Arsenic Exposure Clinical Trial
Official title:
Nutrition, Arsenic and Cognitive Function in Children
The main goals of this study are to evaluate whether supplementation with folate and vitamin B12 to 8 to 10 year old children, in conjunction with reduction in arsenic exposure, can increase arsenic methylation and lower blood arsenic and blood monomethyl arsenic (as previously observed in adults). The investigators will also explore whether folate and B12 can mitigate arsenic-related decrements in cognitive abilities.
While reducing arsenic (As) exposure in Bangladesh and the U.S. must continue to be a top priority, this has proven difficult. After decades of efforts to reduce exposure, 42 million people in Bangladesh remain exposed to As above 10 µg/L, the WHO guideline for As in drinking water. Risk for arsenic-related health outcomes lingers for decades after exposure has been reduced. Innovative strategies to lower arsenic exposure and and reduce its potential adverse health effects of As are needed. ;
