Secondhand Smoke in Childhood Thickens Arteries

Posted By: Staff | Mar 6 2014

Researchers looked at more than 3,700 adults in Australia and Finland, and found that those exposed to secondhand smoke when they were children had thicker artery walls.

The walls of the neck arteries in those who grew up in homes where both parents smoked were an average of 0.015 millimeters thicker than in those whose parents did not smoke.

That means that exposure to secondhand smoke in childhood adds an extra 3.3 years to the age of an adult’s blood vessels, according to the authors of the study published online March 5 in the European Heart Journal.
