目的:了解贵州省少数民族地区5岁以下儿童血清铁蛋白、血红蛋白的分布情况及缺铁性贫血患病情况,为制定儿童营养改善政策提供科学依据。方法:采用随机分层抽样的方法,收集贵州省龙里县和惠水县5岁以下儿童的静脉血和指尖血,用放射免疫法测定血清铁蛋白,用氰化高铁法测定血红蛋白。采用SPSS19.0软件进行统计分析。结果:在抽样地区5岁以下儿童缺铁性贫血患病率为21.1%。血清铁蛋白的平均值为36.6μg/L,血红蛋白的平均值为124.1 g/L,血清铁蛋白与血红蛋白呈正相关。结论:6~12个月龄的儿童由于辅食添加不及时,当地饮食习惯等原因造成儿童在12~24个月龄时血清铁蛋白及血红蛋白均出现最低值。加强和普及婴幼儿时期科学喂养及儿童营养知识,有益于儿童健康成长。
Objective: To understand the distribution of serum ferritin, hemoglobin and the prevalence of iron deficiency anemia in children under 5 years of age in minority areas of Guizhou province, and provide a scientific basis for formulating children nutrition improvement policy. Methods: The venous blood and fingertip blood were collected from children under 5 years of age in Longli County and Huishui County of Guizhou Province by random stratified sampling method. Serum ferritin was measured by radioimmunoassay and hemoglobin was measured by cyanidation and high speed iron. Using SPSS19.0 software for statistical analysis. Results: The prevalence of iron deficiency anemia in children under 5 years of age in the sampled area was 21.1%. The mean serum ferritin was 36.6 μg / L, the average hemoglobin was 124.1 g / L, and serum ferritin was positively correlated with hemoglobin. CONCLUSION: Children aged 6-12 months have the lowest values of serum ferritin and hemoglobin in children aged 12-24 months due to improper supplementing of food supplement and local dietary habits. Strengthen and popularize the scientific feeding and child nutrition knowledge in infants and young children, which will benefit the healthy growth of children.
