A review of Latin American studies on binge eating disorder

OBJECTIVE: To review the state of the art of the scientific literature on binge eating disorder in Latin America. METHOD: A literature search of studies conducted in Latin American countries using the term binge eating was performed in the following electronic databases: PubMed, LILACS, SciELO, and PsycINFO. Selected articles described studies developed with Latin American samples that met partial or complete DSM-IV diagnostic criteria for binge eating disorder. RESULTS: 8,123 articles were screened and 30 studies met the inclusion criteria (18 cross-sectional studies, 5 clinical trials, 4 case reports, 2 validity studies, and 1 cohort study). Most of the studies were conducted in Brazil (27), one in Argentina, one in Colombia, and one in Venezuela. The prevalence of binge eating disorder among obese people attending weight loss programs ranged between 16% and 51.6%. The comparison between obese people with and without binge eating disorder showed a tendency of higher weight, longer history of weight fluctuation, more concern about shape and weight, and association with psychiatric comorbidity in those with binge eating disorder. CONCLUSION: Binge eating disorder is a detectable phenomenon in Latin America with clinical features similar to those found in the international literature. This review provides support for the consideration of binge eating disorder as a distinct eating disorder in the International Classification of Diseases - 11th edition.OBJETIVO: Revisar o estado de arte da literatura latino-americana sobre o transtorno da compulsão alimentar periódica. MÉTODO: Foi feita uma busca sobre estudos realizados em países latino-americanos usando-se o termo binge eating, nas seguintes bases eletrônicas: PubMed, LILACS, SciELO e PsycINFO. O critério de inclusão foi selecionar estudos desenvolvidos com amostras latino-americanas que preencheram critérios parciais ou completos do transtorno da compulsão alimentar periódica pelo Manual Diagnóstico e Estatístico de Transtornos Mentais-4ª Edição. RESULTADOS: Foram rastreados 8.123 artigos e 30 preencheram o critério de inclusão (18 estudos de corte transversal, cinco ensaios clínicos, quatro relatos de casos, dois estudos de validade, um estudo de coorte). A maioria dos estudos foi conduzida no Brasil (27), um na Argentina, um na Colômbia e um na Venezuela. A prevalência de transtorno da compulsão alimentar periódica em obesos em programas para perda de peso esteve entre 16% e 51,6%. A comparação entre obesos com e sem transtorno da compulsão alimentar periódica mostrou uma maior tendência para peso mais alto, oscilação ponderal, preocupação com peso e forma corporal e associação com comorbidades psiquiátricas naqueles com transtorno da compulsão alimentar periódica. CONCLUSÃO: O transtorno da compulsão alimentar periódica mostra-se um fenômeno verificável na América Latina com características clínicas semelhantes às encontradas na literatura internacional. Esta revisão fornece subsídios para que o transtorno da compulsão alimentar periódica seja considerado uma categoria distinta de transtorno alimentar na Classificação Internacional de Doenças-11ª Edição.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Universidade Federal de São Paulo (UNIFESP)Universidade Federal de São Paulo (UNIFESP) Departamento de PsiquiatriaKing's College London Health Service and Population Research Department Instituto de PsiquiatriaUNIFESP, Depto. de PsiquiatriaSciEL

Physical and mental health outcomes of an integrated cognitive behavioural and weight management therapy for people with an eating disorder characterized by binge eating and a high body mass index : a randomized controlled trial

