Figure 7: Incidence of Blood Lead Levels of 10 - 14 mcg/dL Among Children Under Age Six Years; 1998 to 2005 Blood Lead Test Data, New York State Excluding New York City.

Figure 7 shows the total number and rate of children under age six years newly identified with BLLs of 10 - 14 mcg/dL by year of testing.2 In 2005, a total of 1,497 children were newly identified with BLLs of 10 - 14 mcg/dL corresponding to an incidence rate of 7.7 per 1,000 children tested for blood lead in that year (0.77% of children tested).

Trend data show the dramatic improvement since 1998 in both the number and rate of children identified with incident BLLs of 10 - 14 mcg/dL. The total number of children newly identified with BLLs of 10 - 14 mcg/dL declined 56.2% between 1998 and 2005, from 3,415 children in 1998 to 1,497 children in 2005. The incidence rate declined 59.5% over the same period, from 19.0 per 1,000 children tested in 1998 to 7.7 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 10 - 14 mcg/dL receive risk reduction education, nutritional counseling and follow-up blood lead testing to monitor blood lead levels.

  1. Incidence Rate:Total number of children under age six years identified for the first time with confirmed BLLs of 10 - 14 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 ≥ 10 - < 15 mcg/dL.
