The aim was to assess iron status and dietary iron intake in a sample of premenopausal female regular and new blood donors.
Premenopausal women blood donors were invited to participate. Blood samples were analyzed for serum ferritin and hemoglobin. An iron checklist assessed dietary iron intake. Donors were classified as regular donors or new donors.
Twenty-one new donors (mean [SD] age, 28.6 [6.0] years; body mass index [BMI], 25.6 [4.5] kg/m(2) ) and 172 regular donors (mean age, 29.4 [5.5] years; BMI, 24.7 [3.8] kg/m(2) ) participated. Fifty percent of regular donors and 24% of new donors had depleted iron stores (serum ferritin <15 μg/L; difference p = 0.036). Dietary iron intake was higher in regular donors (mean [SE], 12.6 [0.7] mg/day) compared to new donors (9.9 [0.4] mg/day; p = 0.006). Eighty-five percent of regular donors and 79% of new donors met the estimated average requirement for iron.
Despite the fact that most of these donors had an adequate dietary iron intake, more than half of the blood donors had depleted iron stores. Increasing dietary iron intake through supplements and/or dietary means is expected to be necessary to maintain adequate iron status in this group.
本研究旨在评估绝经前女性定期献血者和新献血者样本中的铁状态和膳食铁摄入量。
邀请绝经前女性献血者参与。分析血清铁蛋白和血红蛋白。铁清单评估膳食铁摄入量。将献血者分为定期献血者和新献血者。
21 名新献血者（平均[SD]年龄，28.6[6.0]岁；体重指数[BMI]，25.6[4.5]kg/m2）和 172 名定期献血者（平均年龄，29.4[5.5]岁；BMI，24.7[3.8]kg/m2）参与了研究。50%的定期献血者和 24%的新献血者铁储量不足（血清铁蛋白<15μg/L；差异 p=0.036）。定期献血者的膳食铁摄入量较高（平均[SE]，12.6[0.7]mg/天），而新献血者的摄入量较低（9.9[0.4]mg/天；p=0.006）。85%的定期献血者和 79%的新献血者满足铁的平均需要量。
尽管这些献血者的膳食铁摄入量充足，但仍有一半以上的献血者铁储量不足。预计通过补充剂和/或饮食方式增加膳食铁摄入量将有助于维持这一群体的铁状态。
