Eating disorders and social media use among college students in Japan and China: a brief cross-sectional survey.

In recent years, new forms of media-social networking services (SNS)-such as Facebook and Sina Weibo have spread rapidly. Greater SNS use has been associated with greater body dissatisfaction, which in turn, is related to greater eating disorder (ED) symptom severity. In this study, we (1) investigated the relationships between ED tendencies, SNS use intensity, and body esteem and (2) examined the mediating role of body esteem in the relationship between SNS use intensity and ED tendencies among Japanese and Chinese students. A total of 564 Japanese and Chinese college students aged 18-22 years were surveyed on their age and BMI, including self-filling questions from the Japanese and Chinese versions of the Eating Attitudes Test (EAT-26), SNS Intensity Scale, Body Esteem Scale for Adolescents and Adults (BESAA), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) scale. The proportion of students with a score of ≥ 20 on the EAT-26 was 15.8% (Japanese, 14.7%; Chinese, 17.0%). The number of participants with scores ≥ 20 on the EAT-26 was significantly higher than ever before, both in Japan and China. Chinese students reported greater body esteem than Japanese students, as well as a stronger association of SNS use intensity with body esteem. Among Japanese students, EAT-26 scores were unrelated to SNS Intensity Scale scores but had a weak negative correlation with BESAA scores; therefore, body esteem did not mediate the relationship between SNS use intensity and ED tendencies. Among Chinese students, scores on the SNS Intensity Scale and BESAA had a weak correlation with EAT-26 scores, and SNS use intensity reduced ED tendencies through greater body esteem. It is important to consider the way users engage with SNS, in addition to the SNS use intensity. Improving body esteem may reduce the risk of ED. Furthermore, it is necessary to include men in the discussion on ED in the future.

Media Internalized Pressure and Restrained Eating Behavior in College Students: The Multiple Mediating Effects of Body Esteem and Social Physique Anxiety.

Restrained eating behavior has become the norm in college students' lives, and considering the harm it causes to college students, it is necessary to explore the factors associated with it. The aim of this study was to explore the association between media internalized pressure, body esteem, social physique anxiety, and restrained eating behavior. The participants in this study were 1,032 Chinese college students (439 males and 593 females) and had a mean age of 20.22 years (SD = 1.277). They completed the Sociocultural Attitudes Toward Appearance Questionnaire-3, Body Esteem Scale (BES), Social Physique Anxiety Scale (SPAS), and Dutch Eating Behavior Questionnaire (DEBQ). The results showed that media internalized pressure was significantly and positively associated with college students' restrained eating behavior, that body esteem and social physique anxiety played a mediating role between media internalized pressure and restrained eating behavior, respectively, and that body esteem and social physique anxiety can also play a chained mediating role. This study reveals the relationship between media internalized pressure and restrained eating behavior, and the important role played by body esteem and social physique anxiety. Future interventions targeting restrained eating should focus on the aspects of body esteem and social physique anxiety.
