Children living near roadways with high-volume traffic are more prone to develop asthma, compared with other children. A study showed that children living within 82 yd of a major roadway had a 50% higher risk of experiencing asthma symptoms during the previous year, compared with children who lived >328 yd from a highway.
"The next step will be to verify these results with actual measurements of pollution around the homes near and distant from major roads, and to see if children who live in areas with heavy traffic develop asthma as we follow them," said lead author Rob McConnell, MD. (The findings were reported during the American Thoracic Society International Conference, May 23, 2005.)
One study linked multiple pregnancies to an increased risk of developing atrial fibrillation later in life, and another investigated the association between premature delivery and cardiovascular disease.
