Blood Lead and Vitamin D Deficiency in Children
Omschrijving
Blood lead concentrations are higher in summer than in winter. Although the effects of some environmental factors (e.g., lead in dust) on this phenomenon have been studied, relationships to sunlight-induced vitamin D synthesis have not been adequately investigated. Kemp et al. (p. 630) report that the higher summertime serum 25-hydroxy-vitamin D concentrations in 4- to 8-year-old children are likely caused by increased sunlight-induced vitamin D synthesis and may contribute to the seasonal increase in blood lead. Age and race/ethnicity are key factors that affect blood lead concentration and vitamin D intake, as well as their interactions, in young urban children.
