title: Prevalence of eating disorders in Argentine boys and girls, aged 10 to 19, who are in primary care. A two-stage community-based survey.
abstract: The objective of this paper is to describe the prevalence of eating disorders (ED) in Argentina, in a randomly assigned national community-based sample of 1,231 girls and 740 boys in primary care, aged 10 to 19.9. A two-stage design was followed; subjects were screened with a self-report measure (EDE-Q4), and diagnosed with an expert-based interview (EDE-120D). Height, weight and BMI were measured and five subscales of the SCL90-R were completed. More than one quarter (a 26.4%) of the sample had a BMI greater than the 90th percentile, and these accounted for 48% of the suspected cases of ED. Only 42% returned for the EDE-12 interview; diagnosis was confirmed for 137 cases (6.9% of the total sample): 6.6% BED; 0.05% BN, and 0.3% EDNOS other than BED. Binge eating and restraint of food intake related directly to BMI and purging behaviors were very rare. More subjects than expected were found to be overweight and this related directly to the diagnosed ED. Psychological distress was directly related the presence of eating disturbances.
