Predictors of Outpatient and Inpatient Service Utilization Among Publicly-Insured Youth With Eating Disorders

INTRODUCTION

Although eating disorders (EDs) affect youth from all socioeconomic backgrounds, little is known about the treatment experiences of under-resourced youth with EDs. To address this gap, we examined patterns of outpatient and inpatient service utilization among publicly-insured youth with EDs in California and potential disparities for youth with additional marginalized identities.

METHOD

Participants were identified from the full sample of California Medicaid/Medi-Cal beneficiaries aged 7-18 with ≥ 1 service episode between January 1, 2014 and December 31, 2016. Claims data were extracted for youth with a full year of claims after the first known ED diagnosis (N = 3311) to analyze outpatient mental health, outpatient medical/physical, inpatient mental health, and inpatient medical/physical service use across ED diagnosis and demographic characteristics (sex, age, race/ethnicity, and preferred language).

RESULTS

Outpatient individual and family therapy service utilization was low across ED diagnoses (4-7 individual therapy sessions and ≈5 family therapy sessions annually). Conversely, hospitalization rates were high, particularly among youth with anorexia nervosa (27.8%) and bulimia nervosa (30.0%). Youth with other specified feeding or ED had high medical service utilization, with more days of outpatient medical care and greater odds of medical hospitalization than youth with all other diagnoses. Latinx youth, Black youth, and boys tended to receive fewer services after accounting for diagnosis, with disparities particularly pronounced for Latinx youth.

CONCLUSIONS

Publicly-insured youth with EDs in California experience high hospitalization rates but receive limited outpatient therapy. Additional research is needed to identify possible unmet needs and factors contributing to treatment disparities among these youth.

Interdisciplinary perspectives on accessing specialty evidence-based treatment for Medicaid-insured adolescents with eating disorders

BACKGROUND

Family-based treatment (FBT), the leading intervention for adolescents with anorexia nervosa (AN), is severely understudied in outpatient care settings that serve publicly-insured populations. Many individuals with public insurance are lower-income, racially and ethnically diverse, and experience barriers to accessing evidence-based interventions for eating disorders (EDs).

METHODS

Semi-structured interviews were conducted with ten interdisciplinary providers who provide specialty care to youth with EDs in an inpatient and/or outpatient medical setting. Interview questions were focused on the interdisciplinary providers' experiences of caring for individuals with EDs, with a focus on differences in care for those with private insurance compared to public insurance. The interviews took place two years after training in FBT was delivered to mental health providers in San Francisco County, which created opportunities to explore provider perspectives on collaborating with newly-trained mental health providers in the community implementing FBT with publicly-insured youth.

RESULTS

Content analysis converged on three themes: the critical importance of supporting mental health treatment within the context of medical care, complex challenges when helping patients and their families navigate publicly-funded health care systems, and the overall positive impact of the FBT rollout in San Francisco County. Participants emphasized greater confidence in patient outcomes when collaborating with FBT providers and noted discord when working with providers not trained in EDs or FBT. Referral systems, weight-based stigma, and a lack of appropriate services were highlighted as significant barriers to care. To facilitate treatment engagement in publicly-insured populations, participants stressed the importance of clinicians providing psychoeducation and providing services with a high degree of cultural competence. Participants expressed that patients' ability to access FBT and providers' ability to collaborate on cases markedly improved following the county training, increasing their sense of efficacy in delivering adequate patient care.

CONCLUSIONS

The discussed themes highlight the importance of access to FBT for individuals in underserved communities, which can significantly reduce both provider and patient burden. Despite various barriers to utilizing FBT in publicly-funded settings, clinicians stressed that cultural adaptations increase the implementation of and facilitate family engagement in FBT, which is consistent with previous literature examining evidence-based intervention implementation science.

Socioeconomic inequity in the utilization of healthcare among people with eating disorders in Australia

BACKGROUND

Little is known about socioeconomic equity in access to healthcare among people with eating disorders in Australia. This study aims to measure the extent of inequity in eating disorder-related healthcare utilization, analyze trends, and explore the sources of inequalities using New South Wales (NSW) administrative linked health data for 2005 to 2020.

METHODS

Socioeconomic inequities were measured using concentration index approach, and decomposition analysis was conducted to explain the factors accounting for inequality. Healthcare utilization included: public inpatient admissions, private inpatient admissions, visits to public mental health outpatient clinics and emergency department visits, with three different measures (probability of visit, total and conditional number of visits) for each outcome.

RESULTS

Private hospital admissions due to eating disorders were concentrated among individuals from higher socioeconomic status (SES) from 2005 to 2020. There was no significant inequity in the probability of public hospital admissions for the same period. Public outpatient visits were utilized more by people from lower SES from 2008 to 2020. Emergency department visits were equitable, but more utilized by those from lower SES in 2020.

CONCLUSIONS

Public hospital and emergency department services were equitably used by people with eating disorders in NSW, but individuals from high SES were more likely to be admitted to private hospitals for eating disorder care. Use of public hospital outpatient services was higher for those from lower SES. These findings can assist policymakers in understanding the equity of the healthcare system and developing programs to improve fairness in eating disorder-related healthcare in NSW.

Trends and social determinants of the obesity epidemic among reproductive-age women in ten Asian countries

The rapid epidemiological transition in Asian countries, resulting from the rising trend of urbanisation and lifestyle changes, is associated with an increasing risk of obesity in women of reproductive age. This is the first study to investigate the trends and population-attributable fraction (PAF) of obesity, and the interaction effects of education and wealth on obesity among reproductive-age women aged 15-49 years in ten Asian countries. This cross-sectional study examined the most recent (2000 to 2022) Demographic and Health Surveys (DHS) data from ten Central and Southeast Asian countries. Multilevel multinomial logistic regression models were used to compute odds ratios (ORs). PAFs adjusted for communality were calculated using adjusted ORs and prevalence estimates for each risk factor. This study included a weighted sample of 743,494 reproductive-age women. All the countries showed an increasing trend for obesity and a decreasing trend for underweight, except for the Maldives. The highest PAFs of obesity were associated with women who were married (PAF = 22.2%; 95% CI 22.1, 22.4), aged 35-49 years (PAF = 16.4%; 95% CI 15.5, 17.1), resided in wealthy households (PAF = 14.5%; 95% CI 14.4, 14.5), watched television regularly (PAF = 12.5%; 95% CI 12.1, 12.8), and lived in urban areas (PAF = 7.8%; 95% CI 7.7, 8.0). The combined PAF showed that these five risk factors were associated with 73.3% (95% CI 71.8, 74.9) of obesity among reproductive-age women. Interaction analysis between women's education and household wealth revealed that having a secondary or higher level of education and residing in a wealthier household was associated with a lower risk of obesity (OR = 0.71, 95% CI 0.66, 0.76). The findings of this study suggest that, in order to address the rising rate of obesity among women in Asian countries, education and lifestyle modifications in urban areas should be a priority. Pakistan and the Maldives need to be a priority given the rapidly increasing trends in obesity and underweight subpopulations in their respective countries.

Adaptations to family-based treatment for Medicaid-insured adolescents with anorexia nervosa

Background

Family-based treatment (FBT) is the leading intervention for adolescents with anorexia nervosa (AN); however, it is under researched in socioeconomically disadvantaged and racially diverse youth.

Methods

Semi-structured interviews were completed with ten FBT clinicians who practice in publicly-funded settings. Interview questions were focused on implementation challenges, overall acceptability and appropriateness of FBT, and naturally-occurring treatment adaptations.

Results

Content analysis revealed common themes relating to the implementation of FBT in publicly-funded, community-based settings: acceptability and appropriateness, complexity and learnability, perceived core components of FBT, cultural adaptations, socioeconomic factors, logistical considerations, organizational and systemic barriers, training acceptability, participant's self-efficacy, and telehealth accommodations.

