A review of determinant factors of stillbirths in Malaysia

Abstract

Introduction : Stillbirth is one of the important adverse pregnancy outcomes that has been used as a health indicator for the measurement of the health status of a country especially for its obstetric care management. However, the aetiology of the occurrence of the stillbirth was commonly difficult to identify because of limitations in the classification system. Methods : A review of existing, available information published up to January 2007 on stillbirths in Malaysia was used to obtain the basic background on the determinant factors of stillbirths. Results : Malaysia, which is a fast developing country, reported a stillbirth rate in the range of 4 to 5 per 1000 births. Almost 30- 40% were recorded as normally formed macerated stillbirths. This was based on a rapid reporting system of perinatal deaths using the modified version of the Wigglesworth’s pathophysiology classification. Those of extreme maternal age (less than 19 years and more than 35 years), those reside in rural areas, of the ‘Bumiputera’ and Indian ethnic groups were at higher risk of stillbirth. On detailed analysis it was seen that the risks of having a normally formed macerated stillbirth increased among those who had a preterm delivery and hypertension. Stillbirth rates were also higher in those with shorter gestational age and in those with parity between 2 and 5. No other factors related to stillbirth were found in this review. Conclusion : This is a review based on existing published data which has a lot of limitation when it comes to analysing other important factors that might be related with the risk of the stillbirth. However, extreme maternal age and mothers from rural areas are the two factors that were persistently found in almost all literature. When these factors are combined with signs of pre term delivery, they indicate that close monitoring needs to be done.
