This study aims to investigate the prevalence of anemia in children and adolescents with autism, between 3 and 18 years old, through a retrospective review in medical records. Additionally, items relating to food selectivity and/or restriction were assed. A total of 118 medical reports were reviewed concerning hematimetric parameters (serum ferritin, iron, hemoglobin, hematocrit, mean corpuscular volume, and red cell distribution width).
We found that 28.07% had anemia based on hemoglobin, according to the WHO; in these patients, 21.5% had some type of food selectivity.
