Exercise in Eating Disorders Treatment: Systematic Review and Proposal of Guidelines

Movement Awareness Therapies in Eating Disorders: A Systematic Review and Meta-Analysis

Given the rising prevalence and complexity of eating disorders, a comprehensive multidisciplinary holistic approach is necessary. This work aimed to assess the effectiveness of body and movement awareness therapies in patients with eating disorders. Search strategy was undertaken using several scientific health databases. Articles were eligible if they were randomized controlled trials analyzing the effects of movement and body awareness therapies in eating disorders. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement for systematic reviews was followed and the risk of bias was assessed using the "Cochrane Collaboration Tool to assess the risk of bias." 11 articles met the inclusion criteria, including 437 patients. No high-quality randomized controlled trials were found. Forest plot analysis of the Eating Disorder Examination scale showed a difference favors to body awareness therapies but not significantly neither homogeneous. The interventions analyzed included yoga, body awareness therapy, dance, and psychomotor therapy. Body awareness therapies provide some additional benefits for eating disorder symptoms, such as emotion regulation, self-criticism, self-confidence, self-compassion, anxiety, body attitude, eating disorder symptoms, and quality of life.

Embracing a different outlook: Strengths and goals of individuals currently in treatment for anorexia nervosa

PURPOSE

Developing personal goals beyond weight and shape, and promoting the agency to pursue those goals, could aid in treatment and recovery from anorexia nervosa (AN). This research explores the strengths, interests and goals of individuals currently receiving treatment for AN and evaluates how treatment services are supporting them to work towards personal goals across all areas of everyday life.

METHOD

A total of 58 community-dwelling adults currently receiving treatment for anorexia nervosa at any stage of recovery completed the Client Assessment of Strengths, Interests and Goals Self-Report (CASIG-SR). Participants reported their goals for accommodation, work and study, interpersonal relationships, recreational activities, spirituality, religion or life purpose, physical health and mental health, and the personal strengths and supports needed to achieve those goals. Concordance scores were calculated between importance of personal goals and level of support from current services regarding these goals.

RESULTS

Themes identified across goals, strengths and supports were Connection, Independence & Confidence, Meaning & Self: The Real Me, and Stability & Balance. Work and study goals and strengths were identified strongly. The key support needed was stability from the current treatment team to provide a stable base for change. Concordance scores indicate support provided for personal goals was less than the importance of the goal to the individual.

CONCLUSION

Results suggest goals for everyday living are critical to recovery in anorexia nervosa. Specific clinical considerations to increase motivation and hope are increased access to peer support, a focus on increasing positive affect, supporting safe exercise and promoting outdoor experiences and connection with nature.

Disordered Eating in Pediatric Obesity

Children and youth with overweight and obesity are at an increased risk for the development of an eating disorder. Previous research has shown that disordered eating behaviors are prevalent in this population. Screening for disordered eating behaviors in children and youth with overweight and obesity is necessary to determine the course of the treatment. In children and youth with obesity and comorbid disordered eating behaviors, treatment should be multidisciplinary and include psychological, medical, nutrition, and physical activity care.

Relationship between nonexercise activity and mood in patients with eating disorders

INTRODUCTION

Many patients with eating disorders (EDs) engage in excessive and compulsive physical activity (pathological exercise, PE) to regulate negative mood or to "burn calories." PE can lead to negative health consequences. Non-exercise activity (NEA) bears the potential to serve as intervention target to counteract PE and problematic eating behaviors since it has been associated with positive mood effects. However, to date, there is no investigation on whether the positive link between NEA and mood seen in the healthy translates to patients with ED.

MATERIAL AND METHODS

To study potential associations of NEA and mood in ED, we subjected 29 ED-patients and 35 healthy controls (HCs) to an ambulatory assessment study across 7 days. We measured NEA via accelerometers and repeatedly assessed mood on electronic smartphone diaries via a mixed sampling strategy based on events, activity and time. Within- and between-subject effects of NEA on mood, PE as moderator, and the temporal course of effects were analyzed via multilevel modeling.

RESULTS

NEA increased valence (β = 2.12, p < 0.001) and energetic arousal (β = 4.02, p < 0.001) but showed no significant effect on calmness. The effects of NEA on energetic arousal where significantly stronger for HCs (βHC = 6.26, p < 0.001) than for EDs (βED = 4.02, p < 0.001; βinteraction = 2.24, p = 0.0135). Effects of NEA were robust across most timeframes of NEA and significantly moderated by PE, that is, Lower PE levels exhibited stronger NEA effects on energetic arousal.

CONCLUSION

Patients with ED and HC show an affective benefit from NEA, partly depending on the level of PE. If replicated in experimental daily life studies, this evidence may pave the way towards expedient NEA interventions to cope with negative mood. Interventions could be especially promising if delivered as Just-in-time adaptive interventions (JITAIs) and should be tailored according to the PE level.

Exercise and mind-body exercise for feeding and eating disorders: a systematic review with meta-analysis and meta-regressions

PURPOSE

To develop a systematic review with meta-analysis to summarize the effectiveness of exercise, regular physical activity, and mind-body exercise on harmful exercise habits, psychological factors, and quality of life in people clinically diagnosed with feeding and eating disorders.

MATERIAL AND METHODS

Randomized clinical trials and pilot randomized clinical trials were considered.

RESULTS

Twelve studies were included. No studies evaluated athletes. No studies examined regular physical activity as the targeted intervention. Quality of life could not be meta-analyzed. Overall, meta-analyses showed that exercise or mind-body exercise was not more effective than controls in reducing depression symptoms, harmful exercise habits, eating behaviors, or emotional regulation skills. However, important methodological and clinical issues were detected in the included studies. This affected the certainty of evidence of the meta-analyzed outcomes which ranged from low to very low. No studies reported in sufficient detail their interventions to be replicated.

CONCLUSIONS

Overall, exercise and mind-body exercise may be ineffective in improving meta-analyzed outcomes. However, the certainty of evidence ranged from low to very low and the body of knowledge in this field needs to be increased to reach robust conclusions.

Longitudinal description and prediction of physical inactivity among patients with borderline personality disorder and personality-disordered comparison subjects

BACKGROUND

The physical and psychological benefits of physical activity are well-known, and physical activity has been proven to be a helpful adjunct to psychotherapeutic treatment for many symptomatic disorders, including mood and anxiety disorders. The current study explores physical inactivity levels in patients with borderline personality disorder (BPD). The first aim of this study is to describe the 12-year course of physical inactivity in patients with BPD. The second aim is to examine predictors of physical inactivity, including adversity experiences, comorbid symptomatic (formerly axis I) disorders, medical disorders, and demographic factors.

METHODS

Two hundred and forty-five patients with BPD were interviewed seven times over 12-years of prospective follow-up as part of the McLean Study of Adult Development (MSAD). Patients were categorized as ever-recovered (i.e., patient had experienced a symptomatic and psychosocial recovery from BPD) or never-recovered. At each follow-up, patients reported physical activity levels (minutes of exercise per week) via a semi-structured interview- the Medical History and Services Utilization Interview (MHSUI). Data was collected from June 1992 to December 2018.

