Global sleep disturbance is robustly linked with a subjective sense of loss-of-control over eating (LOC). Depressed mood has been proposed as a mechanism to explain the bi-directional relationship between sleep disturbance and LOC eating. The current study evaluated whether sleep disturbance indirectly affects LOC eating via depressed mood. Adults seeking treatment for a DSM-5 binge-spectrum eating disorder (e.g. bulimia nervosa, binge-eating disorder) were recruited (n = 79) and asked to complete self-report questionnaires assessing sleep disturbance and depression, and a semi-structured interview assessing LOC eating. Tests of indirect effects evaluated the effect of depressed mood on the association between global sleep disturbance and LOC frequency covarying for BMI and parent study. A significant indirect effect of depressed mood on the association between global sleep disturbance and frequency of LOC eating was identified (Est = 1.519, S.E. = 0.859, p = .033). The indirect effect of depressed mood on the association between sleep disturbance and LOC eating may indicate that depressed mood serves as a mechanistic link between sleep disturbance and LOC eating. The findings offer preliminary support for adjunctive treatments targeting both sleep disturbance and depressed mood for LOC eating. Future research should explore these pathways in a larger clinical sample.

Adolescents and young adults are at heightened risk for eating disorder (ED) and muscle dysmorphia (MD) symptoms; yet, these symptoms and their relationships to harmful behaviors may also vary by gender. Thus, this study examined: 1) the prevalence of attempts to lose, gain, or maintain the same weight across gender identities, 2) purposes of weight change attempts, and 3) relationships between weight change attempts and ED and MD symptoms across cisgender men, women, and transgender and gender expansive (TGE) youth. 940 adolescents and young adults (57.4% cisgender women, 33.8% cisgender men, 8.8% TGE) completed questionnaires about weight change attempts, ED and MD symptoms. Women and TGE individuals attempted to lose weight more often than men, while men attempted to gain weight more often. All genders endorsed weight loss and gain attempts for different purposes. Weight loss attempts related to ED symptoms and appearance intolerance, whereas weight gain attempts related to MD symptoms across genders. In women, all weight change attempts related to greater functional impairment due to exercise. Findings highlight the need for tailored interventions to address desires to change one's body and underscore the harmful effects of weight change attempts across genders.

This theoretical review paper offers a sociocultural-developmental framework for understanding LGBTQ+ adolescents' body image concerns and disordered eating risk. The Pride Framework integrates well-established sociocultural theories and extant empirical research, drawing from objectification theory, the tripartite influence model, minority stress theory, and intersectionality theory. The Pride Framework situates sociocultural appearance pressures within the adolescent developmental context, wherein biological, cognitive, and social transitions exacerbate the likelihood of body image disturbances and eating pathology. Various processes are then posited to link these sociocultural-developmental pressures to body image concerns and disordered eating. Crucially, this framework underscores that LGBTQ+ status itself does not pose a risk for body dissatisfaction and eating disorders. Instead, it is the experience of residing in a society that stigmatizes LGBTQ+ identities that increases youth's vulnerabilities. LGBTQ+ health researchers and practitioners are encouraged to engage in collaborative efforts with the aim of fostering acceptance for LGBTQ+ youth. This, in turn, could support normative adolescent identity exploration processes within sociocultural settings that are both affirming and inclusive, potentially mitigating adverse health consequences associated with body image disturbances.

Tattooed individuals often express the positive effects of wearing body art toward improved self-image and confidence. This research builds on prior data exploring the positive effects of tattooing and investigates how tattoos impact one's relationship to eating disorder (ED) recovery and body image. We held three focus groups lasting 60 minutes each, recruiting participants via purposive snowball sampling (n = 15), with additional opportunities to respond to focus group prompts asynchronously. Eligible participants were individuals with lived experience of an ED, self-identified as being in recovery, had three or more tattoos, and spoke English. Participants predominantly held gender-expansive (n = 4 Non-Binary, n = 3 Genderqueer, n = 3 Cisgender Women, n = 3 Transgender, n = 2 Transmasculine, n = 2 Gender Non-Conforming, n = 2 Intersex, n = 1 Cisgender Man) and non-heterosexual identities. Focus groups were held between April 2021 and July 2023 and followed a semi-structured interview format. Primary analyses focused on participants' responses to open-ended prompts regarding how they understood the relationships between tattooing, body image, and ED recovery. Thematic analysis identified four core themes: Tattooing allowing for embodiment, tattooing allowing for recovery-oriented behaviors, tattooing enabling positive body image, and tattooing facilitating empowerment. An overarching message was that tattooing is a therapeutic and transformative process, allowing for self-determination. Participants indicated that tattooing can be experienced as a powerful mechanism for behavioral change and shifts in relationship to one's body. Participants expressed that tattooing can be an effective route towards both gender euphoria and body liberation, enhancing one's ability to maintain ED recovery.

Transgender and gender diverse (TGD) young adults experience elevated risk for eating disorders (ED), partially due to cissexist discrimination and victimization; less is understood about how socioeconomic determinants contribute to their ED risk. Qualitative data collected from 66 TGD young adults (18-30 years old; 29% self-identified as transgender women, 29% as transgender men, 39% as nonbinary people, and 3% as another gender identity (e.g., māhū)) in eight asynchronous online focus groups explored how socioeconomic determinants in conjunction with other dimensions of identity and lived experience shape disordered eating behavior (DEB) and ED risk. Participants described how economic barriers-including poverty and dependency on others (e.g. parents for health insurance)-and challenges produced by insurance and healthcare systems impeded healthcare access to the detriment of their overall mental health and risk for ED. In addition, participants shared different ways they leveraged financial resources to cope with stress, sometimes in ways that impelled disordered eating behaviors. Finally, participants described how poverty, socioeconomic advantage and disadvantage, and classism compound other systems of oppression (e.g. racism, ableism, weight bias) to adversely impact their general health and ED risk.

