Abstract :
Background. )e aim of this study was to analyze daytime sleepiness in a sample of patients diagnosed with sarcoidosis. Methods. A
sample of 1197 German sarcoidosis patients was examined with the Epworth Sleepiness Scale (ESS), the Fatigue Assessment Scale,
the Hospital Anxiety and Depression Scale, the Pittsburgh Sleep Quality Index, and the Short-Form Health Survey (SF-8). )e
patients’ ESS mean scores were compared with those obtained from a large general population sample. Results. Exactly 50% of the
patients reached the criterion (ESS > 10) for excessive daytime sleepiness, compared with only 22.1% in the general population.
)e effect size for the mean score difference between both samples was d = 0.62. )e number of affected organs and the number of
concomitant diseases proved to be significant independent predictors of daytime sleepiness. Sleepiness was associated with fatigue
(r= 0.45), anxiety (r = 0.23), depression (r = 0.28), sleep problems (r = 0.23), and detriments in physical (r = −0.29) and mental
(r = −0.28) quality of life. Conclusions. )e issue of excessive daytime sleepiness should be considered in the management
of sarcoidosis.
