Abstract
Obesity has become a major public health issue in China. Overweight and obesity have increased rapidly in the past four decades, and the latest national prevalence estimates for 2015-19, based on Chinese criteria, were 6·8% for overweight and 3·6% for obesity in children younger than 6 years, 11·1% for overweight and 7·9% for obesity in children and adolescents aged 6-17 years, and 34·3% for overweight and 16·4% for obesity in adults (≥18 years). Prevalence differed by sex, age group, and geographical location, but was substantial in all subpopulations. Strong evidence from prospective cohort studies has linked overweight and obesity to increased risks of major non-communicable diseases and premature mortality in Chinese populations. The growing burden of overweight and obesity could be driven by economic developments, sociocultural norms, and policies that have shaped individual-level risk factors for obesity through urbanisation, urban planning and built environments, and food systems and environments. Substantial changes in dietary patterns have occurred in China, with increased consumption of animal-source foods, refined grains, and highly processed, high-sugar, and high-fat foods, while physical activity levels in all major domains have decreased with increasing sedentary behaviours. The effects of dietary factors and physical inactivity intersect with other individual-level risk factors such as genetic susceptibility, psychosocial factors, obesogens, and in-utero and early-life exposures. In view of the scarcity of research around the individual and collective roles of these upstream and downstream factors, multidisciplinary and transdisciplinary studies are urgently needed to identify systemic approaches that target both the population-level determinants and individual-level risk factors for obesity in China.

Detection, treatment, and course of eating disorders in Finland: A population-based study of adolescent and young adult females and males. EUROPEAN EATING DISORDERS REVIEW 2021; 29:720-732. [PMID: 34008267 PMCID: PMC8349843 DOI: 10.1002/erv.2838] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 03/22/2021] [Accepted: 04/26/2021] [Indexed: 11/17/2022]
Abstract
Objective: We assessed the detection, treatment and outcomes of DSM-5 eating disorders in a nationwide community setting. Method: The FinnTwin12 cohort comprises twins born in 1983–1987 in Finland (n = 5,600), with follow-up starting at age 12. We outline treatment and outcomes of the 127 females and 15 males diagnosed with a lifetime DSM-5 eating disorder in interviews conducted for a subsample (n = 1,347) in their early 20s. Results: Only 45 (32%) of those diagnosed with eating disorder in the interviews had their condition detected in healthcare, and even fewer received treatment (30% of females, 13% of males). Anorexia nervosa (AN), bulimia nervosa, and atypical AN were detected and treated more often than other eating disorders. Five years after disease onset, 41% of those diagnosed had recovered. There were no statistically significant differences in the course of different eating disorders (log-rank p = 0.66) but the outcome was more favourable among males (log-rank p = 0.008). The likelihood of 5-year recovery did not differ between those who had and who had not received treatment (41.1% vs. 40.5%, log-rank p = 0.66). Conclusion: Although eating disorders are common and symptoms are persistent for many, they remain under-diagnosed and under-treated. In real-world settings, effectiveness of provided treatments may be limited.

Abstract
Pica, the developmentally and culturally-inappropriate eating of non-nutritive and non-food substances, is most often documented in people with developmental disabilities and children, frequently in institutional and residential settings. To date, there are no randomized clinical trials on pica-specific treatments, and very little literature is available regarding the characteristics or treatment of pica in adults with no intellectual or social deficits, and co-morbid disorders. This case study addresses this gap, and involves a highly educated 30 year-old American woman with foam rubber pica and burned match consumption (cautopyreiophagia) behaviors, along with co-morbid depressive, anxiety, and obsessive-compulsive symptoms, who received treatment in a general intensive outpatient program for adults in a large urban community psychiatry setting. The case study describes how the Biosocial Theory and Transtheoretical Model of Health Behavior Change were used to conceptualize this woman’s symptoms and guide a treatment team of clinicians who did not specialize in pica. Providers in non-specialty clinic settings would benefit from reflecting on ways to adapt evidence-based techniques to the treatment of uncommon symptoms.

Abstract
Objective Network theory considers mental disorders as the product of symptom interaction. A growing number of studies employing this methodology has been conducted in eating disorders (EDs). We aimed to review those studies to provide evidence and limitations for a novel conceptualisation of EDs. Methods According to PRISMA guidelines and PICOS criteria, studies eligible for inclusion were those employing network analysis in people with a clinically defined diagnosis of ED. Twenty‐five studies were included and were analysed in relation to diagnosis, comorbidity, and treatment outcome. Results Despite the central role of overvaluation of body shape and weight and cognitive restraint across ED diagnoses, ineffectiveness, interoceptive awareness and affective problems appear central symptoms. Ineffectiveness and interoceptive awareness emerge as bridge symptoms promoting comorbidity in people with anorexia nervosa and in mixed ED samples. Although few studies assessed treatment outcome, there is evidence supporting the predictive role of central network nodes. Conclusions Ineffectiveness, interoceptive ability and affective problems may be included in the core ED psychopathology, in addition to ED‐specific symptoms. Network analysis is a promising method to reconceptualize comorbidity. Future studies are recommended to include general psychopathology in ED networks, to assess connections with the external field and clinical meaning of network connectivity. Overvaluation of body shape and weight and cognitive restraint appear as central nodes across eating disorder diagnoses and ages. In addition to specific symptoms, ineffectiveness, low interoceptive ability and affective problems also emerge as central nodes in eating disorders. There is some evidence to point to ineffectiveness and low interoceptive ability as bridge nodes promoting psychiatric comorbidity. Only few studies assessed treatment outcome through the network analysis approach

Abstract
PURPOSE Evidence concerning eating disorders as risk toward developing cancer is sparse. Energy restriction might be cancer protective, while malnutrition, vomiting, laxative and substance use might stimulate cancer development. We examined whether individuals with an eating disorder (not restricted to anorexia nervosa) had a different risk of developing cancer. METHODS A systematic search on Medline and Embase until 28th April 2020 identified relevant human original research publications, including all populations and all cancer types. RESULTS From 990 records, 6 case reports and 9 cohorts were included. Some cohorts found a decreased breast (3/5 studies) or cervical (1/2) cancer risk, while an increased esophageal (2/3), liver (1/1), brain (1/1 in men) and respiratory (2/4) cancer risk, but other cancer risks were non-significant, and an increased mortality overall (1/2), from breast (1/1), female genital (1/1) and skin (1/1) cancer in eating disorder patients. The case reports further described esophageal cancer and leukemia. No clear statistical differences in cancer risk were found depending on eating disorder type, perhaps due to the small sample size (n = 1783 for other than anorexia nervosa). CONCLUSIONS The literature on eating disorders and cancer risk is sparse with many gaps. Hormonal changes, sexual activity, nutritional status, vomiting and concomitant tobacco/alcohol abuse may explain increased/decreased cancer risk. Future large studies (now 1-366 cancer cases) that also include men (now 4.7%), bulimia nervosa (now 3.8%) and several cancer sites (now mainly breast cancer) are needed and should foresee longer follow-up time (now 5.4-15.2 years) and extensive confounder adjustment (now only age and sex). LEVEL OF EVIDENCE Level I, systematic review.