Conclusion

The discussed themes offer insights into the implementation of FBT for settings with limited resources, aligning with prior research on clinical adaptations for multicultural patients. Recognizing these themes can guide clinical adjustments and refine the adapted treatment model in real-world settings for patients facing systemic barriers.

"There is a paywall to my happiness": the influence of socioeconomic determinants on transgender and gender diverse young adults' experiences with eating disorders

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.

Exploring Demographic and Clinical Characteristics of Racially and Ethnically Diverse Youth With Eating Disorders Using California Medicaid Claims Data

OBJECTIVE

To explore the scope of diagnosed eating disorders among Medicaid-insured youth in California, and to describe the demographic characteristics of this population in a repeated annual cross-sectional study design.

METHOD

California Medicaid claims data were extracted for youth aged 7 to 18 years between January 2014 and December 2016. Participants included all youth who received an eating disorder diagnosis at any point in the study period (N = 8,075). Additional analyses compared youth with eating disorders who were continuously enrolled across all 3 years (n = 4,500) to random subsamples of continuously enrolled youth diagnosed with a mood or anxiety disorder (n = 4,128), a disruptive behavior disorder (n = 4,599), or a psychotic disorder (n = 4,290).

RESULTS

About one-half of youth with eating disorders were Latinx (58.5%, n = 2,634) and indicated Spanish as their preferred language (48.9%, n = 2,199). About one-half (51%, n = 2,301) of eating disorder diagnoses were unspecified. Latinx ethnicity and Spanish language were significantly more frequent among youth with eating disorders than among those with other disorders (F11.97, F362.75, p values <.0005).

CONCLUSION

The first examination of publicly insured youth with eating disorders revealed a highly diverse group of individuals among whom Latinx youth were particularly prevalent. However, past-year national prevalence estimates suggest that most eating disorder cases were undiagnosed.

PLAIN LANGUAGE SUMMARY

Eating disorders affect approximately 10% of the US population and lead to serious mental health and medical problems. This study used California Medicaid claims data from 2014 to 2016 to characterize the population of youth aged 7 to 18 years with diagnosed with an eating disorder (N = 8,075). The authors found the prevalence of eating disorders among youth aged 13 to 18 years was about 0.20% across all 3 years of the study, which is far below the expected prevalence and suggests that most eating disorders in youth go undiagnosed. About half of eating disorder diagnoses provided to youth with Medicaid insurance are unspecified, which may hinder receipt of appropriate treatment. Of youth with an eating disorder, about half were Latinx and reported Spanish as their preferred language. The authors also found differences in the prevalences of eating disorder diagnoses when analyzing youth by age, sex, and ethnicity. These results suggest that more standardized screening and assessment is needed to improve eating disorders detection and diagnosis, particularly for minoritized youth.

Eating Disorders In weight-related Therapy (EDIT) Collaboration: rationale and study design

The cornerstone of obesity treatment is behavioural weight management, resulting in significant improvements in cardio-metabolic and psychosocial health. However, there is ongoing concern that dietary interventions used for weight management may precipitate the development of eating disorders. Systematic reviews demonstrate that, while for most participants medically supervised obesity treatment improves risk scores related to eating disorders, a subset of people who undergo obesity treatment may have poor outcomes for eating disorders. This review summarises the background and rationale for the formation of the Eating Disorders In weight-related Therapy (EDIT) Collaboration. The EDIT Collaboration will explore the complex risk factor interactions that precede changes to eating disorder risk following weight management. In this review, we also outline the programme of work and design of studies for the EDIT Collaboration, including expected knowledge gains. The EDIT studies explore risk factors and the interactions between them using individual-level data from international weight management trials. Combining all available data on eating disorder risk from weight management trials will allow sufficient sample size to interrogate our hypothesis: that individuals undertaking weight management interventions will vary in their eating disorder risk profile, on the basis of personal characteristics and intervention strategies available to them. The collaboration includes the integration of health consumers in project development and translation. An important knowledge gain from this project is a comprehensive understanding of the impact of weight management interventions on eating disorder risk.

Does embedding pediatric eating disorder treatment in primary care bridge the access gap?

Given the numerous barriers to accessing child and adolescent eating disorder treatment, there is a need for innovation in how this care is delivered. Primary care-based eating disorder treatment has established proof-of-concept, yet it is unclear whether this model can bridge the treatment-access gap. This retrospective chart review study compared demographic and illness characteristics of 106 adolescents (M age = 15.1 years)  SD = 1.8 consecutively evaluated in a primary care-based eating disorder clinic with 103 adolescent patients (M age = 15.2 years)  SD = 2.2 seen consecutively in a specialty eating disorder clinic at the same medical center. Relative to adolescents in specialty care, those in the primary care group presented at a significantly higher BMI percentile, had less weight suppression, a shorter illness duration, lower rates of amenorrhea and lower scores on the EDE-Q Dietary Restraint subscale. In addition, more patients in the primary care group identified as non-white and had government/public assistance insurance compared to those in the specialty group. The results suggest that, compared to traditional specialty care clinics, embedded eating disorder treatment in primary care may reach a more racially and socioeconomically diverse group of adolescents when they are earlier in the course of their illness. Future research determining the relative effectiveness of this model as compared to interventions delivered in specialty care is needed.

A qualitative assessment of provider-perceived barriers to implementing family-based treatment for anorexia nervosa in low-income community settings

BACKGROUND

Family-based treatment (FBT) is a front-line empirically supported intervention for adolescent anorexia nervosa, but it is often inaccessible to families from lower income backgrounds, as it is most typically available in specialty research and private practice settings. In preparation for a pilot trial of FBT delivered in the home setting, this study qualitatively examined provider perceptions of implementing FBT in lower-income communities.

METHODS

Eating disorder clinicians working in community clinics (therapists, medical doctors, dietitians, and social workers; n = 9) were interviewed about their experiences using FBT. Interview transcripts were analyzed both deductively, using an approach consistent with applied thematic analysis, and inductively, using the Replicating Effective Programs implementation framework, to examine barriers to FBT implementation.

RESULTS

Prevailing themes included concern about the time and resources required of caregivers to participate in FBT, which may not be feasible for those who work full time, have other caregiving demands, and/or lack family support. Psychosocial problems outside of the eating disorder, such as food insecurity, other untreated mental health concerns (in themselves or other family members), or externalizing behaviors on the part of the adolescent, were also discussed as barriers, and participants noted that the lack of cohesive treatment teams in the community make it difficult to ensure continuity of care.

CONCLUSION

Findings from this qualitative study indicate the need to address systemic socioeconomic barriers to improve the efficacy of implementation of FBT in the community and to understand how provider perceptions of these barriers influence their uptake of FBT.

A case-control study to differentiate parents' personality traits on anorexia nervosa and affective disorders

Eating disorders (ED) and affective disorders (AD) in adolescent population and several investigations have pointed out that specific family dynamics play a major role in the onset, course, and maintenance of both disorders. The aim of this study was to extend the literature of this topic by exploring differences between parents' personality traits, coping strategies, and expressed emotion comparing groups of adolescents with different mental conditions (anorexia nervosa vs. affective disorder vs. control group) with a case-control study design. A total of 50 mothers and 50 fathers of 50 girls with anorexia nervosa (AN), 40 mothers and 40 fathers of 40 girls with affective disorder (AD), and 50 mothers and 50 fathers of 50 girls with no pathology that conformed the control group (CG) were measured with the Temperament and Character Inventory (TCI), the COPE Inventory, the Family Questionnaire (FQ), and psychopathology variables, anxiety, and depression. Both parents of girls with AN showed a significant difference in personality, coping strategies, and expressed emotion compared to both parents in the CG, while they presented more similarities to parents of girls in the AD group. Identifying personality traits, expressed emotion, coping strategies, and psychopathology of parents and their daughters will allow improvements in the interventions with the adolescents, parents, and families.

