Household food insecurity (HFI) is a social determinant of health globally. Rates of HFI have risen in many high-income countries in recent years, particularly in households with children. The health outcomes associated with HFI for children and adolescents have not been systematically synthesised. This review was conducted to support advocacy efforts for meaningful policy action to reduce HFI in households with children.

A systematic search was conducted in Medline, Embase and PsycInfo databases. Primary studies measuring the association between physical or mental health outcomes and HFI were included. Studies were appraised and population, setting, measures and outcomes were extracted. Findings were grouped by related outcomes. Due to heterogeneity, findings were synthesised narratively. Rapid review methodology was used to accommodate resource constraints.

High-income countries.

Youth aged less than 18 years.

Thirty-six studies were included. Most were cross-sectional studies conducted in the USA. Outcomes included general health, early childhood, cardiometabolic, asthma, dental caries, mental health, sleep, diet and anaemia. Despite substantial heterogeneity in HFI measures and analysis, findings support associations between HFI and negative outcomes for general health status, asthma, dental caries and mental health. Findings for other outcomes were mixed.

This review clarifies the effects of HFI on children and adolescents. Findings highlight trends for negative physical and mental health outcomes associated with HFI during youth, particularly related to mental health, oral health, asthma and general health status. Policy-level action should address rising rates of HFI and long-term effects on these vulnerable populations.

Childhood irritability increases the risk of later suicidal behaviors, but the moderators of this association have not been identified. We investigated harsh parenting as a moderator in the association of childhood irritability with adolescent suicide attempt and self-harm, and possible sex differences in these associations.

Data were from 9,480 children from the Millennium Cohort Study. We averaged parent ratings of child irritability and harsh parenting at ages 3, 5, and 7 years (range 1–3). Suicide attempt and self-harm were self-reported at age 17. Logistic regression models were used to estimate associations of irritability with suicide attempt and self-harm, adjusting for confounding factors. Interaction analyses were used to test the moderating role of harsh parenting and sex in these associations.

Children with greater irritability scores were at increased risk to attempt suicide (OR=1.72, 95% CI=1.42–2.08). Interaction analyses suggested that this risk in males was elevated regardless of harsh parenting. However, high levels of harsh parenting interacted with irritability in increasing the risk of suicide attempt in females. Children with high irritability were also more at risk of self-harm (OR = 1.16, 95% CI = 1.03–1.31) but this association was not moderated by harsh parenting in either sex.

Parental behaviors may play an important role in the pathway to suicide attempt of children with irritability, especially for females, who may have a heightened sensitivity to interpersonal stressors. Parenting interventions may be helpful in suicide prevention among females with irritability.

Mental ill-health has a major impact on young people, with pain often co-occurring. We estimated the prevalence and impact of pain in young people with mental ill-health.

Longitudinal data (baseline and three-month follow-up) of 1,107 Australian young people (aged 12–25 years) attending one of five youth mental health services. Multi-level linear mixed models estimated associations between pain characteristics (frequency, intensity, and limitations) and outcomes with false discovery rate (FDR) adjustment. Pain characteristics were baseline-centered to estimate if the baseline score (between-participant effect) and/or change from baseline (within-participant effect) was associated with outcomes.

At baseline, 16% reported serious pain more than 3 days, 51% reported at least moderate pain, and 25% reported pain-related activity limitations in the last week. Between participants, higher serious pain frequency was associated with greater anxiety symptoms (β[95%CI]: 0.90 [0.45, 1.35], FDR-p=0.001), higher pain intensity was associated with greater symptoms of depression (1.50 [0.71, 2.28], FDR-p=0.001), anxiety (1.22 [0.56, 1.89], FDR-p=0.002), and suicidal ideation (3.47 [0.98, 5.96], FDR-p=0.020), and higher pain limitations were associated with greater depressive symptoms (1.13 [0.63, 1.63], FDR-p<0.001). Within participants, increases in pain intensity were associated with increases in tobacco use risk (1.09 [0.48, 1.70], FDR-p=0.002), and increases in pain limitations were associated with increases in depressive symptoms (0.99 [0.54, 1.43], FDR-p<0.001) and decreases in social and occupational functioning (−1.08 [−1.78, −0.38], FDR-p=0.009).

