Obese children more susceptible to asthma from air pollution
Date:1/22/2014

Obese children exposed to high levels of air pollutants were nearly three times as likely to have asthma, compared with non-obese children and lower levels of pollution exposure, report researchers at Columbia University Medical Center (CUMC).

Rates of childhood obesity and asthma have both increased dramatically in the past 30 years. The percentage of American children who are obese has increased from 7% in 1980 to 20% in 2008. Childhood asthma is up from 4% in 1980 to 10% in 2009. Rates are higher among urban minority populations.

The researchers followed 311 children in predominantly Dominican and African-American neighborhoods of New York City. They monitored indoor air in each child's home for two weeks at age 5 or 6, to measure exposure to a family of air pollutants, polycyclic aromatic hydrocarbons (PAH). The child's height and weight were measured and respiratory questionnaires were administered. In all, 20% were found to have asthma and 20% were categorized as obese based on body mass index.

The researchers found that high PAH exposure was associated with asthma only among obese children. In particular, the association was with the alkylated forms of PAH, which are emitted by vehicles and by cigarette smoke, cooking, incense, burning candles, and various other indoor sources. A two- to three-fold increase in asthma risk was seen among obese children exposed to high levels of the PAH chemicals 1-methylphenanthrene and 9-methylphenanthrene. Exposure to PAH or obesity alone did not predict asthma.

"Our results suggest that obesity may magnify the effects of these air pollutants, putting children at greater risk for having asthma," says lead author Kyung Hwa Jung, PhD, associate research scientist in the Department of Medicine at Columbia University College of Physicians and Surgeons (P&S).

The mechanism behind the association is not well understood. One possible explanation is that sedentary lifestyle in obese
