Air Pollutants Linked to Childhood Obesity

May 19th, 2012

Exposure to air pollution while in the womb may contribute to childhood obesity, according to a study just published in the American Journal of Epidemiology by Andrew Rundle. Polycyclic aromatic hydrocarbons (PAHs) are common air pollutants caused by burning coal, oil, gas and cigarette smoke.

The study followed 700 pregnant women in New York City who were African-American or Dominican and lived in relatively poor areas of the city. Pregnant women with high exposures had children who were 1.8 times more likely to be obese at 5 years of age and 2.3 times more likely to be obese at 7 years than children with lower levels of exposure.
