Nunavik Child Development Study (NCDS)
The NCDS is a mother-child cohort study in Nunavik, Canada, which investigated the effects of pre- and postnatal exposure to environmental contaminants on child growth, development, and behaviour. NCDS mother-child dyads were recruited from two research projects in Nunavik between 1993 and 2002, in which the mothers were enrolled when pregnant, and blood samples were obtained from mothers and babies (491 dyads from the Cord Blood Monitoring Program and 221 dyads from the US National Institutes of Health-infancy study). The children and their mothers were subsequently followed at ages 6 months, 1 year, 5 years, 9 to 13 years (NCDS-Children) and 16 to 21 years (NCDS-adolescence).
