Bulimia nervosa selectively reshapes the structure and intrinsic function of anterior insula subregions associated with cognition-emotion integration. J Affect Disord 2024; 362:529-535. [PMID: 39013519 DOI: 10.1016/j.jad.2024.07.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 06/17/2024] [Accepted: 07/12/2024] [Indexed: 07/18/2024]
Abstract
BACKGROUND Existing evidence suggests that anterior insula plays a crucial role in cognitive control and emotional regulation and is implicated in the onset and maintenance of bulimia nervosa (BN). However, it remains unclear how structural and functional abnormalities in specific subregions of anterior insula contribute to BN. METHODS In this study, we analyzed structural MRI and resting-state functional MRI data from 54 BN patients and 56 healthy controls (HCs). We conducted voxel-based morphometry, amplitude of low frequency fluctuation (conventional band: 0.01-0.08 Hz, slow-5: 0.01-0.027 Hz) and seed-based whole-brain functional connectivity (FC) analysis of the anterior insula subregions for both groups. Additionally, we investigated the correlation between neuroimaging findings and clinical characteristics in the BN group. RESULTS Our findings revealed that BN patients exhibited reduced gray matter volume in the right dorsal anterior insula (dAI) and bilateral ventral anterior insula (vAI) and demonstrated decreased ALFF in slow-5 band of bilateral dAI. The BN group also showed increased FC between bilateral dAI and precuneus or right superior frontal gyri which significantly correlated with the severity of BN or its key symptom. In addition, the decreased FC between bilateral vAI and anterior cingulate and paracingulate gyri and/or median cingulate and paracingulate gyri were both significantly correlated with the severity and its restrained eating behavior. CONCLUSIONS Our findings further indicate that the functional separation of anterior insula subregions may underlie the pathophysiology of BN. Notably, the vAI associated with emotional processing may serve as a promising neuroimaging biomarker which could inform therapeutic strategy.

[PMID: 38652332 PMCID: PMC11039549 DOI: 10.1007/s40519-024-01656-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Accepted: 04/02/2024] [Indexed: 04/25/2024] Open
Abstract
PURPOSE The SCOFF questionnaire was designed as a simple, memorable screening tool to raise suspicion that a person might have an eating disorder. It is over 20 years since the creation of the SCOFF, during which time it has been widely used. Considering this, we wish to review the use of the SCOFF in peer-reviewed scientific journals, and to assess whether it is being used appropriately in the manner in which it was originally devised and tested. METHODS The Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA) guidelines were followed, and all search strategies and methods were determined before the onset of the study. PubMed and Wiley Online Library were searched using the terms SCOFF and eating. Two reviewers were involved in the reviewing process. Criteria for appropriate use of the SCOFF were formalised with the tool's original authors. RESULTS 180 articles were included in the final review. 48 articles had used the SCOFF appropriately, 117 articles inappropriately and 15 articles had been mixed in the appropriateness of their use. CONCLUSION This systematic review highlights the inappropriate use of the SCOFF in diverse languages and settings. When used correctly the SCOFF has made a significant contribution to the understanding of eating disorders and its simplicity has been applauded and led to widespread use. However in over two-thirds of studies, the use of the SCOFF was inappropriate and the paper highlights how and in what way it was misused, Guidelines for the appropriate use of the SCOFF are stated. Future validation and avenues of research are suggested. LEVEL OF EVIDENCE Level I.