RESULTS

Never-recovered patients with BPD were significantly more inactive than their ever-recovered counterparts (p < 0.001). These rates of inactivity remained stable over time for both groups. Two significant multivariate predictors of inactivity were found: obesity (p = 0.003) and PTSD (p < 0.001).

CONCLUSIONS

Non-recovered BPD patients are more likely to be inactive than patients who have recovered. Both clinical and medical factors appear to contribute to inactivity levels in patients with BPD.

"Some distance between us": a UK mixed methods study exploring experiences of remote care for eating disorders during COVID-19

Introduction

COVID-19 necessitated a rapid move from face-to-face services to remote care for eating disorders/eating distress (EDs). This study explores the advantages and challenges of remote care, identifying future implications for service provision. Remote care has been considered in the broadest of terms, including therapeutic care (e.g., Cognitive Behavioural Therapy, peer support, forums, one-to-one and group care options).

Methods

Using a mixed methods approach, data were collected from 211 people with lived experience of EDs (PWLE), with and without formal diagnosis. 27 participants took part in semi-structured interviews/workshops and a further 184 participants took part via an online survey. Participants reported on their ED status, the impact of the pandemic on symptoms, the benefits, and challenges of remote care (and type of support accessed), and any reasons for not accessing support. Participants were invited to make future care recommendations.

Results

ED symptoms were reported as worsening during the pandemic with contributing factors including isolation, lack of routine, negative emotions, and feeling like the external situation was outside of one's control. Remote care was positively attributed to increased flexibility and facilitation of social connection. Identified barriers to access included lack of awareness about support availability, digital access/literacy, and competing commitments. Further challenges included approaches being perceived as too clinical (e.g., ED information and support presented using clinical language and/or limited to support within medical care settings, without acknowledging the broader context of disordered eating), uncertainty around remote care quality, and concerns that remote platforms may facilitate masking of symptoms. Participants reported distress caused by online platforms where self-view is the default during video calls. They expressed a need for more holistic approaches to remote care, including: "real stories" of recovery, and hybrid (online and offline) options for greater flexibility and widening of access and choice. Participants also expressed a need for appropriate digital literacy training.

Discussion

Future recommendations emphasise user-centred holistic and hybrid approaches to ED remote support, with training to address digital literacy barriers and facilitate user control of platform functionalities (e.g., self-view). This study underscores the need for continued remote care with a focus on inclusivity and user empowerment.

New understandings meet old treatments: putting a contemporary face on established protocols

In the twenty years since the publication of the most widely used treatment manuals describing evidence-based therapies for eating disorders, there have been some substantial advances in the field. New methods of delivering treatments have been trialled and our perception of mental health has advanced; significant cultural changes have led to shifts in our societal landscape; and new technologies have allowed for more in-depth research to be conducted. As a result, our understanding of eating disorders and their treatment has broadened considerably. However, these new insights have not necessarily been translated into improved clinical practice. This paper highlights the changes we consider to have had the greatest impact on our work as experienced clinical psychologists in the field and suggests a list of new learnings that might be incorporated into clinical practice and research design.

Moving to Improve Mental Health - The Role of Exercise in Cognitive Function: A Narrative Review

This review study investigates how exercise can enhance cognitive ability and mental wellness. Physical activity has been linked to a number of beneficial effects on cognitive function, including increased memory and executive function in adults, improved academic performance in children and adolescents, and potential advantages for people with cognitive impairments or neurodegenerative diseases. Increased cerebral blood flow, the synthesis of neurotrophic factors, and a decrease in oxidative stress and inflammation are the processes driving these effects. Studies have shown that exercise has mood-regulating benefits, with symptoms of anxiety and sadness lessening as a result. These mood-enhancing effects are a result of the endocannabinoid system being activated, endorphins being released, and changes in self-esteem and body image. Exercise therapies have also demonstrated the potential to encourage cognitive health as people age and lower the likelihood of cognitive decline. Exercise has been investigated as an adjuvant treatment for mental health illnesses, such as depression, anxiety disorders, schizophrenia, bipolar disorder, and eating disorders, in addition to its preventive effects. Exercise can improve the effectiveness of treatment and general wellbeing when it is incorporated into comprehensive treatment strategies. To identify the ideal exercise parameters for certain outcomes and overcome barriers to exercise participation, more study is necessary. We can get closer to enhancing general wellbeing and quality of life by including exercise in measures for promoting mental health and cognitive health.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

DISCUSSION

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

PUBLIC SIGNIFICANCE

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

Adaptive and Maladaptive Exercise in Eating Disorders

While exercise is generally associated with positive health outcomes, in the context of eating disorders, exercise has high potential to become maladaptive. Maladaptive exercise is compelled or compulsive in nature for the purposes of weight and shape control or to obtain/avoid other eating disorder-relevant consequences. A transdiagnostic eating disorder feature with moderate-to-high prevalence across restrictive- and bulimic-spectrum eating disorders, maladaptive exercise is often associated with negative mental and physical health sequalae. Several proposed threat- and reward-related biobehavioral mechanisms may initiate or perpetuate maladaptive exercise. While exercise is generally contraindicated during periods of acute medical concern, adaptive forms of exercise are also present among those with eating disorders, and facilitation of adaptive exercise has potential to promote physical and mental health benefits during eating disorder recovery. Detailed assessment and targeted interventions are needed to address the clinical conundrum of how and when to integrate exercise into eating disorder treatment.

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.

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.

Medical and physiological complications of exercise for individuals with an eating disorder: A narrative review

Individuals with eating disorders (ED) experience prolonged malnutrition, binge episodes, and compensatory behaviours that affect every organ system. Psychological and physiological symptoms are worsened with comorbid dysfunctional exercise, seen in up to 80% of those with an ED. Although return to exercise is an important component of treatment and recovery, little is known about the contraindications and risks of exercise engagement specific to those with an ED. This paper provides a comprehensive narrative review of the medical and physiological complications of engaging in exercise during ED treatment and outlines when exercise may be contraindicated or used in modified or cautionary ways. We conducted a literature search on MEDLINE, PubMed, and PsychArticles to identify relevant articles, which yielded six categories of medical and physiological complications of ED that may be exacerbated by exercise: energy availability, cardiovascular health, electrolyte abnormalities, biomedical function markers, sex hormones, and body composition. We summarize the evidence for these complications for readers and offer an initial set of recommendations for incorporating exercise during ED treatment based on our findings. This review may serve as a resource for members of ED treatment teams to help evaluate more readily and confidently whether exercise is safe for individual patients and when modifications and caution may be warranted.

Cardiopulmonary exercise testing for patients with anorexia nervosa: a case-control study

PURPOSE

Patients with anorexia nervosa (AN) require appropriate nutrient therapy and physical activity management. Eating disorder treatment guidelines do not include safe, evidence-based intensity criteria for exercise. This study used cardiopulmonary exercise testing (CPX) to evaluate the exercise tolerance of patients with AN.

