Emerging empirical evidence supports muscularity bias internalization as a close correlate of muscularity-oriented disordered eating, muscle dysmorphia symptoms, and eating-related psychosocial impairment. However, there is a lack of research investigating the longitudinal links of muscularity bias internalization with these related variables. Drawing on longitudinal research evidence from weight bias internalization supporting reciprocal associations with biopsychosocial outcomes, the present study examined the reciprocal associations of muscularity bias internalization with muscularity-oriented disordered eating, muscle dysmorphia symptoms, and eating-related psychosocial impairment.

Purpose: This study aimed to examine prospective associations between screen time and manic symptoms in early adolescents, and the extent to which problematic screen use (characterized by addiction, conflict, relapse, and withdrawal) mediates the association.
Methods: We analyzed prospective cohort data from the Adolescent Brain Cognitive Development Study (N = 9,243; ages 10-11 years in Year 1 in 2017-2019; 48.8% female; 44.

Background: Discrimination increases the risk for adverse mental health in minority populations, with studies showing elevated rates of obsessive-compulsive disorder (OCD) in Black adults facing racial discrimination. Yet, there is a lack of longitudinal research on the different forms of discrimination in relation to OCD risk in early adolescence. The objective of this study was to examine the prospective associations between multiple forms of discrimination and OCD in a national sample of U.

Empirical research shows that MBI significantly correlates with muscularity-oriented eating and body image disturbances. The Muscularity Bias Internalization Scale (MBIS) measures MBI and has been validated in general adult populations.

This study was designed to investigate the link between SRPs and ISSNHL from a genetic perspective through Mendelian randomization (MR) analysis.
Methods: ISSNHL trials were downloaded from Finngen database.
Objective: To assess whether specific parent media practices are associated with the consumption of R-rated (restricted) movies and mature-rated video game use in early adolescents.
Methods: Data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,054, 12-13 years, Year 3, 2019-2021) were analyzed. Ordinal logistic regression models were used to assess associations among media parenting practices and R-rated movies or mature-rated video game use, adjusting for potential confounders.
Objective: To describe patterns of social media use, including underage use (under 13 years) and sex differences, in a diverse, national sample of early adolescents in the US.
Methods: We analyzed the social media use data in the Adolescent Brain Cognitive Development Study (2019-2021, Year 3), which includes a national sample of early adolescents in the US. Specifically, using Chi-square and t-tests, we compared social media use patterns across demographic characteristics stratified by age and sex.

Online social interactions increase into adolescence. Although cross-sectional studies have positively associated online social activity (OSA) time and attention-deficit/hyperactivity disorder (ADHD) problems, the directionality remains unclear. Therefore, we examined longitudinal associations between OSA time and ADHD problems using data from the Adolescent Brain Cognitive Development (ABCD) study.

The instability of 2D materials is mainly attributed to their intrinsic susceptibility to O and HO-particularly to reactive oxygen species (ROS), which have strong oxidizing properties.

Background: Even though robust evidence suggests the high prevalence of eating disorders (EDs) in China, EDs in China are characterized by low diagnosis rates, delayed treatment-seeking, and ineffective treatments. Given that listening to patients' perspectives and lived experiences is crucial to improving our understanding of EDs in the Chinese context, an investigation of the perceived causes of EDs in Chinese individuals with EDs represents a key step in improving the prevention and treatment of EDs in China.
Aims: To explore the perceived causes of EDs based on data from a sample of Chinese social media users with self-reported EDs, with a particular focus on the Zhihu platform.
Recent research indicates that individuals with Internet gaming disorder (IGD) exhibit impaired social reward processing, evidenced by reduced neural sensitivity to real-life social reward. The aim of the present study is to further investigate the impaired processing of social reward anticipation and reward consumption in individuals with IGD, and explore the relationship between these two components. Using a social incentive delay task with game-related and real-life versions, combined with event-related potential (ERP) technology, we examined 25 individuals with IGD and 25 matched healthy game players.

Previous studies have found increased rates of eating disorder symptoms in sexual minority individuals, which is attributable to minority stress and discrimination that they experience. Emerging research suggests relationships between sexual orientation discrimination and eating disorder symptoms.

However, muscularity dissatisfaction differs by gender and is not always linked to these outcomes, indicating the existence of moderators of these associations. We proposed and examined muscularity bias internalization (MBI) as a moderator of these associations.

We expand existing research in this area to Chinese sexual minority (SM) men, a vulnerable and under-researched subgroup, by considering associations of general early-life bullying victimization with current eating and body image disturbances and poor psychosocial well-being. We assessed demographics, general early-life bullying victimization, past appearance teasing, current thinness- and muscularity-oriented eating and body image disturbances, and current psychosocial well-being in Chinese SM men (N = 433).
