Purpose: The purpose of this study was to examine the relationship between food security status and pregnancy outcomes. Methods: This was a single-center cross-sectional cohort study of postpartum women in Indianapolis, IN. A validated 10 question Household Food Security Survey module was used to assess food security for patients who spoke English, Spanish, or Haitian-Creole. Correlating with the USDA definitions of food security, total scores were “high,” “marginal,” “low,” and “very low.” Scores were analyzed as inadequate (marginal, low, or very low) vs. adequate (high) food security. If a score fell within any category but “adequate” food security, patients were provided with information on community resources. Prenatal and postpartum data were abstracted via chart review, collecting: standard demographics, language, parity, diagnosis of diabetes, diagnosis of hypertensive disorder(s), pre-pregnancy weight, weight at time of delivery, BMI at time of delivery, gestational age at delivery, Edinburgh Postnatal Depression Scale (EPDS) score, and delivery mode. Neonatal variables included: weight and sex. The primary outcome was occurrence of gestational diabetes (GDM). These outcomes were compared between patients who had adequate vs. inadequate food security. Logistic regression was used to examine the association between food insecurity and each of the dichotomous outcomes. Linear regression was used to model the relationship between sex-specific birthweight z-scores and food insecurity. All adjusted models included language and maternal age. The Indiana University institutional review board approved the study (IRB# 14116). Results: Two hundred six surveys were completed from June 2022 through December 2022. Ninety-three participants (45.4%, 95% CI 38.4-52.4%) were categorized as inadequate food security. The incidences of marginal, low, and very low food security were similar with 31, 30, and 28 participants, respectively. Race/ethnicity and language were different between adequate and inadequate groups (p=0.006 and 9 (aOR 4.32 95% CI 1.41-16.2). Conclusions: Inadequate food security status is highly prevalent in our patient population and was associated with racial/ethnic minority status and non-English speaking populations. Inadequate food security was found to be associated with a decreased odds of cesarean delivery and higher odds of postpartum depression.
