- This document is also available as a graph in Portable Document Format (PDF, 15KB, 1pg.)
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 2002. These measures correspond to the ages at which universal blood lead screening is required in New York State. Of children born in NYS in 2002, 53.1% received at least one screening test at or around age one year, while 45.2% received at least one screening 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 year and at age two years. A 7.5% increase in screening rates at age one year was observed between 1998 and 2002 birth cohorts (49.4% of children born in 1998 compared to 53.1% of children born in 2002). A 17.1% increase in screening at age two years was observed between 1998 and 2002 birth cohorts (38.6% of children born in 1998 compared to 45.2% of children born in 2002).
|Birth Cohort Year||Percent Screened 9- <18 months||Percent Screened 18 - <36 months|
- 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.
- Birth Cohorts beyond 2002 are not included in this analysis because those children had not yet turned 36 months of age by 2005, and the opportunity for blood lead testing remained available after 2005.
- 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.