The need for more inclusive measurement to advance equity in eating disorders prevention

Eating disorder (ED) research and practice have been shaped by prevailing stereotypes about who EDs are most likely to affect. Subsequently, the field has prioritized the needs and concerns of affluent, cisgender, heterosexual, white girls and women to the exclusion of others, especially people marginalized based on their race, ethnicity, sexual orientation, and/or gender identity. However, EDs exist across diverse groups and actually occur with elevated prevalence in several marginalized groups. Growing research points to differences in the drivers of EDs in such groups (e.g. desire to attain the curvy rather than thin ideal; dietary restraint due to food insecurity rather than weight/shape concerns), yet tools typically used for screening and intervention evaluation do not capture eating pathology driven by such factors. In this commentary, we describe gaps in existing ED assessment tools and argue these gaps likely underestimate EDs among marginalized groups, bias who is invited, participates in, and benefits from ED prevention programs, and obscure potential group differences in the efficacy of such programs. We also discuss the potential of these ramifications to exacerbate inequities in EDs. Finally, we outline recommendations to overcome existing gaps in measurement and, consequently, advance equity in the realm of ED prevention.

Adaptations of an Online Cognitive-Behavioral Therapy Intervention for Binge-Purge Type Eating Disorders in Publicly-Insured and Uninsured Adults: A Pilot Study

Background Publicly-insured and uninsured individuals-many of whom are marginalized because of race/ethnicity, disability and/or sexual preferences-experience barriers to accessing evidence-based interventions for eating disorders (EDs). Additionally, EBIs have not been developed with or for diverse populations, exacerbating poor treatment uptake. Mobile technology is perfectly positioned to bridge this gap and increase access to low-cost, culturally-sensitive EBIs. Methods This study leverages a user-centered design approach to adapt an existing coached cognitive-behavioral therapy-based digital program and evaluate its usability in a sample of 11 participants with (sub)clinical binge-purge type EDs who are publicly-insured ( n  = 10) or uninsured ( n  = 1). Participants were primarily Non-Hispanic White ( n  = 8) women ( n  = 8). Two semi-structured interviews occurred with participants: one to assess treatment needs and the other to obtain app-specific feedback. Interviews were coded using inductive thematic analysis. Results Interview 1 feedback converged on three themes: Recovery Journey, Treatment Experiences, and Engagement with and Expectations for Online Programs. Participants endorsed facing barriers to healthcare, such as poor insurance coverage and a lack of trained providers, and interest in a coach to increase treatment accountability. Interview 2 feedback converged on three themes: Content Development, Participant Experiences with Mental Health, and Real-World Use. Participants liked the content but emphasized the need to improve diverse representation (e.g., gender, body size). Conclusions Overall, user feedback is critical to informing adaptations to the original EBI so that the intervention can be appropriately tailored to the needs of this underserved population, which ultimately has high potential to address critical barriers to ED treatment. Trial Registration This study was reviewed and approved by the Institutional Review Board (IRB) at the University California, San Francisco (IRB #22-35936) and the IRB at Washington University in St. Louis (IRB ID 202304167).

Impact of the COVID-19 pandemic on care for anorexia and bulimia nervosa in US military-connected adolescents and young adults

OBJECTIVE

This study examined the impact of the COVID-19 pandemic on healthcare engagement for anorexia nervosa (AN) and bulimia nervosa (BN) in a large, geographically diverse population.

METHOD

This repeated monthly, cross-sectional study queried Military Health System records of individuals aged 10-21 before and during the pandemic (February 2019-January 2022). ICD-10 codes identified encounters for AN and BN. Monthly rates of care were modeled as the number of unique individuals with an ICD-10-identified eating disorder-related encounter per month divided by the enrolled population. Poisson regression analysis evaluated rates of care stratified by eating disorder, clinical setting, and sex.

RESULTS

In a population of 1.76 million adolescents and young adults, 1629 individuals with AN or BN received care during the pre-pandemic period; 3256 received care during the pandemic. The monthly rate of care for females with AN during the pandemic increased in inpatient settings (adjusted relative risk [aRR]: 1.31 [1.16-1.49]) and outpatient settings (aRR: 1.42 [1.37-1.47]); monthly care rates in males with AN increased in the outpatient setting (aRR: 1.46 [1.28-1.67]). Females with BN had increased engagement in outpatient settings (aRR: 1.09 [1.03-1.16]); BN care for males showed no significant monthly changes during the pandemic period in either healthcare setting.

DISCUSSION

With increased rates of AN and BN disorder-related care during the pandemic, screening for eating disorder symptomatology may allow for timely diagnosis and intervention in periods of heightened stress. Pandemic-related increases in healthcare engagement may strain limited resources, emphasizing a need to expand accessibility of clinical expertise.

PUBLIC SIGNIFICANCE

This study indicates that monthly rates of healthcare engagement during the COVID-19 pandemic for AN and BN varied based on clinical setting and sex in an adolescent and young adult population. The increased number of individuals seeking eating disorder-related care, especially outpatient care, attributed to heightened stressors necessitates accessible professionals with eating disorder clinical expertise.

Industrial athletes, relative energy deficit in occupation, and equitable eating disorder treatment and recovery

OBJECTIVE

This paper highlights the gap in understanding and meeting the needs of individuals with eating disorders (EDs) who are engaged in manual labor and proposes a novel solution for meeting those needs.

METHODS

In this paper, we describe the rationale, considerations, and opportunities for research and practice that can be adapted and created to meet the needs of individuals with EDs who are engaged in manual labor, a group that may be underserved by current methods for treating EDs. We highlight the potential utility of the industrial athlete (IA) framework for this population, propose the term Relative Energy Deficit in Occupation ("RED-O"), and describe the potential applications of this framework and term for research, treatment, and public health promotion for EDs among individuals engaged in manual labor.

RESULTS

The IA framework and RED-O provide opportunities to address the unique needs of individuals with EDs who are also engaged in manual labor and who are disproportionately of low socioeconomic status through new and adapted research and clinical applications as well as advocacy and public health promotion.

DISCUSSION

Equitable recovery for people with EDs requires the ability to engage in activities necessary for occupational functioning, including the physical capacity necessary to participate fully in their work. As access to treatment increases, it is imperative that the needs of IAs are adequately addressed, especially those who are of lower socioeconomic status.

PUBLIC SIGNIFICANCE

The industrial athlete and relative energy deficit in occupation (RED-O) frameworks will enhance opportunities for identification and treatment of underserved and disadvantaged populations with eating disorders and reduce public health burden of eating disorders.

Intersecting gender identity and racial/ethnic inequities in eating disorder risk factors, symptoms, and diagnosis among U.S. college students: An intersectional multilevel analysis of individual heterogeneity and discriminatory accuracy

INTRODUCTION

There are documented inequities in eating disorders (EDs) by gender and race/ethnicity, yet, little is known about population-level prevalence of ED risk factors, symptoms, and diagnosis at the intersection of diverse gender and racial/ethnic identities.

METHODS

Data from the Healthy Minds Study 2015-2019 (N = 251,310 U.S. university students) were used in a multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA). Participants were nested in 35 intersectional strata given by all combinations of 5 gender and 7 racial/ethnic categories. Multilevel logistic models with participants at level 1 and intersectional strata at level 2 were used to estimate stratum-specific predicted prevalence estimates for self-reported thin-ideal internalization, ED symptoms, and ED diagnosis. The variance partition coefficient (VPC) was calculated to quantify the contextual effect of the strata.

