Disordered eating behaviours during the menopausal transition: a systematic review

Disordered eating refers to a range of eating behaviours and attitudes towards weight and food that can negatively influence physical and psychosocial well-being. The menopausal transition could be a vulnerable period for disordered eating due to major hormonal fluctuations, menopausal symptoms, common body composition shifts, and an increased risk of psychological challenges. This systematic review aimed to summarize evidence on the associations between the menopausal transition and disordered eating. Records published before October 2023 were identified through MEDLINE, PsycINFO, Scopus, Embase, and CINAHL. Studies investigating associations between menopausal status, menopausal symptoms, or reproductive hormone levels, and disordered eating during the menopausal transition were sought. A total of 1301 non-duplicate records were screened, with 10 studies deemed eligible for inclusion. Most included studies used a cross-sectional design (n = 9). Findings include potentially higher levels of binge eating during the perimenopausal stage, whereas restrictive eating behaviours appeared more common during postmenopause compared to premenopause. Both studies investigating menopausal symptoms found strong positive associations with disordered eating. Nonetheless, findings are equivocal with contrasting results and limited methodological quality across studies. Further research is needed to verify these findings and better assist health professionals in supporting healthy eating behaviours in menopausal women during this complex transition.

Dietary intake of adults with eating disorders: A systematic review and meta-analysis

Studies have confirmed the link between altered dietary intake and eating disorders (EDs), although no systematic assessment of this research exists. Rigorous synthesis of dietary intake in anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), and similar EDs is needed to explore similarities and differences. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we conducted a systematic review and quantitative synthesis of studies of dietary intake. Searches of three electronic databases resulted in thirty-nine included studies. Meta-analyses of subsets of these studies were undertaken to summarise macronutrient intake across AN, BN, and BED. Study quality was assessed using the American Academy of Nutrition and Dietetics Quality Criteria Checklist, with ratings either Positive (k = 27) or Neutral (k = 12). Adults with AN had low energy intake and those with BED reported elevated macronutrient intake. Individuals with BN reported wide variation in energy intake, including some of the highest estimates. Individuals with AN were likely to under-consume key micronutrients, with sodium potentially over-consumed in BN and BED. Vitamin D was under-consumed across all disorders. This meta-analysis highlights important diagnostic differences and synthesises dietary intake in EDs, with particular relevance to risk assessment and treatment.

Exploring the Experiences and Perspectives of Division III Athletes Regarding Personalized Nutrition Plans for Improved Performance-A Qualitative Investigation

(1) Background: This qualitative study explores Division III college student-athletes' experiences and perceptions of personalized nutrition plans in collegiate sports settings. (2) Methods: Semi-structured interviews were conducted using a general qualitative research design. Using a grounded theory approach, a thematic analysis was utilized to analyze the interview transcripts, allowing for the identification of recurring themes and patterns. (3) Results: A total of 30 Division III college student-athletes, 16 males (53.3%) and 14 females (46.7%), representing a diverse range of sports disciplines, engaged in discussions about personalized nutrition plans. Analysis of the data revealed five main themes: (1) Nutritional Knowledge and Awareness, (2) Perceived Benefits of Personalized Nutrition Plans, (3) Challenges and Barriers to Implementation, (4) Influence of Team Culture and Environment, and (5) Suggestions for Improvement. (4) Conclusion: This study sheds light on the complexities of implementing personalized nutrition plans in collegiate sports settings and emphasizes the need for comprehensive, athlete-centered approaches to optimize performance and well-being.

Tuning in to recovery: influence of music on emotional well-being during mealtime in inpatient facilities for eating disorders

BACKGROUND

In rehabilitating eating disorders (ED), mealtimes are critical but often induce stress, both for restrictive and binge-purge disorders. Although preliminary data indicate a positive effect of music during mealtime, few studies employ an experimental approach. This study examines the influence of background music during mealtime in an inpatient ward setting, offering a real-world perspective.

