Supportive Interventions in Managing Eating Disorders: A Review of the Evolving Medical Professional Landscape.

Background: The landscape of healthcare for medical professionals is undergoing significant changes during a global rise in obesity and mental health issues, particularly in the context of eating disorders. The COVID-19 pandemic, coupled with sedentary lifestyles and job loss, has exacerbated food obsession and mental health challenges, highlighting the need for effective treatments. Objective: This review aims to explore the impact of supportive interventions in managing eating disorders within the evolving landscape of medical professionals' approaches, focusing on the adoption of new tools and approaches. Methods: A comprehensive analysis of current literature and data sources was conducted to examine the healthcare landscape's transformation and its implications for treating eating disorders. Various treatment modalities, including therapy, education, medication, and support groups, were evaluated in light of recent changes in medical practice. Results: The review identified a growing body of research highlighting the effectiveness of supportive interventions, such as cognitive behavior therapy, mindfulness, and participation in peer support groups in improving emotional eating patterns and facilitating long-term weight management. The findings underscore the growing prevalence of obesity and mental health issues, with a significant portion of individuals experiencing food obsession and overeating. Despite this, recognition and treatment of obesity-related psychological issues remain inadequate, partly due to a shortage of mental health professionals. Treatment options for eating disorders may include bariatric surgery, therapy, education, medication, and supportive interventions. Support groups such as Overeaters Anonymous (OA) have shown promise in helping individuals manage eating disorders and achieve healthier lifestyles. Conclusions: The shifting healthcare landscape necessitates a proactive approach from medical professionals to address the complex relationship between obesity, mental health, and eating disorders. Integrating peer support groups and holistic treatment approaches alongside traditional medical interventions can enhance outcomes and promote long-term weight management.

Rates and correlates of study enrolment and use of a chatbot aimed to promote mental health services use for eating disorders following online screening.

OBJECTIVE: We developed a chatbot aimed to facilitate mental health services use for eating disorders (EDs) and offered the opportunity to enrol in a research study and use the chatbot to all adult respondents to a publicly available online ED screen who screened positive for clinical/subclinical EDs and reported not currently being in treatment. We examined the rates and correlates of enrolment in the study and uptake of the chatbot. METHOD: Following screening, eligible respondents (≥18 years, screened positive for a clinical/subclinical ED, not in treatment for an ED) were shown the study opportunity. Chi-square tests and logistic regressions explored differences in demographics, ED symptoms, suicidality, weight, and probable ED diagnoses between those who enroled and engaged with the chatbot versus those who did not. RESULTS: 6747 respondents were shown the opportunity (80.0% of all adult screens). 3.0% enroled, of whom 90.2% subsequently used the chatbot. Enrolment and chatbot uptake were more common among respondents aged ≥25 years old versus those aged 18-24 and less common among respondents who reported engaging in regular dietary restriction. CONCLUSIONS: Overall enrolment was low, yet uptake was high among those that enroled and did not differ across most demographics and symptom presentations. Future directions include evaluating respondents' attitudes towards treatment-promoting tools and removing barriers to uptake.

Eating Disorder Specialist Views on Gender Competency and Education for Treating Gender Minority Patients.

Studies exploring patient experience with eating disorder specialists have reported poor gender competency among clinicians, as revealed through patient-clinician interactions. Through interviews with eating disorder specialists, the authors sought to (1) clarify how and why current practice and clinical training may not meet the needs of transgender and gender-diverse patients, (2) assess where and how clinicians received education on gender identity, and (3) how changes can be made to meet educational and patient needs. Specialists were recruited, and semi-structured interviews were conducted. Narratives were coded by two independent coders, using thematic analysis. Four key themes emerged from 19 completed interviews: Training and education received, importance of receiving training or education, self-education, and improvements recommended by clinicians. Only ~ 16% (n = 3) of clinicians reported sufficient training both in graduate school and through their place of employment. Most with sufficient education received it at their clinic/practice. Despite lacking formal training, all clinicians engaged in some form of self-education on gender. These findings support the need for standardized and comprehensive graduate curricula, in-service training, and continuing education requirements. Advocacy is required to encourage accrediting organizations to mandate training on gender among mental health clinicians.

