Although treatment dropout is common among patients with eating disorders, very few studies have examined predictors of non‐completion in day treatment. We investigated various potential predictors of dropout from adult day treatment. Participants were 295 adult patients with a diagnosis of Anorexia Nervosa (restricting or binge‐eating/purging subtype), Bulimia Nervosa (BN), Other Specified Feeding or Eating Disorder, or Avoidant Restrictive Food Intake Disorder. Predictors included eating‐disorder characteristics, motivation at the commencement of treatment, Body Mass Index (BMI), time spent in treatment and personality dimensions. Logistic regression analyses showed that for patients with a BMI of less than 20 at the start of treatment, low BMI was a significant predictor of staff‐initiated termination due to not meeting weight gain goals. Furthermore, completing less than 6 weeks of treatment was associated with staff‐initiated termination. For the whole sample, those with higher changes in weight over the course of treatment were less likely to terminate prematurely. None of the other predictor variables yielded significant results. Results of the current study highlight characteristics of patients who are more likely not to complete day treatment and can help identify patients who may be at risk for not succeeding in multi‐diagnostic day treatment programs. Highlights: For patients attending day treatment, low BMI at the start of treatment was a significant predictor of staff‐initiated discharge in participants who entered the program with a BMI < 20For all patients, larger changes in BMI over the course of treatment predicted higher likelihood of completing treatmentResults can help identify which patients may be at risk for not succeeding in multi‐diagnostic day treatment programs and address this risk in the transition to a higher level of care from lower levels [ABSTRACT FROM AUTHOR]

Objective: Findings show virtual therapy (conducted using internet‐based videoconferencing techniques) to be a viable alternative to in‐person therapy for a variety of mental‐health problems. COVID‐19 social‐distancing imperatives required us to substitute virtual interventions for in‐person sessions routinely offered in our outpatient eating disorder (ED) program—and afforded us an opportunity to compare the two treatment formats for clinical efficacy. Methods: Using self‐report assessments, we compared outcomes in a historical sample of 49 adults with heterogeneous EDs (treated in‐person over 10–14 weeks in individual and group therapies) to those of 76 patients receiving comparable virtual treatments, at distance, during the COVID‐19 outbreak. Linear mixed models were used to study symptom changes over time and to test for differential effects of treatment modality. Results: Participants in both groups showed similar improvements on eating symptoms, levels of weight gain (in individuals in whom gain was indicated), and satisfaction with services. Discussion: Our results suggest that short‐term clinical outcomes with virtual and in‐person ED therapies are comparable, and point to potentials of virtual therapy for situations in which geographical distance or other barriers impede physical access to trained therapists or specialized treatments.

Objective: Identifying modifiable predictors of outcomes following treatment for eating disorders may help to tailor interventions to patients' individual needs, improve treatment efficacy, and develop new interventions. The goal of this meta‐analysis was to quantify the association between pretreatment motivation and posttreatment changes in eating disorder symptomology. Method: We reviewed 196 longitudinal studies reporting on change on indices of overall eating‐disorder symptomatology, weight gain, binge‐eating, vomiting, anxiety/depression, and treatment adherence. Meta‐analyses were performed using two complementary approaches: (a) combined probability analysis using the added Z's method; (b) effect size analyses. Using random‐effect models, effect sizes were pooled when there were at least three studies with the same type of statistical design and reporting statistics on the same outcome. Heterogeneity in study outcome was evaluated using Q and I2 statistics. Studies were reviewed qualitatively when the number of studies or reported data were insufficient to perform a meta‐analysis. Results: Forty‐two articles were included. Although samples and treatments differed substantially across studies, results across studies were remarkably consistent. Both combined‐probability and effect‐size analyses indicated positive effects of pretreatment motivation on improvement in general eating‐disorder symptoms (Cohen's r =.17), and an absence of effects on anxiety/depression symptoms. Remaining outcome indices were subject to selective reporting and/or small sample size bias. Discussion: Our findings underscore the importance of incorporating treatment engagement approaches in the treatment of eating disorders. Optimal reporting of study findings and improving study quality would improve future efforts to obtain an in‐depth understanding of the relationship between motivation and eating disorder symptoms.