METHODS

Fifty-one women diagnosed with ED participated in this within-subjects study. Over two weeks, during lunch and dinner, they were exposed to three randomized music conditions: no music, focus piano music, and pop music. The self-report questionnaires captured affective states, noise levels, and hunger, while trained dietitians recorded food consumption and eating rituals.

RESULTS

The absence of music led to an increase in uneaten food (p = 0.001) and the presence of eating rituals (p = 0.012) during mealtimes. Significantly, only silence during mealtime reduced positive emotional states, while background music maintained positive emotions (p < 0.001). No specific differences emerged between the two types of music (focus piano and pop).

CONCLUSIONS

These findings affirm the positive impact of background music during mealtime in real-world settings, enhancing the potential of inpatient eating rehabilitation programs for individuals with ED. More studies are needed to validate and extend these results, particularly in outpatient settings.

Effects of mealtime assistance in the nutritional rehabilitation of eating disorders

PURPOSE

The aim of the study was to examine the effects of meal supervision, provided by health professionals, volunteers or family members, on anthropometric, nutritional, psychological, and behavioural outcomes in patients with eating disorders (EDs).

METHODS

The present systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The last search was conducted in three databases (PubMed, Scopus, and the Cochrane library). Inclusion criteria considered paediatric and adult patients suffering from EDs, regardless of ethnicity, and treated in different therapeutic settings. The quality of the studies was evaluated using the Newcastle Ottawa Scale (NOS) adapted for cross-sectional studies and Version 2 of the Cochrane risk-of-bias assessment tool for randomised trials.

RESULTS

3282 articles were retrieved, out of which only 6 met the eligibility criteria. A marked heterogeneity in definitions and approaches to supervised mealtime was observed. This variability emerged in the methodologies used in the supervised meal, and in the reference values for the outcome measures that were used, such as the analysis of different parameters. Based on these observations, mealtime assistance provided to patients with EDs shows an overall positive effect on eating behaviour and dysfunctional attitudes. Future research should be prompted to provide a thorough definition of a structured procedure for meal assistance to be potentially and systematically included in the nutritional rehabilitation protocols for patients with EDs.

Oral health and individuals with a lived experience of an eating disorder: a qualitative study

BACKGROUND

Limited evidence exists describing the impact to oral health when living with an eating disorder and the availability of information or access to oral health services. This study investigated the perceptions of individuals with a lived experience of an eating disorder specifically to understand their needs and recommendations for improving access to early intervention and oral health promotion.

METHODS

Using purposive sampling a total of 12 semi-structured interviews were conducted with participants across Australia who had a lived experience of an eating disorder. A hybrid inductive and deductive approach to thematic analysis was used to construct salient themes and subthemes.

RESULTS

Most participants had experienced some oral health manifestation as part of their eating disorder hence, many felt quite knowledgeable on the topic. Following their eating disorder many participants felt confident in engaging with dental services, although, barriers including embarrassment, shame, and cost compromised access at times. Participants felt strongly that greater emphasis on oral health promotion during an eating disorder was important and this may be achieved by increasing the availability of resources and using trusted non-dental health professionals like dietitians.

CONCLUSIONS

The need for oral health promotion while experiencing an eating disorder was evident, however, dentists can often be a costly option. Non-dental health professionals like dietitians working with clients with an eating disorder may be an acceptable alternative for closing this gap.

The Impact of Anorexia Nervosa and the Basis for Non-Pharmacological Interventions

