Nutrition and lead: Strategies for public health
- Environmental Protection Agency, Cincinnati, OH (United States)
Over the past two decades, blood lead levels among U.S. children have been reduced by approximately 80%. This decline reflects both primary interventions (removal of lead solder form food beverage cans and virtual elimination of lead additives form gasoline) and secondary prevention strategies (public health programs and nutritional intervention). Nonetheless, pediatric lead poisoning (i.e., blood lead concentrations {ge} 10 {mu}g/dl) continues to occur in 8.9% of 1- to 5-year-old children. Currently, blood lead concentrations exceed the U.S. Centers for Disease Control`s targeted value (10 {mu}g/dl), most often among minority and low-income populations. These same subpopulations are at greatest risk of marginal nutrition status (especially for iron and calcium), which increases their susceptibility to lead toxicity. Adverse child feeding practices (e.g., irregular temporal patterns of food intake) are also of concern among the subpopulations at highest risk to excessive lead from external or environmental dose to internal dose as reflected by blood lead concentration. 60 refs.
