Objective To analyze the risk factors related to suicide in bipolar disorder patients. Methods The included patients were divided into the group with or without suicide. Univariate analysis were used, then, the factor of suicide was taken as the dependent variable, and the demographic data and clinical characteristics were taken as the independent variables to conduct a stepwise multivariate Logistic regression analysis. Results The rate of having anxiety symptoms in BPD patients of suicidal risk group was significantly higher than that in the group without suicidal risk (P＜0.001), having predisposing factors of the suicidal risk group was significantly higher than that in the group without suicidal risk (P=0.001), and the incidence of family history of mental illness in the group with suicidal risk was significantly higher than that in the group without suicidal risk (P=0.016). The results of multivariate logistic regression analysis were the factors of high suicidal risk were with anxiety symptoms (P＜0.001) and with predisposing factors (P=0.005). Conclusions: The BPD patients with suicidal risk who comorbid with anxiety symptoms and predisposition were high.
