ABSTRACT
Objective To analyze the risk factors of socio-demographic and clinical characteristics related to sui?cide risk in misdiagnosed bipolar disorderⅡ(BPⅡ) treated for major depressive disorder. Methods A total of l478 con?secutive major depressive disorder patients were interviewed with the Mini International Neuropsychiatric Interview (MINI) in 13 major mental health centers in China. Of the 1478 patients, 190 patients were diagnosed BPⅡ, who were divided into two groups (nonsuicidal risk and suicidal risk) with the suicidality module of MINI. Logistic regression was performed to evaluate significant risk factors associated with suicide risk in misdiagnosed BPⅡtreated for major depres?sive disorder. Results Of the 190 patients, 116 were in the nonsuicidal risk group and 74 were in the suicidal risk group. In comparison to the nonsuicidal risk group, the suicidal risk group had younger age [(34.45 ± 11.18) vs.(37.23 ± 13.22), P=0.008], earlier age at onset [(26.20 ± 9.16) vs. (30.37 ± 11.59), P=0.007], and more suicidal ideation (82.4%vs. 53.4%, P=0.001). Logistic regression analysis showed that age (OR=0.969,95% CI:0.945~0.993) and depressive epi?sodes with suicidal ideation (OR=4.129,95%CI:2.030~8.397) were significantly associated with suicide risk in patients of misdiagnosed BPⅡtreated for major depressive disorder (P<0.05). Conclusions Younger age, severer suicidal ide?ation may be potential independent risk factors to suicide risk in BPⅡwith misdiagnosed with major depressive disor?der.
ABSTRACT
Objective:To compare the suicidality risk in major depressive disorder (MDD)patients with and without anxious characteristics,and analyze the risk factors of suicidality in MDD patients. Methods:This was a secondary analysis of the data from the Diagnostic Assessment Service for people with Bipolar Disorders in China (DASP),which was initiated by the Chinese Society of Psychiatry (CSP),from September 1,2010 to February 28, 201 1. Based on the anxious module and suicide module of Mini International Neuropsychiatric Interview (M. I. N. I),1 172 MDD patients were classified as suffering from anxious MDD (n=728,62. 1%)and non-anxious MDD(n=444,37. 9%). Logistic regression was employed to examine the risk factors of suicidality in MDD pa-tients. Results:Among the anxious MDD patients,331 (45. 5%)of them had suicidality risk. And 54(12. 2%)of non-anxious MDD patients had suicidality risk. Compare to the non-anxious group,the anxious MDD patients had significantly higher suicidality risk (P<0. 00 1 ). Logistic regression analysis showed that more frequent depressive episodes (OR=2. 07 ),depressive episodes with psychotic symptoms (OR=2. 0 1 ),comorbid with anxious charac-teristics (OR=3. 18)or melancholic characteristics (OR=2. 90)were associated with suicidality risk in patients with MDD. Conclusion:It indicates that the anxious MDD patients may have higher suicidality risk than non-anx-ious MDD patients,and more frequent depressive episodes,depressive episodes with psychotic symptoms,comorbid with anxious characteristics or melancholic characteristics may be risk factors of suicidality in patients with MDD.
ABSTRACT
Objective To analyze the risk factors of socio-demographic and clinical characteristics related to sui?cidal attempt in major depressive disorder (MDD) patients with anxious characteristics. Methods Based on the anxious module of Mini International Neuropsychiatric Interview (MINI), a total of 728 anxious MDD patients from 13 major men?tal health centers in China were classified as suicidal and non-suicidal attempt groups. Further analyses regarding risk factors of suicidal attempt in anxious MDD patients were performed by the multivariate logistic regression analysis. Re?sults Among the 728 patients with anxious MDD analyzed, 135 (18.5%) of them had suicidal attempt and 593 (81.5%) had non-suicidal attempt. Compared to the non-suicidal attempt group, patients with suicidal attempt had significantly earlier age onset[(32.3 ± 11.9) vs. (35.3 ± 13.1)], more lifetime depression episodes (median:2 vs. 2), more number of ad?missions (median: 1 vs. 0), more frequent depressive episodes (14.8% vs. 7.4%), more atypical characteristics (25.9%vs.15.0%), more suicidal ideation (78.5%vs. 50.3%) and more antidepressant use (81.5%vs. 71.2%). Logistic regression analysis showed that number of admissions (OR=1.18, 95%CI:1.02~1.37), frequent depressive episodes (OR=2.10, 95%CI:1.14~3.68), depressive episodes with suicidal ideation (OR=3.55, 95%CI:2.28~5.54) were associated with suicidal at?tempt in MDD patients with anxious characteristics (P<0.05). Conclusions More number of admissions, more frequent depressive episodes, comorbid suicidal ideation may be risk factors of suicidal attempt in anxious MDD patients.