Int J Eat Disord 2023; 56:1842-1853. [PMID: 37337937 DOI: 10.1002/eat.24012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 05/07/2023] [Accepted: 06/05/2023] [Indexed: 06/21/2023]
Abstract
OBJECTIVE Previous studies have revealed associations between disordered eating symptoms, big-five personality traits, and psychological distress. However, limited research has explored these relationships as a network, including their interconnections, and even less has done so in non-Western populations. We employed network analysis to investigate the co-occurrence of disordered eating symptoms, big-five personality traits, and psychological distress in Chinese adults. METHOD A sample of 500 Chinese adults (256 men) completed measures assessing big-five personality traits, psychological distress, and disordered eating symptoms. The network of personality traits, psychological distress, and disordered eating symptoms was estimated, including its central and bridge nodes. RESULTS The central nodes in the network were the facets of openness (like adventure), extraversion (like going to social and recreational parties), and disordered eating symptoms (dissatisfaction with body weight or shape). Moreover, certain facets of neuroticism (always worrying something bad will happen), psychological distress (feeling worthless), and an inverse facet of extraversion (bored by parties with lots of people) were identified as essential bridge nodes in maintaining the structure of the network. CONCLUSION Our findings suggest that personality traits (e.g., openness and extraversion) and body dissatisfaction are important in maintaining the network in a community sample of Chinese adults. While future replication is needed, findings from this study suggest that individuals with negative self-thinking, predisposed neuroticism, and extraversion may be at risk of developing disordered eating symptoms. PUBLIC SIGNIFICANCE The present study contributes to existing knowledge by employing a network perspective to examine the associations between disordered eating symptoms, big-five personality traits, and psychological distress in a Chinese adult community sample. The identified facets of neuroticism and extraversion and symptoms of psychological distress may be worthy of targeting in the prevention and treatment of disordered eating in the Chinese context.

Abstract
OBJECTIVE We tested an integrated model of three prominent theories of disordered eating (tripartite influence theory, objectification theory, and social comparison theory) in a sample of older Chinese men and women. METHOD Chinese older men (n = 270) and women (n = 160) completed questionnaires assessing the tripartite influence, objectification, and social comparison theories and thinness- and muscularity-oriented disordered eating. Two structural equation models were tested in Chinese older men and women. RESULTS The integrated model showed good model fit and described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older men and women. Higher appearance pressures were uniquely related to higher muscularity-oriented disordered eating in men. Across both gender groups, higher thinness internalization was uniquely related to higher thinness- and muscularity-oriented disordered eating, and in women only, higher muscularity internalization was uniquely related to lower thinness-oriented disordered eating. In men, higher upward and downward body image comparisons were uniquely related to higher and lower, respectively, muscularity-oriented disordered eating. In women, higher upward body image comparisons were only uniquely related to higher muscularity-oriented disordered eating while higher downward body image comparisons were uniquely related to both outcomes. Higher body shame was uniquely related to higher thinness-oriented disordered eating across both groups and in men alone, higher body shame was also uniquely related to higher muscularity-oriented disordered eating. DISCUSSION Findings, which tested the integration of tripartite influence, objectification, and social comparison theories, inform the prevention and treatment of disordered eating in Chinese older populations. PUBLIC SIGNIFICANCE The present study is the first to describe theories of disordered eating (tripartite influence, objectification, and social comparison) in Chinese older adults. Findings suggested good model fit and the integrated models described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older women and men. Findings extend existing theories of disordered eating and, pending further study, may inform theory-driven prevention and treatment approaches in Chinese older adults.

Abstract
BACKGROUND As women continue to be more at risk from eating disorders, gender has often been a focus of concern in transcultural research. Yet feminist, qualitative studies which prioritize the voices of women/girls remain rare within transcultural work suggesting the need for greater interaction between these fields. This article seeks to contribute to the exploration of the applicability of feminist paradigmslargely developed in the West-to experiences of EDs in non-western contexts. METHODS This article draws on semi-structured interviews with 12 women from urban China with self-reported experience of Bulimia Nervosa (BN) and binge eating disorder (BED) in order to explore the complex ways in which gender may be implicated within eating/body distress from a transcultural point of view. The data is analysed through Reflexive Thematic Analysis. RESULTS The data analysis suggested two broad themes: (1) Chinese versus Western codes for judging female appearance: from surveillance to liberation (2) Discipline, appetite and control: the gendered/cultural meanings of binging and purging. In terms of the first theme, many participants had spent time in the West which was understood as a less regulated context in terms of gendered body surveillance and eating. Complicating existing assumptions about the 'Westernisation' thesis, different communication codes and peer interactions across Chinese and Western contexts played a central role in how participants experienced their bodies. In the second theme, binging and purging emerged as a way to manage a number of contradictions surrounding Chinese femininity, including respecting familial food cultures, contradictory discourses on female 'appetite', and the need to display a female body which signified cultural imperatives of self-restraint and discipline. CONCLUSIONS The data emphasises the importance of examining the culturally specific meanings of eating problems and their gendered contexts, whilst there is clearly much that echoes Western feminist work on Western samples. Although limited, the study crucially points to the importance of examining how ED subcategories other than AN can be explored from a transcultural and feminist point of view.

