  1. Dentine lead and intelligence prior to school entry : a statistical sensitivity analysis.

    Article - En anglais

    The relationship between circumpulpal dentine lead and IQ at age 4 years 10 months was examined in 164 urban children.

    Negative correlations were observed between dentine lead and IQ scores, but were reduced in magnitude after adjustment for social covariates.

    Analyses using errors-in-variables regression models indicated that the degree of this reduction depended on diffcult-to-verify assumptions regarding the magnitudes of (i) measurement error in the lead variable and the covariates, and (ii) possible changes in the caretaking environment resulting from conjectured effects of lead on the child's cognitive and behavioral development.
