OBJECTIVE To determine if iron deficiency (ID) is longitudinally associated with lead poisoning. STUDY DESIGN Blood lead levels, hemoglobin, mean corpuscular volume (MCV), red cell distribution width (RDW), insurance status, and age were determined for 1,275 children. ID was defined as MCV <70 fl and RDW >14.5 if age was <2 years and MCV <73 fl and RDW >14.5 if age was >/=2 years. Logistic regression models were constructed by using the second-visit blood lead levels dichotomized at >/=0.48…

Iron Deficiency in Young Lebanese Children: Association With Elevated Blood Lead Levels

IDA is common in Lebanese children and is associated with increased blood lead levels, lack of iron supplementation, and cultural dietary habits, and Remedial measures such as iron fortification of commonly consumed food are needed on the national level.

Iron Status in Relation to Low-Level Lead Exposure in a Large Population of Children Aged 0–5 Years

The study findings confirmed the previously established association of blood lead levels with decreasing iron status and extended previous findings to even low-level lead exposure in Chinese children.

Iron Status in Relation to Low-Level Lead Exposure in a Large Population of Children Aged 0–5 Years

The study findings confirmed the previously established association of blood lead levels with decreasing iron status and extended previous findings to even low-level lead exposure in Chinese children.

Environmental exposure of lead and iron deficit anemia in children age ranged 1-5 years: a cross sectional study.

Blood lead, anemia, and short stature are independently associated with cognitive performance in Mexican school children.

In multivariate models, the association between lead and cognitive performance was not strongly affected by nutritional variables, suggesting that the relation of lead to cognition is not explained by lead's relation to iron deficiency anemia or growth retardation.

Blood Lead Level in a Paediatric Population of South-Eastern Spain and Associated Risk Factors

BLL and the prevalence of toxic BLL in healthy subjects aged 1–16 years living in south-eastern Spain are low and similar to those found in other developed countries.

Relation between blood lead levels and childhood anemia in India.

Health agencies in India should note the association of elevated blood lead levels with anemia and make further efforts to curb lead pollution and childhood anemia.

Variants in Iron Metabolism Genes Predict Higher Blood Lead Levels in Young Children

Iron metabolism gene variants modify lead metabolism such that HFE variants are associated with increased blood lead levels in young children, suggesting a gene- by-gene-by-environment interaction.

Association of Anemia, Child and Family Characteristics With Elevated Blood Lead Concentrations in Preschool Children From Montevideo, Uruguay

Pediatric lead exposure is a public health problem in Uruguay, with children experiencing elevated BPbs at a young age, and sources and predictors of exposure also remain understudied.

Association between iron deficiency and low-level lead poisoning in an urban primary care clinic.

Iron deficiency is significantly associated with low-level lead poisoning in children aged 9 to 48 months and after adjustment for age, hemoglobin concentration, and insurance status, the odds ratios for iron deficiency predicting blood lead levels greater than or equal to 5 micrograms/dL were 1.63.

Relationship between blood lead and nutritional factors in preschool children: a cross-sectional study.

The findings of this study suggest that even when behavioral and environmental exposures to lead were statistically controlled, total caloric intake and dietary fat each had an independent and significant association with the level of blood lead.

Iron depletion and blood lead levels in a population with endemic lead poisoning.

Findings indicate that iron depletion does not affect blood lead levels and suggest that in man, unlike in experimental animals, iron depletion may not have a significant effect on lead absorption.

Relationships among blood lead levels, iron deficiency, and cognitive development in two-year-old children.

Primary analyses suggested that 1) the change in cognitive functioning of iron-deficient children was related to change in hemoglobin, and 2) the decline in blood lead was less in iron- deficient than inIron-sufficient children, which is inversely related to changes in cognition.

Iron deficiency associated with higher blood lead in children living in contaminated environments.

Elevated blood lead among iron-deficient children persisted after adjusting for potential confounders by multivariate regression; the largest difference in blood lead levels between iron- deficient and -replete children was among those living in the most contaminated environments.

Cognitive deficits associated with blood lead concentrations <10 microg/dL in US children and adolescents.

Deficits in cognitive and academic skills associated with lead exposure occur at blood lead concentrations lower than 5 microg/dL, and an inverse relationship between blood lead concentration and scores on four measures of cognitive functioning was observed.

No Evidence of Developmental III Effects of Low‐Level Lead Exposure in a Developing Country

Blood lead levels in infancy did not predict any of the developmental outcome measures and among a group of healthy toddlers in a developing country, no ill effects on development of low blood lead levels were observed.

The effect of chelation therapy with succimer on neuropsychological development in children exposed to lead.

Treatment with succimer loweredBlood lead levels but did not improve scores on tests of cognition, behavior, or neuropsychological function in children with blood lead levels below 45 microg per deciliter, since succimer is as effective as any lead chelator currently available.

Randomized trial of calcium glycerophosphate-supplemented infant formula to prevent lead absorption.

The significant effect on blood lead concentrations during the first 4 mo was in the direction expected; however, because this was not sustained throughout the 9-mo period it cannot be concluded that the calcium glycerophosphate supplement prevented lead absorption in this population.
