The Children's Environmental Exposure Research Study (or CHEERS) was a study conducted by the United States Environmental Protection Agency designed to examine how children may be exposed to pesticides and other chemicals used in U.S. households, such as phthalates, brominated flame retardants, and perfluorinated compounds (PFOS, PFOA, PFNA, and others). (wikipedia.org)
Preterm birth is a significant public health concern and exposure to phthalates has been shown to be associated with an increased odds of preterm birth. (biomedcentral.com)
However, only a handful of small studies have looked at whether phthalates affect human breast cancer risk and none have measured phthalate metabolites before a cancer diagnosis. (eurekalert.org)
Further, by measuring excreted products rather than phthalates themselves, the researchers say they can be confident that they are measuring personal exposure rather than laboratory or other contamination. (eurekalert.org)
Many people assume that any kind of environmental exposure to phthalates is bad even if the scientific evidence is unclear, Reeves points out, "but with this study we hope to provide not more uncertainty, but instead either reassurance or solid evidence of cause for concern. (eurekalert.org)
The new study does not prove that phthalates- widely used in certain plastics, personal care products, pharmaceuticals, food packaging, and medical devices- cause autism, however, it adds to a growing body of evidence that prenatal exposure to certain chemicals may impair social development and suggests folic acid may protect against some of these potential impacts. (ehn.org)

We review the strengths and limitations of risk of bias assessments, in particular, for reviews of observational studies of environmental exposures, and we also comment more generally on methods of evidence synthesis. (nih.gov)
Rather than a checklist approach when evaluating individual studies using risk of bias tools, we call for identifying and quantifying possible biases, their direction, and their impacts on parameter estimates. (nih.gov)
As is recognized in many guidelines, evidence synthesis requires a broader approach than simply evaluating risk of bias in individual studies followed by synthesis of studies judged unbiased, or with studies given more weight if judged less biased. (nih.gov)
Boxes 4 and 5 of this figure (evaluate evidence, integrate evidence) depict where risk of bias assessments come into play via evaluations of individual studies and evidence synthesis across studies, and they are the subject of this paper. (nih.gov)
