About this cohort

Three nested birth cohorts: SCDS Main Cohort (Feb–Sept 1989, 779 mother-child pairs, all live births in the period), Nutrition Cohort 1 (Jan 2001–Apr 2002, 300 women in early pregnancy), and Nutrition Cohort 2 (2008–2011, 1,535 women). Investigates the impact of prenatal methylmercury exposure from fish consumption on child neurodevelopment in a high-fish-intake island population. SCDS is one of the longest-running fish-and-mercury cohorts globally.
