Gender identity, race/ethnicity and eating pathology in a treatment-seeking community sample

Weight stigma and binge eating related to poorer perceptions of healthcare provider interaction quality in a community-based sample

BACKGROUND

Weight stigma refers to the social rejection, discrimination, and ideological devaluation of individuals because of body size and is a direct result of weight bias and anti-fat attitudes. Individuals with higher weight may be less likely to seek healthcare due to weight stigma, and if or when they do present for care, medical providers with weight bias may fail to provide high quality care. Little, however, is known about the intersectionality of weight stigma and perceptions of healthcare interactions as experienced by individuals who also binge eat.

METHODS

Community-based adults completed online self-report questionnaires regarding generalized weight stigma (Attitudes Towards Obese Persons1), healthcare interaction quality (Patient Perceptions of Healthcare Provider Interaction Quality; PPH), and disordered eating (Eating Disorder Examination-Questionnaire) via Amazon's Mechanical Turk platform. For this cross-sectional study, participants were categorized by the presence and absence of regular binge episodes. Pearson's correlations, T-tests, ANOVA/ANCOVA, and a multivariate regression were used to examine relationships among demographic variables, weight stigma, disordered eating, and the PPH.

RESULTS

Participants (N = 648) primarily identified as female (65.4%) and White, non-Hispanic (72.7%). Participants' average age and body mass index (BMI) were 37.5 (SD = 12.3) years old and 27.3 (SD = 6.9) kg/m2, respectively. Higher healthcare provider interaction quality ratings (PPH) were significantly related to lower BMI (r(648)=-0.098,p = 0.012), less weight stigma (r(648) = 0.149,p < 0.001), and identifying as a woman (t(514) = 2.09, p = 0.037, Cohen's d = 0.165) or White, non-Hispanic (t(646)=-2.73, p = 0.007, Cohen's d=-0.240). Participants reporting regular binge eating endorsed significantly worse perceptions of healthcare provider quality than those who did not, even after accounting for BMI, F(1, 645) = 8.42, p = 0.004, η2 = 0.013. A multivariate linear regression examining the PPH as dependent, and weight stigma and binge eating as independent, variable/s, was significant even after accounting for covariates (sex, race, BMI), F(95, 640) = 7.13,p < 0.001, R2 = 0.053 (small effect).

CONCLUSIONS

More negative experiences with healthcare providers was associated with worse weight stigma, higher BMI, regular binge eating and overall disordered eating, and for participants identifying as male or a Person of Color. These data have implications for non-clinical community populations and are particularly important as experiencing poorer quality of interactions with healthcare providers may decrease individuals' likelihood of seeking needed care for both disordered eating and health-related concerns.

Prevalence, characteristics, and correlates of probable avoidant/restrictive food intake disorder among adult respondents to the National Eating Disorders Association online screen: a cross-sectional study

BACKGROUND

Avoidant/restrictive food intake disorder (ARFID) is a serious, albeit under-researched, feeding or eating disorder. This exploratory study utilized data from adult respondents to the National Eating Disorders Association online eating disorder screen to validate items assessing the presence of ARFID and examine the prevalence, clinical characteristics, and correlates of a positive ARFID screen.

METHODS

Among 50,082 adult screen respondents between January 2022 and January 2023, the prevalence of a positive ARFID screen was calculated. Chi-square tests and t-tests compared demographics, eating disorder attitudes and behaviors, suicidal ideation, current eating disorder treatment status, and eating disorder treatment-seeking intentions between respondents with possible ARFID and other eating disorder diagnostic and risk categories. Clinical characteristics of respondents with possible ARFID were also examined.

RESULTS

2378 (4.7%) adult respondents screened positive for ARFID. Respondents with possible ARFID tended to be younger, male, and have lower household income, and were less likely to be White and more likely to be Hispanic/Latino than most other diagnostic/risk groups. They had lower weight/shape concerns and eating disorder behaviors than most other diagnoses and higher BMI than those with AN. 35% reported suicidal ideation, 47% reported intentions to seek treatment for an eating disorder, and 2% reported currently being in treatment. The most common clinical feature of ARFID was lack of interest in eating (80%), followed by food sensory avoidance (55%) and avoidance of food due to fear of aversive consequences (31%).

CONCLUSIONS

Findings from this study indicated that ARFID was prevalent among adult screen respondents and more common among individuals who were younger, male, non-White, Hispanic, and lower income relative to those with other eating disorders, at risk for an eating disorder, or at low risk. Individuals with possible ARFID frequently reported suicidal ideation and were rarely in treatment for an eating disorder. Further research is urgently needed to improve advances in the assessment and treatment of ARFID and improve access to care in order to prevent prolonged illness duration.

Prevalence, Characteristics, and Correlates of Avoidant/Restrictive Food Intake Disorder among Adult Respondents to the National Eating Disorders Association Online Screen: A Cross-Sectional Study

Background

Avoidant/restrictive food intake disorder (ARFID) is a serious, albeit under-researched, feeding or eating disorder. This exploratory study utilized data from adult respondents to the National Eating Disorders Association (NEDA) online eating disorder screen to validate items assessing the presence of ARFID and examine the prevalence, clinical characteristics, and correlates of a positive ARFID screen compared to other probable eating disorder/risk categories.