Abstract
Body talk has received increasing research attention in recent years, with accumulating evidence supporting the link between body talk and eating and body image disturbances. However, research on body talk in China is still relatively scarce and generally focused on fat talk, especially in women, and much remains unknown about muscle talk and positive body talk for both Chinese women and men. To promote a better understanding of body talk in the Chinese context, the present study adapted the Body Talk Scale (BTS) into Chinese Mandarin (i.e., C-BTS) and evaluated the factor structure and psychometric properties of the C-BTS in Chinese adult women and men. The English version of the BTS was translated into Chinese Mandarin with standard procedures. With 300 Chinese women (Mage = 29.48 years, SD = 7.26) and 300 men (Mage = 29.36 years, SD = 6.81), we examined the factor structure and gender invariance of the C-BTS, as well as internal consistency reliability, test-retest reliability, and construct validity, including convergent, concurrent, and incremental validity of the C-BTS. The results indicated that, consistent with the development study of the BTS, the C-BTS had three subscales (i.e., Negative Fat Talk, Negative Muscle Talk, and Positive Body Talk) and good reliability and validity. The findings demonstrate that the C-BTS can be a useful measure of body talk in both Chinese women and men.

Abstract
Background Eating disorders (EDs) and depression are common in university students, especially during the COVID-19 pandemic. The aim of this study was to elucidate characteristics of EDs and depression symptoms networks among Chinese university students in the later stage of the COVID-19 pandemic in China. Methods A total of 929 university students completed the SCOFF questionnaire measuring EDs and Patient Health Questionnaire with 9 items (PHQ-9) measuring depression in Guangzhou, China. The network model was applied to identify central symptoms, bridge symptoms, and important connections between SCOFF and PHQ-9 using R studio. The subgroup analyses of both genders in medical and non-medical students were further explored. Results In the networks of the whole sample, central symptoms included "Loss of control over eating" (EDs) and "Appetite changes" (depression). The bridge connections were between "Loss of control over eating" (EDs) and "Appetite changes" (depression), between "Deliberate vomiting" (EDs) and "Thoughts of death" (depression). "Appetite changes" (depression) and "Feeling of worthlessness" (depression) were central symptoms in both subgroups of medical and non-medical students. "Fatigue" (depression) was the central symptom in the female and medical students group. The edge between "Loss of control over eating" (EDs) and "Appetite changes" (depression) acted as a bridge in all subgroups. Conclusion Social network approaches offered promising ways of further understanding the association between EDs and depression among university students during the pandemic of COVID-19 in China. Investigations targeting central and bridge symptoms would help to develop effective treatments for both EDs and depression for this population.

Abstract
Purpose It has been reported that serotonergic systems and parenting styles are involved in the pathogenesis of anorexia nervosa (AN). The present study made attempts to examine the DNA methylation profiles in the promoter region of serotonin transporter (5-HTT) encoding gene SLC6A4, and explore the association between the methylation level and severity of symptoms, 5-HTT linked polymorphic region (5-HTTLPR) genotypes and parenting styles in untreated Chinese Han AN patients. Methods Ninety-one untreated female AN patients (ANs) and eighty-seven matched healthy controls (HCs) were analyzed for DNA methylation status at CpG islands in the promoter region of SLC6A4 using MassARRY EpiTYPER, and genotypes of 5-HTTLPR using PCR-RFLP. The severity of eating disorder (ED) symptoms was evaluated by body mass index (BMI) and Questionnaire Version of the Eating Disorders Examination (EDE-Q 6.0), and part of participants were assessed parenting styles using the short Chinese Egna Minnen av Barndoms Uppfostra (s-EMBU-C). Results ANs had greater methylation levels at CpG26.27.28, CpG 31.32, and CpG 37 than HCs (P = 0.039, 0.042, 0.018 respectively). A positive association of methylation level at CpG26.27.28 with ED symptoms detected by EDEQ-6.0 was discovered in AN group (r = 0.216, P = 0.047). Methylation level at CpG26.27.28 was showed to be or tend to be positively correlated with the parenting styles of paternal rejection (r = 0.425, P = 0.038) and paternal overprotection (r = 0.362, P = 0.062) in ANs. No significant differences were found in SLC6A4 promoter region methylation levels among 5-HTTLPR genotypes in our samples (P > 0.05) and no interaction effect between 5-HTTLPR genotypes and parenting styles on SLC6A4 promoter region methylation was observed (P > 0.05). Conclusions This study suggested that hypermethylation of SLC6A4 promoter region may be implicated in the pathological mechanisms of untreated Chinese Han female ANs, which is possibly associated with poor parenting styles. This finding may provide a direction for the epigenetic and family treatments for ANs and further investigation with larger samples is warranted.