Anorexia nervosa is a psychiatric disorder with an unknown etiology that is characterized by an individual's preoccupation with their weight and body structure while denying the severity of their low body weight. Due to the fact that anorexia nervosa is multifaceted and may indicate the coexistence of genetic, social, hormonal, and psychiatric disorders, a description of non-pharmacological interventions can be used to ameliorate or reduce the symptoms of this condition. Consequently, the purpose of the present narrative review is to describe the profile's context in the anorexic person as well as the support they would require from their family and environment. In addition, it is aimed at examining preventative and non-pharmacological interventions, such as nutritional interventions, physical activity interventions, psychological interventions, psychosocial interventions, and physical therapy interventions. To reach the narrative review aims, a critical review was conducted utilizing both primary sources, such as scientific publications, and secondary sources, such as bibliographic indexes, web pages, and databases. Nutritional interventions include nutritional education and an individualized treatment for each patient, physical activity interventions include allowing patients to perform controlled physical activity, psychological interventions include family therapy and evaluation of the existence of other psychological disorders, psychosocial interventions include management of the relationship between the patient and social media and physical therapy interventions include relaxation massages and exercises to relieve pain. All these non-pharmacological interventions need to be individualized based on each patient's needs.

A Qualitative Assessment of the Treatment Needs of Women with Concurrent Eating and Substance Use Disorders in a Residential Setting

Objectives: Eating and substance use disorders (SUD) are generally treated separately, leaving eating disorders (ED) overlooked within substance use treatment. The frequent co-occurrence of SUD and ED is well documented. Despite their many similarities and frequent co-occurrence, these two disorder types continue to be largely treated separately-either sequentially, with the most severe disorder addressed first, or concurrently but in separate programs. Our study, therefore, responds to this lacuna of data on patient and provider treatment needs for integrated ED and SUD treatment, centering the perspectives of women with lived experience of ED and SUD to support the development of therapeutic groups for women in treatment programs. Methods: This study was designed as a needs and assets assessment to determine the needs and priorities of women with concurrent ED and SUD for developing group programs. Participants for the needs assessment included both staff members (n = 10) and women receiving treatment (n = 10) who were recruited from a 90-day residential treatment program for women with SUD in British Columbia, Canada. Interviews and focus groups conducted with participants were audio-recorded and transcribed verbatim. Data were thematically analyzed and coded using Dedoose software. Results: Six key themes emerged from the qualitative data and were organized into sections with sub themes. An overarching premise from both staff and program participants was the need for concurrent therapeutic programming, nutritional support, and medical monitoring. The six discrete themes that were elicited included the similarities between ED and SUD, gaps in treatment, community support, family involvement, program participant treatment suggestions, staff treatment suggestions, and family involvement. Conclusions: Throughout this qualitative study, the need for screening and assessment of both disorders along with integrated treatment was stressed by participants, both program participants and staff alike. These findings complement current literature and suggest that pursuing concurrent treatment design may be helpful in addressing unmet program participant needs and could provide a more holistic framework for recovery.

Women's perspectives toward their nutritional counseling for eating disorders: a qualitative internet-based study in Israel

Nutritional counseling is a central part of eating disorder (ED) treatment. However, the nature of this treatment has not yet been described from women's perspectives. We conducted two studies exploring views of women regarding their ED nutritional counseling. In the first study, we used content analysis to reveal practices that registered dietitians (RDs) use in ED treatment. In the second study, we used phenomenological analysis to explore the nature of the client-dietitian collaboration. Data included 1,897 posts and 8,673 responses from 414 distinct female users, retrieved from a moderated ED Internet community website in Israel. Content analysis demonstrated six practices used by RDs: meal planning, weight monitoring, health assessment/consultation, establishing rapports, food logs, joint eating. Phenomenological analysis produced four positions demonstrating client-dietitian collaborations: "Silent dialogue," "Cancelation and deception," "Tough love," "Containment." Findings revealed women's efforts to continue treatment despite their ambivalence about goals and recovery, and RDs' efforts to help women, despite the women's ambivalence, to move forward toward recovery.

What role do dietitians have in providing nutrition care for eating disorder treatment? An integrative review

BACKGROUND

Dietitians are recognised as experts in nutrition care and essential members of multidisciplinary healthcare teams. However, the role of dietitians in caring for people with eating disorders is not well understood. The present review aimed to identify, critically appraise and synthesise the current evidence exploring the views and experiences of dietitians, other health professionals, patients and carers regarding the role of dietitians in the treatment of eating disorders.