METHODS

CPX was performed with 14 female patients with AN admitted to a specialized eating disorder unit between 2015 and 2019. Their anaerobic threshold (AT) was determined by assessing their exercise tolerance using CPX and compared with 14 healthy controls (HC). The metabolic equivalents (AT-METS) were compared when AT was reached. We examined factors related to AT (AN-AT) in the AN group, including age, body mass index (BMI), previous lowest weight, minimum BMI, past duration of BMI < 15, exercise history, and ΔHR (heart rate at the AT-resting heart rate).

RESULTS

The AT of the AN group (BMI: 15.7 [Mean] ± 1.8 standard deviation [SD]) was significantly lower than that of the HC group (BMI: 19.7 ± 1.8) (AN: 10.0 ± 1.8 vs. HC: 15.2 ± 3.0 ml/kg/min, P < 0.001). AT-METS was also significantly lower in the AN group than in the HC group (AN: 2.9 ± 0.52 vs. HC: 4.4 ± 0.91, P < 0.001). AN-AT was highly influenced by ΔHR.

CONCLUSIONS

This study showed that AT and AT-METS were lower in patients with AN than in HC. Patients with AN should be prescribed light-intensity aerobic exercise, and the current findings may help develop future physical management guidelines for patients with AN.

Compulsive exercise in eating disorders: Validation of the Italian scale and evaluation of its relationships with body image concerns and quality of life

BACKGROUND

Compulsive exercise (CE) has been proposed as one of the maladaptive elements that might concur to developing and maintaining an eating disorder (ED), even if no conclusive consensus is yet available. This study evaluates the psychometric properties of the Compulsive Exercise Test (CET), the questionnaire most frequently discussed in the literature. Our second aim is to evaluate the relationships between CE, quality of life, and different body concerns in a group of individuals.

METHODS

Two different studies are performed. In the first study, we evaluate the psychometric properties of the Italian CET with a sample of 272 individuals (157 with different diagnoses of ED). In the second study, a group of 75 ED patients is compared to 68 of their peers looking for specific differences and relationships between CE, quality of life, and body concerns.

RESULTS

The CET shows optimal psychometric proprieties, and a five-factors structure. CE is linked to more severe specific psychopathology in ED patients, including increased thoughts of restraint and concerns about weight and shape. Moreover, weight phobia and quality of life are predictors of CE in patients.

CONCLUSION

The specific role of CE is discussed according to its connections with a core psychopathological element like weight phobia. Specific profiles of CE emerged for each clinical subgroup, and they corroborate the presence of different cognitive/physical approach to exercise. The CE showed to be a dysfunctional element with a disruptive role in patients' quality of life. Future directions and possible applications of the CET are also discussed.

Relationships between personality traits and disordered eating among Chinese female exercisers: the role of symptoms of exercise dependence and obsessive-compulsiveness

BACKGROUND

Although numerous studies have examined associations between personality traits and eating disorders in females, few studies have been conducted on female exercisers. Given the high risk of disordered eating in female exercisers, this study investigated the associations between the Big Five personality traits and disordered eating in female exercisers, and further explored the potential mediators, namely exercise dependence symptoms, and obsessive-compulsive symptoms underlying this association.

METHODS

A total of 295 female exercisers aged between 18 to 67 years (M =  22.11, SD =  6.65) participated in this study.

RESULTS

Negative and statistically significant correlations between conscientiousness (r = - 0.17, p < 0.01), emotional stability (r = - 0.27, p < 0.001) and agreeableness (r = - 0.18, p < 0.01) and disordered eating were observed in our sample of female exercisers. The multiple mediation analyses revealed that exercise dependence symptoms and obsessive-compulsive symptoms mediate the relationship between conscientiousness (β = 0.016, CI = [0.003, 0.031]), emotional stability (β = -0.012, CI = [- 0.028, - 0.002]), and disordered eating in female exercisers, whereas obsessive-compulsive symptoms (β = - 0.041, CI = [- 0.088, - 0.001]) but not exercise dependence symptoms are a mediator of the relationship between agreeableness and disordered eating.

CONCLUSIONS

Our findings can be used to improve the screening procedures for eating disorders in female exercisers as they contribute to a better understanding of the psychological mechanisms that underlie the associations between the Big Five personality traits and disordered eating.

Management of eating disorders for people with higher weight: clinical practice guideline

INTRODUCTION

The prevalence of eating disorders is high in people with higher weight. However, despite this, eating disorders experienced by people with higher weight have been consistently under-recognised and under-treated, and there is little to guide clinicians in the management of eating disorders in this population.

AIM

The aim of this guideline is to synthesise the current best practice approaches to the management of eating disorders in people with higher weight and make evidence-based clinical practice recommendations.

METHODS

The National Eating Disorders Collaboration Steering Committee auspiced a Development Group for a Clinical Practice Guideline for the treatment of eating disorders for people with higher weight. The Development Group followed the 'Guidelines for Guidelines' process outlined by the National Health and Medical Research Council and aim to meet their Standards to be: 1. relevant and useful for decision making; 2. transparent; 3. overseen by a guideline development group; 4. identifying and managing conflicts of interest; 5. focused on health and related outcomes; 6. evidence informed; 7. making actionable recommendations; 8. up-to-date; and, 9. accessible. The development group included people with clinical and/or academic expertise and/or lived experience. The guideline has undergone extensive peer review and consultation over an 18-month period involving reviews by key stakeholders, including experts and organisations with clinical academic and/or lived experience.

RECOMMENDATIONS

Twenty-one clinical recommendations are made and graded according to the National Health and Medical Research Council evidence levels. Strong recommendations were supported for psychological treatment as a first-line treatment approach adults (with bulimia nervosa or binge-eating disorder), adolescents and children. Clinical considerations such as weight stigma, interprofessional collaborative practice and cultural considerations are also discussed.

CONCLUSIONS

This guideline will fill an important gap in the need to better understand and care for people experiencing eating disorders who also have higher weight. This guideline acknowledges deficits in knowledge and consequently the reliance on consensus and lower levels of evidence for many recommendations, and the need for research particularly evaluating weight-neutral and other more recent approaches in this field.

Inpatient Rehabilitation during Intensive Refeeding in Severe Anorexia Nervosa

Severe forms of anorexia nervosa are responsible for weight loss and life-threatening consequences. Refeeding represents a real psychiatric and somatic challenge. Physical activities are usually not recommended during intensive refeeding in order to avoid energy expenditure. This study assessed the interest in an early return to controlled physical activities, during a hospitalization in a Physical Medicine and Rehabilitation (PMR) department, including continuous nasogastric refeeding and psychiatric care. A total of 37 subjects aged 32 ± 11 years old performed inpatient physical activities during nasogastric refeeding initiated after intensive care. The physical activity program was adapted according to the hyperactivity of the patients. Evaluation parameters were weight, body mass index (BMI), body composition (fat, lean, and bone masses), and function (strength, balance, walking, ventilation). Patient satisfaction, re-hospitalizations, and physical activities continuation were assessed at 12 months of follow-up. Weight, BMI, and body fat increased significantly (+2.7 ± 1.7 kg; +1.0 ± 0.6 kg/m²; +1.7 ± 2.5 kg, respectively). Muscle strength increased even if the lean mass did not. Walking distance, balance, and respiratory function were significantly improved. Weight and fat mass gains did not differ according to the presence or absence of hyperactivity. At 12 months, 46% of the patients continued to be physically active, but 21% of the patients had been re-hospitalized. The early return to controlled physical activities in PMR hospitalization does not compromise the efficiency of intensive refeeding in severe anorexia nervosa patients.

