Resum:
OBJECTIVES: The aim of this study was to know the prevalence, to evaluate the persistence, the incidence and the risk factors of any eating disorders (ED) in a representative school population of early adolescents of both sexes in the city of Tarragona (Spain).<br/>MATERIAL AND METHOD: It is an epidemiological longitudinal study in two phases. In the first phase an initial sample of 1336 (649 boys and 687 girls, mean age: 11.37) were assessed in a two-phase design.258 subjects were selected with a screening test (ChEAT) from the initial sample and were assessed individually (141 as risk group and 117 as controls) (phase of T1), and were followed-up two years later (T2), n = 200, (113 from risk subjects and 87 from controls). <br/>Subjects were evaluated with a structured psychiatric interview according to DSM-IV criteria (Diagnostic Interview for children and adolescents DICA) to obtain diagnoses of ED using DICA-Children and DICA-Adolescents, at T1 and at T2 respectively. We also obtained data about anthropometry, eating behaviors, psychopathology, pubertal development, sociocultural influences, temperament and personality and body satisfaction.<br/>RESULTS AND CONCLUSIONS: First results are presented on the anthropometric characteristics of the adapted, Catalan version of Cheat, produced experimentally in this study (Sancho et al, 2005). 12.94% of schoolchildren in the first phase were rated equal to or above the cutoff point of the Cheat. The estimated prevalence of diagnoses of ED was 3, 44% at T1 and 3.81% at T2. Partial diagnoses (which does not meet all the criteria of severity to be considered anorexia or bulimia nervosa) -EDNOS and subclinic ED- are the most frequent diagnoses. Only there was a case of bulimia at T2.<br/>52.17% of the participants persisted with any ED at the follow-up two years later. Gender differences were significant at T2, being ED in females more prevalent, incident and persistent than boys. Participants who had the highest BMI were those who had a persistent diagnosis of some form of ED (Sancho et al. 2007). Subjects with non full-blown syndromes of eating disorders share characteristics such as temperament and character traits with subjects with full-blown syndromes. Girls showed more stability (43%) in body dissatisfaction than boys (25.8%). Overweight at preadolescence is related to body dissatisfaction in boys and girls. Dissatisfaction at preadolescence is an important predictor for body dissatisfaction in both sexes, but we found that there were other risk factors like late puberty in boys and overweight at preadolescence in girls.
