Despite substantial progress in reducing exposures to lead among children, as recently as 1991, 9% of children in the United States had blood lead levels (BLLs) of > or = 10 micrograms/dL (1)--levels that can adversely affect intelligence and behavior. In 1991, CDC recommended screening all children for lead exposure except those residing in communities in which large numbers or percentages previously had been screened and determined not to have lead poisoning (2). Subsequently, the California Department of Health Services (CDHS) issued a directive to all California health-care providers participating in the Child Health and Disability Prevention Program to routinely screen children for lead poisoning in accordance with the 1991 CDC guidelines (3). This report presents finding of BLL testing during 1992-1993 from a managed-care organization that provides primary-care services to Medicaid beneficiaries in several locations in California (i.e., Los Angeles County, Orange County, San Bernardino County, Riverside County, Sacramento, and Placerville).
尽管在降低儿童铅暴露方面取得了重大进展，但就在1991年，美国仍有9%的儿童血铅水平（BLLs）达到或超过10微克/分升（1）——这一水平会对智力和行为产生不利影响。1991年，美国疾病控制与预防中心（CDC）建议对所有儿童进行铅暴露筛查，但居住在之前已进行过大量筛查且确定无铅中毒的社区的儿童除外（2）。随后，加利福尼亚州卫生服务部（CDHS）向所有参与儿童健康与残疾预防项目的加利福尼亚州医疗服务提供者发布指令，要求他们按照1991年CDC指南对儿童进行铅中毒常规筛查（3）。本报告介绍了1992 - 1993年期间一家管理式医疗组织对加利福尼亚州多个地区（即洛杉矶县、橙县、圣贝纳迪诺县、里弗赛德县、萨克拉门托和普莱瑟维尔）医疗补助受益人的初级保健服务中血铅水平检测的结果。