Objective: People who are ill with anorexia nervosa (AN) show altered availability of key plasma nutrients. However, little is known about the patterning of alterations that occurs across diverse nutrients during active phases of illness or about the persistence of any such alterations following remission of illness. Method: We compared plasma levels of one‐carbon metabolism nutrients across women with active AN (AN‐Active: n = 53), in remission from AN (AN‐Remitted: n = 40), or who had no eating‐disorder history (NED: n = 36). We also tested associations between body mass index (BMI) changes and changes in pre‐ to posttreatment nutrient levels, and explored the association between nutrient levels, on the one hand, and BMI and eating symptoms, on the other. Choline, betaine, and methionine were analyzed using mass spectrometry. Folate and B12 were analyzed using the AccuBind® ELISA kit. Eating‐disorder symptoms were assessed by interview and self‐report. Results: Compared to NED individuals, AN‐Active individuals exhibited significantly elevated B12 and (less‐reliably) betaine. In AN‐Active individuals, lower BMI was associated with higher B12. Discussion The observed alterations run contrary to the intuition that plasma nutrient levels should be directly responsive to nutritional status and suggest, instead, the existence of compensatory adaptations to malnutrition in individuals with active AN. Further study is required to clarify mechanisms that underlie such effects. [ABSTRACT FROM AUTHOR]

DNA methylation allows for the environmental regulation of gene expression and is believed to link environmental stressors to psychiatric disorder phenotypes, such as anorexia nervosa (AN). The oxytocin receptor (OXTR) gene is epigenetically regulated, and studies have shown associations between OXTR and social behaviours in various samples, including women with AN. The present study examined differential levels of methylation at various CG sites of the OXTR gene in 69 women with active AN (AN‐Active), 21 in whom AN was in remission (AN‐Rem) and 35 with no eating disorder (NED). Within each group, we explored the correlation between methylation and measures of social behaviour such as insecure attachment and social avoidance. Hypermethylation of a number of CG sites was seen in AN‐Active participants as compared with AN‐Rem and NED participants. In the AN‐Rem sample, methylation at CG27501759 was significantly positively correlated with insecure attachment (r =.614, p =.003, permutation Q = 0.008) and social avoidance (r =.588, p =.005, permutation Q = 0.0184). Our results highlight differential methylation of the OXTR gene among women with AN, those in remission from AN, and those who never had AN and provide some evidence of associations between OXTR methylation and social behaviour in women remitted from AN.

ABSTRACT Objective Evidence associates anorexia nervosa (AN) with epigenetic alterations that could contribute to illness risk or entrenchment. We investigated the extent to which AN is associated with a distinct methylation profile compared to that seen in normal-eater women. Method Genome-wide methylation profiles, obtained using DNA from whole blood, were determined in 29 women currently ill with AN (10 with AN-restrictive type, 19 with AN-binge/purge type) and 15 normal-weight, normal-eater control women, using 450 K Illumina bead arrays. Results Regardless of type, AN patients showed higher and less-variable global methylation patterns than controls. False Discovery Rate corrected comparisons identified 14 probes that were hypermethylated in women with AN relative to levels obtained in normal-eater controls, representing genes thought to be associated with histone acetylation, RNA modification, cholesterol storage and lipid transport, and dopamine and glutamate signaling. Age of onset was significantly associated with differential methylation in gene pathways involved in development of the brain and spinal cord, while chronicity of illness was significantly linked to differential methylation in pathways involved with synaptogenesis, neurocognitive deficits, anxiety, altered social functioning, and bowel, kidney, liver and immune function. Discussion Although pre-existing differences cannot be ruled out, our findings are consistent with the idea of secondary alterations in methylation at genomic regions pertaining to social-emotional impairments and physical sequelae that are commonly seen in AN patients. Further investigation is needed to establish the clinical relevance of the affected genes in AN, and, importantly, reversibility of effects observed with nutritional rehabilitation and treatment. © 2015 Wiley Periodicals, Inc.