METHODS

CINAHL, MEDLINE, Embase, Scopus and PsycINFO were searched in April 2020 and again in February 2021. Studies were included if they were original research; explored views and experiences of the role of dietitians in the treatment of eating disorders, including perceptions of patients, carers and other health professionals regarding nutrition care for eating disorders; and the full-text article was available in English. Title and abstract screening, full-text screening, quality assessment and data extraction were completed in duplicate. Quality assessment was conducted using the Mixed Methods Assessment Tool. Thematic synthesis was used for data analysis.

RESULTS

Fourteen studies met the inclusion criteria. Quantitative, qualitative and mixed-methods study designs were included. Four themes emerged inductively from the data: (i) dietitians as collaborators, educators and counsellors; (ii) dietitians individualising care and desiring a holistic approach; (iii) opportunities for dietitians to gain confidence; and (iv) experiencing nutrition care as a patient or carer.

CONCLUSIONS

This review suggests that dietitians have a varied role in eating disorder treatment but desire further training. Understanding the training needs of dietitians can identify practice gaps and opportunities to enhance clinician confidence.

Rationale and development of a manualised dietetic intervention for adults undergoing psychological treatment for an eating disorder

PURPOSE

Due to the current dearth of literature regarding dietetic treatment for patients with an eating disorder (ED), no manualised dietetic interventions exist to enable the testing of dietetic treatments in this population. This paper aims to: (1) describe the rationale and development of a manualised dietetic intervention for adults undergoing concurrent psychological treatment for an ED; and (2) provide an overview of the feasibility testing of this intervention.

METHODS

Current best evidence to date for dietetic treatment in EDs was utilised to develop a manualised dietetic intervention for feasibility testing alongside outpatient psychological 'treatment as usual'.

RESULTS

The developed intervention consists of five, dietitian-delivered outpatient sessions: (1) getting started; (2) mechanical eating and dietary rules; (3) estimating portion sizes and social eating; (4) maximising your meal plan and meal preparation; and (5) review and treatment planning as well as pre- and post-intervention assessments.

CONCLUSION

This paper is intended as a resource for clinicians and researchers in the conduct of future studies examining dietetic treatment for patients with an ED.

A review of treatment manuals for adults with an eating disorder: nutrition content and consistency with current dietetic evidence

PURPOSE

This study aimed to summarise the nutrition and food-related content of treatment manuals for adults with eating disorders (EDs) and assess the degree to which this information conforms with current guidelines and literature.

METHODS

Treatment manuals for adults with an ED were identified by conducting an online search of Internet book dealer Amazon and University of Sydney library catalogue as per methods used in previous reviews of self-help patient resources. The nutrition and food-related content of these manuals was extracted and reviewed independently by two reviewers using a criteria based on current best evidence to date regarding dietetic treatment for EDs.

RESULTS

Twenty-two manuals met inclusion criteria, 20 (91%) of which contained some degree of nutrition and food-related content. Two manuals (9%) included content written by a dietitian, six (27%) included citation of dietetic literature to support the recommendations made and eight (36%) recommended a dietitian be consulted as part of a multidisciplinary approach to treatment. Thirteen manuals (60%) contained nutrition and food-related information not substantiated by current evidence.

CONCLUSION

It is common for treatment manuals for EDs to contain nutrition and food-related content. However, most of the authors of the 22 manuals identified did not appear to collaborate with a dietitian in writing this content or cite peer-reviewed literature to substantiate dietary advice given. Consistent with current clinical practice guidelines, greater collaboration between dietitians and clinicians is required to develop, evaluate and disseminate evidence-based approaches to dietetic management.

