Figure 6: Incidence of Blood Lead Levels ≥ 10 mcg/dL Among Children Under Age Six Years; 1998 to 2005 Blood Lead Test Data, New York State Excluding New York City

Figure 6 shows the total number and rate of children under age six years newly identified with BLLs ≥ 10 mcg/dL by year of testing. In 2005, a total of 2,283 children were newly identified with BLLs ≥ 10 mcg/dL, corresponding to an incidence rate of 11.8 per 1,000 children tested for blood lead in that year (1.18% of children tested).

Trend data show the dramatic improvement since 1998 in reducing both the number and rate of children identified with incident BLLs ≥ 10 mcg/dL. The total number of children newly identified with BLLs ≥ 10 mcg/dL declined 56.1% between 1998 and 2005, from 5,198 children in 1998 to 2,283 children in 2005. The incidence rate declined 59.3% over the same period, from 29.0 per 1,000 children tested in 1998 to 11.8 per 1,000 children tested in 2005.

These data are broken out by specific blood lead level categories in Figures 7 - 12.

  1. Incidence Rate: Total number of children under age six years identified for the first time with confirmed BLLs ≥ 10 mcg/dL divided by the total number of children under age six that had screening tests in that given year, multiplied by 1,000.
