| 目的了解近期北京市0～6岁儿童血铅水平及其影响因素。方法采取分层整群随机抽样的方法。2001年5～7月调查北京市常住人口中0～6岁儿童2262名。采用石墨炉原子吸收法进行微量血中铅含量的测定,并做相关因素问卷调查。结果北京市0～6岁儿童血铅水平均值为96.8μgL,血铅值≥100μgL为35.7%,血铅值≥200μgL为2.5%。农村儿童铅中毒为43%,明显高于城区和郊区儿童。2岁组铅中毒为45.1%高于其他年龄组。男童血铅平均值100.2μgL明显高于女童血铅平均值93.0μgL(P<0.01)。不喝或偶喝牛奶、居室距繁华马路≤50m、家庭居住1层楼房或平房为儿童高血铅的主要危险因素。结论目前北京市儿童血铅水平≥100μgL的比例不容忽视,应对重点人群采取行之有效的干预措施 |

| Objective To observe blood lead level and related risk facto rs among children of 0-6-y ear old in Beijing.Methods Stratified-clustered-random sampling and simple random sampling were used.A total of 2262 children of 0-6 years old were investigated from May to July 2001.They were permanent residents in Beijing.Blood lead level was tested by graphite atomizer absorption spectro pho tometer.At the same time, related factors were investigated using a standardized questionnaire.Results The mean lead level of children in Beijing was 96.8 μg L with 35.7% of those ≥100 μg L, and 2.5% ≥ 200 μg L.The propo rtion of lead poisoning was sig nificantly hig her in rural children (P <0.01).The pro portion of lead poisoning in 2-year-old g roup was hig her than that in o ther age g roups.The propor tion of lead poisoning in boys was significantly higher than that in girls(P <0.01).The following factors mig ht serve as majo r risk factors related to child lead poisoning, such as, never or rarely drinking milk, living in nearby highways (less than 50 meters)o r living in the first floo r bungalow, and so on.Conclusion The blood lead lev el of ≥100 μg L among Beijing children appeared to be a big problem.Decision-makers should pay more a ttention to prevent bloo d lead level being high, and to cure these children who suffered in lead poisoning.Effective interventio n measures on these target populations should be taken |
