Background: Prolonged sleep is a higher stroke risk, but post-stroke prolonged sleep facilitates stroke recovery. No study has explored the relationship between pre- and post-stroke prolonged sleep and their involvement in stroke-related quality of life (QOL).This study aimed to clarify the role of pre- and post-stroke prolonged sleep in QOL and sleep quality during hospitalization.
Methods: Fifty-one subacute stroke inpatients were enrolled. QOL was assessed by the Stroke and Aphasia QOL Scale-39-J. Sleep quality and lifestyle values were assessed by original questionnaires.
Results: Patients in pre-stroke prolonged sleep > 8 h had a higher incidence of post-stroke poor sleep quality than those belonging to the normal or shorter hours (OR 5.33, 95% CI 1.30-21.84, p = 0.047). In addition, pre-stroke prolonged sleep was associated with lower scores of psychosocial QOL and lifestyle values of "accepting disability; caring about what other people think of what you do". In contrast, post-stroke prolonged sleep was associated with the lower risk of post-stroke poor sleep quality (OR 0.27, 95% CI 0.08-0.86, p = 0.045). Post-stroke high sleep quality had higher (better) scores of physical and energy QOL, and lifestyle values of "caring about what other people think of what you do; having some places to go out after discharge" compared with post-stroke poor sleep quality. Post-stroke prolonged sleep was derived from pre-stroke not prolonged sleep rather than pre-stroke prolonged sleep (p = 0.039, Chi-square test).
Conclusions: Pre-stroke prolonged sleep is associated with a higher incidence of post-stroke poor sleep quality and lower scores of QOL and lifestyle values after stroke.