Abstract
Although a number of studies have been conducted on the association of -1438A/G polymorphism in serotonin 2A receptor (5-HTR2A) gene with anorexia nervosa (AN) and bulimia nervosa (BN), the results remained inconsistent. We thus performed a meta-analysis to clarify the effects of -1438A/G polymorphism on the risk of AN and BN. PubMed, Embase, the Cochrane Library, CNKI, Weipu and Wanfang databases were searched for eligible studies. Pooled odds ratio (OR) and 95 % confidence interval (CI) were calculated to estimate the strength of the association. Subgroup analysis was also performed by ethnicity. In total, 17 studies were included for the meta-analysis, of which 15 studies containing 2028 cases and 2725 controls were used for AN analysis and 7 studies containing 505 cases and 1129 controls for BN analysis. The results showed -1438A/G polymorphism was significantly associated with the risk of AN in four genetic models (allele model, A vs. G: OR = 1.31, 95 % CI = 1.11-1.64, P = 0.003; recessive model, AA vs. GA + GG: OR = 1.69, 95 % CI = 1.28-2.23, P = 0.000; dominant model, AA + GA vs. GG: OR = 1.35, 95 % CI = 1.02-1.79, P = 0.037; co-dominant model, AA vs. GG: OR = 1.94, 95 % CI = 1.29-2.92, P = 0.002) in Caucasians, but not in Asians. We failed to observe a significant association between -1438A/G polymorphism and the risk of BN either in overall or in Caucasian population. The present meta-analysis indicated that A allele and AA genotype of 5-HTR2A -1438A/G polymorphism may contribute to higher risk of AN, especially in Caucasians. However, this polymorphism was not associated with the susceptibility to BN.

Abstract
Skills trainings for caregivers of patients with anorexia nervosa (AN) have been proven to be effective in improving caregiver skills and reducing caregivers’ psychopathology. The effects on patients, especially adolescents, are largely unknown. The aim of this study was to evaluate the effectiveness of a caregivers’ skills training program (Supporting Carers of Children and Adolescents with Eating Disorders in Austria, SUCCEAT, workshop or online version) on adolescents with AN delivered as workshops (WS) or online (ONL). Outcomes are Body-Mass-Index (BMI) percentile, eating psychopathology (Eating Disorder Examination, EDE), attitudinal and behavioural dimensions of eating disorders (Eating Disorder Inventory-2), motivation to change (AN Stages of Change Questionnaire), emotional and behavioural problems (Youth Self-Report) and quality of life (KINDL). All outcome variables significantly improved across both SUCCEAT groups (WS and ONL) and were sustained at 12-month follow-up. The online and workshop delivery of SUCCEAT were equally effective. Most effect sizes were in the medium-to-high range. Full or partial remission was observed in 72% (WS) and 87% (ONL) of patients. Caregiver skills trainings, either delivered as workshops or online modules, are highly recommended to complement treatment as usual.

Parental eating disorders: A systematic review of parenting attitudes, behaviours, and parent-child interactions. Clin Psychol Rev 2021; 88:102031.

Abstract
A substantial proportion of adults with eating disorders are parents. Studies suggest these parents may experience a range of parenting challenges, and their children may be at an increased risk for the development of eating disorders themselves. With parenting practices being one potential environmental mechanism for the intergenerational transmission of eating disorders, we systematically searched Scopus, Web of Science, PubMed, MEDLINE, PsychINFO, and PsychArticles for controlled studies in which parenting attitudes, behaviours, and parent-child interactions were examined for parents with and without probable eating disorders. 26,512 abstracts were screened, and 167 full-text manuscripts were retrieved, with 33 studies meeting the review inclusion criteria. Studies suggest that parents with eating disorders experience higher levels of parenting stress than control parents, and may on average be more intrusive, less sensitive, and provide less structuring/facilitation in non-feeding interactions with their children. These parents also appear, on average, to experience increased concern about their children's weight, and parent-child mealtime interactions may be problematic and characterised by high levels of conflict. Suggestions for future research are made with a view to enhancing understandings of the intergenerational transmission of eating disorders, which may lead to the identification of intervention targets for parents with eating disorders and their children.

Abstract
This study examined the resting-state functional network connectivity underlying eating disorder symptoms in a large sample of healthy young adults (n = 693). Individuals with higher levels of eating disorder symptoms displayed weaker intra-network connectivity of the executive control network and basal ganglia network, as well as weaker inter-network connectivity in the three examined networks (i.e., the executive control network, basal ganglia network, and default mode network). The findings suggest that these neural circuits may play a key role in symptoms of disordered eating in healthy adults. They further reveal that the less efficient information exchange within and between intrinsic networks associated with self-referential thinking, inhibitory control, and reward sensitivity are strongly related to eating disorder symptoms.
Previous neuroimaging research of eating disorders such as anorexia nervosa and bulimia nervosa has mainly focused on clinical patients, indicating the crucial role of intrinsic connectivity networks involved in aberrant behavioral control (i.e., executive control network), reward reactivity (i.e., basal ganglia network), and excessive self-focused and body-focused ruminations (i.e., default mode network) in the onset and maintenance of eating disturbances. However, examinations of large-scale resting-state networks that support the role of cognitive control, reward sensitivity, and self-directed thinking in disordered eating have rarely involved non-clinical samples from the general population. This study, involving a total of 693 healthy young adults (68.69% females; mean age, 18.37 years), investigated these issues by using pre-defined functional regions of interest from the executive control network, basal ganglia network, default mode network, and a seed-based region of interest-to-region of interest approach. After statistically controlling for differences in age, sex, body mass index, and head motion, we observed significant associations of higher levels of eating disorder symptoms, especially bulimia-type eating (i.e., binge eating and a combination of binge eating and compensatory behaviors, such as purging via self-induced vomiting or laxative use, and compulsive exercise), with weaker intra-network and inter-network functional synchrony. These results remained significant after excluding underweight, overweight, and obese participants. These findings suggest that these neural circuits may play a key role in the symptoms of disordered eating in healthy adults. They further reveal that the less efficient information exchange within and between intrinsic networks associated with self-referential thinking, inhibitory control, and reward sensitivity are strongly related to eating disorder symptoms.

JMIR Serious Games 2021; 9:e24998. [PMID: 33847593 PMCID: PMC8057519 DOI: 10.2196/24998] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Revised: 02/15/2021] [Accepted: 03/13/2021] [Indexed: 12/30/2022] Open
Abstract
Background Anorexia nervosa is one of the more severe eating disorders, which is characterized by reduced food intake, leading to emaciation and psychological maladjustment. Treatment outcomes are often discouraging, with most interventions displaying a recovery rate below 50%, a dropout rate from 20% to 50%, and a high risk of relapse. Patients with anorexia nervosa often display anxiety and aversive behaviors toward food. Virtual reality has been successful in treating vertigo, anxiety disorder, and posttraumatic stress syndrome, and could potentially be used as an aid in treating eating disorders. Objective The aim of this study was to evaluate the feasibility and usability of an immersive virtual reality technology administered through an app for use by patients with eating disorders. Methods Twenty-six participants, including 19 eating disorder clinic personnel and 5 information technology personnel, were recruited through emails and personal invitations. Participants handled virtual food and utensils on an app using immersive virtual reality technology comprising a headset and two hand controllers. In the app, the participants learned about the available actions through a tutorial and they were introduced to a food challenge. The challenge consisted of a meal type (meatballs, potatoes, sauce, and lingonberries) that is typically difficult for patients with anorexia nervosa to eat in real life. Participants were instructed, via visual feedback from the app, to eat at a healthy rate, which is also a challenge for patients. Participants rated the feasibility and usability of the app by responding to the mHealth Evidence Reporting and Assessment checklist, the 10-item System Usability Scale, and the 20-point heuristic evaluation questionnaire. A cognitive walkthrough was performed using video recordings of participant interactions in the virtual environment. Results The mean age of participants was 37.9 (SD 9.7) years. Half of the participants had previous experience with virtual reality. Answers to the mHealth Evidence Reporting and Assessment checklist suggested that implementation of the app would face minor infrastructural, technological, interoperability, financial, and adoption problems. There was some disagreement on intervention delivery, specifically regarding frequency of use; however, most of the participants agreed that the app should be used at least once per week. The app received a mean score of 73.4 (range 55-90), earning an overall “good” rating. The mean score of single items of the heuristic evaluation questionnaire was 3.6 out of 5. The lowest score (2.6) was given to the “accuracy” item. During the cognitive walkthrough, 32% of the participants displayed difficulty in understanding what to do at the initial selection screen. However, after passing the selection screen, all participants understood how to progress through the tasks. Conclusions Participants found the app to be usable and eating disorder personnel were positive regarding its fit with current treatment methods. Along with the food item challenges in the current app, participants considered that the app requires improvement to offer environmental and social (eg, crowded room vs eating alone) challenges.