Efficacy of Telephone-Based Cognitive Behavioral Therapy for Weight Loss, Disordered Eating, and Psychological Distress After Bariatric Surgery: A Randomized Clinical Trial.

Importance: Weight regain after bariatric surgery is associated with recurrence of obesity-related medical comorbidities and deterioration in quality of life. Developing efficacious psychosocial interventions that target risk factors, prevent weight regain, and improve mental health is imperative. Objective: To determine the efficacy of a telephone-based cognitive behavioral therapy (tele-CBT) intervention at 1 year after bariatric surgery in improving weight loss, disordered eating, and psychological distress. Design, Setting, and Participants: This multisite randomized clinical trial was conducted at 3 hospital-based bariatric surgery programs, with recruitment between February 2018 and December 2021. Eligibility for participation was assessed among 314 adults at 1 year after bariatric surgery who were fluent in English and had access to a telephone and the internet. Patients with active suicidal ideation or poorly controlled severe psychiatric illness were excluded. Primary and secondary outcome measures were assessed at baseline (1 year after surgery), after the intervention (approximately 15 months after surgery), and at 3-month follow-up (approximately 18 months after surgery). Data were analyzed from January to February 2023. Interventions: The tele-CBT intervention consisted of 6 weekly 1-hour sessions and a seventh booster session 1 month later. The control group received standard postoperative bariatric care. Main Outcomes and Measures: The primary outcome was postoperative percentage total weight loss. Secondary outcomes were disordered eating (Binge Eating Scale [BES] and Emotional Eating Scale [EES]) and psychological distress (Patient Health Questionnaire-9 item scale [PHQ-9] and Generalized Anxiety Disorder-7 item scale [GAD-7]). The hypotheses and data-analytic plan were developed prior to data collection. Results: Among 306 patients 1 year after bariatric surgery (255 females [83.3%]; mean [SD] age, 47.55 [9.98] years), there were 152 patients in the tele-CBT group and 154 patients in the control group. The group by time interaction for percentage total weight loss was not significant (F1,160.61 = 2.09; P = .15). However, there were significant interactions for mean BES (F2,527.32 = 18.73; P < .001), EES total (F2,530.67 = 10.83; P < .001), PHQ-9 (F2,529.93 = 17.74; P < .001), and GAD-7 (F2,535.16 = 15.29; P < .001) scores between the tele-CBT group and control group across all times. Conclusions and Relevance: This study found that tele-CBT delivered at 1 year after surgery resulted in no change in short-term weight outcomes but improved disordered eating and psychological distress. The impact of these psychosocial improvements on longer-term weight outcomes is currently being examined as part of this longitudinal multisite randomized clinical trial. Trial Registration: ClinicalTrials.gov Identifier: NCT03315247.

Efficacy of educational interventions in adolescent population with feeding and eating disorders: a systematic review.

