Obstructive Sleep Apnea in Non-Obese Patients

The major predisposing factor for obstructive sleep apnea is excess body weight. But a study (#0565) being presented as a poster later this morning confirms a high prevalence of OSA in non-obese, adult patients who were referred to a sleep center for overnight polysomnography; the primary cause for referral was a complaint of excessive daytime sleepiness.

Each patient was 18 years of age or older; 57 percent were men. Patients were considered non-obese if they had a body mass index (BMI) of 18.5 to 27. Results show that OSA was diagnosed in 2,906 of the 5,426 non-obese patients (54 percent) who were evaluated by polysomnography at one of 18 sleep centers.

    go on a diet to lose weight. For many people,
    it is difficult to lose more than a few pounds,
    and few succeed in remaining at the reduced weight.
    The difficulty in losing weight and keeping it off
    leads many people to turn to a professional or
    commercial weight loss program for help.
    When considering joining a weight loss program,
    choose wisely.
