  1. The effects of lead levels on the growth of word recognition in middle childhood.

    Article - En anglais

    The relationship between dentine lead levels and the development of word recognition abilities from 8 to 12 years of age was studied in a sample of 636 children drawn from a birth cohort of 1265 New Zealand children.

    Data were analysed by growth curve modelling methods to characterize the relationship between early lead levels and subsequent development of word recognition abilities.

    The results of this analysis showed:

    I) Before adjustment for confounding and other factors children who had lead levels of >=8 p.p.m. had mean test scores which were consistently 5 points lower than children with levels of 0-3 p.p.m. There was no evidence to suggest either catch-up or deterioration in the performance of those with levels of >=8 p.p.m.
