- Who are the children and adolescent patients of a national referral service of eating disorders in Brazil?: a cross-sectional study of a clinical sample(2013) PINZON, Vanessa Dentzien; TURKIEWICZ, Gizela; MONTEIRO, Denise Oliveira; KORITAR, Priscila; FLEITLICH-BILYK, BacyObjectives: To investigate the sociodemographic and clinical profile of patients receiving treatment at a specialized service for children and adolescents with eating disorders (ED) in São Paulo, Brazil, and to compare data with the relevant literature. Methods: This cross-sectional study assessed male and female patients with ED up to 18 years of age. All data were collected upon admission. Results: A total of 100 subjects were assessed. Mean age was 15.41±0.18 years, and mean age at ED onset was 13.5±0.19 years. Mean disease duration was 21.06 ±1.67 months. Of the total sample, 82% of the patients were female, 84% were Caucasian, 64% came from A and B economic tiers. Moreover, in 60% ED started at 14 years of age or less, and 74% had psychiatric comorbidities. Anorexia nervosa was the most prevalent diagnosis (43%). Hospitalized patients had lower body mass index, longer ED duration, and more severe scores on the Children's Global Assessment Scale than outpatients (p < 0.05). Conclusions: Our young Brazilian patients with ED present epidemiological and symptomatic characteristics very similar to those found in the scientific literature, including a high prevalence of psychiatric comorbidities. The higher frequency of full syndrome ED, the predominance of cases with an early onset, the delay in beginning specialized treatment, and the more severe state of inpatients provide grounds for concern because these factors differ from what has been reported in reference studies and indicate greater ED severity.

Aim: To verify whether leptin, insulin-like growth factor 1 (IGF-1) or another hormonal marker could be a good predictor of the return of menses. Patients and Methods: This prospective study included female adolescents diagnosed with AN or eating disorders not otherwise specified (EDNOS) and who were being treated in an ambulatory care unit during nutritional recovery. Body mass index and leptin, luteinizing hormone, estradiol and IGF-1 levels of these patients were evaluated. Blood samples were collected in the 1st (T1), 5th (T2), 10th (T3), 15th (T4) and 20th (T5) weeks of treatment. The hormone levels during nutritional recovery and at the time of the resumption of menses were analyzed. Results: The hormonal profiles improved after nutritional recovery, with IGF-1 correlating the most with the resumption of menses and nutritional recovery (p = 0.0001). At the resumption of menstruation, the patients showed IGF-1 levels >342.8 ng/ml. Conclusion: IGF-1 was the best predictor of the return of menses in female adolescents with AN or EDNOS. (C) 2014 S.

- Validation of the Disordered Eating Attitude Scale for adolescents(2016) ALVARENGA, Marle S.; KORITAR, Priscila; PINZON, Vanessa D.; FIGUEIREDO, Manoela; FLEITLICH-BILYK, Bacy; PHILIPPI, Sonia T.; SCAGLIUSI, Fernanda B.ABSTRACT Objective To perform the psychometric evaluation of the Disordered Eating Attitude Scale (DEAS) for adolescents. Methods Sample consisted of 1,119 Brazilian adolescents (12-18 years old; 59.6% female) studying at technical schools in São Paulo state-Brazil, who answered an online survey with the DEAS, the Eating Attitude Test (EAT-26), and the Restraint Scale (RS). The internal consistency of the DEAS was assessed using Cronbach’s alpha. The convergent validity of DEAS was evaluated by means of Pearson’s coefficient correlation with EAT-26 and RS. The test-retest reliability was evaluated using a sub-sample of 61 adolescents. Known-groups validity was determined by comparing female student mean scores with scores of 33 female adolescents with eating disorders. Results The reliability of the DEAS was 0.79. EAT-26 and RS scores were positively correlated with DEAS scores (EAT: 0.78 for females and 0.59 for males, p < 0.001; RS: 0.63 for females and 0.48 for males, p < 0.001). The DEAS total and subscale scores differentiated students and patients with eating disorders (p < 0.001). The intra-class correlation coefficient for test-retest reliability was 0.87. Conclusion Results indicate that the DEAS adolescent version showed good internal consistency, convergent validity, known-groups validity, and test-retest reliability, suggesting its potential in identifying disordered eating attitudes among adolescents. It could also be helpful in identifying adolescents at risk from eating disorders, assisting in prevention programs.
- Evidence-based psychotherapy for treatment of anorexia nervosa in children and adolescents: systematic review(2018) ALCKMIN-CARVALHO, Felipe; VEGA, Juliana Bergamo; COBELO, Alicia Weisz; FABBRI, Alessandra Donzelli; PINZON, Vanessa Dentzien; MELO, Marcia Helena da SilvaBackground: Efficacy studies on the treatment of anorexia nervosa (AN) in childhood and adolescence are scarce and systematic reviews are almost non-existent. Objective: Systematic review of the literature regarding the modalities of psychological intervention based on evidence used in the treatment of AN in childhood and adolescence. Methods: The research was carried out in the databases: PubMed, PsycINFO and Cochrane, using the combined keywords: anorexia nervosa and evidence-based therapy. Articles published between 1990 and 2015 were assessed. Results: Of the 139 eligible articles, 14 were selected, of which 10 (71.4%) were conducted in the United States and England. The sample ranged from 9 to 167 participants. Randomized Clinical Trial represented the most frequent design (n = 9; 63.4%), with more than half of the interventions structured in 20 or more sessions (n = 9, 64.3%). Nine types of treatments were tested, with the most tested being Family-Based Treatment (FBT) (n = 7; 50%). Interventions involving the family seem to be more effective, however, the rates for complete remission are modest. Discussion: Although evidence of efficacy was verified in the treatments analyzed, the limited number of studies, the various methodological limitations and the methodological heterogeneity between studies make the findings inconclusive.
article 1 Citação(ões) na Scopus Anorexia nervosa: differences and similarities between adolescents with and without a history of obesity(2014) KORITAR, Priscila; PINZON, Vanessa Dentzien; BARROS, Claudia; COBELO, Alícia; FLEITLICH-BILYK, BacyThe aim of this study was to evaluate clinical differences and similarities between anorexia nervosa (AN) patients with and without a history of obesity. We evaluated 108 patients (10-18 years old) with the restricting or purging subtype of AN, treated at a public referral facility in Brazil. To evaluate clinical characteristics, we used a standardized psychiatric interview, the Development and Well-Being Assessment, the Children's Global Assessment Scale, the Eating Disorder Examination Questionnaire (EDE-Q), and body mass index (BMI)-for-age percentile. The mean age was 14.8±2.5 years, and 95 (88.0%) of the patients were female. Of the 108 patients evaluated, 78 (72.2%) had restrictive AN and 23 (21.3%) had a history of obesity. Patients with and without a history of obesity were similar in terms of age at onset, time from symptom onset to treatment, duration of treatment, impact of the disease on global functioning, and comorbidities. At treatment initiation, those with a history of obesity were at a higher BMI-for-age percentile and scored higher on the Weight Concern subscale of the EDE-Q. We conclude that severe cases of AN can occur in patients with and without a history of obesity with no differences in terms of the baseline characteristics and the duration of treatment. The significantly higher BMI-for-age percentiles amongst patients with a history of obesity (at treatment initiation) suggests that the urge for treatment shouldn't be based on BMI percentile only.- Psychopathology and adaptive functioning of parents of adolescents with anorexia nervosa(2019) ALCKMIN-CARVALHO, Felipe; VEGA, Juliana Bergamo; COBELO, Alicia Weisz; PINZON, Vanessa Dentzien
