目的探讨4月龄后常规补铁与母乳喂养对婴儿缺铁性贫血发生情况的影响。方法选取50例在该院进行系统管理的4月龄后的婴儿进行跟踪研究。从中随机选取25例婴儿作为对照组,仅给予母乳喂养,另25例作为观察组,在给予母乳喂养的同时辅以右旋糖酐铁口服液。两组婴儿均于6个月龄时进行检查,对比两组婴儿缺血性贫血发生情况及生长发育情况。结果观察组婴儿缺铁性贫血发生率(8.0%)明显低于对照组(32.0%),差异有统计学意义(χ~2=4.5,P<0.05);观察组婴儿体重[(8.2±0.5)kg]及身高[(67.4±2.1)cm]与对照组[(8.1±0.6)kg、(67.5±1.8)cm]比较差异无统计学意义(t值分别为1.048、0.17,均P>0.05);观察组婴儿血红蛋白(Hb)水平[(124.7±5.1)g/L]及红细胞平均体积(MCV)[(100±0.3)fl]明显优于对照组[(99.4±2.9)g/L、(70±0.3)fl],差异有统计学意义(t值分别为21.719、10.740,均P<0.05)。结论 4月龄后给予婴儿母乳喂养的同时配合常规补铁可显著降低缺铁性贫血发生率。
Objective To investigate the effects of routine iron supplementation and breastfeeding on iron deficiency anemia in infants after 4 months of age. Methods Fifty infants of 4 months old who were systematically administrated in this hospital were followed up. Twenty-five infants were randomly selected as control group, only breastfed and the other 25 as observation group supplemented with dextran oral liquid while breastfeeding. Two groups of infants were examined at 6 months of age, compared two groups of infants with ischemic anemia and growth and development. Results The incidence of iron deficiency anemia in observation group was significantly lower than that in control group (32.0%, χ ~ 2 = 4.5, P <0.05) kg] and height [(67.4 ± 2.1) cm] compared with those in control group [(8.1 ± 0.6) kg, (67.5 ± 1.8) cm], respectively ) In observation group was significantly higher than that in control group [(99.4 ± 2.9) g / L], and the level of hemoglobin (Hb) [(124.7 ± 5.1) g / (70 ± 0.3) fl], the difference was statistically significant (t values were 21.719,10.740, all P <0.05). Conclusion After 4 months of age, infant breastfeeding and iron supplementation can significantly reduce the incidence of iron deficiency anemia.
