目的:了解我区3岁～5岁幼儿体内血铅含量水平及其影响因素。方法:通过问卷调查掌握幼儿的生活环境、习惯及健康体征等背景资料,并对接受调查的幼儿进行血铅检测,最后根据调查资料对检测结果进行比较分析。结果:所有接受调查的183名幼儿血铅均值为53.22μg/L;一年内进行过房屋装修的家庭其幼儿血铅均值为63.44μg/L,明显高于受调查儿童的血铅均值;生长发育迟缓的儿童血铅均值为65.12μg/L,亦明显高于受调查儿童的血铅均值。结论:在所有调查的环境行为因素中,房屋装修是导致我区幼儿血铅水平较高的主要原因;血铅水平升高会导致儿童生长发育迟缓。
Objective: To understand the level of blood lead levels and its influencing factors in children aged 3 to 5 years in our district. Methods: The questionnaire was used to master the background information of children’s living environment, habits and health signs. Blood lead levels were measured in children under investigation. Finally, the test results were compared and analyzed according to the survey data. Results: The average blood lead level of all 183 children surveyed was 53.22μg / L. The average blood lead level of the children who had been renovated in one year was 63.44μg / L, which was significantly higher than that of the surveyed children. The growth and development The average blood lead level of children who were retarded was 65.12 μg / L, which was also significantly higher than that of children surveyed. CONCLUSION: Among all the environmental behavioral factors investigated, house decoration is the main reason leading to higher blood lead levels in our district. Increasing blood lead level can lead to children’s growth retardation.