Abstract
Hedonic hunger refers to food consumption for pleasure without biological energy deficits. The Power of Food Scale (PFS) is a well-developed self-report instrument assessing hedonic hunger. The present study aimed to translate and validate the PFS into simplified Chinese (C-PFS) and examine its psychometric properties among Chinese adults. A total of 773 participants (51.1 % men, M age = 24.98 years, SD = 6.10) were recruited in the present study from college and community populations. Consistent with the previous studies, confirmatory factor analysis showed that the C-PFS had three factors: food present, food available, and food tasted. In addition, a Cronbach's alpha of 0.92 and an ICC of 0.86 suggested that the C-PFS has good internal consistency and test-retest reliability. In terms of convergent validity, the scores of C-PFS correlated significantly with disordered eating symptomatology and loss of control over eating. Measurement invariance tests showed that the C-PFS was invariant across gender and sample source groups in the Chinese sample. In addition, a U.S. sample of 490 college students (26.6 % men, M age = 21.41 years, SD = 5.45) was used to test the measurement invariance across countries, and results suggested a partial invariance across college students from China and those from the U.S. In conclusion, the C-PFS can be a useful tool for measuring hedonic hunger among adults in China, and there may be cultural differences in the measurement of the PFS in college students across China and the U.S.

The Body Acceptance by Others Scale-2 (BAOS-2) was developed to assess overall perceived body acceptance by others. In two studies, we evaluated its structure, reliability and validity among young adults in China. In Study 1, 435 women and 322 men completed newly translated simplified Chinese versions of the BAOS-2 and Functionality Appreciation Scale (FAS), conceptually related body image questionnaires and demographic items. Exploratory factor analyses supported a 13-item unidimensional BAOS-2 structure across men and women. Internal consistency, test-retest reliability, convergent validity and discriminant validity were also supported. Study 2 (307 men, 396 women) replicated the original gender-invariant BAOS-2 structure in confirmatory factor analysis and bolstered evidence for convergent, discriminant and incremental validity. Predictive validity, examined via longitudinal analyses, indicated baseline BAOS-2 scores and/or concomitant changes in BAOS-2 scores over time were related to improvements on other positive and negative body image measures at a six-month follow-up. Supplementary analyses replicated the original unidimensional FAS factor structure and provided considerable support for its psychometrics across samples. In sum, this research supported psychometric properties of the BAOS-2 among young adults in China and underscored its potential utility in predicting changes in other body image experiences over time.

Risk factors for eating disorders among Chinese and international university students: a comparative cross-sectional study. Cent Eur J Public Health 2022; 30:241-247. [PMID: 36597986 DOI: 10.21101/cejph.a6998] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 12/08/2022] [Indexed: 01/05/2023]
Abstract
OBJECTIVE The aim of the study was to investigate the prevalence of eating disorders (EDs) and their association with socio-demographic and behavioural factors among university students. METHODS A cross-sectional study among university students (Chinese and international) in Nanjing, China. We collected the data from 877 students, of which 811 were eligible for this study. They submitted a self-administered questionnaire (Eating Disorder Examination Questionnaire 6 (EDE-Q6) related to socio-demographic, health variables and lifestyle factors. Data were assessed with the help of SPSS software. RESULTS A total of 401 Chinese and 410 international university students (49.44% vs. 50.55%) participated in this study. Binary logistic regression showed that young female adults of 18~25 years of age had more risk of developing eating disorders. Higher body mass index (BMI), such as overweight and obesity, were more influential risk factors (p < 0.001) for eating disorders. The significant risks (p < 0.001) EDs were found in students who were athletes, physically active, and involved in various extra-curricular activities. Alcohol and smoking were significant risk factors associated with eating disorders. CONCLUSION The results indicated higher risks of eating disorders followed by objective binge eating and compensatory behaviour. In this scenario, early assessment and treatment are necessary to reduce the burden of eating disorders and to promote good nutritional practices among university students.

