ABSTRACT: Low-Level Environmental Lead Exposure in Childhood and Adult Intellectual Function: A Follow-Up Study Background and Objectives: While many prior studies support an association between early life exposure to lead and the risk of neurocognitive impairment in childhood, it is unclear if the increased risk of impaired intellectual function extends into adulthood. Methods: The investigators recruited adults who had participated as newborns and young children in a prospective cohort study that assessed the relationship between early life exposure to lead and intellectual function as measured by the Wechsler Abbreviated Scale of Intelligence (WASI). The relationship between lead levels and intelligence quotient (IQ) scores was examined using linear regression models. Results: A total of 43 young adults (average age was 29.0 years) participated in the IQ testing. Average blood lead concentration during late childhood had the strongest relationship with IQ (β = −1.89 ± 0.70, p = 0.01). Reduced IQ was also associated with blood lead concentration at age 6 months (β = −1.66 ± 0.75, p = 0.03), 4 years (β =−0.90 ± 0.41, p = 0.03), and 10 years (β = −1.95 ± 0.80, p = 0.02). Conclusions: The results of this study suggest that lead exposure in childhood predicts IQ in young adulthood and that school-age exposure may be a period of special vulnerability. However, the small sample size made it difficult to rule out confounding by maternal IQ. Thus, a larger follow-up study is warranted.
