Using data collected over a 12-month period (1977–78) from more than 15,000 hospital deliveries at a single maternity hospital in Tehran, Iran, we have examined the effects of previous pregnancy outcomes, breast-feeding and contraceptive use on birth spacing. The outcomes of previous pregnancies, particularly the most recent, significantly affect the length of the pregnancy interval, and so does breast-feeding. Pregnancy outcomes influence both breast-feeding and subsequent contraceptive behaviour, and breast-feeding adds to the degree of protection against pregnancy afforded by conventional contraception. Improved survivorship increases the length of pregnancy intervals most when it results in increased use of contraception and when breast-feeding is commonly practised for extended periods.
