Figure 7 shows the total number and rate of children under age six years newly identified with BLLs of 20 - 44 mcg/dL by year of testing1. In 2007, a total of 275 children were newly identified with BLLs of 20 - 44 mcg/dL, corresponding to an incidence rate of 1.3 per 1,000 children tested for blood lead in that year (0.13 percent of children tested).
Trend data show the dramatic improvement since 1998 in both the number and rate of children identified with incident BLLs of 20 - 44 mcg/dL since 1998. The total number of children newly identified with BLLs of 20 - 44 mcg/dL declined 59.9 percent between 1998 and 2007, from 686 children in 1998 to 275 children in 2007. The incidence rate declined 65.8 percent over the same period, from 3.8 per 1,000 children tested in 1998 to 1.3 per 1,000 children tested in 2005.
Under current NYS Public Health Law and regulations and CDC guidelines, children newly identified with BLLs of 20 - 44 mcg/dL receive risk reduction education, a detailed lead exposure assessment, nutritional assessment including iron status, developmental testing, environmental management and follow-up testing to track blood lead levels. Environmental management includes detailed assessments of all dwellings where children spend significant time and remediation of suspected sources of lead exposure identified through those assessments.
|Year of Test||Children with blood levels 20 - 44 mcg/dL||Rate per 1,000 children tested2|
- This category includes confirmed blood lead level incident results ≥ 20 - < 45 mcg/dL.
- Incidence Rate: Total number of children under age six years identified for the first time with confirmed BLLs of 20 - 44 mcg/dL divided by the total number of children under age six that had lead tests in that given year, multiplied by 1,000.
