Associations Between Weight Discrimination, Eating-Disorder-Related Psychiatric Impairment, and Eating-Disorder Treatment Interest Across the Weight Spectrum.

OBJECTIVE: Only approximately 20% of college students with an eating disorder (ED) seek treatment. One barrier to seeking treatment is weight discrimination. Past research demonstrates that experiencing weight discrimination is associated with increased ED risk and decreased in-person treatment engagement. Weight discrimination may be a particularly relevant treatment barrier for students who have a higher body weight given their higher likelihood of experiencing weight discrimination. METHODS: College students with a probable ED diagnosis (N = 372; Mage = 23.94; 73.12% women, 18.55% men, 6.18% another gender; 11.29% Asian, 4.57% Black, 12.63% Hispanic, 83.60% White, 4.84% Native American, and 0.54% another race) completed an online self-report survey that included the Clinical Impairment Assessment (CIA), Experience of Weight Discrimination (EWD) Scale, and a 0-100 scale to indicate interest in participating in virtual guided self-help ED treatment. RESULTS: Linear regression showed significant positive relationships between weight discrimination and ED-related psychiatric impairment and treatment interest. DISCUSSION: Elevations in CIA scores corroborate past literature that suggested that weight discrimination was positively related to ED psychopathology. Contrary to past research, college students who experienced weight discrimination had greater treatment interest. Students who experience weight discrimination may view virtual self-guided treatment as less weight-stigmatizing due to the "do-it-yourself" approach and no in-person interactions. Findings highlight the potential impacts of weight discrimination on acceptability of ED-related care. Future research is needed to identify ways to reduce weight discrimination and promote weight-inclusive practices in the medical system.

Examining associations between disordered eating and harmful substance use in a nationally representative sample of US veterans.

OBJECTIVE: The association between eating disorders (EDs) and harmful substance use (substance use that causes psychosocial impairment) is well recognized in the literature, and military veterans may be at heightened risk for both issues due to deployment-related stressors. However, little is known about which ED-related symptoms are associated with harmful substance use in veterans, and whether gender plays a differential role in this relationship. Our aims were to: (1) examine gender differences in ED-related symptoms; and (2) examine whether ED-related symptoms differentially predict harmful substance use in US veteran men and women who had recently separated from service. METHOD: This study was based on a nationally representative four-wave longitudinal sample of post-9/11 veterans (N = 835; 61.2% female). Longitudinal mixed modeling was used to test whether specific ED-related behaviors at baseline predicted harmful substance use at follow-ups. RESULTS: We replicated gendered patterns of ED-related symptoms observed in civilian populations, wherein men had higher weight-and-body-related concerns (including excessive exercise and muscle building) and negative attitude toward obesity, and women had higher bulimic and restricting symptoms. For women, alcohol, drug, and marijuana problems were predicted by higher bulimic symptoms, whereas for men, these problems were predicted by higher restricting symptoms. CONCLUSION: Gender played a differential role in the relationship between EDs and harmful substance use. Bulimic symptoms were the most robust predictor for harmful substance use among veteran women, whereas restricting was the most robust predictor for harmful substance use among veteran men. PUBLIC SIGNIFICANCE: The current study found that veteran women had higher bulimic symptoms (characterized by binge eating and purging) and restricting than veteran men. In women, bulimic symptoms predicted future harmful use of alcohol, marijuana, and other drugs. In contrast, veteran men had higher weight-and-body-related concerns (characterized by excessive exercise and muscle building) than veteran women. In men, restricting symptoms predicted future harmful use of alcohol, marijuana, and other drugs.

Understanding community provider practices in diagnosing and treating atypical anorexia nervosa: A mixed methods study.

OBJECTIVE: There is a lack of consensus in defining "significant weight loss" when diagnosing atypical anorexia nervosa (atypical AN) and no guidelines exist for setting target weight (TW). The current study aimed to identify community providers' practices related to the diagnosis of atypical AN and the determination of TW. A secondary aim was to evaluate whether professional discipline impacted "significant weight loss" definitions. METHOD: A variety of providers (N = 141; 96.4% female) completed an online survey pertaining to diagnostic and treatment practices with atypical AN. Descriptive statistics were computed to characterize provider-based practices and Fisher's exact tests were used to test for differences in diagnostic practices by professional discipline. Thematic analysis was used to examine open-ended questions. RESULTS: Most (63.97%) providers diagnosed atypical AN in the absence of any weight loss if other AN criteria were met, but doctoral-level psychologists and medical professionals were less likely to do so compared to nutritional or other mental health professionals. Most providers found weight gain was only sometimes necessary for atypical AN recovery. Qualitative responses revealed providers found atypical AN to be a stigmatizing label that was not taken seriously. Providers preferred to use an individualized approach focused on behaviors, rather than weight when diagnosing and treating atypical AN. DISCUSSION: Lack of diagnostic clarity and concrete treatment guidelines for atypical AN may result in substantial deviations from the DSM-5-TR criteria in real-world practice. Clinically useful diagnostic definitions for restrictive eating disorders and evidence-based treatment guidelines for TW and/or other relevant recovery metrics are needed. PUBLIC SIGNIFICANCE: The current study found variability in how community providers diagnose and determine target recovery weight for atypical anorexia nervosa (atypical AN). Many providers viewed the diagnosis of atypical AN as stigmatizing and preferred to focus on behaviors, rather than weight. This study underscores the importance of creating a clinically useful diagnostic definition and guidelines for recovery for atypical AN backed by empirical evidence that providers may implement in practice.
