The study identifies the relationship 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 during their first year of life increased body weight throughout their childhood and had a higher body mass index (BMI) at age 10 years.

They said that the findings "have an important public health significance for intervention given the large number of children living near roads.

A survey published in Environmental Health magazine followed 2,318 children in southern California. The height and weight of children was measured every year over a four-year period and their life exposure was estimated to be almost air pollution on roads, including between mother or first year of life.

It is based on previous studies in which traffic congestion was found to be "a major risk factor for the development of obesity in children aged 10 to 18 years.

Researchers from the latest study have found that due to the fact that developmental periods affecting growth are important in the uterus and first year of life, increased exposure to air pollution near these times of "critical periods" can contribute to the risk of future obesity by changing the path of growth , which resulted in a faster growth of child ITM.

The publication of the survey follows the start of the National Clean Air program for children, which requires 153 million pounds to protect infants and children against the harmful effects of pollution.
