A survey was performed to know blood lead level (BLL) of children under seven and the risk factors of high BLL in Chengdu, China in 2004. The mean BLL in children under seven in Chengdu was 63.88 microg/L. The detection rate of high BLL was 8.21%. Chengdu is a moderate popular region of lead poisoning. Substitute of breast milk, living at the base floor or in one-storey houses and houses near the streets are the risk factors of high BLL (p < 0.05). The risk of anorexia, spasm and impaired concentration is higher in children whose BLL is higher than those whose BLL is lower (p < 0.05). Living circumstances, feeding patterns, and eating habits affect BLL, which in turn influences children's health status.
2004 年在中国成都进行了一项调查，旨在了解 7 岁以下儿童的血铅水平（BLL）和高 BLL 的危险因素。成都 7 岁以下儿童的平均 BLL 为 63.88μg/L。高 BLL 的检出率为 8.21%。成都属于铅中毒中度流行地区。母乳代用品、居住在底层或一层房屋以及靠近街道的房屋是高 BLL 的危险因素（p<0.05）。血铅水平较高的儿童出现厌食、痉挛和注意力不集中的风险更高（p<0.05）。生活环境、喂养方式和饮食习惯会影响 BLL，进而影响儿童的健康状况。