Abstract
OBJECTIVE Binge-eating disorder (BED) was established as a diagnosis in 2013 with the DSM-5 and has been included in the ICD-11 in 2018. In adulthood, BED is prevalent and correlated with somatic and mental health problems. Less is known about BED in adolescence, although this age period could represent a window of opportunity for early intervention. This study aimed to investigate the 1-year prevalence, correlates, and impact of BED symptoms in a community sample of adolescents. METHOD We included 1,404 girls and 1,105 boys from the 16-years-follow-up of the Copenhagen Child Cohort study, CCC2000. The adolescents self-reported on BED symptoms, weight-status, body perception, mental health problems, and self-rated impact of food and weight-related thoughts and behaviors. Information about socio-economic factors and hospital diagnosed psychiatric disorders were obtained from national registries. RESULTS A total of 8.5% reported weekly overeating with loss of control (10.9% of girls, 4.8% of boys), and 2.6% (3.6% of girls, 1.2% of boys) reported symptoms consistent with BED according to the DSM-5. Regardless of sex, BED was correlated with concurrent overweight, body-dissatisfaction, low self-esteem, and mental health problems, especially emotional, but also with problems of behavior, inattention, and peer-relations, and with high self-rated impact on everyday life. Immigrant background and lower socio-economy were potential risk factors for BED in boys in this sample. DISCUSSION BED was prevalent and correlated with mental health problems and overall impact among adolescents in this community sample, indicating the need for clinical attention and intervention towards binge-eating disorder in the adolescent period.

Comparative efficacy and acceptability of psychological interventions for the treatment of adult outpatients with anorexia nervosa: a systematic review and network meta-analysis. Lancet Psychiatry 2021; 8:215-224. [PMID: 33600749 DOI: 10.1016/s2215-0366(20)30566-6] [Citation(s) in RCA: 81] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 11/25/2020] [Accepted: 12/07/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND No consistent first-option psychological interventions for adult outpatients with anorexia nervosa emerges from guidelines. We aimed to compare stand-alone psychological interventions for adult outpatients with anorexia nervosa with a specific focus on body-mass index, eating disorder symptoms, and all-cause dropout rate. METHODS In this systematic review and network meta-analysis, we assessed randomised controlled trials about stand-alone pharmacological or non-pharmacological treatments of adult outpatients with anorexia nervosa, defined according to standardised criteria, with data for at least two timepoints relating to either body-mass index or global eating disorder psychopathology. We searched Cochrane CENTRAL, CINAHL, MEDLINE, and PsychINFO for published and unpublished literature from inception until March 20, 2020. The primary outcomes were the change in body mass index and clinical symptoms, and the secondary outcome was all-cause dropout rate, which were all assessed for treatment as usual, cognitive behavioural therapy (CBT), Maudsley anorexia treatment for adults, family-based treatment, psychodynamic-oriented psychotherapies, a form of CBT targeting compulsive exercise, and cognitive remediation therapy followed by CBT. Global and local inconsistencies for the network meta-analysis were measured, and CINeMA was used to assess the confidence in evidence for primary outcomes. The protocol is registered in PROSPERO (CRD42017064429). FINDINGS Of 14 003 studies assessed for their title and abstract, 16 (0·1%) randomised controlled trials for psychological treatments were included in the systematic review, of which 13 (0·1%) contributed to the network meta-analysis, with 1047 patients in total (of whom 1020 [97·4%] were female). None of the interventions outperformed treatment as usual in our primary outcomes, but the all-cause dropout rate was lower for CBT than for psychodynamic-oriented psychotherapies (OR 0·54, 95% CI 0·31-0·93). Heterogeneity or inconsistency emerged only for a few comparisons. Confidence in the evidence was low to very low. INTERPRETATION Compared with treatment as usual, specific psychological treatments for adult outpatients with anorexia nervosa can be associated with modest improvements in terms of clinical course and quality of life, but no reliable evidence supports clear superiority or inferiority of the specific treatments that are recommended by clinical guidelines internationally. Our analysis is based on the best data from existing clinical studies, but these findings should not be seen as definitive or universally applicable. There is an urgent need to fund new research to develop and improve therapies for adults with anorexia nervosa. Meanwhile, to better understand the effects of available treatments, participant-level data should be made freely accessible to researchers to eventually identify whether specific subgroups of patients are more likely to respond to specific treatments.

Comorbidity of self-harm and disordered eating in young people: Evidence from a UK population-based cohort. J Affect Disord 2021; 282:386-390.

Abstract
BACKGROUND Self-harm and eating disorders are often comorbid in clinical samples but their co-occurrence in the general population is unclear. Given that only a small proportion of individuals who self-harm or have disordered eating present to clinical services, and that both self-harm and eating disorders are associated with substantial morbidity and mortality, it is important to study these behaviours at a population level. METHODS We assessed the co-occurrence of self-harm and disordered eating behaviours in 3384 females and 2326 males from a UK population-based cohort: the Avon Longitudinal Study of Parents and Children (ALSPAC). Participants reported on their self-harm and disordered eating behaviours (fasting, purging, binge-eating and excessive exercise) in the last year via questionnaire at 16 and 24 years. At each age we assessed how many individuals who self-harm also reported disordered eating, and how many individuals with disordered eating also reported self-harm. RESULTS We found high comorbidity of self-harm and disordered eating. Almost two-thirds of 16-year-old females, and two-in-five 24-year old males who self-harmed also reported some form of disordered eating. Young people with disordered eating reported higher levels of self-harm at both ages compared to those without disordered eating. LIMITATIONS We were not able to measure whether participants identified their disordered eating as a method of self-harm. CONCLUSIONS Self-harm and disordered eating commonly co-occur in young people in the general population. It is important to screen for both sets of difficulties to provide appropriate treatment.

Abstract
Background Proper regulation of feeding is important for an organism’s well-being and survival and involves a motivational component directing the search for food. Dissecting the molecular and neural mechanisms of motivated feeding behavior requires assays that allow quantification of both motivation and food intake. Measurements of motivated behavior usually involve assessing physical effort or overcoming an aversive stimulus. Food intake in Drosophila can be determined in a number of ways, including by measuring the time a fly’s proboscis interacts with a food source associated with an electrical current in the fly liquid-food interaction counter (FLIC). Here, we show that electrical current flowing through flies during this interaction is aversive, and we describe a modified assay to measure motivation in Drosophila. Results Food intake is reduced during the interaction with FLIC when the electrical current is turned on, which provides a confounding variable in studies of motivated behavior. Based on the FLIC, we engineer a novel assay, the fly liquid-food electroshock assay (FLEA), which allows for current adjustments for each feeding well. Using the FLEA, we show that both external incentives and internal motivational state can serve as drivers for flies to overcome higher current (electric shock) to obtain superior food. Unlike similar assays in which bitterness is the aversive stimulus for the fly to overcome, we show that current perception is not discounted as flies become more food-deprived. Finally, we use genetically manipulated flies to show that neuropeptide F, an orthologue of mammalian NPY previously implicated in regulation of feeding motivation, is required for sensory processing of electrical current. Conclusion The FLEA is therefore a novel assay to accurately measure incentive motivation in Drosophila. Using the FLEA, we also show that neuropeptide F is required for proper perception or processing of an electroshock, a novel function for this neuropeptide involved in the processing of external and internal stimuli.

