The study analyzed iron deficiency without anemia (IDWA) in 100 nonpregnant women aged 16–45 years with normal hemoglobin (≥11 g/dL) in March–August 2024. Iron deficiency, defined as serum ferritin <15 μg/L or serum iron <10 μmol/L, was found in 41% of participants. Univariate analysis showed an association with history of breastfeeding (crude OR=9.13, 95% CI: 3.32–25.11, p<0.001) and anemia (crude OR=5.51, 95% CI: 2.10–14.40, p<0.001). After multivariable adjustment, the following factors remained significant: history of breastfeeding (adjusted OR=6.72, 95% CI: 2.01–22.44, p=0.002) and history of anemia (adjusted OR=4.92, 95% CI: 1.56–15.03, p=0.015). Underweight BMI had an increased estimate (adjusted OR=2.84, 95% CI: 0.68–11.83, p=0.154), but was not statistically significant. The model was satisfactory (Hosmer-Lemeshow χ²=3.21, p=0.921; VIF<2.0). A comprehensive iron assessment is recommended in women with a history of breastfeeding or anemia.
