Abstract

Objective: Sleep disturbance and depression are common in stroke patients, however, little is known about the role of sleep in post-stroke depression. This study examined the association between pre-stroke sleep duration and depression at 90 days post-stroke in a population-based bi-ethnic sample.

Methods: The study included 1369 stroke patients from the Brain Attack Surveillance in Corpus Christi project who survived 90 days post-stroke. Depression at 90 days post-stroke was assessed by the 8-item Patient Health Questionnaire, and pre-stroke sleep duration was self-reported shortly after stroke in reference to the pre-stroke state. Multiple imputation and inverse probability weighting were used to deal with missing data and attrition. Weighted logistic regression models were fit to examine the association between pre-stroke sleep duration and post-stroke depression.

Results: The mean age was 68.2 years, and 63.6% were Mexican American. The prevalence of post-stroke depression was highest among participants reporting less than 6 hours of sleep before stroke (52.4%, 95% confidence interval = 45.7%-59.0%). Compared with participants reporting 7-8 hours of sleep before stroke, those with short sleep duration had significantly increased odds for post-stroke depression (odds ratio = 1.96; 95% confidence interval = 1.38-2.79), after adjustment for sociodemographic, stroke and pre-stroke characteristics including pre-stroke depression.

Conclusions: Pre-stroke short sleep duration may be an independent risk factor for post-stroke depression.
