ABSTRACT

This exploratory study aimed to describe the lived experiences of queer women affected by eating and weight-related concerns. Qualitative data from young queer women (n = 105; Age = 23.6 ± 3.4 years) with eating and weight-related concerns in response to open-ended questions related to the influence of gender identity and body image on weight concern, behaviours, and perception were analysed using reflexive thematic analysis. Nine themes were created to describe participants' experiences: (1) compensation for other internalised stigma, (2) to suppress body parts that can be gendered or sexualised, (3) comparisons to romantic partners' bodies, (4) media representations, (5) queer signalling, (6) queerness as protective, (7) gender expression and dysphoria, (8) societal expectations of women's bodies, and (9) internalisation of body/beauty ideals. Seven sub-themes were created to represent beauty ideals for specific subcultural communities (e.g. femme, butch). Findings suggest that queer women attribute individual, interpersonal and social factors to weight concerns, behaviours and perceptions. Findings highlight how complex tensions between the beauty/body ideals experienced in cisheteronormative and queer spaces influence eating and weight concerns among queer women. Gender, sexual orientation and subcultural ideals intersect in important ways, and may be useful to consider when screening, treating and preventing eating and weight concerns among queer women.

ABSTRACT

BACKGROUND: The Avoidant Restrictive Food Intake Disorder - Genes and Environment (ARFID-GEN) study is a study of genetic and environmental factors that contribute to risk for developing ARFID in children and adults. METHODS: A total of 3,000 children and adults with ARFID from the United States will be included. Parents/guardians and their children with ARFID (ages 7 to 17) and adults with ARFID (ages 18 +) will complete comprehensive online consent, parent verification of child assent (when applicable), and phenotyping. Enrolled participants with ARFID will submit a saliva sample for genotyping. A genome-wide association study of ARFID will be conducted. DISCUSSION: ARFID-GEN, a large-scale genetic study of ARFID, is designed to rapidly advance the study of the genetics of eating disorders. We will explicate the genetic architecture of ARFID relative to other eating disorders and to other psychiatric, neurodevelopmental, and metabolic disorders and traits. Our goal is for ARFID to deliver "actionable" findings that can be transformed into clinically meaningful insights. TRIAL REGISTRATION: ARFID-GEN is a registered clinical trial: clinicaltrials.gov NCT05605067.

ABSTRACT

PURPOSE: To examine differences in elevated eating disorder risk and self-reported eating disorder diagnosis across subgroups of transgender and gender diverse (TGD) college students. METHODS: Data from 5057 TGD college students participating in the national Healthy Minds Study between 2014 and 2019 were analyzed. Chi-square tests and logistic regression analyses examined heterogeneity in prevalence and odds of elevated eating disorder risk, as measured by the SCOFF, and self-reported eating disorder diagnosis by gender, as well as by intersecting gender and sexual orientation identities. RESULTS: Genderqueer and/or non-conforming college students reported the highest prevalence of elevated eating disorder risk (38.8%) relative to gender expansive students. Genderqueer and/or non-conforming (11.1%), gender expansive (12.3%), and trans men and/or transmasculine students (10.5%) reported higher prevalence of a self-reported eating disorder diagnosis relative to trans women and/or transfeminine students (6.3%). Heterosexual or straight trans men had lower odds of eating disorder risk and self-reported diagnosis relative to trans men with a minoritized sexual orientation. CONCLUSIONS: Genderqueer and/or non-conforming college students may be at heightened eating disorder risk. Moreover, a heterosexual and/or straight sexual orientation was associated with lower odds of elevated eating disorder risk and self-reported eating disorder diagnoses among trans men and genderqueer and/or non-conforming college students, but this finding did not hold for other groups. College campuses should aim to reduce eating disorder risk among TGD students.

