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.

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.

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.

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.

This article explores the role that home-learning activities (HLAs) play in the relationship between social origin and cognitive development using an Irish birth cohort study, Growing Up in Ireland. Numerous studies using different measures of the home-learning environment (HLE) have shown that it has considerable influence on young children’s cognitive development, and that the HLE is often linked to social origin. We find a social gradient in vocabulary even at age 3 years, with the largest gaps for mothers’ education. Family income, mothers’ education, and social class are also associated with vocabulary independently, though these associations are reduced by adding all three measures simultaneously. The extent of HLAs helps explain a very small part of the education differences and none of the income or social class differences in vocabulary. We find some evidence that HLAs may be more salient for children from families with low income and lower social class backgrounds in terms of supporting vocabulary development, thereby compensating somewhat for disadvantage. HLAs also appear to encourage vocabulary development between age 3 and 5, and play a role in reducing the gap in vocabulary between high- and low-income children.

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.

This paper examines patterns of continuity and change in the texture, meanings and rhythms of family relationships between young (school-aged) children and their grandparents in Ireland, from the first half of the twentieth century through 2008, focusing on memories and contemporary experiences of grandparent/grandchild relationships from a ‘child’s eye’ perspective. The paper is based on a qualitative longitudinal analysis of two major datasets:
(1) Life Histories and Social Change, which consists principally of life history interviews with three twentieth century birth cohorts of Irish people and
(2) the Growing Up in Ireland Qualitative Study which consists of semistructured interviews with a sub-sample of children born at the turn of the twenty-first century (and their parents) in one of the two birth cohorts that form part of a prospective national panel study.

Importance As young people’s mental health difficulties increase, understanding risk and resilience factors under challenging circumstances becomes critical.

Objective To explore the outcomes of the COVID-19 pandemic on secondary school students’ mental health difficulties, as well as the associations with individual, family, friendship, and school characteristics.

Design, Setting, and Participants For this cohort study, follow-up data from the My Resilience in Adolescence (MYRIAD) cluster randomized clinical trial were collected across 2 representative UK cohorts. Mainstream UK secondary schools with a strategy and structure to deliver social-emotional learning, with an appointed head teacher, and that were not rated “inadequate” in their latest official inspection were recruited. A total of 5663 schools were approached, 532 showed interest, and 84 consented. Cohort 1 included 12 schools and 864 students, and cohort 2 included 72 schools and 6386 students. COVID-19 was declared a pandemic after cohort 1 had completed all assessments (September 2018 to January 2020), but cohort 2 had not (September 2019 to June 2021).

Exposures Cohort 2 was exposed to the COVID-19 pandemic, including 3 national lockdowns. Associations of individual, family, friendship, and school characteristics with students’ mental health were explored.

Main Outcomes and Measures Changes in students’ risk for depression (Center for Epidemiological Studies-Depression scale); social, emotional, and behavioral difficulties (Strengths and Difficulties Questionnaire); and mental well-being (Warwick-Edinburgh Mental Well-Being Scale).

Results Of the 7250 participants included, the mean (SD) age was 13.7 (0.6) years, 3947 (55.4%) identified as female, and 5378 (73.1%) self-reported their race as White. Twelve schools and 769 of the 864 students (89.0%) in cohort 1 and 54 schools and 2958 of the 6386 students (46.3%) in cohort 2 provided data and were analyzed. Mental health difficulties increased in both cohorts but to a greater extent among students exposed to the pandemic, including for risk of depression (adjusted mean difference [AMD], 1.91; 95% CI, 1.07-2.76); social, emotional, and behavioral difficulties (AMD, 0.76; 95% CI, 0.33-1.18); and mental well-being (AMD, −2.08; 95% CI, −2.80 to −1.36). Positive school climate, high home connectedness, and having a friend during lockdown were protective factors during the pandemic. Female gender and initial low risk for mental health difficulties were associated with greater mental health deteriorations. Partial school attendance during lockdown was associated with better adjustment than no attendance when returning to school.

Conclusions and Relevance This cohort study of secondary school students demonstrated that to promote mental health and adjustment, policy interventions should foster home connectedness, peer friendship, and school climate; avoid full school closures; and consider individual differences.

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.
