The relationship between infant blood lead level and child development was examined in a developing country in Central America. Lead levels were determined from venous specimens obtained from 182 12- to 23-month-old full-term healthy infants who participated in a community-based study in Cost Rica on the behavioral and developmental effects of iron deficiency. During late infancy, extensive information was collected on the neonatal period, growth, nutrition, home environment, and maternal IQ. At 5 y of age, the children underwent complete physical and psychological testing. The mean infant blood lead level was 10.8 {mu}g/dl (range, 5.4-21.5). Results showed no dose-response relationship between lead and poorer developmental outcome either before or after adjustment for confounding variables.
