目的分析某院儿童保健门诊中婴儿期缺铁性贫血(iron deficiency anemia,IDA)喂养方式及辅食添加的早晚与婴儿期缺铁性贫血的关系,有效的降低其患病率。方法采用整群随机抽样的方法选取该院儿童保健门诊中2009年5月～2010年5月0～1岁婴儿815例,排除疾病因素,通过体格检查,家长问卷,调查其喂养方式及辅食添加的早晚将患儿分为实验组(n=396),是指无论采取何种喂养(母乳或人工或混合)均于4～6个月添加辅食;对照组(n=419),是指无论采取何种喂养(母乳或人工或混合)均于4～6个月未添加辅食。两组统一采用BASIC血细胞全自动分析仪测血常规。结果实验组贫血发生率是19.2%,对照组贫血的发生率是37.5%。差异有统计学意义(P﹤0.01)。结论无论采取何种喂养(母乳或人工或混合)均于4～6个月添加辅食其贫血的发生率低于对照组,因此正确的儿童喂养行为可以有效的预防和减少婴儿期IDA患病率。
Objective To analyze the relationship between infantile iron deficiency anemia (IDA) feeding patterns and iron deficiency anemia in infants and children, and to reduce the prevalence of iron deficiency anemia. Methods A total of 815 infants from 0 to 1 year-old in the outpatient clinic of child health from May 2009 to May 2010 in the hospital were selected by cluster random sampling method to exclude the disease factors. The physical examination and parents questionnaire were used to investigate the feeding mode and supplementary food (N = 396) means that no matter what kind of feeding (breast milk or artificial or mixed) are added in 4 to 6 months of complementary food; control group (n = 419), that no matter Feeding (breast milk or artificial or mixed) were not added in 4 to 6 months complementary food. Two groups using BASIC blood cells automatic analyzer blood test. Results The incidence of anemia was 19.2% in the experimental group and 37.5% in the control group. The difference was statistically significant (P <0.01). Conclusion No matter what kind of feeding (breast milk or artificial or mixed) were added in 4 to 6 months, the incidence of anemia is lower than the control group, so the correct behavior of children feeding can effectively prevent and reduce the prevalence of IDA in infancy .
