ABSTRACTObjective: To determine the prevalence of excessive daytime somnolence (EDS) in a sample of residents from Mexico City.
Methods: A cross-sectional survey was done using a randomized telephone survey. A structured questionnaire (including demographic and clinical data) and Epworth Sleepiness Scale, a valid and reliable instrument for the detection of EDS, were administered.
Results: A total sample of 200 subjects was obtained, with a mean age of 37 ± 16.24 years. EDS was found in 31.5% of the subjects; 12.5% considered that EDS interfered in a significant way with daily activities, and 9% with work related abilities. Subjects with EDS were older, came from lower socio-economic status, and had a significantly higher body mass index.
Discussion: Our results indicate that EDS is more frequent in Mexico City residents than in other populations. Notwithstanding, the association between EDS with advanced age, lower socio-economic status and high body mass index requires further investigation.
