Abstract
Objective While coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2), has had global impact in all populations, certain
groups of patients have experienced disproportionate rates of morbidity and mortality.
The purpose of this study was to assess the relationship between COVID-19 disease
severity, demographic variables, race and ethnicity, and social determinants of health
among pregnant patients in a diverse urban population.
Study Design A retrospective analysis was performed of all pregnant patients diagnosed with COVID-19
at two urban tertiary care centers in Houston, TX between March and August 2020. Maternal
demographic, COVID-19 illness criteria, and delivery characteristics were collected.
The Centers for Disease Control and Prevention Social Vulnerability Index (SVI) and
COVID-19 Community Vulnerability Index (CCVI) were obtained based on a patients' census
tract of residence. Analyses compared persons with asymptomatic, mild, or severe-critical
disease at diagnosis.
Results A total of 317 persons tested positive for COVID-19 during this time period. Asymptomatic
persons were more likely to be diagnosed at later gestational ages, but there were
no other differences in baseline maternal characteristics. Persons with more severe
disease had greater social vulnerability specifically for housing and transportation
than those with mild disease (mean SVI [standard error]: 0.72 [0.06] vs. 0.58 [0.2],
p = 0.03). Total SVI, total CCVI, and other themed SVI and CCVI indices were not significantly
different between groups.
Conclusion In this cohort of pregnant persons infected with SARS-CoV-2, an association was shown
between disease severity and increased vulnerability in living conditions and transportation.
Drivers of the pandemic and COVID-19 outcomes are complex and multifactorial, and
likely change over time. However, continued efforts to accurately identify and measure
social determinants of health in medicine will likely help identify geographic areas
and patient populations that are at risk of higher disease burden. This could facilitate
preventative and mitigation measures in these areas in future disaster or pandemic
situations.
Key Points
-
SVI and CCVI estimate social determinants of health.
-
COVID-19 is associated with housing and transportation vulnerability.
-
Social determinants contribute to disease burden in pregnancy.