Background: Bulimia nervosa (BN) and binge eating disorder (BED) are eating disorders (EDs) characterized by recurrent binge eating. They are associated with medical complications, impaired adaptive function and often a high BMI, for which a multidisciplinary treatment approach may be needed. This study explored the efficacy of a novel intervention integrating Cognitive Behavioural Therapy- Enhanced (CBT-E) and weight management for people with recurrent binge eating episodes and high BMI with respect to physical, psychopathological and quality of life outcomes. Methods: Ninety-eight adults diagnosed with BN, BED, or Other Specified/Unspecified Feeding or Eating Disorder (OSFED/UFED) and BMI ≥ 27 to <40 kg/m2 were randomized to a multidisciplinary approach, the Healthy APproach to weIght management and Food in Eating Disorders (HAPIFED) or to CBT-E. Metabolic parameters, health-related quality of life, general psychological and ED symptoms and ED diagnostic status outcomes are reported. Data were analyzed with mixed effects models adopting multiple imputed datasets where data were missing. Results: Both HAPIFED and CBT-E showed statistical significance for the time effect, with reduction in stress (p < 0.001), improvement in mental health-related quality of life (p = 0.032), reduction in binge eating severity (p < 0.001), and also in global ED symptoms scores (p < 0.001), with the significant changes found at end of treatment and sustained at 12-month follow-up. However, no statistical significance was found for differences between the interventions in any of the outcomes measured. Despite a high BMI, most participants (> 75%) had blood test results for glucose, insulin, triglycerides and cholesterol within the normal range, and 52% were within the normal range for the physical component of quality of life at baseline with no change during the trial period. Conclusion: Integrating weight and ED management resulted in comparable outcomes to ED therapy alone. Although adding weight management to an ED intervention had no adverse effects on psychological outcomes, it also had no beneficial effect on metabolic outcomes. Therefore, more intense weight management strategies may be required where indicated to improve metabolic outcomes. Safety will need to be concurrently investigated.

An empirical evaluation of the translation to Brazilian Portuguese of the Loss of Control over Eating Scale (LOCES)

Background Loss of control over eating is a key feature of the most prevalent eating disorders. The Loss of Control over Eating Scale (LOCES) enables a thorough assessment of loss of control over eating. Objective This study empirically evaluated the translation of the LOCES from English to Brazilian Portuguese. Methods The scale was translated to Brazilian Portuguese and back translated to English in order to check accuracy of the translation. Two hundred and ninety-three medicine and nursing students, 60 males and 233 females, 18-55 years old, with mean body mass index (BMI) 23.2 kg/m2 (SD 4.1), recruited between August and December 2014, answered the Brazilian Portuguese LOCES. An exploratory factor analysis was performed. Results Exploratory factor analysis of the Brazilian Portuguese LOCES showed three distinct factors of the loss of control over eating (disgust/negative sensations, cognitive experiences/dissociation, and “positive” effects) as well as moderate consistency with previous reports of exploratory factor analysis of the English version. Discussion This study showed satisfactory translation of the LOCES from English to Brazilian Portuguese, which is now ready for further validation

Problematic eating behaviors and psychopathology in patients undergoing bariatric surgery: The mediating role of loss of control eating

ObjectiveThis study compares different problematic eating behaviors (PEBs; objective [OBE]/subjective [SBE] binge-eating and compulsive [CG]/noncompulsive [NCG] grazing) in relation to the severity of loss of control (LOC) and psychopathology. We also investigate LOC as a mediator between PEBs and psychopathology.MethodThis cross-sectional study assessed a group of patients before bariatric surgery (n=163), and a group of bariatric patients 12 months or more after surgery (n=131). Face-to-face assessment: Eating Disorders Examination for binge-eating episodes; Rep(eat) for grazing. LOC was measured by five questions answered in a 5-point Likert scale. Self-report measures: disordered eating, grazing, negative urgency, depression, anxiety, and stress.ResultsOBEs were reported by 26(8.8%), SBE by 29(9.8%), CG by 35(11.9%), and NCG by 36(12.2%) of patients. The different PEBs differed significantly in the severity of LOC (F(3,120)= 25.81, p<.001). Patients reporting OBEs scored higher and patients with NCG scored lower in most measures than patients with other PEBs. Patients with any PEBs scored higher in all self-report measures than those not reporting any PEBs, with statistical significance reached for uncontrolled eating (F(4,288)= 20.21, p<.001), emotional eating (F(4,288)= 23.10, p<.001), repetitive eating F(4,288)= 18.34, p<.001), and compulsive grazing (F(4,288)= 27.14, p<.001). LOC was found to be a full mediator between PEBs and psychopathology.DiscussionThere is no evidence that the different PEBs differ in the psychopathology severity, independently of the experience of LOC eating during the eating episodes. We show evidence for the conceptualization of different PEB, including grazing, on a continuous scale of LOC and psychopathology.Fundacao para a Ciencia e a Tecnologia, Grant Numbers: IF/01219/2014, SFRH/BPD/94490/2013, SFRH/BPD/94490/2013, SFRH/BD/104159/2014, SFRH/BD/104182/2014, UID/PSI/01662/2013, PTDC/MHC-PCL/4974/201
