    Research from high-income countries has shown that grazing is a common but problematic eating pattern, particularly when associated with a sense of loss of control. However, it is unclear whether these patterns hold globally. Thus, the goal of this study was to extend previous research by examining the prevalence and clinical correlates of compulsive grazing (CG) and non-compulsive grazing (NCG) in a middle-income country. Participants (N = 2297) comprised adult residents from Rio de Janeiro, Brazil. Recruitment of this population-based household survey occurred from September 2019 to February 2020. The short inventory of grazing was used to operationalise grazing subtypes. Chi-square analyses, logistic regression, and univariate tests were conducted using the complex samples procedure. The point prevalence of regular CG was 10.2% (n = 239) and was consistent with high-income countries, while NCG was 29.8% (n = 679) and was less frequent than reported in high-income countries. Additionally, similar to high-income countries, CG was associated with a higher body mass index and higher odds of eating disorders, eating disorder symptomatology, depression, anxiety, and a lower physical and mental health-related quality of life, than no grazing and NCG. Overall, this study demonstrated that grazing patterns in high-income countries extend to middle-income countries

    Grazing is associated with ADHD symptoms, substance use, and impulsivity in a representative sample of a large metropolitan area in Brazil

    Grazing is a clinically relevant eating behaviour, especially when it presents with a sense of loss of control (compulsive grazing). There is evidence that other disordered eating patterns are associated with problematic substance use and impulsivity-related conditions, such as attention-deficit/hyperactivity disorder (ADHD). This overlap contributes to higher psychopathology and treatment complications. Less is known about grazing, and most information originates in high-income countries. Hence, we sought to investigate relationships between grazing, tobacco and alcohol use, ADHD, and impulsivity in a large representative sample from Brazil. Data were collected by trained interviewers from adults (N = 2297) through an in-person household survey based on a stratified and clustered probability sample. We found significant associations between compulsive grazing and problematic alcohol use (OR = 3.02, 95% CI: 1.65, 5.53), ADHD (OR = 8.94, 95% CI: 5.11, 15.63), and smoking (OR = 1.67, 95% CI: 1.12, 2.47), with impulsivity contributing to the first two relationships. The substantial association with ADHD suggests that other executive functions may promote disordered eating, possibly expressed through difficulties in adhering to regular meals. Clinically, these findings highlight the importance of assessing problematic eating patterns, such as compulsive grazing, in those presenting with difficulties with substance use or impulsivity, and vice versa

    The current study investigated the comprehension of mindfulness-based cognitive behavioral therapy (MBCT) by patients with resistant depression at the Psychiatry Institute of the Federal University of Rio de Janeiro, Brazil. This was the first time the model was used in the institution to treat these patients. In this study, 45 patients were invited to participate in a baseline session of MBCT that consisted in the explanation of the model and experimental exercises conducted by two experienced therapists. Twenty eight patients accepted to participate. At the end of the intervention, the patients completed a self-administered questionnaire designed by our ambulatory to assess their understanding of the method’s goals. Patients with anxiety disorder was also accessed for group comparison. More than 75% of the patients rated the intervention as comprehensible and workable. Compared to patients with depression, patients with anxiety had a better understanding of the mindfulness framework (6.5%) and the meaning of cognitive behavioral therapy (17.6%). Patients that completed the intervention described the baseline session of MBCT as comprehensive and acceptable. These results may allow possible future developments in the practice of mindfulness as a treatment applicable in many condition and settings even in the Brazilian context

    The prevalence of binge eating spectrum conditions (BESC) are increasing globally. However, there is a lack of data from general population samples in low- and middle-income countries. Thus, this study described the food consumption during objective binge eating episodes (OBE) in people with BESC from a metropolitan city in Brazil. Participants comprised 136 adults (18 years old–60 years old) with Binge Eating Disorder (BED), Bulimia Nervosa (BN), or recurrent binge eating (RBE) from a two-phase epidemiological survey. They were interviewed in their homes by trained lay interviewers using the Questionnaire on Eating and Weight Patterns updated for the DSM-5 to assess BESC diagnosis and food consumption during a typical OBE. Overall, participants consumed a mean of 1067 kcal during the episodes. For the most part, these calories were derived from carbohydrates (58%) and lipids (30%), irrespective of the diagnosis. Regarding food item consumption, individuals with BED and RBE consumed staple foods (mainly rice and beans) more frequently than those with BN. Conversely, participants with BN ingested sugar-sweetened beverages more frequently than the BED group. In conclusion, there were differences in the eating patterns of individuals with BESC in Brazil. BED and RBE participants consumed more typical foods, whereas those with BN preferred foods with a high content of energy during their OBE