Abstract
BACKGROUND This study aims to examine the underlying associations between eating, affective and metacognitive symptoms in patients with binge eating disorder (BED) through network analysis (NA) in order to identify key variables that may be considered the target for psychotherapeutic interventions. METHODS A total of 155 patients with BED completed measures of eating psychopathology, affective symptoms, emotion regulation and metacognition. A cross-sectional network was inferred by means of Gaussian Markov random field estimation using graphical LASSO and the extended Bayesian information criterion (EBIC-LASSO), and central symptoms of BED were identified by means of the strength centrality index. RESULTS Impaired self-monitoring metacognition and difficulties in impulse control emerged as the symptoms with the highest centrality. Conversely, eating and affective features were less central. The centrality stability coefficient of strength was above the recommended cut-off, thus indicating the stability of the network. CONCLUSIONS According to the present NA findings, impaired self-monitoring metacognition and difficulties in impulse control are the central nodes in the psychopathological network of BED whereas eating symptoms appear marginal. If further studies with larger samples replicate these results, metacognition and impulse control could represent new targets of psychotherapeutic interventions in the treatment of BED. In light of this, metacognitive interpersonal therapy could be a promising aid in clinical practice to develop an effective treatment for BED.

Abstract
Alterations in the gut microbiome and fecal metabolites have been detected in anorexia nervosa (AN), but differences in those profiles between restricting AN (ANR) and binge-purging AN (ANBP) type have not been explored. We made a secondary analysis of our previous data concerning microbiome and metabolomics profiles of 17 ANR women, six ANBP women and 20 healthy controls (HC). Twelve fecal metabolites differentiating ANR patients, ANBP patients and HC were identified. Both patient groups showed decreased intra-individual bacterial richness with respect to healthy controls (HC). Compared to ANR subjects, ANBP patients had a significant increase in relative abundances of Bifidobacterium, Bifidobacteriaceae, Bifidobacteriales, and Eubacteriacae and a significant decrease in relative abundances of Odoribacter, Haemophilus, Pasteurellaceae, and Pasteurellales. The heatmaps of the relationships of selected fecal metabolites with microbial families showed different structures among the three groups, with the heatmap of ANBP patients being drastically different from that of HC, while that of ANR patients resulted more similar to HC. These findings, although preliminary because of the relatively small sample size, confirm the occurrence of different gut dysbiosis in ANR and ANBP and demonstrate different connections between gut microorganisms and fecal metabolites in the two AN types.

Abstract
Abnormalities of hematological and biochemical parameters are various and frequent during anorexia nervosa, and are mainly related to malnutrition, weight loss, and compensatory purgative behaviors. They are most often moderate and reversible through appropriate nutritional and weight rehabilitation, as well as well-conducted symptomatic treatment. Severe abnormalities are rarer, but are potentially serious or even fatal. Isolated moderate anemia and leukopenia are frequently noted, with thrombocytopenia being less frequent. Severe, bi-cytopenic, pancytopenic, and spinal cord injury are less common. They can be explained by the gelatinous transformation of the bone marrow caused by malnutrition. Biochemical abnormalities are typically hydroelectrolytic disorders (hypokalemia, hyponatremia, metabolic alkalosis), acute or chronic renal failure, elevated transaminases, risk of potentially severe hypoglycemia, and elevated lipid parameters. During the refeeding syndrome, hypophosphatemia is characteristic and may be associated with hypomagnesemia and hypocalcemia, and thiamine deficiency. Malnutrition can also lead to alterations in hormone status, including hypothyroidism, hypercorticism and hypogonadism, which may be involved in the development of serious bone conditions such as osteoporosis. These abnormalities should be routinely investigated, monitored, and corrected during anorexia nervosa. Early and multidisciplinary management of this eating disorder is essential to prevent chronicity of the disorder and the potential severity of these abnormalities.

Body image perception, smoking, alcohol use, indoor tanning, and disordered eating in young and middle-aged adults: findings from a large population-based Swedish study. BMC Public Health 2021; 21:128. [PMID: 33435932 PMCID: PMC7802333 DOI: 10.1186/s12889-021-10158-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Accepted: 01/01/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Body image concerns may give rise to a multitude of risk behaviors, such as unhealthy weight control practices, disordered eating behaviors (e.g., compensatory purging or preoccupation with food), smoking, excessive alcohol intake, or sunbed use. However, the distribution of these risk behaviors across adulthood has rarely been studied. METHODS The aim of this study was to explore health risk behaviors as correlates of body image perception in a randomly selected study population of 30,245 individuals aged 30-66 in Stockholm, Sweden, utilizing data from the Stockholm Public Health Cohort. Bivariate correlations were explored and a hierarchic binary logistic regression analysis was performed. RESULTS The prevalence of body image discrepancy was higher among smokers and respondents displaying disordered eating behaviors. In contrast, alcohol and sunbed use were inversely correlated to body image discrepancy. Body mass index was the substantially strongest explanatory factor behind the observed variance in body image discrepancy, followed by loss-of-control eating. Notably, no major gender differences in body image perception were detected. Some unexpected patterns of association between variables other than body image perception, such as those between smoking, alcohol use, and sunbed use, were seen. CONCLUSIONS Overall, the patterns differ substantially from what has previously been found in adolescent and young adult samples, indicating that the synergy and aggregation of risk behaviors observed among younger individuals may not apply to adults aged 30-66.

Abstract
OBJECTIVES Anorexia nervosa is a complex psychiatric disorder that can lead to specific somatic complications. Malnutrition is frequent and can involve a decrease of mobility, up to functional impotence, in individuals with extremely severe cases. The aim of this pilot study was to examine muscle strength and peak expiratory flow (PEF) in severely undernourished patients with anorexia nervosa at admission and after 5 wk of renutrition by tube feeding, and to find the clinical and biological correlates of muscle-strength impairment. METHODS A prospective observational study was conducted over 6 mo. Manual muscle testing, measures of PEF, and clinical and biologic assessments were performed at baseline and after 5 wk of renutrition. RESULTS Twenty-three extremely malnourished female participants (mean body mass index: 11.4 ± 1.3 kg/m2) were included. All participants had global impairment in muscle strength (manual muscle testing: 37.7 ± 7.7) and PEF (253.3 ± 60 mL/min) at admission. Muscle weakness was higher in axial than peripheral muscle groups (P < 0.01), with no significant difference between proximal and distal muscles (P > 0.05). Muscle strength at admission was significantly associated with severity of undernourishment (body mass index and albumin) and transaminitis (P < 0.05). At follow-up, musculoskeletal strength and PEF were significantly improved after partial weight recovery (P < 0.01). CONCLUSIONS Extremely undernourished people with anorexia nervosa present a decrease of PEF and musculoskeletal strength predominant on axial muscles. Both are associated with severity of malnutrition and liver damage. Partial recovery was observed after 5 wk of enteral nutrition.

