U.S. Maternal Vulnerability Index (MVI)

Surgo Ventures' Maternal Vulnerability Index (MVI) ranks the U.S. states and counties on indicators measuring drivers of poor maternal health outcomes. Maternal vulnerability is assessed based on 43 drivers grouped into six themes: (1) Reproductive Healthcare, (2) Physical Health, (3) Mental Health and Substance Abuse, (4) General Healthcare, (5) Socioeconomic Determinants, and (6) Physical Environment. The MVI captures factors that put birthing people at increased risk of adverse outcomes during pregnancy that may lead to morbidities and/or death. Data gaps on both maternal outcomes and their determinants constrain crafting evidence-based policies and interventions to address the maternal health crisis in the US. A growing body of evidence has found that the environment in which mothers live, work, deliver and raise their children can increase their risk of adverse health outcomes during and beyond pregnancy. Although data on these environmental and structural factors exist, the US MVI is the first nation-wide index to measure how contextual factors systematically expose populations of mothers to environments of lower or higher risk. State and local decision makers can use the tool to better understand where and why mothers are at increased risk for poor outcomes, to develop tailored, localized interventions and/or policies. Researchers can use the MVI, either alone or linked with other datasets, to provide a richer and more nuanced understanding of the drivers of poor maternal health outcomes in the US.

苏戈风险投资（Surgo Ventures）推出的孕产妇脆弱性指数（Maternal Vulnerability Index, MVI），针对美国各州及各郡县，以衡量不良孕产妇健康结局驱动因素的指标为依据进行排名。孕产妇脆弱性的评估基于43项驱动因素，分为六大主题：（1）生殖医疗保健（Reproductive Healthcare）、（2）身体健康（Physical Health）、（3）心理健康与物质滥用（Mental Health and Substance Abuse）、（4）基础医疗保健（General Healthcare）、（5）社会经济决定因素（Socioeconomic Determinants）以及（6）物理环境（Physical Environment）。该指数覆盖了使分娩人群在孕期发生不良结局风险升高的各类因素，此类结局可能引发并发症乃至死亡。当前孕产妇健康结局及其决定因素的数据缺口，制约了美国制定循证政策与干预措施以应对孕产妇健康危机的进程。

越来越多的研究证据表明，母亲生活、工作、分娩及养育子女的环境，会提升其孕期及产后不良健康结局的发生风险。尽管针对这些环境与结构性因素已有相关数据，但美国孕产妇脆弱性指数是首个全国性指数，用于量化评估情境化因素如何系统性地将孕产妇群体暴露于低风险或高风险环境之中。

各州及地方决策者可借助该工具，更清晰地掌握孕产妇不良结局风险升高的地域分布与成因，从而制定针对性的本地化干预措施与政策。研究人员可单独使用该指数，或结合其他数据集联用，以更全面、细致地解析美国不良孕产妇健康结局的驱动因素。
