What they found
Researchers estimated that a 40% hypothetical reduction in lead levels could lead to a 0.60 point mean difference in General Cognitive Index and 0.77 points in the perceptual scale for children.
What they studied
This study used data from the PROGRESS birth cohort in Mexico City to assess associations between integrated lead levels during pregnancy and early childhood and children's intellectual performance at 48 months.
Takeaways
The abstract focuses on the study's findings regarding lead exposure and cognitive outcomes; it does not provide personal how-to steps for individuals.
About this paper
This study was a target trial using data from the PROGRESS longitudinal birth cohort in Mexico City. It assessed lead exposure through multi-media biomarkers and children's intellectual functioning at 48 months of age.
