Survey Of Suicide Ideation And Suicide Attempters Among People Aged 18 And Older In Tianjin City

Objective: The objective of this study was to knowledge the prevalence of lifetime suicidal ideation and attempted suicide among people aged 18 and older in Tianjin city,and explore the potential related risk factors of them,so that we can provide scientific basis for the prevention of suicidal behavior in community population.Methods: Our study used the sample of mental health epidemiological survey conducted in Tianjin in 2011.A total of 15538 families were selected using the multi-stage and scale-based sampling method.A random person in each family aged 18 years and above and lived there for more than 3 months within the past six months was selected as the target of investigation.The investigation sonsisted of two stages of mental disorder screening and diagnostic interviews.At the screening stage,subjects were screened using the general health questionnaire(GHQ-12)and eight mental disorders scan problems.And a total of 11748 people completed the screening.According to the screening results,the subjects were divided into low-risk,middle-risk and high-risk three groups.In the diagnostic interview phase,10% of low-risk population,40% of middle-risk population and 100% high-risk population a total of 4563 people were randomly selected to complete the assessment of Structured Clinical Interview for DSM-IV-TR Axis I Disorders(SCID)and lifetime suicidal ideation and attempted suicide by psychiatrists.The final data was adjusted by statistically weighted.And SPSS23.0 statistical software was used for statistical analysis.In univariate analysis,the incidence of suicidal ideation and suicide attempt were compared by Chi-square test and logistic regression analysis was used to analyze the related risk factors.The difference was statistically significant at P <0.05.Results: 1.A total of 4438(97.3%)respondents completed the two-stage survey.The number of lifetime suicidal ideation and attempted suicide were 503 and 76,respectively.And the adjusted incidence rate for both was 5.00%(95%CI: 4.36%~5.64%)and 0.75%(95%CI: 0.49%~1.00%),respectively.2.Multivariate logistic regression analysis showed that female(OR=2.45,95%CI:1.80~3.33),hospitalization for physical illness(OR=1.62,95%CI:1.19~2.20),with religious beliefs(OR=2.66,95%CI:1.72~4.09),GHQ ≥ 4(OR=2.41,95%CI:1.73~3.36),PSQI> 7(OR=1.80,95%CI:1.19~2.73),diagnosis of mental disorders(OR=4.34,95%CI:3.17~5.93)and poor subjective economic status(OR=1.89,95%CI:1.38~2.60)were significantly associated with suicidal ideation.3.The main self-inflicted methods of attempted suicide were to take therapeutic drugs and use tools,accounting for 31.9% and24.3%,respectively.The prevalence of mental disorders in suicide attempters was 68.7%,of which 49.5% were affective disorders.4.Multivariate logistic regression analysis showed that diagnosis of mental disorders(OR=6.32,95%CI:2.88~13.85),poor subjective economic status(OR=3.03,95%CI:1.46~6.26),with religious beliefs(OR=5.53,95%CI:2.43~12.59),PSQI> 7(OR=2.84,95%CI:1.11~7.28)were significantly associated with attempted suicide.Conclusion: 1.The prevalence of lifetime suicidal ideation and attempted suicide in community people aged 18 years and older in Tianjin was lower than those of most other countries.2.The main methods of self-inflicted suicide attempt were to take medications and use tools.And the prevalence of mental illness among suicide attempters is high,among which affective disorder is the main one.3.Religious beliefs,diagnosis of mental disorders,poor quality of sleep,poor subjective economic status were common risk factors of suicidal ideation and attempted suicide.
