This is the first large population-based study of demographic risk factors for elevated lead in Texas children. It summarizes data on 92,900 children covered by Medicaid screened for blood lead during the first 6 months on 1993 in Texas. The highest percentage of elevated lead levels (14.3%) was in children 25-36 months of age, with slightly lower percentages in those younger (13% of 19-24 months) and older (12% of 37-48 months) with blood lead levels greater than 10 μg/dl. The group with the highest percentage of elevated blood lead levels was 2-4-year-old African American males (17.3%), making this subgroup 3.5 times higher than the group with the lowest percentage - white girls over age 4 (4.8%). Males had higher blood lead levels for all ages and ethnic groups. Three principal risk factors were found for excessive blood lead in children: ethnicity, gender, and age; this is consistent with the second National Health and Nutrition Examination Survey (NHANES II) and Phase I of the NHANES III results demonstrating ethnicity and income association with lead in children in the United States.
