RESUMO
Objectives. To determine the changes in stillbirth rates in singleton pregnancies in a stable population over a period of 50 years. Methods. Stillbirth rates for singleton pregnancies where the fetus weighed 1 000 g or more were collected from 1962 to 2011. From 1972 to 2011; rates included fetuses weighing 500 g or more at birth. Results. When the birth weight was 1 000 g or more the stillbirth rate declined from 70 to 12.6 per 1 000 births; and when the birth weight was 500 g or more it dropped from 34.2 to 24.5. The decline was very much slower towards the end of the study period. Conclusion. To achieve further sustained reductions in stillbirth rates; healthcare workers should continue to emphasise quality of healthcare; but they should also address and prevent specific conditions associated with stillbirth; such as smoking and drinking during pregnancy
