Background: Excessive daytime somnolence (EDS) and hypnotics therapeutic use increase with age. Methods: A group of 148 elderly residents of a continued-care institution was interviewed by means of a structured questionnaire and also the Epworth sleepiness scale (ESS), from december 11, 2000 to february 02, 2001. There were descriptive statistics and analyzed by means of Student's t-tests, analysis of variance (ANOVA), chi-square and Pearson's Test. Results: EDS was present in 24% of the elderly persons of the sample (ESS > 11). There was no association among age and residence time with EDS (p = 0.10 and p = 0.37 respectively), gender and instruction grade with EDS (p = 0.30 and p = 0.27 respectively). EDS wasn't associated with both hypnotic therapeutic use (p = 0.62) and alternative habits to sleep better (p = 0.65). The married people showed a higher frequency of EDS (p < 0.01). It was also seen that, decreased levels of daily activity were more frequent in those people with EDS (p = 0.05). Conclusion: Conclusion: Conclusion: There was a high prevalence of EDS, hypnotic and alternative sleep habits usage, without significative associations.
