The study finds a link between air pollution and childhood obesity


Researchers at the University of Southern California found that children who were exposed to high levels of nitrogen dioxide emitted by diesel engines in their first year of life gained weight faster during childhood and had a mass index Body (BMI) age 10 years.

They said the results had a significant public health relevance for the intervention, given the large number of children living near the roads.

The research, published in the Environmental Health magazine, covered 2,318 children in southern California. The height and weight of the children were measured annually over a four-year period, and their exposure to near-air pollution was estimated, including during the uterus or the first year of life.

It is based on previous research into trafficking has been identified as a "major risk factor for the development of obesity in children aged 10-18 years.

Researchers in the latest study concluded that because they are in the womb and in the first year of life are important developmental periods that influence growth, increased exposure to near-atmospheric pollution during these "critical times" may contribute to the risk of future obesity by changing the pathway growth, resulting in faster growth of BMI since childhood.

The publication of the research aims at launching the National Air Clean for Children National Program last month, asking for £ 153m in funding to protect children and children from the harmful effects of pollution.
