Poster Session I
This is a secondary analysis of the SCRN, a case-control study of live births and stillbirths from 2006-2009. Data from the parent study were matched to the CDC’s 2010 Census tract SVI to create patient-level SVI scores, which were divided into quartiles. SVI themes and subthemes were compared overall and by quartiles between stillbirth and term live births ( >37 weeks’). A subgroup analysis of SVI in setting of stillbirth stratified by time of demise (intrapartum (IP) versus antepartum (IP)) was performed. Multivariable logistic regression was performed adjusting for differences in bivariate analysis.
Results: There was no difference in SVI score between 982 stillbirths and 2,240 term live births overall (66.3% vs 66.4%, p=0.5) or in each subtheme. However, the least vulnerable SVI quartile for housing and minority status & language themes were associated with reduced odds of stillbirth (aOR [95% CI] 0.53 [0.27-0.98]) & aOR 0.53 [0.27-0.98], respectively) versus term live births. When analyses were stratified into timing of stillbirth, IP stillbirths had higher SVI scores than term live births in the subtheme minority status & language (aOR 1.03 [95% CI 1.01-1.06]), particularly in the most vulnerable SVI quartile (aOR 3.74 [95% CI 1.51-12.4]). There were otherwise no differences in SVI score comparing IP or AP stillbirth to term live birth.
Conclusion: SVI scores were similar overall between those who had stillbirth and term livebirths. However, incorporating SVI into routine care may help identify those at increased risk for IP stillbirth.
