摘　　要：目的了解学龄儿童维生素A,C,E摄入量对其反复呼吸道感染(RRTI)发病的影响,为调整和改善该年龄段儿童人群的微量营养素摄入提供指导。方法选取唐山市524名小学一～六年级学生进行健康状况和膳食营养状况调查,记录反复呼吸道感染的发生状况;营养计算器V1.6转换数据,SPSS11.5软件进行多因素分析。结果学龄儿童维生素A的摄入量均低于RNI;维生素C的摄入量随年龄增长而增多,但只有11～12岁组达到RNI;维生素E的摄入量高于AI。524名学龄儿童中,RRTI占12.6%,男、女生RRTI差异无统计学意义;各年龄组RRTI构成差异有统计学意义(P<0.05),低年龄组较高。维生素A,C,E摄入量与RRTI发病均呈正相关;剔除影响因素,学龄儿童维生素A,C,E摄入量均对RRTI的发病有影响(β值分别为-0.018,-0.011,0.010,P值均<0.05)。结论建议根据情况增加学龄儿童维生素A,C,E的摄入量,必要时给予合理补充。Objective To study effect of school children＇s intake levels of vitamin A, C, E to Recurrent Respiratory Tract Infection（ RRTI）, in order to provide guidance for adjusting and improving intake of micronutrients.

Their intake of vitamin C raised with age, but only 11 - 12 age group up to RNI. Their intake of vitamin E was higher than AI. The RRTI rate among them were 12.6 %, and it had no gender difference. But there were significant differences between different age groups （ P 〈 0.05 ）. Low age group was higher. Intake of vitamin A, C, E had positive relations with RRTI. Deducting other influential factors, intakes of vitamin A, C, E among school children all had influence to RRTI （β = -0. 018, -0. 011,0. 010 ,P 〈 0. 05 ）.
