Figures 11 and 12 summarize trends in the incidence of lead poisoning among children under age six years for the years 1998 - 2005, by BLL categories (10 - 14 mcg/dL, 15 - 19 mcg/dL, and ≥ 20 mcg/dL). These summary analyses compare the relative contribution of each BLL category for each year and over time.
Figure 11 shows the total number of incident cases for each of the three BLL categories defined for the years 1998 - 2005. Figure 12 shows the incidence rate for each of the three BLL categories defined for the years 1998- 2005. Both the total number of children and the proportion of children tested for lead and newly identified with confirmed EBLLs steadily declined across all BLL categories during this time period. 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.