Virtual Online Home-Based Treatment During the COVID-19 Pandemic for Ultra-Orthodox Young Women With Eating Disorders

Background: With the outbreak of the COVID-19 pandemic, the need arose to maintain treatment continuity for religious Jewish Ultra-Orthodox young women with eating disorders (EDs) previously hospitalized in the ED department at the Ultra-Orthodox "Mayanei Hayeshua" medical center in Israel. This need led to the development of home-based online treatment channels, previously unfamiliar, and unaccepted in this population. The implementation of this model had to take into consideration many of the difficulties inherent in the use of online treatment in Jewish Ultra-Orthodox mental health patients. Aims: We sought to investigate our online home-based treatment model implemented during the COVID-19 pandemic in previously hospitalized young Ultra-Orthodox women with EDs. Method: We briefly review the literature on: (1) The Jewish Israeli Ultra-Orthodox culture; (2) Young women in Ultra-Orthodox society; and (3) EDs in Jewish Israeli Ultra-Orthodox women. We then present the inpatient ED department for Ultra-Orthodox young women and describe the online treatment model adapted to this population during the COVID-19 pandemic. We highlight the difficulties, dilemmas, and advantages of our online model with the description of three patients. Findings: Online therapy can serve as a barrier to treatment in some cases, due to physical (lack of suitable online devices except phones), familial (over-crowded families), and religious circumstances, as well as because of the patients' reluctance to take part in this treatment. In other cases, virtual home-based treatment can lead to a positive change. This may be the case in patients who find the distancing online model suitable for them, and in parents who are committed to treatment, using their greater physical and emotional presence at home during the COVID-19 pandemic for the good if their ill-daughters. Discussion: This paper highlights the difficulties and possibilities inherent in a virtual home-based treatment during the COVID-19 pandemic for Ultra-Orthodox young women previously hospitalized because of an ED. This model can be effective for some patients and families if undertaken by a multidisciplinary team that is not only knowledgeable about the treatment of EDs and the use of online strategies but also knowledgeable and culturally sensitive to the specific needs and codes of Ultra-Orthodox populations.

ANZAED practice and training standards for dietitians providing eating disorder treatment

INTRODUCTION

Dietitians involved in eating disorder treatment are viewed as important members of the multidisciplinary team. However, the skills and knowledge that they require are not well characterised. Therefore, as part of a broader project to identify the key principles and clinical practice and training standards for mental health professionals and dietitians providing eating disorder treatment, the Australia & New Zealand Academy for Eating Disorders (ANZAED) sought to identify the key practice and training standards specific to dietitians. An expert working group of dietitians was convened to draft the initial dietetic standards. After expert review, feedback on the revised standards was then provided by 100 health professionals working within the eating disorder sector. This was collated into a revised version made available online for public consultation, with input received from treatment professionals, professional bodies and consumer/carer organisations.

RECOMMENDATIONS

Dietitians providing treatment to individuals with an eating disorder should follow ANZAED's general principles and clinical practice standards for mental health professionals and dietitians. In addition, they should also be competent in the present eating disorder-specific standards based around the core dietetic skills of screening, professional responsibility, assessment, nutrition diagnosis, intervention, monitoring and evaluation.

CONCLUSIONS

These standards provide guidance on the expectations of dietetic management to ensure the safe and effective treatment of individuals with an eating disorder. Implications for professional development content and training providers are discussed, as well as the importance of clinical supervision to support professional self-care and evidence-informed and safe practice for individuals with an eating disorder.

Outcomes of an inpatient medical nutritional rehabilitation protocol in children and adolescents with eating disorders

BACKGROUND

Medical stabilization through inpatient nutritional rehabilitation is often necessary for patients with eating disorders (EDs) but includes the inherent risk of refeeding syndrome. Here we describe our experience of implementing and sustaining an inpatient nutritional rehabilitation protocol designed to strategically prepare patients with EDs and their families for discharge to a home setting in an efficient and effective manner from a general adolescent medicine unit. We report outcomes at admission, discharge, and 4-weeks follow-up.

METHODS

Protocol development, implementation, and unique features of the protocol, are described. Data were collected retrospectively as part of a continuous quality improvement (QI) initiative. Safety outcomes were the clinical need for phosphorus, potassium, and magnesium supplementation, other evidence of refeeding syndrome, and unexpected readmissions within one month of discharge. The value outcome was length of stay (LOS). Treatment outcomes were the percentage median BMI (MBMI) change from admission to discharge, and from discharge to 4-weeks follow-up visit.

