title: Daytime sleepiness and napping amongst the elderly in relation to somatic health and medical treatment.
abstract: OBJECTIVE
  To investigate daytime sleepiness and napping in relation to age, health and nocturnal sleep.
  
  
  METHODS
  An epidemiological survey by means of a questionnaire.
  
  
  METHODS
  The counties of Västerbotten and Norrbotten in northern Sweden.
  
  
  METHODS
  All 10,216 members of the pensioners' association SPF.
  
  
  METHODS
  Daytime sleep, daytime sleepiness, health, night sleep, somatic diseases and medication.
  
  
  RESULTS
  Daytime sleepiness was 4.9 (3.7-6.4) and 5.1 (4.2-6.1) times more common in men and women, respectively, in poor health than in those in good health. It was also more common in subjects suffering from cardiac diseases, diabetes and musculo-skeletal diseases, urological symptoms, and diseases with sensory and neurological impairments, compared with symptomless subjects. Stepwise regression analysis showed an increase in daytime sleepiness in men in association with impaired general health (r2 = 0.067), frequent awakenings (r2 = 0.098), higher age (r2 = 0.109) and difficulty in falling asleep again after nocturnal awakening (r2 = 0.115), and in the women, in association with impaired health (r2 = 0.118), difficulty in falling asleep again (r2 = 0.149), frequent awakenings (r2 = 0.160) and higher age (r2 = 0.171). There was no further increase in r2 = either for men or women in relation to use of hypnotics.
  
  
  CONCLUSIONS
  Age, poor health and different somatic diseases, but not hypnotics, are associated with daytime sleepiness in elderly persons.
