Accelerating Progress in Eating Disorders Prevention: A Call for Policy Translation Research and Training

Something, everything, and anything more than nothing: stories of school-based prevention of body image concerns and eating disorders in young people

Much work has been done to promote the development of positive body image in schools. This paper aims to tell some stories from the past 35 years of work in this field that illuminate important issues in developing, evaluating, and disseminating programs, and in removing policies and practices that could trigger weight stigma and body shame or disordered eating attitudes and behaviours. The need for, goals of, and approaches to body image programs, problematic activities we have 'good enough' evidence to avoid, and next steps for advocacy, research, and action are explored as we celebrate how far we've come and have hope for the future.

Prevention of eating disorders: 2023 in review

This review of 16 prevention-related publications in Eating Disorders during 2022 is framed by three models: (1) Mental Health Intervention Spectrum: health promotion → types of prevention → case identification/referral → treatment; (2) the prevention cycle: rationale and theory, shaped by critical reviews → clarifying risk and protective factors → program innovation and feasibility studies → efficacy and effectiveness research → program dissemination; and (3) definitions of and links between disordered eating (DE) and eating disorders (EDs). Seven articles fell into the category of prevention rationale (including screening studies) and relevant reviews, while nine articles addressed correlates of/risk factors (RFs) for various aspects of DE and EDs. One implication of the 16 articles reviewed is that RF research toward construction of selective and indicated prevention programs for an expanding array of diverse at-risk groups needs to address, from a nuanced, intersectional framework, a broad range of factors beyond negative body image and internalization of beauty ideals. Another implication is that, to expand and improve current and forthcoming prevention programs, and to shape effective advocacy for prevention-oriented social policy, the field in general and Eating Disorders in particular need more scholarship in the form of critical reviews and meta-analyses; protective factor research; prevention program development and multi-stage evaluation; and case studies of multi-step activism at the local, state (province, region), and national levels.

Disordered eating prevention: Co-designing a brief intervention for use in Community Child Health Services

Dietary habits established in childhood, often persist into adulthood highlighting the importance of early intervention. However, limited interventions exist promoting "how" to establish healthful eating behaviors in children. To create impactful interventions, it is important they are based on evidence and co-designed with end-users. Fifteen child health nurses participated in this co-design study, underpinned by the Knowledge to Action Framework. Child health nurses reviewed evidence-based statements and then workshopped practical strategies. Findings from the co-design sessions were used to inform the development of a preventive intervention. The study has important health marketing implications for conducting co-design with child health nurses.

Why "mealtime chatter matters": A process evaluation of a preventive health brief intervention

How parents communicate about food is important for building children's emotional relationships with food. "Mealtime Chatter Matters" (MCM) is an evidence-informed brief intervention providing behavioral strategies for parents focusing on positive communication at mealtimes. This process study explored parents' experiences of the brief intervention. Nine mothers participated in interviews, followed by a qualitative inductive analysis. Findings revealed the strengths and weaknesses of MCM and critical reflections of participants' experiences that can be used to inform future program strategies. This study has important health marketing implications for developing preventive health resources and indicates that future research on mealtime communication is warranted.

Examining the association of structural stigmas with body image-related outcomes among sexual minority individuals

Sexual minority individuals display heightened body image disturbance, which is associated with negative health outcomes. Structural stigmas are associated with negative health outcomes among sexual minority individuals, but the association between structural stigmas and body image is not understood. Using a linear regression approach, we examined how U.S. state-level structural racism and structural sexual minority stigma were associated with body image-related outcomes including eating pathology, appearance and/or performance-enhancing drug (APED) misuse, and dysmorphic concern. Participants were 942 cisgender sexual minority individuals ages 18-30, with approximately equal representation among non-Hispanic/Latinx White, Black, Asian, and Hispanic/Latinx individuals. There was not a significant main effect of state-level structural sexual minority stigma on body image-related outcomes. In states with higher structural racism, Hispanic/Latinx participants endorsed higher APED misuse, and this interaction was not significant among non-Hispanic/Latinx White individuals. This pattern was not found among Black or Asian participants, nor was it replicated for dysmorphic concern or eating pathology. Findings suggest that reducing exposure to structural racism could reduce APED misuse among Hispanic/Latinx individuals.

Population-level policy recommendations for the prevention of disordered weight control behaviors: A scoping review

OBJECTIVE

The aim of this scoping review was to identify recommendations and gaps in knowledge surrounding the prevention of disordered weight control behaviors (DWCBs) through policy.

METHOD

A search was conducted in several databases to identify English language articles that described an active policy, recommendation, guideline, or educational curriculum that could be implemented by governments or regulatory bodies to prevent DWCBs or related constructs (e.g., weight stigma, body dissatisfaction). Two researchers independently screened articles with oversight from a third researcher. Data were extracted from the final sample (n = 65) and analyzed qualitatively across all articles and within the domains of education, public policy, public health, industry regulation, and media.

RESULTS

Only a single empirical evaluation of an implemented policy to reduce DWCBs was identified. Over one-third of articles proposed recommendations relating to industry regulation and media (n = 24, 36.9%), followed by education (n = 21, 32.3%), public policy (n = 19, 29.2%), and public health (n = 10, 15.4%). Recommendations included school-based changes to curricula, staff training, and anti-bullying policies; legislation to ban weight discrimination; policies informed by strategic science; collaboration with researchers from other fields; de-emphasizing weight in health communications; diversifying body sizes and limiting modified images in media; and restricting the sale of weight-loss supplements.

DISCUSSION

The findings of this review highlight gaps in empirically evaluated policies to reduce DWCBs but also promising policy recommendations across several domains. Although some policy recommendations were supported by empirical evidence, others were primarily based on experts' knowledge, highlighting the need for greater research on population-level DWCBs prevention through policy.

