ABSTRACT

Objective To analyze the risk factors of socio-demographic and clinical characteristics related to anxious symptoms in bipolar depression patients(BDP).Methods This was a secondary analysis of data from the Diagnostic Assessment Service for People with Bipolar Depression in China(DASP)from September 1,2010 to February 28,2011.According to the criterion that comorbid anxiety or not, BDP(n=306)were divided into comorbid anxiety group(n =200)(65.4％)and without anxiety group(n =106)(34.6％).Further analysis for risk factors of anxious symptoms in BDP was performed by the multivariate logistic regression analysis.Results BDP with anxiety were younger(35.10± 11.09), younger at illness onset(27.93-± 10.04), ruore male(t =4.603, P＜0.05), more lifetime episodes(3.21 ± 3.77), frequently episodes(t =17.328,P＜0.05),inducement onset(t=14.859,P＜0.05)and more seasonal episodes(t=8.300,P＜0.05)compared with BDP without anxiety.Logistic regression analysis showed that inducement onset(OR=5.023)and episodes frequency(OR=10.852)was significantly associated with anxious symptom(P＜0.05).Conclusion The finding indicates that postpartum onset and depressive episodes frequency may be risk factors of bipolar depression with anxiety.
