摘要

In 1996, the United States Preventive Services Task Force (USPSTF) provided recommendations for routine screening of asymptomatic children and pregnant women for elevated blood lead levels. This review updates the evidence for the benefits and harms of screening and intervention for elevated blood lead in asymptomatic children and pregnant women. We searched MEDLINE, reference lists of review articles, and tables of contents of leading pediatric journals for studies published 1995 or later that contained new information about the prevalence, diagnosis, natural course, or treatment of elevated lead levels in asymptomatic children aged one-five years and pregnant women. The prevalence of elevated blood lead levels among children and women in the United States, like that in the general population, continues to decline sharply, due primarily to marked reductions in environmental exposure, but still varies substantially among different communities and populations.
