摘要
【目的】了解贫困农村儿童生长发育、贫血和维生素A（vitamin A,VA）营养状况。【方法】随机抽取四川省某贫困县三个乡409名3-10岁农村儿童作为研究对象,测量其身高、体重,采用2000年美国CDC参考值计算Z评分和营养不良率;用氰化高铁血红蛋白法测定血红蛋白含量;用高效液相色谱法测定血清VA含量。【结果】男女儿童生长迟缓率分别为15.1%和26.1%,女童高于男童;低体重率分别为15.1%和20.1%;消瘦率分别为4.9%和2.2%;贫血患病率分别为16.9%和15.8%;VA缺乏率分别为7.6%和8.7%、可疑亚临床VA缺乏率分别为23.0%和25.3%。VA水平越低,贫血率越高。【结论】四川贫困农村儿童生长发育、贫血和VA营养状况不容乐观,以低年龄组较为严重,贫血与VA缺乏具有一致性,亟待解决。
[Objective] To evaluate the growth situation, the prevalence of anemia and vitamin A deficiency of rural children in Sichuan. [Methods] 409 children aged from 3 to 10 years were selected randomly from three countries of a poor county, Sichuan provinee. Their height and weight were measured, Z-scores were calculated by 2000 CDC growth charts for the United States. Hb concentration was determined by the cyanmethaemoglobin method and vitamin A concen tration was determined by high performance liquid chromatography（HPLC）. [Results] Among the children aged 3- 1 0 years , the prevalence of stunting , underweight and wasting for boys and girls were 1 5. 1 % and 2 6. 1 % , 1 5. 1% and 20.1%, 4.9% and 2.2% respectively. The prevalence of stunting for girls is higher than it for boys. The prevalence of a nemia was 16.9% and 15.8% for boys and girls. Vitamin A deficieney and subclinical vitamin A deficiency for boys and girls were 7.6% and 8.7%, 23.0% and 25.3%. With the vitamin A concentration increased, the prevalence of anemia de creased. [Conclusions] It＇s necessary to improve the nutritional status of rural children in Sichuan, especially the children aged less than 6 years old.