Abstract
Introduction: Binge eating disorder (BED) is the most common eating disorder, affecting a large population worldwide. It is characterized by recurrent episodes of binge eating, with no compensatory behaviors. BED is often associated with psychiatric comorbidities, and still represents a challenge in terms of treatment strategies. In the last years, neuromodulation has represented a promising approach in the treatment of BED. We report the cases of two women, affected by Bipolar Disorder Type II (BD-II) and comorbid BED, whose BED symptoms improved after a course of accelerated intermittent Theta Burst Stimulation (iTBS). Methods: We carried out a clinical study, involving neurostimulation on six patients with a treatment-resistant depressive episode. The trial consisted of a 3-week accelerated iTBS treatment, delivered to the left dorsolateral pre-frontal cortex. Clinical evaluation scales (Hamilton Rating Scale for Depression, Montgomery-Åsberg Depression Rating Scale, and Young Mania Rating Scale) were administered at baseline, after 2 weeks, and at the end of the stimulation cycle. Pharmacotherapy was maintained unchanged during iTBS treatment. Patients gave their informed consent both for the protocol and for the publication. Results: The treatment was well-tolerated. Depressive symptoms only slightly improved; however, patients' binge episodes remitted completely, which was a serendipitous finding. BED symptomatology complete remission lasted up to 12 weeks follow-up. Discussion: This is the first study regarding iTBS use in BED in comorbidity with BD-II. Further research is still needed to assess the efficacy of this technique in BED treatment.

Abstract
Aim: Individuals with eating disorders (EDs) may present with impulse control disorders (ICDs) and behavioral addictions (BAs), which may result in additional suffering and treatment resistance. However, the prevalence of ICDs and BAs in EDs has not been systematically examined. Therefore, this systematic review and meta-analysis aimed to assess the prevalence of ICDs and BAs in ED samples. Methods: A comprehensive electronic database search of the peer-reviewed literature was conducted in the following online databases: MEDLINE, PsycINFO, Embase, and CINAHL from their inception to May 2021. We restricted review eligibility to research studies reporting prevalence for ICDs or BAs in individuals with diagnosed EDs. The outcome for this review was the prevalence of ICDs or BAs in individuals with EDs. A series of random-effects meta-analyses were performed on eligible studies to estimate the pooled proportions and 95% confidence intervals (CIs). Results: Thirty-five studies met the inclusion criteria, including a total of 9,646 individuals identified as having an ED, 18 of these studies specifically examined ICDs/BAs in AN, BN, and BED. Random-effects pooled estimates demonstrated that the comorbid prevalence of any ICD was 22%. The prevalence of comorbid pathological/compulsive buying was highest (19%), followed by kleptomania (18%), pathological internet use (12%), intermittent explosive disorder (4%), trichotillomania (3%), and gambling disorder (2%). In addition, the prevalence of stealing/shoplifting behaviors was 30% in those with EDs. Conclusion: This is the first meta-analysis on the comorbid prevalence of EDs and ICDs/BAs. We found a moderate prevalence for these comorbid conditions, with approximately one out of five individuals with an ED also displaying a comorbid ICD/BA. Although causal inferences cannot be drawn, the numbers strongly suggest that clinical screening/monitoring of ICDs/BAs should be part of the clinical routine in cohorts with EDs. ED settings need either the capacity to manage these disorders or adequate access to relevant services. Further investigations are needed to reveal common underlying pathomechanisms.

Abstract
Background: Adolescent eating disorder day programmes (DP), or partial hospitalization programs, are becoming increasingly widespread worldwide. They typically function as an alternative to inpatient care and/or a step up or down in treatment intensity. There has been an increase in the number of publications within the last 5 years investigating DP outcomes. While there are now numerous programmes operating internationally, there is large variability in the content, structure and theoretical underpinnings of each programme. This makes it difficult to compare programme outcomes, and the impact the therapeutic model may have. Aims: To review existing literature on adolescent eating disorder DP treatment models and outcomes. Methods: A systematic scoping review was conducted. Four databases (PsychInfo, EMBASE, Medline, CENTRAL) were searched for relevant peer-reviewed journal articles and book chapters investigating adolescent eating disorder DPs that function as alternatives to inpatient treatment. No restrictions on study methodology were imposed. Studies were first mapped by location, study characteristics and day programme treatment characteristics, then narratively synthesized. Results: Forty nine studies were included in this review. All used a quantitative methodology. One study also included qualitative methods. The majority of studies included describe DPs in the USA (69%). Seventy-six percent of the studies described DPs that operate 5-days per week and most (57%) either only admit or only report on outcomes for restrictive eating disorders. Two-thirds (69%) reported on DPs that had a family focused treatment model, the remainder had a more integrated treatment model informed mostly by individual psychotherapeutic models. Generally, DP treatment is associated with weight gain and improvements in eating disorder and comorbid psychopathology. The studies that include follow-up data (27%) reveal improvements are usually maintained from 3 months to 2 years post-treatment. Early weight gain, early psychological change and early therapeutic alliance are associated with improved end of treatment outcomes. Findings regarding other potential predictors of outcome are mixed. Conclusions: Current evidence suggests day programmes are an effective alternative to inpatient treatment that lead to sustained improvements. DPs tend to either be young-person-only with a family-focused treatment model or all age with a more integrative model. Controlled, empirical investigations into the impact of the therapeutic model on outcomes are needed, as are investigations into treatment mechanisms and the individual and parent experience of day programme treatment.

Front Psychiatry 2021; 12:777529.

Abstract
Background: Eating disorders (ED) are a diagnostic category that includes several nosological units such as anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED). This category most often concerns women, while the peak incidence falls on the reproductive age. Therefore the issue of ED during pregnancy is an interesting topic. Due to the creation of unrealistic ideal of "desired," slim figure both by the mass media and social media even during and right after gestation, more and more pregnant women introduce behaviours aimed at maintaining the "perfect" appearance. However in some cases it may have serious consequences for the health of both mother and child leading to the creation of the term "pregorexia" by the media to describe this issue. Aim: The aim of this paper was to conduct a systematic review of the literature dealing with eating disorders in pregnant women, with particular emphasis on pregorexia. Method: A systematic review of literature published within the last 5 years (2016-2021) in English or Polish and available through MEDLINE / PubMed, Google Scholar and Cochrane Library databases was conducted based on the previously assumed inclusion and exclusion criteria. Results: Initially, 634 publications were obtained during the review, of which 55 papers were selected in the course of the title analysis. After further evaluation of abstracts, 28 papers were qualified for full text analysis. Ultimately, 10 papers were selected for the final analysis. Conclusions: The issue of ED in pregnant women is a broad topic covering a heterogeneous group of women-both those with a previous history and those with the onset during pregnancy. The occurrence of ED symptoms during this period is associated with a high likelihood of negative consequences for both the mother and the child. The course of pregnancies and deliveries in these patients is more complicated. Therefore, it seems reasonable to develop a multidisciplinary screening strategy and standards of management and supervision over this group of patients.

