ABSTRACT
<p><b>OBJECTIVE</b>To observe blood lead level and related risk factors among children of 0 - 6-year old in Beijing.</p><p><b>METHODS</b>Stratified-clustered-random sampling and simple random sampling were used. A total of 2 262 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 spectrophotometer. At the same time, related factors were investigated using a standardized questionnaire.</p><p><b>RESULTS</b>The mean lead level of children in Beijing was 96.8 micro g/L with 35.7% of those >/= 100 micro g/L, and 2.5% >/= 200 micro g/L. The proportion of lead poisoning was significantly higher in rural children (P < 0.01). The proportion of lead poisoning in 2-year-old group was higher than that in other age groups. The proportion of lead poisoning in boys was significantly higher than that in girls (P < 0.01). The following factors might serve as major risk factors related to child lead poisoning, such as, never or rarely drinking milk, living in nearby highways (less than 50 meters) or living in the first floor/bungalow, and so on.</p><p><b>CONCLUSION</b>The blood lead level of >/= 100 micro g/L among Beijing children appeared to be a big problem. Decision-makers should pay more attention to prevent blood lead level being high, and to cure these children who suffered in lead poisoning. Effective intervention measures on these target populations should be taken.</p>
