Socioeconomic status, stressful life situations and mental health problems in children and adolescents: Results of the German BELLA cohort-study

Enduring Neurobiological Consequences of Early-Life Stress: Insights from Rodent Behavioral Paradigms

Stress profoundly affects physical and mental health, particularly when experienced early in life. Early-life stress (ELS) encompasses adverse childhood experiences such as abuse, neglect, violence, or chronic poverty. These stressors can induce long-lasting changes in brain structure and function, impacting areas involved in emotion regulation, cognition, and stress response. Consequently, individuals exposed to high levels of ELS are at an increased risk for mental health disorders like depression, anxiety, and post-traumatic stress disorders, as well as physical health issues, including metabolic disorders, cardiovascular disease, and cancer. This review explores the biological and psychological consequences of early-life adversity paradigms in rodents, such as maternal separation or deprivation and limited bedding or nesting. The study of these experimental models have revealed that the organism's response to ELS is complex, involving genetic and epigenetic mechanisms, and is associated with the dysregulation of physiological systems like the nervous, neuroendocrine, and immune systems, in a sex-dependent fashion. Understanding the impact of ELS is crucial for developing effective interventions and preventive strategies in humans exposed to stressful or traumatic experiences in childhood.

A systematic review and meta-analysis on the prevalence of mental disorders among children and adolescents in Europe

Most mental disorders appear by age 14, but in most cases, they remain undiagnosed and untreated well into adulthood. A scoping review showed an absence of systematic reviews that address prevalence rates of mental disorders among children and adolescents in Europe that are based on community studies conducted between 2015 and 2020. To estimate the updated pooled prevalence of Anxiety Disorder, Depressive Disorder, Attention Deficit Hyperactivity Disorder (ADHD), Conduct Disorder (CD), Oppositional Defiant Disorder (ODD), Autism Spectrum Disorder, Eating Disorders, Substance Use Disorders (SUD), among children and adolescents living in Europe, a search strategy was conducted using MEDLINE, Embase and Psych Info and studies were also identified from reference lists and gray literature. Eligible studies were evaluated for reliability, validity, and bias. Trends of prevalence rates for each mental disorder were calculated. Almost one in five young people in Europe were found to suffer from a mental disorder, with a pooled prevalence rate of 15.5%. Anxiety disorders had the highest pooled prevalence rate (7.9% (95% CI 5.1-11.8%, I2: 98.0%)), followed by ADHD (2.9% (95% CI 1.2-6.9%, I2 = 94.3%)), ODD (1.9% (95% CI 1.0-3.7%, I2 = 98.4%)), depressive disorder (1.7% (95% CI 1.0-2.9%, I2 = 97.7%)), CD (1.5% (95% CI 0.6-3.8%, I2 = 98.8%)) and ASD (1.4% (95% CI 0.4-5.4%, I2 = 99.7%). No studies on SUD were identified. The mental health of children and adolescents may be improved by introducing routine screening, refining diagnostic sensitivity, raising awareness of mental disorders, minimizing stigma and socioeconomic inequality, as well as developing early intervention services. These facilitators of good mental health need to be prioritized, especially at a time of unprecedented risk factors for poor mental health.

Socioeconomic status moderates associations between hippocampal development and cognition in preterms

OBJECTIVE

The hippocampus plays a critical role in cognitive networks. The anterior hippocampus is vulnerable to early-life stress and socioeconomic status (SES) with alterations persisting beyond childhood. How SES modifies the relationship between early hippocampal development and cognition remains poorly understood. This study examined associations between SES, structural and functional development of neonatal hippocampus, and 18-month cognition in very preterm neonates.

METHODS

In total, 179 preterm neonates were followed prospectively. Structural and resting-state functional MRI were obtained early-in-life and at term-equivalent age (median 32.9 and 41.1 weeks post-menstrual age) to calculate anterior and posterior hippocampal volumes and hippocampal functional connectivity strength. Eighteen-month cognition was assessed via Bayley-III. Longitudinal statistical analysis using generalized estimating equations, accounting for birth gestational age, post-menstrual age at scan, sex, and motion, was performed.

RESULTS

SES, measured as maternal education level, modified associations between anterior but not posterior hippocampal volumes and 18-month cognition (interaction term p = 0.005), and between hippocampal connectivity and cognition (interaction term p = 0.05). Greater anterior hippocampal volumes and hippocampal connectivity were associated with higher cognitive scores only in the lowest SES group. Maternal education alone did not predict neonatal hippocampal volume from early-in-life and term.

INTERPRETATION

SES modified the relationship between neonatal hippocampal development and 18-month cognition in very preterm neonates. The lack of direct association between maternal education and neonatal hippocampal volumes indicates that socio-environmental factors beyond the neonatal period contribute to modifying the relationship between hippocampal development and cognition. These findings point toward opportunities to more equitably promote optimal neurodevelopmental outcomes in very preterm infants.

Oral issues and childhood stress in eight-to-ten-year-old schoolchildren: a case-control study

OBJECTIVE

The aim of the present study was to investigate whether oral problems, harmful oral habits, and sociodemographic factors are associated with the occurrence of stress in schoolchildren.

MATERIALS AND METHODS

A case-control study nested within a cross-sectional study was conducted with a sample of 375 schoolchildren eight to ten years of age in the city of Diamantina, Brazil. The case group (with childhood stress) and control group (without childhood stress) were matched for age and sex at a 1:4 ratio (75 cases to 300 controls). Data collection involved the self-administration of a questionnaire by parents/caregivers addressing sociodemographic characteristics and the child's history of harmful oral habits. The children answered the Child Stress Scale (CSS) and underwent a clinical oral examination to determine the presence/absence of dental caries, malocclusion, and traumatic dental injuries. Data analysis involved the calculation of frequencies, the chi-square test, and conditional logistic regression (95% CI; p ≤ 0.05).

RESULTS

The final adjusted conditional logistic regression model showed that dental caries (OR = 1.78, 95% CI: 1.01 - 3.14, p = 0.044) and biting objects (OR = 1.81, 95% CI: 1.02 - 3.22, p = 0.041) remained associated with stress in the schoolchildren analysed.

CONCLUSION

The present results showed that children with dental caries and the habit of biting objects were more likely to have childhood stress.

CLINICAL RELEVANCE

The study allows paediatric dentists to expand their knowledge with regards to the influence of oral problems and harmful habits on the occurrence of childhood stress and serves as a guide for decision-making related to oral problems in schoolchildren.

Children and adolescents weathering the storm: Resilience in the presence of bullying victimization, harassment, and pandemic lockdown in northern Norway

Resilience is a concept of growing interest because it can systematically inform prevention measures and psychosocial interventions for children and adolescents. The aim of this study was to explore resilience factors among young people who are victims of bullying and harassment (age 9 to 16 years old). In 2021 the burden of the pandemic lockdown became an additional adversity. The study used a repeated cross-sectional design. Two datasets with a total of 2,211 participants from 2017 (N = 972) and 2021 (N = 1,239) were included. The strengths and difficulties questionnaire (SDQ) was applied to define the resilient and non-resilient groups, and the quality-of-life questionnaire (KINDL) was used to map resilience factors. A total of 227 participants reported that they were being bullied, and 604 participants reported harassments from their peers. We used correlation and regression analyses to identify which factors predicted the highest resistance to the negative effects of bullying and harassment. The results were that 77.2% of the participants stayed resilient when facing these maladjustments, but this dropped to 61.7% during the pandemic. The most important resilience factors before the pandemic were the school environment, emotional well-being, and good relations with their friends. The impact of these predictors changed during the pandemic. Emotional well-being increased in strength, school environment was reduced, and friends did not predict resilience anymore. The effect sizes were generally large to medium. As it is common to experience adversity at some stage in life, it is vital for families, schools, social and healthcare workers to be aware of the factors associated with resilience. The results of this study may contribute towards an evidence base for developing plans to increase the capacity of resilience among young people.

Identifying multilevel predictors of trajectories of psychopathology and resilience among juvenile offenders: A machine learning approach

Mental ill health is more common among juvenile offenders relative to adolescents in general. Little is known about individual differences in their long-term psychological adaptation and its predictors from multiple aspects of their life. This study aims to identify heterogeneous trajectories of probable psychiatric conditions and their predictors. Participants included 574 juvenile offenders who were first convicted for serious crimes and without detention history. The participants were assessed at 11 timepoints over seven years (2000-2010). Growth mixture modeling revealed the same three trajectories for both probable anxiety and probable depression: stable low trajectory (75.96%; 75.78%), stable high trajectory (15.16%; 10.98%), and recovery (8.89%, 13.24%). Least absolute shrinkage and selection operator (LASSO) logistic regression identified three multilevel predictors for memberships of different trajectories. Risk factors against stable low trajectory lay within personal (e.g., neuroticism), relationship (e.g., parental hostility), and contextual levels (e.g., chaotic neighborhood). Resilience factors for stable low trajectory included strong work orientation and low education level of father. Recovery was predicted by Black race, self-identity, high education level of father, and nonincarcerated sentencing. Our findings suggest that both psychopathology and psychological resilience could be predicted by multiple personal, relationship, and contextual factors in the social ecology of juvenile offenders.