Abstract
Given existing empirical support for the tripartite influence and social comparison models to explain variance in body dissatisfaction and disordered eating across diverse populations in the Western context, research is needed to describe these models in non-Western populations. The present study tested an integrated model inclusive of appearance pressures, thinness and muscularity internalizations, and social comparisons in relation to drive for muscularity and thinness-oriented disordered eating in heterosexual Chinese adult men (n = 510) and women (n = 473). Separated by gender, two integrated models had good fit statistics per structural equation modeling. In men and women, higher appearance pressures were uniquely related to higher drive for muscularity and thinness-oriented disordered eating. In men and women, higher thinness and muscularity internalizations were uniquely related to higher thinness-oriented disordered eating and drive for muscularity, respectively. In men and women, higher upward body image comparisons were uniquely related to higher drive for muscularity, and in men only, higher downward body image comparisons were uniquely related to higher thinness-oriented disordered eating. The present findings, which extend theories of eating pathology, may aid in improving treatment efforts for body dissatisfaction and disordered eating in heterosexual Chinese adult men and women.

Abstract
PURPOSE OF REVIEW We systematically reviewed the recent literature on the epidemiology of eating disorders in Latin America. RECENT FINDINGS Most screened articles only investigated risk for eating disorders or disordered eating behaviors. Four studies reported prevalence for eating disorders. One study reported age-standardized prevalence ranging from 0.04% [95% confidence interval, CI (0.03, 0.06)] to 0.09% [95% CI (0.07, 0.13)] for anorexia nervosa and from 0.13% [95% CI (0.08, 0.17)] to 0.27% [95% CI (0.18, 0.37)] for bulimia nervosa. Three additional studies conducted in Brazil identified a general eating disorder point-prevalence of 0.40% in children aged 6--14 years and a point-prevalence of 0.7 % [95% CI (0.34, 1.55)] for bulimia nervosa, 1.4% [95% CI (0.81, 2.43)] for binge-eating disorder and 6.2% [95% CI (3.10, 5.27)] for recurrent binge eating. SUMMARY Since 2020, only few studies were published on the epidemiology of full-threshold eating disorders in Latin America. Prevalence was in a comparable range to previous findings. No studies regarding new DSM-5 eating disorder diagnoses were identified, and studies investigating the impact of the COVID-19 pandemic on prevalence or incidence of eating disorders in these countries are needed.

Abstract
Eating disorders (EDs) are debilitating health conditions and common across cultures. Recent reports suggest that about 14.0% of university students in Malaysia are at risk for developing an ED, and that prevalence may differ by ethnicity and gender. However, less is known about the prevalence of EDs in nonuniversity populations. OBJECTIVE The current study seeks to (1) estimate the prevalence of EDs and ED risk status among adults in Malaysia using an established diagnostic screen; (2) examine gender and ethnic differences between ED diagnostic/risk status groups; and (3) characterize the clinical profile of individuals who screen positive for an ED. METHOD We administered the Stanford-Washington University Eating Disorder Screen, an online ED screening tool, to adults in Malaysia in September 2020. RESULTS ED risk/diagnostic categories were assigned to 818 participants (ages 18-73 years) of which, 0.8% screened positive for anorexia nervosa, 1.4% for bulimia nervosa, 0.1% for binge-ED, 51.4% for other specified feeding or ED, and 4.8% for avoidant/restrictive food intake disorder. There was gender parity in the high risk and the overall ED categories. The point prevalence of positive eating pathology screening among Malays was significantly higher than Chinese but no different from Indians. DISCUSSION This is the first study to estimate the prevalence of EDs using a diagnostic screen in a population-based sample of Malaysians. It is concerning that over 50% of Malaysians reported symptoms of EDs. This study highlights the need to invest more resources in understanding and managing eating pathology in Malaysia. PUBLIC SIGNIFICANCE This study estimates the prevalence of EDs among adults in Malaysia using an online EDs screen. Over 50% of Malaysians report symptoms of EDs. The study highlights the need for more resources and funding to address this important public health issue through surveillance, prevention, and treatment of EDs in Malaysia.

