铅中毒是全世界普遍存在但是可以预防的一种疾病,虽然美国儿童血铅水平正在下降,预计到2010年仍会有50万儿童血铅水平≥100μg/L。要达到这个国家目标还需要转变公众的健康意识,美国肯塔基州杰斐逊县(包括路易斯维尔市)采用CDC推荐的铅测试实验测试当地高风险儿童,利用铅中毒风险因子的知识制定发展预防策略。血铅测试定在路易斯维尔市附近的铅中毒高发区,特征是住房建在1950年前,价值小于5万美元,血铅浓度≥100μg/L的儿童,并对这些因素和其他干涉因子进行评价,在1996~2000年间出生的年龄为9~24月的儿童中,在高风险家庭的儿童由64.5%增加到73.7%;低风险家庭即住房建在1950年后,价值大于5万美元的家庭出生的儿童比例没有显著性改变。研究证明科学知识在公众健康习惯建立方面的应用,利用监督和其他数据有效的评价,对铅中毒高风险儿童进行检测,增加铅污染小的住房,使公众能保护他们的孩子避免铅暴露。
Lead poisoning is a ubiquitous but preventable disease in the world. Although the level of blood lead in American children is declining, it is estimated that there will still be 500,000 blood lead levels ≥100μg / L by 2010. To achieve this national goal, there is also a need to change public health awareness. Jefferson County, Kentucky, including the City of Louisville, uses CDC’s recommended lead test to test high-risk children in the area and use the knowledge of lead poisoning risk factors to develop developmental prevention strategies. The lead test is located in a high prevalence area of lead poisoning near Louisville and is characterized by children who were built before 1950 and had a value of less than $ 50,000 and a blood lead level of 100 μg / L or more and those and other interventions Among children aged 9-24 months born between 1996 and 2000, the number of children in high-risk families increased from 64.5% to 73.7%; that of low-risk families, ie, houses built after 1950, valued at more than $ 50,000 The proportion of children born did not change significantly. Research has demonstrated the application of scientific knowledge in establishing public health habits, using surveillance and other data to evaluate effectively the detection of children at high risk of lead poisoning, increasing the housing stock where lead is polluted and enabling the public to protect their children from lead exposure.
