Background: COVID-19 is linked to multiple adverse pregnancy outcomes but with inconsistent evidence associating the disease with fetal growth restriction (FGR) and small for gestational age (SGA). There are limited data on the impact of COVID-19 on neonatal growth measurements, specifically microcephaly without SGA or low birth weight. We hypothesize that COVID-19 is associated with smaller neonatal head measurements without increasing the risk of small for gestational age. This relationship may be related to the timing of COVID-19 exposure in pregnancy. Methods: An Institutional Review Board (IRB) approved retrospective cohort study enrolled 140 COVID-19-infected and 136 COVID-19-uninfected patients. Inclusion criteria: (a) singleton birth between 28 April 2020 and 31 December 2022; and (b) maternal COVID-19 infection diagnosed via polymerase chain reaction (PCR). Exclusion criteria: Less than 12 years of maternal age, major fetal anomalies, and fetal loss < 15 weeks. The outcomes were a comparison of newborn growth measurements (length, weight, and head circumference (HC) at birth), Ponderal Index (PI), and development of SGA between SARS-CoV-2-infected and uninfected patients. Maternal and neonatal characteristics were descriptively summarized, and multivariate analyses and linear regression models were performed. Baseline maternal demographics did not differ amongst cohorts. Results: Compared to the uninfected cohort, COVID-19 diagnosed in the third trimester was associated with a lower neonatal HC compared to newborns of uninfected patients (β = −0.38 [0.38 SD lower], 95% CI −0.65 to −0.10, p = 0.024). There was no significant difference among cohorts in birth length, weight, or diagnosis of small for gestational age. Conclusions: We found that COVID-19 infection in the third trimester was associated with a lower neonatal head circumference without associated SGA. The cause underlying this association is unknown. Further research to determine the risk of neurotropic fetal infection by SARS-CoV-2, like ZIKA’s effect on the fetal immune system leading to microcephaly, is urgently needed.

Background/Objectives: Screening for food insecurity, while common practice in pediatric populations, remains novel in pregnancy. Food insecurity during pregnancy is associated with medical comorbidities that in turn confer additional obstetric risks to the maternal–fetal dyad. Few studies have evaluated the impact of interventions for patients with food insecurity in the prenatal period. This study first demonstrates the ease of FI screening in pregnancy using the Hunger Vital Sign™ and next assesses if providing patients with a referral to a registered dietician decreases the incidence of inappropriate weight gain in pregnant patients with food insecurity. Methods: A retrospective chart review was conducted from November 2019 to March of 2021 at a United States Northeast inner-city hospital-based clinic to identify patients with food insecurity in the prenatal period. All pregnant patients who screened positive for food insecurity were given an educational pamphlet with resources and offered a referral to a registered dietician. We compared the incidence of appropriate weight gain among these patients depending on whether they attended an appointment with a registered dietician. We defined appropriate weight gain following the recommendations of the Institute of Medicine (IOM) based on pre-pregnancy body mass index. Inferential statistics were performed to compare differences using univariate statistics, and multivariate regression was conducted to control for confounders, with an alpha of 0.05. Results: In total, 139 patients screened positive for food insecurity (FI); 52 (37.4%) attended an appointment with a registered dietician. Overall, 88 (61.9%) patients had inappropriate weight gain during pregnancy. Fewer patients who attended a visit with a registered dietician had inappropriate weight gain than those who did not attend a visit (27 [30.7%] vs. 61 [69.3%], p = 0.031, respectively). Both study groups’ demographics, comorbidities, and postpartum outcomes were comparable. Conclusions: We found that for pregnant individuals with food insecurity, consultation with a registered dietician was associated with a decrease in the incidence of inappropriate weight gain during pregnancy.