Abstract
The Clinical Impairment Assessment (CIA) is the most widely used instrument for assessing psychosocial impairment related to eating disorders (EDs). The CIA was translated into Chinese based on standard procedures. The psychometric properties of the Chinese CIA (C-CIA) were assessed among four adolescent and adult samples [i.e., 792 junior high school students (47.0% boys; Mage = 13.09 years), 1324 senior high school students (44.2% boys; Mage = 16.06 years), 812 undergraduate students (36.3% boys; Mage = 18.88 years), and 406 male adults from a general population (Mage = 28.53 years)]. The three-factor structure of the CIA was replicated. Excellent internal consistencies of the C-CIA were revealed, α = 0.93-0.98. The C-CIA showed moderate and good test-retest reliability in a six-month interval for junior high school students (ICC = 0.69) and senior high school students (ICC = 0.76), respectively. The C-CIA had good test-retest reliability in a two-week interval for undergraduate students (ICC = 0.78) and general adult men (ICC = 0.81). Our results supported good construct validity, known-group validity of the C-CIA, and measurement invariance across sex and age. These findings suggest that the C-CIA can be a useful tool assessing psychosocial impairment related to EDs for Chinese adolescents, young adults, and adult men.

Abstract
This study aimed to determine whether smartphone addiction and depression sequentially mediate the relationship between body dissatisfaction and disordered eating behaviors (e.g., restrained eating, emotional eating and external eating). A total of 5986 participants (54.1% females, average age = 19.8 years, age range = 17–32) completed the Satisfaction and Dissatisfaction with Body Parts Scale, the Three-Factor Eating Questionnaire, the Smartphone Addiction Scale and the Patient Health Questionnaire-9. Mediational analysis showed that, after controlling for age, sex and body mass index, body dissatisfaction was related to disordered eating behaviors through (a) the mediating effect of smartphone addiction, (b) the mediating effect of depression, and (c) the serial mediating effect of smartphone addiction and depression. In conclusion, our study showed for the first time that smartphone addiction and depression can be sequential mediator variables in the association between body dissatisfaction and disordered eating. However, this study is a cross-sectional study; future longitudinal studies could further test the causal associations between these study variables.

Abstract
BACKGROUND Many previous studies have investigated the risk factors associated with eating disorders (EDs) from the perspective of emotion regulation (ER). However, limited research has investigated interactions between co-existing risk factors for EDs, especially in China where research in EDs is underrepresented. METHODS This study examined core risk factors related to maladaptive eating behaviors and ER, and how their interactions affect the detection of EDs. Using machine learning, a decision tree model was constructed on a data set of 830 non-clinical Chinese young women with an average age of 18.91 years (SD = 0.95). The total data set was split into training and testing data sets with a ratio of 70 to 30%. RESULTS Body image inflexibility was identified as the major classifier for women at high risk of EDs. Furthermore, interactions between body image inflexibility, psychological distress, and body dissatisfaction were important in detecting women at high risk of EDs. Overall, the model classifying women at high-risk for EDs had a sensitivity of 0.88 and a specificity of 0.85 when applied to the testing data set. CONCLUSIONS Body image inflexibility, psychological distress, and body dissatisfaction were identified as the major classifiers for young women in China at high risk of EDs. Researchers and practitioners may consider these findings in the screening, prevention, and treatment of EDs among young women in China.

Abstract
An overview of eating and feeding disorders according to the future criteria of the International Classification of Diseases (ICD-11) is presented, including information on differential diagnosis, epidemiology, etiology, pathogenesis as well as therapy. Binge-eating disorder is new and the most frequent eating disorder. While anorexia nervosa and bulimia nervosa mostly affect women, the gender ratio in binge-eating disorder is more balanced. Concerning etiology, socio-cultural, biological and psychological factors are discussed. Cognitive behavioral psychotherapy is the best-validated treatment for all three eating disorders. According to the German guidelines for treatment (2019), focal psychodynamic psychotherapy is also a treatment option for anorexia nervosa. Evidence for the positive effect of psychopharmacologic drugs in the treatment of anorexia nervosa is still lacking. Fluoxetine has been shown to have a limited effect in the treatment of bulimia nervosa.

