“…Papers from mainland China, Singapore, and Iran revealed that the prevalence of EDs in those regions appears to be comparable to-or perhaps even higher than-that observed in Western countries. Specifically, Yao et al (2021) described the prevalence and sociodemographic factors associated with screen-detected disordered eating and related traits in a population-based sample of women in mainland China. They found that approximately 7% screened positive for an ED, and that urban residence and higher levels of education were associated with greater risk.…”

Objective: It is our pleasure to introduce a special issue of the International Journal of Eating Disorders on eating disorders (EDs) in Asia. Method: We received such a robust response to the special edition that we were able to fill two issues. Contributions focused on seven main themes: (1) prevalence, (2) time trends, (3) healthcare systems, (4) treatment, (5) risk factors, (6) assessment, and (7) orthorexia. Results: New prevalence and time trend data from China, Iran, Singapore, Japan, and Taiwan suggest that EDs are increasingly common in Asia but are not always detected in healthcare settings. Only a minority of individuals with EDs in Singapore receive treatment, and psychosocial treatment and prevention interventions that are evidence-based in the West may require cultural adaptation before they can be fully implemented in Japan, Singapore, China, and South Korea. Psychological risk factors for EDs are more similar than different in Iran, India, Japan, and China, but biological risk factors are understudied across the continent. Psychometrically sound assessment tools are available in many Asian languages. Discussion: We hope this special issue provides a catalyst and blueprint for global collaboration to relieve the burden of suffering of EDs in Asia and beyond.

“…The lifetime prevalence rate of EDs is 2–8% in the US ( 3 ), and 20–20.6% of the college students were at risk of an eating disorder in some South-East Asian countries ( 4 ). Recent studies show that the prevalence of EDs in China is increasing ( 5 ). Tong et al, found a comparable prevalence of EDs in female university students (3.53% for binge-eating disorder, 2.98% for bulimia nervosa, and 1.05% for anorexia nervosa) to that of their western counterparts ( 6 , 7 ).…”

Background: Sleep problems and eating disorders (EDs) are both serious public health concerns often seen in young adults. Yet, the underlying mechanisms for such associations are largely unknown. This study aims to examine potential serial multiple mediation effects of problematic smartphone use (PSU) and psychological distress (i.e., depressive and anxiety symptoms) in the relationship between sleep quality and disordered eating behaviors/attitudes (DEBs).Methods: A total of 4,325 students from two Tibet universities in China (2,657 females and 1,668 males) completed an online survey that included the following measurements: Eating Attitude Test-26 for disordered eating behaviors/attitudes, the Chinese Version of Pittsburgh Sleep Quality Index (CPSQI), Smartphone Addiction Scale—Short Version (SAS-SV) for problematic smartphone use, Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) for psychological distress.Results: While the direct path linking sleep quality and DEBs was not found to be significant (Standardized β = 0.006, 95% CI = −0.0667~0.0970), both PSU (Standardized β = 0.016, 95% CI = 0.0256~0.0591) and anxiety symptoms (Standardized β = 0.014, 95% CI = 0.0203~0.0526) may mediate a link between sleep quality and DEBs; serial multiple mediation analysis revealed that a serial indirect pathway of “sleep quality -> PSU -> anxiety symptoms -> DEBs” existed(Standardized β = 0.001, 95% CI = 0.0002~0.0012). Similarly, while the direct path linking sleep quality and DEBs was not found to be significant (Standardized β = 0.006, 95% CI = −0.0667~0.0970), both PSU (Standardized β = 0.020, 95% CI = 0.0337~0.0692) and depressive symptoms (Standardized β = 0.015, 95% CI = 0.0139~0.0652) may mediate a link between sleep quality and DEBs; serial multiple mediation analysis revealed that a serial indirect pathway of “sleep quality -> PSU -> depressive symptoms -> DEBs” existed (Standardized β = 0.001, 95% CI = 0.0006~0.0038).Conclusions: Psychological and behavioral factors may comprehensively work together, leading to flow-on effects from sleep problems to disordered eating behaviors among university students. Appropriate interventions that target problematic smartphone use could thus potentially reduce anxiety and depression levels, which in turn will provide a buffer against the negative impact of poor sleep quality on eating disorder symptoms.

“…These symptoms prevent patients from understanding the seriousness of the disease, as a result, they keep in a constant state of the illness, which leads to serious distress and burden on their families and society. In particular, the incidence of the disease is continuing to rise in China and is already comparable to the worldwide incidence [3]. Growing interest has focused on the pathogenesis and treatment of AN.…”

Purpose: The serotonin system and parenting styles have been reported to be involved in the pathogenesis of anorexia nervosa (AN). The study was aimed to explore the effect of the methylation of the promoter region of serotonin transporter gene (SLC6A4), also called 5-HTTLPR, parenting styles as well as their interaction on AN.Methods: 91 AN patients (ANs) and 87 healthy controls (HCs) were recruited, from whom 41 ANs and 40 HCs completed the environmental assessment. 5-HTTLPR methylation levels, clinical symptoms and environmental factors were assessed at baseline for all participants. 5-HTTLPR methylation was measured by MassArray methods and clinical symptoms were mainly evaluated by the EDE-Q6.0 scale. Environmental assessment is the parenting attitudes and behaviors used by the EMBU scale.Results: ANs had higher methylation at CpG 11, CpG 24.25, CpG 31.32 and CpG_mean than HCs (P=0.039, 0.042, 0.018, 0.001). Furthermore, it was the binge/purging subtype that revealed significant hypermethylation at CpG 24.25 and CpG_mean (P=0.027, 0.031). Both CpG11 methylation level and the parenting styles of refusal denial, overprotection for father were both positively correlated the EDEQ-6.0 scores in ANs (P=0.047, 0.018). Besides, their interaction analysis found, it was the overprotection, not the refusal denial for father that significantly associated with EDEQ-6.0 scores in ANs (P=0.030).Conclusions: Our study provided preliminary evidence that 5-HTTLPR DNA methylation at CpG11 and parenting styles of refusal denial, overprotection for father played vital roles in AN pathogenesis. Their interaction analysis indicated it was father’s overprotection that significantly associated with the clinical symptoms in ANs.
