补充儿童营养素对血红蛋白影响的干预研究

Intervention study on nutritional on hemoglobin among 6～24 months young infants

目的 分析补充儿童营养素对6～24个月婴幼儿血红蛋白含量的影响及铁缺乏的干预效果,为营养性贫血防治提供科学依据。方法 在广西缺铁性贫血高发区（横县、灵山县和宾阳县）,采用随机抽样方法在3个县8个乡抽取6～24个月婴幼儿（排除地中海贫血患者）作为营养干预试验研究对象,分4组进行比较研究,分别为A组（正常喂养＋营养素补充＋健康教育）、B组（正常喂养＋营养补充剂）、C组（正常喂养＋健康教育）、D组（正常喂养）。干预前、干预4个月、干预8个月后检测婴幼儿末梢血的血红蛋白,对不同组干预前后进行比较分析。结果 各月龄段婴幼儿干预4个月和8个月后,血红蛋白均高于干预前（P〈0.05）;12～24月龄婴幼儿干预后血红蛋白（Hb）高于对照组（t=2.78,P=0.006）;A、B组血红蛋白增值均高于C组和D组（LSD法,P〈0.05）。结论 补充儿童营养素可以提高婴幼儿血红蛋白含量,有利于改善婴幼儿贫血状况。

Objective To analyse the intervention effect of supplementation on children＇s nutrition hemoglobin （Hb） and iron deficiency in infants of 6-24 months,in order to provide a scientific basis for the prevention of nutritional anemia. Methods ＂Fhe survey was conducted according to random sampling in three counties of Heng, Lingsban and Binyang Courty where with a high incidence of iron deficiency anemia in Guangxi. Questionnaire survey and measuring Hb value were given to four groups aged 12-24 months infants excluding infants with thalassemia before,4 months later and 8 months af- ter the intervention. All A,B,C,D groups＂ intervention program were given normal feed,add nutrition combine health educa- tion,nutrition,health education and none intervention to A,B,C groups,respectively. Results Each month old infants＇ Hb after 4 months later and 8 months later were higher than those before intervention （P〈0.05）. 8 months after the interven- tion, the H b of the intervention group was higher than that of the control group showed in 12-24 month infants （t=2.78, P= 0. 006）. Both A/B groups were higher than C and D groups （analysis with LSD method,P〈0.05）. Conclusion Supplemen- tary nutrient for children can improve hemoglobin value,and it is conducive to improve the status of anemia in infants.