BACKGROUND: Educational interventions are a key element in the care of young patients with feeding and eating disorders, forming part of the majority of therapeutic approaches. The aim of this review is to evaluate the impact of educational interventions in adolescents with feeding and eating disorders. METHODS: Following the PRISMA recommendations electronic databases were searched up to 29 June 2023. Studies related to educational interventions in young population diagnosed with feeding and eating disorders (anorexia nervosa, avoidant/restrictive food intake disorder, bulimia nervosa, pica and ruminative disorders and binge- eating disorder) in Spanish and English language, without temporal limitation, were located in the databases: PubMed, Scopus, CINAHL, Cochrane Library, PsycINFO, CUIDEN, DIALNET, and ENFISPO. A search in the databases of grey literature was performed in OpenGrey and Teseo. The review protocol was registered in PROSPERO (CRD42020167736). RESULTS: A total of 191 articles were selected from the 9744 citations screened. Ten publications were included. The results indicated variability between educational programs, including individual and group interventions, learning techniques and various research methodologies. Variables such as learning, attitudinal and perceptual changes, anthropometric parameters, symptom improvement, normalization of eating patterns, evaluation of the program and cognitive flexibility were identified. The risk of bias was high due to the low methodological quality of a large number of studies analyzed. CONCLUSION: The results indicate that educational interventions can influence the improvement of knowledge level and have a positive effect on health outcomes. Although education is a common practice in the treatment of these pathologies, high-quality studies were not identified. Thus, this review concludes that additional evidence is needed to evaluate the effectiveness of educational programs, with further research studies, especially randomized controlled trials, to confirm these results. LEVEL OF EVIDENCE: Level I: Systematic review.

How to address physical activity and exercise during treatment from eating disorders: a scoping review.

PURPOSE OF REVIEW: This scoping review aimed to provide a recent update on how to address dysfunctional physical activity and exercise (DEx), and on effects and experiences from including supervised and adapted physical activity or exercise (PAE), during treatment of eating disorders. RECENT FINDINGS: A systematic search for peer-reviewed publications in the period 2021-2023 generated 10 original studies and 6 reviews, including one meta-analysis (reporting according to PRISMA and SWiM). Findings showed that DEx was effectively managed by use of psychoeducation and/or PAE. Inclusion of PAE as part of treatment showed low-to-moderate impact on health and positive or neutral effects on eating disorder psychopathology. There were no reports of adverse events. For individuals with anorexia nervosa, PAE improved physical fitness with no influence on body weight or body composition unless progressive resistance training was conducted. For individuals with bulimia nervosa, DEx was reduced simultaneously with increased functional exercise and successful implementation of physical activity recommendations during treatment. Experiences by individuals with eating disorders and clinicians, including accredited exercise physiologists, pointed to positive benefits by including PAE in treatment. SUMMARY: Lack of consensus about DEx and of recommendations for PAE in official treatment guidelines hinder adequate approaches to these issues in eating disorder treatment.

The relation of food insecurity to eating disorder characteristics and treatment-seeking among adult respondents to the National Eating Disorders Association online screen.

BACKGROUND: Food insecurity (FI), characterized by limited or uncertain access to adequate food, has been associated with eating disorders (EDs). This study explored whether FI was associated with ED behaviors, ED diagnosis, current treatment status, and treatment-seeking intentions among adults who completed an online ED screen. METHODS: Respondents to the National Eating Disorders Association online screening tool self-reported demographics, FI, height and weight, past 3-month ED behaviors, and current treatment status. Respondents were also asked an optional question about treatment-seeking intentions. Hierarchical regressions evaluated relations between FI and ED behaviors, treatment status, and treatment-seeking intentions. Logistic regressions explored differences in probable ED diagnosis by FI status. RESULTS: Of 8714 respondents, 25 % screened at risk for FI. FI was associated with greater binge eating (R2Change = 0.006), laxative use (R2Change = 0.001), and presence of dietary restriction (R2Change = 0.001, OR: 1.32) (ps < .05). Having FI was associated with greater odds of screening positive for a probable ED or as high risk for an ED (ps < .05). FI was not associated with current treatment status or treatment-seeking intentions (ps > .05). CONCLUSIONS: Findings add to existing literature supporting a relation between FI and EDs. Implications include a need to disseminate EDs screening and treatment resources to populations affected by FI and to tailor treatments to account for barriers caused by FI.

Current approaches in the recognition and management of eating disorders.

