【目的】观察铁强化大米对改善学生缺铁性贫血的作用。【方法】按照随机、双盲法将228例缺铁性贫血学生分为强化组和对照组,分别食用铁强化大米或普通大米的营养午餐。治疗前后测查血红蛋白(Hb)和血清铁蛋白(serum ferritin,SF)。【结果】①强化组在铁强化营养餐后Hb≥120 g/L占71.55%(78/109),对照组占40.91%(45/110);强化组Hb≥125 g/L占60.55%(66/109),对照组占30.0%(33/110),差异均有显著性。干预后强化组Hb均值较干预前明显增高;对照组Hb均值也有提高,但低于强化组,两组比较差异有显著性;②强化组SF水平显著增长,对照组SF也有增长,但强化组的SF值显著高于对照组的SF值,差异有显著性(P<0.05)。【结论】铁强化大米能纠正学生的缺铁性贫血,提高体内的铁储存。
【Objective】 To observe the effect of iron fortified rice on improving iron deficiency anemia in students. 【Methods】 According to the randomized, double-blind method, 228 iron-deficiency anemia students were divided into two groups: the intensive group and the control group. Hemoglobin (Hb) and serum ferritin (SF) were measured before and after treatment. 【Results】 (1) In the fortified group, Hb≥120 g / L accounted for 71.55% (78/109), control group accounted for 40.91% (45/110); Fortified group Hb≥125 g / L accounted for 60.55% (P < 66/109), while the control group accounted for 30.0% (33/110), the difference was significant. The mean Hb in the intensive group was significantly higher than that before the intervention; mean Hb in the control group was also increased, but lower than that in the intensive group. There was significant difference between the two groups (P <0.05) .②The level of SF in the intensive group increased significantly, SF value was significantly higher than that of the control group, the difference was significant (P <0.05). 【Conclusion】 Iron fortified rice can correct iron deficiency anemia in students and increase iron storage in the body.
