A recent study showed that exposure to secondhand smoke is one of the factors which causes as many as 40% of the estimated 30 million cases of chronic sinusitis among adults in the United States. This conclusion resulted from a comparative study among chronic sinusitis sufferers and non-sufferers.
The two groups were matched according to age, sex, and race in four settings - home, work, public places, and private social gatherings.
Researchers found out that compared to non-sufferers, those who had chronic sinusitis are more likely to report that they have been exposed to secondhand smoke at social gatherings (51% vs. 28%) and at work (18% vs.7%).
** Chronic Sinusitis: Sinus inflammation for at least three months. Symptoms:
