The Role of Nutritional Counselling in the Treatment of Anorexia Nervosa and Bulimia Nervosa Abstract. Eating disorders such as Anorexia nervosa and Bulimia nervosa should be treated with an interdisciplinary approach. In addition to medical and psychiatric/psychotherapeutic guidance, nutritional counselling is an important part of the treatment. The focus lies on the following nutrition topics, such as: incorrect nutritional knowledge, hunger and satiety, prohibitions and bad conscience. The relationship between the affected person and the dietician plays a large role in the treatment success.

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.

Consenso sobre la evaluación y el tratamiento nutricional de los trastornos de la conducta alimentaria: bulimia nerviosa, trastorno por atracón y otros / No disponible

La bulimia nerviosa y el trastorno por atracón constituyen entidades nosológicas propias. Ambas muestran una gran variabilidad en su presentación y gravedad, lo que implica la individualización del tratamiento y la necesidad de equipos multidisciplinares. Los pacientes con bulimia nerviosa pueden presentar desde desnutrición y estados carenciales a exceso de peso, mientras que en los trastornos por atracón es habitual el sobrepeso u obesidad, que condiciona a su vez otras comorbilidades. Muchos de los síntomas y complicaciones derivan de las conductas compensatorias. Se dispone de diversas herramientas terapéuticas para el tratamiento de estos pacientes. El abordaje nutricional contempla el consejo dietético individualizado que garantice un adecuado estado nutricional y la correcta educación nutricional. Su objetivo es facilitar la adopción voluntaria de comportamientos alimentarios que fomenten la salud y que permitan la modificación a largo plazo de los hábitos alimentarios y el cese de conductas purgantes y atracones. El soporte psicológico es el tratamiento de primera línea y debe abordar el trastorno de la conducta alimentaria y las comorbilidades psiquiátricas que frecuentemente presentan. Los psicofármacos, aunque eficaces y ampliamente utilizados, no son imprescindibles. El manejo se realiza principalmente a nivel ambulatorio, siendo el hospital de día útil en pacientes seleccionados. Se debe reservar la hospitalización para corregir aquellas complicaciones somáticas o psiquiátricas graves o como medida de contención de las situaciones conflictivas no tratables de forma ambulatoria. La mayoría de las recomendaciones de las guías se basan en consensos de expertos, existiendo poca evidencia que evalúe los resultados clínicos y de coste-eficacia

Bulimia nervosa and binge eating disorder are unique nosological entities. Both show a large variability related to its presentation and severity which involves different therapeutic approaches and the need to individualize the treatment, thus it is indispensable a multidisciplinary approach. Patients with bulimia nervosa may suffer from malnutrition and deficiency states or even excess weight, while in binge eating disorders, it is common overweight or obesity, which determine other comorbidities. Many of the symptoms and complications are associated with compensatory behaviors. There are many therapeutic tools available for the treatment of these patients. The nutritional approach contemplates the individualized dietary advice which guarantees an adequate nutritional state and nutritional education. Its objective is to facilitate the voluntary adoption of eating behaviors that promote health and allow the long-term modification of eating habits and the cessation of purgatory and bingeing behaviors. Psychological support is a first-line treatment and it must address the frequent disorder of eating behavior and psychiatric comorbidities. Psychotropic drugs are effective and widely used although these drugs are not essential. The management is carried out mainly at an outpatient level, being the day hospital useful in selected patients. Hospitalization should be reserved to correct serious somatic or psychiatric complications or as a measure to contain non-treatable conflict situations. Most of the guidelines' recommendations are based on expert consensus, with little evidence which evaluates clinical results and cost-effectiveness

Eating disorders during the adolescence: personality characteristics associated with anorexia and bulimia nervosa / Trastornos de la conducta alimentaria durante la adolescencia: perfiles de personalidad asociados a la anorexia y a la bulimia nerviosa

Introduction: Previous studies provide relevant information about the relationship between personality and eating disorders (ED). The involvement of personality factors in the etiology and maintenance of ED indicates the need of emphasizing the study of the adolescent's personality when diagnosed of ED. Objectives: The aims of this study were to analyze the adolescent's personality profiles that differ significantly in anorexia nervosa (AN) and bulimia nervosa (BN), and to explore the most common profiles and their associations with those subtypes of eating disorders (ED). Methods: A total of 104 patients with AN and BN were studied by means of the Millon Adolescent Clinical Inventory (MACI). Results: The personality profiles that differ significantly in both AN and BN were submissive, egotistic, unruly, forceful, conforming, oppositional, self-demeaning and borderline. The most frequent profiles in AN were conforming (33.33%), egotistic (22.72%) and dramatizing (18.18%) while in the case of BN those profiles were unruly (18.42%), submissive (18.42%) and borderline (15.78%). We did not find any associations between the diagnostic subgroup (AN, BN) and the fact of having personality profiles that could become dysfunctional. Conclusions: Bearing in mind these results, it may be concluded that there are relevant differences between personality profiles associated with AN and BN during adolescence, so tailoring therapeutic interventions for this specific population would be important (AU)