Comparative Analysis of Stress Levels Among Undergraduate Students at St. John's College, Agra

Background Stress is prevalent among college students, impacting their mental health and academic performance. Understanding the distribution and determinants of stress levels in students is crucial for developing effective interventions. This study aims to assess the prevalence of stress and its association with sociodemographic factors among undergraduate students at St. John's College, Agra, India. Materials and methods A descriptive cross-sectional study was conducted between August 1, 2023, and December 31, 2023, involving 160 undergraduate students from B.A., B. Com., and B.Sc. programs. Students were selected using a stratified random sampling technique. Stress levels were measured using the Perceived Stress Scale (PSS), which classifies low, moderate, and high levels. Data were collected through a validated, semi-structured questionnaire administered via Google Forms. Statistical analysis was performed using IBM SPSS Statistics for Windows, Version 29 (Released 2023; IBM Corp., Armonk, New York), with descriptive statistics and chi-square tests used to examine associations between stress levels and sociodemographic variables. Results The study found that 103 (64.4%) of students experienced moderate stress, 34 (21.3%) reported high perceived stress, and 23 (14.4%) had low stress. A significant association was observed between stress levels and gender (p = 0.022), with female students more likely to experience high stress. Additionally, urban students reported higher stress levels than their rural counterparts (p = 0.012). However, no significant differences in stress levels were found across different courses. Conclusion The study reveals a substantial prevalence of moderate to high stress among college students, particularly among females and those from urban areas. These findings suggest the need for targeted stress management interventions to support student well-being. Further research is recommended to explore the underlying causes of stress and develop comprehensive stress reduction strategies in the student population.

Electronic device usage among preschool children and its association with mental health status in Saudi Arabian kindergartens

OBJECTIVES

To estimate the prevalence of electronic device usage and its association with mental health status among preschool children aged 3-6 years.

METHODS

A cross-sectional study was conducted among preschool children aged 3-6 years in kindergartens in Makkah city in 2023-2024, using an electronic questionnaire. An Arabic version of the Strengths and Difficulties Questionnaire was used to assess mental health.

RESULTS

We recruited a total of 399 children. The prevalence of electronic device usage was 91.5%. The number of hours spent using electronic devices ranged from 0 to 12 hour (h)/day, with a mean of 3.1 h/day. We found a significant positive correlation between the number of hours spent using electronic devices and emotional problems (r=0.200, p<0.001), conduct problems (r=0.149, p=0.003), hyperactivity (r=0.279, p<0.001), peer problems (r=0.104, p=0.038), and total difficulty scores (r=0.263, p<0.001). We also found a significant negative correlation between the number of hours spent using electronic devices and the prosocial score (r= -0.128, p=0.011), and most of the included children had scores within the "close to average" category across all scales of mental health status.

CONCLUSION

There was a high prevalence of electronic device usage among preschool children, which exceeded the recommended time limit. A significant correlation was observed between electronic device use and mental health scores. Further longitudinal studies are required to understand the nature of this association and its implications for child development.

A PERMA model approach to well-being: a psychometric properties study

Psychological well-being influences all the facets of adolescent success. This study examined the psychometric properties of PERMA, a subjective well-being measure consisting of five domains: positive emotions, engagement, relationships, meaning, and accomplishment. The sample size consisted of 502 high school students from public schools in Qatar. Contrary to expectations, the five-factor structure for PERMA did not fit our data well; however, after refining the model by the errors of the covariances between items, the one-factor model was found to be applicable. Multivariate analysis revealed that socioeconomic status (SES) and level of academic performance were independently and positively associated with overall well-being scores, whereas internalizing and externalizing behaviors were negatively associated. Notably, no significant effects of gender or age on well-being were observed. These findings suggest that interventions specific to socioeconomic status, academic excellence, and internalizing and externalizing behaviors in the school setting can produce more effective outcomes concerning student well-being.

Emphasizing symbolic capital: its superior influence on the association between family socioeconomic status and adolescent subjective well-being uncovered by a large-scale multivariate network analysis

Background

Family socioeconomic status (FSES) serves as a significant determinant for subjective well-being. However, extant research has provided conflicting evidence on the correlation between FSES and adolescent students' subjective well-being (SSWB).

Methods

Data were collected from 12,058 adolescent students (16 years of age) by the Programme for International Student Assessment (PISA) 2018. Multivariate canonical correlation and Mantel test were utilized to investigate the specific connection between FSES and SSWB. Furthermore, a Gaussian EBICglasso graph-theoretical model was used to capture the topological properties of the FSES-SSWB network and reveal the interplay among multifarious components of FSES and SSWB.

Results

FSES was positively correlated with SSWB. In the FSES-SSWB network, parental educational attainment and occupation status demonstrated the highest centrality values, thereby contributing significantly to the relationship between FSES and SSWB. However, family wealth, along with educational and cultural resources, displayed lower centrality values, signifying their weaker roles in this relationship.

Conclusion

Our findings suggest that symbolic capital, rather than family affluence, exerts a dominant influence on adolescent SSWB. In other words, SSWB may not be detrimentally influenced by a deficiency in monetary resources. However, it is more susceptible to being unfavorably impacted by inferior parental educational attainment and occupational standing.

Unveiling the Moderating Factors in the Relationship between Physical Activity and Health-Related Quality of Life among University Students during COVID-19: A Mixed Study Design

This study examines the moderating effects of various factors on the relationship between physical activity (PA) and health-related quality of life (HRQoL) among 287 female college students during the COVID-19 pandemic. Data were collected through an online questionnaire covering health issues, PA, self-esteem, HRQoL, and sociodemographic information, supplemented by semi-structured interviews and focus groups with six participants. Results showed that 46% of respondents had good HRQoL, and 38% were physically active. The interactions of age, socioeconomic status (SES), and academic performance with PA on HRQoL were insignificant. However, physical and mental health problems significantly moderated the PA-HRQoL relationship, accounting for 1% and 4% of the variance, respectively. The qualitative analysis highlighted the need for student activity clubs and mental health support to enhance coping strategies and overall HRQoL. In conclusion, age and SES did not moderate the PA-HRQoL relationship, while physical and mental health issues did. Programs targeting students with health problems are crucial to improving their physical and mental health, thereby enhancing their well-being.

Global burden of skin and subcutaneous diseases and its association with socioeconomic status in children and adolescents: an analysis of the Global Burden of Diseases Study 2019

Skin and subcutaneous diseases are one of the most common problems affecting the health of children and adolescents. The purpose of this study was to investigate the burden of skin and subcutaneous diseases among children and adolescents and its association with socioeconomic status. Data was obtained from the Global Burden of Disease Study 2019. The number of cases, incidence rate, number of deaths, and death rate in 204 countries and territories from 1990 to 2019 were extracted and stratified by age, sex, and socioeconomic status. In 2019, the global incidence and death rates of skin and subcutaneous diseases in children and adolescents were 57966.98 (95% Uncertainty Interval [UI] 53776.15 to 62521.24) per 100,000 and 0.21 (95% UI 0.13 to 0.26) per 100,000, respectively. From 1990 to 2019, the global incidence rate increased by 5.80% (95% UI 4.82-6.72%) and the death rate decreased by 43.68% (95% UI 23.04-65.27%). The incidence and death rates were negatively correlated with socioeconomic status. Incidence rates were not different between females and males, but death rates were higher among females than males. The highest incidence and death rates were found in the 1-4-year age group and < 1-year age group, respectively. The global burden of skin and subcutaneous diseases in children and adolescents was characterized by regional imbalances. The global burden of skin and subcutaneous diseases in children and adolescents from poorer regions requires more attention. This study provides strong evidence for global policymaking for childhood and adolescent diseases.

Mental health difficulties and related factors in Chinese children and adolescents during the COVID-19 pandemic: a cross-sectional study

OBJECTIVE

To examine the mental health status and related factors in children and adolescents, and to assess age groups and sexes differences in factors influencing mental health.

METHODS

This cross-sectional study was performed on Chinese children aged 6-18 years from November 2021 to January 2022. Mental health difficulties were accessed by the Strengths and Difficulties Questionnaire. Multivariate logistic regression was used to analyze factors associated with mental health status. Multiple linear regression was used to evaluate factors associated with the scores of the Strengths and Difficulties Questionnaire.

RESULTS

The prevalence of mental health difficulties was 12.98% (n =1348). Age (OR, 0.909, [95%CI, 0.830-0.996]), sex (OR, 1.424, [95%CI, 1.033-1.963]) and screen time on weekdays ("≥2" h/d vs "< 1" h/d: OR, 2.001, [95%CI, 1.300-3.080]) were related factors for mental health difficulties. For children (year ≤ 12), the strongest related factor for mental health difficulties was screen time on weekdays ("≥ 2" h/d vs "< 1" h/d: OR, 1.821 [95%CI, 1.203-2.755]). The risk of mental health difficulties in females with ≥ 2 h/d screen time on weekends was 3.420 times higher than those with < 1 h/d (OR, 3.420, [95%CI, 1.923-6.081]).

CONCLUSION

The prevalence of mental health difficulties among children and adolescents was relatively high. The lower age, female sex and excessive screen time were associated with a higher risk of mental health difficulties. The factors influencing mental health varied by different age groups and sexes. Thus, specific measures for different age groups and sexes should be adopted to mitigate the impact.

Structural and functional brain correlates of socioeconomic status across the life span: A systematic review

It is well-established that higher socioeconomic status (SES) is associated with improved brain health. However, the effects of SES across different life stages on brain structure and function is still equivocal. In this systematic review, we aimed to synthesise findings from life course neuroimaging studies that investigated the structural and functional brain correlates of SES across the life span. The results indicated that higher SES across different life stages were independently and cumulatively related to neural outcomes typically reflective of greater brain health (e.g., increased cortical thickness, grey matter volume, fractional anisotropy, and network segregation) in adult individuals. The results also demonstrated that the corticolimbic system was most commonly impacted by socioeconomic disadvantages across the life span. This review highlights the importance of taking into account SES across the life span when studying its effects on brain health. It also provides directions for future research including the need for longitudinal and multimodal research that can inform effective policy interventions tailored to specific life stages.

