Figure 9: Incidence of Blood Lead Levels of 20 - 44 mcg/dL Among Children Under Age Six Years; 1998 to 2005 Blood Lead Test Data, New York State Excluding New York City.

Figure 9 shows the total number and rate of children under age six years newly identified with BLLs of 20 - 44 mcg/dL by year of testing.2 In 2005, a total of 308 children were newly identified with BLLs of 20 - 44 mcg/dL, corresponding to an incidence rate of 1.6 per 1,000 children tested for blood lead in that year (0.16% 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 55.1 % between 1998 and 2005, from 686 children in 1998 to 308 children in 2005. The incidence rate declined 57.9% over the same period, from 3.8 per 1,000 children tested in 1998 to 1.6 per 1,000 children tested in 2005.

Under current New York State 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 screening, 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.

Footnotes

  1. 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 screening tests in that given year, multiplied by 1,000.
  2. This category includes confirmed blood lead level incident results ≥ 20 - < 45 mcg/dL.
