Pediatric eating disorders for 10 years | Ramírez-Sánchez F, et al. Actual Med. 2020; 105(811): 182- 189 184 20 children with EDs were selected for this study. The sex ratio was 3:1; 75% of the patients were wo- men and 25% men. 70% of patients had AN (93% in girls). Of them, 25% evolved to BN. The clinical data related to the debut of EDs and the first visit, are described in table 1. The age of onset was earlier in boys than in girls; however, the mean time of illness before the first consultation was shorter in girls. 43% had a lower weight than P10 at the first visit. The median weight loss before the first evaluation was 11 kg, although they maintained the same amount of lean mass. In BIA, most of the patients were in normal-low ran- ges in fat and lean mass, for its references (% in table 1).