Family structure, socioeconomic status, and mental health in childhood

The changing landscape of family structures over the last decades has led to a growing need to investigate its impact on children's well-being. This study examined differences in mental health among children from different family compositions and how these differences may be affected by familial socioeconomic status (SES). Data were collected within the LIFE Child study. Participants included 2828 children aged 3-17 years raised in traditional families, stepfamilies, or single-parent families. Mental health was measured using the Strengths and Difficulties Questionnaire (SDQ (behavioral strengths and difficulties)) and the KIDSCREEN-27 questionnaire (quality of life). Linear regression analyses were applied to examine associations between family structure, SES, and mental health outcomes. Children from single-parent families exhibited worse mental health outcomes than those from traditional families across all domains of the SDQ and the KIDSCREEN-27. Children from stepfamilies showed significantly higher Total Difficulties scores (B = 1.29 and 1.42), with 3- to 10-year-olds displaying higher scores in the Hyperactivity & Inattention (B = 0.61) and Peer Relationship Problems (B = 0.36) subscales, and 11- to 17-year-olds showing higher Conduct Problems (B = 0.31), Emotional Symptoms (B = 0.58), and a worse Parent Relationship scores (B = - 1.82) than children from traditional families (all p < 0.05). After controlling for SES, several associations between family structure and mental health lost significance, while others persisted, particularly among older children. To promote mental health in non-traditional families, interventions should address socioeconomic disparities while also investigating factors contributing to the direct impact of family structure on mental well-being.Trial registration The LIFE Child study is registered on clinicaltrials.gov (No. NCT02550236).

Trends in adolescent mental health problems 2004-2020: Do sex and socioeconomic status play any role?

AIMS

This study aims to investigate trends in four types of adolescent mental health problems; that is, psychosomatic symptoms, depressive symptoms, suicidal ideations, and suicide attempts 2004-2020. A second aim is to investigate the moderating roles of socioeconomic status and sex in these trends.

METHODS

The analysis is based on repeated cross-sectional data 2004-2020 among grade 9 students in secondary schools in a Swedish county. In total, data from 19,873 students were included in the analysis. We fitted linear and logistic regression equations and used survey-years' coefficients to estimate the trends. We also estimated the moderating effects of socioeconomic status and sex using interactions between survey year and socioeconomic status and sex, respectively.

RESULTS

The trends in all mental health problems declined over time. Through its interaction with survey year, socioeconomic status moderated the trends; psychosomatic symptoms (B = -0.115, P<0.001), depressive symptoms (B = -0.084, P<0.001) and suicidal ideations (odds ratio 0.953, confidence interval 0.924-0.983) significantly declined over time among those with high socioeconomic status. However, socioeconomic status did not have an association with the trend in suicide attempts. Interaction between sex and year of survey was associated with significant decreasing trends in depressive symptoms and suicidal ideations only among girls.

CONCLUSIONS

Adolescent mental health problems have decreased over time, but only for adolescents with high socioeconomic status, or only in depressive symptoms and suicidal ideations for girls. The results shed light on the growing inequalities in health outcomes across levels of socioeconomic status.

Early environmental predictors for attention-deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD) and their co-occurrence: The prospective ABIS-Study

ADHD and ASD are highly heritable and show a high co-occurrence and persistence into adulthood. This study aimed to identify pre and perinatal risk factors, and early psychosocial exposures related to later diagnosis of ADHD, ASD, and their co-occurrence. 16,365 children born 1997-1999 and their families, involved in the prospective population-based ABIS study (All Babies in Southeast Sweden), were included in this sub-study. Pre and perinatal factors and early environmental psychosocial exposures were collected from parental-questionnaires at birth and 1-year follow-up. Diagnoses from birth up to 23 years of age were obtained from the Swedish National Diagnosis Register in 2020. The cumulative incidence of ADHD, ASD, and their co-occurrence in the ABIS-cohort Study were 4.6%, 1.7%, and 1.1%, respectively. Being male was associated with an increased risk for ADHD, ASD, and their co-occurrence (aOR 1.30, 1.56, and 1.91, respectively), while higher household income reduced it (aOR 0.82, 0.73, and 0.64). Serious life events during pregnancy (aOR 1.40) and maternal smoking (aOR 1.51) increased the risk of ADHD, while older maternal age (aOR 0.96), higher parental education (aOR 0.72 maternal and aOR 0.74 paternal) and longer exclusive breastfeeding (aOR 0.72) reduced it. Non-Swedish paternal nationality (aOR 0.40) and higher maternal education (aOR 0.74) were associated with a lower risk of ASD, while a family history of autoimmune diseases increased the risk of the co-occurrence of both disorders (aOR 1.62). Obtained results suggest that the etiology of ADHD, ASD, and their co-occurrence is independently associated with environmental psychosocial predictors. The co-occurrence seems to overlap the etiology of ADHD, in which psychosocial determinants have a larger role, however, it is also independently influenced by a family history of autoimmune diseases.

Dissecting heritability, environmental risk, and air pollution causal effects using > 50 million individuals in MarketScan

Large national-level electronic health record (EHR) datasets offer new opportunities for disentangling the role of genes and environment through deep phenotype information and approximate pedigree structures. Here we use the approximate geographical locations of patients as a proxy for spatially correlated community-level environmental risk factors. We develop a spatial mixed linear effect (SMILE) model that incorporates both genetics and environmental contribution. We extract EHR and geographical locations from 257,620 nuclear families and compile 1083 disease outcome measurements from the MarketScan dataset. We augment the EHR with publicly available environmental data, including levels of particulate matter 2.5 (PM2.5), nitrogen dioxide (NO2), climate, and sociodemographic data. We refine the estimates of genetic heritability and quantify community-level environmental contributions. We also use wind speed and direction as instrumental variables to assess the causal effects of air pollution. In total, we find PM2.5 or NO2 have statistically significant causal effects on 135 diseases, including respiratory, musculoskeletal, digestive, metabolic, and sleep disorders, where PM2.5 and NO2 tend to affect biologically distinct disease categories. These analyses showcase several robust strategies for jointly modeling genetic and environmental effects on disease risk using large EHR datasets and will benefit upcoming biobank studies in the era of precision medicine.

Effects of sex, toilet training, stress, and caffeine on nocturnal enuresis among school children in Gondar Town, the metropolitan city of Ethiopia: a community-based study in 2023

Background

Nocturnal enuresis is associated with severe social and psychological problems that affect one's self-esteem, later in life, harmed adolescent and adult life, emotional stress on the family, and poor school performance. Moreover, enuresis children may cause panic attacks, mood disorders, and depression. This study aims to assess the prevalence and associated factors of nocturnal enuresis among children aged 5-14 years in Gondar city, Northwest Ethiopia, 2023.

Methods

A community-based, cross-sectional study was conducted from April 1, 2023, to May 30, 2023. A stratified multistage sampling technique was used to select study subject from kebeles in Gondar city. The data were collected by using a structured, interviewer-administer Questionnaire. The data were entered using EPI DATA version 4.6.02 software, and processed,and analyzed using the statistical package for the social sciences (SPSS) version 25. All variables with P ≤ 0.25 in the bivariate analysis were included in the final model of multivariate analysis. The multivariate binary logistic regression was used to assess the association between the independent and outcome variable. The direction and strength of statistical association were measured with an adjusted odds ratio along with 95% CI and a P-value <0.05 was considered statistically significant.

Result

The overall prevalence of nocturnal enuresis among children aged 5-14 years was 162 (22.2%). The findings showed that being boys [AOR = 0.54; 95% CI (0.31, 0.93)], child and no toilet training practices [AOR = 2.50; 95% CI (1.02, 6.15)], Having no caffeine [AOR = 0.16; 95% CI (0.09, 0.29)], and exposure to stressful events [AOR = 20; 95% CI (11.12, 33.34)] had a significant association with nocturnal enuresis, p-value <0.05.

Conclusion

In this study, the prevalence of nocturnal enuresis children age 5-14 years was higher than that in previous studies. Sex of child, toilet training practices, caffeine c before bed, and presences of stressful event were a significant predictor of nocturnal enuresis.

Aspects of Area Deprivation Index in Relation to Hippocampal Volume Among Children

Importance

Area deprivation index (ADI) has been shown to be associated with reduced hippocampal volume (HV) among youths. The social environment may interact with the association between ADI and HV.

Objective

To investigate which aspects of ADI are uniquely associated with bilateral HV and whether school and family environments have moderating interactions in associations between ADI and HV.

Design, Setting, and Participants

This cross-sectional study used data from the Adolescent Brain and Cognitive Development (ABCD) study. Participants aged 9 and 10 years were recruited from 21 sites in the US between September 2016 and August 2018. Data analysis was performed between March 2023 and April 2024.

Exposures

ADI aspects were derived from participant primary home addresses provided by parents or guardians.

Main Outcomes and Measures

HV was automatically segmented from structural brain images ascertained from magnetic resonance imaging. Multiple generalized linear mixed modeling tested associations between 9 indices of ADI and bilateral HV, with family groups and recruitment sites as random effects. After stepwise backward selection, models were adjusted for individual-level covariates, including age, sex, race and ethnicity, parental education, household income, and estimated intracranial volume.

