Background: Studies have demonstrated that medical students' anti-fat prejudice increases over the course of training, although the mechanisms through which these prejudicial attitudes are heightened are not well understood. The present study aims to empirically examine a theoretical model that posits that the observation of weight stigma in the medical training context drives anti-fat dislike via its effects on trainees' body image and subsequent activation of weight-based stereotypes (i.e., controllability beliefs).

Methods: Data were collected from the Medical Student Cognitive Habits and Change Evaluation Study (CHANGES), a national longitudinal study conducted between 2010 and 2017. Medical students from 49 allopathic U.S. medical schools were surveyed at year 4 of medical school (MS4; N = 3,976), year 2 of residency (PGY2; N = 3,579), and year 3 of residency (PGY3; N = 3,057). A serial parallel mediation analysis using structural equation modeling was used to evaluate our model.

Results: Our model was largely supported; observations of weight stigma during medical school were directly and indirectly associated with greater anti-fat dislike at PGY3 via fear of weight gain and controllability beliefs about weight.

Conclusions: Anti-fat prejudice reduction interventions in the medical training environment should (1) emphasize the importance of, and increase adherence to, positive attitudinal role modeling among faculty and residents, (2) promote body self-acceptance among trainees, and (3) provide education around the complex interplay of genetic and environmental contributors to combat blame-based stereotypes surrounding weight.

Background: This study aims to investigate how occupational stigma consciousness impacts employee negligence behavior with the mediating role of ego depletion and moderating role of emotional intelligence in the healthcare sector of China. Drawing on self-regulation theory and emotional intelligence literature, we propose that while occupational stigma depletes employees' psychological resources, emotional intelligence serves as a personal capability that may buffer the adverse emotional and cognitive effects of stigma, making its moderating role theoretically meaningful in this context.

Methods: Hypotheses were tested using data collected from 247 healthcare employees in China through a three-wave time-lag design. Specifically, occupational stigma consciousness was measured at Time 1, ego depletion at Time 2 (four weeks later), and employee negligence behavior at Time 3 (four weeks after Time 2).

Results: The results direct occupational stigma consciousness increases employee negligence behavior. The author also found ego depletion mediates the relationship between occupational stigma consciousness and employee negligence behavior. However, the buffering role of emotional intelligence was not established.

Background: Adolescence is a critical period for physical and mental health development. Chinese adolescents face multiple challenges such as academic pressure, with considerable mental health risks. Positive health behaviors are closely associated with physical and mental health, but their complex interaction network remains unelucidated.

Methods: Cross-sectional survey was conducted on 436 middle school students with positive health behavior scale and SCL-90. The network of 15 nodes (10 mental health symptoms and 5 positive health behaviors) was constructed by network analysis. The stability of the network was tested by correlation stability analysis. The core nodes were determined by centrality index. The cross-system association strength was analyzed by bridge effect expectation (BEI).

Results: The network showed robust stability (CS coefficient = 0.75). Anxiety was the core node in mental health symptoms, positively correlated with somatization (r = 0.26) and hostility (r = 0.22). Circadian self-regulation was positively correlated with psychopathology (r = 0.52). Physical activity served as a cross-system bridge, negatively correlated with depression (r = -0.08). No significant gender differences in network characteristics were observed.

Conclusion: Adolescent positive health behaviors and mental health form a complex association network. Anxiety is a core driver of psychological symptoms, and physical activity is a key cross-system bridge for improving mental health. The findings provide a theoretical basis for developing targeted intervention strategies focusing on physical activity.
