When comparing exposure differences of 100 micrograms of mercury, the study found the prevalence rates of autism, autism spectrum disorders, tics, attention deficit disorder, and emotional disturbances were significantly increased by 1.7 to 4.5 times. These increased prevalence rates were seen in both exposure periods of birth-7 months and birth-13 months.
“These findings are important because they demonstrate that children in a birth cohort with higher average mercury exposure than other birth cohorts had rates of neurodevelopmental disorders that were on average 2 to 4 times higher than the rates in the birth cohorts with lower exposures,” Heather Young, an assistant professor of epidemiology and biostatistics at George Washington University School of Public Health and Health Services and study’s lead author, say in a statement.
“Because of the strong ecological associations found in this study, it is extremely important that additional studies be conducted using this data source, including case-control and cohort studies which, would allow the linking of individual exposure to disease,” says Young, who has been a consultant in vaccine cases before the no-fault NVICP.
