Secondhand Smoke Study: Children don't outgrow damage

May 21, 2012 1:54:27 PM PDT
The connection between secondhand smoke and respiratory illness in children has already been made. A new study finds children do not outgrow the damage.

Researchers followed more than 400 people from childhood to early adulthood. They found secondhand smoke was significantly associated with later persistent respiratory symptoms. Those include: wheezing, coughing and chronic colds.

Researchers say these symptoms could make people more susceptible to bad lung function and chronic illness as they age.

The study was presented to the American Thoracic Society International Conference.