Abstract
Background: Anorexia nervosa (AN) is a life-threatening illness with poor treatment outcomes. Although transcranial direct current stimulation (tDCS) is a promising non-invasive brain stimulation method, its effect in patients with AN remains unclear. Objective: This study investigated changes in maladaptive eating behavior, body mass index (BMI), and depression after 10 sessions of anodal tDCS over the left dorsolateral prefrontal cortex (DLPFC). Methods: In this double-blind, randomized controlled trial, 43 inpatients with AN were divided to receive either active (n = 22) or sham (n = 21) tDCS over the left DLPFC (anode F3/cathode Fp2, 2 mA for 30 min). All patients filled the Eating Disorder Examination Questionnaire (EDE-Q) and Zung Self-Rating Depression Scale (ZUNG), and their BMI was measured. These values were obtained repeatedly in four stages: (1) before tDCS treatment, (2) after tDCS treatment, (3) in the follow-up after 2 weeks, and (4) in the follow-up after 4 weeks. Results: Primary outcomes (EDE-Q) based on the ANOVA results do not show any between-group differences either after the active part of the study or in the follow-up. Secondary analysis reveals a reduction in some items of EDE-Q. Compared with sham tDCS, active tDCS significantly improved self-evaluation based on body shape (p < 0.05) and significantly decreased the need of excessive control over calorie intake (p < 0.05) in the 4-week follow-up. However, the results do not survive multiple comparison correction. In both sham and active groups, the BMI values improved, albeit not significantly. Conclusion: We did not observe a significant effect of tDCS over the left DLPFC on complex psychopathology and weight recovery in patients with AN. tDCS reduced the need to follow specific dietary rules and improved body image evaluation in patients with AN. Tests with a larger sample and different positions of electrodes are needed. Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT03273205.

[PMID: 34335330 PMCID: PMC8319499 DOI: 10.3389/fpsyt.2021.682952] [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: 03/19/2021] [Accepted: 06/24/2021] [Indexed: 11/13/2022] Open
Abstract
Background: The body mass index is a key predictor of treatment outcome in patients with anorexia nervosa. In adolescents, higher premorbid BMI is a strong predictor of a favorable treatment outcome. It is unclear whether this relationship holds true for adults with anorexia nervosa. Here, we examine adult patients with AN and investigate the lowest and highest lifetime BMI and weight suppression as predisposing factors for treatment outcome. Methods: We included 107 patients aged 17-56 with anorexia nervosa and tracked their BMI from admission to inpatient treatment, through discharge, to follow-up at 1-6 years. Illness history, including lowest and highest lifetime BMI were assessed prior to admission. We used multiple linear regression models with minimal or maximal lifetime BMI or weight suppression at admission as independent variables to predict BMI at admission, discharge and follow-up, while controlling for patients' age, sex, and duration of illness. Results: Low minimal BMI had a negative influence on the weight at admission, which in turn resulted in a lower BMI at discharge. Higher maximal BMI had a substantial positive influence on BMI at discharge and follow-up. Weight suppression was highly correlated with maximal BMI and showed similar effects to maximal BMI. Conclusion: Our findings strongly support a relationship between low minimal lifetime BMI and lower BMI at admission, and between higher maximal lifetime BMI or weight suppression and a positive treatment outcome, even years after discharge. Overall, maximal BMI emerged as the most important factor in predicting the weight course in adults with AN.

Abstract
Background: Eating disorders, including anorexia nervosa (AN) and bulimia nervosa (BN), are complex mental disorders. A better understanding of the burden of eating disorders is essential for improving their management. Information about the burden of eating disorders at the national level in China remains unclear. Methods: This is a systematic analysis of the Global Burden of Disease Study (GBD) 2019. The sex- and age-specific prevalence, incidence, and disability-adjusted life years (DALYs) of eating disorders in China were estimated by systematically reviewing all available epidemiological data and inputting these data into a Bayesian meta-regression tool (DisMod-MR 2.0). Trends in the age-standardized prevalence, incidence, and DALYs due to AN and BN were assessed from 1990 to 2019. Results: The age-standardized incidence rate (ASIR), prevalence rate (ASPR), and DALY rate per 100,000 population were estimated to be 13.22 (95% UI, 9.35-18.23), 38.08 (95% UI: 26.37-55.73), and 8.38 (95% UI, 4.87-13.35) for AN and 130.05 (95% UI, 84.02-187.13), 75.21 (95% UI, 48.52-105.97), and 16.16 (95% UI, 9.23-25.40) for BN, respectively, in 2019. The prevalence, incidence, and DALY rate of AN peaked at 15-19 years old. The prevalence and DALY rate of BN peaked at 30-34 years old. Females had a higher burden of AN and a lower burden of BN than males. The ASIR, ASPR, and DALY significantly increased by 1.3% (95% CI: 1.3-1.4%), 1.6% (95% CI, 1.5-1.6%), and 1.6% (95% CI, 1.5-1.7%) for AN and 1.4% (95% CI: 1.4-1.4%), 2.0% (95% CI, 2.0-2.1%), and 2.0% (95% CI, 2.0-2.1%) for BN, respectively, from 1990 to 2019 in China. In addition, the increments in all the age-standardized measures of BN were higher in males than in females. Conclusions: The burden of eating disorders in China showed unexpected patterns that varied by sex and age, with increasing trends of AN and BN from 1990 to 2019. More attention should be given to improving the burden of BN in males in China.

Abstract
OBJECTIVE Lifetime prevalence rates in Te Rau Hinengaro (The New Zealand Mental Health Survey) suggest eating disorders are at least as common in the Māori population as the non-Māori population, yet little is known at a population level about those accessing specialist mental health treatment for eating disorders in New Zealand. The aim of this study was to describe the population undergoing specialist mental health treatment for eating disorders and compare Māori and non-Māori clinical characteristics and service use. METHOD This study uses the Programme for the Integration of Mental Health Data data set, managed by the New Zealand Ministry of Health to describe the characteristics of people with eating disorders and their use of specialist mental health services from 2009 to 2016. RESULTS There were 3,835 individuals with a diagnosed eating disorder who had contact with specialist mental health services in this time period, 7% of whom were Māori. Within the cohort, Māori had a higher prevalence for a bulimia nervosa diagnosis, fewer diagnosed with anorexia nervosa, and a higher prevalence of other psychiatric comorbidity than non-Māori. DISCUSSION There is discrepancy between the proportion of service users accessing specialist mental health services who are Māori and the assessed crude prevalence of eating disorders for Māori in national estimates. Once Māori are in specialist services; however, their use of services is comparable to non-Māori. Further research is needed to highlight the experiences of those Māori with eating disorders and address barriers to accessing services for Māori with eating disorders.

Abstract
INTRODUCTION Anorexia nervosa (AN) is a serious and persistent eating disorder, characterized by severe dietary restriction and weight loss, with a third of patients developing a severe-enduring form. The factors contributing to this progression are poorly understood, although there is evidence for impairments in neural structures such as the hippocampus, an area particularly affected by malnutrition and chronic stress. AREAS COVERED This study aimed to map the evidence for alterations in hippocampal volume, function, and related molecular activity in anorexia nervosa. PubMed, PsycINFO, and Web of Science were searched for studies related to hippocampal function and integrity using a range of methodologies, such as neuropsychological paradigms, structural and functional magnetic resonance imaging, and analysis of blood components. EXPERT OPINION Thirty-nine studies were included in this review. The majority were neuroimaging studies, which found hippocampus-specific volumetric and functional impairments. Neuropsychological studies showed evidence for a specific memory and learning impairments. There was some evidence for molecular abnormalities (e.g. cortisol), although these were few studies. Taken together, our review suggests that the hippocampus might be a particular region of interest when considering neurobiological approaches to understanding AN. These findings warrant further investigation and may lead to novel treatment approaches.