Results

This study included 10 114 participants aged 9 and 10 years (median [IQR] age, 9.92 [9.33-10.48] years; 5294 male [52.3%]; 200 Asian [2.0%], 1411 Black [14.0%], and 6655 White [65.8%]; 1959 Hispanic [19.4%]). After stepwise backward selection and adjusting for covariates, only the percentage of neighborhood-level single-parent households was associated with right HV (adjusted β per 1-SD increase in single-parent households, -0.03; 95% CI, -0.06 to -0.01; P = .01). School environment interacted with neighborhood-level single-parent households in its association with right HV (adjusted β per 1-SD increase in score, 0.02; 95% CI, 0.01 to 0.03; P = .003), such that there was an inverse association only among those at a school with the mean environment score (adjusted β per 1% increase in single-parent households, -0.03; 95% CI, -0.05 to -0.01; P = .02) and worse (-1 SD score) school environment score (adjusted β per 1% increase in single-parent households, -0.05; 95% CI, -0.09 to -0.01; P < .001) but not among those at better (+1 SD score) school environments.

Conclusions and Relevance

In this study, an increased percentage of neighborhood-level single-parent households was associated with reduced right HV among children in schools with the mean or worse but not better environment score. These findings suggest that longitudinal research concerning the association of neighborhood-level characteristics and school environments with hippocampal development may be warranted to better understand complex interactions between various social factors and child neurodevelopment and mental health outcomes.

Using Life Course Theory to Explore the Association Between Autistic Traits, Child, Family, and School Factors and the Successful Transition to Secondary School

Life Course Theory contends that school transitions can interrupt academic and wellbeing trajectories, depending on child, family, and school factors. Hierarchical regression analyses examined how autistic traits were associated with school transition outcomes. Autistic traits explained 12% of the variance in Quality of Life (QOL), 24% of the variance in mental health and 9% of the variance in school belonging. When autistic traits were accounted for, gender was a significant predictor of changes in QOL whereas changes in school belonging were predicted by cognitive functioning, parent education, school attendance and school refusal. Changes in mental health after transition were mostly predicted by family factors including family structure, family functioning and parent education but were also significantly predicted by sleep problems.

[The Relationship between Social and Family Structures and Behavioral Problems in Preschool Children]

BACKGROUND

Behavioral problems in children are indicators of compromised mental health. Their development is influenced by family and social factors, with limited understanding of interactions among family structure, educational status, migration background, and parental employment concerning behavioral problems. These associations were investigated in children between 5-6 years of age.

METHODS

Data (n=15,271) were collected between 09/2018 and 08/2019 in the federal state of Schleswig-Holstein as part of school entry examinations. Children's behavioral problems were assessed using the Strengths and Difficulties Questionnaire (SDQ). Statistical analyses included descriptive assessments and the calculation of a bivariate logistic regression model, with SDQ's outcomes "problematic" and "non-problematic" as dependent variables, and social and family factors as independent variables (gender, family structure, number of siblings, language proficiency, migration background, parental education level, parental employment, and sports participation in a sports club).

RESULTS

Logistic regression analyses revealed that children living with single parents had a 2.1-fold (odds ratio; OR) higher likelihood [95% confidence interval (CI): 1.7-2.6] of displaying behavioral problems compared to children living with both biological parents. Only children had a 1.4-fold higher likelihood [95% CI: 1.2-1.8] compared to children with one or two siblings. Children with a unilateral migration background exhibited a lower likelihood of behavioral problems [OR: 0.58; 95% CI: 0.38-0.87] than children without a migration background. Children from families with low educational attainment had a 3-fold higher likelihood of behavioral problems [95% CI: 2.3-3.8] compared to those from high educational attainment families. When both parents (or the single parent) were employed at least part-time, there was a lower likelihood of behavioral problems [OR: 0.58; 95% CI: 0.47-0.71] in the child compared to situations where at least one parent was unemployed.

CONCLUSIONS

This study identified sociodemographic factors associated with manifestation of behavioral problems. Particularly, single parents, families with lower educational levels and families with at least one unemployed parent should be targeted for intervention.

Optimising the use of electronic medical records for large scale research in psychiatry

The explosion and abundance of digital data could facilitate large-scale research for psychiatry and mental health. Research using so-called "real world data"-such as electronic medical/health records-can be resource-efficient, facilitate rapid hypothesis generation and testing, complement existing evidence (e.g. from trials and evidence-synthesis) and may enable a route to translate evidence into clinically effective, outcomes-driven care for patient populations that may be under-represented. However, the interpretation and processing of real-world data sources is complex because the clinically important 'signal' is often contained in both structured and unstructured (narrative or "free-text") data. Techniques for extracting meaningful information (signal) from unstructured text exist and have advanced the re-use of routinely collected clinical data, but these techniques require cautious evaluation. In this paper, we survey the opportunities, risks and progress made in the use of electronic medical record (real-world) data for psychiatric research.

An Expanded Conceptual Framework for Understanding Irritability in Childhood: The Role of Cognitive Control Processes

Children prone to irritability experience significant functional impairments and internalising and externalising problems. Contemporary models have sought to elucidate the underlying mechanisms in irritability, such as aberrant threat and reward biases to improve interventions. However, the cognitive control processes that underlie threat (e.g., attention towards threats) and reward (e.g., attention towards reward-related cues) biases and the factors which influence the differential activation of positive and negative valence systems and thus leading to maladaptive activation of cognitive control processes (i.e., proactive and reactive control) are unclear. Thus, we aim to integrate extant theoretical and empirical research to elucidate the cognitive control processes underlying threat and reward processing that contribute to irritability in middle childhood and provide a guiding framework for future research and treatment. We propose an expanded conceptual framework of irritability that includes broad intraindividual and environmental vulnerability factors and propose proximal 'setting' factors that activate the negative valence and positive valence systems and proactive and reactive cognitive control processes which underpin the expression and progression of irritability. We consider the implications of this expanded conceptualisation of irritability and provide suggestions for future research.

Associations between repetitive head impact exposure and midlife mental health wellbeing in former amateur athletes

Introduction

Repetitive head impacts (RHI) have been suggested to increase the risk of developing a neurodegenerative disease, and many of these individuals develop a preceding mental health diagnosis. Given the lack of studies among amateur athletes, this study aimed to examine mental health outcomes in middle-aged amateur athletes who have been exposed to RHI through contact sport participation.

Methods

This is a single site, cohort study involving former amateur athletes aged between 30 and 60 with at least 10 years of organized contact or non-contact sport participation. All participants completed demographic and mental health questionnaires. Mental health outcomes included symptoms related to depression, anxiety, post-traumatic stress disorder (PTSD), attention deficit hyperactive disorder (ADHD), and aggression. Self-reported data on mental health diagnoses and associated prescription were elicited and used to estimate odds ratios (OR).

Results

Data from 41 contact athletes and 22 age/sex-matched non-contact athletes were available for analysis. The contact group exhibited a 2.25-fold higher likelihood of being diagnosed with mental health disorders and 1.29-fold higher likelihood of using associated medications compared to the non-contact group. The contact group reported significantly higher PTSD-related symptoms [4.61 (0.03,9.2), p=0.05] compared to the non-contact control group. While not statistically significant, the contact group showed increased depressive [2.37 (0.05, 4.79), p=0.07] and ADHD symptoms [4.53 (0.51, 9.57), p=0.08] compared to controls. In a secondary analysis, a distinct trend emerged within the contact group, revealing pronounced elevations in mental health symptoms among individuals with lower socioeconomic status (<$50,000/year) compared to higher income subgroups, and these symptoms decreased as income levels rose [depression: -3.08 (-4.47, -1.7), p<0.001; anxiety: -1.95 (-3.15, -0.76), p=0.002; ADHD: -4.99 (-8.28, -1.69), p=0.004; PTSD: -4.42 (-7.28, -1.57), p=0.003; aggression: -6.19 (-11.02, -1.36), p=0.01]. This trend was absent in the non-contact control group.

Discussion

Our data suggest that even individuals at the amateur level of contact sports have an increased likelihood of being diagnosed with mental health disorders or experiencing mental health symptoms compared to non-contact athletes. Our findings indicate that socioeconomic status may have an interactive effect on individuals' mental health, particularly among those with a long history of RHI exposure.

Role of parental educational level as psychosocial factor in a sample of inpatients with anorexia nervosa and bulimia nervosa

Introduction

Evidence on parental educational level (PEL) as a risk factor for Eating Disorders (EDs) is mixed, and no study has assessed its role in relation to the compliance and outcomes of treatments in EDs. Further, no study differentiated from the educational level of mothers and fathers, nor considered the possible mediation of perfectionism in fostering EDs.

Methods

A clinical sample of 242 first-ever admitted inpatients with EDs provided information on PEL and completed the following questionnaires: the Eating Disorder Examination Questionnaire (EDE-Q) and the Frost Multidimensional Perfectionism Scale (F-MPS). Clinicians also provided information on the Hamilton Rating Scale for Anxiety (HAM-A) and the Hamilton Rating Scale for Depression (HAM-D) for each participant.

Results

Individuals with high PEL (whether mothers, fathers, or both parents) showed significantly higher scores on depressive symptoms and lower on parental criticism, were younger, had an earlier age of onset, had fewer years of illness, more were students and employed, and fewer had offspring. Individuals with fathers or both parents with high educational levels suffered more from Anorexia Nervosa rather than Bulimia Nervosa, had a longer length of stay during the current hospitalization, had less dietary restraint, and had higher personal standards. Individuals with mothers with high educational levels showed a lower rate of previous substance or alcohol addiction. Personal standards partially mediated the relationship between higher PEL and lower dietary restraint.

