目的了解徐汇区6月龄和12月龄低出生体重婴儿(LBW)和正常出生体重婴儿(NBW)贫血状况,分析其影响因素,为今后指导婴儿科学喂养,预防贫血提供依据。方法收集在本院定期体检并于6月龄和12月龄检查血常规的411例婴儿的保健资料,其中NBW和LBW分别为216和195例。应用计算机进行统计和卡方检验。结果 NBW6月龄及12月龄贫血检出率分别为18.1%和10.2%。LBW6月龄及12月龄贫血检出率分别为29.7%和9.7%。6月龄贫血检出率LBW高于NBW,差异有统计学意义(P<0.05)。12月龄LBW和NBW的贫血检出率相近,差异无统计学意义(P>0.05)。结论加强围产期保健,降低LBW的发生率,及时、合理地添加适量含铁辅食和铁剂是减少婴儿贫血的重要措施。
Objective To understand the anemia status of 6-month-old and 12-month-old low birth weight infant (LBW) and normal born weight infant (NBW) in Xuhui District, analyze its influencing factors and provide evidences for guiding scientific feeding and preventing anemia in infants. Methods The data of health care of 411 infants who were checked regularly at our hospital and checked blood routine at 6 months and 12 months of age were collected. The NBW and LBW were 216 and 195 respectively. Application of computer statistics and Chi-square test. Results The detection rates of anemia in NBW 6 months and 12 months were 18.1% and 10.2% respectively. The detection rates of anemic LBW 6 months and 12 months were 29.7% and 9.7% respectively. The detection rate of anemia at 6 months was higher than NBW, the difference was statistically significant (P <0.05). The detection rates of anemia in 12-month-old LBW and NBW were similar, with no significant difference (P> 0.05). Conclusion Strengthening perinatal care, reducing the incidence of LBW, timely and reasonable addition of iron supplements and iron supplements is an important measure to reduce anemia in infants.
