摘要

國人鐵營養狀況之評估乃是以「國民營養健康狀況變遷調查，NAHSIT 1993-1996」第一年接受體檢之樣本為對象，總共分析樣本含男性935人，女性1,042人，分析率達91%。分析項目有血紅素、血清鐵蛋白、血清運鐵蛋白和血清鐵等之濃度，並據以計算血清運鐵容量與運鐵蛋白飽和度。缺鐵的評定採用鐵蛋白模式，即血紅素、運鐵蛋白飽和度與血清鐵蛋白值，三個指標中必須且僅有兩個指標不正常時表示缺鐵，以三個指標皆不正常表示缺鐵性貧血，兩者合計為總缺鐵率。整體而方，四歲以上國人總缺鐵率為男性2.1%，女性10.7%；缺鐵貧血率為男性0.2%，女性2.1%；國人缺鐵以無貧血症狀之潛伏缺鐵為主。國人鐵營養狀況有明顯的性別差異，鐵營養不良的問題以女性較男性為嚴重；男性之中，以成長中的青少年的5.7%和65歲以上老年人的13%缺鐵率較高；女性則四歲以上各年齡層均有缺鐵問題，13歲以上缺鐵率均達9%以上。比對鐵攝取量與缺鐵率的關聯可見，現行之13-18歲男女與19歲以上男性的鐵建議量足以滿足96%以上族群之生理需要，但是19-50歲女性在鐵攝取量達建議量93-3%時，仍有約10%的缺鐵率。如何有效改善女性鐵營養狀況應是重要的公共衛生議題。

Assessment of iron status was carried out on a nationally representative sample collected in the first year of ”The Nutrition and Health Survey in Taiwan (NAHSIT) 1993-1996”, which used a multi-staged, stratified, clustered design. A total of 935 males and 1,042 non-pregnant females aged 4 year and older were included, for whom indicators of iron status (hemoglobin, transferrin saturation, and serum ferritin) were measured. Iron deficiency was defined as having an abnormal value for any 2 out of 3 laboratory tests, and iron deficiency anemia was defined as having 3 abnormal values. Iron deficiency rate was 2.1% in males and 10.7% in females, and rate of iron deficiency anemia was 0.2% in males and 2.1% in females. Several groups in the population exhibited relatively high prevalence of impaired iron status: males older than 65 year (13%) and aged 13-18 year (5.7%), and females aged 4 year and older (5.7%-14.2%). In conclusion, iron deficiency is relatively common in females and should be considered an important issue in women’s health.