Eating disorders are now well acknowledged mental health problems that are common and present in people from diverse sociodemographic backgrounds. The past decade has seen a rapid expansion in research into eating disorder interventions. In response to the increasing burden of eating disorders, the Australian Government Department of Health and Aged Care has implemented significant policy changes to improve patient access to Medicare and inpatient treatment facilities. There are several international clinical practice guidelines and a robust evidence base particularly for first line care with specific psychological therapies, including guidelines for the management of eating disorders in individuals with a high weight. Medications play an important adjunct role in care, and novel neuromodulating treatments, such as psychostimulants, are under study. There is emerging evidence for increased person-centred care, with more choice in the form of alternatives to hospital inpatient programs and more respectful consideration of care for all who experience an eating disorder, including people with high weight.

Change in adaptive and maladaptive exercise and objective physical activity throughout CBT for individuals with eating disorders.

Maladaptive exercise (i.e., exercise that compensates for binge eating or is used to avoid negative consequences of not exercising-like weight gain) is a common eating disorder (ED) behavior, yet, some individuals with EDs only engage in adaptive exercise. CBT for EDs targets reducing maladaptive exercise but does not address adaptive exercise. Thus, research is limited on how adaptive and maladaptive exercise are impacted during CBT for EDs. The current study examined how assessor-rated adaptive and maladaptive exercise and objectively measured physical activity changed over a 12-week CBT treatment among adults with transdiagnostic binge eating and restrictive eating that did and did not engage in maladaptive exercise at the start of treatment (n = 13 non-maladaptive exercise group, n = 17 maladaptive exercise group). The overall amount of adaptive and maladaptive exercise was measured via the Eating Disorder Examination Interview and objectively measured physical activity (e.g., step count, minutes of moderate-to-vigorous physical activity [MVPA]) was measured via a wrist-worn fitness tracker. Throughout treatment, the overall amount of adaptive exercise did not significantly change for both groups, but the overall amount of maladaptive exercise significantly decreased in the maladaptive exercise group. Step count did not significantly change for both groups, but minutes of MVPA significantly increased over treatment for the non-maladaptive exercise group. Increases in step count and minutes of MVPA were not associated with ED symptom changes in either group. These results enhance an understanding of exercise changes during transdiagnostic CBT-based ED treatment for individuals with varying baseline exercise profiles.Level of evidence: Level 1, randomized controlled trial.

Considerations of eating disorder risk during obesity treatment in Australia: Current practice, attitudes and barriers.

INTRODUCTION: People with obesity are vulnerable to eating disorders. It has been suggested that screening for eating disorder risk be part of obesity care. However, it is unclear what current practice entails. OBJECTIVE: To explore considerations of eating disorder risk during treatment of obesity, including assessment and intervention strategies used in clinical practice. MATERIALS AND METHODS: An online (REDCap) cross-sectional survey was distributed to health professionals working with individuals with obesity in Australia through professional societies and social media. The survey had three sections: 1. Characteristics of Clinician/Practice, 2. Current Practice, 3. Attitudes. Data were summarised using descriptive statistics and free-text comments were independently coded in duplicate to identify themes. RESULTS: 59 health professionals completed the survey. Most were dietitians (n = 29), identified as women (n = 45) and worked within a public hospital (n = 30) and/or private practice (n = 29). Overall, 50 respondents reported assessing for eating disorder risk. Most reported that having a history of, or risk factors of eating disorders should not preclude obesity care but emphasised the importance of treatment modification including using a patient-centred approach involving a multidisciplinary team and promoting healthy eating behaviours, with less emphasis on calorie restriction or bariatric surgery. Management approaches did not differ for those with eating disorder risk factors or a diagnosed eating disorder. Clinicians identified the need for additional training and clear referral pathways. CONCLUSION: Individualised care, balancing models of care for eating disorders and obesity and further access to training and services will be important in improving care of patients with obesity.

Fifteen-minute consultation: Recognition and management of eating disorders presenting to the emergency department.

Eating disorder presentations in children and young people during the COVID-19 pandemic have increased, and this has become a common presentation to paediatric emergency departments (EDs). We cover a structured approach on identifying and managing these presentations within the ED including history taking, what to look for on examination, what investigations are needed and how to decide who requires admission to hospital.

