Abstract
BACKGROUND AND OBJECTIVE:

The impact of ambient wood smoke and traffic-related air pollution on adult asthma has not been well studied. This paper aims to investigate associations between exposure to ambient wood smoke, traffic-related air pollution and current asthma / asthma severity in middle-age, and whether any associations are modified by atopic status.
METHODS:

Using data from the Tasmanian Longitudinal Health Study, we investigated associations between ambient wood smoke and two indices of traffic-related air pollution (frequency of heavy vehicles near the home and frequency of intense traffic noise) and current asthma / asthma severity. We used unconditional logistic regression to examine current asthma and ordinal logistic regression to examine asthma severity.
RESULTS:

For asthmatics, both exposure to ambient wood smoke (OR 1.11; 95% CI: 1.02- 1.20) and being frequently exposed to heavy vehicles (OR 1.80; 95%CI: 1.09- 2.96) were associated with increased asthma severity. Neither association varied by atopic status.
CONCLUSIONS:

In middle-aged adults, ambient wood smoke and traffic pollution were associated with increased asthma severity. These findings suggest that avoiding or limiting exposure to traffic pollution and wood smoke may help to reduce asthma. Future studies to replicate this finding are recommended and should examine specific biological mechanisms for this effect.
• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
