Understanding deviations from typical brain development is a promising approach to comprehend pathophysiology in childhood and adolescence. We investigated if cerebellar volumes different than expected for age and sex could predict psychopathology, executive functions and academic achievement.

Children and adolescents aged 6–17 years from the Brazilian High-Risk Cohort Study for Mental Conditions had their cerebellar volume estimated using Multiple Automatically Generated Templates from T1-weighted images at baseline (n = 677) and at 3-year follow-up (n = 447). Outcomes were assessed using the Child Behavior Checklist and standardized measures of executive functions and school achievement. Models of typically developing cerebellum were based on a subsample not exposed to risk factors and without mental-health conditions (n = 216). Deviations from this model were constructed for the remaining individuals (n = 461) and standardized variation from age and sex trajectory model was used to predict outcomes in cross-sectional, longitudinal and mediation analyses.

Cerebellar volumes higher than expected for age and sex were associated with lower externalizing specific factor and higher executive functions. In a longitudinal analysis, deviations from typical development at baseline predicted inhibitory control at follow-up, and cerebellar deviation changes from baseline to follow-up predicted changes in reading and writing abilities. The association between deviations in cerebellar volume and academic achievement was mediated by inhibitory control.

Deviations in the cerebellar typical development are associated with outcomes in youth that have long-lasting consequences. This study highlights both the potential of typical developing models and the important role of the cerebellum in mental health, cognition and education.

This study aimed to examine cross-sectional and longitudinal associations between dietary intake and educational outcomes (EO) in Australian first-year university students.

This cross-sectional and longitudinal study measured outcomes of interest at three points over 1 year. Measures included self-reported dietary patterns and dietary intake via a three-day estimated food record. Objective EO (corresponding semester grade point average (GPA), overall GPA and graduation status) variables were extracted from academic records. Cross-sectional and longitudinal associations were examined using regression models and generalised estimating equations, respectively.

A large university in Queensland, Australia.

Participants (n 80) were first-year students who had completed high school in the previous year.

Some significant associations were found with semester GPA, including: (a) moderate positive associations between serves of vegetables and semester GPA at time point 2 and over time; and (b) a weak negative association between Na intake and semester GPA at time point 2. Although insignificant, meaningful negative associations were found between alcohol consumption and semester GPA at time point 1 and over time. Some significant associations were also found with graduation status, including: (a) a positive association between meeting Australian carbohydrate recommendations and graduation status; and (b) a negative association between Fe intake and graduation status, both at time point 1.

Both cross-sectional and longitudinal findings highlight positive associations between vegetable intake and EO and negative associations between alcohol consumption and EO. Further relevant work is needed with larger, more variable samples in demographic, dietary and EO characteristics.

This article explores the relationship between childhood obesity and educational outcomes in Mexico, a country where excess weight is predominant.

Using complementary multivariate estimators, we empirically investigate the association between childhood excess weight, measured in 2002, and schooling attainment measured 10 years later. Non-linear specifications are tested, and heterogeneous effects according to gender, living area and economic backgrounds are investigated.

To fill the literature gap, this study focuses on the understudied context of emerging countries such as Mexico.

Panel data from the Mexican Family Life Survey (2002–2012) are used. We restricted the sample to adolescent individuals who had between 9 and 15 years old in 2002 (attended primary or secondary school in 2002). The survey provides an accurate follow-up information on weight, height and waist circumference for each individual.

Controlling for a comprehensive set of covariates, we find that the relationship is non-linear in Mexico. While weight-based childhood obesity and abdominal adiposity are significantly associated with lower school attainment, at least in urban settings, no schooling gap is found between overweight students and their normal-weight counterparts. Along with rural–urban heterogeneity, obesity-based educational penalties appear to be stronger for girls and students from privileged economic backgrounds.

These results emphasise the co-occurrence of anti-fat and pro-fat social norms in Mexican schools: while anti-fat norms may particularly concern female, richer and urban students, pro-fat norms might persist among male, poorer and rural students. These findings have important implications for public policy, namely about awareness anti-obesity programmes.

We examined the association of household food insecurity with educational outcomes and explored the moderating effect of gender and school lunch programme.

