вот такое наблюдение от китайских докторов - и у взрослых жд/а повышает риск отита:

the relationship between iron metabolism and chronic suppurative otitis media (CSOM) in adults aged 20–60 years.

61 patients with CSOM and 61 controls included in the study. In the case group, 16 out of 61 patients (26.2%) had low ferritin levels and in the control group, 1 out of 61 patients (1.6%) had low ferritin levels (p < .001). In the case group, 6 (9.8%) of 61 patients had IDA, and in the control group, there were no patients with IDA among 61 patients (p = .027).

Iron deficiency may be considered a potential risk factor for chronic suppurative otitis media...
