Summary

Vitamin A deficiency remains a major public health problem in developing country worldwide. Young Children are considered to be at greatest risk of deficiency. However, there is little information on the vitamin A requirement of Chinese children. In the present study, about 400 children aged between 4 and 9 years old in a kindergarten and an elementary school of Shiyan City were screened before admission by questionnaire and anthropometric measurement. The vitamin A status of children was assessed by serum vitamin A level, relative dosage reaction and stable-isotope dilution technique. At the same time, their dietary vitamin A intakes were estimated by weighted-food dietary survey. The dietary vitamin A requirement in young children was determined on the basis of dietary vitamin A intakes in Children with adequate vitamin A level.
