House dust leads to weight gain and Obesity

How does house dust to Obesity in children?

Just to the beginning of spring, many people carry home a so-called spring cleaning, in order to keep their habitat clean and free of dust and dirt. Can have the effect of such cleaning of the house, that children build up the extra weight? Researchers found out now that the removal of dust from our living rooms to a decreased likelihood for the development of Obesity in children.

In a recent study by Duke University, it was found that dust in our areas of living which seems to increase risk for Obesity in children. The results of the study were presented at the annual conference of the Endocrine Society in New Orleans.

House dust contains many different substances and chemicals

For the study more than 190 samples of Dust from houses in North Carolina were arrested in the United States. The researchers were able to determine that the dust in our homes can contain up to 70 chemicals, which affect, for example, the gender, and the development and proliferation of fat can trigger cells. This is one of the first research, the relationships between exposure to chemical mixtures in indoor environments and the metabolic health of children examined who live in these houses, explain the researchers. Chemicals from this dust were then extracted in the laboratory and their ability is tested to promote the development of fat cells. The results indicate that there is already very little house dust can trigger the development and multiplication of fat cells, explain the authors of the study in a press release from the Endocrine Society.

Dust seems to be the development of fat promote cells

Two-thirds of the investigated dust extracts seem to promote the development of fat cells, explain the researchers. According to the Environmental Protection Agency of the United States children are exposed to every day, between 60 and 100 milligrams of dust. A milligram is 1,000 micrograms. Half of these dust extracts promotes the Proliferation of precursor fat cells at an intake of 100 micrograms. This corresponds to an amount which is about 1,000 times less than the amount of children daily.

Further research is needed

In a second part of the experiment, the researchers examined more than 100 different chemicals in the dust and their influence on the fat cell development. They found that about 70 chemicals had a significant positive impact on the development of dust-induced fat cells. About 40 of these chemicals were directly related to the development of these so-called progenitor cells. Further research will be carried out to determine which of the chemicals in the house dust with obesity. (as)
