An unknown risk group of lead poisoning: the gypsy children
1Departamento de Pediatría, Facultad de Medicina, C/Ramón y Cajal, Valladolid, Spain.
Insights
Gypsy children have significantly higher average blood lead levels (PbB) than Caucasian children, indicating a higher risk of lead poisoning in this population group. This finding holds true for both iron-deficient and iron-sufficient children.
Area of Science:
- Environmental Health
- Pediatric Health
- Toxicology
Background:
- Iron deficiency is common in children and can affect lead absorption.
- Ethnic disparities in health outcomes, including lead exposure, are a public health concern.
- Understanding lead exposure risks in vulnerable populations is crucial for targeted interventions.
Purpose of the Study:
- To compare average blood lead levels (PbB) in iron-deficient gypsy and Caucasian children.
- To assess the prevalence of toxic PbB in these ethnic groups.
- To investigate PbB differences in children with normal iron metabolism.
Main Methods:
- Assayed blood lead levels (PbB) in 89 iron-deficient children (25 gypsy, 64 Caucasian).
- Established subgroups: iron-deficient without anemia and iron-deficient with anemia.
- Included 41 iron-sufficient children (11 gypsy, 30 Caucasian) as controls.
- Determined blood counts, red-cell indices, serum iron, serum ferritin, and PbB.
Main Results:
- Average PbB was significantly higher in gypsy (14.25 µg/dL) versus Caucasian (7.25 µg/dL) iron-deficient children (P < 0.01).
- Prevalence of toxic PbB (>20 µg/dL) was higher in gypsy (24%) versus Caucasian (1.5%) iron-deficient children (P < 0.01).
- Gypsy children also showed higher average PbB (10.23 µg/dL) than Caucasian children (5.65 µg/dL) with normal iron metabolism (P < 0.001).
Conclusions:
- Gypsy children represent a population group at increased risk of lead poisoning.
- Environmental factors likely contribute to higher lead exposure in gypsy children.
- Public health strategies should consider ethnic-specific risks for lead poisoning prevention.
Abstract:
The differences in average blood lead levels (PbB) between iron-deficient children of both gypsy and Caucasian origin were determined. PbB were assayed in 89 iron-deficient children (Group ID): 25 gypsies and 64 Caucasians. Two sub-groups were established: sub-group ID1, 57 iron-deficient children without anaemia (11 gypsies, 46 Caucasians), and sub-group ID2, 32 children with iron deficiency anaemia (14 gypsies; 18 Caucasians). Group IS composed of 41 iron-sufficient children (11 gypsies and 30 Caucasians) served as controls. Blood counts, red-cell indices, serum iron concentrations, serum ferritin, and PbB were determined for the entire study population. The average PbB for gypsy and Caucasian iron-deficient children, were 14.25 and 7.25 micrograms/dl (P < 0.01) respectively. The prevalence of iron-deficient children with toxic PbB (> 20 micrograms/dl) was higher in gypsies (24%) than in Caucasians (1.5%) (P < 0.01). A difference in average PbB between the two ethnic groups was also seen in children with normal iron metabolism (average PbB, 10.23 vs 5.65 micrograms/dl for gypsies and Caucasians, respectively, P < 0.001). CONCLUSION Gypsy children should be considered as a population group at risk of lead poisoning in our environment.
