摘要

對48位孕婦採血，分析其血紅素值，血清鐵，TIBC和鐵蛋白濃度，輸鐵蛋白飽和度，紅血球紫質值，FEP:Hb比值等，以探討孕婦的鐵營養狀況。孕婦平均年齡28.7±4.3歲，懷孕週數6.7~42周。比較懷孕前、中、後期三組之差異可見，在懷孕中期組，血紅素值，血清鐵濃度，輸鐵蛋白飽和度和血清鐵蛋白濃度均顯著降低，其中血清鐵，輸鐵蛋白飽和度和血清鐵蛋白分別僅及前期組之79%、72%和31%；懷孕後期組輸鐵蛋白飽和度僅及前期組之54%，鐵蛋白則僅及25%，更有TIBC之顯著上升。鐵營養指標顯示本調查之孕婦血紅素值低11g/dl者佔33%，血鐵蛋白濃度低於10ng/ml者佔38%，輸鐵蛋白飽和度低於20%者佔35%，估計缺鐵之比例可能高達30%，以懷孕中、後期最為嚴重，體內鐵儲存量顯著減少。

並列摘要

The iron status of 48 pregnant women was investigated. Biological indices examined included hemoglobin, serum iron, total iron binding capacity, (TIBC) transferrin saturation, serum ferritin, free erythrocyte protoporphyrin (FEP), and FEP: Hemoglobin ratio. In the second trimester group, lower value was observed in hemoglobin, serum iron, transferrin saturation and serum ferritin, among which the last three indices was only 79%, 73% and 31% respectively of those in the first trimester group. In the third trimester group, transferrin saturation and serum ferritin was only 55% and 25% respectively of those in the first trimester group. In addition, TIBC was significantly higher in the third trimester. All the indices of iron status studied in pregnancy indicated that iron store was severely depleted in the second and third trimesters. It is estimated that 33% of the subjects studied had hemoglobin lower than 11g/dl, 38% had serum ferritin lower than 10ng/ml, and 35% had transferrin saturation lower than 20%.
