It is difficult to determine who is at risk for stillbirth as it can happen to any pregnant woman regardless of her age, ethnicity, or background. However, there are certain factors that increase the likelihood of a stillbirth. Factors such as advanced maternal age (35+ years), pre-existing medical conditions (diabetes, high blood pressure, etc.), prior stillbirths, and smoking during pregnancy can all increase the risk of stillbirth. Additionally, pregnant women carrying multiples, those with certain infections, and those with a history of pregnancy or delivery complications are also more likely to experience stillbirth.
