摘　　要：目的了解东乡族和保安族7～14岁农村儿童维生素A(vitaminA,VA)水平差异。方法按照整群分层抽样方法抽取东乡族民族聚居区(甘肃省东乡县)和保安族民族聚居区(甘肃省积石山县)7～14岁农村小学生各57例作为研究对象,采用微量荧光测定法检测血清中VA含量。结果东乡族农村儿童血清VA平均水平为(1.41±0.42)μmol/L,无维生素A缺乏(VAD)者,其中亚临床维生素A缺乏(SVAD)者4人(占7.0%),可疑SVAD者10人(占17.6%);保安族农村儿童血清VA平均水平为(1.67±0.53)μmol/L,无VAD者,其中SVAD者1人(占1.7%),可疑SVAD者7人(占12.3%);两民族间儿童血清VA水平差异有统计学意义。不同年龄组儿童血清VA健康状况构成比差异有统计学意义,不同民族的男性儿童VA水平间差异有统计学意义,男女儿童SVAD和可疑SVAD上差异无统计学意义。结论两民族学龄儿童较多的还是存在SVAD及可疑SVAD现象,患SVAD及可疑SVAD的儿童应该是今后VA缺乏防治的对象。Objective To study the level of vitamin A of children aged 7～14 in the Dongxiang and Bonan ethnic ghettos.Methods Fifty-seven children aged seven to fourteen were sampled from rural areas in the Dongxiang and Bonan ethnic ghettos from Dongxiang Autonomous County and Jishishan region,Gansu Province.The vitamin A level in serum was detected using the fluorescence method.Results The average level of vitamin A in serum was（1.41±0.42）μmol/L for children aged seven to fourteen in the Dongxiang region,and of all the fifty-seven children,there was 4 SVAD（accounted for 7.0%）and 10 suspicious SVAD（accounted for 17.6%）.The average level of vitamin A in serum was（1.67±0.53）μmol/L for children aged seven to fourteen in the Bonan region,and of all the fifty-seven children,there was 1 SVAD（accounted for 1.7%）and 7 suspicious SVAD（accounted for 12.3%）.There was statistically significant difference in different national and aged groups,but no difference in SVAD and suspicious SVAD.Conclusions SVAD and suspicious SVAD exist in the Dongxiang and Bonan region,and the intervention of vitamin A supplementation should focus on children suffering from SVAD and suspicious SVAD.