PUBLIC SIGNIFICANCE

Our scoping review of the evidence on policies for the prevention of disordered weight control behaviors identified several recommendations across the domains of education, public policy, public health, and industry regulation and media. Although few empirical investigations of implemented policies have been conducted, expert recommendations for policies to prevent disordered weight control behaviors among populations are plentiful and warrant future consideration by researchers and policymakers alike.

Examining the feasibility of a brief parent intervention designed to promote positive food communication with infants

BACKGROUND

Few prevention interventions exist focusing on supporting parents to use positive food communication at mealtimes, for the prevention of disordered eating. "Mealtime chatter matters (MCM)" is a brief intervention designed for parents of infants. The intervention was designed in collaboration with child health nurses (CHNs) to be embedded into usual care. The overall aim of this study was to test the feasibility of the intervention through examining the acceptability of the MCM content and resources and the potential impact of the intervention on parents.

METHODS

This pilot study utilised a mixed methods approach and took place within a regional child health service in Queensland, Australia (October 2021 to June 2022). Participants were parents of infants attending child health education groups and CHNs. The intervention consisted of a brief education session (including accompanying resources), facilitated by a Paediatric Dietitian. The acceptability of MCM content and resources was assessed by both parents and CHNs via self-reported questionnaires and the potential impact on parents assessed via pre-/post-self-reported questionnaires.

RESULTS

Forty-six parents of infants (aged < 8 months) and six CHNs who hosted the intervention and observed the program's delivery participated in the study. MCM content and resources were highly acceptable to parents and CHNs, as both qualitative and quantitative data concurred. How the program may have potentially impacted parenting practices was unclear from the survey results and further investigation is required to better understand these. Tangible lessons and opportunities to further test this intervention were clear from current results.

CONCLUSION

Overall, MCM was acceptable to both parents and CHNs, with the content and resources both being highly valued. Parents reported the content to be informative and engaging and CHNs were keen to have such an intervention available in the future. However, further modification and testing is required of MCM. This feasibility study is an essential first step in supporting parents and CHNs to access an evidence-based intervention with the aim of preventing disordered eating.

Open Science in eating disorders: Using current evidence to inspire a plan for increasing the transparency of our research

OBJECTIVE

There is increasing consensus that open science practices improve the transparency and quality of clinical science. However, several barriers impede the implementation of these practices at the individual, institutional, and field levels; understanding and addressing these barriers is critical to promoting targeted efforts in increasing effective uptake of open science.

METHODS

Within this research forum, we drew from publicly available online information sources to identify initial characterizations of researchers engaged in several types of open science practices in the field of eating disorders. We use these observations to discuss potential barriers and recommendations for next steps in the promotion of these practices.

RESULTS

Data from online open science repositories suggest that individuals using these publishing approaches with pre-prints and articles with eating-disorder-relevant content are predominantly non-male gender identifying, early to mid-career stage, and are more likely to be European-, United States-, or Canada-based.

DISCUSSION

We outline recommendations for tangible ways that the eating disorder field can support broad, increased uptake of open science practices, including supporting initiatives to increase knowledge and correct misconceptions; and prioritizing the development and accessibility of open science resources.

PUBLIC SIGNIFICANCE STATEMENT

The use of open science practices has the potential to increase the transparency and quality of clinical science. This Forum uses publicly sourced online data to characterize researchers engaged in open science practices in the field of eating disorders. These observations provide an important framework from which to discuss potential barriers to open science and recommendations for next steps in the promotion of these practices.

Prevention of eating disorders: 2022 in review

This review of 17 prevention-related publications in Eating Disorders during 2022 is framed by three models: (1) Mental Health Intervention Spectrum: health promotion ➔ types of prevention ➔ case identification/referral ➔ treatment; (2) the prevention cycle: rationale and theory, shaped by critical reviews ➔ clarifying risk and protective factors ➔ program innovation and feasibility studies ➔ efficacy and effectiveness research ➔ program dissemination; and (3) definitions of and links between disordered eating (DE) and eating disorders (EDs). Five articles fell into the category of prevention rationale, theory, and critical analyses, while seven articles addressed risk factors (RFs) for various aspects of DE. Eating Disorders also published two pilot studies, two prevention efficacy trials, and one effectiveness study in 2022. One implication of the 17 articles reviewed is that RF research toward construction of selective and indicated prevention programs for diverse at-risk groups should address a broad range of factors beyond negative body image and internalization of beauty ideals. Another implication is that, to expand and improve current and forthcoming prevention programs, and to shape effective advocacy for prevention-oriented social policy, the field in general and Eating Disorders in particular need more scholarship in the form of critical reviews and meta-analyses, protective factor research, and case studies of multi-step activism at the local, state (province, region), and national levels.

40 years of research on eating disorders in domain-specific journals: Bibliometrics, network analysis, and topic modeling

Previous studies have used a query-based approach to search and gather scientific literature. Instead, the current study focused on domain-specific journals in the field of eating disorders. A total of 8651 documents (since 1981 to 2020), from which 7899 had an abstract, were retrieved from: International Journal of Eating Disorders (n = 4185, 48.38%), Eating and Weight Disorders (n = 1540, 17.80%), European Eating Disorders Review (n = 1461, 16.88%), Eating Disorders (n = 1072, 12.39%), and Journal of Eating Disorders (n = 393, 4.54%). To analyze these data, diverse methodologies were employed: bibliometrics (to identify top cited documents), network analysis (to identify the most representative scholars and collaboration networks), and topic modeling (to retrieve major topics using text mining, natural language processing, and machine learning algorithms). The results showed that the most cited documents were related to instruments used for the screening and evaluation of eating disorders, followed by review articles related to the epidemiology, course and outcome of eating disorders. Network analysis identified well-known scholars in the field, as well as their collaboration networks. Finally, topic modeling identified 10 major topics whereas a time series analysis of these topics identified relevant historical shifts. This study discusses the results in terms of future opportunities in the field of eating disorders.

