LOW IRON STORES IN PREGNANT MEXICAN WOMEN AT TERM

Abstract
Objective: To document the iron status of Mexican pregnant women at term from a low-income group through serum ferritin determinations. To evaluate the influence of prenatal care (PNC), iron supplementation, and parity on iron stores at the end of pregnancy.Methods: Hemoglobin (Hb) and serum ferritin (SF) were measured in 201 low-income urban women with at term pregnancy. Women were divided in three groups. Group I: iron deficiency, SF<12µg/L, group II: borderline iron stores, SF12µg/L and <30µg/L, and group III: normal iron stores, SF>30µg/L. Results: 85.6% of the studied women (172) had empty iron stores, 10.4% (21) borderline and 4% (8) normal iron stores. Forty-six percent of the women (92) in the study group had iron deficiency anemia, as did 79(46%) of the 172 iron deficient women. Sixty five percent of the women did not attend PNC and 82% did not ingest iron supplements. Conclusions: A high prevalence of iron deficiency and iron deficiency anemia, scarce utilization of prenatal care services and poor ingestion of iron supplements was documented. A normal hemoglobin concentration was found whenever the serum ferritin concentration was >12µg/L. No correlation was found between maternal or fetal SF or Hb, and weight at birth
