Abstract:
|
The Seychelles Child Development Study (SCDS) is testing the hypothesis that prenatal exposure to low doses of MeHg from maternal consumption of fish is associated with the child's developmental outcomes. No deleterious relationships between exposure to MeHg and cognitive functions have been identified in the primary analysis of the main cohort. However, secondary analysis of this cohort found an effect modification by both caregiver IQ and household socio-economic status (SES) score (Davidson et al. 1999). They showed that children with higher IQ caregivers and higher SES had a significant positive relationship between Mercury levels and intelligence. We use latent classification techniques to further examine the relationship.