Cost-Effectiveness of 5 Public Health Approaches to Prevent Eating Disorders

INTRODUCTION

Eating disorders cause suffering and a high risk of death. Accelerating the translation of research into implementation will require intervention cost-effectiveness estimates. The objective of this study was to estimate the cost-effectiveness of 5 public health approaches to preventing eating disorders among adolescents and young adults.

METHODS

Using data from 2001 to 2017, the authors developed a microsimulation model of a closed cohort starting at the age of 10 years and ending at 40 years. In 2021, an analysis was conducted of 5 primary and secondary prevention strategies for eating disorders: school-based screening, primary care‒based screening, school-based universal prevention, excise tax on over-the-counter diet pills, and restriction on youth purchase of over-the-counter diet pills. The authors estimated the reduction in years lived with eating disorders and the increase in quality-adjusted life-years. Intervention costs and net monetary benefit were estimated using a threshold of $100,000/quality-adjusted life year.

RESULTS

All the 5 interventions were estimated to be cost-saving compared with the current practice. Discounted per person cost savings (over the 30-year analytic time horizon) ranged from $63 (clinic screening) to $1,102 (school-based universal prevention). Excluding caregiver costs for binge eating disorder and otherwise specified feeding and eating disorders substantially reduced cost savings (e.g., from $1,102 to $149 for the school-based intervention).

CONCLUSIONS

A range of public health strategies to reduce the societal burden of eating disorders are likely cost saving. Universal prevention interventions that promote healthy nutrition, physical activity, and media use behaviors without introducing weight stigma may prevent additional negative health outcomes, such as excess weight gain.

Addressing eating disorders through legislation: The Israeli 'Models' Law'-process, enactment, and dilemmas

Preventing the onset of eating disorders and disordered eating pathology is crucial. While these conditions have a multi-factorial etiology, socio-cultural norms, particularly the media, contribute greatly. Policy and legislative action are warranted to change harmful media images. To the best of our knowledge, Israel was the first country to tackle the problem of unrealistic and unhealthy images in the media through legislation by initiating and passing an innovative law. The "Knesset," the Israeli Parliament, voted in December 2012 to pass new legislation that forbids the appearance of underweight models (BMI of 18.5 or less) in commercial advertising. The law further requires that if a graphic editing program has been used to reduce the dimensions of a model in advertising photographs, this fact must be clearly indicated. The purpose of this article is to describe the law; the process and obstacles to creating and passing the law in the Knesset; national and international reactions to this Israeli law; and the challenges of implementing (enacting and enforcing) this law in Israel. Given that other countries are implementing similar policies, additional legal approaches are described, including ideas for further research on how to enact, enforce, and evaluate the impact of such laws.

Work Addiction and Depression, Anxiety, and Stress: the Mediating Role of Food Addiction Among Lebanese Young Adult Workers

Work addiction is considered a public health concern, as it can lead to negative and harmful health outcomes. However, patterns leading from work addiction to mental health concerns remain so far largely unknown and under-studied. We aimed to verify whether the relationship between work addiction and psychological distress (i.e., depression, anxiety, and stress) is mediated by food addiction among young adult workers in the context of Lebanese culture. The second objective was to validate the Arabic version of the Bergen Work Addiction Scale (BWAS). The online cross-sectional survey was conducted among 1268 Lebanese young adult workers (65.1% females, mean age 26.18 years) using the Bergen Work Addiction Scale, the Depression Anxiety and Stress Scale, the Yale Food Addiction Scale, and the Three-Factor Eating Questionnaire. The PROCESS SPSS Macro version 3.4, model four, was used to compute the mediation analysis. Findings revealed that 175 (13.8%) were presented as work-addicted individuals, and 226 (17.8%) exhibited addictive-like eating behaviors. Bivariate analyses showed that higher degree of work addiction and food addiction was significantly associated with higher levels of depression, anxiety, and stress. The results of the mediation analysis showed that the association between work addiction and depression, anxiety, and stress was mediated by food addiction. In light of our findings, we cautiously suggest that the link of work addiction to psychological distress via food addiction implies that strategies targeting food addiction might mitigate the harmful effects of work addiction on workers' mental health.

Prevention of eating disorders: 2021 in review

This review of 19 prevention-related publications in Eating Disorders during 2021 is framed by four models: (1) Mental Health Intervention Spectrum: health promotion → types of prevention → case identification/referral → treatment; (2) the prevention cycle: rationale and theory, shaped by critical reviews → clarifying risk and protective factors → program innovation and feasibility studies → efficacy and effectiveness research → program dissemination; (3) links between disordered eating (DE) and eating disorders (EDs); and (4) Kraemer and Jacobi's criteria for variable, causal risk factors (RFs). Twelve articles demonstrated the strengths and limitations of cross-sectional investigations of RFs for DE and EDs: five explored the role of trauma in activating genetic and psychological RFs (e.g., anxiety and experiential avoidance), while five suggest other variables meriting further evaluation: ergogenic supplement use, "feeling fat," internalized weight bias, food insecurity, and compulsive exercising. One article presents a pilot program that reduced risk factors in a high-risk group: professional ballerinas. Implications of the absence of efficacy, effectiveness, dissemination, and advocacy studies, along with the need to develop tailored programs for various high-risk groups, are discussed.

