在1980、1990、1996年三年度的急性感染性和非感染性疾病,年龄为3个月～3岁的住院病例中,每年随机抽样180份,进行了营养性贫血发病情况的回顾性调查,并与1990、1996年济南地区0～3岁健康儿贫血发病情况做一比较.资料显示住院病儿总发病率3年分别为63.89%(115/180)、64.44%(116/180)、46.67%(84/180)(P<0.01),济南地区1990及1996年分别为37.80%、20.73%(P<0.01),两组贫血发病情况均有逐年下降趋势,但城乡之间发病率比较无差异(P>0.05);住院儿发病率都远远大于健康儿(P>0.05),其贫血程度均以轻度为主,但住院儿贫血程度较健康儿重,有重度贫血情况.住院病例母乳喂养儿逐年增多,3年分别为110/180(61.11%)、139/180(77.22%)、160/180(88.89%);其贫血发生率也逐年下降,3年分别为72/110(65.45%)、87/139(62.59%)、73/160(45.63%)(P<0.01).但3年度中人工喂养和混合喂养儿的贫血发生率未降.1996年84例贫血儿测定元素锌、铁、铜,其中有41例低于正常值,余者大都属正常范围偏低值,其中缺锌38例、缺铁37例,缺铜27例,绝大多数为锌铁同缺,而三者同缺也占相当大比例.
In the 1980, 1990, 1996 three years of acute infectious and non-infectious diseases, aged 3 months to 3 years of hospitalized cases, a random sample of 180, a retrospective survey of the incidence of nutritional anemia, And compared with the incidence of healthy children aged 0 ~ 3 years old in Jinan in 1990 and 1996. The data showed that the total incidence of sick children was 63.89% (115/180), 64.44% (116/180) and 46.67 % (84/180), respectively (P <0.01). The incidence of anemia in both groups was decreased by 37.80% and 20.73% respectively in Jinan and 1990 (P <0.01), but the morbidity between urban and rural areas was no significant difference (P> 0.05). The incidence of hospitalization was much higher than that of healthy children (P> 0.05), and the degree of anemia was mild, but the incidence of anemia in hospitalized children was heavier than that of healthy children. Breastfeeding children increased year by year, 110/180 (61.11%), 139/180 (77.22%) and 160/180 (88.89%) respectively in three years. The incidence of anemia also decreased year by year, reaching 72/110 65.45%), 87/139 (62.59%) and 73/160 (45.63%) (P <0.01), but the incidence of anemia in artificial feeding and mixed feeding did not decrease in 3 years.In 84 cases of anemia children Zinc Iron and copper, of which 41 were lower than normal, most of the remaining normal range of values are low, of which 38 cases of zinc deficiency, iron deficiency in 37 cases, 27 cases of copper deficiency, the vast majority of zinc and iron with the missing, while the three With the lack of people also account for a large proportion.
