[Evaluation of the screening strategy for lead poisoning in 1-to-3-year-old children monitored in maternal-child welfare centers in Paris].
A procedure for screening for lead poisoning was implemented since 1987 in the maternal and child health centers of 6 Paris "arrondissements". It relies on a screening of the children through environmental and clinical information. Our study aimed at evaluating this procedure and at estimating the prevalence of lead poisoning in the children aged 1 to 3 years old attending free maternal and child health centers in Paris. We did a cross-sectional survey of a sample of 512 children. A questionnaire concerning each child's risk factors was answered by the paediatric nurses of the clinics. Potential lead poisoning cases were detected by capillary determining of free erythrocyte protoporphyrins (FEP). Blood lead level (PbB) was measured in children with FEP > or = 350 micrograms/l. The prevalence rate of lead poisoning was estimated at 1.9% +/- 1.7% for a PbB threshold > or = 250 micrograms/l and at 9.6% +/- 3.5% for a PbB threshold > or = 150 micrograms/l. The detection procedure identified 4 children out of 5 with a PbB > or = 250 micrograms/l and 2 children out of 3 with a PbB > or = 150 micrograms/l.