ABSTRACT

Individuals with eating disorders (EDs) are at significant risk for increases in symptomatology and diminished treatment access during the COVID-19 pandemic. Environmental precautions to limit coronavirus spread have affected food availability and access to healthy coping mechanisms, and have contributed to weight-stigmatizing social media messages that may be uniquely harmful to those experiencing EDs. Additionally, changes in socialization and routine, stress, and experiences of trauma that are being experienced globally may be particularly deleterious to ED risk and recovery. This paper presents a brief review of the pertinent literature related to the risk of EDs in the context of COVID-19 and offers suggestions for modifying intervention efforts to accommodate the unique challenges individuals with EDs and providers may be experiencing in light of the ongoing public health crisis.

ABSTRACT

This study examined whether exposure to weight discrimination modified the association between sexual orientation, self-reported eating disorders, self-reported depression and academic impairment in a large sample of college students. Participants (n = 13,782) were from the 2015-2018 College Student Health Survey. Logistic regressions tested whether weight discrimination magnified psychological health concerns and academic impairment in sexual minority students (i.e., lesbian, gay) relative to their heterosexual peers and were stratified by gender (cisgender men and cisgender women). Sexual minority men and women reported more weight discrimination, eating disorders, depression, and academic impairment than their heterosexual peers, even after controlling for BMI and race. Among sexual minority men and women, weight discrimination was associated with increased eating disorders and academic impairment, but not depression. Weight discrimination increased the rate of eating disorders, depression, and academic impairment, however, the rate was still higher among sexual minority students regardless of weight discrimination status or gender. College-based interventions should aim to reduce weight stigmatization and its associated influence on psychological health and academic functioning, and address the needs of sexual minority college students, as they may be at highest risk. Clinicians should work to reduce the harms of weight discrimination, particularly in sexual minority young adults.

ABSTRACT

OBJECTIVE: Although current treatments are effective for some patients with eating disorders, a large number of patients remain partially or fully symptomatic post-treatment. This may be related to poor utilization of treatment skills outside of the therapy office. Smartphone applications that can detect and intervene during moments of need could facilitate such skill use between sessions. METHOD: Individuals (N = 16) participated in a small pilot open trial where they received 21 sessions of in-person Integrative Cognitive-Affective Therapy (ICAT) therapy an app (iCAT+) that delivers ecological momentary interventions (EMI) in response to user-entered data. Data were collected on the feasibility and acceptability of this treatment approach and on preliminary indicators of treatment outcomes. RESULTS: Participants found iCAT+ as a treatment augmentation acceptable and indicated it had clinical utility as an adjunct to in-person therapy, although analyses indicated poor compliance with data entry needed to trigger EMI delivery. This suggests that long-term use of EMI requiring ongoing data entry is infeasible. CONCLUSIONS: We describe lessons learned from our initial pilot trial and future directions for the development of impactful EMI systems that can be used to augment in-person therapies.

ABSTRACT

People with eating disorders (ED) have elevated rates of suicidal thoughts and behaviors. We used network analysis to identify symptoms that bridge EDs and suicidality, as well as central symptoms within the network, among 3 groups of adults. Participants were either (a) clinical psychiatric outpatients without current EDs (n = 538), (b) clinical psychiatric outpatients with a lifetime suicide attempt (n = 166), or (c) people with current EDs (n = 238). Networks were jointly estimated among groups. Within the Suicide Attempt and ED groups, interoceptive deficits and pain tolerance emerged as important bridge symptoms, whereas feeling inadequate was an important bridge symptom in the Clinical Outpatient group. Within all groups, having thoughts of killing oneself and feeling inadequate were central, meaning that they were most strongly connected to all other symptoms in the networks. Further, results indicate that a similar problem-interoceptive impairment-may link ED symptoms and suicidality both within people with EDs and people with suicide attempts. Overall, these findings are consistent with the notion that EDs and suicidality may bidirectionally influence one another, possibly through shared mechanisms (e.g., interoceptive impairment) or direct pathways (e.g., suicidal ideation being strongly connected to ED symptoms), though prospective work is needed to test these possibilities.

