婴幼儿血红蛋白水平与喂养状况的关系分析

Analysis on the relationship between hemoglobin level and feeding status of infants

目的研究婴幼儿血红蛋白（Hb）水平与喂养状况的关系,探讨与婴幼儿铁营养状况不佳相关的饮食危险因素,为婴幼儿贫血防治提供可操作性方法。方法采用横断面研究方法,对北京市海淀区519例6~30个月龄婴幼儿进行Hb测定,由家长完成问卷调查。结果研究发现6~12个月龄是儿童贫血高危年龄段,贫血患病率为12.56%。进食红肉频次与Hb水平有显著相关性（RR=0.150,P=0.001）。结论喂养中饮食因素是导致婴幼儿铁营养状况不佳的主要原因。在基层儿童保健服务中可以把Hb在110~115 g/L这部分儿童作为预防贫血的窗口期,为基层儿童保健医生落实早期干预和使婴幼儿保持良好的营养健康状态提供参考依据。通过监测婴幼儿Hb水平对婴儿期贫血早期干预,使婴幼儿保持良好的营养健康状态,是儿童保健服务重点。

Objective To research the relationship between hemoglobin level and feeding status of infants,explore the dietary risk factors of poor iron status,and provide operational methods for prevention and treatment of anemia in infants. Methods A cross- sectional study was conducted among 519 infants aged 6- 30 months old in Haidian District,Beijing,hemoglobin detection was performed,the parents were asked to finish the questionnaire. Results Infants aged 6- 12 months old were high risk of anemia,and the prevalence rate of anemia was 12. 56%. Frequency of eating red meat was significantly correlated with hemoglobin level（ RR = 0. 150,P = 0. 001）. Conclusion Diet is the key point of poor iron status of infants. Hb level ranging from 110- 115 g / L is the window for prevention of anemia in these infants,which can provide reference for implementation of early prevention by child health care doctors in primary hospitals and maintaining good nutritional health status of infants. Conducting early intervention of infantile anemia by monitoring hemoglobin levels of infants and keeping the infants at good nutritional health status are key points of child health care service.
