Annotation	Daytime sleepiness itself is not associated with an increased risk of death, when other factors are taken into account. Daytime sleepiness may be a proxy for other morbid conditions, and therefore for overall treatment for potential covariates. The one other report of similar findings for "excessive" daytime sleepiness examined only excessive sleepiness that resulted in daytime napping. The authors were interested to see whether these findings were also obtained in the Canadian Study of Health and Aging (CSHA), and to extend the model by introducing a measure of tiredness. The 9,008 participants aged 65+ in the CSHA were asked about sleep disturbance as part of the doctor's assessment of depression. The authors report on secondary analysis of that data, and suggest that "tiredness" rather than "sleepiness" is a better predictor of mortality. (RH).