RESULTS

There was considerable heterogeneity in the predicted prevalence of our ED outcomes across the strata (e.g., .3%-18.3% for ED diagnoses). There were large disparities in all three outcomes, with transgender participants of color having a higher predicted prevalence than expected based on the additive effects of gender and race/ethnicity. Moderation by race/ethnicity was also apparent, such that racial/ethnic disparities were wider within the cisgender groups relative to the transgender groups. VPCs indicated that ~10% of the total variance in ED outcomes was due to intersectionality between gender and race/ethnicity, over and above variance due to individual-level differences.

CONCLUSION

Findings suggest that gender and racial/ethnic disparities in EDs are interrelated, underscoring the need to develop preventive interventions centering health equity.

PUBLIC SIGNIFICANCE

Despite evidence that sexism, racism, and cissexism (i.e., anti-transgender prejudice) can impact EDs risk, little research examines the social patterning of EDs at the intersection of diverse gender and racial/ethnic identities. Using data from a sample of 250,000 U.S. university students, this study found that gender and racial/ethnic disparities in eating disorder risk are interrelated, highlighting the need to develop health equity centered preventive interventions.

Estimated prevalence of DSM-5 eating disorders in Norwegian adolescents: A community based two-phase study

OBJECTIVE

Little is known about the prevalence of DSM-5 eating disorders (EDs) in adolescents. In Norway, the most recent community-based prevalence study in adolescents was published more than 20 years ago. The aim of this study was to assess the prevalence of DSM-5 EDs in Norwegian adolescents using a two-phase design.

METHOD

A total of 1558 upper secondary school students (827 girls and 730 boys) (ages 16-19) were screened for at-risk ED pathology using the Eating Disorder Examination-Questionnaire short version (EDE-QS). A sub-sample of 99 adolescents (87 girls and 12 boys) subsequently participated in a clinical interview using the Eating Disorder Assessment for DSM-5 (EDA-5).

RESULTS

Eating pathology was common, with 19.9% of participants scoring at or above the applied EDE-QS cut-off. The estimated prevalence of any ED was 9.4% in the total sample, and 16.4% in girls. The number of boys who took part in the diagnostic interview was low, thus, diagnostic data from boys were not analyzed separately. Prevalence estimates of AN, BN, BED, and OSFED in girls were 2.7%, 1.1%, 1.9%, and 10.7%. Atypical AN was the most frequently assigned diagnosis in girls.

DISCUSSION

Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.

PUBLIC SIGNIFICANCE STATEMENT

In this study, 1558 adolescents, aged 16-19, were screened for ED pathology. A subsample completed a diagnostic interview using DSM-5 criteria. Results showed that one in five adolescents displayed problematic eating behaviors and cognitions. The estimated prevalence rate of any ED was 9.4%. Sampling biases limit generalizability of results. Additional population-based studies are warranted to assess the prevalence of EDs in Norwegian youth.

Prevalence and demographic variation of cardiovascular, renal, metabolic, and mental health conditions in 12 million english primary care records

BACKGROUND

Primary care electronic health records (EHR) are widely used to study long-term conditions in epidemiological and health services research. Therefore, it is important to understand how well the recorded prevalence of these conditions in EHRs, compares to other reliable sources overall, and varies by socio-demographic characteristics. We aimed to describe the prevalence and socio-demographic variation of cardiovascular, renal, and metabolic (CRM) and mental health (MH) conditions in a large, nationally representative, English primary care database and compare with prevalence estimates from other population-based studies.

METHODS

This was a cross-sectional study using the Clinical Practice Research Datalink (CPRD) Aurum primary care database. We calculated prevalence of 18 conditions and used logistic regression to assess how this varied by age, sex, ethnicity, and socio-economic status. We searched the literature for population prevalence estimates from other sources for comparison with the prevalences in CPRD Aurum.

RESULTS

Depression (16.0%, 95%CI 16.0-16.0%) and hypertension (15.3%, 95%CI 15.2-15.3%) were the most prevalent conditions among 12.4 million patients. Prevalence of most conditions increased with socio-economic deprivation and age. CRM conditions, schizophrenia and substance misuse were higher in men, whilst anxiety, depression, bipolar and eating disorders were more common in women. Cardiovascular risk factors (hypertension and diabetes) were more prevalent in black and Asian patients compared with white, but the trends in prevalence of cardiovascular diseases by ethnicity were more variable. The recorded prevalences of mental health conditions were typically twice as high in white patients compared with other ethnic groups. However, PTSD and schizophrenia were more prevalent in black patients. The prevalence of most conditions was similar or higher in the primary care database than diagnosed disease prevalence reported in national health surveys. However, screening studies typically reported higher prevalence estimates than primary care data, especially for PTSD, bipolar disorder and eating disorders.

CONCLUSIONS

The prevalence of many clinically diagnosed conditions in primary care records closely matched that of other sources. However, we found important variations by sex and ethnicity, which may reflect true variation in prevalence or systematic differences in clinical presentation and practice. Primary care data may underrepresent the prevalence of undiagnosed conditions, particularly in mental health.

The social epidemiology of binge-eating disorder and behaviors in early adolescents

BACKGROUND

Binge-eating disorder (BED) is the most common eating disorder phenotype and is linked to several negative health outcomes. Yet, little is known about the social epidemiology of BED, particularly in early adolescence. The objective of this study was to examine the associations between sociodemographic characteristics and BED and binge-eating behaviors in a large, national cohort of 10-14-year-old adolescents in the United States (U.S.) METHODS: We conducted a cross-sectional analysis of two-year follow-up data from the Adolescent Brain Cognitive Development (ABCD) Study (2018 - 2020) that included 10,197 early adolescents (10 - 14 years, mean 12 years) in the U.S. Multivariable logistic regression models were used to assess the associations between sociodemographic characteristics and BED and binge-eating behaviors, defined based on the Kiddie Schedule for Affective Disorders and Schizophrenia.

RESULTS

In this early adolescent sample (48.8% female, 54.0% White, 19.8% Latino/Hispanic, 16.1% Black, 5.4% Asian, 3.2% Native American, 1.5% Other), the prevalence of BED and binge-eating behaviors were 1.0% and 6.3%, respectively. Identifying as gay or bisexual (compared to heterosexual; adjusted odds ratio [AOR]: 2.25, 95% CI 1.01-5.01) and having a household income of less than $75,000 (AOR: 2.05, 95% CI: 1.21-3.46) were associated with greater odds of BED. Being male (AOR: 1.28, 95% CI: 1.06-1.55), of Native American (AOR: 1.60, 95% CI: 1.01-2.55) descent, having a household income less than $75,000 (AOR: 1.34, 95% CI: 1.08-1.65), or identifying as gay or bisexual (AOR for 'Yes' Response: 1.95, 95% CI: 1.31-2.91 and AOR for 'Maybe' Response: 1.81, 95% CI: 1.19-2.76) were all associated with higher odds of binge-eating behaviors.

CONCLUSION

Several sociodemographic variables showed significant associations with binge-eating behaviors, which can inform targeted screening, prevention, and education campaigns for BED among early adolescents.

Incidence and prevalence of eating disorders among active duty US military-dependent youth from 2016 to 2021

OBJECTIVE

The offspring of US military service members may be at increased risk for eating disorders. However, no epidemiological studies to date have evaluated eating disorder incidence rates and prevalence estimates among military-dependent youth.

METHOD

This retrospective cohort study examined eating disorder diagnoses in the military healthcare system (MHS) from 2016 through 2021. Active duty and national guard military-dependent youth, aged 10-17 years, who received care in the MHS via TRICARE Prime insurance, were identified by one or more ICD-10 codes indicative of an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, binge-eating disorder, and other-specified eating disorders).