Holding Hope: Co-producing eating disorders education that integrates the lived experience voice to inform best practice.

WHAT IS KNOWN ON THE SUBJECT?: Eating Disorder (ED) education is predominating taught through a DSM-V diagnostic criteria and clinically focused lens devoid of lived experience expertise. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Current clinically focused ED education may be shaping health professional misunderstandings of EDs, influencing the therapeutic relationships between health professional and consumer which is key to the recovery process. Integrating the lived experience voice through co-produced, humanities-based ED education deepens understandings and honours the complexities of EDs by bringing a much-needed, alternate perspective to health professional learning, practice and research. WHAT ARE THE IMPLICATIONS FOR MENTAL HEALTH NURSING?: Reframing mental health education towards a more strengths-based, trauma-informed and recovery focused lens has the potential to upskill the health workforce in how to hold hope, space and learn to walk the fight with people living and recovering with an ED.

Universal healthcare reform for community treatment of eating disorders in Australia: report of the first 2 years of operation.

OBJECTIVE: The Australian Government's landmark 2019 implementation of dedicated Medicare items for people with eating disorders was the first of its kind for a mental illness. We investigate the first 24 months of uptake of these items across regions, settings and healthcare disciplines, including intermediate changes to the program prompted by the COVID-19 pandemic. METHODS: This was a descriptive study using item data extracted from the Australian Medicare Benefits Schedule database for November 2019 to October 2021. Data were cross-tabulated by discipline, setting, consultation type and region. RESULTS: During the first 24 months of implementation of the scheme, 29 881 Eating Disorder Treatment and Management Plans (or care plans) were initiated, mostly by general practitioners with mental health training. More than 265 000 psychotherapy and dietetic sessions were provided, 29.1% of which took place using telehealth during the pandemic. Although the program offers up to 40 rebated psychological sessions, fewer than 6.5% of individuals completed their 20-session review under the scheme. CONCLUSIONS: Uptake of the Medicare item for eating disorders was swift, and the item was used broadly throughout the pandemic. Although feedback from those with lived experience and experts has been overwhelmingly positive, data show that strategic adjustment may be needed and further evaluation conducted to ensure that the reform achieves the best outcomes for patients and families, and its policy intent.

Development and usability testing of a chatbot to promote mental health services use among individuals with eating disorders following screening.

OBJECTIVE: A significant gap exists between those who need and those who receive care for eating disorders (EDs). Novel solutions are needed to encourage service use and address treatment barriers. This study developed and evaluated the usability of a chatbot designed for pairing with online ED screening. The tool aimed to promote mental health service utilization by improving motivation for treatment and self-efficacy among individuals with EDs. METHODS: A chatbot prototype, Alex, was designed using decision trees and theoretically-informed components: psychoeducation, motivational interviewing, personalized recommendations, and repeated administration. Usability testing was conducted over four iterative cycles, with user feedback informing refinements to the next iteration. Post-testing, participants (N= 21) completed the System Usability Scale (SUS), the Usefulness, Satisfaction, and Ease of Use Questionnaire (USE), and a semi-structured interview. RESULTS: Interview feedback detailed chatbot aspects participants enjoyed and aspects necessitating improvement. Feedback converged on four themes: user experience, chatbot qualities, chatbot content, and ease of use. Following refinements, users described Alex as humanlike, supportive, and encouraging. Content was perceived as novel and personally relevant. USE scores across domains were generally above average (~5 out of 7), and SUS scores indicated "good" to "excellent" usability across cycles, with the final iteration receiving the highest average score. DISCUSSION: Overall, participants generally reflected positively on interactions with Alex, including the initial version. Refinements between cycles further improved user experiences. This study provides preliminary evidence of the feasibility and acceptance of a chatbot designed to promote motivation for and use of services among individuals with EDs. PUBLIC SIGNIFICANCE: Low rates of service utilization and treatment have been observed among individuals following online eating disorder screening. Tools are needed, including scalable, digital options, that can be easily paired with screening, to improve motivation for addressing eating disorders and promote service utilization.

