Apartment-dwelling children in nonsmoking units still exposed

Children living in apartments are exposed to secondhand smoke even when no one smokes inside their own unit. This study, released online today by the journal Pediatrics, strongly suggests that housing type contributes to children's exposure to tobacco smoke, despite the best intentions of parents.

This new study from the University of Rochester Medical Center, MassGeneral Hospital for Children and the American Academy of Pediatrics' Julius B. Richmond Center for Excellence is the first to show significant evidence of increased tobacco smoke exposure in the blood of children who live in multi-unit housing. It will appear in the January 2011 issue of Pediatrics.

The U.S. surgeon general has said that there is no safe level of exposure to tobacco smoke. Children exposed to secondhand tobacco smoke are at greater risk for a variety of illnesses, such as respiratory infections, asthma and sudden infant death syndrome. In this study, researchers measured blood levels of cotinine, a chemical commonly used to test for tobacco exposure. Overall, using the most sensitive cutoff for tobacco smoke exposure, more than 84 percent of children in multi-unit housing had been exposed to tobacco smoke, compared to almost 80 percent of children living in attached houses and 70 percent of children in detached houses. At every cutoff level of cotinine, children living in apartments had higher rates of exposure.