RESULTS

During the 6-year surveillance period, 2534 dependents received incident diagnoses of eating disorders, with a crude overall incidence rate of 1.75 cases per 10,000 person-years. The most common diagnosis was other-specified eating disorder, followed by anorexia nervosa, bulimia nervosa, and binge-eating disorder. The crude annual incidence rate of all eating disorder diagnoses increased by nearly 65% from 2016 to 2021. Rates for all diagnoses were highest in 2020 and 2021. Period prevalence estimates were .08% for any eating disorder diagnosis, .01% for anorexia nervosa, .004% for bulimia nervosa, .004% for binge-eating disorder, and .06% for other-specified eating disorders.

DISCUSSION

The observed increase in eating disorder diagnoses during the surveillance period appeared to be driven by female dependents. More military dependents experienced a new-onset diagnosis during the COVID-19 pandemic compared to previous years. These findings highlight the need for eating disorder screening, identification, and treatment for dependents within the MHS.

PUBLIC SIGNIFICANCE STATEMENT

Children of US military service members may be at increased risk for eating disorders. Results indicate new-onset eating disorder cases increased 65% from 2016 to 2021, primarily among girls compared to boys. The most diagnosed and fastest growing diagnosis was other-specified eating disorder. Rates of anorexia nervosa increased following the COVID-19 pandemic. Findings highlight the need for eating disorder screening, identification, and treatment within the military healthcare system.

Comparison of prevalence and mental health problems across symptom frequency of self-reported symptoms of binge-eating disorder in a community sample of adolescents

OBJECTIVE

Binge-eating disorder (BED) and subthreshold BED (SBED) are prevalent in adults and associated with mental health problems including depression, non-suicidal self-injury, lower quality of life, and suicidality. There is solid evidence that binge-eating behaviors are also prevalent in adolescence, but knowledge about mental health in community adolescents with BED of different frequency thresholds is more limited. We aimed to investigate the prevalence and mental health problems associated with SBED of low frequency and/or limited duration compared with BED in a Danish community sample of adolescents.

METHODS

We included 2509 adolescents who completed the online survey of the 16-17-year follow-up of the Copenhagen Child Cohort (CCC2000), including items on BED symptoms approximating the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria, and items on mental health and quality of life.

RESULTS

The 1-year prevalence of SBED was 2.7% (95% confidence interval [CI]: 2.0%-3.3%) with a male:female ratio of 1:3.7; comparable to previous findings on BED in the same sample. SBED was also comparable to BED concerning cross-sectional associations with overall mental health problems, lower health-related quality of life, depressive symptoms, and suicidal ideation, whereas no associations were seen with non-suicidal self-injury after Holm-Bonferroni correction. In both groups, thoughts and behaviors concerning food and weight interfered significantly with daily life.

DISCUSSION

SBED and BED were equally prevalent in this adolescent community sample, and similarly associated with indicators of poor mental health. The findings indicate that community adolescents reporting symptoms approximating clinical criteria of BED need intervention irrespectively of symptom frequency or duration.

PUBLIC SIGNIFICANCE

This study adds knowledge to the field by comparing BED of low frequency and/or limited duration ("subthreshold BED," SBED) with full-syndrome BED in adolescents and showing that SBED in adolescence is both prevalent and associated with poor mental health to a similar extent as that of BED. Findings indicate that self-reported symptoms according to clinical criteria of SBED and BED alike constitute a public health problem and point to youngsters in need of intervention.

Hospitalization patterns for adolescents with eating disorders during COVID-19

PURPOSE

The purpose of this study was to examine differences in clinical characteristics and hospital length of stay (LOS) for adolescents with eating disorders (EDs) requiring medical stabilization during the pre-COVID-19 and COVID-19 time periods.

METHODS

Medical record data were abstracted for patients with EDs hospitalized for medical stabilization between 1/1/2019-2/29/2020 (pre-COVID-19) and 3/1/2020-12/31/2021 (during COVID-19). Patient demographics, clinical characteristics and LOS were compared between COVID-19 eras. Patients were categorized as boarding if they remained hospitalized ≥ 1 day after medical stabilization. Multivariate negative binomial linear regression models were performed to determine incidence rate ratios (IRR) and 95% confidence intervals (95% CI) for factors related to increased LOS.

RESULTS

Of the 467 admissions during this study, 120 were pre-COVID-19 and 347 were during COVID-19. Monthly admissions for EDs were higher during COVID-19 versus pre-COVID-19 (15.8 vs. 8.6, p = 0.001). On multivariate analysis, factors associated with increased LOS included admission during COVID-19 (IRR 1.27, 95% CI 1.15-1.40), p = 0.001), boarding (IRR 1.77, 95% CI 1.63-1.93, p = 0.001), public insurance (IRR 1.12, 95% CI 1.01-1.23, p = 0.032), nasogastric tube usage (IRR 1.62, 95% CI 1.48-1.76, p = 0.001), heart rate < 40 beats per minute (IRR 1.21, 95% CI 1.11-1.33, p = 0.001) and abnormal electrocardiogram (IRR 1.25, 95% CI 1.14-1.37, p = 0.001).

CONCLUSION

In addition to clinical factors, we found that admission during COVID-19, boarding, and public insurance were associated with increased LOS among patients with EDs. There is a need for greater availability of ED treatment centers to care for patients with EDs after medical stabilization.

Weight and disordered eating among adolescents from low-income backgrounds

Disordered eating affects youth from varying socioeconomic backgrounds; however, representation of youth from low-income backgrounds within disordered eating research has been limited. The aim of the current study was to examine the association between adolescent weight and disordered eating among a sample of youth from a low-income background and to examine specific socioenvironmental factors that might moderate this association. Adolescents ages 12-17 (N = 73) from a low-income background and their parents/guardians completed self-report questionnaires. Adolescent height and weight were objectively measured to calculate BMI z-score. Adolescent weight was significantly positively associated with global disordered eating (95 % CI [0.26, 0.54]), after controlling for sex. Parental weight concern moderated the association between weight and global disordered eating, F(4, 68) = 18.44, p < .01, such that the relation between adolescent zBMI and disordered eating was no longer significant at low levels of parental weight concern. Structured family meals moderated the association between weight and global disordered eating, F(4, 68) = 11.99, p < .01, such that more frequent meals weakened the association between adolescent zBMI and disordered eating. Findings suggest that higher weight is associated with greater levels of disordered eating among adolescents from a low-income background. In addition, lower levels of parental weight concern and more frequent family meals significantly buffered the association between weight and disordered eating in this at-risk, yet understudied population. Both parental weight concern and family meals present as factors within the family environment that may serve as targets for intervention.

Associations between household income and disordered eating differ across sex and racial identity in a population-based sample of adults

BACKGROUND

Most research on socioeconomic status (SES) and eating disorders (EDs) has focused on young White women. Consequently, little is known regarding how SES may relate to EDs/disordered eating in older adults, men, or people with different racial identities. We examined whether associations between SES and EDs/disordered eating differed across age, sex, and racial identity in a large, population-based sample spanning early-to-later adulthood.

METHODS

Analyses included 2797 women and 2781 men ages 18-65 (Mage  = 37.41, SD = 7.38) from the population-based Michigan State University Twin Registry. We first examined associations between SES and dimensional ED symptoms, binge eating (BE), and self-reported ED diagnoses across age and sex in the full sample. We then examined the impact of racial identity on associations by conducting within- and between-group analyses among Black and White participants.

RESULTS

In the full sample, lower SES was associated with significantly greater odds of BE and lifetime EDs in men, but not women, across adulthood. The association between lower SES and greater BE risk was stronger for Black men than for White men, though significant in both groups. Conversely, Black women showed a positive association between SES and dimensional ED symptoms that significantly differed from effects for Black men and White women.

CONCLUSIONS

Associations between socioeconomic disadvantage and EDs/disordered eating may be particularly robust for men in adulthood, especially men with a marginalized racial identity. Oppositely, Black women may encounter social pressures and minority stress in higher SES environments that could contribute to somewhat heightened ED risk.

