Article Synopsis
  • The study investigated how different eating disorders (like anorexia and bulimia) vary in terms of symptoms related to anxiety, OCD, and depression upon treatment admission.
  • It included a sample of 3,730 adults and found that symptom patterns varied by disorder, with anorexia and avoidant/restrictive disorders showing more anxiety and OCD symptoms, while binge eating disorder had more depressive symptoms.
  • Overall, all patients, especially those with ARFID and binge eating disorder, showed significant improvement in their symptoms after treatment, although some groups had higher initial severity compared to others.

Background: Higher level of care (HLOC) treatment for eating disorders (EDs) is sometimes necessary, but research is lacking on whether HLOCs are actually more effective than less structured, lower levels of care. The purpose of the current study was to compare outcomes for patients with EDs at low weights who entered 24/7 care (inpatient and residential) to those entering non-24/7 care (partial hospitalization programming and intensive outpatient programming).

Methods: Participants were 1104 adults with body mass indices (BMI) between 14 and 17 receiving treatment for an ED at a large multisite treatment facility offering HLOCs between August 2019 and February 2024.

Background: Social risks (individual social and economic conditions) have been implicated as playing a major role in the opioid epidemic and may be more prevalent in the most medically vulnerable patients. However, the extent to which specific social risks and other patient factors are associated with opioid use among high-risk patients has not been comprehensively assessed.

Objective: To identify patient-reported and electronic health record (EHR)-derived demographic, social, behavioral/psychological, and clinical characteristics associated with opioid use in Veterans Affairs (VA) patients at high risk for hospitalization or death.

Background: Despite widespread use of higher levels of care in treating eating disorders in adolescents, research supporting the use of these treatments remains limited by small sample sizes and a predominant focus on anorexia nervosa. Further, existing data regarding predictors of outcome have yielded mixed findings. In the current study, we evaluated treatment outcomes and predictors of outcome among a large sample of adolescents with eating disorders presenting to inpatient, residential, partial hospitalization programs, and intensive outpatient programs across the United States.

Eating disorders (EDs) have historically been thought of as afflictions of younger women, but EDs do occur in midlife/older adults, and the incidence of EDs among older women may be increasing. The present study sought to examine outcomes for patients with anorexia nervosa needing to weight restore across four age groups: under 18, 18-25, 26-39, and 40+. Based on prior research, it was hypothesized that there would be no differences between the age groups in percent of expected body weight (%EBW) gained during treatment.

Objective: In a national cohort of Veterans, weight change was compared between participants in a US Department of Veterans Affairs (VA) behavioral weight management program (MOVE!) and matched non-participants, and between high-intensity and low-intensity participants.

Methods: Retrospective cohort study of Veterans with 1 + MOVE! visits in 2008-2017 were matched to MOVE! non-participants via sequential stratification. Percent weight change up to two years after MOVE! initiation of participants and non-participants was modeled using generalized additive mixed models, and 1-year weight change of high-intensity or low-intensity participants was also compared.

Objective: The co-occurrence of unhealthy alcohol use and opioid misuse is high and associated with increased rates of overdose, emergency health care utilization, and death. The current study examined whether receipt of an alcohol-related brief intervention is associated with reduced risk of negative downstream opioid-related outcomes.

Methods: This retrospective cohort study included all VISN-6 Veterans Affairs (VA) patients with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) screening results (N=492,748) from 2014 to 2019.

Objective: The purpose of this study was to examine the association between weight gain and eating disorder (ED) symptoms among adults receiving treatment for atypical anorexia nervosa (AAN), to determine whether those who had a higher percent of expected body weight (%EBW) at discharge exhibited lower ED symptoms than those who gained less weight, and to compare this group to a matched sample of patients with anorexia nervosa (AN).

Method: Participants were 96 adults receiving treatment at an ED treatment facility between December 2020 and May 2023. The Eating Disorder Examination-Questionnaire (EDE-Q) was completed at admission and discharge, and %EBW was obtained at admission and discharge.

Gaudiani et al. (2022) presented terminal anorexia nervosa (T-AN) as a potential new specifier to the anorexia nervosa (AN) diagnosis, with criteria including (a) AN diagnosis, (b) age > 30 years, (c) previously participated in high-quality care, and (d) the clear, consistent determination by a patient with decision-making capacity that additional treatment would be futile, knowing death will result. This study's purpose was to empirically examine a subgroup of participants with AN who met the first three criteria of T-AN-and a smaller subset who also met a proxy index of the fourth criterion involving death (TD-AN)-and compare them to an adult "not terminal" anorexia nervosa (NT-AN) group and to a "not terminal" subset 30 years of age or older (NTO-AN).

The COVID-19 pandemic has required a shift to telehealth services. However, not all patients are similarly satisfied with this shift, with some studies finding that midlife and older adults are less comfortable with telehealth. The current study examined patient satisfaction with a virtual intensive outpatient program (VIOP) for eating disorders (EDs) among 305 adults (ages 18-25, ages 26-39, and ages 40+), and compared adult satisfaction to satisfaction among children/adolescents ( = 33) receiving VIOP treatment between August 2020 and March 2022 from a large ED treatment facility.

Objective: The association between participation in a behavioral weight intervention and health expenditures has not been well characterized. We compared Veterans Affairs (VA) expenditures of individuals participating in MOVE!, a VA behavioral weight loss program, and matched comparators 2 years before and 2 years after MOVE! initiation.

Methods: Retrospective cohort study of Veterans who had one or more MOVE! visits in 2008-2017 who were matched contemporaneously to up to 3 comparators with overweight or obesity through sequential stratification on an array of patient characteristics, including sex.

Objective: Although eating disorders (EDs) occur throughout the lifespan, little research has been conducted with midlife/older adults, particularly those in higher levels of care (HLOC). The current study examined outcomes among 2009 patients with EDs receiving HLOC treatment at a large multisite facility between January 2020 and June 2022, across different age groups (ages <18, 18-25, 26-39 and ≥40). It was hypothesised that patients aged 40+ would exhibit less improvement on measures of ED psychopathology and depression than other age groups.

The Eating Disorder Examination-Questionnaire (EDE-Q) is a widely used self-report measure of eating pathology. Despite widespread use, investigations of its factor structure have proved inconclusive and rarely supported the "original" interpretation. The current study evaluates several proposed factor solutions of the EDE-Q using latent variable analysis in a sample of adult women with anorexia nervosa (AN).
