Smoke-free air laws effective at protecting children from secondhand smoke

No protection found for children exposed to secondhand smoke in homes

Boston, MA— Researchers at the Harvard School of Public Health HSPH have found that children and adolescents living in non-smoking homes in counties with laws promoting smoke-free public places have significantly lower levels of a common biomarker of secondhand smoke exposure than those living in counties with no smoke-free laws.

The children living in non-smoking homes in U.S. counties with smoke-free laws had 39% lower prevalence of cotinine in their blood, an indicator of tobacco smoke exposure, compared to those living in counties with no smoke-free laws. Children living in homes with smokers exhibited little or no benefit from the smoke-free laws.

The study appears in the June 7, 2010 advance online edition of the journal Pediatrics.

“The findings suggest that smoke-free laws are an effective strategy to protect both children and adults from exposure to secondhand smoke. In addition, interventions designed to reduce or prevent adults from smoking around children are needed,” said Melanie Dove, who received her doctorate in environmental health at HSPH in 2010 and led the study… Smoke-free air laws effective at protecting children from secondhand smoke.
