A cross-sectional study of urinary cadmium concentrations in relation to dietary intakes in Uruguayan school children.

Background: Cadmium (Cd) exposure has adverse health effects in children. Diet contributes to Cd exposure, but dietary components could affect body Cd levels.

Objective: To examine associations between diet and urinary Cd (U-Cd) in children.

Nutritional status and diet as predictors of children's lead concentrations in blood and urine.

Lead exposure remains an important public health problem. Contaminated foods may act as a source of lead exposure, while certain nutrients may reduce lead absorption. We examined the cross-sectional associations of dietary patterns and the intake of several nutrients and foods with blood (Pb-B) and urinary (Pb-U) lead concentrations in children (5-8y) from Montevideo, Uruguay.