One-in-two young people seeking support for mental ill-health report pain. Youth mental health services should consider integrating pain management.

Youth suicidal ideation and behaviour are major significant concerns, with suicide being the third leading cause of death among youth. In recent years, the trend toward deinstitutionalisation has caused parents of high-risk youth to face increasing emotional and practical challenges, including managing lethal means restriction (LMR) to reduce suicide risk.

This qualitative study explores the experiences of parents instructed by mental health professionals to restrict their child’s access to lethal means in managing suicidal behaviours.

Twelve Israeli parents of youth aged 12–21 years participated in in-depth interviews. Using interpretative phenomenological analysis, the study investigated the emotional, psychological and relational challenges parents face when implementing LMR.

Findings indicate that parents struggle to understand and implement LMR guidance, experience emotional strain from their role as protectors, and face pervasive anxiety about their child’s safety. The study also highlights feelings of helplessness and the erosion of trust between parents and children. Many parents criticise LMR, viewing it as potentially harmful to their relationship with their child or ineffective at keeping their child safe.

This study underscores the emotional and practical challenges parents face when implementing LMR. To improve its effectiveness, guidance should be re-evaluated and communicated more flexibly, emphasising shared responsibility between the parent and child, and address the emotional toll on parents during this critical period.

A key step toward understanding psychiatric disorders that disproportionately impact female mental health is delineating the emergence of sex-specific patterns of brain organisation at the critical transition from childhood to adolescence. Prior work suggests that individual differences in the spatial organisation of functional brain networks across the cortex are associated with psychopathology and differ systematically by sex.

We aimed to evaluate the impact of sex on the spatial organisation of person-specific functional brain networks.

We leveraged person-specific atlases of functional brain networks, defined using non-negative matrix factorisation, in a sample of n = 6437 youths from the Adolescent Brain Cognitive Development Study. Across independent discovery and replication samples, we used generalised additive models to uncover associations between sex and the spatial layout (topography) of personalised functional networks (PFNs). We also trained support vector machines to classify participants’ sex from multivariate patterns of PFN topography.

Sex differences in PFN topography were greatest in association networks including the frontoparietal, ventral attention and default mode networks. Machine learning models trained on participants’ PFNs were able to classify participant sex with high accuracy.

Sex differences in PFN topography are robust, and replicate across large-scale samples of youth. These results suggest a potential contributor to the female-biased risk in depressive and anxiety disorders that emerge at the transition from childhood to adolescence.

Despite strong evidence linking exposure to food and beverage marketing with poor diet quality and negative health impacts in children, the effect of brand marketing (i.e. marketing featuring branded content, but no food products) is uncertain. This study evaluated the impact of brand marketing v. product-based advertising on children’s food preferences and behavioural intentions.

An online survey was administered to participants randomised to one of four ad conditions; familiar product (i.e. from popular Canadian brands); familiar brand (i.e. no food product, Canadian brand); unfamiliar product (i.e. foreign products); and unfamiliar brand ad (i.e. foreign brand). Participants viewed three ads displaying features of that condition and answered three 5-point Likert-scale questions related to the study outcomes: food preference, purchase intent and pester power. The average of all outcomes determined the total impact. An ANOVA with Bonferroni post hoc tests evaluated differences in impact between conditions.

Canada participants: n 1341 Canadian children (9–12 years)

Familiar product ads had a higher total impact on children (mean score 3·57) compared with familiar brand ads (2·88), unfamiliar brand ads (3·24) or unfamiliar product ads (3·09; P < 0·001 for all pairwise comparisons). Total impact was lower for familiar brand ads than for unfamiliar brand ads or unfamiliar product ads (P < 0·001 for all pairwise comparisons). The impact of an unfamiliar brand and product did not differ (P = 0·53).

Results suggest that familiar product ads seem to have a stronger impact on children’s food preferences and behavioural intentions than familiar brand ads, unfamiliar brand ads and unfamiliar product ads.