Introducción: estudios previos aportan información relevante sobre la relación entre la personalidad y los trastornos de conducta alimentaria (TCA). La implicación de los factores de personalidad en la etiología y el mantenimiento de los TCA indica la necesidad de enfatizar el estudio de la personalidad del adolescente cuando se diagnostique un TCA. Objetivos: los objetivos del presente estudio fueron explorar los perfiles de personalidad más frecuentes asociados a la anorexia nerviosa (AN) y a la bulimia nerviosa (BN) en adolescentes y analizar aquellos perfiles de personalidad que diferencian de manera significativa a ambos subtipos de TCA. Métodos: un total de 104 pacientes con diagnóstico de AN y BN fueron estudiados mediante el Inventario Clínico para Adolescentes de Millon (MACI). Resultados: los perfiles de personalidad que difieren significativamente entre AN y BN fueron los perfiles sumiso, egocéntrico, rebelde, rudo, conformista, oposicionista, autopunitivo y tendencia límite. Los perfiles de personalidad más frecuentes en la AN fueron el conformista (33,33%), el egocéntrico (22,72%) y el histriónico (18,18%), mientras que en la BN los más prevalentes fueron el rebelde (18,42%), el sumiso (18,42%) y el límite (15,78%). No encontramos ninguna asociación entre el subgrupo diagnóstico (AN, BN) y el hecho de tener perfiles de personalidad que podrían llegar a ser disfuncionales. Conclusiones: existen diferencias relevantes entre los perfiles de personalidad asociados a la AN y la BN durante la adolescencia, por lo que sería importante adaptar las intervenciones terapéuticas para esta población específica (AU)

Anorexia y bulimia nerviosas: difusión virtual de la enfermedad como estilo de vida / Anorexia and bulimia nervosa: virtual diffusion of the disease as a lifestyle

Introducción: la adolescencia es un periodo vulnerable para padecer trastornos de la conducta alimentaria (TCA) como la anorexia y la bulimia nerviosas. La insatisfacción corporal, uno de los factores precipitantes de los TCA, conduce a las adolescentes a la búsqueda de información sobre dietas en internet. En este contexto, las páginas pro-Ana (proanorexia) y pro-Mía (probulimia) difunden contenidos altamente perjudiciales para la salud relacionados con la pérdida de peso y los TCA. Objetivos: en el presente trabajo se analizan la cantidad, el posicionamiento, la calidad y la difusión de las páginas pro-Ana y pro-Mía. Métodos: se realizó una búsqueda de páginas web en el navegador Google Chrome con las palabras clave «anorexia», «bulimia», «trastornos de la conducta alimentaria (TCA)», «Ana y Mía», «pro-Ana y pro-Mía», «anorexic nation», «obesidad», «estilos de vida saludables» y «nutrición saludable». Se seleccionaron los 20 primeros resultados de cada búsqueda según los índices de posicionamiento de PageRank y se analizó la calidad de dichos recursos mediante un cuestionario. Para el estudio de la difusión de páginas pro-Ana y pro-Mía en redes sociales como Facebook y Twitter se utilizó el programa SharedCount. Resultados: pro-Ana y pro-Mía dieron más de un millón de entradas, siendo páginas mal posicionadas, de tipo blog en su mayoría, con mayor difusión en Facebook y Twitter comparadas con otras de mejor calidad. Conclusiones: pro-Ana y pro-Mía son recursos con una clara intencionalidad de contactar con personas que padecen un TCA o están en riesgo, con el fin de reforzar la comunicación entre ellas a través de la blogosfera (AU)

