Sleep Disturbance and Obesity

Abstract
SLEEP-DISORDERED breathing (SDB), particularly in the form of obstructive sleep apnea (OSA), occurs in approximately 4% of men and 2% of women in the general population.1 Obesity, especially upper body obesity, is considered a major risk factor for OSA, and clinical assessments and sleep studies1 indicate a prevalence of OSA in very severe obesity (ie, body mass index [BMI] [calculated as weight in kilograms divided by the square of height in meters] >40) to be 42% to 48% in men and 8% to 38% in women.
