Figure 1: Percent of Children Tested For Lead at or Around Age One Year and at or Around Age Two Years; 1998 - 2004 Birth Cohorts (1998 to 2007 Blood Lead Test Data)1,2, New York State Excluding New York City

Figure 1 shows the percent of children who received at least one blood lead screening test at or around age one year (9 months to < 18 months) and the percent of children who received at least one blood lead screening test at or around age two years (18 months to < 36 months) for children born in the years 1998 through 2004. These measures correspond to the ages at which universal blood lead testing is required in NYS. Of children born in NYS in 2004, 60.6 percent received at least one lead test at or around age one year. Of children born in NYS in 2004, which is the latest cohort for which complete data are available, 51.6 percent received at least one lead test at or around age two years.3

Trend data show improvements in the percent of children receiving blood lead screening tests at age one and two years. A 22.7 percent increase in testing rates at age one year was observed between 1998 and 2004 birth cohorts (49.4 percent of children born in 1998 compared to 60.6 percent of children born in 2005). A 33.7 percent increase in testing at age two years was observed between 1998 and 2004 birth cohorts (38.6 percent of children born in 1998 compared to 51.6 percent of children born in 2004).

2000 54.2 41.3
2001 54.7 40.2

Footnotes

  1. At or around age one year is defined as 9 months to < 18 months and at or around age two years is defined as 18 months to < 36 months.
  2. Birth Cohorts beyond 2004 are not included in this analysis because those children had not yet reached 36 months of age by 2007.
  3. Children may be counted in each of the defined age categories and therefore each separate age group does not represent an unduplicated count of children and should not be added together.
