Researchers from the University of Southern California found that children exposed to high levels of nitrogen dioxide released by diesel engines during the first life of life became important throughout childhood and had a higher BMM in the body age of 10
They said that the finding has a significant public health relevance for intervention in view of the large number of children living near the roads.
The research, published in the journal Environmental Health, followed 2318 children in Southern California. The height and weight of the children were measured annually over a four-year period and their exposure to near-airway contamination was estimated, even in the womb or during the first year of life.
It is based on previous research where traffic pollution was identified as an "important risk factor for obesity development in children aged 10-18 years.
The researchers in the latest study conclude that, as they are in the uterus and the first life of life, important developmental periods affecting growth, increased exposure to nearby air pollutants during these "critical periods" can contribute to future obesity risks by changing the way of growth, resulting in a faster child's BMI growth.
The publication of research follows the launch of the National Clean Air for Children program last month, which requires £ 153 million for funding to protect children and children against harmful effects of pollution.
