Evidence-based psychotherapy for treatment of anorexia nervosa in children and adolescents: systematic review

Abstract Background: 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.

Age and gender changes in children and adolescent patients of a Brazilian eating disorder program

ABSTRACT Background International studies have demonstrated an increase in the prevalence of boys and a decrease of patients’ age at the beginning of outpatient treatment for eating disorders (ED). Objective To evaluate if these changes are also present in the Brazilian population participating in the PROTAD, a Brazilian ED program, and to discuss its clinical implication for treatment. Methods Cross-sectional study. We evaluated 150 medical records of patients under 18 years diagnosed with ED (DSM IV-TR). Patients were divided into two groups: G1 (2001-2007) (n = 77) and G2 (2008-2014) (n = 73). The girl/boy proportion and the mean age of patients were compared. Results In G1, six boys (7.8%) were admitted (girl/boy proportion: 11.8:1), while in G2, 16 (22%) boys were admitted (girl/boy proportion: 3.5:1) (p < 0.05). The mean age in G1 was 15.6 years (SD = 1.7; 95%CI: 15.2-15.9), whereas the mean age in G2 was 14.9 years (SD = 1.9; 95%CI: 14.4-15.3) (p > 0.05). Discussion The increase in the number of boys treated for EDs reported in international studies was also found at the PROTAD. Contrary to what has been reported in international studies, the mean age of patients at the PROTAD did not decrease significantly. Gender and sexual orientation issues, clinical presentation, prior overweight history and culture/media impact on boys should be addressed by the healthcare team to increase the therapeutic efficacy.

Anorexia nervosa: differences and similarities between adolescents with and without a history of obesity / Anorexia nerviosa: diferencias y similitudes entre adolescentes con y sin antecedentes de obesidad

The 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.

El objetivo de este estudio fue identificar las diferencias clínicas entre pacientes con anorexia nerviosa (AN) con y sin antecedentes de obesidad. Se evaluaron 108 pacientes (10-18 años de edad) con AN del subtipo restrictivo o purgativo, tratados en un centro público de referencia en Brasil. Para evaluar las características clínicas, se utilizaron una entrevista estandarizada psiquiátrica, el Development and Well-Being Assessment, la Children's Global Assessment Scale, el Eating Disorder Examination Questionnaire (EDE-Q), y el percentil del índice de masa corporal (IMC) para la edad. La edad media fue de 14.80±2, años, y 95 (88.00%) de los pacientes eran del sexo femenino. De los 108 pacientes, 78 (72.20%) tenían AN restrictiva y 23 (21.30%) tenían antecedentes de obesidad. Los pacientes con y sin antecedentes de obesidad eran similares en términos de edad de inicio de la enfermedad, tiempo desde el inicio de los síntomas hasta el inicio del tratamiento, duración del tratamiento, impacto de la enfermedad en el funcionamiento general y comorbilidades. Al inicio del tratamiento, los pacientes con antecedentes de obesidad estaban en un percentil más alto de IMC para la edad y puntuaron más alto en la subescala preocupación por el peso del EDE-Q. En conclusión, casos graves de AN pueden ocurrir en pacientes con y sin antecedentes de obesidad.

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.

OBJECTIVES: 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.

Objetivos: Investigar o perfil sociodemográfico e clínico de pacientes de um serviço especializado no tratamento de crianças e adolescentes com transtornos alimentares (TA) em São Paulo, Brasil, e comparar os dados com a literatura científica relevante. Métodos: Este estudo transversal avaliou pacientes com diagnóstico de TA de ambos os sexos, com idade até 18 anos. Os dados foram coletados na admissão dos pacientes ao serviço. Resultados: A amostra foi composta por 100 sujeitos. A idade média foi de 15,41±0,18 anos, e a média de idade ao início dos TA foi de 13,5±0,19 anos. O tempo médio de duração da doença foi de 21,06±1,67 meses. Da amostra total, 82% dos pacientes eram meninas, 84% eram brancos, 64% provinham das classes econômicas A e B. Além disso, 60% iniciaram a patologia com 14 anos ou menos e 74% tinham comorbidades psiquiátricas. A forma total da anorexia nervosa foi o diagnóstico mais prevalente (43%). Os pacientes hospitalizados tiveram menor índice de massa corporal, mais tempo de TA e escores mais graves na Escala de Avaliação Global de Crianças quando comparados com pacientes do ambulatório (p < 0,05). Conclusões: Os pacientes brasileiros jovens com TA avaliados no presente estudo apresentaram características epidemiológicas e sintomatológicas muito semelhantes aos dados da literatura científica, inclusive com relação à alta prevalência de comorbidades psiquiátricas. A maior frequência das síndromes totais dos TA, o predomínio de quadros de início precoce, o longo tempo decorrido até iniciar tratamento especializado e a maior gravidade dos pacientes hospitalizados observados nesta amostra chamam atenção por diferirem do que tem sido relatado em estudos semelhantes e também por indicarem uma maior gravidade do TA.