Benefits of Exercise in Multidisciplinary Treatment of Binge Eating Disorder in Adolescents with Obesity

Obesity in childhood and adolescence represents a serious health problem worldwide. Similarly, eating disorders (EDs) are complex diseases that affect adolescents with an increasing prevalence and are an alarming health concern to both physical and mental health. Traditionally, obesity and EDs, particularly binge eating disorder (BED), have been considered separate conditions, but there is emerging evidence such as etiology, comorbidities, risk factors, psychosocial impairment, and prevention approaches, highlighting important overlaps among these conditions. In youth, the two conditions share risk factors and consequences at both the physical and psychological levels, requiring special care. Exercise, useful as strategy to prevent and treat overweight conditions, may have beneficial effects on BED symptoms, suggesting that it may be considered as one of the key factors in the treatment of individuals affected by obesity with BED. The purpose of this narrative review is to examine the bidirectional impact of obesity and BED in adolescents, in terms of risk factors, etiology and comorbid conditions. Specifically, we focused on the benefits of physical activity (PA) in the multidisciplinary treatment of subjects affected by obesity with BED. Even though additional research is needed to reach conclusions about the role of exercise in the treatment of obesity and comorbid BED, especially in adolescents, promising results have already suggested that closely monitored exercise is safe and, paired with cognitive behavioral therapy, may provide multiple benefits on both the physical and psychological levels. Tailored and integrated treatments for weight management and eating disorders are important to promptly and effectively treat obese subjects that have BED.

A systematic review of treatment approaches for compulsive exercise among individuals with eating disorders

Individuals with eating disorders often experience compulsive exercise which, if left untreated, can lead to longer treatment and worsened symptoms. Compulsive exercise must be addressed within eating disorder treatment to help individuals establish a healthy relationship with exercise. However, there are currently no standardized guidelines for treating compulsive exercise or a consensus on which forms of treatment are most effective. Therefore, the purpose of this review was to examine interventions that address compulsive exercise and their impact on treating compulsive exercise among individuals with eating disorders. A systematic review of the literature was conducted. Eleven studies testing treatments for compulsive exercise were included in this review. Participants were diagnosed with anorexia nervosa, bulimia nervosa, or EDNOS, and a small portion had BED. Improvements in compulsive exercise and eating psychopathology were observed across all studies. The interventions focused on exercise psychoeducation and often incorporated exercise sessions. The findings highlight the positive impact of treating compulsive exercise, suggesting it should be a standard component of eating disorder treatment. Future studies should examine differences in treatment approaches and outcomes specific to each eating disorder, and specific to males. More consistency across studies in the conceptualization and measurement of compulsive exercises is also needed.

Eating Disorders & the Primary Care Physician

Eating disorder is a term to describe a wide variety of maladaptive eating patterns and becoming more prominent in today's culture. The primary care provider (PCP) plays a key role in detection of eating disorders. Medical management by an informed provider is an essential part of the treatment team and focuses on preventing acute and chronic physical sequela of the disease. There are various levels of care offered, with family-based approaches showing the best outcomes.

[Physical Activity in the Prevention and Treatment of Eating Disorders]

Physical Activity in the Prevention and Treatment of Eating Disorders Abstract. On the one hand, excessive or insufficient physical activity is a phenomenological feature and an important etiological factor in eating disorders. On the other hand, healthy and adaptive physical activity has the potential to support the effectiveness of preventive and therapeutic interventions for eating disorders. Research findings confirm the usefulness of interventions focusing on physical activity as an add-on to psychotherapy. Professionally planned and accompanied interventions of this kind are not counterproductive or dangerous but can have a positive effect on the treatment outcome. The current state of research allows a preliminary formulation of guidelines to embed physical activity interventions into evidence-based treatment approaches. The focus of such interventions lies on the reduction of unhealthy, excessive physical activity and the promotion of flexible physical activity.

Treatment Considerations for Compulsive Exercise in High-Performance Athletes with an Eating Disorder

Compulsive exercise is linked with poorer treatment outcomes in people with eating disorder (EDs). High-performance athletes represent a growing and complex subcomponent of the broader ED population, and emergent evidence indicates that different conceptualisations of compulsive exercise are needed in this population. Existing randomised controlled trials in ED populations have demonstrated small treatment effects on compulsive exercise compared with control groups; however, athletes were sparsely sampled across these studies. Thus, the extent to which current treatments for compulsive exercise in EDs are also effective in high-performance athletes is unknown. For this opinion paper, we sought representation from high-performance sports leadership, someone with lived experience of both an ED and high-performance athletics, and ED clinical experts. We discuss the utility of recommending exercise abstinence in ED treatment with athletes, as well as a number of other treatment strategies with some evidence in other contexts for further consideration and research in this population. These include using mindfulness-based interventions as an adjunct to cognitive-behavioural therapies, using wearable technologies and self-reported fatigue to inform training decisions, and incorporating greater exercise variation into training programs. We also offer practical considerations for clinicians seeking to apply foundational elements of cognitive-behavioural interventions (e.g., exposure and response prevention, cognitive restructuring, behavioural experiments) into an ED treatment program for a high-performance athlete. Future research is needed to examine characteristics of pathological compulsive exercise in athletes and whether available treatments are both feasible and effective in the treatment of compulsive exercise in athletes with an ED.

Considerations for Athletes with Eating Disorders Based on Levels of Care

ABSTRACT

This article provides an overview of levels of care for eating disorders (EDs) and considerations that are specific to elite athletes. We discuss the following levels of care in terms of ED pathology and treatment aspects that may be unique to athletes: 1) inpatient and residential care, 2) intensive outpatient and partial hospitalization treatment, and 3) outpatient. Illustrative case studies also are presented to highlight distinctions between levels of care and athlete-specific nuances to treatment approaches and health care teams. Finally, we review aspects of return to play plans for elite athletes with EDs.

Vulnerable and Resilient Phenotypes in a Mouse Model of Anorexia Nervosa

BACKGROUND

Increased physical activity is a common feature of anorexia nervosa (AN). Although high activity levels are associated with greater risk of developing AN, particularly when combined with dieting, most individuals who diet and exercise maintain a healthy body weight. It is unclear why some individuals develop AN while most do not. A rodent model of resilience and vulnerability to AN would be valuable to research. Dopamine, which is believed to play a crucial role in AN, regulates both reward and activity and may modulate vulnerability.

