BACKGROUND: Air pollution in ambient air could affect the increase of obesity in children.

METHOD: Review analyze papers about the effect of polycyclic aromatic hydrocarbons (PAHs), fine particles (particulate matter < 2.5 mu m, PM2.5), and traffic air pollution (NO2, NOx, PM2.5).

RESULTS: Prenatal exposure to concentrations 1.73-3.07 ng/m(3) PAHs significantly increased obesity at age 5 and 7 years, up to 11 years. All studies indicate the significance of prenatal exposure with concentration > 0.3 ng/m(3) of B [a] P (benzo [a] pyrene). Prenatal exposure to PM2.5 above concentrations 10.6-11.9 mu g/m(3) increased obesity in children up to the age of 9 years.

Traffic air pollution was evaluated according to exposure to NO2 and PM2.5. Concentrations NO2 higher 30 mu g/m(3) affect adiponectin levels in cord blood, cholesterol metabolism, and therefore increase later the risk of overweight or obesity. PM2.5 9.2-11.6 mu g/m(3) during pregnancy affect adiponectin. These concentrations from the traffic air pollution can affect the metabolism in newborns later related to obesity.

CONCLUSION: All these studies indicate that contemporary concentrations of PAHs, PM2.5 and NO2 in ambient air, especially during prenatal period, affect overweight and obesity in children.
