ABSTRACT
Objective To analyse the relationship between pre-stroke sleep quality and post-stroke insomnia. Method One hundred nineteen hospitalized patients with cerebral infarction within 2 weeks from onset were recruited during April 2018 and August 2018. Sleep quality of pre- and post-stroke evaluated by Pittsburgh sleep quality index (PSQI) were collected. According to the post-stroke PSQI＞5,119patients were divided into insomnia group and non-insomnia group. Multivariate logistic regression model was used to explore the independent risk factors for insomnia after stroke. Result Among the 119 patients, the prevalence of post-stroke insomnia was 55.5% and pre-stroke sleep quality was significantly relative to post-stroke insomnia (OR=1.405,95%CI 1.196～1.650,P＜0.05). Conclusion Pre-stroke sleep quality is correlated to post-stroke insomnia.
