Abstract

Objectives: To determine the status of anemia, deficiencies of iron and vitamin A in women prior to the first pregnancy in Cam Khe District, Phu Tho Province (CK-PT). Subjects and methods: A cross sectional study was conducted on 411 women from 18 to 30 years old, who have never been pregnant, living in CK-PT. The evaluation of the status of iron deficiency was based on the following biochemical indexes: Transferrin receptor, Ferritin; body iron; some indicators to exclude infection were C-Reactive Protein (CRP) and Alpha 1-Acid Glycoprotein (AGP). Hb indicator was used to evaluate the anemia status. The evaluation of the vitamin A status was based on the following indexes: serum VitA and Retinol binding protein. Results: The prevalence of depleted iron stores in the anemic group was 10.1% that was higher than that of the non-anemic group (3.2%) with p<0.01. In iron-deficient group, the mean RBP concentration was 1.06 ± 0.39 μmol/L which was lower than that in normal-iron status group (1.15 ± 0.41 μmol/L) and mean CRP concentration was 0.3 (0.1; 0.9) mg/L which was higher than that of the group of normal-iron status (p<0.01). Conclusion: The prevalence of anemia in the women prior to the first pregnancy in Cam Khe Phu Tho was 20.7% that was an average level of public health significance, among the anemic subjects, 43.0% non-infectious subjects that were iron deficient; the prevalence of iron deficiency was 37.9%; the prevalence of vitamin A-deficiency was 10.2%.
