甘肃省贫困地区6～24月龄婴幼儿贫血状况及其影响因素

  目的  了解甘肃省贫困地区6~24月龄婴幼儿贫血患病状况及其影响因素，为改善当地儿童贫血患病状况提供参考依据。  方法  采用多阶段抽样的方法，在甘肃省12个儿童营养改善项目县对6~24月龄婴幼儿及看护人进行调查，用t检验、方差分析进行血红蛋白含量的比较、用χ2检验进行患病率之间的比较、用Logistic回归分析模型进行影响因素的分析。  结果  3 188例有效数据中，贫血检出率为25.69%（819人），男童、女童中贫血检出率分别为24.54%、26.90%，不同性别间贫血检出率的差异无统计学意义（χ2=2.326，P=0.127），不同年龄组间贫血检出率的差异具有统计学意义（χ2=42.339，P < 0.001）；多因素分析结果表明:儿童月龄、儿童民族、家长对喂养知识的知晓率、儿童出生6个月后喂养方式、营养包的服用方式与贫血均存在相关性（均有P < 0.05）。  结论  甘肃省贫困地区6~24月龄婴幼儿贫血患病率较高，加强对看护人喂养知识及科学育儿的宣教，进一步落实营养包的有效服用，有助于改善儿童贫血患病状况。

Anemia prevalence and its influencing factors for the infants aged 6-23 months in poor areas in Gansu Province

  Objective  To understand the prevalence of anemia and its influencing factors in infants aged 6 to 24 months in poor areas of Gansu Province, and to provide reference for improving the prevalence of anemia in local children.  Methods  A multi-stage sampling method was used to conduct a survey on infant and caregivers, in the 12 children nutrition improvement project counties in Gansu Province. T-test and analysis of variance were used to compare the hemoglobin content, the chi-square test was used to compare the prevalence of anemia, and the Logistic regression model was used to analyze the influencing factors.  Results  Among the 3 188 effective data, the detection rate of anemia was 25.69% (819). The detection rate of anemia among boys and girls was 24.54% and 26.90%, respectively. There was no significant difference in the detection rate of anemia among different sexes (χ2=2.326, P=0.127). The detection rate of anemia between different age groups were statistically significant (χ2=42.339, P < 0.001); The results of multivariate analysis showed that children's age, children's ethnic groups, parents' awareness of feeding knowledge, the feeding method of 6 months after birth and the way of taking nutritional packs were associated with anemia (all P < 0.05).  Conclusions  The prevalence of anemia in infants aged 6 to 24 months in poor areas in Gansu Province was relatively high. Strengthening the education of caretakers' knowledge of guardian feeding and scientific child-rearing, and ensuring the nutrition packages intake can significantly reduce the prevalence of anemia prevalence in poor areas in Gansu Province.
