Breast-feeding and human immunodeficiency virus.

Breast-feeding provides nutritional, immunological, and psychological benefits. It protects children from mortality and morbidity associated with diarrheal diseases, pneumonia and other infections. Breast feeding has also been shown to prolong the interval between births and thereby improve child survival and maternal health. However, studies suggest that in certain populations, breast feeding may account for nearly 14% of perinatal human immunodeficiency virus type 1 (HIV-1) transmission. It is therefore important that the risk of HIV-1 infection through breast feeding be weighed against the morbidity and mortality associated with bottle feeding. This paper discusses the literature dealing with breast feeding in women with HIV-1 infection. Specifically, the review addresses the issues surrounding infant mortality in areas of different HIV-1 prevalence where breast-feeding or bottle-feeding may be employed. Analysis suggests that the benefits of breast-feeding or bottle-feeding may be employed. Analysis suggests that the benefits of breast-feeding can substantially outweigh the putative risk of HIV-1 transmission unless the prevalence of HIV-1 infection is high or the difference in mortality between breast-fed and bottle-fed infants is very low.