Abstract
FINDINGS Although several individual psychotherapies for adults with eating disorders are empirically supported, with family-based treatment (FBT) being the leading recommended empiric treatment in adolescents, patients with eating disorders are still difficult to treat, and outcomes are often poor. In some countries, the clinical services for adolescents and adults are separate, and it is common for patients to receive treatments that differ in terms of both theory and content when they are switched from adolescent to adult services. Changes in the nature of treatment also often occur when patients move from less intensive types of care to more intensive treatment, and vice versa. These transitions may create a discontinuity in the care pathway and disorient patients and their significant others about the strategies and procedures used for addressing eating problems. However, the observation that younger and older patients essentially share the same eating-disorder psychopathology has led to evidence-based enhanced cognitive-behavioral therapy (CBT-E) being adapted for use in adolescents. Originally an evidence-based treatment for adults with eating disorders, CBT-E has yielded promising results in trials in cohorts of adolescent outpatients and inpatients, and is recommended as an alternative to FBT in adolescent patients. IMPLICATIONS With a unified treatment such as CBT-E, several issues that plague conventional eating-disorder services could be partially overcome, as patients can move seamlessly from adolescence to adulthood and through different levels of care, with no change in the nature of the treatment itself. Future randomized, controlled trials should compare FBT to CBT-E to better clarify the specific therapeutic needs of subgroups of adolescents and adult patients with eating disorders.

Abstract
OBJECTIVE Perceived parental influence on diet in early adolescence in the context of the parental relationship had previously not been studied in a clinical sample. The aim of this study was to investigate a possible association between eating disorders and characteristics of the relationship with parents and the parental feeding practices in early adolescence. METHODS 21 female adolescents and young adults with an eating disorder (ED)-bulimia nervosa or anorexia nervosa-and 22 females without eating disorder (healthy control; HC), aged between 16 and 26, were assessed via self-report questionnaires for problematic eating behaviour, relationship with parents, perceptions of parent's feeding practices at the age of 10-13 years and personality. Statistical evaluation was performed by means of group comparisons, effect sizes, regression analyses and mediator analyses. RESULTS Adolescent and young adult females with ED reported more fears/overprotection and rejection/neglect by their mothers and less self-responsibility in terms of eating behaviour during adolescence than did the HC. The relationship with the fathers did not differ significantly. Females who perceived more cohesion, rejection/neglect and fears/overprotection by the mother were more likely to suffer from an ED. Rejection/neglect by both parents were associated with less self-acceptance of the young females with even stronger effect sizes for the fathers than the mothers. Harm prevention in the young females was a partial mediator between fears/overprotection and the drive for thinness. CONCLUSIONS The parental relationship is partly reflected in the self-acceptance and self-responsibility in eating of the adolescent and young females, both of them are particularly affected in EDs. Stressors in the parent-child relationship should be targeted in treatment of eating disorders. Nutritional counselling for parents might be useful in early adolescence.

Abstract
The objective of this study was to investigate the clinical efficacy of parenteral nutrition (PN) as supplemental feeding for patients with anorexia nervosa (AN). This study was conducted by reviewing the medical records of patients with AN who were hospitalized at a non-specialized ward. A total of 129 patients with AN were recruited, consisting of 67 patients received PN with oral refeeding and 62 patients received oral refeeding alone. We compared the weight gain at discharge and after discharge between the groups. As a result, at admission, the patients given supplementary PN had lower body mass indices and lower caloric intake than the patients without PN. The mean duration of PN was 8.5 days, which amounted to about a third of the average hospital stay with no difference between the groups. Both groups had similar weight gains during hospitalization, but the patients with PN had higher weight gains than the patients without PN at one and three months after discharge. In conclusion, the results suggest that supplementary PN in the early stage of refeeding might initiate weight gain in AN when nasogastric tube feeding is not possible. Randomized controlled trials are needed to be further tested of PN in treatment of AN.

Abstract
PURPOSE OF REVIEW To review the recent literature on the burden of eating disorders in terms of mortality, disability, quality of life, economic cost, and family burden, compared with people without an eating disorder. RECENT FINDINGS Estimates are that yearly over 3.3 million healthy life years worldwide are lost because of eating disorders. In contrast to other mental disorders, in anorexia nervosa and bulimia nervosa years lived with disability (YLDs) have increased. Despite treatment advances, mortality rates of anorexia nervosa and bulimia nervosa remain very high: those who have received inpatient treatment for anorexia nervosa still have a more than five times increased mortality risk. Mortality risks for bulimia nervosa, and for anorexia nervosa treated outside the hospital, are lower but still about twice those of controls. In people with an eating disorder, quality of life is reduced, yearly healthcare costs are 48% higher than in the general population, the presence of mental health comorbidity is associated with 48% lower yearly earnings, the number of offspring is reduced, and risks for adverse pregnancy and neonatal outcomes are increased. SUMMARY People with a current or former eating disorder are at risk of increased mortality, high YLD rates, a reduced quality of life, increased costs, and problems with childbearing.

Abstract
PURPOSE OF REVIEW Eating disorders are associated with numerous medical complications. The aim of this study was to review recent progress in improving the medical management of patients with eating disorders. RECENT FINDINGS With close medical monitoring and electrolyte supplementation, accelerated refeeding protocols improve weight restoration without increasing the risk of refeeding syndrome. Olanzapine improves weight restoration better than placebo, without leading to adverse metabolic effects seen in individuals not in starvation. Alterations of the gut microbiome in anorexia nervosa have been demonstrated, but their clinical relevance remains unclear. SUMMARY Medical complications of eating disorders may facilitate the first contact with health professionals and treatment initiation. Medical complications of anorexia nervosa generally occur due to starvation, malnutrition and their associated physiological effects, whereas medical complications of bulimia nervosa are generally due to purging behaviors. Most medical complications in patients with binge eating disorder are secondary to obesity. Most medical complications of eating disorders can be effectively treated with nutritional management, weight normalization and the termination of purging behaviors. In summary, eating disorders are associated with many medical complications that have to be carefully assessed and managed as early as possible to improve long-term outcomes.

Abstract
PURPOSE OF REVIEW Studies indicate that environmental factors, acting at various moments throughout the life cycle, can result in epigenetically mediated alterations in gene expression. In this article, we review recent findings on the role of epigenetic factors in eating disorders, address methodological issues that need to be considered when interpreting research findings, and comment on possible clinical applications. RECENT FINDINGS Evidence suggests that eating disorders implicate alterations of methylation in genes involved in the mental status, metabolism, anthropometric features and immunity. Furthermore, some research in individuals with anorexia nervosa suggests the presence of reversible, malnutrition-induced epigenetic alterations that 'reset' as patients recover. SUMMARY Epigenetic studies in the eating disorders corroborate the idea that eating disorder cause is multifactorial, and identify markers that could help inform our understanding of illness staging and subtyping that may explain the commonly progressive course of these disorders, and that may provide insights towards the development of novel interventions. Already, there is evidence to suggest that, in people with eating disorders, epigenetically informed interventions help reduce stigma and shame, and increase self-acceptance and hopes of recovery. Although findings are intriguing, further research is required as, to date, studies apply modest sample sizes and disparate methodologies.

