Influence of the COVID-19 pandemic on social determinants of health among an inner-city obstetrical population

BACKGROUND: Social determinants of health are a well-described influencer of pregnancy-related morbidity and mortality. It is unclear how societal changes secondary to the COVID-19 pandemic altered the social determinants of health among pregnant patients. OBJECTIVE: This study aimed to investigate differences in the social determinants of health among patients who experienced pregnancy before and during the COVID-19 pandemic. STUDY DESIGN: This was a secondary analysis of an ongoing prospective cohort study examining the social determinants of health in postpartum patients at a single inner-city academic medical center. The planned secondary analysis was to compare the social determinants of health between patients that experienced societal changes before the pandemic and patients that experienced societal changes during the pandemic. Patients were included in the pandemic group if they delivered on or after March 30, 2020; moreover, patients in the pandemic group were compared with those who delivered before March 30, 2020 (referent group). Medical records were used to collect sociodemographic, pregnancy, and infant outcome data. The study participants were interviewed to collect detailed information regarding their perceived social, emotional, and physical environment as indicators of social determinants of health. Generalized linear modeling estimated the influence of social determinants of health on births during the COVID-19 pandemic. RESULTS: Overall, 577 patients were enrolled in the study, of which 452 (78%) delivered before the COVID-19 pandemic and 125 (22%) delivered during the pandemic. Patients who delivered during the pandemic were more likely to report limited social or emotional support (relative risk, 1.62; 95% confidence interval, 1.02–2.59) and higher race-based discrimination (relative risk, 1.59; 95% confidence interval, 1.00–2.53). Mothers in the prepandemic group were more likely to have used federally funded programs, such as Medicaid, food stamps, and the Special Supplemental Nutrition Program for Women, Infants, and Children, during their pregnancy. Furthermore, the referent group reported more limited access to transportation. In addition, mothers in the prepandemic group were more likely to initiate prenatal care at a later gestational age and have fewer total prenatal care visits. CONCLUSION: The COVID-19 pandemic created unprecedented changes in pregnancy care, and these were reflected in social determinants of health. It is imperative that we focus on the social determinants of health that were mitigated during this time and their effects on maternal and infant health.