Digging up the dirt on "clean" dietary labels: Public health considerations and opportunities for increased Federal oversight

BACKGROUND

"Clean" dietary labels are often viewed by consumers as referencing products that are minimally processed, without additives, preservatives, artificial colors, or ingredients, but may also be interpreted as vegan, gluten-free, dairy-free, "real," or "natural." Although the "clean" diet trend continues to grow in popularity, there is a lack of consensus regarding the definition and use of this terminology with a corresponding lack of regulation for such labels in the United States.

METHOD

This multidisciplinary scoping review examines the public health implications of the "clean" label trend and the legal and policy landscape for regulation. We report on findings from case law and legal research generated through the Westlaw database and from the U.S. Food and Drug Administration (FDA) enforcement actions and website documents to discuss options for federal- and state-level intervention to mitigate harm.

RESULTS

One feasible avenue for change is for the FDA to provide industry guidance, disseminate public statements to debunk myths, and enforce labeling statutes to police deceptive "clean" labeling claims. We also suggest consumer-protection litigation and state-level litigation via attorneys general as alternative actions to combat the abundant misinformation associated with "clean" diets and labels.

DISCUSSION

Although the FDA has taken some enforcement actions, these efforts are insufficient given the proliferation of "clean" label products in the marketplace and the potential for adverse impacts on public health including increased risk for disordered eating. The current unregulated, undefined landscape for "clean" dietary labels thus requires urgent action by federal authorities and state attorneys general.

Body image and internalization of appearance ideals in Black women: An update and call for culturally-sensitive research

Extant research on body image supports sociocultural theories emphasizing the internalization of societal pressures to attain the thin-ideal, as well as other White or Eurocentric ideals that are predominant in mainstream media. While earlier research suggests that Black women are less likely to report body dissatisfaction and thin-ideal internalization compared to women of other racial backgrounds, recent studies argue that most measures of body image and appearance ideals may not be accurate assessments of body dissatisfaction for this population. In this paper, we summarize the literature over the past two decades on body image and appearance ideals among cisgender Black girls and women and discuss the applications of well-established sociocultural theories of body dissatisfaction. We additionally highlight existing gaps in culturally-sensitive theory and assessment tools and consider the benefits of applying intersectionality-informed research. We lastly propose future directions in research, assessment, and intervention to develop more culturally-sensitive approaches to identifying, assessing, and addressing body dissatisfaction among Black girls and women. This paper encourages researchers to apply culturally-sensitive and intersectionality-informed theory to improve efforts in assessing early warning signs of body dissatisfaction and developing effective interventions for this population.

Eating Disorders Screening Tools: The Psychometric Properties of the Persian version of Eating Attitude Test

Background:

Screening for eating disorders via reliable instruments is of high importance for clinical and preventive purposes. Examining the psychometric properties of tools in societies with differing dynamics can help with their external validity. This research specifically aimed at standardization and validation of the eating attitude test (EAT-16) in Iran.

Methods:

The Persian version of the EAT-16 was produced through forward translation, reconciliation, and back translation. The current research design was descriptive cross-sectional (factor analysis). A total of 302 nonclinical students were selected through the convenience sampling method and completed a set of questionnaires. The questionnaires included, the EAT-16, eating beliefs questionnaire-18 (EBQ-18), difficulties in emotion regulation scale-16 (DERS-16), weight efficacy lifestyle questionnaire-short form, self-esteem scale, and self-compassion scale short-form. The construct validity of the EAT-16 was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test–retest reliability (2 weeks’ interval) were used to evaluate the reliability. Data analysis was conducted using LISREL (version 8.8) and SSPS (version 22) software.

Results:

EAT-16 and subscales were found to be valid and reliable, with good internal consistency and good, test–retest reliability in a non-clinical sample. In terms of convergent validity, EAT-16 and subscales showed a positive correlation with the selfreport measures of EBQ-18 and DERS-16. EAT-16 and subscales showed a negative correlation with self-compassion, self-esteem and eating self-efficacy., Therefore, it demonstrated divergent validity with these constructs. The results of this study support the EAT-16 four-factor model.

Conclusions:

The EAT-16 showed good validity and reliability and could be useful in assessing eating disorders in Iranian populations. The EAT-16 is an efficient instrument that is suitable for screening purposes in the nonclinical samples.

Assessment of eating disorder psychopathology: The psychometric properties of the Persian version of the Eating Disorder Examination Questionnaire Short Form

BACKGROUND

Eating disorders are complicated health problems that affect both the body and the mind. Eating disorders pose a serious challenge to mental health services because of their often chronic pathway. The current study was done to determine the psychometric properties of the Eating Disorder Examination Questionnaire Short Form (EDE-QS).

MATERIALS AND METHODS

Persian version of the EDE-QS was produced through forward-translation, reconciliation, and back-translation. The design of this research was cross- sectional. A sample of 302 Tehran university's students in 2019-2020 was selected through convenience sampling method and completed a set of questionnaires, including the EDE-QS, Eating Attitude Test (EAT-16), Eating Beliefs Questionnaire-18 (EBQ-18), Self-Esteem Scale (SES), and Self-Compassion Scale (SCS) Short Form. The construct validity of the EDE-QS was assessed using confirmatory factor analysis and divergent and convergent validity. Internal Consistency and test-retest reliability were conducted to evaluate the reliability. Data analysis was conducted using SPSS (version 22) software and LISREL (version 8.8).

RESULTS

EDE-QS was found to be valid and reliable measures, with good internal consistency and good test-retest reliability among students. Cronbach's alpha coefficient for the whole of scale was 0.85. Intraclass correlation coefficient for the whole of scale was 0.90. In terms of convergent validity, EDE-QS showed a significant positive correlation with self-report measures of EAT-16 and EBQ-18 (P < 05). EDE-QS showed a negative correlation with self-compassion and self-esteem, thus demonstrated a good divergent validity (P < 05). The results of this study also provide support for the one-factor model of the EDE-QS (root mean square error of approximation = 0.08, Normed Fit Index [NFI] = 0.90, Incremental Fit Index = 0.92, non-NFI = 0.90, and Comparative Fit Index = 0.92).