This updated meta-synthesis explores further dimensions of the lived experience of severe and enduring anorexia nervosa (SE-AN) since recent contention regarding proposed "terminal anorexia nervosa (T-AN)". The paper aims to update the original synthesis and to situate participant responses to the category of "T-AN". Thus, extending the proposed conceptualization of the SE-AN experience. A systematic search identified published scholarship (between August 2022 and July 2023), derived from five bibliographic databases. A comprehensive methodology combining Interpretative Phenomenological Analysis and a meta-ethnographic framework enabled the synthesis of meta-themes across 9 new studies. These meta-themes were mapped onto the primary synthesis to further develop upon the earlier LE conceptualization of SE-AN. Nine extracted papers expanded the voices to 447 people within 45 studies. All papers affirmed and enriched the previous themes, and a novel theme was generated from the recent papers. The new theme, "walking on a knife's edge, caught between worlds", informed an expanded conceptualization of SE-AN, termed the Web of Hope. Thus, demonstrating how participants held onto hope in the face of the SE-AN experience. Death, dying and "terminality", were notably absent in the 36 papers in the previous meta-synthesis. Since the proposal of the category of "terminal anorexia" in 2022, studies on the lived experience of SE-AN increasingly focused on how people hold onto hope alongside SE-AN. The findings further drive the field to reflect on therapeutic interventions, labelling and diagnosis, in the face of unknowns, on the premise of "first, do no harm".

Pregnancy represents a crucial timepoint to screen for disordered eating due to the significant adverse impact on the woman and her infant. There has been an increased interest in disordered eating in pregnancy since the COVID-19 pandemic, which has disproportionately affected the mental health of pregnant women compared to the general population. This systematic review is an update to a previous review aiming to explore current psychometric evidence for any new pregnancy-specific instruments and other measures of disordered eating developed for non-pregnant populations. Systematic searches were conducted in PubMed, ProQuest, PsycInfo, CINAHL, Scopus, MEDLINE, and Embase from April 2019 to February 2024. A total of 20 citations met criteria for inclusion, with most studies of reasonable quality. Fourteen psychometric instruments were identified, including two new pregnancy-specific screening instruments. Overall, preliminary psychometric evidence for the PEBS, DEAPS, and EDE-PV was promising. There is an ongoing need for validation in different samples, study designs, settings, and administration methods are required. Similar to the original review on this topic, we did not find evidence to support a gold standard recommendation.

Youth with restrictive-eating disorders (EDs) often experience significant distress and difficulty with treatment adherence during nutritional rehabilitation. This study assessed whether youth with restrictive EDs and premorbid overweight/obesity admitted for inpatient nutritional rehabilitation experience greater psychological distress and difficulty with treatment adherence than youth with premorbid BMI <85th percentile. A retrospective chart review examined 150 youth hospitalized for medical complications of restrictive EDs. Rates of nasogastric tube (NGT; used when youth could not complete meals), agitation medication use, and disposition recommendation were compared across premorbid BMI groups. Patients with premorbid overweight/obesity were three times more likely to require NGT feeds. These findings suggest greater challenges with nutritional rehabilitation, specifically consuming nutrition orally, in patients with premorbid overweight/obesity, highlighting the need for early and individualized psychological support for this vulnerable patient population.

Objective: We investigated weight stereotypes in the recognition and referral of eating disorders (EDs) by assessing if recognition, health care referral, perceived acceptability, perceived distress, and perceived prevalence of an ED differ depending on the weight of the subject in the vignette.

Method: Community participants (N = 180, age = 19-74) read three different vignettes describing three females with different EDs [anorexia nervosa/atypical anorexia nervosa (AN/AAN), bulimia nervosa (BN), binge eating disorder (BED)] and were randomized to three different experimental conditions concerning an individual with a different weight (overweight, normal, and underweight).

Results: Across EDs, participants were more likely to recognize a problem, refer for treatment, and rate a higher perceived level of distress in the vignettes of overweight individuals than in the vignettes of normal weight individuals. For BED, a larger proportion of participants in the overweight condition classified the issue described in the vignette as a form of eating pathology compared to the normal weight condition.

Discussion: These results highlight several weight stereotypes that exist in the recognition and health care referral of EDs. Future ED education and awareness programs should emphasize that EDs can occur in any individual, regardless of their weight.

Those with eating disorders (EDs) characterized by purging behaviors tend to show more impulsivity than those diagnosed with restrictive eating, who tend to show more compulsivity. Impulsive choice (i.e. a type of impulsivity) is a common factor among eating disorders that is less understood. Delay discounting is a measure of choice impulsivity, examining the decrease in value of delayed outcomes. In this exploratory study, we examined associations between eating disorder type, age and delay discounting among patients at a residential ED treatment center (N = 178). Our findings showed that those diagnosed with bulimia nervosa had higher delay discounting (i.e. more impulsivity) at intake compared to anorexia nervosa, binge eating disorder, and other eating types but there were no significant differences. Those diagnosed with bulimia nervosa, as well as those with ARFID and unspecified ED showed a preference for delayed rewards at discharge, but there were no significant differences among ED types. Moderation analyses showed that age, ED type, nor the interaction did not significantly predict delay discounting at intake or discharge. To conclude, those with bulimia nervosa demonstrate less impulsive choice at discharge from a residential ED treatment center. However, additional research is needed given the variability of sample sizes in this study.
