This study examines the biological influence of infant death on subsequent fertility in three Asian countries--Indonesia, Nepal and Sri Lanka, comparing the birth interval between two consecutive births up to the sixth birth by survival status of the preceding infant among breast-feeding women not using contraception. There is consistent evidence of biological influence in each of the three countries. Infant death shortens birth intervals by up to 30%, though its influence varies between the countries.
This study examines the biological influence of infant death or subsequent fertility in 3 Asian countries (Indonesia, Nepal, and Sri Lanka), comparing the birth interval between 2 consecutive births up to the 6th birth by survival status of the preceding infant among breast feeding women not using contraception. Data are from the respective national fertility survey agencies in collaboration with the World Fertility Survey. The women were all married and 50 years old or less. The sample sizes were 9136, 5940, and 6813 for Indonesia, Nepal, and Sri Lanka, respectively. The study compares subsequent fertility responses of women according to their infant mortality experience and examines the biological effect by comparing mean birth intervals of women who lose an infant with those of women whose infant survives. Results show that women who lose an infant have consistently shorter mean birth intervals than those whose child survives infancy. Infant death results in a shorter mean birth interval by up to about 30%, 27%, and 28% in Indonesia, Nepal, and Sri Lanka, respectively. In general, the influence is strongest in Indonesia and weakest in Nepal. This variation may be attributed to the effect of breast feeding on fertility, which in turn is subject to influences such as maternal nutrition and the intensity of breast feeding. In all 3 populations, the biological effect is the strongest in the 1st birth interval, by up to 10%, probably because of higher fecundability in early married life and cultural pressure to have a child.