CONCLUSION

The EDE-QS showed good validity and reliability and could be useful in assessing eating disorder psychopathology in a nonclinical population of students. The EDE-QS shows notable promise as a measure for use in eating disorder research and clinical settings.

Online interventions to prevent mental health problems implemented in school settings: the perspectives from key stakeholders in Austria and Spain

BACKGROUND

Schools are key settings for delivering mental illness prevention in adolescents. Data on stakeholders' attitudes and factors relevant for the implementation of Internet-based prevention programmes are scarce.

METHODS

Stakeholders in the school setting from Austria and Spain were consulted. Potential facilitators (e.g. teachers and school psychologists) completed an online questionnaire (N=50), policy makers (e.g. representatives of the ministry of education and health professional associations) participated in semi-structured interviews (N=9) and pupils (N=29, 14-19 years) participated in focus groups. Thematic analysis was used to identify experiences with, attitudes and needs towards Internet-based prevention programmes, underserved groups, as well as barriers and facilitators for reach, adoption, implementation and maintenance.

RESULTS

Experiences with Internet-based prevention programmes were low across all stakeholder groups. Better reach of the target groups was seen as main advantage whereas lack of personal contact, privacy concerns, risk for misuse and potential stigmatization when implemented during school hours were regarded as disadvantages. Relevant needs towards Internet-based programmes involved attributes of the development process, general requirements for safety and performance, presentation of content, media/tools and contact options of online programmes. Positive attitudes of school staff, low effort for schools and compatibility to schools' curriculum were seen as key factors for successful adoption and implementation. A sound implementation of the programme in the school routine and continued improvement could facilitate maintenance of online prevention initiatives in schools.

CONCLUSIONS

Attitudes towards Internet-based mental illness prevention programmes in school settings are positive across all stakeholder groups. However, especially safety concerns have to be considered.

Promoting Confident Body, Confident Child in community child health: A mixed-methods implementation study

OBJECTIVE

To evaluate population-level implementation of Confident Body, Confident Child (CBCC); an evidence-based program providing parenting strategies to promote healthy eating, physical activity and body satisfaction in children aged 2-6 years; with community child health nurses (CHNs).

METHODS

This study utilised an implementation-effectiveness hybrid design, with dual focus on assessing: (a) CBCC implementation into Child Health Centres at a regional health service in Queensland, Australia (process evaluation); and (b) CBCC's effect on CHNs' knowledge and attitudes (outcomes evaluation). Process (CBCC reach, dose, fidelity) and outcome data (CHN knowledge of child body image; and attitudes towards higher body weights) were collected during implementation, and pre- and post-intervention delivery to CHNs, respectively.

RESULTS

Twenty-six CHNs (all female; mean age 52.7 ± 9.5 years) participated in the study by attending a 1-day CBCC training workshop and completing demographic and outcome surveys. Process evaluation found that CBCC was implemented as planned and reached 56% of CHNs across the health service. Outcome evaluation showed small but non-significant improvements in CHN knowledge (P = .077) and attitudes towards overweight (using Anti-Fat Attitudes scale; significant improvements on willpower sub-scale only (P < .05)).

DISCUSSION

This is the first study to evaluate population-wide CBCC implementation in a real-world health service setting with CHNs. Findings highlight the potential for using pragmatic, implementation-focused methodologies to translate preventive eating disorder programs into community child health services.

Looking to the future: Priorities for translating research to impact in the field of appearance and body image

The field of body image and appearance research and practice is progressing; however, there is still work to be done to ensure broad societal impact. This article consolidates reflections from a range of established and early career experts in the field of appearance and body image, with a focus on stimulating and guiding future agenda setting and translation from research to impact. We conducted a thematic analysis of transcripts from nine recorded 5-minute presentations, delivered by researchers and clinicians as part of a special invited presentation session at a biennial international conference, 'Appearance Matters,' in the UK. Four themes were identified: Moving Beyond the Individual; Consolidation and Collaboration; Commitment to Implementation; and Positive and Protective Frameworks. These themes are discussed alongside recommendations for researchers and practitioners working in these fields to advance research, advocacy, and impact outside of academia.

The Impact of a Dissonance-Based Eating Disorders Intervention on Implicit Attitudes to Thinness in Women of Diverse Sexual Orientations

Dissonance-based body image programs have shown long-term effectiveness in preventing eating disorders and reducing risk factors for eating disorders in women. Here we report on the potential for one such intervention to impact on implicit attitudes toward thinness as well as an explicit measure of eating attitudes, across a sexually diverse group of young women. The Succeed Body Image Programme was adapted to remove heteronormative assumptions and was delivered to a final sample of 56 undergraduate women who reported their sexual orientation as either “predominantly heterosexual” (our term; 1 or 2 on a 7-point Kinsey scale, n = 38) or non-heterosexual (3–7 on the Kinsey scale, n = 18). Before and after the intervention, they completed the Eating Attitudes Test-26, and an associative reaction time task based on the Implicit Association Test, in which bodies of low and higher weight were paired with socially desirable or undesirable traits. A total of 37 predominantly heterosexual women completed a control intervention in which they read NHS leaflets on eating disorders and healthy weight. Results showed that the intervention made predominantly heterosexual participants less prone, versus control, to associating thinness with positive traits on the IAT and all women completing the intervention reported a lower level of disordered eating attitudes at post- than pre-test. Non-heterosexual women, however, showed a non-significant increase in thin-bias on the IAT, perhaps due to their low baseline. These results imply that intensive dissonance-based programs can change attitudes at the automatic, implicit level as well as merely giving women tools to overcome those implicit attitudes.

