic illness reported by mothers among the 9-year old cohort was 11% (gender-specific prevalence for boys: 13%, and significantly lower for girls: 10%). Respiratory illnesses accounted for almost half (46%) of all chronic illnesses, followed by mental and behavioural conditions with 19% (high gender dysbalance: reported for boys in 24%, for girls in 12%). Children with a reported chronic illness had significantly more emotional, conduct, hyperactivity, peer-based and prosocial difficulties when compared with children without a reported chronic illness. Abnormal scores, based on the Strengths and Difficulties Questionnaire were found in 20% in children with a chronic disease, and in 5.5% in children without a chronic disease. Socio-economic Status was associated with poorer health outcomes. Furthermore, primary care givers’ views and perceptions regarding the chronic illness of the child were found to be a significant factor on child strengths and difficulties in a multivariate model.

Conclusions
The majority of 9-year old children can be assessed as healthy. The most common chronic illness in this large cohort was respiratory disease and overall, chronic conditions were found to have a negative impact on the child’s emotional and social state.

Background
Preventing child mental health problems and child obesity have been recognized as public health priorities. The aim of the present study was to examine whether being breastfed (at all or exclusively) in infancy was a predictor of mental well-being and protective against risk of obesity at age 9.

Methods
Cross-sectional data from a large, nationally representative cohort study in the Republic of Ireland was used (n = 8357). Data on breastfeeding were retrospectively recalled. Child mental well-being was assessed using a parent-completed Strengths and Difficulties Questionnaire (SDQ). Child’s height and weight were measured using scientifically calibrated instruments.

Results
Logistic regression analyses indicated that, after controlling for a wide range of potential confounding variables, being breastfed in infancy was associated with a 26% (P < 0.05) reduction in the risk of an abnormal SDQ score at 9 years. Being breastfed remained a significant predictor of child mental well-being when child obesity was controlled for, indicating that being breastfed, independent of child obesity, is a predictor of child mental well-being. The results of a second logistic regression indicated that, after controlling for a wide range of potential confounding variables, being breastfed for between 11 and 25 weeks was associated with a 36% (P < 0.05) reduction in the risk of obesity at 9 years, while being breastfed for 26 weeks or longer was associated with a 48% (P < 0.01) reduction in the risk of obesity at 9 years.

Conclusions
Breastfeeding in infancy may protect against both poor mental well-being and obesity in childhood.