Discussion

PEL emerged to be a twofold psychosocial risk factor, being associated with higher depressive symptoms and a longer length of stay, but also with a shorter duration of illness and better scholar and working involvement. Higher PEL was related to higher personal standards but not to global perfectionism. Patterns of eating psychopathology emerged based on the high PEL of mothers or fathers.

The epidemiology of major depression among adults in Norway: an observational study on the concurrence between population surveys and registry data - a NCDNOR project

BACKGROUND

Mental health problems, and major depression in particular, are important public health issues. Following trends in the prevalence of major depression is difficult because of the costs and complications of diagnostic interviews and general population self-report health surveys. Scandinavian countries, however, have several central, population-based health registries. We aimed to investigate how well these registries capture the epidemiology of major depression in the population.

METHODS

In two Norwegian regional surveys of general population health, each repeated after 10 years, responders were asked to report depressive symptoms using the Hopkins Symptom Checklist (HSCL) or the Hospital Anxiety and Depression Scale (HADS). Data were linked to three central health registries capturing contact with primary care, specialist care and prescriptions for antidepressants, to investigate how well these registries reflected self-reported depressive symptoms.

RESULTS

Most responders scored low on Hopkins Symptom Checklist (HSCL) and the Hospital Anxiety and Depression Scale (HADS), but 10% and 13%, respectively, scored above cut-off, with only minor changes between the two survey times. Females scored higher than males. Older people scored lower than younger, and a social gradient was visible. Around 12% of those who scored above the cut-off on either scale were recorded in the central health registries during the following year. This correlation was highest in primary care data, followed by prescription data and lowest in specialist care. Females were more often recorded in registries (p < 0.001), as were younger people (p < 0.001).

CONCLUSIONS

There was a strong association between scores on screening for major depression in the general population surveys and being recorded in central health registries. There was a low sensitivity of these registries. and there was some variation in how sensitive the central health registries were in picking up depression, especially for males and older people. However, the stability of the measures over time suggests we may get an impression of the prevalence of major depression in the general population by using data from the central health registries. A combination of primary care data, prescription data and specialist care data have a higher sensitivity.

Grill-Related Burn Injuries: A Matched Cohort Study

Barbequing can result in devastating burn injuries with unsafe practices. This study aims to characterize the demographics, injury characteristics, and outcomes of grill-related burns and identify ways of burn prevention. A retrospective review of patients admitted to a single-institution, metropolitan burn center from January 1, 2017, to July 1, 2023. Data included demographics, burn injury characteristics, and outcomes. Each Grill Cohort patient was matched to 3 nongrill controls by mBaux score and burn location. Of 2355 patients, 69 (2.9%) met Grill Cohort inclusion criteria. The Grill Cohort had 55 (79.7%) males and an average age of 41.7 ± 17.5 years old. In the Grill Cohort, 25 (36.2%) patients had positive blood alcohol, 8 (11.6%) tested positive for amphetamines, and 5 (7.2%) for cocaine at the time of admission. A total of 61 (88.4%) Grill Cohort burns involved the upper extremity, 43 (62.3%) the head/neck, 34 (49.3%) the lower extremity, and 30 (43.5%) the trunk. Compared with the Control Cohort, the Grill Cohort had smaller proportions of patients who were undomiciled (P < .01) or had a history of mental illness (P < .001). Grill-related burns had a greater proportion of flash/flame burns (P < .001). This study suggests that middle-aged, domiciled males without psychiatric comorbidities are more likely to make preventable grilling errors resulting in burn injuries. Prevention strategies targeting this demographic group should emphasize the risks of grilling while intoxicated, proper handling of propane tanks and lighter fluid, and the use of flash/flame-resistant gear protecting the upper extremities and head/neck.

A systematic review exploring characteristics of youth with severe and enduring mental health problems (SEMHP)

A small group of youth and emerging adults deals with severe and enduring mental health problems (SEMHP). Current mental health care struggles to recognize and treat this group timely and adequately, leaving these youth between the cracks of the system. A first step to improve care for this group is to gain a deeper understanding of the characteristics of youth with SEMHP. Therefore, this study aimed at reviewing current literature about this target group and what is known so far about their characteristics. We included 39 studies with a focus on youth aged 12-25 years with SEMHP. After critical appraisal, a content analysis and in-depth thematic analysis were conducted. According to the included studies, youth with SEMHP were characterized by severe distress and recurrent comorbid mental health problems, with pervasive suicidality. Further, underlying trauma, family conflicts, peer rejection, deep feelings of hopelessness, and psychosocial malfunctioning characterized SEMHP. It was described that for youth with SEMHP a pervasive pattern of dysfunction in multiple domains is present leading to a detrimental impact. Subsequently, this pattern exerts a reciprocal influence on the mental health problems, causing a vicious circle further worsening SEMHP. Our findings emphasize the need for a holistic approach and to look beyond the traditional classification system in order to meet the needs of these youth with wide-ranging comorbid mental health problems.

Adolescent suicide risk factors and the integration of social-emotional skills in school-based prevention programs

Adolescents are considered one of the most vulnerable groups affected by suicide. Rapid changes in adolescents' physical and mental states, as well as in their lives, significantly and undeniably increase the risk of suicide. Psychological, social, family, individual, and environmental factors are important risk factors for suicidal behavior among teenagers and may contribute to suicide risk through various direct, indirect, or combined pathways. Social-emotional learning is considered a powerful intervention measure for addressing the crisis of adolescent suicide. When deliberately cultivated, fostered, and enhanced, self-awareness, self-management, social awareness, interpersonal skills, and responsible decision-making, as the five core competencies of social-emotional learning, can be used to effectively target various risk factors for adolescent suicide and provide necessary mental and interpersonal support. Among numerous suicide intervention methods, school-based interventions based on social-emotional competence have shown great potential in preventing and addressing suicide risk factors in adolescents. The characteristics of school-based interventions based on social-emotional competence, including their appropriateness, necessity, cost-effectiveness, comprehensiveness, and effectiveness, make these interventions an important means of addressing the crisis of adolescent suicide. To further determine the potential of school-based interventions based on social-emotional competence and better address the issue of adolescent suicide, additional financial support should be provided, the combination of social-emotional learning and other suicide prevention programs within schools should be fully leveraged, and cooperation between schools and families, society, and other environments should be maximized. These efforts should be considered future research directions.

Health inequalities in childhood diseases: temporal trends in the inter-crisis period

BACKGROUND

Since 2008, children in Catalonia (Spain) have suffered a period of great economic deprivation. This situation has generated broad-ranging health inequalities in a variety of diseases. It is not known how these inequalities have changed over time. The aim of the present study is to determine trends in inequalities over this period in ten relevant diseases in children according to sex and age.

METHODS

A retrospective cross-sectional population-based study of all children under 15 years old resident in Catalonia during the 2014-2021 period (over 1.2 million children/year) and of their diagnoses registered by the Catalan Health System. Health inequalities were estimated by calculating the relative index of inequality and time trends using logistic regression models. Interaction terms were added to test for the effects of sex on time trends.

RESULTS

Increasing significant temporal trends in inequalities were shown for both sexes in almost all the diseases or adverse events studied (asthma, injuries, poisoning, congenital anomalies, overweight and obesity), in mood disorders in boys, and in adverse birth outcomes in girls. Adjustment and anxiety and mood disorders in girls showed a decreasing temporal trend in inequalities. More than half of the diseases and adverse events studied experienced significant annual increases in inequality. Poisoning stood out with an average annual increase of 8.65% [4.30, 13.00], p ≤ 0.001 in boys and 8.64% [5.76, 11.52], p ≤ 0.001) in girls, followed by obesity with increases of 5.52% [4.15, 6.90], p =  < 0.001 in boys and 4.89% [4.26, 5.51], p ≤ 0.001) in girls.

CONCLUSIONS

Our results suggest that inequalities persist and have increased since 2014. Policy makers should turn their attention to how interventions to reduce Health inequalities are designed, and who benefits from them.

Influence of early childhood parental hostility and socioeconomic stress on children's internalizing symptom trajectories from childhood to adolescence

Introduction

Children and adolescents with elevated internalizing symptoms are at increased risk for depression, anxiety, and other psychopathology later in life. The present study examined the predictive links between two bioecological factors in early childhood-parental hostility and socioeconomic stress-and children's internalizing symptom class outcomes, while considering the effects of child sex assigned at birth on internalizing symptom development from childhood to adolescence.

Materials and Methods

The study used a sample of 1,534 children to test the predictive effects of socioeconomic stress at ages 18 and 27 months; hostile parenting measured at child ages 4-5; and sex assigned at birth on children's internalizing symptom latent class outcomes at child ages 7-9, 10-12, 13-15, and 16-19. Analyses also tested the mediating effect of parenting on the relationship between socioeconomic stress and children's symptom classes. Other covariates included parent depressive symptoms at child ages 4-5 and child race and ethnicity.

Results

Analyses identified three distinct heterogenous internalizing symptom classes characterized by relative symptom levels and progression: low (35%); moderate and increasing (41%); and higher and increasing (24%). As anticipated, higher levels of parental hostility in early childhood predicted membership in the higher and increasing symptom class, compared with the low symptom class (odds ratio (OR) = .61, 95% confidence interval (CI) [.48,.77]). Higher levels of early childhood socioeconomic stress were also associated with the likelihood of belonging to the higher-increasing symptom class compared to the low and moderate-increasing classes (OR = .46, 95% CI [.35,.60] and OR = .56, 95% CI [.44,.72], respectively). The total (c = .61) and direct (c' = .57) effects of socioeconomic stress on children's symptom class membership in the mediation analysis were significant (p <.001).

