Abstract：
Little research has explored relationships between prenatal substance use policies and rates of maternal mortality across all 50 states, despite evidence that prenatal substance use elevates risk of maternal death. This study, utilizing publicly available data, revealed that state-level mandated testing laws predicted maternal mortality after controlling for population characteristics.
摘要：
很少有研究探讨产前物质使用政策与所有50个州的孕产妇死亡率之间的关系，尽管有证据表明产前物质使用会增加产妇死亡的风险。这项研究,利用公开数据，揭示了州一级的强制性检测法律在控制人口特征后预测了孕产妇死亡率。