Risk of disordered eating at the intersection of gender and racial/ethnic identity among U.S. high school students

BACKGROUND

Gender and racial/ethnic disparities in disordered eating among youth exist, although whether having multiple marginalized identities disproportionately increases risk is unclear. Therefore, we aimed to quantify the risk of disordered eating associated with intersecting gender and racial/ethnic identities of U.S. adolescents.

METHODS

We analyzed data from 11,514 U.S. high school students identifying as White, Black/African American, or Hispanic/Latino who participated in the 2013 National Youth Risk Behavior Surveillance System. Age-adjusted relative risks (RR) of purging, fasting, diet pill use, and any disordered eating were estimated using log-binomial models. Relative excess risk due to interaction (RERI) was estimated to evaluate the degree to which the combined effect of marginalized gender and racial/ethnic identity was larger than the sum of their individual effects.

RESULTS

Disordered eating was prevalent (girls: 20.4% Black/African American, 29.2% Hispanic/Latina, 21.4% White; boys: 13.4% Black/African American, 12.4% Hispanic/Latino; 8.1% Whites). Girls of all racial/ethnic identities and racial/ethnic minority boys had elevated risks of purging, fasting, and any disordered eating compared to White boys (RR range = 1.57-7.43); Hispanic/Latina and White girls also had elevated risk of diet pill use (RR range = 1.98-3.20). Among Hispanic/Latina girls, positive interaction between gender and race/ethnicity produced excess risk of any disordered eating and purging (RERI: any = 0.42 (95% confidence interval (CI) = -0.02, 0.87); purging = 1.74 (95% CI = 0.06, 3.42).

CONCLUSIONS

Findings illustrate the advantages of adopting an intersectional approach to disordered eating research. Future research should investigate the mechanisms of these disparities.

A screening tool for detecting eating disorder risk and diagnostic symptoms among college-age women

Objective: As eating disorders (EDs) often emerge during college, managing EDs would ideally integrate prevention and treatment. To achieve this goal, an efficient tool is needed that detects clinical symptoms and level of risk. This study evaluated the performance of a screen designed to identify individuals at risk for or with an ED. Participants: Five hundred forty-nine college-age women. Methods: Participants completed a screen and diagnostic interview. Results: Using parsimonious thresholds for ED diagnoses, screen sensitivity ranged from 0.90 (anorexia nervosa) to 0.55 (purging disorder). Specificity ranged from 0.99 (anorexia nervosa) to 0.78 (subthreshold binge eating disorder) compared to diagnostic interview. Moderate to high area under the curve values were observed. The screen had high sensitivity for detecting high risk. Conclusions: The screen identifies students at risk and has acceptable sensitivity and specificity for identifying most ED diagnoses. This tool is critical for establishing stepped care models for ED intervention.

Prevention of eating disorders: 2018 in review

This article reviews the 10 prevention-related publications in Eating Disorders: The Journal of Treatment & Prevention during 2018. Two models frame this analysis. This first is the Mental Health Intervention Spectrum from health promotion → types of prevention → case identification and referral → treatment (recovery). The second parses the phases of prevention into rationale, theory, and methodology → clarification of risk factors, including very high risk, shading into warning signs → implications for specific preventive interventions → design innovation and feasibility (pilot) research → efficacy and effectiveness research → program dissemination. Collectively, the articles illustrate how complex and demanding the field of prevention is, with respect to, for example, phases of program development, the multidimensional ecology of interventions, and methodological requirements for demonstrating that a program deserves to be designated "evidence-based." A subset of the articles also illustrates how far the increasingly broad and dynamic field of prevention has advanced. Examples include models of eating disorder development in high-risk populations such as people with type 1 diabetes; prevention programming for young children; and after-school preventive interventions that combine dissonance-based lessons with empowering participation in community advocacy and activism.

Shared Concerns and Opportunity for Joint Action in Creating a Food Environment That Supports Health

The food industry is a for-profit industry with high relevance to universal eating disorders prevention. To date, policy which targets the food industry and food environment has been underutilized in efforts to decrease the incidence of eating disorders and associated risk factors. In contrast, food policy has been extensively leveraged with the aim of reducing the incidence of obesity. While philosophical misalignments with these later efforts may have constituted an obstacle to identifying the food environment as a key target for eating disorders prevention, food policy is an area where shared interests can be found. Specifically, a shared goal of obesity and eating disorders prevention efforts is creating a food environment that supports health, while minimizing the influence of the food industry that profits from the sale of highly palatable, processed foods and “diet” foods and from increasing portions of foods served and eaten.

Disordered Society: Women in Eating Disorder Recovery Advise Policymakers on Change

This qualitative study draws on a photo-elicitation method ("PhotoVoice") and semi-structured interviews to examine the key areas stakeholders (30 young women between the ages of 18 and 35 in eating disorder recovery) identify as meaningful venues of policy-based change. Photography and the accompanying narratives capturing personally-meaningful social, cultural, and systemic influences on recovery were shared with the research team. Photographs and interviews were examined for policy implications using thematic analysis, and six areas of improvement emerged: media, healthcare practice and access, health insurance reform, education, objectification of the female body, and mental health stigma. Implications for reform are discussed.

Feasibility and acceptability of a prevention program for eating disorders (Me, You and Us) adapted for young adolescents in Korea

PURPOSE

The aim of this study was to assess the adaptability and acceptability of a prevention program.

