Background: We studied the effect of the Covid-19 pandemic on child eating disorder hospitalizations in Quebec, Canada. Quebec had one of the strictest lockdown measures targeting young people in North America., Methods: We analyzed eating disorder hospitalizations in children aged 10-19 years before and during the pandemic. We used interrupted time series regression to assess trends in the monthly number of hospitalizations for anorexia nervosa, bulimia nervosa, and other eating disorders before the pandemic (April 2006 to February 2020), and during the first (March to August 2020) and second waves (September 2020 to March 2021). We determined the types of eating disorders requiring hospital treatment and identified the age, sex and socioeconomic subgroups that were most affected., Results: Hospitalization rates for eating disorders increased during the first (6.5 per 10,000) and second waves (12.8 per 10,000) compared with the period before the pandemic (5.8 per 10,000). The increase occurred for anorexia nervosa as well as other types of eating disorders. The number of girls and boys aged 10-14 years admitted for eating disorders increased during wave 1. Wave 2 triggered an increase in eating disorder admissions among girls aged 15-19 years. Hospitalization rates increased earlier for advantaged than disadvantaged youth., Conclusions: The Covid-19 pandemic affected hospitalizations for anorexia nervosa as well as other eating disorders, beginning with girls aged 10-14 years during wave 1, followed by girls aged 15-19 years during wave 2. Boys aged 10-14 years were also affected, as well as both advantaged and disadvantaged youth., (© 2023 The Authors.

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., (© 2021 Eating Disorders Association and John Wiley & Sons Ltd.)

Eating disorder (ED) variants characterized by "binge-eating/purging" symptoms differ from "restricting-only" variants along diverse clinical dimensions, but few studies have compared people with these different eating-disorder phenotypes on measures of neurocognitive function and brain activation. We tested the performances of 19 women with "restricting-only" eating syndromes and 27 with "binge-eating/purging" variants on a modified n-back task, and used functional magnetic resonance imaging (fMRI) to examine task-induced brain activations in frontal regions of interest. When compared with "binge-eating/purging" participants, "restricting-only" participants showed superior performance. Furthermore, in an intermediate-demand condition, "binge-eating/purging" participants showed significantly less event-related activation than did "restricting-only" participants in a right posterior prefrontal region spanning Brodmann areas 6-8-a region that has been linked to planning of motor responses, working memory for sequential information, and management of uncertainty. Our findings suggest that working memory is poorer in eating-disordered individuals with binge-eating/purging behaviors than in those who solely restrict food intake, and that observed performance differences coincide with interpretable group-based activation differences in a frontal region thought to subserve planning and decision making., (Copyright © 2015 Elsevier Ireland Ltd.

Introduction: Evidence associates Bulimia Nervosa (BN) with altered functioning of the hypothalamic-pituitary-adrenal (HPA) axis, but the clinical implications of such alterations need to be better understood. We contrasted cortisol responses to the dexamethasone suppression test (DST) in bulimic and non-eating disordered women and examined relationships among DST cortisol responses, eating symptoms and co-morbid disturbances., Method: Sixty women with Bulimia Spectrum (BS) Disorders (either BN or normal weight Eating Disorder NOS with regular binge eating or purging) and 54 non-eating disordered women of similar age and body mass index participated in a 0.5 mg DST, and completed interviews and questionnaires assessing eating symptoms and co-morbid psychopathology., Results: Compared with the normal-eater group, the BS women demonstrated significantly less DST suppression. Among BS women, DST non-suppression was associated with more severe depression, anxiety and eating preoccupations., Conclusions: Our findings show BS women to show less DST suppression compared to normal eater women, and results link extent of non-suppression, in BS individuals, to severity of depression, anxiety and eating preoccupations., (Copyright © 2012 Elsevier Inc.

Objective: To determine the association between adolescent hospitalization for suicide attempts and the subsequent risk of eating disorder hospitalization. Method: This was a cohort study of 162,398 adolescent girls in Quebec, Canada, including 7741 with suicide attempts before 20 years of age, matched to 154,657 adolescents with no attempt between 1989 and 2019. The main exposure measure was suicide attempt hospitalization. The main outcome measure was hospitalization for an eating disorder up to 31 years later, including anorexia nervosa, bulimia nervosa, and other eating disorders. We used adjusted Cox regression models to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association between adolescent suicide attempts and eating disorder hospitalization. Results: Adolescent girls admitted for a suicide attempt had 5.55 times the risk of eating disorder hospitalization over time (95% CI 3.74–8.23), compared with matched controls. Suicide attempt was associated with anorexia nervosa (HR 3.57, 95% CI 1.78–7.17) and bulimia nervosa and other eating disorders (HR 8.55, 95% CI 5.48–13.32). Associations were pronounced in girls with repeated suicide attempts. Girls who attempted suicide through self‐poisoning had an elevated risk of anorexia nervosa, whereas girls who used violent methods such as cutting or piercing had a greater risk of bulimia nervosa and other eating disorders. Suicide attempt was strongly associated with eating disorder hospitalization in the year following the attempt, but associations persisted throughout follow‐up. Discussion: Suicide attempt admission is associated with the long‐term risk of eating disorder hospitalization in adolescent girls. Public Significance: This study of adolescent girls suggests that suicide attempt admission is associated with the long‐term risk of hospitalization for eating disorders. The risk is greatest in the year after the attempt, but persists over time. Adolescents who present with a suicide attempt may benefit from screening for eating disorders and long‐term follow‐up to help prevent the exacerbation or development of eating disorders.
