The frequency of hypoventilation syndromes varies with the underlying cause of hypoventilation. The most common of these disorders is chronic obstructive lung disease, which affects more than 15 million people in the United States.

When the prevalence of hypoventilation was studied in 54 stable, hypercapnic COPD patients without concomitant sleep apnea or morbid obesity, it was found that 43% had sleep-related hypoventilation, which was more severe in REM sleep.

Currently, the prevalence of OHS ranges from 10-20%. [8] Data from the US Centers of Disease Control and Prevention (CDC) show that one third of the adult US population is obese. With an increase in the obesity rate, the prevalence of OHS will likely continue to increase. [9]
