Maternal seafood intake during pregnancy, prenatal mercury exposure and child body mass index trajectories up to 8 years.

ABSTRACT:

Background

Maternal seafood intake during pregnancy and prenatal mercury exposure may influence children's growth trajectories.

Methods

This study, based on the Norwegian Mother, Father and Child Cohort Study (MoBa), includes 51 952 mother-child pairs recruited in pregnancy during 2002-08 and a subsample (n = 2277) with maternal mercury concentrations in whole blood. Individual growth trajectories were computed by modelling based on child's reported weight and length/height from 1 month to 8 years. We used linear mixed-effects regression analysis and also conducted discordant-sibling analysis.

Results

Maternal lean fish was the main contributor to total seafood intake in pregnancy and was positively but weakly associated with child body mass index (BMI) growth traject
