| Objective: To explore gender differences on the lifetime incidence of suicidal ideation and risk factors among Tianjin city residents aged 18 and older.Methods: The data were obtained from the mental health epidemiological survey in Tianjin in 2011.And multi-stage random cluster sampling was conducted according to the sequence of district/county street/township neighborhood committee/village,a total of 15,538 families were selected throughout Tianjin city.An adult aged 18 and order who has lived there for 3 months within 6 months was randomly selected from each family.The field investigation was divided into two stages: the first stage was conducted using general health questionnaires and screening questions to screening of mental disorders.According to the screening results,the interviewees were divided into three different grades: high-risk group,medium-risk group and low-risk group,In the end,75.6% of the respondents completed the first stage.The second stage was the interview for diagnosis of mental disorder.From the above three groups,all the people of high-risk group,40% of medium-risk group and 10% of low-risk group were selected to carry out the assessment of Structured Clinical Interview for DSM-IV-TR Axis I Disorders SCID and C-SSRS,a total of 4563 people.The final date was adjusted by statistically weighted,and using IBM SPSS Statistics19 to sort and analyze the data.The lifetime incidence of suicidal ideation in different gender groups was compared by chi-square test,Logistic regression analysis was used to compare the correlation factors of lifetime suicidal ideation between different gender,P < 0.05 was statistically significant.Results: 1.A total of 4,438 respondents completed the two-stage survey,including 2,554 females and 1,884 males.The adjusted lifetime incidence of suicidal ideation was 7.1% in females and 3.2% in males.Compared with males,the incidence of female suicidal ideation is higher,and the difference was statistically significant.2.The results of logistic regression analysis of related factors to lifetime suicidal ideation in males and females showed that GHQ scored ≥4(OR = 2.73,95%CI:1.74-4.27),diagnosis of mental disorders(OR = 5.85,95%CI: 3.87-8.83),for physical illness(OR = 1.39,95%CI:1.13-1.70),religious belief(OR = 2.46,95%CI:1.40-4.31),drinking(OR = 8.19,95%CI:3.03-22.14),smoking(OR = 2.17,95%CI:1.30-3.63)were risk factors for lifetime suicidal ideation in females,but older in g[aged 50-64(OR = 0.40,95%CI:0.19-0.86)and 65 years old and above(OR = 0.34,95%CI:0.13-0.89)] were protective factors for females.Besides,GHQ scored ≥4(OR = 4.32,95%CI:2.30-8.10),diagnosis of mental disorders(OR = 5.90,95%CI:3.33-10.41),religious belief(OR = 5.09,95%CI:2.10-12.34)were risk factors for lifetime suicidal ideation in males,length of schooling more than 13 years(OR = 0.24,95%CI:0.07-0.77),employment status[ref :house work: in work(OR = 0.08,95%CI:0.02-0.25),unemployed or out of work(OR = 0.06,95%CI:0.01-0.23),farmer(OR=0.08,95%CI:0.02-0.36)],medium and good subjective living conditions(OR = 0.34,95%CI:0.18-0.63)(OR = 0.21,95%CI:0.09-0.49),good or average subjective economic condition(OR = 0.36,95%CI:0.20-0.68),minority(OR = 0.02,95%CI:0.00-0.93),were protective factors for males.Conclusion: 1.Lifetime incidence of suicidal ideation among Tianjin city residents aged 18 and older was significantly higher in females than in males.2.There were significant differences on lifetime risk factors of suicidal ideation between male and female.Higher GHQ scores,diagnosis of mental disorders,religious belief were common risk factors for lifetime suicidal ideation in both males and females.Hospitalized with physical problems,young,drinking,smoking were unique risk factors for lifetime suicidal ideation in females.Low years of education,poor subjective living conditions,poor subjective economic conditions,the Han nationality were unique risk factors for lifetime suicidal ideation in males. |
