Table 4.
Population attributable fractions (PAFs) for elevated Blood Lead Levels and Reading/Math ISAT Failure among Hispanic children.
| Hispanic Subgroup | Reading Failure | Math Failure | ||
|---|---|---|---|---|
| PAF (%) | 95% CI | PAF (%) | 95% CI | |
| All Hispanics a | 7.0 | 1.9, 11.9 | 13.7 | 7.8, 19.2 |
| Mexican-American b | 7.4 | 2.0, 12.5 | 14.5 | 8.2, 20.3 |
| Puerto Rican b | 6.4 | 1.7, 10.9 | 12.6 | 7.1, 17.7 |
| Other Hispanic b | 5.8 | 1.5, 9.8 | 11.3 | 6.3, 16.0 |
a For All Hispanic Children, model used to calculate PAF includes elevated blood lead level (5–9 vs. 1–4 µg/dL), gender, mother’s education, low-income, small for gestational age, preterm birth, child’s age at time of BLL, ISAT vs. Iowa, and Hispanic subgroup (Mexican-American vs. other Hispanic and Puerto Rican vs. Other Hispanic); b For individual Hispanic subgroups, model used to calculate PAF includes elevated blood lead level (5–9 vs. 1–4 µg/dL), gender, mother’s education, low-income, small for gestational age, preterm birth, child’s age at time of BLL, and ISAT vs. Iowa.