METHODS

A total of 169 Korean students (83 boys and 86 girls) with a mean age of 12.3 years from a 6th grade class at an elementary school participated in the study. Mental health social workers delivered Me, You and Us, a school-based body image intervention program originally developed in the UK, through a set of six sessions. The participants were assessed in terms of their body satisfaction and self-esteem before the program, after the program, and at 1-month follow-up. They were also surveyed about their satisfaction and acceptability levels after the program.

RESULTS

At baseline, girls had lower body satisfaction and self-esteem than boys, and their body satisfaction and self-esteem improved after the program. The improved body satisfaction was maintained at the 1-month follow-up. The efficacy of the program on body satisfaction was positively correlated with the frequency of their baseline level of "fat talk." The program was more effective in girls with possible symptoms of an eating disorder at baseline. 93.7% of boys and 77.4% of girls responded that they enjoyed the program.

CONCLUSIONS

The program Me, You and Us was well-accepted by early adolescents in Korea and it can play a role in increasing body satisfaction and self-esteem by reducing "fat talk" in 6th grade students.

Online prevention of disordered eating in at-risk young-adult women: a two-country pragmatic randomized controlled trial

BACKGROUND

Disordered eating (DE) is a widespread, serious problem. Efficacious prevention programs that can be delivered at-scale are needed.

METHODS

A pragmatic randomized controlled trial of two online programs was conducted. Participants were young-adult women from Australia and New Zealand seeking to improve their body image. Media Smart-Targeted (MS-T) and Student Bodies (SB) were both 9-module interventions released weekly, whilst control participants received positive body image information. Primary [Eating Disorder Examination-Questionnaire (EDE-Q) Global], secondary (DE risk factors) and tertiary (DE) outcome measures were completed at baseline, post-program, 6- and 12-month follow-up.

RESULTS

Baseline was completed by 608 women (M age = 20.71 years); 33 were excluded leaving 575 randomized to: MS-T (N = 191); SB (N = 190) or control (N = 194). Only 66% of those randomized to MS-T or SB accessed the intervention and were included in analyses with controls; 78% of this sample completed measures subsequent to baseline. Primary intent-to-treat (ITT) analyses revealed no differences between groups, while measure completer analyses found MS-T had significantly lower EDE-Q Global than controls at 12-month follow-up. Secondary ITT analyses found MS-T participants reported significantly higher quality of life-mental relative to both SB and controls (6-month follow-up), while MS-T and controls had lower clinical impairment relative to SB (post-program). Amongst measure completers, MS-T scored significantly lower than controls and SB on 5 variables. Of those with baseline DE, MS-T participants were significantly less likely than controls to have DE at 12-month follow-up.

CONCLUSIONS

Given both programs were not therapist-moderated, MS-T has potential to achieve reductions in DE risk at low implementation costs.

Innovation in eating disorders research and practice: Expanding our community and perspectives at the 2018 International Conference on Eating Disorders: Editorial to accompany IJED Virtual Issue in honor of the 2018 International Conference on Eating Disorders

OBJECTIVE

This virtual issue of the International Journal of Eating Disorders (IJED) highlights the excellent and innovative research and practice discussed at the 2018 International Conference on Eating Disorders held in Chicago, Illinois, USA.

METHOD AND RESULTS

The virtual issue contains a series of articles recently published in IJED, which we have curated to reflect and expand on the insights delivered during the conference keynote and plenary presentations.

DISCUSSION

In line with the conference theme of Innovation in Research and Practice: Expanding our Community and Perspectives, we hope this collection of articles will spark new ideas for research, practice, and collaboration to accelerate knowledge on eating disorder risk factors and recovery, and the reach and impact of evidence-based treatment, prevention, and policy efforts.

Research for leveraging food policy in universal eating disorder prevention

Policy and legislation have emerged as important levers for universal prevention efforts in the context of eating disorders. However, to date, little attention has been paid to generating research that will inform opportunities to regulate the food environment, specifically the way that food is produced and marketed. The present paper aims to lay out a framework for research that will examine (1) the ways in which food industry may influence risk for eating disorders and (2) the impact of legislative efforts on eating disorder cognitions and behaviors. For these two pathways, specific examples of research that would serve to inform policy efforts aiming to decrease the risk for eating disorders by targeting the food environment are proposed. Overall, the present paper aims to issue a call for the eating disorder field to become involved in food policy and regulation.

Maximizing the public health impact of eating disorder services: A simulation study

OBJECTIVE

Although effective interventions for eating disorders (ED) are available, the impact of health care services on a population level is far from satisfactory. A mathematical model of how health care for ED affects the population's disease burden can stimulate discussions and provide guidance about promising strategies to reduce ED-related suffering on the population level.

METHOD

The current health care situation for ED is modeled taking into account the reach and effectiveness of prevention, treatment, and aftercare, as well as incidence rates, relapse rates, and rates for spontaneous remissions. A first-order Markov model is applied and the effect of changes in single service parameters on the populations overall disease burden are simulated.

RESULTS

Improvements of treatment utilization and the reach of prevention programs would have the largest effects on the population's disease burden. Improving the efficacy of treatment, prevention, and aftercare show only limited effects.

DISCUSSION

In order to maximize the public health impact of health care for ED new models of treatment delivery as well as public health approaches to the prevention of ED are critical.

Universal prevention of eating disorders: A concept analysis

The definition of universal prevention is important for theoretical, research, and policy-related reasons. The present article provides an etymological and historical look at the concept of universal prevention, in and of itself and in terms of its position on the mental health intervention spectrum involving mental health promotion, selective prevention, indicated prevention, case identification, and treatment. Following a summary of the features commonly associated with universal prevention, these characteristics are fashioned into a family resemblance model for defining the construct. This model is applied to four of the articles constituting the journal Eating Behaviors' special issue on the universal prevention of eating disorders. It is argued that this family resemblance approach captures the diversity of current universal approaches to reducing risk factors and/or preventing eating disorders. This type of definition, coupled with Foxcroft's (2014) tripartite functional analysis of universal prevention, has the potential to improve evaluations of universal prevention, as well as large-scale collaborative projects that seek to integrate programs across the mental health intervention spectrum.