Discussion

Study findings suggest that intervening on modifiable bioecological stressors-including parenting behaviors and socioeconomic stressors-may provide important protective influences on children's internalizing symptom trajectories.

Mental health among adolescents exposed to social inequality in Latin America and the Caribbean: a scoping review

Background and objective

Adolescents from Latin America and the Caribbean grow up in a context of social inequality, which diminishes their well-being and leads to impaired emotional-cognitive development. To understand the problem, it is important to synthesize the available research about it. This study aims to explore the knowledge about adolescents' mental health in Latin America and the Caribbean exposed to social inequality.

Methods

A systematic scoping review was conducted encompassing a search in five databases (Medline, CINAHL, PsycINFO, Scopus, and LILACS) in June 2022. Articles of various typologies were included without time limit. After two rounds of screening, relevant data were manually extracted and synthesized into self-constructed themes using thematic analysis.

Results

Out of 8,825 retrieved records, 42 papers were included in the final review, with a predominance of quantitative approaches. The synthesis revealed two main analytical themes: (a) defining social inequality, wherein intersecting inequalities produce discrimination and determine conditions for social vulnerability; (b) social inequality and mental health, which highlights the association between socio-structural difficulties and emotional problems, amplifying vulnerability to mental ill health and poor mental health care.

Conclusion

The scientific evidence reveals that social inequality is related to impaired well-being and mental ill health on the one hand and a lack of access to mental health care on the other hand.

Socioeconomic and gender inequalities in mental disorders among adolescents and young adults

BACKGROUND

Socioeconomic status (SES) and gender play a key role in mental health. The objective of this study was to assess socioeconomic and gender mental health inequalities in adolescents and young adults using a population-based registry.

MATERIALS AND METHODS

We conducted a lifetime follow-up study of all residents in the Basque Country between 1 and 30 years old (n=609,381) as of 31 December 2018. Primary care, specialized outpatient, and hospital care records were searched for diagnoses. SES was assessed based on household income. We estimated disaggregated lifetime prevalence of substance use, behaviour, anxiety, depression, psychosis, and attention deficit hyperactivity disorder. The local Institute of Statistics validated the mortality data. The likelihood of risks was estimated using logistic regression.

RESULTS

Overall, 96,671 individuals (15.9%) had a diagnosed mental disorder, with clear gradients by gender and SES. Females of medium-to-high SES had the lowest prevalence of all mental disorders, except anxiety and depression. This group was followed by males of the same SES and females of low SES, while the highest prevalence of mental disorders was observed in low-SES males. The lower income categories had higher risks of psychiatric admission (adjusted odds ratio [AOR]: 3.64 for females; 6.66 for males) and death (AOR: 5.42). People with a mental health diagnosis had higher mortality (AOR: 2.38).

CONCLUSIONS

Our work evidenced important SES and gender inequalities in the mental health and premature mortality of adolescents and young adults, findings that should drive the development and implementation of early preventive interventions.

Longitudinal associations between socioeconomic status and psychosocial problems in preschool children

Socioeconomic status (SES) at different points in a child's lifetime may have different effects on health outcomes. This study aimed to examine longitudinal associations between SES and psychosocial problems in preschool children (n = 2509, Mage = 24.2 ± 1.3 months). The psychosocial problems of children were assessed using the Brief Infant-Toddler Social and Emotional Assessment at age 2 years and age 3 years and categorized as having yes/no psychosocial problems. Four groups of pattern of presence/absence of psychosocial problems between age 2 and 3 years were classified: (1) 'no problems', (2) 'problems at age two', (3) 'problems at age three', and (4) 'continuing problems'. Five indicators of SES (i.e., maternal education level, single-parent family, unemployment, financial problems, and neighborhood SES) were evaluated. Results showed around one-fifth (2Y = 20.0%, 3Y = 16.0%) of children had psychosocial problems. Multinomial logistic regression models revealed low and middle maternal education levels were associated with 'problems at age two'; low maternal education level and financial problems were associated with 'problems at age three'; low and middle maternal education level, single-parent family, and unemployment were associated with 'continuing problems'. No associations were observed between neighborhood SES and any pattern. Results suggest children in a lower SES, indicated by maternal education, single-parent family, and financial stress, had higher odds of developing and continuously having psychosocial problems in early childhood. These findings call for optimally timing interventions to reduce the impact of disadvantaged SES in early childhood on psychosocial health.

Are social pressure, bullying and low social support associated with depressive symptoms, self-harm and self-directed violence among adolescents? A cross-sectional study using a structural equation modeling approach

BACKGROUND

More in-depth evidence about the complex relationships between different risk factors and mental health among adolescents has been warranted. Thus, the aim of the study was to examine the direct and indirect effects of experiencing social pressure, bullying, and low social support on mental health problems in adolescence.

METHODS

A school-based cross-sectional study was conducted in 2022 among 15 823 Norwegian adolescents, aged 13-19 years. Structural Equation Modelling was used to assess the relationships between socioeconomic status, social pressure, bullying, social support, depressive symptoms, self-harm and suicide thoughts.

RESULTS

Poor family economy and low parental education were associated with high pressure, low parental support and depressive symptoms in males and females. Moreover, poor family economy was associated with bullying perpetration and bullying victimization among males and females, and cyberbullying victimization among females, but not males. Low parental education was associated with bullying victimization among males, but not females. Further, high social pressure was associated with depressive symptoms among males and females, whereas high social pressure was linked to self-harm and suicide thoughts among females, but not males. Bullying victimization and cyberbullying victimization were associated with depressive symptoms, self-harm, and suicide thoughts among males and females. Bullying victimization was associated with depressive symptoms among males, but not females, whereas bullying perpetration was linked to self-harm and suicide thoughts among females, but not males. Low parental support was associated with bullying perpetration, bullying victimization, depressive symptoms, self-harm and suicide thoughts among males and females, whereas low parental support was associated with high social pressure among females, but not males. Low teacher support was associated with high social pressure and depressive symptoms. Low support from friends was associated with bullying victimization, depressive symptoms and suicide thoughts among males and females, whereas low support from friends was linked to self-harm among males, but not females. Finally, results showed that depressive symptoms were associated with self-harm and suicide thoughts among males and females.

CONCLUSION

Low socioeconomic status, social pressure, bullying and low social support were directly and indirectly associated with depressive symptoms and self-directed violence among Norwegian adolescents.

The comparative study of chronically ill and healthy children and adolescents in the light of their general mental health

Children's hospitalisation is difficult for the family and the immediate environment. In these cases, the provision of psychological support is particularly important. Chronically ill children who are regularly hospitalised are in a particularly difficult situation, often feeling vulnerable. Our research aims to explore and analyse in detail the psychological state, attitudes and mental health of chronically ill children and to compare patient groups (children receiving care in pulmonology, gastroenterology, onco-haematology and rehabilitation) to understand the interacting factors, which may be of great importance for quality patient care and for measures to improve patient care in the future. We studied chronically ill children (N = 107) aged 10 to 18 years (M = 14.3; SD = 2.0), cared for by the Department of Paediatric Rehabilitation, Paediatric Psychiatry and Psychosomatics of the University of Debrecen Clinical Centre, the second largest paediatric institution in Hungary. In our survey, sociodemographic questions, the Connor-Davidson Resilience Scale, the Satisfaction With Life Scale, the Cantril Ladder, the Non-Productive Thoughts Questionnaire, the Problematic Internet Use Questionnaire, the Drawing version of Pictorial Representation of Illness Self-Measure (PRISM-D), the Beck Depression Inventory-Shortened Scale, the Illness Intrusiveness Ratings Scale, the Spielberger State-Trait Anxiety Questionnaire-Child Version and the Strength and Difficulty Questionnaire were applied. One-way analysis of variance (ANOVA) was used to examine differences between groups, and Pearson rank correlation analysis was used to measure the relationships between individual variables. The results show significant differences between patient groups in terms of resilience, depression, nonproductive thoughts, problematic internet use, anxiety and coping, but no consistent pattern in the development of scores. In addition, for some psychological correlates, the role of sociodemographic background also showed significant results. The practical utility of our study is that using questionnaire methods to map patient satisfaction, compliance, and patient attitudes will provide regarding the factors that influence the mental health status of children living with chronic illnesses. In the light of this, additional methods and tools can be included to improve the quality of healthcare and to develop a set of procedures that will serve the intended purpose.