METHODS

Adolescent and young adult female C57BL/6N mice were tested in the activity-based anorexia (ABA) model, with an extended period of food restriction in adult mice. ABA was also tested in dopamine transporter knockdown mice and wild-type littermates. Mice that adapted to conditions and maintained a stable body weight were characterized as resilient.

RESULTS

In adults, vulnerable and resilient phenotypes emerged in both the ABA and food-restricted mice without wheels. Vulnerable mice exhibited a pronounced increase in running throughout the light cycle, which dramatically peaked prior to requiring removal from the experiment. Resilient mice exhibited an adaptive decrease in total running, appropriate food anticipatory activity, and increased consumption, thereby achieving stable body weight. Hyperdopaminergia accelerated progression of the vulnerable phenotype.

CONCLUSIONS

Our demonstration of distinct resilient and vulnerable phenotypes in mouse ABA significantly advances the utility of the model for identifying genes and neural substrates mediating AN risk and resilience. Modulation of dopamine may play a central role in the underlying circuit.

Relationship between Negative Running Addiction and Eating Disorder Patterns in Runners

Current studies show an increase in the risk of eating disorders in runners. Since it is known that abusive exercise can be both a cause and a consequence of such developments, the main objective of the present study was to examine the risk and possible relationships between negative running addiction (NRA), as measured by the reduced and validated SAS-40 scale, and the tendency to be a compulsive eater (measured by YFAS 2.0), anorexia nervosa (AN), and/or bulimia nervosa (BN) (measured by EAT-40). This study highlights the novelty of researching the level of influence of NRA on each defined eating disorder.

METHOD

A total of 167 Spanish-speaking federated runners in cross-country and track running (42% women and 58% men), with an average age of 24 years and an average BMI of 21 kg/m2, responded to an online questionnaire that asked about sociodemographic data and the Spanish versions of the SAS-40, YFAS 2, YFAS 3, and YFAS 4. Through a quantitative methodology using logistic regressions-the coefficient of determination and Pearson's correlation coefficient-we created a sample analysis that related the significant items of the DSM-V to the results of the questionnaires administered, as well as their relationship with the practice of the sport in question and various variables of the environment.

RESULTS

The rates of CE, AN, and BN were 65, 11.4, and 16.2%, respectively. The tendency towards CE increased with a lower weight (r = 0.156, p < 0.05), not having been overweight in childhood (r = 0.151, p < 0.05), and being a long-distance runner (r = 0.123 p < 0.05). The risk of AN increased with the absence of menstruation for more than 3 months (r = 0.271 p < 0.01), having suffered from childhood obesity (r = 0.213 p < 0.05), and being underweight (r = 0.064 p < 0.05). The risk of BN increased with having suffered from childhood obesity (r = 0.194 p < 0.05), having a higher weight (r = 0.140, p < 0.05), and practicing athletics, especially the relay modality (r = 0.044 p < 0.05).

CONCLUSIONS

A considerable number of runners are at risk of suffering from some type of eating disorder. A significant relationship was observed between long-distance runners and the risk of eating disorders (AN, BN, and CE), and the association is stronger for CE than for AN and BN. Lastly, childhood experiences (such as being obese/a healthy weight) were notorious for increasing the risk of eating disorders. Further studies are needed to research each particular parameter and the relationships between the possible levels of dependence on exercise.

What role can accredited exercise physiologists play in the treatment of eating disorders? A descriptive study

Including exercise alongside other therapeutic approaches may help to address dysfunctional exercise use and improve eating disorder treatment outcomes. However, traditional treatment teams often lack the expertise needed to safely prescribe exercise. The aims of this study were to explore the perceptions and experiences of Accredited Exercise Physiologists (AEPs) relating to working with clients diagnosed with eating disorders to identify the role they play in the treatment of eating disorders and identify future training needs. Individual semi-structured telephone interviews were conducted with 12 (n = 9 females) AEPs working in the eating disorders field. Thematic analysis was conducted to extract major themes from the interview transcripts. Five major themes were identified: (1) The role of AEPs in the treatment of individuals with eating disorders is comprehensive; (2) Treatment is more effective when all components are addressed; (3) The absence of therapeutic exercise within standard treatment protocols reflects limitations of traditional scope of practice and knowledge about the role of AEPs; (4) Methods of acquiring further knowledge are insufficient for those in current practice; and (5) Accredited comprehensive training is currently unavailable but needed. This qualitative study showed that AEPs believe they can play a major role in the treatment of eating disorders and that treatment outcomes for individuals are likely to be greatly enhanced when dysfunctional exercise is addressed. Multidisciplinary training is needed.

The neurostructural and neurocognitive effects of physical activity: A potential benefit to promote eating disorder recovery

Accumulating evidence suggests that supervised and adapted physical activity provides cognitive benefits for individuals with eating disorders (EDs). The mechanisms underlying the benefits of physical activity are poorly understood. Addressing this knowledge gap may inform the appropriate integration of structured physical activity into eating disorders treatment and recovery. We draw attention to recent findings in the study of the impact of physical activity on the brain, and we describe the neurostructural and neurocognitive changes associated with physical activity observed in various clinical and nonclinical populations. Considering the identified impairment in brain volume- and/or neurocognitive function in various EDs, we propose that positive effects of physical activity may play a meaningful role in successful ED treatment. Accordingly, we outline research steps for closing the knowledge gap on how physical activity may aid in ED recovery, and emphasize the need to combine measures of cognitive and behavioral responses to physical activity, with technology capable of measuring changes in brain structure and/or function.

Trauma-informed exercise for women survivors of sexual violence

Compared to their male counterparts, women experience alarmingly high rates of sexual violence (SV). Nearly 20% of women in the USA have been victims of SV, and prevalence of sexual assault among female service members is reported to be even higher, up to 50%. SV results in negative health outcomes like posttraumatic stress disorder, depression, obesity, poor body image, and pain-related disability. Exercise has been shown to positively impact both mental and physical health outcomes in populations experiencing posttraumatic symptoms, yet women survivors of SV are often excluded from exercise trials in trauma-affected populations. The purpose of this paper is to comment on the importance of incorporating women-specific trauma-informed principles in the content and delivery of exercise interventions in trauma-affected populations, particularly as it relates to SV. Researchers discuss the implications of female-specific and trauma-informed exercise considerations for SV survivors. This commentary highlights the need for trauma-informed implementation efforts and outcome measurements in exercise interventions involving women affected by SV. Researchers call for (a) increased qualitative work on trauma-specific implementation efforts across exercise intervention domains and (b) increased assessment of trauma-specific outcomes in exercise trials.

Psychosocial etiology of maladaptive exercise and its role in eating disorders: A systematic review

OBJECTIVE

Although maladaptive exercise (ME) is widely recognized as a clinical feature in transdiagnostic eating disorders, less is known about psychosocial factors that give rise to and perpetuate this behavior. This systematic review aimed to examine the empirical status of this association.

METHOD

We reviewed 46 full text articles examining longitudinal associations between psychosocial variables and ME.

