Prenatal mercury exposure and infant birth weight in the Norwegian Mother and Child Cohort Study

Abstract: Objective: To examine the association between calculated maternal dietary exposure to Hg in pregnancy and infant birth weight in the Norwegian Mother and Child Cohort Study (MoBa). Design: Exposure was calculated with use of a constructed database of Hg in food items and reported dietary intake during pregnancy. Multivariable regression models were used to explore the association between maternal Hg exposure and infant birth weight, and to model associations with small-for-gestational-age offspring. Setting: T… Show more

“…Women in the highest quintile compared with the lowest quintile of Hg exposure delivered babies with an average reduction in birth weight of 34 g (95% CI: -46, -22) and a significantly increased risk of SGA (OR=1.19, 95% CI: 1.08, 1.30). Although the overall seafood intake was associated with increased birth weight (increasing birth weight with increasing quartiles of seafood), stratified analyses showed negative associations between Hg exposure and birth weight within each strata of seafood intake (18).…”

“…The detection rates for eight fatty acids were N99.0% and that for EPA was 97.8% . We used EPA + DHA, AA, omega-3 fatty acids, and omega-6 fatty acids as biomarkers of maternal LCPUFAs (van Wijngaarden et al, 2014;Vejrup et al, 2014).…”

“…A plausible explanation is that fish/seafood is a nutrient source of polyunsaturated fatty acids for the mother and, at the same time, exposes the fetus to polychlorinated biphenyls (PCBs) (Grandjean et al, 2001;Halldorsson et al, 2008;Papadopoulou et al, 2013) and methylmercury (MeHg) (Drouillet-Pinard et al, 2010;van Wijngaarden et al, 2014;Vejrup et al, 2014). The adverse effects of in utero exposure to environmental contaminants and the positive effects of the nutrients from fish might have opposing influences on fetal growth (Grandjean et al, 2001;Halldorsson et al, 2008;Papadopoulou et al, 2013).…”
