- Abstract
Objective. To analyze the association between documented sources of lead exposure (PbES) and lead concentrations in capillary blood (BPb) in children 1-4 years old and to quantify the relative contribution of different PbES at national and regional levels. Materials and methods. We used data from Encuesta Nacional de Salud y Nutrición (Ensanut 2022). We considered using lead-glazed traditional pottery (PbTP), environmental, and para-occupational as exposure sources. We estimated the prevalence of intoxication (BPb≥5.0 µg/dL) and geometric means of BPb concentration. We adjusted regression models for BPb (logarithmic scale) and Shapley-Owen decomposition of R² to assess the contribution of each PbES. Results. The studied PbES explains 6% of the total national variability of BPb; 87.3% is explained using LBVPb, 4.2% by environmental exposure sources, and 1.3% by para-occupational exposure. The relative contribution of PbTP use varies across regions, ranging from 38.1 to 76.8%. Some regions show the relevance of PbES of environmental exposure but not para-occupational. Conclusions. Our results confirm that among the studied PbES, the use of PbTP is the most frequently reported. Likewise, the results suggest that the population does not identify the currently documented PbES.
