Methods: The sample consisted of 8006 early adolescents (47.

Transgender Identity and Attention Deficit Hyperactivity Disorder Symptoms: Findings From the Adolescent Brain Cognitive Development Study.

Purpose: The purpose of this study was to examine associations between identifying as transgender and attention deficit hyperactivity disorder (ADHD) symptoms in US early adolescents.

Methods: We analyzed cross-sectional data from the Adolescent Brain Cognitive Development Study (Year 3, 2019-2021) to estimate associations between gender identity and ADHD symptoms using the Child Behavior Checklist Diagnostic and Statistical Manual of Mental Disorders-oriented attention problem scale scores, adjusting for age, sex, ethnicity, parent education, household income, and study site. Additional models adjusted for stress problems and depression symptoms.

Associations between mesolimbic connectivity, and alcohol use from adolescence to adulthood.

Dopaminergic projections from the ventral tegmental area (VTA) to limbic regions play a key role in the initiation and maintenance of substance use; however, the relationship between mesolimbic resting-state functional connectivity (RSFC) and alcohol use during development remains unclear. We examined the associations between alcohol use and VTA RSFC to subcortical structures in 796 participants (12-21 years old at baseline, 51 % female) across 9 waves of longitudinal data from the National Consortium on Alcohol and Neurodevelopment in Adolescence. Linear mixed effects models included interactions between age, sex, and alcohol use, and best fitting models were selected using log-likelihood ratio tests.

Association between gender diversity and substance use experimentation in early adolescents.

Background: Gender diversity, encompassing gender identity beyond traditional binary frameworks, has been associated with substance use during adolescence. However, there is a paucity of studies that consider different dimensions of gender diversity. This study investigates associations between multiple dimensions of gender diversity and substance experimentation in early adolescents.

Associations Between Gender Diversity and Eating Disorder Symptoms in Early Adolescence.

Objective: To assess associations between multiple dimensions of gender diversity with eating disorder symptoms in a national cohort of U.S. early adolescents.

Associations of adverse childhood experiences with blood pressure among early adolescents in the United States.

The associations of adverse childhood experiences (ACEs) with blood pressure in adulthood are inconclusive. Similarly, the association between ACEs and blood pressure earlier in the life course is understudied. This study aims to assess the associations of ACEs with blood pressure among early adolescents.

Discrimination and manic symptoms in early adolescence: A prospective cohort study.

Purpose: This study aims to investigate the prospective associations between four types of perceived discrimination (country of origin, race and ethnicity, sexual orientation, and weight) and the development of manic symptoms in a diverse, nationwide sample of adolescents aged 9-14 years in the U.S.

Methods: We analyzed prospective cohort data from the Adolescent Brain Cognitive Development Study (N = 7466; ages 9-14 years at Year 1 or 2 in 2017-2020; 48.

Prospective associations between Sleep, Sensation-Seeking and Mature Screen Usage in Early Adolescents: Findings from the Adolescent Brain Cognitive Development (ABCD) Study.

Study Objectives: Early exposure to mature content is linked to high-risk behaviors. This study aims to prospectively investigate how sleep and sensation-seeking behaviors influence the consumption of mature video games and R-rated movies in early adolescents. A secondary analysis examines the bidirectional relationships between sleep patterns and mature screen usage.

A longitudinal study of the relationship between alcohol-related blackouts and attenuated structural brain development.

Purpose: Alcohol-related blackouts (ARBs) are common in adolescents and emerging adults. ARBs may also be indicative of persistent, alcohol-related neurocognitive changes. This study explored ARBs as a predictor of altered structural brain development and associated cognitive correlates.

Video gaming and sleep in adults: A systematic review.

Video games (VGs) are one of the most common forms of entertainment and their diffusion is constantly increasing. Although largely studied in the framework of their relationship with mental and physical health, the relationship of VGs with sleep are not yet fully understood. This review provides a systematic assessment of the studies that investigated the relationships between video gaming and sleep in adults.

From individual motivation to substance use initiation: A longitudinal cohort study assessing the associations between reward sensitivity and subsequent risk of substance use initiation among US adolescents.

Background: Substance use in youth remains a pressing problem in the United States. Existing studies have shown the importance of neuropathways responsible for affective response and reward motivation in adolescents' substance use initiation and maintenance. However, limited observational studies have explored the relationship between aspects of behavioral motivation traits and the likelihood of substance use initiation in adolescents.

Screen time, problematic screen use, and eating disorder symptoms among early adolescents: findings from the Adolescent Brain Cognitive Development (ABCD) Study.

Purpose: Emerging research evidence suggests positive relationships between higher screen time and eating disorders. However, few studies have examined the prospective associations between screen use and eating disorder symptoms in early adolescents and how problematic screen use may contribute to symptom development.

Methods: We analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,246, 2016-2020, ages 9-14).

Efficacy and safety of TOMAC for treatment of medication-naïve and medication-refractory restless legs syndrome: A randomized clinical trial and meta-analysis.
