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.

This cross-sectional study assessed male and female patients with ED up to 18 years of age. All data were collected upon admission. 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). 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.

Data were from the Welfare and Self-Sufficiency Survey conducted in a metropolitan county of Kentucky. Direct effects indicate that economic hardships and adverse life events increase depression scores and depression reduces earnings and increases welfare use. Indirect effects of economic hardships and adverse life events, through the mediating effects of depression, reinforce depression’s effects on employment and welfare use. The data include measures of life circumstances and depression scores of low-income women; thereby, permitting a path model that uniquely contributes to knowledge regarding the effects of life circumstances and depression on TANF-eligible women’s employment and welfare use.

The objective is to present the Brazilian field trial of the WHOQOL-bref. WHOQOL-bref is composed by 26 questions divided in four domains: physical, psychological, social relationships and environment. The evaliation instrument, BDI (beck depression inventory) and BHS (beck hopelessness scale) were used in a 300 subjects sample in Porto Alegre, South Brazil. The instrument showed a good performance concerning internal consistency, discriminant validity, criterion validity, concurrent validity and test-retest reliability. The intrument allies good psychometric performance and practicity for use which puts it as an interesting option to evaluate quality of life in Brazil.

Although family-based treatment has been studied in English-speaking countries, there is a need to examine the generalizability of this approach to non-English speaking cultures. This pilot-study aimed to examine the feasibility, acceptability, and effectiveness of family-based treatment in Brazil. METHOD: Observational study of adolescents with anorexia nervosa (excluding menstrual criteria), as determined with the Diagnostic and Well-Being Assessment, referred for treatment at a specialized center in São Paulo, Brazil. The following data were collected at baseline, at the end of treatment, and after six months of follow-up: weight; height; body mass index; menstrual status; Eating Disorder Examination Questionnaire score; and Children Global Assessment of Functioning Scale score. RESULTS: Of 11 eligible patients/families, 9 (82%) enrolled in the study, and 7 (78%) completed the treatment. The mean patient age was 14.64 ± 1.63 years (range, 12.33-17.00 years). The Wilcoxon signed rank test showed statistically significant improvement in weight and body mass index at the end of treatment, as well as after six months of follow-up, at which point none of the patients met the diagnostic criteria for any eating disorder. CONCLUSION: The results suggest that family-based treatment is acceptable and feasible for Brazilian families. Outcomes suggest that the approach is effective in this cultural context, leading to improvements similar to those reported in previous studies conducted in other cultures.

It is a package of questionnaires, interviews and evaluation techniques, designed to generate DSM-IV and ICD-10 based diagnoses of anorexia, bulimia nervosa and the respective partial syndromes in epidemiological studies, in subjects who are 7 to 17 years old. The parents are interviewed in all cases, as are young people aged 11 or more. METHODS: 174 girls, divided into three groups, were assessed with the Eating Disorders Section of the Development and Well-Being Assessment: 48 with eating disorders, 55 clinical controls (with depression, obsessive-compulsive disorder or gastrointestinal disease) and 71 community controls. The sensitivity, specificity and predictive values of the assessment were investigated by comparing the Development and Well-Being Assessment diagnoses with independent psychiatric diagnoses. The test-retest reliability was investigated by reapplying the measure on 55 subjects after 2 or 3 weeks. RESULTS: For the detection of any DSM-IV and ICD-10 eating disorder, the final Development and Well-Being Assessment diagnosis had a sensitivity of 100%, specificity of 94%, positive predictive value of 88%, and a negative predictive value of 100%; there was 95% agreement between the initial and repeat diagnoses (a kappa of 0.81). CONCLUSION: The Eating Disorders Section of the Development and Well-Being Assessment has suitable psychometric properties for use in clinical and epidemiological studies.