PUBLIC SIGNIFICANCE

Little is known regarding how associations between socioeconomic status (SES) and eating disorders (EDs) may differ across age/sex or racial identity. We found lower SES was associated with greater odds of a lifetime ED or binge eating in men only, with a particularly strong association between lower SES and binge eating for Black men. Results highlight the importance of examining how SES-ED associations may differ across other aspects of identity.

Socioeconomic status and eating disorder prevalence: at the intersections of gender identity, sexual orientation, and race/ethnicity

BACKGROUND

Longstanding biases have fostered the erroneous notion that only those of higher socioeconomic status (SES) experience eating disorders (EDs); however, EDs present across all SES strata. Considering the dearth of ED research among those of lower SES, this study examined (1) the overall association between SES and ED prevalence, and (2) ED prevalence in the context of four relevant social identities (i.e. SES, gender identity, sexual orientation, and race/ethnicity) from an intersectional perspective, as unique combinations of multiple social identities may differentially influence risk.

METHODS

A sample of 120 891 undergraduate/graduate students from the Healthy Minds Study self-reported family SES with a single-item question, gender identity, sexual orientation, and race/ethnicity, and were screened for ED risk.

RESULTS

Participants of lower SES had 1.27 (95% CI 1.25-1.30) times greater prevalence of a positive ED screen than those of higher SES. Substantial heterogeneity was observed across the four social identities beyond the association with SES. For example, positive ED screens were particularly common among lower SES, Latinx, sexual minority cisgender men and women, with 52% of bisexual men and 52% of lesbian women of Latinx ethnicity and lower SES screening positive.

CONCLUSIONS

Although positive ED screens were more common among undergraduate/graduate students of lower SES, the particularly high ED risk reported by certain groups of lower SES with multiple minority identities reinforces the importance of investigating multi-layered constructs of identity when identifying groups at disproportionate risk.

A UK-wide survey of healthcare professionals' awareness, knowledge and skills of the impact of food insecurity on eating disorder treatment

OBJECTIVE

Food insecurity (FI) is associated with significant adverse effects on health and well-being and increasingly recognised as a global problem. The current study explored the impact of FI on eating disorder (ED) clinical practice in the UK, aiming to assess healthcare professionals' (HCPs) knowledge, skills and views on the topic of FI in their patients.

DESIGN

This study was an exploratory, mixed-methods, descriptive analysis of online survey data collected from ED HCPs in the UK between September and October 2022.

MEASURES

A 15-item survey with rating and open-ended questions was circulated to ED professional organisations in the UK. Descriptive statistics were used to summarise quantitative data, including perceived prevalence of FI in ED clinical practice and confidence in knowledge on the topic. Descriptive content analyses provided insight into perspectives on FI screening and aspects to be included in guidance and resources.

RESULTS

93 ED HCPs completed the survey (40.9 % psychologists). Findings demonstrated healthcare providers' limited knowledge on FI and its relation to EDs, while they increasingly perceive it in their patients, as well as a general lack of available resources on how to address FI in ED treatment. HCPs stressed the need for practical guidance and formal training for dealing with FI in their patients, as well as implementing routine screening.

CONCLUSION

These findings provide both important directions for future research and clinical applications related to screening, assessment, treatment and support of food-insecure patients with EDs.

Practical Considerations for Using the Eating Disorder Examination Interview with Adolescents

Approximately 35 years after its initial publication, the Eating Disorder Examination (EDE) remains one of the most widely used semi-structured interviews for assessing eating disorder diagnoses and symptomatology. Although the interview provides certain advantages over other common measurement approaches (ie, questionnaires), there are particular considerations regarding the EDE that warrant attention, including in its use with adolescents. The aims of this paper are therefore to: 1) provide a brief overview of the interview itself, as well as a description of its origin and underlying conceptual framework; 2) describe relevant factors for administering the interview with adolescents; 3) review potential limitations regarding use of the EDE with adolescents; 4) address considerations for using the EDE with pertinent subpopulations of adolescents who may experience distinct eating disorder symptoms and/or risk factors; and 5) discuss the integration of self-report questionnaires with the EDE. Advantages of using the EDE include the ability for interviewers to clarify complex concepts and mitigate inattentive responding, enhanced orientation to the interview timeframe to improve recall, increased diagnostic accuracy compared to questionnaires, and accounting for potentially salient external factors (eg, food/eating rules imposed by a parent/guardian). Limitations include more extensive training requirements, greater assessment burden, variable psychometric performance across subgroups, lack of items evaluating muscularity-oriented symptoms and avoidant/restrictive food intake disorder diagnostic criteria, and lack of explicit consideration for salient risk factors other than weight and shape concerns (eg, food insecurity).

Hospitalisation for mental health disorders in Australians with type 1 or type 2 diabetes

AIMS

To determine the burden and leading reasons for mental health hospitalisation among Australians with diabetes.

METHODS

We determined the incidence of hospitalisation for all mental health disorders in people with type 1 or type 2 diabetes of all ages by linking the National Diabetes Services Scheme to hospital admission datasets from 2010 to 2017. We compared those with type 2 diabetes aged 15 and above to the general population using excess hospitalisations per 100,000 person-years associated with diabetes.

RESULTS

Depressive disorders were the leading reason for mental health admission in Australians with diabetes, responsible for 6.09 (95% CI 5.78-6.42) and 7.05 (6.95-7.14) admissions per 1,000 person-years in those with type 1 and type 2 diabetes, respectively. When considering only one admission per person, mental health admission rates were up to 90% lower. Among males with type 2 diabetes, stress and adjustment disorders were the leading cause of excess admissions compared to the general population, while depressive disorders were the leading cause in females.

CONCLUSIONS

We found a substantial burden of psychiatric hospitalisations among Australians with diabetes, reinforcing the importance of mental health awareness among diabetes clinicians, and support by psychiatric teams for those with diabetes to prevent readmission.

Weighing in: qualitative explorations of weight restoration as recovery in anorexia nervosa

BACKGROUND

Anorexia Nervosa (AN) continues to capture the public's imagination, centered around physical appearance, particularly weight. Clinical conceptions of AN also emphasize weight. The objective of this study was to explore how individuals with lived AN experience thought about the role of weight in illness and recovery.

METHODS

The current study employed a grounded theory approach through qualitative inductive inquiry and analysis of 150 anonymous narratives, exploring firsthand experience of AN and recovery of adult individuals, based in the United States of America.

RESULTS

Individuals with AN histories contested intersecting popular cultural and medical presumptions of their health and illness positioned in weight. Respondents indicated that while weight does not measure recovery, it matters to recovery in unanticipated ways. Others' expectations for a low weight served as a gatekeeper to various forms of social and institutional support. Respondents felt that the weight obsessions of other people made it difficult to earn the illness legitimacy to access sufficient care.

CONCLUSIONS

Research findings bear implications for future AN research, advocacy, and clinical practice, as respondents pivot research emphasis from weight as a sociocultural motivation for AN, to weight as a sociocultural obstacle to AN recovery.

"I'm not alone": a qualitative report of experiences among parents of children with eating disorders attending virtual parent-led peer support groups

BACKGROUND

The treatment for children with eating disorders (EDs) requires extensive involvement of parents. The parents of children with EDs have voiced a need for greater support, including connecting with other parents with lived experience of caring for a child with an ED. We aimed to qualitatively explore parental experiences of these groups, including their benefits and areas for improvement.

METHODS

This study examined the delivery of four virtual parent-led peer support groups in Ontario, Canada for parents of children with EDs with approximately 10 parent participants per group and two parent facilitators leading each group. Parents (n = 44) were asked to attend 12 bi-weekly support group sessions over 6 months, and then complete an individual end-of-study qualitative interview. Interview data were analyzed using content analysis, following the qualitative description design.