RESULTS

A total of 215 patients (88% F, 12% M) were included. Patients averaged 15.3 years old (5.8-23.2y); 64% had AN, 18% had atypical anorexia (AtAN), 6% bulimia nervosa (BN), 5% purging disorder (PD), 4% avoidant-restrictive food intake disorder (ARFID), and 3% had an unspecified food and eating disorder (UFED). Average LOS was 11 days. Initial mean calorie level for patients at admission was 1466 and at discharge 3800 kcals/day. Phosphorus supplementation for refeeding hypophosphatemia (RH) was needed in 14% of inpatients; full-threshold refeeding syndrome did not occur. Only 3.8% were rehospitalized in the thirty days after discharge. Patients averaged 86.1% of a median MBMI for age and gender, 91.4% MBMI at discharge, and 100.9% MBMI at 4-weeks follow-up. Mean percentage MBMI differences between time points were significantly different (admission-discharge: 5.3%, p <0.001; discharge-follow-up: 9.2%, p <0.001).

CONCLUSIONS

Implementation of the CHOP inpatient nutritional rehabilitation protocol aimed at rapid, efficient, and safe weight gain and integration of caregivers in treatment of patients with diverse ED diagnoses led to excellent QI outcomes in percentage MBMI at discharge and 4-weeks follow-up, while maintaining a short LOS and low rates of RH phosphorus supplementation.

Disordered Eating Behaviors and Food Addiction among Nutrition Major College Students

Evidence of whether nutrition students are free from food-related issues or at higher risk for eating disorders is inconsistent. This study aimed to assess disordered eating behaviors and food addiction among nutrition and non-nutrition major college students. Students (n = 967, ages 18–25, female 72.7%, white 74.8%) enrolled at a public university completed online demographic characteristics surveys and validated questionnaires measuring specific disordered eating behaviors. Academic major category differences were compared. Additionally, high risk participants were assessed by weight status and academic year. Overall, 10% of respondents were a high level of concern for developing eating disorders. About 10.3% of respondents met criteria for food addiction. In addition, 4.5% of respondents had co-occurrence of eating disorder risk and food addiction risk out of total respondents. There were no significant differences in level of concern for developing an eating disorder, eating subscales, or food addiction among academic majors. The percentage of high risk participants was lower in the underweight/normal weight group than in the overweight/obese group in health-related non-nutrition major students but not in nutrition students. Early screening, increasing awareness, and promoting healthy eating habits could be potential strategies to help treat and prevent the development of disorders or associated health conditions in nutrition as well as non-nutrition students.

Pediatric Malnutrition: Putting the New Definition and Standards Into Practice

In recent years, much effort has been directed at redefining malnutrition in the pediatric population to include the acute clinical population in addition to the more traditional ambulatory populations. In 2013, an expert panel convened to perform a critical review of available literature to craft a new approach to malnutrition. Closely thereafter, the Academy of Nutrition and Dietetics and the American Society for Parenteral and Enteral Nutrition published recommended indicators for the identification and documentation of malnutrition in pediatric populations. The purpose of this article is to review the domains within the new definition of malnutrition in pediatric practice, describe populations in which the recommended indicators for identification and management are problematic in clinical practice, give case studies that apply the new definition, and finally describe the implementation of a malnutrition identification program within a large tertiary care children's hospital.

Eating Disorders: Cultural Model and Consensus Regarding Food

The cultural model of food was applied to 112 adult patients with eating disorders (PG) and 36 healthy adult women (CG) of similar age. The Free List and Ranking of Foods was used to group foods and verify consensus and cultural aspects. Calories, health, and taste were the dimensions used by the participants to group the foods, and strong consensus was achieved in regard to calories and health. There were, however, inter- and intra-group divergences in regard to these ideas, especially in the PG. The CG used distinct criteria, showing a more complex model.

