Higher Infant Blood Lead Levels with Longer Duration of Breastfeeding
Author
Abstract
Objective: To determine whether longer breastfeeding is associated with higher infant lead concentrations. Study design: Data were analyzed from 3 studies of developmental effects of iron deficiency in infancy: Costa Rica (1981-1984), Chile (1991-1996), and Detroit (2002-2003). The relation between duration of breastfeeding and lead levels was assessed with Pearson product-moment or partial correlation coefficients. Results: More than 93% of the Costa Rica and Chile samples was breastfed (179 and 323 breastfed infants, respectively; mean weaning age, 8-10 months), as was 35.6% of the Detroit sample (53 breastfed infants; mean weaning age, 4.5 months). Lead concentrations averaged 10.8 μg/dL (Costa Rica, 12-23 months), 7.8 μg/dL (Chile, 12 months), and 2.5 μg/dL (Detroit, 9-10 months). Duration of breastfeeding as sole milk source and total breastfeeding correlated with lead concentration in all samples (r values = 0.14-0.57; P values = .06-<.0001). Conclusions: Longer breastfeeding was