RESULTS

Thirty-six parents completed the end-of-study qualitative interview. Participants shared their experiences and impressions related to the group's structure and content. Notable helpful aspects of the group included being able to receive support from those with similar experiences, access to education and resources about EDs, and being able to support others. Suggestions for improvements were made, which included organizing groups according to the child's ED diagnosis or duration of illness.

CONCLUSION

The findings indicate that this intervention is acceptable to parents and is perceived as helpful. Future research is needed to strengthen this support group model and to study its effects for parents in different settings and for parents of children with various EDs.

Subclinical binge eating symptoms in early adolescence and its preceding and concurrent factors: a population-based study

OBJECTIVE

Binge eating, loss of control eating and overeating often develop during late childhood or early adolescence. Understanding the presentation of binge eating as early as symptoms manifest and its preceding and concurrent factors is essential to hamper the development of eating disorders. This study examined the prevalence, concurrent and preceding factors (e.g. compensatory behaviors, emotional and behavioral problems) of subclinical binge eating symptoms in early adolescence.

METHODS

Data from the population-based Generation R Study were used (n = 3595). At 10 years and 14 years, preceding and concurrent factors including eating behaviors, body dissatisfaction, emotional and behavioral problems and body composition were assessed. At 14 years, 3595 adolescents self-reported on binge eating symptoms in the past 3 months and were categorized into four groups: no symptoms (n = 3143, 87.4%), overeating only (n = 121, 3.4%), loss of control (LOC) eating only (n = 252, 7.0%) or binge eating (i.e. both, n = 79, 2.2%).

RESULTS

In total, 452 (12.6%) young adolescents reported subclinical binge eating symptoms. Those who reported LOC eating and binge eating showed most compensatory behaviors (e.g. hide or throw away food, skipping meals). Concurrent emotional and behavioral problems, body dissatisfaction, more emotional-, restrained- and uncontrolled eating, and a higher BMI were associated with subclinical binge eating symptoms. Preceding self-reported emotional and behavioral problems, body dissatisfaction, more restrained eating and higher BMI (both fat mass and fat-free mass) at 10 years were associated with LOC eating and binge eating, but not with overeating.

DISCUSSION

Among young adolescents, subclinical binge eating symptoms were common. Considering the high prevalence of LOC eating, and the overlapping preceding and concurrent factors of LOC eating and binge eating compared to overeating, LOC eating seems to be a key symptom of binge eating in early adolescence.

What next for eating disorder genetics? Replacing myths with facts to sharpen our understanding

Substantial progress has been made in the understanding of anorexia nervosa (AN) and eating disorder (ED) genetics through the efforts of large-scale collaborative consortia, yielding the first genome-wide significant loci, AN-associated genes, and insights into metabo-psychiatric underpinnings of the disorders. However, the translatability, generalizability, and reach of these insights are hampered by an overly narrow focus in our research. In particular, stereotypes, myths, assumptions and misconceptions have resulted in incomplete or incorrect understandings of ED presentations and trajectories, and exclusion of certain patient groups from our studies. In this review, we aim to counteract these historical imbalances. Taking as our starting point the Academy for Eating Disorders (AED) Truth #5 "Eating disorders affect people of all genders, ages, races, ethnicities, body shapes and weights, sexual orientations, and socioeconomic statuses", we discuss what we do and do not know about the genetic underpinnings of EDs among people in each of these groups, and suggest strategies to design more inclusive studies. In the second half of our review, we outline broad strategic goals whereby ED researchers can expand the diversity, insights, and clinical translatability of their studies.

Emergency Department Utilization by Patients With Eating Disorders: A National Population-Based Study

Background There is a scarcity of national United States (U.S) data on emergency department (ED) utilization by patients with eating disorders. This study aims to determine the most common reasons for ED visits of patients with eating disorders, as well as baseline characteristics of patients who present due to eating disorders. Methods We obtained data from the Nationwide Emergency Department Sample (NEDS), the largest all-payer ED database in the United States. Each ED visit in NEDS 2018 can have only one "principal" diagnosis, which is the main reason for the visit and up to 34 "secondary" diagnoses. We abstracted data for all ED visits with "any" diagnosis of an eating disorder, using the ICD-10 code "F50". We highlighted the 10 most common "principal" diagnoses based on the organ system involved and the 10 most specific "principal" diagnoses for all ED visits by patients with any diagnosis of eating disorder. We then highlighted baseline characteristics of ED visits with a "principal" diagnosis of an eating disorder. Results There were a total of 56,901 ED visits for patients with eating disorders in 2018. Among these, 7,979 had an eating disorder as the "principal" diagnosis. Patients who visited the ED principally for eating disorders were more likely to be young females and came from higher-income households; about a third were admitted with 22.1 million U.S. dollars in aggregate ED charges. Mental disorders, and injuries and poisoning were the most common principal diagnosis by organ system categories, while eating disorders, major depression disorder (MDD), hypokalemia, and dehydration are common specific reasons for ED visits among patients with eating disorders. Conclusions Eating disorders, and its medical complications and psychiatric comorbidities such as MDD are common reasons for ED visits among patients with eating disorders. Management of the underlying eating disorder and their psychiatric comorbidities through a multidisciplinary approach in the outpatient setting is invaluable in reducing ED utilization by these patients.

Associations between parental socioeconomic-, family-, and sibling status and risk of eating disorders in offspring in a Danish national female cohort

OBJECTIVE

Studies on parental socioeconomic status (SES) and family risk factors for eating disorders (EDs) have yielded inconsistent results; however, several studies have identified high parental educational attainment as a risk factor. The aim was to evaluate associations of parental SES and family composition with anorexia nervosa (AN), bulimia nervosa (BN), and eating disorders not otherwise specified (EDNOS) in the offspring, adjusting for parental age and parental mental health.

METHODS

The cohort included women born in Denmark between January 1, 1989 and December 31, 2010, derived from Danish national registers. Each person was followed from their sixth birthday until onset of the disorder of interest or to December 31, 2016. Exposure variables were: childhood SES, defined as individually evaluated parental level of income, occupation, and education; sibling status; and family composition. Outcomes were: AN, BN, EDNOS, and major depressive disorder (MDD), included as a psychiatric comparison disorder. Risks were estimated using Cox proportional hazards.

RESULTS

High parental SES was associated with increased risk of especially AN, and less so BN and EDNOS, in offspring. In comparison, low SES was associated with a higher risk of MDD. No differences between maternal or paternal socioeconomic risk factors were found. Family composition and sibling status showed limited influence on ED risk.

DISCUSSION

SES shows opposite associations with AN than MDD, whereas associations with BN and EDNOS are intermediate. The socioeconomic backdrop of AN differs markedly from that reported in other psychiatric disorders. Whether that is due to genetic and/or environmental factors remains unknown.

PUBLIC SIGNIFICANCE STATEMENT

Parental socioeconomic background (SES) may influence eating disorders risk in offspring somewhat differently than other psychiatric disorders. In Denmark, higher parental SES was associated with increased risk of, particularly, anorexia nervosa (AN). Importantly AN does strike across the SES spectrum. We must ensure that individuals of all backgrounds have equal access to care and are equally likely to be detected and treated appropriately for eating disorders.

Internalization of Appearance Ideals and Not Religiosity Indirectly Impacts the Relationship Between Acculturation and Disordered Eating Risk in South and Southeast Asian Women Living in the United States

Objective

Studies that examine disordered eating in samples of Asian individuals living in the United States frequently combine all individuals of Asian descent into a single group, which can obscure important differences between groups and their experiences of acculturation. The goal of the present study was to establish the relation of acculturation, internalization of appearance ideals, and religiosity as predicting body dissatisfaction and disordered eating in women of South and Southeast Asian (SSEA) descent.

