Objective: To evaluate the relationship between maternal ferritin (FS) and hemoglobin (Hb) levels with those of their newborns (RN). Materials and Methods: A correlational study was conducted, including singleton pregnancies at full term without complications, and their newborns delivered through normal childbirth. Pregnant women with chronic systemic diseases, infections, tobacco use, hemoglobinopathies, newborns with malformations, low birth weight, and prematurity were excluded. The sample size was estimated with 95% confidence and 90% statistical power. Pregnant women were consecutively recruited. FS was determined by chemiluminescence, and Hb by impedance in maternal venous blood and umbilical cord. Maternal anemia was defined as Hb<11g/dl, and low FS as FS<30ng/ml. Anemia and low FS in newborns were categorized by gender. Descriptive statistics, Pearson or Spearman's (r) correlation, Student's t-test, and Wilcoxon Rank-Sum test were employed. A significance level of p<0.05 was considered. Results: 74 pregnant women and their newborns were included. Maternal age was 26 years (IQR: 22-31) and gestational age was 39.06 ± 1.0 weeks. The median FS and Hb levels in newborns were significantly higher than in mothers (p=0.001). 36.4% of mothers had anemia. (mild or moderate in 96.3%), Hb ≥9g/dl in 94.6% and HD in 67.6%. No newborn had low FS or anemia. The overall analysis between maternal FS and Hb and newborn FS and Hb showed no significant correlation, but when maternal FS was <30ng/ml, the correlation was moderate and significant (r=0.339; p=0.01). There was no significant difference in anthropometric characteristics between newborns of anemic and non-anemic mothers. Conclusions: Mild to moderate maternal anemia with Hb≥9g/dl did not show a significant correlation with newborn FS and Hb. A significant correlation was found when maternal FS was <30ng/ml. This FS cutoff point needs validation for timely diagnosis and monitoring of low FS in the third trimester of pregnancy.
