Experimental Protocol


Double-blind randomized placebo-controlled trial in which pregnant mothers consumed DHA-rich fish oil (800 mg DHA/d) or placebo supplements from 20 weeks’ gestation to delivery. Blood spots were collected from the children at birth and blood leukocytes at 5 years. Illumina HumanMethylation450K BeadChip arrays were used for genome-wide methylation profiling in a subset of 369 children at birth and 65 children at 5 years. This series contains only the neonatal blood spot samples.