Abstract
OBJECTIVE This study explored treatment experiences and social support among individuals with eating disorders (EDs) in mainland China. METHOD Subscribers of a Chinese online social media platform (WeChat) focused on EDs were invited to complete a screening questionnaire that included the Eating Disorder Diagnostic Scale for the DSM-5. Of the 116 questionnaire responses, 31 met inclusion criteria for follow-up interviews. Individuals who never sought treatment were not eligible for follow-up interviews, but provided brief explanations about why they did not seek treatment. All eligible participants (n = 31) completed a semi-structured interview about their experiences with ED treatment and social support. Qualitative data from the interviews and survey responses regarding not seeking treatment were subjected to inductive data-driven thematic analysis with deductive coding to illuminate treatment and social support experiences or reasons for not seeking treatment. RESULTS Themes emerged from interviews revealed positive inpatient treatment experiences for anorexia nervosa, but negative outpatient treatment experiences, unaffordable care, and ineffective psychopharmacological treatments. Parents, friends, and partners were sources of social support, but participants largely felt misunderstood or blamed by these same entities. Shame, not recognizing ED as an illness, and financial constraints were listed as the primary reasons for not seeking treatment. DISCUSSION The importance of hearing patients' perspectives, improving ED literacy in China, increasing knowledge of culturally specific manifestations of EDs, and developing culturally responsive services and dissemination of treatment resources are emphasized.

Abstract
INTRODUCTION Skin findings such as acne, hypertrichosis, and hyperpigmentation may be a clue for the diagnosis of eating disorders. There are studies on skin findings in eating disorders, but there is no study evaluating eating disorders in acne patients. We aimed to investigate eating disorders in acne patients and evaluate the effect of acne severity, quality of life, and body mass index (BMI) on eating disorders. METHODS Two hundred thirty-two acne patients and 314 healthy controls were enrolled. Acne severity was detected according to Grading Acne Severity Scale (GAGS) by the dermatologists. Eating Attitude Test-40 (EAT) and Acne Quality of Life Scale (AQLS) were filled out by patients. The controls filled out EAT. Individuals scoring EAT≥30 points were considered at risk for eating disorders. RESULTS The median EAT score (15 vs. 13) and the number of patients scoring EAT ≥30 (14.2% vs. 2.2%) were found to be significantly higher in the patients' group compared with control group (p: 0.005, p < 0.001). There was a significant positive correlation between EAT score and AQLS score but no significant relationship between acne severity and EAT score. A significant positive correlation was found between EAT scores and BMI. CONCLUSION Eating disorders and acne are mostly seen in adolescence, and both have high biopsychosocial morbidity. Also eating disorders can even be mortal sometimes. There are common psychopathological mechanisms in eating disorders and acne.

Abstract
BACKGROUND Urinary creatinine can be used to adjust urinary iodine to evaluate iodine nutritional status during pregnancy. However, the reference intervals and impact factors of urinary creatinine are unknown. METHODS 24 h urine creatinine concentration (24 hUCr) and spot UCr at four different time periods of the day of pregnant women from Part 1 (n = 743) were measured. Linear regression analysis was performed to identify the impact factors of 24 h urinary creatinine excretion (24 hUCrE) and obtain the estimated 24 h urinary creatinine excretion (24 hUCrEest). Then measured urinary iodine concentration (UIC) of 24 h and at fasting of pregnant women from Part 2 (n = 325), used spot urinary iodine to creatinine concentration ratio (UIC/UCr) and 24 hUCrEest to calculate the estimated 24 h urinary iodine excretion (24 hUIEest), finally checked the consistency and correlation of 24 hUIEest and 24 h urinary iodine excretion (24 hUIE). RESULTS In Part 1, the median 24 hUCrE was 1.24(IQR0.98-1.76)g, and the reference interval was 0.61-2.93 g. The median 24 hUCr was 0.76 (IQR0.57-1.01)g/L, and the reference interval was 0.36-1.88 g/L. Multiple linear regression results showed that pregnancy weight was an influencing factor to 24 hUCrE after adjusting by gestational weeks, age, pre-pregnancy BMI, and percentage of body fat (F = 45.029, p<0.001). In Part 2, there was no statistically significant difference between 24 hUIEest and 24 hUIE (Z =-0.767, p = 0.443). Using 24hUIE as the gold standard, the relative average difference in 24hUIEest was 4.2 %, the relative average differences for UIC and UIC/UCr were 32.4 % and 37.2 %. The reference interval of 24 hUIE and 24 hUIEest were 88.43-585.90 μg and 50.97-700.39 μg, respectively. CONCLUSIONS The reference intervals of 24 hUCrE, spot UCr, 24 hUIE, and 24 hUIEest during pregnancy were established. 24 hUCrE has important application value in iodine nutrition evaluation to gain more lead time for pregnant women with iodine nutrition-related diseases.

