我们用光电比色法和微量毛细玻璃管法,测定了血红蛋白含量,红细胞数和血球压积等,了解北京市城区托幼机构、散居和郊区(半山区)的学龄前儿童缺铁性贫血发病情况,发现郊区儿童缺铁性贫血患病率明显高于市区托幼机构及散居的儿童。从各年龄组来看,7个月至2岁患病率最高。市区二个托儿所三天称重法膳食调查结果,儿童铁的摄取量平均为8.6mg,达不到供给量标准,而一幼儿园用记帐法膳食调查表明,这些儿童铁的平均摄取量超过供给量标准,达12.8mg,其贫血发病率显著下降。因此,北京市学龄前儿童尤其婴幼儿贫血的发生,膳食中铁供给不足可能是主要原因。
We measured the hemoglobin, erythrocyte count and hematocrit by photoelectric colorimetric method and capillary capillary tube method to understand the incidence of iron deficiency anemia in preschool children, diaspora and suburban areas (Mid-Levels) in Beijing Found that the prevalence of iron-deficiency anemia in suburban children was significantly higher than that of kindergartens and diasporas in urban areas. From all age groups, the highest prevalence was between the ages of 7 months and 2 years. Urban nursery two day three weighing method meal survey results, children’s iron intake average of 8.6mg, less than the supply standards, and a kindergarten accounting method using a meal survey showed that the average intake of iron in these children over Supply standards, up to 12.8mg, the incidence of anemia decreased significantly. Therefore, the occurrence of anemia in preschool children in Beijing, especially in infants and young children may be the main reason for the insufficient supply of iron in the diet.
