RESUMEN
Iron status of 30 infants who had been breast fed until their first birthday and who had never received cow milk, medicinal iron, or iron-enriched formula and cereals was investigated; 30% were anemic at 12 months of age. The duration of exclusive breast-feeding was significantly longer among nonanemic infants (6.5 vs 5.5 months). None of the infants who were exclusively breast fed for 7 months or more and 43% of those who were breast fed for a shorter time were anemic. Infants who were exclusively breast fed for a prolonged period had a good iron status at 12 and 24 months.

A case-control study was conducted to study the association between breast-feeding and inguinal hernia. The case group was significantly less often breast fed than control subjects (odds ratio, 0.49; 95% confidence interval, 0.29 to 0.83) and exclusive breast-feeding was associated with a significant dose-response risk reduction. The association was not confounded by birth weight, maternal education, type of birth, number of other children in the family, or gender. Breast-feeding may represent a protective factor against inguinal hernia.
