Maternal nutrition, prolonged lactation and birth spacing in Ethiopia

  • R. Jane Wenlock (a1) and R. W. Wenlock (a1)

Summary

Data from 375 Ethiopian mothers show lactations of between 25 and 30 months in the majority, very prolonged even by African standards. Maternal nutritional status, as shown by body weights, was low due to very low food energy intakes. With frequent suckling already raising prolactin levels, these very low energy intakes may also result in yet more prolactin secretion. New pregnancies are delayed and birth intervals extended beyond normal African standards by all these factors.
