Social vulnerability index and stillbirth: a secondary analysis of the Stillbirth Collaborative Research Network

The Centers for Disease Control and Prevention (CDC) created the Social Vulnerability Index (SVI) as a marker of societal vulnerability in a geographic county. SVI scores are divided into four themes: 1) socioeconomic status; 2) household composition & disability; 3) minority status & language; and 4) housing type & transportation. A higher SVI score suggests higher risk of vulnerability. We aimed to assess the association between the SVI and stillbirth in the United States among patients in the Stillbirth Collaborative Research Network (SCRN).