Introduction: Adolescence is a vulnerable period for the onset of eating disorders (ED) such as anorexia and bulimia nervosas. Body dissatisfaction, a precipitating factor for ED, leads adolescents to seek information on the Internet about diets. In this context, pro-Ana (proanorexia) and pro-Mia (probulimia) are on-line pages that promulgate highly harmful contents for health related to weight loss and ED. Objectives: The aim of this study was to analyze quantity, quality and social diffusion strategies used by pro-Ana and pro-Mia webpages. Methods: A web search was done in the Google Chrome browser, using the keywords «anorexia», «bulimia», «eating disorders», «Ana and Mia», «pro-Ana and pro-Mia», «anorexic nation», «obesity», «healthy lifestyles» and «healthy nutrition». The top 20 results for each search were selected and analyzed according to positioning rates (PageRank, PR). The quality of these resources was analyzed by a previously published questionnaire. Finally, a study of the diffusion in social networks like Facebook and Twitter was performed for pro-Ana and pro-Mia pages using SharedCount. Results: Searches for pro-Ana and pro-Mia reported more than a million entries. The pages were poorly positioned. Blog contents were the most shared between all the analyzed pages. Conclusions: pro-Ana and pro-Mia are resources with a clear intention to establish a contact with people with an eating disorder or who are at risk for developing one, in order to strengthen the communication through the blogosphere (AU)

Suplementos nutricionales en trastornos de la conducta alimentaria / Nutritional supplements in eating disorders

Se consideran Trastornos de la Conducta Alimentaria (TCA) a una serie de entidades nosológicas diferenciadas que tienen como nexo común una alteración continuada en la ingesta o bien en la conducta relacionada con la ingesta. Dentro de dicha clasificación destacan los siguientes trastornos: Anorexia Nerviosa (AN) y Bulimia Nerviosa (BN). La AN es un trastorno de curso crónico caracterizado principalmente por una negativa o disminución de la ingesta acompañado de una distorsión de la imagen corporal con el consecuente miedo intenso a la ganancia de peso. Se estima una prevalencia vital en la adolescencia de dicho trastorno de aproximadamente el 0,5-1%1. En la BN la presencia de atracones de comida y la posterior conducta compensatoria (en forma de ejercicio intenso, uso de laxantes, diuréticos...) es lo que prima en el paciente. La prevalencia se estima entre un 2 y un 4% en mujeres jóvenes, iniciándose generalmente en etapas algo posteriores que la AN. Se cree que en su patogenia influyen factores biológicos, psicológicos y ambientales así como una cierta vulnerabilidad genética. Existen distintos tratamientos con eficacia avalada por parte de literatura científica, tanto terapias biológicas como psicológicas, a pesar de ello, nos encontramos con una efectividad parcial de dichas terapias siendo necesaria la búsqueda de nuevas dianas así como de nuevos tratamiento. Aunque la etiopatogenia de los TCA no esté clara, algunas de las disfunciones neurobiológicas encontradas permitirían considerar que la dieta y la administración de nutrientes podría ser relevante en el tratamiento de estos trastornos. Proponemos en este artículo una revisión de nuevos tratamientos enfocados al déficit nutricional (AU)

Eating disorders (EDs) are a series of differentiated nosological entities sharing the common link of a continuous alteration in food intake or in food intake-related behavior. Within this classification, the following disorders are noteworthy: anorexia nerviosa (AN) and bulimia nerviosa (BN). Anorexia nervosa is a chronic disorder characterized mainly by negative or decreased food intake accompanied by a distortion of body image and intense accompanying fear of weight gain. The estimated vital prevalence of this disorder in adolescence is approximately 0.5%-1%.1 The primary feature of BN is the presence of binge eating accompanied by compensatory behavior (in the form of intense exercise and the use of laxatives and diuretics, etc.). The prevalence of BN is estimated to be between 2% and 4% in young women, and it generally starts at somewhat later stages than AN. It is believed that biological, psychological, and environmental factors, as well as genetic vulnerability, influence the pathogenesis of EDs. A variety of therapies exist, both biological and psychological, whose effectiveness is supported by the scientific literature. Nonetheless, we find these therapies only partially effective and new targets as well as new treatments should be sought. Although the etiopathogenesis of EDs is unclear, some of the neurobiological dysfunction found suggests that diet and nutrient supplementation could be relevant in their treatment. We review in this article new treatments focusing on nutritional déficits (AU)

"Las penas con pan duelen menos": The role of food and culture in Latinas with disordered eating behaviors.