The study used a cross-sectional design. Data were collected in 2014 using interviewer-administered questionnaires and school administrative records. We measured household food insecurity using the Household Food Insecurity Access Scale. Educational outcomes referred to knowledge, attitudes and skills that students are expected to obtain while attending school. We obtained sixteen different measures of educational outcomes, ranging from academic grades to beliefs and attitudes towards school and education. Data were analysed using multilevel modelling with covariates at the student and school levels. We conducted moderation tests by adding a two-way interaction between food insecurity and gender, and between food insecurity and school lunch programme.

The study was conducted in 100 schools located in fifty-four districts within Ghana’s eight administrative regions in 2014.

Participants included 2201 school-going adolescents aged 15–19 years.

More than 60 % of adolescents were from food-insecure households. Household food insecurity was negatively associated with Math grade and school attendance. Food insecurity was also inversely associated with socio-emotional outcomes, including academic self-efficacy, commitment to school and academic aspirations and expectations. We did not find a moderating effect of gender and school lunch programme.

Food insecurity is negatively associated with wide-ranging educational outcomes related to both learning and socio-emotional abilities. Our study supports prior evidence suggesting the importance of food access on both cognitive and non-cognitive educational outcomes.

To review existing literature about university students with Attention Deficit Hyperactivity Disorder (ADHD).

A framework for scoping studies and content analysis were used to source and review selected publications from PubMed, ScienceDirect, Google Scholar and relevant bibliographies.

Seventy-four publications were reviewed and key findings were categorised under six core themes that represent the issues germane to university students with ADHD. These themes are: academic, social and psychological functioning, giftedness, new media technologies, treatment, substance misuse and the non-medical use of prescription stimulants, and malingering.

In Ireland and the United Kingdom (UK) young people with ADHD are unlikely to enrol into further education, and of those who do go to university, few will graduate at the same time as their non-ADHD peers. ADHD is associated with poor educational outcomes and it may be a hidden disability within institutions of higher education (e.g. universities). Surprisingly, in this topic area, there is a paucity of research in Ireland and the UK. Most studies originate from North America were research activity in the field has been ongoing since the 1990s. These studies however, tend to use relatively small samples of college (university) students recruited at a single institution. It is difficult to generalise the findings of these studies to student populations in North America, let alone in Ireland and the UK. At the very least, these North American studies provide insights into key areas of concern. This topic area straddles education and psychiatry. This means an inter-disciplinary approach is required to examine, better understand and address the impact of ADHD on the educational outcomes of university students. The philosophies of difference, equity and self-realisation can offer a conceptual framework for conducting further research and/or developing services to deliver more personalised learning support for university students with ADHD.

Breakfast consumption has been consistently associated with health outcomes and cognitive functioning in schoolchildren. Evidence of direct links with educational outcomes remains equivocal. We aimed to examine the link between breakfast consumption in 9–11-year-old children and educational outcomes obtained 6–18 months later.

Data on individual-level free school meal entitlement and educational outcomes (Statutory Assessment Tests (SATs) at Key Stage 2) were obtained via the SAIL databank and linked to earlier data collected on breakfast consumption. Multilevel modelling assessed associations between breakfast consumption and SATs.

Trial of the Primary School Free Breakfast Initiative in Wales.

Year 5 and 6 students, n 3093 (baseline) and n 3055 (follow-up).

Significant associations were found between all dietary behaviours and better performance in SATs, adjusted for gender and individual- and school-level free school meal entitlement (OR=1·95; CI 1·58, 2·40 for breakfast, OR=1·08; CI 1·04, 1·13 for healthy breakfast items). No association was observed between number of unhealthy breakfast items consumed and educational performance. Association of breakfast consumption with educational performance was stronger where the measure of breakfast consumption was more proximal to SATs tests (OR=2·02 measured 6 months prior to SATs, OR=1·61 measured 18 months prior).

Significant positive associations between self-reported breakfast consumption and educational outcomes were observed. Future research should aim to explore the mechanisms by which breakfast consumption and educational outcomes are linked, and understand how to promote breakfast consumption among schoolchildren. Communicating findings of educational benefits to schools may help to enhance buy-in to efforts to improve health behaviours of pupils.