[PMID: 33663608 PMCID: PMC7934560 DOI: 10.1186/s40337-021-00385-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 02/18/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Few studies have investigated the epidemiology of eating disorders using national representative data. In this study, we investigated the treatment prevalence and economic burden of eating disorders in South Korea. METHODS The aim of this study was to estimate the treatment prevalence and the medical expenditure of diagnosed eating disorders (ICD F50.x) in South Korea between 2010 and 2015. We also examined the economic costs of eating disorders, including the direct medical cost, direct non-medical costs, and indirect costs, in order to calculate the economic burden of such disorders. RESULTS The total treatment prevalence of eating disorders in South Korea was 12.02 people (per 100,000) in 2010, and 13.28 in 2015. The cost of medical expenditures due to eating disorders increased from USD 1229724 in 2010 to USD 1843706 in 2015. The total economic cost of eating disorders was USD 5455626 in 2015. In 2015, the economic cost and prevalence of eating disorders was the highest in the 20-29 age group. CONCLUSIONS The results showed the eating disorders are insufficiently managed in the medical insurance system. Further research is therefore warranted to better understand the economic burdens of each type of eating disorder.

The Role of Problematic Smartphone Uses and Psychological Distress in the Relationship Between Sleep Quality and Disordered Eating Behaviors Among Chinese College Students. Front Psychiatry 2021; 12:793506. [PMID: 34966312 PMCID: PMC8710586 DOI: 10.3389/fpsyt.2021.793506] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 11/19/2021] [Indexed: 12/11/2022] Open
Abstract
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.

Screen-detected disordered eating and related traits in a large population sample of females in mainland China: China Health and Nutrition Survey. Int J Eat Disord 2021; 54:24-35. [PMID: 33191528 PMCID: PMC7855662 DOI: 10.1002/eat.23409] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 10/23/2020] [Accepted: 10/24/2020] [Indexed: 12/30/2022]
Abstract
OBJECTIVE We describe the prevalence and sociodemographic factors associated with screen-detected disordered eating and related traits in a population-based sample of women in China. We also explored prevalence trends over time. METHOD A total of 4,218 females aged 12-50 were sampled from 15 provinces as part of the China Health and Nutrition Survey (CHNS) in 2015. The SCOFF questionnaire screened for disordered eating and the selected questions from the Eating Disorders Examination-Questionnaire measured dietary restraint, shape concerns, and weight concerns. Body mass index (BMI) was measured and sociodemographic factors captured urban/rural residence, age, ethnicity, income, education, marital status, and occupational status. We calculated the prevalence of screen-detected disordered eating and related traits broadly and across several dimensions and compared prevalence estimates to 2009 and 2011 reports. RESULTS We detected 296 individuals who screened positive for disordered eating on the SCOFF (prevalence = 7.04%). Positive screens were associated with urban residence (p = .002) and higher education levels (p < .001). Scores on restraint, shape concerns, and weight concerns were all higher for individuals in urban versus village locations (all p's < .001), and with higher BMI (p < .001) for shape and weight concerns. The prevalence of screen-detected disordered eating increased numerically across 2009, 2011, and 2015. DISCUSSION The prevalence of screen-detected disordered eating in mainland China was comparable to other populations worldwide obtained from a recent meta-analysis. The distribution of disordered eating and related traits varied by several sociodemographic factors, which include age, BMI, urban/rural residence, education, and income, suggesting important directions for case detection and intervention in China.
