Objective
To evaluate the clinical efficacy of vitamin A combined with iron in the treatment of iron-deficiency anemia in preschool children.

Methods
Ninety-two children were randomly divided into treatment group and control group, 46 cases in each group. The two groups were given ferrous succinate tablets orally, 5 mg/(kg·d), three times a day, for 30 consecutive days as a course of treatment. The treatment group was also given vitamin A capsules, 1 capsule/time, once a day, for 7 consecutive days, which was stopped for 3 days, and then resumed in the same pattern, within 30 days. The clinical efficacy, hemoglobin, serum ferritin, serum iron content and total iron binding capacity of the two groups were observed and compared before and after treatment.
Results
The hemoglobin, serum ferritin, serum iron content and total iron binding capacity in the treatment group were higher than those in the control group(P<0.05), and the curative effect was better than that in the control group(100.0% vs 80.4%)(P<0.05).
Conclusion
Vitamin A combined with iron is more effective than iron alone in the treatment of iron deficiency anemia in preschool children.
