Data from the Demographic and Health Survey of Bolivia, 1989, are used
to examine the influence of breastfeeding and birth spacing on infant
and child mortality during the first two years of life. Event-history
techniques show that illness which leads to the cessation of lactatio
n, rather than the cessation of lactation for other reasons, is the do
minant factor contributing to mortality. Where lactation is separated
from the effect of illness, it had no effect on infant and child survi
val, except during the very early months of life. Short birth interval
s also increased the risk of dying during the first two years of life,
as did receiving ante-natal care from a midwife.
