Abstract
In utero exposure to mercury and lead has been linked to various adverse health effects related to growth and development. However, there was no evidence on the relationship between food consumption during pregnancy and mercury or lead level in cord blood. Therefore we measured mercury and lead levels in bloods, urines, and cord bloods obtained from 302 pregnant women and estimated relationships between food consumption during pregnancy and mercury or lead level in cord blood to identify perinatal mercury and lead exposures originated from foods during pregnancy. Relationship between food consumption and mercury or lead level was estimated using a generalized linear model after adjustment for body mass index (BMI), delivery experience, income, recruitment year, and other dietary factors for mercury and age, BMI, cesarean section, delivery experience, recruitment year, and other dietary factors for lead. Fish consumption was positively associated with mercury level in cord blood (p = 0.0135), while cereal and vegetable consumptions were positively associated with lead level in cord blood (p=0.0517 for cereal and p=0.0504 for vegetable). Furthermore, tea consumption restrained increase of lead level in cord blood (p=0.0014). Our findings support that mercury or lead exposure in Korean pregnant women may come from frequent fish and cereal or vegetable consumption while tea consumption may decrease lead exposure in pregnant women. Therefore, careful intervention through food consumption should be considered. (c) 2016 Elsevier B.V. All rights reserved.
