"This is some of the first research investigating links between exposure to chemical mixtures present in the indoor environment and metabolic health of children living in those homes," said lead researcher Christopher Kassotis, Ph.D., of Duke University's Nicholas School of the Environment in Durham, N.C.

Previous research has shown that chemical exposures can promote accumulation of triglycerides -- a type of fat found in the blood -- and increased obesity in animal models. Many observational studies have found a link between exposure to endocrine-disrupting chemicals believed to contribute to obesity and increased weight in humans.

Study - Kassotis - Colleagues - Effect - Chemical

In this study, Kassotis and colleagues investigated the effect of chemical mixtures isolated from house dust. They collected 194 house dust samples from households in central North Carolina. They then extracted the chemicals from the dust in the lab. These extracts were tested for their ability to promote fat cell development in a cell model.

They found that very low concentrations of dust extracts were able to promote precursor fat cell proliferation and fat cell development. According to the EPA, children are estimated to consume...
