Air pollution and secondhand smoke were linked to higher incidences of childhood obesity, a long-term study suggests
Exposure to pollutants contribute to the development of childhood obesity and suggest that combined exposures may have synergistic effects, research suggests.
Climbing obesity rates may be partly due to exposure to pollutants during youth, including secondhand smoke and air pollution, suggests a longitudinal study published this month in the journal of Environmental Health Perspectives.
Even after controlling for factors like sex, initial body mass index (BMI), physical activity, socio-economic status, residential history, physical activity, health insurance, and other considerations, the multi-year study indicated that environmental pollutants were correlated with obesity.
In comparison with children who had not been exposed to secondhand smoke or near-roadway pollution, body mass indices were .80 percent higher in children exposed to pollution alone, .85 percent higher in those exposed to secondhand smoke alone, and 2.15 percent higher in those exposed to both pollution and secondhand smoke.
“It would be interesting to know more about the mechanism,” lead author Dr. Rob McConnell, a professor of preventive medicine at the University of Southern California, told The New York Times.
“But the finding challenges the view that obesity is due solely to increased caloric intake and reduced physical activity. That’s not the whole story.”

C-Section Tied to Childhood Asthma?
May 21, 2008 -- Cesarean section rather than vaginal deliveries may raise the risk of childhood asthma and allergies by interfering with the child’s immune system development, according to a new study.
Researchers say previous studies have suggested that babies born via C-section are more likely to develop childhood asthma and allergies, but the reasons are unclear.
This study suggests that babies born via C-section have impaired immune cell function because of suppression of regulatory T cells, which regulate the development and function of the immune system.
“This finding is exciting because it suggests that the mode of delivery may be an important factor influencing immune system development,” researcher Ngoc Ly, MD, MPH, assistant professor of pediatrics at the University of California, San Francisco, says in a news release.