RESULTS

Eighteen studies met full inclusion criteria. Based on our qualitative synthesis, evidence suggests reasonably consistent associations between early concern with weight and shape, and negative affect on later development of ME.

DISCUSSION

Inconsistent and insufficient assessment of ME across a majority of studies underscores caution in interpretation of results, but guides important discussion for future clinical and research efforts.

Relationship between physical activity intensities and drunkorexia severity among first-year college students

Investigate the relationship between intensities of physical activity and severity of drunkorexia behaviors. Participants: First-year college students living in residence halls (n = 127) completed an online survey comprising drinking, drunkorexia, and physical activity. Methods: Multiple hierarchical linear regressions were implemented to examine if physical activity intensity correlates to drunkorexia severity. Results: Vigorous physical activity was the only physical activity intensity significantly associated with severity of drunkorexia behaviors. Conclusions: First-year college students' duration of vigorous physical activity in relation to severity of drunkorexia behaviors may vary contingently on the motivation for vigorous physical activity. Practitioners need to consider physical activity can be a co-occurring risk behavior in combination with alcohol misuse.

Commentary on Vulnerability and Resilience to Activity-Based Anorexia and the Role of Dopamine

Activity-based anorexia (ABA) is a commonly used rodent model of anorexia nervosa that is based on observations made in rats decades ago. In recently published work, we describe using this paradigm to model vulnerability and resilience to anorexia nervosa in mice, where vulnerability is characterized by hyperactivity and life-threatening weight loss and resilience is characterized by adaptation and weight stabilization. Using genetically modified hyperdopaminergic mice, we also demonstrate that increased dopamine augments vulnerability to ABA. Here, we briefly review our findings and discuss how obtaining vulnerable and resilient phenotypes enhances utility of the ABA model for understanding the neurobiological basis of anorexia nervosa. We comment on our dopamine findings and close by discussing implications for clinical treatment.

Attitudes toward physical activity as a treatment component for adolescents with anorexia nervosa: An exploratory qualitative study of patient perceptions

OBJECTIVE

Anorexia nervosa (AN) with compulsive exercise is associated with poor treatment outcomes. This study sought to understand the attitudes of adolescents with AN from various stages of treatment, toward physical activity research practices and physical activity as a component of treatment.

METHOD

Seventeen adolescents 12-18 years old (15 female) with AN (10 with acknowledged history of compulsive exercise) were recruited from a Canadian Tertiary Care Hospital's Eating Disorder Program. Six inpatients, 5-day program patients, and six outpatients treated by either the inpatient and/or day treatment program in the past 2 years completed individual, semi-structured interviews that were audio-recorded and transcribed. Results were analyzed deductively using qualitative techniques.

RESULTS

Participants recognized both benefits (psychological, sociological, and physiological) and risks (trigger negative thoughts, increase competitive behavior) of implementing physical activity into acute AN treatment. Patient characteristics, such as stage of treatment and exercise history, had an impact on participants' perceptions toward physical activity in AN. Participants suggested that the ideal physical activity program would be focused on fun, individualized and progressively integrated, group-based, and directly supported by staff. Although the majority of participants stated that they would wear an activity monitor for research purposes, concerns were voiced regarding compliance and the potential impact on eating disorder symptomatology.

DISCUSSION

Participants overwhelmingly supported the careful implementation of structured physical activity and physical activity psychoeducation into the acute treatment of adolescents with AN. This study allows for the inclusion of patient voices in the conversation surrounding the role of physical activity in AN treatment.

Potential bioelectrical impedance analysis (BIA) parameters in prediction muscle strength in women with anorexia nervosa

OBJECTIVES

The role of physical activity in anorexia nervosa (AN) treatment has been investigated. Muscle strength (MS) reflects physical condition and can predict AN patients' response to this novel treatment approach. This study was intended to find bioelectrical impedance analysis (BIA) parameters that predict AN patients' MS.

METHODS

The study included 42 AN patients and 42 healthy ones in the control group. BIA parameters that predict MS were assessed by dividing AN patients into groups by their hand grip strength test score (higher/lower than 22.5 kg).

RESULTS

The highest accuracy for distinguishing AN subjects from the control group was achieved by cell membrane capacitance (AUC = 0.916), impedance at 200 kHz and 5 kHz ratio (AUC = 0.924), phase angle (PA) 5 kHz (AUC = 0.906) and PA 50 kHz (AUC = 0.919). The low MS group had significantly lower values of PA 50 kHz (mean: 4.03 ± 0.80° vs. 4.58 ± 0.65°; p = 0.032) and fat-free mass index (mean: 12.22 ± 1.41 kg/m² vs. 13.14 ± 0.94 kg/m²; p = 0.026). In the univariate model, PA 50 kHz ≥4.037° was associated with the lowest chance of muscle weakness (OR = 0.230; p = 0.005). In the multivariate analysis, PA 50 kHz was the only significant factor of MS (OR = 0.01; p = 0.027).

CONCLUSIONS

PA 50 kHz is the best BIA parameter to predict MS in AN patients. It could be useful for assessment before physical activity treatment application.

Physical activity behaviors and attitudes among women with an eating disorder: a qualitative study

BACKGROUND

Physical activity (PA) is an integral part of healthcare for the general population and individuals with psychiatric disorders. However, PA is significantly more complex for and related to both healthy (e.g., reduced anxiety and depressive symptoms) and unhealthy outcomes (e.g., intrusive, repetitive thoughts that lead to abnormally high levels of PA) among women with an eating disorder (ED). Consequently, many healthcare professionals recommend abstinence from PA during ED treatment. Despite this, women may remain engaged in PA during ED treatment or resume PA shortly thereafter. Little has been done to understand women's PA behaviors and attitudes and to explore how they integrate PA into their lives during and after ED treatment. Thus, this study sought to explore PA behaviors and attitudes among women with an ED.

METHODS

Nine women who self-reported receiving an ED diagnosis participated in semi-structured interviews, which were transcribed and analysed thematically.

RESULTS

Six interrelated themes were constructed to represent participants' PA experiences: PA as a lifestyle, PA can be beneficial, How I feel when I can't do PA, Being cautious about PA, Reactions to healthcare professionals' practice of recommending abstinence from PA during ED treatment, and PA programming thoughts.

CONCLUSIONS

Overcoming dysfunctional PA behaviors (e.g., engaging in abnormally high levels of PA) and attitudes (e.g., associating PA with caloric expenditure) can be a long and complicated journey for women with an ED. Nevertheless, women with an ED want PA to be integrated into their ED treatment protocol for two key reasons, namely to accrue the benefits associated with PA and to learn how to engage in PA in adaptive and healthy ways.

