In a carefully constructed study that sought to capture all stillbirths in 5 defined geographic areas, the SCRN investigators enrolled every mother and stillborn neonate and also enrolled as controls 2 mothers and their liveborn neo-nate(s) (614 stillbirths and 1816 live births). Based on a comprehensive review of prenatal, intrapartum, and neonatal information, the authors confirmed known associations of stillbirth risk with maternal diabetes, obesity, smoking, mul-tifetal pregnancy, and black race, and identified increased stillbirth risk for women pregnant for the first time or living alone. Risk factors evident at the beginning of pregnancy had low positive predictive value and were associated with relatively few stillbirths, limiting the opportunities for early intervention.
