Abstract：Objective To examine the blood lead concentration among preschool children in Taiyuan and risk factors, and to provide scientific evidence for intervention. Methods A total of 3406 healthy children, living in urban areas in Taiyuan, who came to seek routine care from September 2010 to December 2014 were enrolled. A self-designed questionnaire survey, included 6 categories and 65 factors, was conducted. The questionnaire was completed by the parents under the instruction of the medical staff. Factors included the demographic characteristics of children, family status, living environment, living habits and health status of children and current clinical manifestations. Blood samples were collected and blood lead concentration was determined by atomic absorption spectrometry. Results The average blood lead concentration of preschool children in Taiyuan was 31μg /L, it’s 32 μg /L for male and 29 μg /L for female, the prevalence of high blood lead was 0.7%. The average blood lead concentration of preschool children was 30 μg /L、31 μg /L、34 μg /L、30 μg /L for 3,4, 5 and 6 years old respectively, It’s 28 μg /L、29 μg /L、35 μg /L、33 μg /L、34 μg /L respectively from 2010 to 2014, and there was significantly differences. High blood lead concentration of preschool children was correlated with maternal education, wall paint of child's living room, paint falling of furniture, regular consumption of dairy products and nail biting. Conclusion Although the blood lead concentration and the prevalence of high blood lead of preschool children in Taiyuan was low, targeted interventions should be taken according to the risk factors to prevent lead poisoning.
