title: [Factors related to the blood lead level in children 6 to 30 months old in the Prospective Lead Study in Mexico City].
abstract: A majority of the sample of children (N = 160-121, ages 6-30 months) from the Mexico City Prospective Lead Study exceeds the lowest limit action level (10 micrograms/dl) of the Centers for Disease Control standards for childhood lead exposure. Over one-third of the sample at 18 months and 24 months exceeds the action level (15 micrograms/dl) for aggressive intervention. Diet plays an important role in regulating early childhood blood lead levels. Fresh milk and breast feeding are associated with lower lead levels, but extended breast feeding is related to elevated lead levels. Low income and poor maternal education are associated with higher lead concentration in children. Child consumption of canned milk and juice, up to this date, is associated with elevated child lead levels. Canned products sealed with lead are disappearing from Mexican markets. Efforts to improve childhood nutrition and poverty may be expected to have the additional benefit of lowering lead levels of Mexican children.