This study elucidated the experiences of eighteen Latina adults (mean age = 38.5 years) from "Promoviendo una Alimentación Saludable" Project who received nutritional intervention as part of the clinical trial. Half of the participants were first generation immigrants from Mexico (50%), followed by U.S. born with 16.7%. Remaining nationalities represented were Bolivia, Colombia, Guatemala, Honduras, Peru, and Venezuela with 33.3% combined. The average duration of living in the U.S. was 11.1 years. The mean body mass index (BMI) at baseline was 36.59 kg/m(2) (SD = 7.72). Based on the DSM-IV, 28% (n = 5) participants were diagnosed with binge-eating disorder, 33% (n = 6) with bulimia nervosa purging type and 39% (n = 7) with eating disorder not otherwise specified. Participants received up to three nutritional sessions; a bilingual dietitian conducted 97.8% of sessions in Spanish. In total, fifty nutritional sessions were included in the qualitative analysis. A three step qualitative analysis was conducted. First, a bilingual research team documented each topic discussed by patients and all interventions conducted by the dietitian. Second, all topics were classified into specific categories and the frequency was documented. Third, a consensus with the dietitian was performed to validate the categories identified by the research team. Six categories (describing eating patterns, emotional distress, Latino culture values, family conflicts associated with disturbed eating behaviors, lack of knowledge of healthy eating, and treatment progress) emerged from patients across all nutritional sessions. Considering the background of immigration and trauma (60%, n = 15) in this sample; the appropriate steps of nutritional intervention appear to be: 1) elucidating the connection between food and emotional distress, 2) providing psychoeducation of healthy eating patterns using the plate method, and 3) developing a meal plan.

Nutritional intake and dietary patterns in pregnancy: a longitudinal study of women with lifetime eating disorders.

There is limited knowledge about dietary patterns and nutrient/food intake during pregnancy in women with lifetime eating disorders (ED). The objective of the present study was to determine patterns of food and nutrient intake in women with lifetime ED as part of an existing longitudinal population-based cohort: the Avon Longitudinal Study of Parents and Children. Women with singleton pregnancies and no lifetime psychiatric disorders other than ED (n 9723) were compared with women who reported lifetime (ever) ED: (anorexia nervosa (AN, n 151), bulimia nervosa (BN, n 186) or both (AN+BN, n 77)). Women reported usual food consumption using a FFQ at 32 weeks of gestation. Nutrient intakes, frequency of consumption of food groups and overall dietary patterns were examined. Women with lifetime ED were compared with control women using linear regression and logistic regression (as appropriate) after adjustment for relevant covariates, and for multiple comparisons. Women with lifetime ED scored higher on the 'vegetarian' dietary pattern; they had a lower intake of meat, which was compensated by a higher consumption of soya products and pulses compared with the controls. Lifetime AN increased the risk for a high ( ≥ 2500 g/week) caffeine consumption in pregnancy. No deficiencies in mineral and vitamin intake were evident across the groups, although small differences were observed in macronutrient intakes. In conclusion, despite some differences in food group consumption, women with lifetime ED had similar patterns of nutrient intake to healthy controls. Important differences in relation to meat eating and vegetarianism were highlighted, as well as high caffeine consumption. These differences might have an important impact on fetal development.

Anorexia y Bulimia Nerviosa. Aproximación nutricional / Anorexia and Bulimia Nervosa. Nutritional approach

La prevalencia entre los adolescentes, de trastornos de la conducta alimentaria como anorexia nerviosa (AN), bulimia nerviosa (BN) y otro (obesidad, alimentación compulsiva, o no especificados), viene creciendo día a día de modo sostenido y a gran velocidad; y siendo la alimentación una necesidad básica, importante y vital para el crecimiento y desarrollo, debe entenderse que este acto ejerce una conducta poderosa influencia en la estructura y funcionamiento del organismo por lo tanto una conducta alimentaria adecuada hace posible que esto se desarrolle de manera adecuada y óptima. Cada sociedad tiene formas habituales de alimentarse según sus costumbres y características socioculturales y religiosas; cuando un individuo se aparta de los límites racionales presentando características anormales tanto en la calidad como en la cantidad o distribución de las comidas a esto se le llama ôTrastornos en la Conducta Alimentariaõ. El tratamiento de los trastornos en la conducta alimentaria representa todo un desafío de Salud Pública por su alta incidencia, gravedad y evolución clínica prolongada con propensión a la cronicidad y por el grupo etáreo afectado, por lo tanto, es indispensable buscar las herramientas que permitan una detección temprana y una intervención especializada con un equipo multidisciplinario que incluya médico, psicólogo, nutricionista, psiquiatría, de modo que el pronóstico de recuperación sea el mejor posible.