ABSTRACT

OBJECTIVE: The purpose of the current study was threefold: (a) compare rates of self-reported anorexia nervosa (AN), self-reported bulimia nervosa (BN), and eating pathology-specific academic impairment (EAI) by gender identity (cisgender men, cisgender women, transgender or genderqueer) and sexual orientation (gay or lesbian, bisexual, unsure, other), (b) examine associations between gender identity, sexual orientation, and eating outcomes, and (c) identify for whom rates of eating disorder diagnosis and impairment is greatest. METHOD: The study includes a sample of Minnesota students (n = 13,906) who participated in the College Student Health Survey from 2015 to 2018. Chi-square tests with bootstrapping examined differences in eating pathology rates between groups. Adjusted logistic regressions tested the association between gender identity, sexual orientation, and self-reported eating outcomes. RESULTS: Chi-square results revealed heightened rates of self-reported AN, self-reported BN, and EAI in cisgender women, transgender or genderqueer, and sexual minority (e.g., lesbian or bisexual) students. Logistic regression analyses in cisgender men and cisgender women revealed higher odds of self-reported AN, self-reported BN, and EAI in sexual minority students relative their heterosexual peers. Chi-square analyses indicated that bisexual cisgender women reported heightened rates of all three eating pathology measures relative to other sexual and/or gender (e.g., transgender) minority students. DISCUSSION: Individuals with marginalized gender and/or sexual orientation identities report heightened rates of eating pathology, with cisgender bisexual women reporting the poorest outcomes relative to individuals from other marginalized identities. Preventive efforts and more research are needed to understand the mechanisms driving this disparity and to reduce prevalence among marginalized groups.

ABSTRACT

Disordered eating frequently co-occurs with nonsuicidal self-injury (NSSI), and evidence suggests that the co-occurrence of these behaviors is associated with heightened emotion dysregulation. However, little is known about the relationship between restrictive eating and NSSI, and the significance of their co-occurrence. This study examined cross-sectional associations between self-reported restrictive eating, NSSI, and putative mechanisms of emotion regulation and interpersonal problems in a non-clinical sample of undergraduate students (N = 98, 80.6% female), using the Dietary Restriction Screener (Haynos & Fruzzetti, 2015), Deliberate Self-Harm Inventory (Gratz, 2001), Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2006), and Inventory of Interpersonal Problems-Personality Disorders-25 (Kim & Pilkonis, 1999). Hierarchical logistic regression analyses indicated that restrictive eating was associated with NSSI above and beyond the influence of binge eating, purging, and relevant covariates (B = 2.04, p < 0.001). In addition, multivariate analyses of variance revealed that the co-occurrence of restrictive eating and NSSI was associated with greater difficulties accessing and implementing effective, rather than impulsive, emotion regulation strategies when distressed than either behavior alone (p < 0.001). Findings highlight the seriousness of restrictive eating even within a nonclinical sample, as it is associated with heightened probability of NSSI and clinical severity among those who engage in co-morbid NSSI. Healthcare providers are encouraged to screen for NSSI among individuals with restrictive eating. In addition, a focus on improving emotion regulation and interpersonal skills may enhance prevention and intervention efforts for individuals with co-occurring restrictive eating and NSSI behaviors.

ABSTRACT

This study examined the prevalence of reported suicide attempts among family members of individuals with an eating disorder (ED). 1870 individuals presenting for ED treatment reported whether their family members ever made a suicide attempt using the Eating Disorders Questionnaire. A lifetime suicide attempt by any family member was reported by 10.8% (n = 202) of the sample and ranged from 7.0% of those with eating disorder not otherwise specified to 16.1% of those with purging disorder. Controlling for age and gender, individuals with bulimia nervosa had a higher prevalence of any familial suicide attempt and mother suicide attempt than individuals with EDNOS; no other differences were observed across ED diagnoses. There were no differences in prevalence of reported suicide attempts made by fathers, brothers, sisters, uncles, or aunts by ED diagnosis. Findings support a growing literature indicating a familial association between EDs and suicide risk.

