| Categories of anemia according to hemoglobin level | Low blood lead level <10 μg/dl (n = 22) No (%) |
High blood lead level ≥10 μg/dl (n = 38) No (%) |
Test of significance |
|---|---|---|---|
| No anemia (Hb level ≥11 g/dl) | 16 (72.7) | 14 (36.8) | x2 = 10.5 p = 0.01 |
| Mild anemia (Hb level 10-10.9 g/dl) | 1 (4.5) | 11 (28.9)* | |
| Moderate anemia (Hb level 8-9.9 g/dl) | 4 (18.3) | 5 (13.2) | |
| Severe anemia: (Hb level < 8 g/dl) | 1 (4.5) | 8 (21.1)* | |
* p = < 0.05