Evaluation of a one-hour asynchronous video training for eating disorder screening and referral in U.S. Pediatric Primary Care: A pilot study.

OBJECTIVE: Develop and pilot-test the efficacy of an online training in improving comfort, knowledge, and behaviors related to eating disorders (EDs) screening among U.S.-based pediatric primary care providers (PCPs). METHODS: PCPs (N = 84) completed a baseline survey assessing comfort, knowledge, and behaviors regarding ED screening and referral, then watched a 1-h training video followed by a post-video survey. Half of the participants were randomly assigned to complete spaced-education questions in the following 2 months. All participants completed a 2-month follow-up survey. We used McNemar's and McNemar-Bowker tests to assess differences from baseline to post-video and post-video to follow-up, and logistic models to assess differences by spaced-education condition. RESULTS: From baseline to post-video, there were significant improvements in PCPs' knowledge about and comfort in screening and making referrals for EDs (p < .05). There were no differences between spaced-education conditions in knowledge and behaviors from baseline or post-video to follow-up, but spaced-education participants reported significantly greater comfort in screening for BN (p < .01) and BED (p < .01) compared to non-spaced-education participants. DISCUSSION: Findings suggest that a 1-h asynchronous training can improve PCP comfort, knowledge, and behavior in screening for EDs; spaced-education may provide slight additional benefits in PCP comfort. PUBLIC SIGNIFICANCE: The delivery of an 1-h asynchronous online video training helped to improve PCPs' comfort, knowledge, and behavior in screening and referral for EDs among pediatric populations. This has implications for future evaluations of brief trainings among this provider population, which could ultimately help to improve early identification of EDs and referrals to appropriate treatment.

Addressing eating disorders in primary care: Understanding screening recommendations and opportunities to improve care.

OBJECTIVE: For the first time in its history, the United States Preventive Services Task Force (USPSTF) published a recommendation on screening for eating disorders among adolescents and adults in primary care. The current manuscript provides an overview of the USPSTF recommendation, screening principles, and suggestions for clinical and research efforts. METHOD: The USPSTF based their recommendations on a rigorous systematic review of the evidence on routine screening for eating disorders. Eligible studies included studies of screening test accuracy and controlled trials of screening or interventions for eating disorders in screen-detected or previously untreated eating disorders. The current manuscript briefly summarizes the results of this evidence review which are published in full elsewhere and focuses on providing interpretation of the recommendations by clarifying the scope and methodology of the USPSTF. RESULTS: Fifty-seven studies were included in the evidence review. Seventeen studies evaluated screening test accuracy and 40 trials evaluated interventions among populations with previously untreated eating disorders. No studies directly assessed the benefits and harms of screening. The evidence review highlights important gaps in our knowledge regarding eating disorders in primary care. The authors provide recommendations for future studies in light of these evidence gaps and propose specific clinical strategies to improve care for those with eating disorders who present to primary care. DISCUSSION: Primary care can play an important role in the early detection of eating disorders, but data are needed to more fully understand the potential benefits and harms of routine screening in this setting. PUBLIC SIGNIFICANCE: There are gaps in the evidence regarding the benefits and harms of eating disorder screening in primary care. Future studies are needed to improve certainty about the net benefit of screening. Of particular importance are studies that compare routine screening to usual care (no screening). Current providers may benefit from tailored eating disorders education and training, practical tools, and integration of mental health services in primary care.

[Reducing stigma-discrimination. Help seeking-empowerment. Emotional education-mental health literacy]. / Disminuir la estigmatización-discriminación. Búsqueda de la ayuda-empoderamiento. Educación emocional-alfabetización en salud mental.

