The effect of duration of breast feeding on the occurrence of acute otitis media in children under three years.East Afr Med J. 1993 Oct; 70(10):632-4.EA
A case control study of 140 children below the age of three years with acute otitis media was conducted to study the short duration of breast feeding as a risk factor. 83% of the patients experienced the first attack of acute otitis media during infancy. 25% of them were breastfed for less than six months compared to only 10% in the control group. The mean duration of breast feeding was significantly shorter in the study group 8.6 months (sd = 7.9) as compared to the control group 13.7 months (sd = 6.5); p < 0.001 (t = 5.9). Thus short duration of breast feeding is a risk factor of acute otitis media in early childhood.
