Objective:To compare the efficacy of vitamin A supplementation with weekly iron supplementation on the iron and vitamin A status of preschoolers in suburb Chongqing,China. Methods:183 1~6 years old children who suffered from iron deficient anemia or vitamin A deficiency were randomly divided into three groups,and were arranged to receive 60 mg iron/week or 50 000 IU vitamin A capsule/week or 10 mg vitamin B 1 /week (placebo) for 20 weeks. Results:20 weeks after supplementation,Hb increased significantly in vitamin A group and iron group by 10 4 g/L and 8 9g/L,respectively but there is no difference between the groups ( P >0 05);Serium retinol increased significantly in vitamin A supplement group by 0 137 μmol/L( P <0 01),while the increase of serium retinol in iron supplementation group is not significant( P >0 05) Conclusion:Weekly supplementation of vitamin A capsule has the same effect on the increase of Hb concentration with the weekly supplementation of iron Therefore in the region where IDA and VAD exist at the same time,vitamin A supplementation is one of the good methods to improve the iron and vitamin A nutritional status