ABSTRACT

BACKGROUND: This study examined the associations between specific dimensions of emotion dysregulation and eating disorder (ED) symptoms and behaviors, non-suicidal self-injury (NSSI), and suicide attempts in a heterogeneous ED sample. METHODS: Participants (N=110) completed the Difficulties in Emotion Regulation Scale (DERS), the Eating Disorder Examination Questionnaire (EDE-Q), and self-reported the presence of lifetime NSSI and a lifetime suicide attempt. RESULTS: The EDE-Q global score, a primarily cognitive measure of ED symptoms, was significantly positively correlated with DERS strategies, clarity, and awareness subscale scores and DERS total score (ps<0.01). Only the strategies subscale was uniquely positively associated with EDE-Q global score in a multivariate regression analysis. There was no association between the frequency of binge eating or frequency of driven exercise and any of the DERS subscale scores or total score (ps>0.01). Frequency of purging was significantly, positively associated with DERS impulse subscale score and total score (p<0.01). None of the DERS subscale scores were significantly different between those with and without NSSI or between those with and without a lifetime suicide attempt (ps>0.01). CONCLUSIONS: Findings indicate that in a heterogeneous ED sample, emotion regulation deficits are more strongly associated with cognitively-oriented symptoms of EDs than behavioral symptoms such as a binge eating, purging, driven exercise, NSSI, or suicide attempts.

ABSTRACT

OBJECTIVE: The Interpersonal Theory of Suicide (IPTS) model has not been fully tested in a clinical eating disorder (ED) population. METHOD: Participants (N = 114) completed questionnaires assessing suicidal ideation (SI), suicide attempts (SA), and constructs of the IPTS. Logistic regressions determined whether thwarted belongingness and perceived burdensomeness were associated with lifetime SI. Among those who endorsed lifetime SI, logistic regressions were used to determine whether elements of the acquired capability for suicide (fearlessness about death and painful and provocative events) were associated with lifetime SA. RESULTS: Sixty-five participants (57.0%) had lifetime SI and 24 (21.1%) had lifetime SA. Thwarted belongingness (P < 0.001) and perceived burdensomeness (P < 0.01) were associated with lifetime SI. Painful and provocative events were associated with lifetime SA (P < 0.03). DISCUSSION: The IPTS was partially supported. Targeting interpersonal variables may be important in treating and preventing suicidality. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:162-165).

ABSTRACT

Currently, research support is strongest for family-based treatment (FBT) for the treatment of anorexia nervosa (AN) in adolescents. However, a strong evidence base for treatments for older adolescents and young adults with AN is lacking. Emphasizing social support in the treatment of AN may be beneficial for older adolescents and young adults with AN. This paper provides a brief review of the literature on FBT for adolescent AN and provides a case example of adolescent AN treated with FBT. We then discuss novel treatments that have incorporated social support for older adolescents and young adults with AN, such as modified FBT and couples-based interventions. We provide case studies of each of these novel treatment approaches as well. Additionally, this paper highlights and discusses developmental considerations and challenges in working with older adolescents and young adults with AN.

ABSTRACT

OBJECTIVE: Individuals with bulimia nervosa (BN) frequently endorse risky behaviors such as self-harm and substance use. However, no studies of BN to date have examined factors associated with engaging in individual or co-occurring risky behaviors. Given that individuals with BN often have personality psychopathology, which has been linked to symptoms and course of illness, this study sought to examine how personality may differentiate engagement in risky behaviors among BN individuals. METHOD: A sample of 133 women with BN completed self-report measures of personality psychopathology at baseline, and then reported on bulimic and risky behaviors (e.g., substance misuse, self-harm) over 2 weeks using ecological momentary assessment. A series of hierarchical multiple regression analyses were conducted to examine the unique associations between state-level predictor variables (each risky behavior, e.g., substance misuse, and combination of risky behaviors, e.g., substance misuse plus self-harm) and trait-level personality constructs. RESULTS: Substance misuse behavior, above and beyond all other risky behaviors, was significantly associated with higher scores on trait dissocial behavior (P = 0.004). DISCUSSION: Substance misuse in BN has a unique association with dissocial behavior, a personality trait characterized by hostility, impulsivity, and entitlement. These results suggest that targeting personality variables may help facilitate more effective treatment of risky behaviors, including substance use in BN. © 2016 Wiley Periodicals, Inc.