Best nutrition counseling practices for the treatment of anorexia nervosa: a Delphi study

OBJECTIVE

To use Delphi methodology to evaluate the extent to which a panel of registered dietitians (RDs) who treat anorexia nervosa (AN) concur on parameters related to nutrition counseling for AN.

METHOD

The twenty-one panelists who participated in this study: (i) were RDs (ii) had specialized in nutritional counseling for eating disorders for 5 years or more, and (iii) had Internet access at home or work. Over a 10-week period (between 8/2013 and 11/2013), panelists completed three iterative questionnaires. Questionnaire 1 included 12 open-ended questions regarding nutrition counseling for patients with AN. Subsequent questionnaires were developed based on a content analysis of responses to the first questionnaire, and panelists were asked to rank their level of agreement with these items.

RESULTS

Consensus was defined as 85% agreement and was achieved for 47 (35.3%) of the 133 items included in the third questionnaire. Items achieving consensus described nutrition counseling approaches that are applicable to all patients with AN, and their wording typically allowed for consideration of individual needs. Some items that did not achieve consensus reflected approaches for which individual tailoring may be necessary depending on age, stage of illness, and other patient factors. Consensus was also not shown for approaches for which there is little evidence.

DISCUSSION

Nutritional counseling intervention for AN has some consensus features, but the need for individualization was apparent. A stronger evidence-base for nutritional counseling interventions for AN would provide guidance and facilitate greater consistency among RDs regarding how to best care for this patient population.

Nutrition therapy during initiation of refeeding in underweight children and adolescent inpatients with anorexia nervosa: a systematic review of the evidence

Restoration of weight and nutritional rehabilitation are recognized as fundamental steps in the therapeutic treatment of children and adolescent inpatients with anorexia nervosa (AN). However, current recommendations on initial energy requirements for this population are inconsistent, with a clear lack of empirical evidence. Thus, the aim of our study was to systematically review, assess, and summarize the available evidence on the effect of differing nutrition therapies prescribed during refeeding on weight restoration in hospitalized children and adolescents (aged 19 years and younger) with diagnosed AN. Searches were conducted in Scopus, Web of Science, Global Health (CABI), PubMed, and the Cochrane database for articles published in English up to May 2012, and complemented by a search of the reference lists of key publications. Seven observational studies investigating a total of 403 inpatients satisfied the inclusion criteria. The range of prescribed energy intakes varied from 1,000 kcal to >1,900 kcal/day with a progressive increase during the course of hospitalization. It appeared that additional tube feeding increased the maximum energy intake and led to greater interim or discharge weight; however, this was also associated with a higher incidence of adverse effects. Overall, the level of available evidence was poor, and therefore consensus on the most effective and safe treatment for weight restoration in inpatient children and adolescents with AN is not currently feasible. Further research on refeeding methods is crucial to establish the best practice approach to treatment of this population.

Nutritional rehabilitation in anorexia nervosa: review of the literature and implications for treatment

Restoration of weight and nutritional status are key elements in the treatment of anorexia nervosa (AN). This review aims to describe issues related to the caloric requirements needed to gain and maintain weight for short and long-term recovery for AN inpatients and outpatients.We reviewed the literature in PubMed pertaining to nutritional restoration in AN between 1960-2012. Based on this search, several themes emerged: 1. AN eating behavior; 2. Weight restoration in AN; 3. Role of exercise and metabolism in resistance to weight gain; 3. Medical consequences of weight restoration; 4. Rate of weight gain; 5. Weight maintenance; and 6. Nutrient intake.A fair amount is known about overall caloric requirements for weight restoration and maintenance for AN. For example, starting at 30-40 kilocalories per kilogram per day (kcal/kg/day) with increases up to 70-100 kcal/kg/day can achieve a weight gain of 1-1.5 kg/week for inpatients. However, little is known about the effects of nutritional deficits on weight gain, or how to meet nutrient requirements for restoration of nutritional status.This review seeks to draw attention to the need for the development of a foundation of basic nutritional knowledge about AN so that future treatment can be evidenced-based.
