Examining the reciprocal associations of muscularity bias internalization with muscularity-oriented disordered eating, muscle dysmorphia symptoms, and eating-related psychosocial impairment in Chinese adults.

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.

Multiple forms of discrimination and obsessive-compulsive disorder: a prospective cohort study.

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.

A latent class analysis of negative emotional eating in bariatric surgery candidates.

The Behavioral Susceptibility Theory posits that food approach/avoidance traits are key genetic contributors to obesity and disordered eating. The genetic tendency to approach/avoid food may manifest with emotional eating (i.e.

Validation of the muscularity bias internalization scale in Chinese transgender and gender-diverse adults.

Muscularity bias internalization (MBI) refers to one's beliefs in negative muscularity-based stereotypes and negative self-evaluations due to muscularity. 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.

Genetic Associations Between Specific Sleep-Related Phenotypes and Idiopathic Sudden Sensorineural Hearing Loss: A Mendelian Randomization Analysis.

Purpose: The relationship between idiopathic sleep-related phenotypes (SRPs) and sudden sensorineural hearing loss (ISSNHL) remains unclear. 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.

Associations between media parenting practices and early adolescent consumption of R-rated movies and mature-rated video games.

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.

Prevalence and Patterns of Social Media Use in Early Adolescents.

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 activity time predicts ADHD problems in youth from late childhood to early adolescence in the ABCD study.

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.

Stabilizing Electron Transport of 2D Materials.

2D materials are promising candidates for beyond-Si electronic devices. However, their stability is a key bottleneck in their industrial applications. 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.

Exploring the self-perceived causes of eating disorders among Chinese social media users with self-reported eating disorders.

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.

Blunted neural response to real-life social reward anticipation in internet gaming disorder: An event-related potential study.

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.

Sexual orientation discrimination and eating disorder symptoms in early adolescence: a prospective cohort study.

Background: Sexual orientation discrimination increases the risks of negative health outcomes for sexual minorities. 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.

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 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.

Muscularity bias internalization moderates the associations of muscularity dissatisfaction with muscularity-oriented disordered eating and psychosocial well-being in men but not women.

Prior research demonstrates positive associations between muscularity dissatisfaction and an array of negative health outcomes, including muscularity-oriented disordered eating, eating-related psychosocial impairment, and psychological distress. 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.

Reported higher general early-life bullying victimization is uniquely associated with more eating pathology and poor psychosocial well-being in Chinese sexual minority men.

General early-life bullying victimization has been used as an early-life marker of eating and body image disturbances and poor psychosocial well-being later in life. 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).

Negative emotional eating patterns in Chinese adolescents: A replication and longitudinal extension with latent profile and transition analyses.

This study, which is a longitudinal extension of previous cross-sectional studies in Chinese and American college students and general adults (Dixit, He, Whited, Ellis, & Zickgraf, 2023; He, Chen, Wu, Niu, & Fan, 2020; Xu et al., 2024), used latent profile and latent transition analyses to investigate negative emotional eating patterns and the stability of these patterns in 1462 Chinese adolescents (41% boys, aged 11-17 years) at baseline and 18 months later. We also explored baseline demographic predictors of negative emotional eating patterns and the associations between these patterns and outcome variables measured 18 months later.
