Figure 11 shows the total number of children newly identified with BLLs ≥ 10 mcg/dL, by age category (0 - < 9 months, 9 months - < 18 months, 18 months - < 36 months and 36 months - < 72 months) for each year from 1998 to 2007. This analysis was conducted to assess differences in the incidence of lead poisoning among young children of different ages and how those differences may be changing over time.
Overall, the total incidence of lead poisoning has declined over time in all age groups defined. These declines are most striking among children aged one year (9 months - < 18 months), two years (18 months - < 36 months) and three years to six years (36 - < 72 months), while incidence among children under age one year (0 - < 9 months) has been more stable.
The highest number of new cases of BLLs ≥ 10 mcg/dL occurred among children at or around age one year (9 months - < 18 months) in all years since 1999, followed by the number of cases among children at or around age two years (18 months - < 36 months). Far fewer cases were identified among children under age one year (0 - < 9 months) or over age three years (36 months - < 72 months).
