However, the potential mediating effect of impulsivity on the relationship between BV and murderous behaviors in early adolescents remains underexplored.

Methods: A total of 5724 adolescents, with a mean age of 13.

Sex-specific association of peripheral blood cell indices and inflammatory markers with depressive symptoms in early adolescence.

Background: Previous studies have reported the correlation of dysregulated blood cell indices and peripheral inflammatory markers with depression in adults but limited studies have examined this correlation in early adolescents.

Methods: This study used data from the Chinese Early Adolescents Cohort Study, which was conducted in Anhui, China. Students' depression symptoms were repeatedly measured using the Chinese version of the Center for Epidemiological Studies Depression Scale for Children.

Inconsistency in psychological resilience and social support with mental health in early adolescents: A multilevel response surface analysis approach.

Background: Given the high prevalence of adolescent mental health problems, promoting understanding and implementation of protective factors is crucial for prevention and intervention efforts addressing adolescent mental health problems. This study aims to investigate whether consistency and inconsistency in protective factors are associated with adolescent mental health problems and to inform adolescent mental health interventions that target the unique needs of adolescents and promote adolescent mental health.

Methods: We used multistage cluster sampling to conduct psychological resilience, social support, and mental health questionnaires from April to June 2023 among 10,653 Chinese adolescents (52.

Multi-level factors associated with psychological resilience in the face of adverse childhood experiences among Chinese early adolescents.

Background: Adverse childhood experiences (ACEs) are pervasive and exert enduring negative effects on health throughout one's life. A better understanding of resilience among adolescents with ACEs exposure is crucial to enhance their mental health; however, comprehensive and multifaceted analyses of its associated factors are limited.

Objective: This study aimed to investigate multi-level correlates of psychological resilience in Chinese early adolescents exposed to ACEs.

Longitudinal and Reciprocal Effects in the Association Between School Bullying and Homicidal Ideation During Early Adolescence.

Several cross-sectional studies indicated a positive association between school bullying and homicidal ideation during early adolescence. However, few longitudinal studies investigated this association. This study examined whether a bi-directional relationship exists within the longitudinal association between bullying victimization or bullying perpetration and homicidal ideation among early adolescents using a Random Intercept Cross-Lagged Panel Model.

Bidirectional relationship between borderline personality features and depressive symptoms in early adolescence: A school-based cohort study.

Depressive symptoms is a public health concern worldwide, and adolescents may experience more depressive symptoms. Although the relationship between borderline personality features (BPFs) disorder and depressive symptoms has been established, it is unclear whether the longitudinal relationship between them is unidirectional or bidirectional and whether these symptoms are different between boys and girls. In this study, Chinese adolescents (1608 total and separately 972 for boys and 636 girls) were enrolled between September 2019 and September 2021, and we analyzed the data using a cross-lagged model.

Vitamin D and depressive symptoms in an early adolescent cohort.

Background: To explore the cross-sectional and longitudinal association between vitamin D and depressive symptoms across early adolescence.

Methods: This longitudinal study included 1607 early adolescents [mean (s.d.

Association Between Child Maltreatment and Aggression in Chinese Early Adolescents: The Mediating Role of Irritability.

Child maltreatment (CM) is a major global public health issue, and a strong association exists between CM and aggression. However, the underlying mechanism of this association has not been understood to date. The objective of this study was to explore the mediating role of irritability in the association between CM and aggression in Chinese early adolescents.

Longitudinal trajectories of sleep quality in correlation with maltreatment in early childhood: A cohort of Chinese early adolescents.

Background: Child maltreatment may lead to sleep disturbance during the critical period of child development. Our study examined the effect of maltreatment in early childhood on trajectories of sleep quality among early adolescents.

Methods: The study included 1611 participants (mean ± standard deviation age at baseline: 12.

Longitudinal correlates of bullying victimization among Chinese early adolescents: A cross-lagged panel network analysis.

Background: Bullying victimization is a major public health issue often faced by adolescents. This highlights the need to identify the relevant risk factors to inform intervention. Based on the ecological systems theory and applied cross-lagged panel network analysis, this study explored the longitudinal correlates of bullying victimization among Chinese early adolescents.

Childhood maltreatment and homicidal ideation among Chinese early adolescents: The serial mediating role of borderline personality features and aggression.

A large body of evidence linked childhood maltreatment (CM) to juvenile violence and delinquent behavior. However, little is known about the association between CM and homicidal ideation in early adolescents. This study aimed to examine that relationship and to explore the serial mediating role of borderline personality features (BPF) and aggression in that relationship in a large sample of early adolescents.

Enhancing de novo ceramide synthesis induced by bisphenol A exposure aggravates metabolic derangement during obesity.

Objective: Exposure to bisphenol A (BPA) has been shown to increase the prevalence of obesity and its related insulin resistance (IR). Ceramide is a sphingolipid known to facilitate the production of proinflammatory cytokines and subsequently exacerbate inflammation and IR during the progression of obesity. Here, we investigated the effects of BPA exposure on ceramide de novo synthesis and whether increased ceramides aggravate adipose tissue (AT) inflammation and obesity-related IR.

Involvement in bullying and sleep disorders in Chinese early adolescents.

Background: School bullying may cause sleep disorders in early adolescents. Here, we determined the relationship between school bullying (considering all the features of bullying involvement) and sleep disorders, which are the common problems in Chinese early adolescents.

Materials And Methods: We conducted a questionnaire survey among 5,724 middle school students from Xuancheng, Hefei, and Huaibei cities in Anhui province, China.

Bidirectional association between sleep quality or duration and aggressive behaviour in early adolescents: A cross-lagged longitudinal study.

Background: Several cross-sectional studies have suggested a strongly positive link between sleep and aggressive behaviour; however, longitudinal studies reporting the relationship between sleep and aggressive behaviour are lacking. This study aimed to examine whether a bidirectional relationship exists between sleep quality or duration and aggressive behaviour in early adolescents.

Methods: A total of 1579 early adolescents (60.

Gestational bisphenol A exposure advances puberty onset in female offspring: Critical time window identification.

Increasing evidence shows that the early onset of puberty in female offspring may be caused by maternal prenatal exposure to bisphenol A (BPA) during pregnancy; however, the critical time window of maternal prenatal BPA exposure remains unknown. Here, we identify the critical time window of gestational BPA exposure that induces early onset of puberty in female offspring. Pregnant CD-1 mice were gavaged with BPA (8 mg/kg) daily during the early gestational stage (GD1-GD6), middle gestational stage (GD7-GD12) or late gestational stage (GD13-GD18).