The role of orexigenic and anorexigenic factors in an interdisciplinary weight loss therapy for obese adolescents with symptoms of eating disorders.

AIM: The aim of this study was to evaluate the role of orexigenic and anorexigenic factors in an interdisciplinary weight loss therapy for obese adolescents with symptoms of eating disorders. METHODS: Thirty-seven post-pubertal, obese adolescents (14 to 19 years old) with symptoms of eating disorders were submitted to long-term interdisciplinary therapy (1 year). Bulimic and binge eating symptoms were measured using the Bulimic Investigatory Test, Edinburgh, and the Binge Eating Scale respectively. Neuropeptide Y, melanin-concentrating hormone, total ghrelin, alpha-melanocyte stimulating hormone and leptin were measured using radioimmunoassay. RESULTS: After long-term interdisciplinary therapy, the adolescents showed significantly improved body composition, visceral and subcutaneous fat and reduced symptoms of bulimia and binge eating. Intriguingly, orexigenic peptides were up-regulated after short-term therapy and down-regulated at the end of therapy, whereas the anorexigenic pathway was improved with therapy. Furthermore, after long-term therapy, a negative correlation was observed between leptin concentration and melanin-concentrating hormone. DISCUSSION: We suggest that long-term therapy promotes an intrinsic association between weight loss, improvement of eating disorder symptoms and a decrease in orexigenic factors. Together, these results represent a more effective course by which patients can normalise behaviours related to eating disorders as well the actions of hormones involved in energy balance, and thus advance obesity control. CONCLUSION: Long-term interdisciplinary therapy was effective to improve anorexigenic and orexigenic factors that influence energy balance and avoid the development of eating disorders in obese adolescents. However, the associations between eating disorders and neuroendocrine factors need to be confirmed in future studies.

Micronutrient deficiencies and supplementation in anorexia and bulimia nervosa: a review of literature.

Anorexia and bulimia nervosa are characterized by unbalanced eating patterns that include inadequate dietary intake of various nutrients. Conservation mechanisms resulting from starvation and/or self-prescribed nutrient supplements can result in laboratory values that appear within normal limits. These artificially inflated values drop to dangerous levels in some patients once rehydration and refeeding begin. Electrolyte status must be closely monitored during this time to prevent complications. Other micronutrient deficiencies can be corrected with adequate dietary intake, but patients with eating disorders are unlikely to consume such an adequate diet immediately upon entering treatment, so they may benefit from supplementation. Depleted nutrient stores require longer supplementation than acute inadequacies in nutrient intake. This review compiles the findings reported to date regarding micronutrient deficiencies and supplementation for patients with anorexia and bulimia. Because of the widely varying eating practices from patient to patient and the current lack of data controlling for nutrient self-supplementation, nutrition assessment performed by a nutrition professional via food intake history may be more practical than laboratory tests and more accurate than current food intake for determining potential micronutrient deficiencies.

Adipocyte fatty acid binding protein during refeeding of female patients with anorexia nervosa.

BACKGROUND: Adipocyte fatty acid binding protein (A-FABP) has been suggested to play an important role in fat metabolism linking obesity and the metabolic syndrome. Increasing A-FABP plasma levels were observed during greatest weight loss after bariatric surgery suggesting that A-FABP may indicate changes in fat mass in dynamic situations. AIM OF THE STUDY: As there are no data on weight gain, we investigated the effect of refeeding anorexic patients on body composition and A-FABP plasma levels. METHODS: Parameters of glucose and lipid metabolism as well as plasma levels of leptin and A-FABP were prospectively assessed in 16 female patients with anorexia nervosa during inpatient weight restoration. Body composition was determined by multifrequency body impedance analysis. RESULTS: After 28 days, fat mass increased from 4.4 +/- 2.5 kg at baseline to 5.5 +/- 2.2 kg (P < 0.01), constituting 40% of total weight gain. Conversely, A-FABP concentrations decreased from 32.56 +/- 35.59 ng/ml at baseline to 21.27 +/- 13.68 ng/ml (P < 0.05), which corresponds to a significant decrease in the proportion of A-FABP per kilogram fat mass from 7.86 +/- 5.23 to 4.09 +/- 2.12 ng/ml/kg (P

When energy in does not equal energy out: disordered energy control.

