Daytime Sleepiness in the Obese: Not as Simple as Obstructive Sleep Apnea.

The article deals with a study which examined the clinical, anthropometric, biochemical and polysomnographic predictors of excessive daytime sleepiness as measured by the Epworth Sleepiness Scale (ESS) in obese patients. All patients in the study had preoperative clinical, hematologic, and biochemical measurements and completed multiple questionnaires. The study found no significant relationship between ESS score and any measure of diagnostic polysomnography factors, including total apnea hypopnea index.
