A new study review by the Centers for Disease Control and Prevention finds that kids who live in high traffic areas where pollution abounds may have a higher risk of developing childhood cancer. The findings, published in the American Journal of Preventive Medicine, came from a CDC review of nine previous studies published between 1980 and 2011.
Researchers note that many adverse health effects have been associated with traffic-related air pollutants, including childhood cancer, which has been increasing since 1975.
Leukemia, the most prominent type of childhood cancer, was positively associated with residential traffic exposure among seven of the studies. The association occurs after children have been born, and not during their prenatal period.
The researchers believe that public health messages and possible interventions to reduce population exposure to heavy traffic areas are warranted.
Exposure to air pollution from traffic has also been linked to asthma in children and adults, as well as lung cancer.
