ABSTRACT

ObjectiveTo analyze the suicidal behavior in hospitalized patients with major depression and its influencing factors. MethodsA total of 1 000 patients with major depression admitted to our hospital from January 2017 to July 2021 were selected as the research subjects to investigate the status quo of suicidal behavior of the enrolled patients. According to the survey results， the patients were divided into suicidal behavior group and non-suicidal behavior group， and the related factors affecting their suicidal behavior. ResultsA total of 511 cases （51.10%） of the patients with major depression committed suicide in hospital， including 271 cases （27.10%） of suicidal ideation， 186 cases （18.60%） of attempted suicide， and 54 cases （5.40%） of suicide death. 489 patients （48.90%） did not commit suicide. Univariate analysis showed that there were significant differences in age， gender， marital status， loss of interest or pleasure， anxiety， sense of worthlessness or self-guilt， sleep status， personality， depressive episodes and paranoia between the suicidal behavior group and the non-suicidal behavior group （all P<0.05）. Logistic multifactorial regression analysis showed that age ≤28 years （OR=1.54）， female （OR=1.93）， anxiety （OR=1.61）， sense of worthlessness or self-guilt （OR=1.85） and paranoia （OR=2.15） were all independent predictors of suicidal behavior in the patients with major depression. ConclusionThe incidence of nosocomial suicide in patients with major depression is high. Early onset age， female， anxiety， sense of worthlessness or self-guilt， more depressive episodes and paranoia are independent risk predictors of suicide in patients with major depression. This finding can be used for clinical intervention to reduce the occurrence of suicide in patients.
