SCRN Chart Abstraction Prenatal Invasive Diagnostics Dataset in Stillbirth Collaborative Research Network Study

Data on whether prenatal invasive diagnostic procedures performed, timing, indication and results of procedure performed (Prenatal Invasive Diagnostic Procedures Form 04I)
Study Description
Population-based case–control study of the causes and extent of stillbirth (SB) in the United States. Participants were recruited at delivery between March 2006 and September 2008 from 59 urban and rural hospitals in 5 geographic areas. All women with SB and a representative sample of women with live births, oversampled for those delivering at <32 weeks gestation and those of African descent delivering at =32 weeks gestation, were approached for enrollment. Pregnancy terminations were excluded. The study included maternal interview, chart abstraction, placental exam, and postmortem (SB only). Data collection focused on surveillance and epidemiology, maternal disease, immunology and infections, placental pathology, and genetics. A subset of SCRN participants consented to re-contact which examined subsequent pregnancies and pregnancy complications, grief resolution, and whether life-course stresses and environmental factors were associated with an increased risk of SB. Biospecimens are available. Women who delivered a stillbirth or live birth and consented to participate in the Stillbirth Collaborative Research Network Study and their babies

研究概况
本研究为针对美国死胎（stillbirth, SB）病因与影响范围的基于人群的病例对照研究。研究于2006年3月至2008年9月期间，从覆盖5个地理区域的59家城乡医院的分娩人群中招募受试者。所有死胎产妇以及活产产妇的代表性样本均被纳入招募范围，其中针对妊娠<32周分娩者与非洲裔妊娠≥32周分娩者进行了过采样。妊娠终止病例被排除在本研究之外。
研究内容包括产妇访谈、病历摘录、胎盘检查以及仅针对死胎病例的尸检。数据收集聚焦于监测与流行病学、产妇疾病、免疫学与感染、胎盘病理学以及遗传学领域。
另有部分死胎协作研究网络（Stillbirth Collaborative Research Network, SCRN）的受试者同意接受再次随访，该随访研究考察了后续妊娠与妊娠并发症、悲伤情绪缓解情况，以及生命历程应激与环境因素是否与死胎风险升高相关。本数据集留存有生物样本。
本研究的纳入对象为同意参与死胎协作研究网络研究的死胎或活产产妇及其新生儿。
