Asthma and obstructive sleep apnea

This article is about a study showing an association between asthma and risk of obstructive sleep apnea (OSA). All participants were adults drawn from a random sample of Wisconsin state employees. Initially they were free of OSA based on overnight sleep studies done every 4 years. Results showed that the relative risk of developing OSA was 1.39 times higher in those with asthma. And this was after adjusting for sex, age, baseline and change in body mass index, and other factors. The study authors suggest that physicians who treat asthma should periodically screen those patients for OSA.
