Cross-sectional analysis reveals prevalence of iron deficiency anemia in early pregnancy, suggesting need for universal screening.

To assess the prevalence of non-anemic iron deficiency (NAID) in early pregnancy and identify associated clinical characteristics.
Cross-sectional study design with English- and Spanish-speaking adults ≥18 years
Participants completed surveys on medical history, diet, and underwent laboratory testing for iron deficiency
Iron deficiency was defined by ferritin and transferrin saturation levels, while anemia was defined by hemoglobin levels
54% of participants had non-anemic iron deficiency, 5% iron deficiency anemia, and 41% non-anemic iron repletion
Significant differences in hemoglobin, mean corpuscular volume, and ferritin between IDA/NAID and non-anemic iron repletion groups
The prediction model achieved an Area Under the ROC curve of 0.68, indicating moderate accuracy for predicting iron deficiency

Sarah E. Detlefs (2025) studied this question.