Treatment of compulsive exercise in eating disorders and muscle dysmorphia: protocol for a systematic review

BACKGROUND

Compulsive exercise is a core feature of both eating disorders and muscle dysmorphia. Earlier models of treatment recommended complete abstinence from exercise in eating disorder populations, but recent guidelines advocate for the gradual inclusion of healthier forms of exercise into an overall treatment plan where appropriate. Given the association between problematic exercise behaviour and poorer prognosis, there has been a recent upsurge in the number of treatment interventions for compulsive exercise in eating disorders. However, no systematic review has been published summarising this existing treatment literature. The aim of this review is to determine the efficacy of existing treatments for compulsive exercise in eating disorders and muscle dysmorphia.

METHODS

A systematic review will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five electronic databases (PsycInfo, MEDLINE, Embase, Web of Science, and Scopus) will be searched from database inception until November 2020. We will include studies that: (a) sampled adolescents and/or adults with either an eating disorder or muscle dysmorphia; (b) assessed changes in compulsive exercise from pre- to post-intervention; and (c) used a standardised instrument to measure compulsive exercise or related constructs. We will include studies with a comparison group (e.g., randomised controlled trials) and without a comparison group (e.g., pilot studies and case studies) to provide a comprehensive overview of the literature. One reviewer will screen all titles and abstracts against eligibility criteria, with 20% of excluded articles cross-referenced by another reviewer. Full texts will be obtained for articles deemed relevant or where inclusion was uncertain, and will be screened by both reviewers. We will also evaluate the quality of the included studies using a modified Downs and Black (J Epidemiol Community Health 52:377-384, 1998) assessment checklist.

DISCUSSION

Results from this review will help to determine the most efficacious treatment components for compulsive exercise in eating disorders and muscle dysmorphia. We hope that our results will help inform clinical practice guidelines in recommending targeted interventions for the treatment of compulsive exercise.

Validation of the Intuitive Exercise Scale in Patients With Eating Disorders

Unhealthy cognitive–emotional relationships with exercise can hinder positive treatment outcomes when left unaddressed. However, clinicians lack validated tools to monitor this aspect of treatment. This study examined the 14-item Intuitive Exercise Scale with 165 patients in the United States (Mage = 26.48 years) who were receiving treatment for an eating disorder. The original factor structure was inadequate for the current sample, and exploratory factor analysis generated three factors—emotional exercise, body intuition, and exercise variety. The three-factor solution yielded strong internal consistency and partial support for the scale’s validity. Furthermore, patients scored lowest in body intuition, confirming low awareness of bodily cues common in patients with eating disorders. This study informs how clinicians may integrate and monitor patients’ cognitive–emotional relationship with exercise as part of holistic and intuitive eating disorder treatment approaches.

The relationship between food addiction and patterns of disordered eating with exercise dependence: in amateur endurance athletes

PURPOSE

Examine the prevalence and potential relationships among food addiction (FA)-as measured by Yale Food Addiction Scale 2.0 (YFAS 2.0), eating disorders (ED)-as measured by Eating Disorder Diagnostic Scale (EDDS)-and exercise dependence (EXD)-as measured by Questionnaire to Diagnose Exercise Dependence in Endurance Sports (FESA), for the first time worldwide, in amateur endurance athletes.

METHODS

A total of 1022 German-speaking endurance athletes (44% male, Ø 36 years, Ø BMI 23 kg/m²) replied to an online questionnaire consisting of demographics, related parameters, and the German versions of YFAS 2.0, EDDS, and FESA.

RESULTS

Prevalence of FA, ED, and EXD was 6.2, 6.5, and 30.5%. The probability for FA increases with BMI, thoughts about food and EXD score, and decreases with age and when an ED is present. People with FA and people with ED vs. people with both, FA&ED, differed significantly in this cohort. Strong significant relationships were found between FA and EXD (X² (1) = 15.117, p < 0.001, n = 1022).

CONCLUSIONS

A considerable number of amateur endurance athletes may suffer from FA. The association between FA and EXD is stronger than between ED and EXD, indicating FA as a potentially more relevant subject-than ED-for prevention or therapy in people with EXD. Further studies are needed to investigate parameters and relationships between the possibly involved types of ED, FA, and EXD.

Development and evaluation of an adapted physical activity program in anorexia nervosa inpatients: A pilot study

BACKGROUND AND CONTEXT

Problematic use of physical activity is frequent in subjects with anorexia nervosa (AN). Although it increases resistance to therapeutic treatment, paradoxically, physical activity in AN can also improve mental and physical health. Based on the literature review we hypothesized that adding an adapted physical activity (APA) program to treatment programs could be more beneficial than a total suppression of physical activities. We designed this open study to evaluate the outcome of AN inpatients after an APA program implementation as well as the perceived effect of APA.

METHOD

Forty-one women with AN (17.2 (±2.5) years old, BMI of 16.86 (±2.0)) were included. An eight-session (1 h30/session/week) standardized APA program was delivered and evaluated by structured questionnaires assessing exercise dependence, perceived physical activity, eating disorder (ED) symptoms, body mass index (BMI), along with an interview before and after the APA program.

RESULTS

Twenty-nine women complete the PA program and evaluation. BMI and perceived PA score significantly increased, ED and exercise dependence scores significantly decreased (p < .01). Participants appreciated the program.

DISCUSSION/CONCLUSION

The inpatient program which included APA program helped AN inpatients in decreasing their ED symptoms and their dependence to PA, without any deleterious effect on BMI. Furthermore, APA was appreciated by participants.

Eating-Disordered Behavior in Adolescents: Associations with Body Image, Body Composition and Physical Activity

Eating disorders (EDs) represent a disparate group of mental health problems that significantly impair physical health or psychosocial functioning. The aim of this study was to present some evidence about the prevalence of eating-disordered behavior (EDB) in adolescents, and explore its associations with body image (BI), body composition (BC) and physical activity (PA) in this age group. Data from 780 adolescents participating in a health behavior in school-aged children (HBSC) study conducted in Slovakia in 2018 were used (mean age 13.5 ± 1.3; 56% boys). Differences in mean values of numerical indicators were evaluated using the independent samples t-test. Differences between nominal variables were assessed by the chi-square test. Pearson correlation was used to describe the associations between all the selected variables. EDB was positively screened in 26.7% (208/780) of adolescents, with a higher prevalence in girls (128/344, 37.2%) than in boys (80/436, 18.3%). Significantly higher means of BI, body weight (BW), body mass index (BMI), body fat mass (BFM), body fat percentage (BFP), body fat mass index (BFMI), fat free mass index (FFMI), and SCOFF questionnaire score (SCOFF QS) were found in those positively screened for EDB. Pearson correlation analysis revealed positive associations between EDB and BI, BW, BMI, BFM, BFP and BFMI. The prevalence of EDB is high in Slovak adolescents. Positive associations between EDB, BI, BMI and fat-related body composition parameters support the idea of a more integrated approach in EDs and obesity prevention and treatment. At the same time, gender differences suggest the need for considering gender-specific strategies aimed at girls and boys separately.