Methods

Among 47,705 adult screen respondents between January 2022 and January 2023, the prevalence of a positive ARFID screen was calculated. Chi-square tests and t-tests compared demographics, eating disorder attitudes and behaviors, suicidal ideation, current eating disorder treatment status, and eating disorder treatment-seeking intentions between respondents with possible ARFID and other eating disorder diagnostic and risk categories. Clinical characteristics of respondents with possible ARFID were also examined.

Results

2,378 (5.0%) adult respondents screened positive for ARFID. Respondents with possible ARFID tended to be younger, male, and have lower household income, and were less likely to be White and more likely to be Hispanic/Latino than most other diagnostic/risk groups. They had lower weight/shape concerns and eating disorder behaviors than all other diagnoses but higher BMI than those with AN. 35% reported suicidal ideation, 47% reported intentions to seek treatment for an eating disorder, and 2% reported currently being in treatment. The most common clinical feature of ARFID was lack of interest in eating (80%), followed by food sensory avoidance (55%) and avoidance of food due to fear of aversive consequences (31%).

Conclusions

Findings from this study indicated that ARFID was prevalent among adult screen respondents and more common among individuals who were younger, male, non-White, Hispanic, and lower income relative to those with other eating disorders or at risk for an eating disorder. Individuals with possible ARFID frequently reported suicidal ideation and were rarely in treatment for an eating disorder. Further research is urgently needed to improve advances in the assessment and treatment of ARFID and improve access to care in order to prevent prolonged illness duration.

Loss-of-Control-Eating Mediates the Relationship between Cannabis-Related Problems and Eating Pathology

The prevalence of eating pathology among college students has increased significantly in recent years. This coincides with increases in the use of cannabis, both nationally, but also among college students. Problematic cannabis use has been linked to eating pathology in prior research. Research also shows that cannabis may affect appetitive drives linked to food consumption. The current study tested the hypothesis that the association between problem cannabis use and eating pathology was mediated by greater loss of control eating. Cross-sectional data were collected from a sample of 805 college student cannabis users at a large Southeastern university in the U.S. The sample were primarily Caucasian (76%) and female (65.22%) with an average age of 20.15 (SD = 3.91). Participants completed surveys assessing eating outcomes (loss of control eating and eating pathology), cannabis use, and cannabis-related problems. The analysis used an observed variable path model. After controlling for cannabis use, cannabis-related problems were indirectly linked to eating pathology via loss of control eating (B = 0.109, SE = 0.025, p < .001), supporting the primary hypothesis. The direct relationship between cannabis-related problems and eating pathology was fully accounted for (B = 0.010, SE = 0.028, p = .724) by the indirect effect of loss of control eating. These data suggest that the association between problematic forms of cannabis use and eating pathology may be due to the association between cannabis problems and loss of control eating. While this may be due to changes in appetite and food evaluation as a function of more problematic use patterns, it may also be that individuals with problematic cannabis use have more problematic eating patterns due to deficits in adaptive coping strategies. Future research should seek to parse out these different potential explanations.

Risk factors for eating disorders: findings from a rapid review

BACKGROUND

Risk factors represent a range of complex variables associated with the onset, development, and course of eating disorders. Understanding these risk factors is vital for the refinement of aetiological models, which may inform the development of targeted, evidence-based prevention, early intervention, and treatment programs. This Rapid Review aimed to identify and summarise research studies conducted within the last 12 years, focusing on risk factors associated with eating disorders.

METHODS

The current review forms part of a series of Rapid Reviews to be published in a special issue in the Journal of Eating Disorders, funded by the Australian Government to inform the development of the National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2021, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, or population studies). Data pertaining to risk factors for eating disorders were synthesised and outlined in the current paper.

RESULTS

A total of 284 studies were included. The findings were divided into nine main categories: (1) genetics, (2) gastrointestinal microbiota and autoimmune reactions, (3) childhood and early adolescent exposures, (4) personality traits and comorbid mental health conditions, (5) gender, (6) socio-economic status, (7) ethnic minority, (8) body image and social influence, and (9) elite sports. A substantial amount of research exists supporting the role of inherited genetic risk in the development of eating disorders, with biological risk factors, such as the role of gut microbiota in dysregulation of appetite, an area of emerging evidence. Abuse, trauma and childhood obesity are strongly linked to eating disorders, however less conclusive evidence exists regarding developmental factors such as role of in-utero exposure to hormones. Comorbidities between eating disorders and mental health disorders, including personality and mood disorders, have been found to increase the severity of eating disorder symptomatology. Higher education attainment, body image-related factors, and use of appearance-focused social media are also associated with increased risk of eating disorder symptoms.

CONCLUSION

Eating disorders are associated with multiple risk factors. An extensive amount of research has been conducted in the field; however, further studies are required to assess the causal nature of the risk factors identified in the current review. This will assist in understanding the sequelae of eating disorder development and in turn allow for enhancement of existing interventions and ultimately improved outcomes for individuals.

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.
