Objective: To analyze the changes of blood lead levels and related factors in Yinchuan children. Methods: A total of 6 323 blood lead levels from 6 to 6 years old in Yinchuan City were measured from 2004 to 2008 for five consecutive years. Results: The level of blood lead decreased year by year. The level of lead in blood of full-child care children was higher than that of scattered children in the first three years. The level of lead in children of older age was higher than that of children in younger age. The blood lead level of children in younger age group was higher than that of children in older age group. The linear regression analysis showed that the level of blood lead in children may be related to the following factors: mother’s education, parents’ occupation, housing age, whether they often eat puffed food, Agents and so on. Conclusion: Children lead poisoning showed a declining trend year by year.