Mental Health Issues and Psychological Factors in Athletes: Detection, Management, Effect on Performance, and Prevention: American Medical Society for Sports Medicine Position Statement

The American Medical Society for Sports Medicine convened a panel of experts to provide an evidence-based, best practices document to assist sports medicine physicians and other members of the athletic care network with the detection, treatment, and prevention of mental health issues in competitive athletes. This statement discusses how members of the sports medicine team, including team physicians, athletic trainers, and mental health providers, work together in providing comprehensive psychological care to athletes. It specifically addresses psychological factors in athletes including personality issues and the psychological response to injury and illness. The statement also examines the athletic culture and environmental factors that commonly impact mental health, including sexuality and gender issues, hazing, bullying, sexual misconduct, and transition from sport. Specific mental health disorders in athletes, such as eating disorders/disordered eating, depression and suicide, anxiety and stress, overtraining, sleep disorders, and attention-deficit/hyperactivity disorder, are reviewed with a focus on detection, management, the effect on performance, and prevention. This document uses the Strength of Recommendation Taxonomy (SORT) to grade level of evidence.

Patients' views on a new treatment for Bulimia nervosa and binge eating disorder combining physical exercise and dietary therapy (the PED-t). A qualitative study

A new group based treatment for patients with bulimia nervosa (BN) and binge eating disorder (BED), combining guided Physical Exercise and Dietary therapy (PED-t), has shown the capacity to alleviate BN and BED symptoms. The PED-t is run by therapists with a professional background in sport sciences and nutrition, which in many clinical settings is an uncommon group of professionals. The symptom reduction effects using the PED-t need validation from patients who have been given this kind of treatment, as negative experiences may impinge further clinical implementation. To explore such experiences, semistructural interviews were conducted with 15 participants. The interviews were transcribed and analyzed using a systematic text condensation approach. Overall, patients experienced the format and content of the PED-t as beneficial and as providing tools to manage BN- and BED symptoms. The patients' experiences of therapist credibility was enhanced by their appreciation of the therapists' professional background. Finally, some treatment modifications were suggested. Overall, the PED-t may thus be offered to patients with BN and BED, by a new set of professionals, and in uncommon settings. This possibility calls for future effectiveness studies integrating both parametric and experiential data.

Clinical guidance on osteoporosis and eating disorders: the NEDA continuing education series

Osteoporosis is a common and very serious complication of anorexia nervosa. It affects these patients, both males and females, at very young ages. This loss of bone mineral density begins quickly, soon after the onset of the eating disorder. It is one of the rare medical complications of anorexia nervosa which may result in irreparable harm, even if there is successful nutritional rehabilitation and weight restoration. Nevertheless, notwithstanding its high importance, there is a paucity of evidence-based medicine to guide the optimal approach to diagnosis, prevention, and treatment. This paper attempts to inform clinicians taking care of these patients about a reasonable and measured approach to this problem, while the field awaits more definitive medical literature.

Nutritional Management and Outcomes in Malnourished Medical Inpatients: Anorexia Nervosa

BACKGROUND

Anorexia Nervosa (AN) is a psychiatric disorder characterised by a physical and psychosocial deterioration due to an altered pattern on the intake and weight control. The severity of the disease is based on the degree of malnutrition. The objective of this article is to review the scientific evidence of the refeeding process of malnourished inpatients with AN; focusing on the clinical outcome.

METHODS

We conducted an extensive search in Medline and Cochrane; on April 22; 2019; using different search terms. After screening all abstracts; we identified 19 papers that corresponded to our inclusion criteria.

RESULTS

The article focuses on evidence on the characteristics of malnutrition and changes in body composition; energy and protein requirements; nutritional treatment; physical activity programmes; models of organisation of the nutritional treatment and nutritional support related outcomes in AN patients.

CONCLUSION

Evidence-based standards for clinical practice with clear outcomes are needed to improve the management of these patients and standardise the healthcare process.

Clustered Patterns of Behavioral and Health-Related Variables Among Young Lesbian Women

Lesbian women are at increased risk for a variety of mental and physical health problems compared to heterosexual women. In order to inform treatment and prevention, the purpose of this study was to examine behavioral and health-related patterns among lesbian women and elucidate how these patterns are associated with general discrimination, sexual minority stress, affect, and social support. A sample of self-identified lesbian women (N = 436) completed an online survey from August 2014-March 2015. A latent profile analysis was conducted using measures of body mass index, hazardous alcohol use, binge eating, eating disorder risk, and exercise as indicators. A 5-class solution best fit the data and included two healthy groups: (a) low health risk, moderate exercise (54%), (b) low health risk + high exercise (22%); and three unhealthy risk groups: (c) obese + binge eating (14%); (d) disordered eating + hazardous alcohol use (5%); (e) disordered eating + high exercise (5%). The three unhealthy classes generally reported more general discrimination, sexual minority stress, social anxiety, negative affect, and lower social support compared to the healthy classes. These findings show that behavioral and health-related variables cluster together in several distinct patterns among lesbian women. In addition, general discrimination and sexual minority stress and associated psychosocial functioning may be related to these maladaptive behavioral and health-related patterns and may be important to consider in behavioral interventions.

Novel approaches for the assessment of relative body weight and body fat in diagnosis and treatment of anorexia nervosa: A cross-sectional study

BACKGROUND & AIMS

Anorexia nervosa (AN) is a severe psychosomatic disease that seriously affects nutritional status. Therapeutic approaches primarily aim for rapid weight restoration by high caloric diets and activity restriction. This often promotes abdominal body fat gain, which potentially negatively influences the patient's compliance and increases the risk of relapse. This study focused on the evaluation of body weight and subcutaneous adipose tissue (SAT) in AN patients by novel approaches.

METHODS

The SAT of AN patients (n = 18, body mass index (BMI) 15.3 ± 1.3 kg/m²) was determined by a highly accurate and reliable ultrasound method. The sum of SAT thicknesses of eight sites (D_INCL) was calculated. Individual metabolic profiles were analyzed. The mass index (MI), which considers body proportions, was used in addition to BMI. Additional to the standard laboratory diagnostics, dermal carotenoids measured by resonance Raman spectroscopy, leptin, and oxidative stress indicators were determined.

RESULTS

The mean MI was 15.7 ± 1.4 kg/m². The D_INCL considerably differed between individuals with the same BMI. Half of the patients (Group 1) had low D_INCL: 1.3-28.4 mm, and Group 2 showed values up to 58.2 mm (corresponding to approximately 6 kg SAT mass). The two group means differed by more than 300% (P < 0.001). Accordingly, leptin levels significantly differed (P < 0.001). Mean SAT thicknesses were significantly higher in Group 2 at all eight sites. The groups also significantly differed in two oxidative stress parameters: total antioxidative capacity, malondialdehyde-modified low density lipoprotein immunoglobulin M (MDA-LDL IgM), and in the carotenoid level.

CONCLUSION

Half of the patients had sufficiently high fat mass, despite very low BMI. Consequently, their muscle (and other organ) masses must have been extremely low. Diagnostic criteria and treatment protocols for AN should consider each patient's body composition. In addition to dietary treatments, muscle training at low energy turnover rates may be essential for avoiding unnecessary body fat gain, better treatment results, and long-term recovery.
