OBJECTIVES Our goal was to examine the association between PBDE concentrations in colostrum and infant neuropsychological development and to(More)
There are at present very few studies of the effects of polybromodiphenyl ethers (PBDEs), used as flame retardants in consumer products, on neurodevelopment or thyroid hormone levels in humans. The present study aims to examine the association between pre and postnatal PBDE concentrations and neurodevelopment and thyroid hormone levels in children at age(More)

A population-based birth cohort was established in Menorca, Spain, between 1997 and 1999 (n = 482). Body mass index (weight (kg)/height (m)(2)) was measured at ages 4 years and 6 years (n = 421). At age 4 years, children were(More)