    Several lines of evidence suggest that Virtual Reality (VR) has a potential utility in eating disorders. The objective of this study is to review the literature on the use of VR in bulimia nervosa (BN) and binge eating disorder (BED). Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement for reporting systematic reviews, we performed a PubMed, Web of Knowledge and SCOPUS search to identify studies employing VR in the assessment and treatment of BN and BED. The following search terms were used: “virtual reality”, “eating disorders”, “binge eating”, and “bulimia nervosa”. From the 420 articles identified, 19 were selected, nine investigated VR in assessment and 10 were treatment studies (one case-report, two non-controlled and six randomized controlled trials). The studies using VR in BN and BED are at an early stage. However, considering the available evidence, the use of VR in the assessment of those conditions showed some promise in identifying: (1) how those patients experienced their body image; and (2) environments or specific kinds of foods that may trigger binge–purging cycle. Some studies using VR-based environments associated to cognitive behavioral techniques showed their potential utility in improving motivation for change, self-esteem, body image disturbances and in reducing binge eating and purging behavior

    Objective: To evaluate the efficacy and tolerability of adjunctive topiramate compared to placebo in reducing weight and binge eating in obese patients with binge-eating disorder (BED) receiving cognitive-behavior therapy (CBT).Method: A double-blind, randomized, placebo-controlled trial of 21 weeks' duration was conducted at 4 university centers. Participants were 73 obese (body mass index >= 30 kg/m(2)) outpatients with BED (DSM-IV criteria), both genders, and aged from 18 to 60 years. After a 2- to 5-week run-in period, selected participants were treated with group CBT (19 sessions) and topiramate (target daily dose, 200 mg) or placebo (September 2003-April 2005). The main outcome measure was weight change, and secondary outcome measures were binge frequencies, binge remission, Binge Eating Scale (BES) scores, and Beck Depression Inventory (BDI) scores.Results: Repeated-measures random regression analysis revealed a greater rate of weight reduction associated with topiramate over the course of treatment (p <.001), with patients taking topiramate attaining a clinically significant weight loss (-6.8 kg) compared to patients taking placebo (-0.9 kg). Although rates of reduction of binge frequencies, BES scores, and BDI scores did not differ between groups during treatment, a greater number of patients of the topiramate plus CBT group (31/37) attained binge remission compared to patients taking placebo (22/36) during the trial (p =.03). No difference between groups was found in completion rates; 1 patient (topiramate group) withdrew for adverse effect. Paresthesia and taste perversion were more frequent with topiramate, and insomnia was more frequent with placebo (p <.05).Conclusions: Topiramate added to CBT improved the efficacy of the later, increasing binge remission and weight loss in the short run. Topiramate was well tolerated, as shown by few adverse events during treatment.Clinical Trials Registration: ClinicalTrials.gov identifier NCT00307619.Univ Fed Sao Paulo, Dept Psychiat, Sao Paulo, BrazilUniv Fed Bahia, Dept Psychiat, Salvador, BA, BrazilUniv Fed Rio de Janeiro, Dept Psychiat, Rio De Janeiro, BrazilUniv Sao Paulo, Dept Psychiat, Sao Paulo, BrazilUniv Estado Rio De Janeiro, Inst Social Med, Dept Epidemiol, Rio De Janeiro, BrazilJanssen Cilag Farmaceut, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Psychiat, Sao Paulo, BrazilWeb of Scienc

    Concurrent validity of the Brazilian Portuguese version of the questionnaire on eating and weight patterns-5 (QEWP-5) in the general population

    The Questionnaire on Eating and Weight Patterns-5 is a self-report instrument developed for the screening of Binge Eating Disorder (BED) and Bulimia Nervosa (BN) according to DSM-5. The present study aimed to examine the concurrent validity of the Brazilian version of QEWP-5 to assess BED and BN in the general population. The Brazilian version of QEWP-5 was administered to 2297 subjects, aged from 18 to 60 years. All screen-positive and a subset of screen-negative participants were also interviewed by telephone using the eating disorders (ED) module of Structured Clinical Interview for DSM-IV – Patients Version (SCID-I-P) for the assessment of BED, BN, and their subthreshold forms. For the assessment of BED, the sensitivity of QEWP-5 was 0.41 and its specificity was 0.90. The positive and negative predictive values were 0.48 and 0.87, respectively. Regarding the assessment of BN, QEWP-5 showed a sensitivity of 0.56, a specificity of 0.90, a positive predictive value of 0.35, and a negative predictive value of 0.95. For the global screening of ED (BED, BN, and subthreshold forms), QEWP-5 showed a sensitivity of 0.71, a specificity of 0.83, a positive predictive value of 0.64 and a negative predictive value of 0.87. QEWP-5 can be a useful instrument for the initial screening of diagnostic threshold ED psychopathology in general population samples. However, it has less utility in identifying cases of BED and BN independently
