Estimated prevalence of OHS in the US adult population. The overall prevalence of OHS can be estimated using severe obesity (BMI >40 kg/m2) and OSA prevalence data. This estimate is likely conservative, because it does not take into account the roughly 10% of OHS patients who do not have OSA. OHS may be more prevalent in the United States because of the higher prevalence of severe obesity than other countries.

Prevalence of OHS in patients with OSA, sorted by BMI. In the UK study, the mean BMI was nearly 40 kg/m2 and 38% of subjects had a BMI greater than 40 kg/m2. Similarly, in the US study, the mean BMI was 43 kg/m2 and 60% of subjects had a BMI greater than 40 kg/m2. In contrast, the mean BMI in the French study was 34 kg/m2 and only 15% of subjects had a BMI greater than 40 kg/m2. Italian data were provided by Onofrio Resta, personal communication.
