喂养方式和辅食添加对婴儿缺铁性贫血的影响

Effects of Different Feeding Ways and Food Supplement on Infants Iron Deficiency Anemia

目的探讨不同喂养方式和辅食添加对婴儿缺铁性贫血的影响。方法母乳喂养组167例,婴儿出生后4个月内给予纯母乳喂养;混合喂养组104例,婴儿出生后即给予混合喂养,在婴儿3-4月、6-7个月进行北京市儿童系统管理体检时检测儿童缺铁性贫血的发生率。结果婴儿3-4月龄时混合喂养组婴儿缺铁性贫血检出率为48.1%,明显高于纯母乳喂养组的31.2%,两组比较差异有统计学意义（P〈0.05）。添加辅食后,两组婴儿6-7个月时缺铁性贫血发生率比较差异无统计学意义（P〉0.05）。结论出生后婴儿纯母乳喂养可减少缺铁性贫血发生率;适时、适量、合理添加辅食是减少缺铁性贫血的有力措施。

Objective To observe the effects of different feeding ways and food supplement on infants iron deficiency anemia.Methods According to the type of feeding,the infants were categorized into two groups：breast feeding and mixed feeding,to detect the incidence of iron deficiency anemia in 3 to 4 months and 6 to 7 months during systemic physical checkup.167 cases in breastfeeding group,with exclusive breastfeeding in four month after birth;104 cases in mixed feeding group,with mixed feeding after birth.Results The incidence of iron deficiency anemia in mixed feeding group of 3 to 4 months infants is 48.1%,higher than 31.2% of breastfeeding group,a statistically significant difference（P〈0.05）.After food supplement,there is no statistically significant difference between the incidence of iron deficiency anemia of two groups in 6 to 7 months infants（P〉0.05）.Conclusion Exclusive breastfeeding could lower the incidence of iron deficiency anemia after birth.Adding supplement food timely and appropriately is the drastic measure to lower the incidence.