Addressing critical gaps in the treatment of eating disorders

Remarkable progress has been made in developing psychosocial interventions for eating disorders and other mental disorders. Two priorities in providing treatment consist of addressing the research-practice gap and the treatment gap. The research-practice gap pertains to the dissemination of evidence-based treatments from controlled settings to routine clinical care. Closing the gap between what is known about effective treatment and what is actually provided to patients who receive care is crucial in improving mental health care, particularly for conditions such as eating disorders. The treatment gap pertains to extending treatments in ways that will reach the large number of people in need of clinical care who currently receive nothing. Currently, in the United States (and worldwide), the vast majority of individuals in need of mental health services for eating disorders and other mental health problems do not receive treatment. This article discusses the approaches required to better ensure: (1) that more people who are receiving treatment obtain high-quality, evidence-based care, using such strategies as train-the-trainer, web-centered training, best-buy interventions, electronic support tools, higher-level support and policy; and (2) that a higher proportion of those who are currently underserved receive treatment, using such strategies as task shifting and disruptive innovations, including treatment delivery via telemedicine, the Internet, and mobile apps.

The economic case for digital interventions for eating disorders among United States college students

OBJECTIVE

Eating disorders (EDs) are serious health problems affecting college students. This article aimed to estimate the costs, in United States (US) dollars, of a stepped care model for online prevention and treatment among US college students to inform meaningful decisions regarding resource allocation and adoption of efficient care delivery models for EDs on college campuses.

METHODS

Using a payer perspective, we estimated the costs of (1) delivering an online guided self-help (GSH) intervention to individuals with EDs, including the costs of "stepping up" the proportion expected to "fail"; (2) delivering an online preventive intervention compared to a "wait and treat" approach to individuals at ED risk; and (3) applying the stepped care model across a population of 1,000 students, compared to standard care.

RESULTS

Combining results for online GSH and preventive interventions, we estimated a stepped care model would cost less and result in fewer individuals needing in-person psychotherapy (after receiving less-intensive intervention) compared to standard care, assuming everyone in need received intervention.

CONCLUSIONS

A stepped care model was estimated to achieve modest cost savings compared to standard care, but these estimates need to be tested with sensitivity analyses. Model assumptions highlight the complexities of cost calculations to inform resource allocation, and considerations for a disseminable delivery model are presented. Efforts are needed to systematically measure the costs and benefits of a stepped care model for EDs on college campuses, improve the precision and efficacy of ED interventions, and apply these calculations to non-US care systems with different cost structures.

Results of a strategic science study to inform policies targeting extreme thinness standards in the fashion industry

The appearance pressures experienced by fashion models have been criticized as harmful to their health, as well as increasing eating disorder risk among youth by promoting ideals of extreme thinness. Given recent legislation to protect models, we undertook a strategic science study to assess professional fashion models' perceptions of the potential impact and feasibility of seven policy proposals. A sample of 85 female fashion models, mean age = 22.7 years (SD 3.7) completed an online survey assessing unhealthy weight control behaviors (UWCB), perceived pressure from agencies to lose weight, as well as the perceived impact and feasibility of seven potential policy actions. Chi-squared analyses and multivariable logistic regressions compared UWCB among models who were asked to lose weight and those who were not. Friedman and Kendall's W tests were conducted to examine differences in impact and feasibility ratings across the seven policy proposals. Models reported high levels of pressure to lose weight, which was associated with higher odds of engaging in UWCB. The policy approaches rated as most impactful were those to increase worker protections, though they were rated as only moderately feasible. Requiring employers to provide food and a 30-min break for jobs longer than 6 h was rated as both impactful and feasible. Imposing restrictions on minimum BMI was rated as the least impactful. Approaches providing employment protections and healthier working conditions are most supported by professional models. These findings help to illuminate viable policy approaches from the perspective of key stakeholders.

Prevention of eating disorders: A systematic review and meta-analysis

OBJECTIVE

To systematically review and quantify the effectiveness of Eating Disorder (ED) prevention interventions.

METHODS

Electronic databases (including the Cochrane Controlled Trial Register, MEDLINE, PsychInfo, EMBASE, and Scopus) were searched for published randomized controlled trials of ED prevention interventions from 2009 to 2015. Trials prior to 2009 were retrieved from prior reviews.

RESULTS

One hundred and twelve articles were included. Fifty-eight percent of trials had high risk of bias. Findings indicated small to moderate effect sizes on reduction of ED risk factors or symptoms which occurred up to three-year post-intervention. For universal prevention, media literacy (ML) interventions significantly reduced shape and weight concerns for both females (-0.69, confidence interval (CI): -1.17 to -0.22) and males (-0.32, 95% CI -0.57 to -0.07). For selective prevention, cognitive dissonance (CD) interventions were superior to control interventions in reducing ED symptoms (-0.32, 95% CI -0.52 to -0.13). Cognitive behavioural therapy (CBT) interventions had the largest effect size (-0.40, 95% CI -0.55 to -0.26) on dieting outcome at 9-month follow-up while the healthy weight intervention reduced ED risk factors and body mass index. No indicated prevention interventions were found to be effective in reducing ED risk factors.

CONCLUSIONS

There are a number of promising preventive interventions for ED risk factors including CD, CBT and ML. Whether these actually lower ED incidence is, however, uncertain. Combined ED and obesity prevention interventions require further research.