Introduction: The existing literature is reviewed to determine the current state of knowledge about eating disorders (ED), prevention programs in relation to stigma-discrimination, help search, empowerment, emotional education, mental health literacy, and recommending future directions. Preventive interventions, necessary during adolescence and young adulthood, must be designed with the focus on reducing discrimination based on weight and the stigmatization of ED. With some gender specificities, with attention to stress and social isolation, social consensus, EDs in men; with work to reduce compliance with some norms of the male gender, as one of the targets in the development of prevention programs. And reduce teasing by peers and family, experiences of stigmatization with the family and at work, which predict greater internalization of prejudice due to weight (IPP). And carry out mental health literacy activities such as the Media Smart program, promote help seeking, empowerment as in the REBel program and improve emotional education, the management of negative emotions with activities for the improvement of emotions, in addition to the Body Project (cognitive dissonance).

Introducción: Se revisa la bibliografía existente para determinar el estado actual del conocimiento acerca de los programas de prevención de TCA en relación con la estigmatización-discriminación, la búsqueda de ayuda, el empoderamiento, la educación emocional, la alfabetización en salud mental y recomendar futuras direcciones. Hay que diseñar intervenciones preventivas, necesarias durante la adolescencia y la edad adulta joven, con el foco en reducir la discriminación basada en el peso y la estigmatización de los TCA. Con algunas especificidades por género, con atención al estrés y el aislamiento social, el consenso social, los TCA en varones; con trabajo en disminuir la conformidad con algunas normas del género masculino, como una de las dianas en el desarrollo de los programas de prevención. Y disminuir las burlas por compañeros y familia, las experiencias de estigmatización con la familia y en el trabajo, que predicen mayor internalización de prejuicio por el peso (IPP). Y realizar actividades de alfabetización de salud mental como el programa Media Smart, fomentar la búsqueda de ayuda y el empoderamiento como en el programa REBel, y mejorar la educación emocional y el manejo de las emociones negativas con actividades para la mejora de las emociones, adicionales al Body Project (disonancia cognitiva).

[Physical exercise and sports in eating disorders]. / Actividad física y deporte en los trastornos de la conducta alimentaria.

Introduction: Physical activity (PA) is recognized as a key aspect in the prevention and treatment of psychological problems. PA recommendations to maintain and improve mental health were recently updated. Despite the fact that PA can be pivotal in interventions to prevent and treat eating disorders (ED), the role and dose of PA for this purpose are unknown. The papers analyzed in this review highlight the importance of PA in intervention programs to prevent and treat ED. Emerging evidence suggests that the PA we enjoy practicing, considered important and chosen, is associated with a positive effect on mental health, while the PA performed out of a feeling of guilt, pressure or a feeling of being forced to do it is associated with a negative effect. This review highlights that the evidence available is limited to suggest a harmful impact of PA in primary prevention interventions for eating disorders and suggests practical recommendations for future interventions as well as recommendations for future research.

Introducción: La actividad física (AF) está reconocida como un aspecto clave en la prevención y tratamiento de problemas psicológicos. Recientemente se han actualizado las recomendaciones de su práctica con el fin de mantener y mejorar la salud mental. La AF puede resultar de gran importancia en las intervenciones para prevenir y tratar los trastornos de la conducta alimentaria (TCA). Sin embargo, se desconocen el rol y la dosis para este fin. Los trabajos presentados en la revisión destacan la importancia de la AF en los programas de intervención para prevenir y tratar los TCA. La evidencia emergente sugiere que la AF que disfrutamos, considerada importante y elegida, se asocia con un efecto positivo para la salud mental, mientras que la AF realizada por un sentimiento de culpa, presión o sentimiento de estar forzado a realizarla se asocia a un efecto negativo. La revisión realizada destaca que no hay suficiente evidencia para sugerir que hay un impacto nocivo de la AF en las intervenciones de prevención primaria de los TCA. Se proponen recomendaciones prácticas dentro de futuras intervenciones, así como, recomendaciones para futuras investigaciones.