OBJECTIVE: To explore women's fear of loss of control and excessive inappropriate control of eating, exercise or their body in relation to patient/nonpatient status. To examine the utility of a concept of Disordered Energy Control (DEC). METHODS: Comparison of the features of DEC of 169 female eating disorder, first admission inpatients, 61 previous inpatients ('recovering') and 225 female students who completed computer questions including the Quality of Life Eating Disorder (QOL ED). RESULTS: Fear of loss of control was reported by 89% of inpatients, 36% of 'recovering' patients and 34% of students. Fear of loss of control or excessive controlling behaviour (defined as BMI <15.5, vomiting >7 days/month) was reported by 96% of inpatients (97% anorexia nervosa, 100% bulimia nervosa, 89% EDNOS), 51% of 'recovering' patients and 35% of students. There was significantly more impact on QOL ED psychological aspects, daily living, and acute medical health for student and patient groups reporting control issues compared to those who did not. DEC was present in 13% of students, 94% of inpatients and 28% of recovering patients. DISCUSSION: The concept of disordered energy control warrants further investigation particularly in overweight and obese groups. A biological measure of inappropriate energy control associated with medical and psychological problems would be useful.

Psychometric properties of the State and Trait Food Cravings Questionnaires among overweight and obese persons.

A crucial problem in studies involving food cravings is the lack of a psychometrically sound measure for use among overweight and obese populations. The degree to which the Food Cravings Questionnaires-Trait (FCQ-T) and State (FCQ-S) evidenced acceptable psychometric properties among overweight and obese participants was assessed. In study 1, 109 participants completed the FCQ-T and FCQ-S. Item-total correlations, test-retest reliability, internal consistency, and factor structures were examined. Results indicate good internal consistency and partially support the factor structures. In study 2, the construct and predictive validity of the FCQ-S were examined. Twenty-eight women completed the FCQ-S 15 min after finishing a standardized breakfast and then twice more, 90 min apart. Subsequent ad libitum food intake was recorded. Results suggest that the FCQ-S is sensitive to state changes in food cravings, but that the magnitude of the changes was moderate. The FCQ-S was not a good predictor of subsequent food intake. The FCQ-T and FCQ-S may be useful in studies that examine triggers of and interventions for excessive food intake.

Testing mediators of intervention effects in randomized controlled trials: An evaluation of two eating disorder prevention programs.

The authors investigated mediators hypothesized to account for the effects of 2 eating disorder prevention programs using data from 355 adolescent girls who were randomized to a dissonance or a healthy weight intervention or an active control condition. The dissonance intervention produced significant reductions in outcomes (body dissatisfaction, dieting, negative affect, bulimic symptoms) and the mediator (thin-ideal internalization), change in the mediator correlated with change in outcomes and usually occurred before change in outcomes, and intervention effects became significantly weaker when change in the mediator was partialed, providing support for the hypothesized mediators and this new approach to testing mediation in randomized trials. Findings provide somewhat less support for the hypothesis that change in healthy eating and exercise would mediate the healthy weight intervention effects.

Weight suppression is a robust predictor of outcome in the cognitive-behavioral treatment of bulimia nervosa.

This study examined weight suppression (difference between highest premorbid weight and pretreatment weight) as a predictor of outcome in 188 outpatients with bulimia nervosa enrolled in a cognitive-behavioral therapy intervention. Participants who dropped out of treatment had significantly higher levels of weight suppression than treatment completers. Of participants who completed treatment, those who continued to engage in binge eating or purging had significantly higher levels of weight suppression than those who were abstinent from bingeing and purging. Results did not change when body mass index, dietary restraint, weight and shape concerns, or other relevant variables were controlled. Relinquishing bulimic behaviors and adopting normal eating patterns may be most feasible for patients who are closest to their highest premorbid weights.

Evaluation of a healthy-weight treatment program for bulimia nervosa: a preliminary randomized trial.

OBJECTIVE: Conduct a randomized treatment trial to test whether healthy dieting maintains bulimic symptoms or effectively reduces this eating disturbance. METHODS: Female participants (n=85) with full- and sub-threshold bulimia nervosa were randomly assigned to a 6-session healthy dieting intervention or waitlist condition and assessed through 3-month follow-up. RESULTS: Relative to control participants, intervention participants showed modest weight loss during treatment and demonstrated significant improvements in bulimic symptoms that persisted through follow-up. DISCUSSION: These preliminary results suggest that this intervention shows potential for the treatment of bulimia nervosa and may be worthy of future refinement and evaluation. Results also provide experimental evidence that dieting behaviors do not maintain bulimia nervosa, suggesting the need to reconsider maintenance models for this eating disorder.
