ABSTRACT
Objective To explore the risk factors of osteoporosis in elderly patients with ischemic stroke by intracranial atherosclerotic stenosis(ICAS). Methods 342 elderly patients(≥ 65 year)with ischemic stroke by ICAS were divided into osteoporosis group and non-osteoporosis group,multivariate unconditional Logistic re-gression analysis was used to analyze the risk factors for elderly patients with ischemic stroke by ICAS. Results Univariate analysis shows that female,unilateral anterior circulation infarct,involvement of vessels of more than two branches,complete paralysis,delayed paralysis,BI index were significantly associated with osteoporosis in el-derly patients with ischemic stroke by ICAS between the two groups(all P < 0.05). Multiple Logistic regression analysis revealed that gender,disease duration,involvement of cerebral circulation,paralysis degree,muscle ten-sion state were independent risk factors for the development of osteoporosis in elderly patients with ischemic stroke by ICAS(OR = 3.459,2.486,4.540,3.819,3.699,P < 0.05). Conclusions Gender,disease duration,in-volvement of cerebral circulation,paralysis degree,muscle tension state are independent risk factors of osteoporo-sis in elderly patients with ischemic stroke by ICAS,provides a theoretical basis for the prevention of osteoporosis in elderly patients with ischemic stroke by ICAS.