Global topology of human connectome is insensitive to early life environments - A prospective longitudinal study of the general population

The widely acknowledged detrimental impact of early adversity on child development has driven efforts to understand the underlying mechanisms that may mediate these effects within the developing brain. Recent efforts have begun to move beyond associating adversity with the morphology of individual brain regions towards determining if and how adversity might shape their interconnectivity. However, whether adversity effects a global shift in the organisation of whole-brain networks remains unclear. In this study, we assessed this possibility using parental questionnaire and diffusion imaging data from The Avon Longitudinal Study of Parents and Children (ALSPAC, N = 913), a prospective longitudinal study spanning more than 20 years. We tested whether a wide range of adversities-including experiences of abuse, domestic violence, physical and emotional cruelty, poverty, neglect, and parental separation-measured by questionnaire within the first seven years of life were significantly associated with the tractography-derived connectome in young adulthood. We tested this across multiple measures of organisation and using a computational model that simulated the wiring economy of the brain. We found no significant relationships between early exposure to any form of adversity and the global organisation of the structural connectome in young adulthood. We did detect local differences in the medial prefrontal cortex, as well as an association between weaker brain wiring constraints and greater externalising behaviour in adolescence. Our results indicate that further efforts are necessary to delimit the magnitude and functional implications of adversity-related differences in connectomic organization. RESEARCH HIGHLIGHTS: Diverse prospective measures of the early-life environment do not predict the organisation of the DTI tractography-derived connectome in young adulthood Wiring economy of the connectome is weakly associated with externalising in adolescence, but not internalising or cognitive ability Further work is needed to establish the scope and significance of global adversity-related differences in the structural connectome.

Interplay of socioeconomic status, cognition, and school performance in the ABCD sample

Coming from a disadvantaged background can have negative impact on an individual's educational trajectory. Some people however seem unaffected and cope well with the demands and challenges posed by school education, despite growing up in adverse conditions, a phenomenon termed academic resilience. While it is uncertain which underlying factors make some people more likely to circumvent unfavorable odds than others, both socioeconomic status (SES) and cognitive ability have robustly been linked to school performance. The objective of the present work is to investigate if individual cognitive abilities and SES interact in their effect on grades. For this purpose, we analyzed SES, cognitive, and school performance data from 5001 participants from the Adolescent Brain Cognitive Development (ABCD) Study. Ordinal logistic regression models suggest similar patterns of associations between three SES measures (parental education, income-to-needs ratio, and neighborhood deprivation) and grades at two timepoints, with no evidence for interaction effects between SES and time. Parental education and income-to-needs ratio were associated with grades at both timepoints, irrespective of whether cognitive abilities were modeled or not. Neighborhood deprivation, in contrast, was only a statistically significant predictor of reported grades when cognitive abilities were not factored in. Cognitive abilities interacted with parental education level, meaning that they could be a safeguard against effects of SES on school performance.

What characterizes adolescent young carers? A multigroup comparative study

CONTEXT

To identify the characteristics of adolescent young carers (AYCs), studies in the literature have compared them with non-AYCs, but without considering that in the latter group, some face the illness of a relative whereas others do not.

OBJECTIVES

The aims of the study were (1) to identify the characteristics of AYCs as compared with adolescents who are not young carers but are facing the illness/disability of a relative, or adolescents not facing the illness/disability of a relative, and (2) to identify factors associated with being a carer within adolescents facing a relative illness.

METHODS

A total of 4000 high school students (grades 10-12, mainly aged 15-17 years, 568 identified as AYCs, 1200 as adolescents facing the illness/disability of a relative without being a carer and 2232 as adolescents not facing the illness/disability of a relative) completed a self-reported questionnaire assessing sociodemographic characteristics, illness/disability in the family, caregiving activities (MACA-YC18 and specific emotional support scale), quality of life (KIDSCREEN-10) and mental health (GHQ-12). Chi-square tests, ANOVAs and logistic regressions were performed.

RESULTS

AYCs scored lower on the quality-of-life measure compared with adolescents not facing the illness/disability of a relative (p < .001) and had poorer mental health compared with adolescents facing the illness/disability of a relative without being a carer and adolescents not facing the illness/disability of a relative (p < .001). Logistic regressions showed that youth were more at risk to be an AYC when they were females (p < .001), when they had an extracurricular job (p < .001), spoke another language at home (p < .01), had siblings and were one of the oldest siblings (p < .001), and when the relative had a serious or chronic physical illness (p < .001) and lived with the youth (p < .001).

CONCLUSIONS

These results highlight the importance of distinguishing AYCs, adolescents facing the illness/disability of a relative without being a carer and adolescents not facing the illness/disability of a relative to better describe AYCs, recognizing that as the level of care provided might change over time, adolescents facing the illness/disability of a relative without being a carer could become AYCs or inversely. The factors that emerged could be used by professionals to better identify AYCs.

The impact of past childhood adversity and recent life events on neural responses during fear conditioning

BACKGROUND AND PURPOSE

Many studies have shown that exposure to life events can have a negative impact on mental health. Life events like the death of a spouse or the birth of a child pose a challenge and require temporal or permanent adjustments. Meta-analyses on brain stress responses found bilateral anterior insula activation in response to acute stress. Fear conditioning is assumed a crucial mechanism for the development of anxiety disorders associated with increased activation in the bilateral amygdala. Empirical evidence is lacking regarding the relationship of exposure to recent life events and past childhood adversity with neural processing during fear conditioning.

METHODS

In the present study, we analyzed data from 103 young, healthy participants. Multiple linear regressions were performed on functional magnetic resonance imaging activation during fear conditioning with the Life Events Scale for Students and the Childhood Trauma questionnaire included as covariates in two separate models.

RESULTS

We found a positive relationship between the number of life events in the last year and left amygdala activation to the conditioned stimulus. A second finding was a positive relationship between childhood adversity and right anterior insula response to the unconditioned stimulus.

CONCLUSIONS

Many studies have shown increased amygdala activity after stressful life events. In addition, the anterior insula is activated during acute stress. The present study points to stressor-induced increased salience processing during fear conditioning. We suggest that this could be a potential mechanism for resilience versus mental illness.

Children Fleeing War-Exploring the Mental Health of Refugee Children Arriving in Israel after the Ukraine 2022 Conflict

BACKGROUND

In February 2022, Ukraine suffered a devastating assault by Russia, leading to destruction, casualties, and mass displacement. Among those displaced were over 1.5 million children. Forced displacement exposes children to a heightened risk of mental health issues.

OBJECTIVE

This study investigated the prevalence of Post-traumatic stress disorder (PTSD) and other mental health issues among child refugees shortly after their displacement from Ukraine to Israel. It aimed to identify factors influencing PTSD development and explore their associations.

METHODS

The study included 59 child refugees who had arrived in Israel after fleeing the war in Ukraine. Parents completed self-report questionnaires to assess their children's mental health.

RESULTS

Only three children met the DSM diagnostic criteria for PTSD, with higher scores in the negative cognition and re-experiencing clusters. Over half of the children exhibited general mental health problems, with approximately 40 % showing internalizing problems, and 30 % showing externalizing problems. The study also found a significant comorbidity between PTSD symptoms and internalizing problems. Additionally, internalizing problems emerged as the sole significant predictor of PTSD levels when considering factors such as age, gender, economic status, parents' work status, internalizing problems, and externalizing problems.

CONCLUSIONS

Child refugees frequently experience psychological distress, even if they do not meet the formal diagnostic criteria for PTSD. They often exhibit other distress symptoms, primarily internalizing problems, which can be challenging to detect. A deeper understanding of the challenges faced by refugee children can inform the development of targeted assistance programs and the recruitment and training of personnel in host countries.

Burden and Epidemiology of Mental Disorders in the Middle East and North Africa from 1990 to 2019: Findings from the Global Burden of Disease Study

Background

Previous studies have mainly focused on individual mental disorders, and there is no study addressing the total burden of mental disorders in the Middle East and North Africa (MENA).

Aims

To evaluate the burden of mental disorders in the MENA region from 1990 to 2019.

Study Design

A cross-sectional study.

Methods

We utilized global burden of disease data to examine the burden of 12 mental disorders from 1990 to 2019 across age groups, genders, and the 21 MENA countries. We collected data on prevalence, incidence, mortality, years of life lost, years lived with disability, and disability-adjusted life-years (DALY), including both crude and age-standardized rates per 100,000 people.

Results

The DALY rate of mental disorders in MENA countries increased by 13.88% from 1,747.92 per 100,000 people in 1990 to 1990.5 per 100,000 people in 2019. The highest percentage increases in the DALY rates of mental disorders were observed for bulimia nervosa (35.69%), other mental health disorders (34.58%), and schizophrenia (33.02%) from 1990 to 2019. However, the DALY rates for idiopathic developmental intellectual disability (-26.48%), conduct disorder (-23.91%), attentiondeficit/ hyperactivity disorder (-16.46%), and autism spectrum disorders (-4.12%) decreased in the MENA region from 1990 to 2019. In 2019, the highest DALY rates for idiopathic developmental intellectual disability, anxiety disorders, and major depressive disorder were observed in age groups ≤ 4 years, 5-19 years, and ≥ 20 years, respectively. The age-standardized DALY rate of mental disorders was the highest in Palestine (2,396.9 per 100,000), Iran (2,295.8 per 100,000), and Lebanon (2,126.0 per 100,000) compared with other MENA countries in 2019.

Conclusion

There has been a slight increase in the burden of mental disorders in the MENA region between 1990 and 2019. National policies should prioritize evidence-based preventive measures and ensure accessible treatment options for mental health disorders in the population, especially in the MENA region.

