The objective of this study is to assess the impact of maternal nativity on stillbirth in the US. We utilized the US Birth Data and Fetal Death Data for the years 2014-2017. Our analysis was restricted to live and stillbirths (N= of 14,867,880) that occurred within the gestational age of 20-42 weeks. The fetuses-at risk approach was used to generate stillbirth trends by gestational age. Adjusted Cox proportional hazards regression model was utilized to estimate the association between maternal nativity and stillbirth. Overall, the gestational week-specific prospective risk of stillbirth was consistently higher for native-born than their foreign-born mothers. Foreign-born mothers were 20% less likely to experience stillbirth than their native-born counterparts (AHR = 0.80; 95% CI = 0.78-0.81). Delineating the factors influencing the observed effect of maternal nativity on birth outcomes should be a research priority to inform strategies to address adverse birth outcomes in the US.
本研究的目的是评估在美国产妇出生地对死产的影响。我们使用了2014 - 2017年美国出生数据和胎儿死亡数据。我们的分析仅限于孕龄在20 - 42周内发生的活产和死产（N = 14,867,880）。采用风险胎儿法按孕龄生成死产趋势。使用调整后的Cox比例风险回归模型来估计产妇出生地与死产之间的关联。总体而言，本国出生的母亲在特定孕周的死产预期风险始终高于外国出生的母亲。外国出生的母亲经历死产的可能性比本国出生的母亲低20%（风险比=0.80；95%置信区间=0.78 - 0.81）。明确影响产妇出生地对出生结局观察效果的因素应是一项研究重点，以便为解决美国不良出生结局的策略提供信息。
