Risk factors for recurrent otitis media.

Risk factors for recurrent otitis media were studied in 115 otitis-prone children. A group of 323 children was used as controls. The care of children in day care centers, parental smoking and a low socioeconomic status of the family were associated with recurrent otitis media. The duration of breast feeding, the child's age at introduction of cow's milk-based feeding and allergy were not associated with recurrent otitis media.
