Objective To investigate the correlation between serum 25 hydroxyvitamin D[25 (OH) D] level and post-stroke depression in elderly patients with acute stroke.Methods Depression was assessed by Beck Depression Inventory (BDI),Burns Depression Checklist (BDC),and the Diagnostic and Statistical Manual of Mental Disorders Ⅳ in 231 elderly inpatients at 2-4 weeks after onset of acute cerebral infarction.According to the depression assessment,the patients were classified into four groups:normal group),depressive symptoms group,with mild depression group,and severe depression group.The cut-off point of 25 (OH) D level for post stroke depression was analyzed by receiver operating characteristic (ROC).Results The serum level of 25(OH)D was (23.0±1.6) nmol/L in all subjects,(25.0±1.7) nmol/L in normal group,(23.7± 1.6) nmol/L in depressive symptoms group,(22.4±1.5) nmol/L in mild depression group,(16.3± 1.5) nmol/L in severe depression group.Serum 25(OH) D level had significant differences between major depression groups and other three groups,while no significant differences were found between mild depression group,depressive symptoms group and normal group.Pearson correlation analysis showed that scores of BDI and BDC were inversely related to 25 (OH)D level (r=0.24 and-0.25,both P<0.01).ROC curve analysis showed that the cut off point of serum 25 (OH) D level for severe post-stroke depression was 21.6 nmol/L.Conclusions Serum 25 (OH)D level is inversely related to depression.Serum 25(OH) D level is reduced in patients with severe post stroke depression.
