Does prolonged breastfeeding adversely affect a child's nutritional status?

Lancet. 1988 Aug 20;2(8608):416-8. doi: 10.1016/s0140-6736(88)90411-4.

Abstract

In 202 children who visited a children's hospital in the city of Accra, Ghana, breastfeeding beyond the age of 19 months was found to be associated with malnutrition. The effect of weaning on food intake was then studied in 15 breastfed malnourished children in a rural community. Before weaning (complete cessation of breast-feeding) protein and energy intakes of all the malnourished children were about half those of 5 normal children. 10 of the malnourished children were weaned, and their intakes rose to the levels of the normal children; the 5 who continued breastfeeding maintained their low intakes. These results indicate that prolonged breastfeeding can reduce total food intake and thus predispose to malnutrition. They also suggest that in Ghana and other developing countries the proper weaning age may be about 18 months.

PIP: In 202 children who visited a children's hospital in the city of Accra, Ghana, breastfeeding beyond the age of 19 months was found to be associated with malnutrition. The effect of weaning on food intake was then studied in 15 breastfed malnourished children in a rural community. Before weaning, protein and energy intakes of all the malnourished children were about 1/2 those of 5 normal children. 10 of the malnourished children were weaned, and their intakes rose to the levels of the normal children; the 5 who continued breastfeeding maintained their low intakes. These results indicate that prolonged breastfeeding can reduce total food intake and thus predispose to malnutrition. They also suggest that in Ghana and other developing countries the proper weaning age may be about 18 months. It is suggested that, when breastfed children who are over 12 months old show reluctance to take supplementary foods, they should be weaned completely to enhance their food intake. It is also suggested that, in Ghana, breastfed children who eat well may be weaned at about 18 months without adverse effects on their health. However, in view of the major advantages of long-term breastfeeding, as well as the disadvantages, more work will have to be done to substantiate these observations.