Abstract
INTRODUCTION Previous studies have suggested that maternal diabetes may have programming effect on fetal brain development. However, little is known about the association between maternal diabetes and neurodevelopmental disorders in offspring that mainly manifest in infancy or early childhood. We aimed to examine the association between maternal diabetes before or during pregnancy and feeding and eating disorders (FED) in offspring. RESEARCH DESIGN AND METHODS This population-based cohort study included 1 193 891 singletons born in Denmark during 1996-2015. These children were followed from birth until the onset of FED, the sixth birthday, death, emigration, or 31 December 2016, whichever came first. Relative risk of FED was estimated by HRs using Cox proportional hazards model. RESULTS A total of 40 867 (3.4%) children were born to mothers with diabetes (20 887 with pregestational diabetes and 19 980 with gestational diabetes). The incidence rates of FED were 6.8, 4.6 and 2.9 per 10 000 person-years among children of mothers with pregestational diabetes, gestational diabetes and no diabetes, respectively. Offspring of mothers with diabetes had a 64% increased risk of FED (HR 1.64; 95% CI 1.36 to 1.99; p<0.001). The HR for maternal pregestational diabetes and gestational diabetes was 2.01 (95% CI 1.59 to 2.56; p<0.001) and 1.28 (95% CI 0.95 to 1.72; p=0.097), respectively. The increased risk was more pronounced among offspring of mothers with diabetic complications (HR 2.97; 95% CI 1.54 to 5.72; p=0.001). CONCLUSIONS Maternal diabetes was associated with an increased risk of FED in offspring in infancy and early childhood. Our findings can inform clinical decisions for better management of maternal diabetes, in particular before pregnancy, which can reduce early neurodevelopmental problems in the offspring.

Abstract
OBJECTIVE This study assessed longer-term outcomes from a randomised controlled feasibility trial of 20 sessions of real versus sham high-frequency repetitive transcranial magnetic stimulation (rTMS) to the left dorsolateral prefrontal cortex in adults with severe, enduring anorexia nervosa (SE-AN). METHODS Thirty participants who completed the original study protocol were invited to take part in an open follow-up (18-months post-randomisation), assessing body mass index (BMI), eating disorder (ED) symptoms and other psychopathology. RESULTS Twenty-four participants (12 each originally allocated to real/sham) completed the 18-month follow-up. Ten of 12 participants who originally received sham treatment had real rTMS at some stage during the follow-up. A medium between-group effect size was seen for BMI change from baseline to 18-months, favouring those originally allocated to real rTMS. In this group at 18-months, five participants were weight recovered (BMI ≥18.5 kg/m2 ), compared with one participant in the original sham group. Both groups showed further improvement in ED symptoms during the follow-up. Effects on mood were largely maintained at follow-up, with catch-up effects in the original sham group. CONCLUSIONS Findings suggest that rTMS treatment effects on mood are durable and that BMI and ED symptom improvements need time to emerge. Large-scale trials are needed.

Abstract
The management of eating disorders (EDs) is still difficult and few treatments are effective. Recently, several studies have described the important contribution of non-invasive brain stimulation (repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and electroconvulsive therapy) and invasive brain stimulation (deep brain stimulation and vagal nerve stimulation) for ED management. This review summarizes the available evidence supporting the use of brain stimulation in ED. All published studies on brain stimulation in ED as well as ongoing trials registered at clinicaltrials.gov were examined. Articles on neuromodulation research and perspective articles were also included. This analysis indicates that brain stimulation in EDs is still in its infancy. Literature data consist mainly of case reports, cases series, open studies, and only a few randomized controlled trials. Consequently, the evidence supporting the use of brain stimulation in EDs remains weak. Finally, this review discusses future directions in this research domain (e.g., sites of modulation, how to enhance neuromodulation efficacy, personalized protocols).

Abstract
The current study used receiver operating characteristic (ROC) curve analysis to examine the accuracy of somatotype components in correctly classifying disordered eating attitudes (DEA) in female dance students. Participants were a sample of 81 female dancers distributed in two groups: beginner training (BT; age (mean ± SD) = 10.09 ± 1.2 years, n = 32) and advanced training (AT; age = 15.37 ± 2.1 years, n = 49). For evaluation of DEA, the Eating Attitudes Test- 26 (EAT-26) questionnaire was used. We defined an EAT-26 score ≥20 as positive for DEA. Somatotype components were calculated using the Heath-Carter anthropometric method. The risk of presenting DEA was 28.1% (n = 9) in the BT group and 6.1% (n = 3) in the AT group. In the BT group, mesomorphy demonstrated moderate-high accuracy in predicting DEA (area under the curve (AUC) = 0.82, 95% confidence interval (CI): 0.64-0.93). The optimal cut-off of 6.34 yielded a sensitivity of 0.77 and a specificity of 0.95. Ectomorphy showed moderate accuracy in predicting DEA (AUC = 0.768, 95% CI: 0.58-0.89). The optimal cut-off of 2.41 yielded a sensitivity of 0.78 and a specificity of 0.78. In the AT group, none of the components demonstrated accuracy in predicting DEA. Somatotype components were good predictors of disordered eating attitudes in the younger dance student group (beginner training). Further research is needed to identify the determinants of these differences between the two groups.

Abstract
Recent work using naturalistic, repeated, ambulatory assessment approaches have uncovered a range of within-person mood- and body image-related dynamics (such as fluctuation of mood and body dissatisfaction) that can prospectively predict eating disorder behaviors (e.g., a binge episode following an increase in negative mood). The prognostic significance of these state-based dynamics for predicting trait-level eating disorder severity, however, remains largely unexplored. The present study uses within-person relationships among state levels of negative mood, body image, and dieting as predictors of baseline, trait-level eating pathology, captured prior to a period of state-based data capture. Two-hundred and sixty women from the general population completed baseline measures of trait eating pathology and demographics, followed by a 7 to 10-day ecological momentary assessment phase comprising items measuring state body dissatisfaction, negative mood, upward appearance comparisons, and dietary restraint administered 6 times daily. Regression-based analyses showed that, in combination, state-based dynamics accounted for 34-43% variance explained in trait eating pathology, contingent on eating disorder symptom severity. Present findings highlight the viability of within-person, state-based dynamics as predictors of baseline trait-level disordered eating severity. Longitudinal testing is needed to determine whether these dynamics account for changes in disordered eating over time.

Abstract
Background: Adolescents' eating disorders have been explored through various conceptual and empirical models. Only recently, scientific literature in this area has more specifically investigated the role of relationships, with particular attention to family functioning. Objective: This paper reviews family relationships aspects of eating disorders in adolescence. Methods: A narrative literature review of relational issues in adolescents' eating disorders was performed. Results: Empirical evidence of family relationships in adolescents' eating disorders confirms the relevance of relational aspects in the development and maintenance of the pathology. In particular, the contribution of the relational-systemic approach is wide, suggesting the need to refer to the family context for a better understanding of adolescents' sufferance. Additionally, the empirical contributions from the conceptual model of Developmental Psychopathology, highlighting the importance of risk and protection factors in family relationships, provides knowledge about the phenomenon of adolescents' eating disorders in terms of complexity. Conclusions: An integrated relational model aimed to explore adolescents' eating disorders is worthy of investigation to accomplish specific program of intervention.

Abstract
PURPOSE OF REVIEW The current report aims to summarize recent advances about the relationship between non-suicidal self-injury (NSSI) and eating disordered (ED) behaviors and highlights meaningful directions for future research. RECENT FINDINGS While there is solid evidence indicating a robust cross-sectional association between NSSI and ED behaviors, emerging evidence suggests that the temporal relationship between these behaviors may be bidirectional. Shared functions and risk factors may explain why these behaviors often co-develop. At the same time, little is still known about the psychosocial consequences of comorbid NSSI and ED engagement, and there is a lack of intervention studies that target these behaviors simultaneously. It is well-established that NSSI and ED behaviors frequently co-occur. The field should now turn to longitudinal designs to advance our understanding of the longer-term developmental and the shorter-term momentary relationship of these behaviors in daily life. Providing insight into these areas will help guide the deployment of evidence-based interventions that match the needs of clients who report comorbid NSSI and ED behaviors.