ABSTRACT

OBJECTIVE: To describe the frequency of self-weighing and reactions to prescribed weekly weighing among individuals with eating disorder (ED) diagnoses, and to compare individuals weighing more or less frequently on mass index (BMI) and the Eating Disorder Examination (EDE) subscales. METHOD: Baseline EDE and demographics from five studies (N = 758). RESULTS: Self-weighing was most frequent among individuals with anorexia nervosa (AN), followed by those with bulimia nervosa (BN) and binge eating disorder (BED). On average, participants reacted moderately negative to prescribed weekly weighing. No relationship between weighing frequency and BMI was evident in any sample. There was indication of greater pathology (i.e., restraint, shape concern, weight concern, global) in AN with more frequent weighing. In BN, mixed evidence emerged to support a relationship between more frequent weighing and higher shape concern, weight concern, and global score. In BED, higher restraint was found in those who weighed versus those who did not. DISCUSSION: Weighing frequency in each eating disorder (ED) sample was to some extent associated with greater ED severity, but not BMI. Future research should examine relationships between self-weighing, reactions to changing weighing frequency, and ED symptomatology in both ED and non-ED groups to understand the impact of self-weighing in heterogeneous populations. © 2016 Wiley Periodicals, Inc.

ABSTRACT

OBJECTIVE: The purpose of this investigation was to examine whether narrowing the criteria of anorexia nervosa (AN) subtypes among adults based on further delineations of current binge eating and purging (i.e., binge eating only, purging only, binge eating and purging, and restricting only) improves the potential clinical utility of the current DSM-5 system that specifies two types (i.e., current binge eating and/or purging and restricting, specified as the absence of current binge eating and/or purging). METHOD: Self-reported eating disorder and psychiatric symptoms based on the Eating Disorder Questionnaire were examined in 347 adults from a multisite clinical sample who met DSM-IV criteria for AN. Classification based on binge eating and purging symptoms yielded the following subtypes: 118 restricting only (AN-R; no current binge eating or purging); 133 binge eating and purging (AN-B & P; current binge eating and purging); 43 binge eating only (AN-B; current binge eating and no current purging); and 53 purging only (AN-P; current purging and no current binge eating). RESULTS: The AN-R group had lower current body mass index compared to AN-B & P and AN-P with no group differences in highest, lowest, or desired body mass index. The probability of amenorrhea was higher for the AN-R and AN-B & P groups than the AN-P group. The probability of diet pill use was elevated for the AN-B & P and AN-P groups compared to the AN-R group. The AN-P group also had a higher probability of fasting than the AN-R group. The probability of substance use including tobacco was lower in the AN-R group than the other three groups. No group differences were found on measures of hospitalization, body image, physical symptoms, exercise, or dieting behaviors. CONCLUSIONS: These findings do not support the validity or clinical utility of classifying AN into narrower subtypes based on current binge eating, purging, and binge eating with purging given that few differences were found among groups who reported any combination of current binge eating and purging. Future research is needed to replicate these findings and to further examine the AN subtype classification schemes.

ABSTRACT

The current study examined the association between affect and self-reported alcohol intoxication in women with bulimia nervosa (BN; N=133). Participants completed a two-week ecological momentary assessment protocol. Momentary global positive affect (PA) and negative affect (NA), as well as the facets of NA (fear, guilt, hostility and sadness), were measured. Forty-five participants endorsed that they "got drunk" during the study period. Daily mean and variability of global PA and NA were compared between days with self-reported alcohol intoxication and days without self-reported alcohol intoxication. Trajectories of affect were modeled prior to and following episodes of self-reported alcohol intoxication. There were no differences in the mean or variability of PA or NA on days characterized by self-reported alcohol intoxication compared to days with no self-reported alcohol intoxication (ps>0.05). PA decreased significantly prior to self-reported alcohol intoxication and remained stable afterwards. There were no changes in global NA before or after self-reported alcohol intoxication, but an examination of the facets of NA showed that sadness increased following episodes of self-reported alcohol intoxication. These findings showed only partial support for a negative reinforcement model of alcohol use in women with BN.
