The prevalence of vitamin A deficiency was estimated in 366 rural children in the age group of 1 to 15 years. In a systematically selected subsample of 90 children, the dietary intake of vitamin A was assessed. The prevalence of vitamin A deficiency signs ranged from 24.1 to 34.8%. The adequacy of dietary intake of vitamin A ranged from 8 to 12% when compared with the recommended dietary allowance. The dietary intake of children with and without vitamin A deficiency was not different (p greater than 0.05). The main source of beta carotene in the diet was cereals accounting for 47.9% of the total beta carotene intake.
对366名1至15岁的农村儿童进行了维生素A缺乏症患病率的估算。在系统选取的90名儿童子样本中，评估了维生素A的膳食摄入量。维生素A缺乏体征的患病率在24.1%至34.8%之间。与推荐膳食摄入量相比，维生素A的膳食摄入量充足率在8%至12%之间。有和没有维生素A缺乏症的儿童的膳食摄入量没有差异（p大于0.05）。饮食中β-胡萝卜素的主要来源是谷物，占β-胡萝卜素总摄入量的47.9%。
