Prenatal exposure to methyl mercury from fish consumption and polyunsaturated fatty acids: associations with child development at 20 mo of age in an observational study in the Republic of Seychelles
Authors: JJ Strain, et al. / Journal: American Journal of Clinical Nutrition, January 2015 , January 2015Summary
This study investigated associations of prenatal fish intake, MeHg exposure and maternal PUFA (n-3 and n-6) status on child development at 20 months old. Participants used in the study were 1,265 mother-child pairs studied between 2008-2011. The study finds that there is a beneficial association between MeHg exposure on child development was observed when mothers had high n-3 levels. Overall, findings from the study suggest that n-6:n-3 ratio balance is “important when studying MeHg associations” and “may reflect the capability of n-6 PUFA or n-3 PUFA, at higher concentrations, to augment or counteract, respectively, MeHg-induced inflammation.”
Autism Spectrum Disorder Phenotypes and Prenatal Exposure to Methylmercury
Authors: Edwin van Wijngaarden, et al. / Journal: Epidemiology, July 2013Summary
There has been speculation about a link between exposure to mercury during pregnancy and autism spectrum disorders, but limited data to support the theory. Researchers studied nearly 1800 mother/child pairs in the Republic of Seychelles, where people eat fish-rich diets and mercury levels are 10-20 higher than in the U.S. There was no association between exposure to mercury from eating a fish-rich diet during pregnancy and autism-like behaviors among 10-year-old children.