Early resource scarcity causes cortical astrocyte enlargement and sex-specific changes in the orbitofrontal cortex transcriptome in adult rats

Astrocyte morphology affects function, including the regulation of glutamatergic signaling. This morphology changes dynamically in response to the environment. However, how early life manipulations alter adult cortical astrocyte morphology is underexplored. Our lab uses brief postnatal resource scarcity, the limited bedding and nesting (LBN) manipulation, in rats. We previously found that LBN augments maternal behaviors and promotes later resilience to adult addiction-related behaviors, reducing impulsivity, risky decision-making, and morphine self-administration. These behaviors rely on glutamatergic transmission in the medial orbitofrontal (mOFC) and medial prefrontal (mPFC) cortex. Here we tested whether LBN changed astrocyte morphology in the mOFC and mPFC of adult rats using a novel viral approach that, unlike traditional markers, fully labels astrocytes. Prior exposure to LBN causes an increase in the surface area and volume of astrocytes in the mOFC and mPFC of adult males and females relative to control-raised rats. We next used bulk RNA sequencing of OFC tissue to assess transcriptional changes that could increase astrocyte size in LBN rats. LBN caused mainly sex-specific changes in differentially expressed genes. Pathway analysis revealed that OFC glutamatergic signaling is altered by LBN in males and females, but the gene changes in that pathway differed across sex. This may represent a convergent sex difference where glutamatergic signaling, which affects astrocyte morphology, is altered by LBN via sex-specific mechanisms. Collectively, these studies highlight that astrocytes may be an important cell type that mediates the effect of early resource scarcity on adult brain function.

The Urban-Rural Difference in Child Mental Health in Vietnam: The Continuing Impacts of the COVID-19 Pandemic on Health

OBJECTIVES

We aimed to explore the difference between rural and urban children's mental health and quality of life after the pandemic.

METHODS

A total of 200 parents and their 11- to 15-year-old children were interviewed face to face in October 2022. This study measures child mental health and quality of life using the Strengths and Difficulties Questionnaire and Child Health Utility 9 Dimensions tools. The unadjusted effect sizes on health outcomes among demographic groups are calculated using Cohen's d. The school-specific fixed effects linear regression model with bootstrapped standard errors is applied.

RESULTS

Rural children have significantly higher mean internalizing behavior scores than urban children (emotional problems, Cohen's d score = 0.38; peer difficulties, Cohen's d score = 0.39; P < .05). Although children living in urban areas who had COVID-19 had significantly higher peer problem scores (Cohen's d score = 0.82, P < .05), the result was not found in those residing in rural areas. After controlling all variables, the econometrics method confirms that infection status significantly affects children's peer problems, obviously in the urban sample.

CONCLUSIONS

Children may experience the consequences of the pandemic on their mental health related to peer difficulties, differently between urban and rural areas. Further research is required to investigate the different impacts of COVID-19 on health in urban and rural areas.

Neighbourhood characteristics and socioeconomic inequalities in child mental health: Cross-sectional and longitudinal findings from the Growing Up in Ireland study

This study examined the role of neighbourhood characteristics in explaining socioeconomic inequalities in child mental health (the total difficulties score from the Strengths and Difficulties Questionnaire) using data from Cohort '08 of Growing Up in Ireland Waves 3 (age 5; baseline) and 5 (age 9; follow-up). Twenty neighbourhood items were grouped into neighbourhood safety, built environments, cohesion, interaction, and disorder. Data were analysed using regression, single and multiple mediation, and network psychometric analyses. We found that neighbourhood safety, cohesion, interaction, and disorder were associated with child mental health. These four domains separately (by up to 18 %) or in concert (by up to 23 %) partially explained socioeconomic inequalities in child mental health. Built environments may explain socioeconomic inequalities in mental health in urban children only. Findings from network analysis indicated that specific concerns over "people being drunk or taking drugs in public" and "this is a safe neighbourhood" had the strongest connections with child mental health. Improving neighbourhood characteristics may be important to reduce socioeconomic inequalities in child mental health in Ireland.

Perceived discrimination as a mediator between cultural identity and mental health symptoms among racial/ethnic minority adults in the United States: insights from the Health Information National Trends Survey 6

OBJECTIVE

This study examined the role of perceived discrimination as a mediator between cultural identity and mental health symptoms among adults from racial/ethnic minority groups in the United States.

METHODS

Data were gathered from the National Cancer Institute's (NCI) Health Information National Trends Survey (HINTS) 6, a nationally representative survey. The mediating role of perceived discrimination was investigated using structural equation modeling (SEM) analysis.

RESULTS

The study found significant associations between demographic and lifestyle factors and mental health symptoms. Non-Hispanic Blacks or African Americans and Hispanics were less likely than Non-Hispanic Whites to have mental health symptoms. Individuals between the ages of 35 and 49, 50 to 64, 65 to 74, and 75 and older had lower odds of mental health symptoms. Gender differences revealed that females had a higher risk of mental health issues than males. Socioeconomic factors, such as household income and employment status, played a significant role, with higher household income and employment status being associated with a decreased likelihood of mental health symptoms. The study emphasizes the role of perceived discrimination as a mediator, suggesting that it fully mediated the association between cultural identity and mental health symptoms. These findings highlight the significance of addressing discrimination experiences in fostering the mental health of adults from diverse backgrounds.

CONCLUSION

The findings highlight the need to take racial, ethnic, and socioeconomic inequities, as well as cultural identity and prejudice, into account in mental health research and interventions. The identified risk and protective factors can guide interventions and policies to enhance this population's mental health.

Exploration of the factors influencing the quality of life among adolescents during the COVID-19 pandemic: the data from a cross-sectional study in Shandong

BACKGROUND

The COVID-19 pandemic has sparked unprecedented transformations in the lives of adolescents, with reshaping their routines, social dynamics, educational experiences, and overall well-being. Our study delves into the influence of various factors on adolescents' quality of life (QOL) among the COVID-19 pandemic in Shandong Province, China.

METHODS

Employing a cross-sectional research approach combined with multivariable analysis, we scrutinize the association of demographic factors (age, gender, education level, ethnic groups, urban area, and family economic status) and health-related behaviors (sleep duration, and self-reported health status) with QOL in 9953 students.

RESULTS

During the pandemic, the average QOL for adolescents in Shandong Province was 133. Our analysis revealed that sleep duration and age had statistically significant associations with total QOL, with the OR values of 1.43 (95% confidence interval (CI): 1.03 to 1.83) and 0.44 (95% CI: 0.19 to 0.70), respectively. Notably, we observed that adolescents from economically disadvantaged families, or those with poorer self-reported health status, were more likely to report lower QOL scores.

CONCLUSIONS

Overall, our study highlights the potential association of sleep duration, age, family economic status, and self-reported health with the QOL of adolescents in Shandong Province during the pandemic. During similar public health crises, policymakers, educators, and healthcare providers can actively work through resource allocation and effective intervention measures towards alleviating financial burdens, improving health conditions, and ultimately enhancing the total QOL for adolescents.

Socioeconomic inequalities in child and adolescent mental health in Australia: the role of parenting style and parents' relationships

BACKGROUND

Socioeconomic inequalities in health and their determinants have been studied extensively over the past few decades. However, the role of parenting style and parents' couple relationships in explaining mental health inequalities is limited. Therefore, this study aims to investigate the distributional impact of parenting style (angry parenting, consistent parenting, and inductive parenting) and parents' couple relationships (e.g., argumentative, happy relationships) on socioeconomic inequalities and by extension on mental health status of Australian children and adolescents.

METHODS

This study utilized data from the Longitudinal Study of Australian Children (Waves 1-7), specifically focusing on intact biological parent families, while excluding single-parent and blended-family households. We applied the decomposition index and the Blinder Oaxaca method to investigate the extent of the contribution and temporal impact of parenting style and parents' couple relationships on the mental health status of Australian children and adolescents.

RESULTS

This study revealed that poor parenting style is the single most important factor that leads to developing mental health difficulties in children and adolescents, especially from low socioeconomic status, and it contributes almost 52% to socioeconomic inequalities in mental health status. Conversely, household income, maternal education, employment status, and parents' couple relationships contributed 28.04%, 10.67%, 9.28%, and 3.34%, respectively, to mental health inequalities in children and adolescents.

CONCLUSION

Overall, this study underscores the importance of parenting style and parents' couple relationships as significant predictors of mental health outcomes in children and adolescents. These results highlight the need for targeted interventions to support families from low socioeconomic backgrounds to address the significant mental health inequalities observed in the study population.

Making Connections: Neurodevelopmental Changes in Brain Connectivity After Adverse Experiences in Early Adolescence

Adverse childhood experiences have been linked to detrimental mental health outcomes in adulthood. This study investigates a potential neurodevelopmental pathway between adversity and mental health outcomes: brain connectivity. We used data from the prospective, longitudinal Adolescent Brain Cognitive Development (ABCD) study (N ≍ 12.000, participants aged 9-13 years, male and female) and assessed structural brain connectivity using fractional anisotropy (FA) of white matter tracts. The adverse experiences modeled included family conflict and traumatic experiences. K-means clustering and latent basis growth models were used to determine subgroups based on total levels and trajectories of brain connectivity. Multinomial regression was used to determine associations between cluster membership and adverse experiences. The results showed that higher family conflict was associated with higher FA levels across brain tracts (e.g., t (3) = -3.81, β = -0.09, p bonf = 0.003) and within the corpus callosum (CC), fornix, and anterior thalamic radiations (ATR). A decreasing FA trajectory across two brain imaging timepoints was linked to lower socioeconomic status and neighborhood safety. Socioeconomic status was related to FA across brain tracts (e.g., t (3) = 3.44, β = 0.10, p bonf = 0.01), the CC and the ATR. Neighborhood safety was associated with FA in the Fornix and ATR (e.g., t (1) = 3.48, β = 0.09, p bonf = 0.01). There is a complex and multifaceted relationship between adverse experiences and brain development, where adverse experiences during early adolescence are related to brain connectivity. These findings underscore the importance of studying adverse experiences beyond early childhood to understand lifespan developmental outcomes.
