目的:探讨母亲孕期贫血及婴幼儿饮食情况等因素对婴幼儿贫血的影响。方法:采用病例对照研究的方法,筛选出0-3岁贫血患儿77例为贫血组,另按年龄分层随机抽取同地区非贫血婴儿77例作为对照组,获取两组婴幼儿系统保健资料,同时,回顾性追踪其母亲孕期保健资料。所得资料用t检验、x2检验和Logistic回归进行分析。结果:单因素分析显示,婴幼儿辅食添加种类、断乳后食品种类、既往铁剂添加史、母孕晚期血红蛋白浓度及红细胞计数与婴幼儿贫血有关;多因素非条件Logistic回归分析显示,母亲孕晚期红细胞计数和饮食结构与婴幼儿贫血有关(p<0.05)。结论:孕母晚期贫血与婴幼儿饮食结构的不合理,是婴幼儿缺铁性贫血的重要影响因素。
Objective: To investigate the effects of maternal anemia and infant diet on the anemia in infants and young children. Methods: A case-control study was conducted to select 77 anemia children aged 0-3 years old as anemia group. Another 77 non-anemia infants were randomly selected from the same area as the control group. At the same time, retrospective tracking of maternal health information. The data obtained using t test, x2 test and Logistic regression analysis. Results: Univariate analysis showed that infant feeding supplements, the type of food after weaning, the history of addition of iron, the late pregnancy hemoglobin concentration and erythrocyte count were related to infant anemia. Multivariate non-conditional Logistic regression analysis showed that the mothers’ Late erythrocyte count and dietary structure were associated with anemia in infants (p <0.05). Conclusion: The maternal anemia and the unreasonable diet structure of infants and young children are the important influencing factors of infantile iron deficiency anemia.
