ABSTRACT
OBJECTIVE: To measure the prevalence of Eating Behavior Disorders (EBD) in Spanish early-adolescent students using standardized methods. METHODS: A two-stage survey of prevalence of ED in a representative sample of 12 to 13 year old students in 2007 in Zaragoza (Spain). Standard evaluation: We used a two-phase cross sectional design, which involved the screening with questionnaires (EAT at a cutoff score of 20) and subsequent semi-structured interviews (SCAN) of screen-positive and screen-negative subjects. We calculated the sociodemographic characteristics, ED prevalence with their 95% confidence intervals (CI) with Confidence Interval Analysis (C.I.A.) disk version 2.0.0 (Altman et al, 2000). The study is financed by F.I.S. PI 05/2533 (Spain Health Department). RESULTS: In 2007 we studied 701 students seventh-grade, ages 12 to 13, girls and boys, in 9 public and private schools in Zaragoza (30 classrooms). In the second phase 164 preteens agreed to proceed with the clinical evaluation (63 at risk, high scorers; 101 selected sample not at risk). ED prevalence was 0.7% EDNOS F 50.9 (CI 95%: 0.3%-1.7%). CONCLUSION: The ICD-10 point prevalence rates of ED population in Spanish preteen students is similar to those reported for other developed countries. The prevalence of subclinical ED is substantially higher than that of full-syndrome.

Estudio de corte en dos estadios de prevalenciaen una muestra representativa de estudiantes españolesde 12 a 13 años en 2007 en colegios de Zaragoza.Evaluación estándar: diseño de corte en dos estadios concribado con cuestionarios autocumplimentados (EAT-26 conpunto de corte de 20) y entrevista individual semiestructurada(SCAN) de sujetos con criba positiva y negativa. Se calculanlas características sociodemográfi cas, prevalencia de TCAcon sus intervalos de confi anza 95% (CI) con Confi dence IntervalAnalysis (C.I.A.) disk version 2.0.0 (Altman et al, 2000).El estudio se fi nancia con fondos F.I.S. PI 05/2533.Resultados. En 2007 se estudia 701 alumnos de 1º deEnseñanza Secundaria Obligatoria, de 12 y 13 años, chicos ychicas, en 9 centros de secundaria públicos y privados concertados(30 aulas) en Zaragoza (Spain). En la segunda fase164 adolescentes aceptan proceder a la evaluación clínica(163 con riesgo, altas puntuaciones en EAT-26; 101 seleccionadosde la muestra sin riesgo). La prevalencia puntualde TCA es el 0,7% de Trastornos Conducta Alimentaria noespecifi cados (TCANE) F 50.9 (CI 95%: 0,3%-1,7%).Conclusiones. Las tasas de prevalencia puntual de TCACIE-10 en la población zaragozana de estudiantes adolescentestempranos es similar a la publicada en otros paísesdesarrollados. La prevalencia de TCA subclínicos o atípicosque no cumplen todos los criterios diagnósticos es sustancialmentemayor que los síndromes completos(AU)
