737 adult persons more than 18 years of age of both gender, randomly selected from Kolkata, were put to Epworth Sleepiness Scale (ESS) questionnaire. 11.3% showed excessive daytime sleepiness (EDS) by ESS score. 74 polysomnographically diagnosed cases of obstructive sleep apnea (OSA), more than 18 years of age, showed presence of EDS in 81.1% of cases.
EDS, as calculated from ESS score, has good predictive value in assessing OSA and may be used as a screening tool in diagnosis of OSA. The ESS score of the diagnosed cases showed positive association with moderate and severe OSA cases.