Method

Women of SSEA descent (N = 112) aged 18-51 years (M = 23.10, SD = 6.4) completed a battery of questionnaires that inquire about these variables. A path analysis was conducted with acculturation serving as the independent (exogenous) variable, religiosity and internalization of the thin ideal as mediators, and body dissatisfaction and disordered eating as dependent (endogenous) variables.

Results

Direct paths from acculturation to both body dissatisfaction and disordered eating were not significant. Thin ideal internalization completely accounted for the path from acculturation to both endogenous variables; whereas, religiosity did not significantly account for any indirect effect.

Discussion

For SSEA women, internalization of appearance ideals is a potentially greater risk factor for disordered eating than acculturation or religiosity. As this was an atemporal mediation analysis, more work needs to be done exploring predictors of internalization in this population and how that may impact the development of disordered eating.

Responding to "Terminal anorexia nervosa: three cases and proposed clinical characteristics"

The treatment of eating disorders raises many ethical debates given the pervasiveness with which this illness impacts individuals, especially as the length of time with the illness increases. A recent case study supported the appropriateness of pursuing medical aid in dying for individuals with eating disorders who wish to end their fight with their disorder. This correspondence raises concerns related to this controversial proposal as the current authors dispute that the use of medical aid in dying for individuals with eating disorders is ethically judicious or appropriate. Additionally, this correspondence highlights additional treatment implications that should be considered when trying to provide individuals with eating disorders with the best evidence-based care possible, with the goal of promoting steps toward recovery.

Estimated prevalence of eating disorders in Malaysia based on a diagnostic screen

Eating disorders (EDs) are debilitating health conditions and common across cultures. Recent reports suggest that about 14.0% of university students in Malaysia are at risk for developing an ED, and that prevalence may differ by ethnicity and gender. However, less is known about the prevalence of EDs in nonuniversity populations.

OBJECTIVE

The current study seeks to (1) estimate the prevalence of EDs and ED risk status among adults in Malaysia using an established diagnostic screen; (2) examine gender and ethnic differences between ED diagnostic/risk status groups; and (3) characterize the clinical profile of individuals who screen positive for an ED.

METHOD

We administered the Stanford-Washington University Eating Disorder Screen, an online ED screening tool, to adults in Malaysia in September 2020.

RESULTS

ED risk/diagnostic categories were assigned to 818 participants (ages 18-73 years) of which, 0.8% screened positive for anorexia nervosa, 1.4% for bulimia nervosa, 0.1% for binge-ED, 51.4% for other specified feeding or ED, and 4.8% for avoidant/restrictive food intake disorder. There was gender parity in the high risk and the overall ED categories. The point prevalence of positive eating pathology screening among Malays was significantly higher than Chinese but no different from Indians.

DISCUSSION

This is the first study to estimate the prevalence of EDs using a diagnostic screen in a population-based sample of Malaysians. It is concerning that over 50% of Malaysians reported symptoms of EDs. This study highlights the need to invest more resources in understanding and managing eating pathology in Malaysia.

PUBLIC SIGNIFICANCE

This study estimates the prevalence of EDs among adults in Malaysia using an online EDs screen. Over 50% of Malaysians report symptoms of EDs. The study highlights the need for more resources and funding to address this important public health issue through surveillance, prevention, and treatment of EDs in Malaysia.

A systematic review of sociodemographic reporting and representation in eating disorder psychotherapy treatment trials in the United States

OBJECTIVE

Eating disorders (EDs) were once conceptualized as primarily affecting affluent, White women, a misconception that informed research and practice for many years. Abundant evidence now discredits this stereotype, but it is unclear if prevailing "evidence-based" treatments have been evaluated in samples representative of the diversity of individuals affected by EDs. Our goal was to evaluate the reporting, inclusion, and analysis of sociodemographic variables in ED psychotherapeutic treatment randomized controlled trials (RCTs) in the US through 2020.

METHODS

We conducted a systematic review of ED psychotherapeutic treatment RCTs in the US and examined the reporting and inclusion of gender identity, age, race/ethnicity, sexual orientation, and socioeconomic status (SES) of enrolled participants, as well as recruitment methods, power analyses, and discussion of limitations and generalizability.

RESULTS

Our search yielded 58 studies meeting inclusion criteria dating back to 1985. Reporting was at times incomplete, absent, or centered on the racial/gender majority group. No studies reported gender diverse participants, and men and people of color were underrepresented generally, with differences noted across diagnoses. A minority of papers considered sociodemographic variables in analyses or acknowledged limitations related to sample characteristics. Some progress was made across the decades, with studies increasingly providing full racial and ethnic data, and more men included over time. Although racial and ethnic diversity improved somewhat, progress appeared to stall in the last decade.

DISCUSSION

We summarize findings, consider context and challenges for RCT researchers, and offer suggestions for researchers, journal editors, and reviewers on improving representation, reporting, and analytic practices.

PUBLIC SIGNIFICANCE

Randomized controlled trials of eating disorder psychotherapeutic treatment in the US are increasingly reporting full race/ethnicity data, but information on SES is inconsistent and sexual orientation absent. White women still comprise the overwhelming majority of participants, with few men and people of color, and no gender-diverse individuals. Findings underscore the need to improve reporting and increase representation to ensure evidence-based treatments are effective across and within diverse groups.

Patient perceptions of the relationship between food insecurity and eating disorder treatment: A qualitative exploration

INTRODUCTION

Independently, food insecurity (FI) and binge-spectrum eating disorders (B-ED) are widespread problems; moreover, FI is associated with elevated binge-eating symptoms. However, extant research has not explored how FI may contribute to the development of B-ED symptoms, nor potential impacts of FI on eating disorder treatment.

METHOD

This study aimed to qualitatively examine (1) mechanisms by which FI impacts B-ED development and maintenance, (2) effects of past and/or present FI on ED treatment, and (3) participant recommendations for addressing FI in future B-ED treatment. Fourteen individuals who completed B-ED treatment and endorsed FI completed a 30-min interview about their experiences.

RESULTS

Participants reported that FI contributed to binge eating by maintaining dietary restraint-binge-eating cycle and by leading them to use food as a coping mechanism or for emotional comfort, both in past and present situations. Present FI interfered with treatment, particularly with adhering to treatment recommendations and food purchasing choices, however, participants did not report any impact of past FI on B-ED treatment. Participants reported that rarely was FI addressed as part of treatment; most participants suggested that future treatments work to (1) assess and problem solve present FI to minimize interference and (2) assess and understand the influence of past FI on current symptoms to validate the function of behavior.

DISCUSSION

These findings provide qualitative support that FI may reinforce B-ED symptoms and present FI may interfere with treatment. This study emphasizes the need for assessment and consideration of FI as a factor when treating individuals with B-EDs.

A Plea for Diversity in Eating Disorders Research

Eating disorders (EDs) are often stereotyped as affecting the SWAG, that is, as affecting mostly skinny, White, affluent girls. Over the last decade, however, significant progress has been made toward increasing diversity in ED research. There is consensus that EDs affect individuals of all genders, ages, sexual orientations, ethnic, and socio-economic backgrounds, with recent studies exploring social determinants of ED etiology, ED presentation, and developing diversity-affirming ED assessments. This article provides a brief summary of current developments related to diversity as a research theme, and proposes different perspectives toward further improving diversity in ED research. Specifically, we argue for exploring the role of diversity in ED treatment settings and outcomes, for pursuing diversity-oriented research pro-actively rather than as a reaction to issues of under-representation, and for integrating diversity across different areas of medical education and trainings in psychotherapy. Limitations with respect to the paucity of research, and the link between diversity as a research theme and ED-related workforce diversity are discussed.
