Abstract
Summary. In a community‐based prospective study, 6275 deliveries resulting in 6084 livebirths, 150 stillbirths (SB) and 167 neonatal deaths (NND) were monitored over a period of 3 years. The risk of an unfavourable outcome (SB or NND) in multiple pregnancies was more than ninefold that of singletons. Teenage mothers and those over 34 years of age ran nearly twice the risk of having an unfavourable outcome of pregnancy compared with mothers aged 20–29 years. First pregnancy and grandmultiparity (greater than eight previous pregnancies) carried a similar risk of an unfavourable outcome compared with mothers with 1–4 previous pregnancies. The most serious risk factor was the adverse outcome of the previous pregnancy. Compared with mothers whose last outcome had resulted in a livebirth surviving at least 30 days, mothers with a previous SB had seven times the risk (adjusted for age and parity) of SB and more than twice the risk of NND in the current pregnancy. Maternal illiteracy was associated with significantly higher risk of NND, and this rate decreased with increasing years of education. Frequency of antenatal visits had a marginally significant effect on the SB rate. Socioeconomic factors, diet and iron supplementation during pregnancy did not seem to affect the outcome.
