Objective:To investigate the trend and related factors of suicidal ideation in college students over a nine-year period.Methods:A multi-stage stratified sampling method was employed to select mental health survey data from college students in Beijing between 2007 and 2015(n=9 716).The survey utilized the items of suicidal ideation and behavior from the National Comorbidity Survey Replication(NCS-R),Center for Epidemiologic Stud-ies-Depression Scale(CESD),and Multidimensional Scale of Perceived Social Support(MSPSS).Linear decompo-sition regression analysis was conducted to examine the factors contributing to the decline in suicidal ideation.Results:The average suicidal ideation score decreased from 0.24 in 2007 to 0.13 in 2015.There was a positive correlation between suicidal ideation score and CESD score(r=0.30,P<0.001),while a negative correla-tion existed between suicidal ideation scores and MSPSS scores(r=-011,P<0.001).The results of the regres-sion analysis revealed that the decline in suicidal ideation was more significant in female students than in male students(β=-0.030,-0.017,Ps<0.05),and urban college students exhibited a faster reduction in suicidal idea-tion than their rural counterparts(β=-0.026,-0.016,Ps<0.05).Individuals born in later cohorts had higher suicidal ideation scores than earlier cohorts(β=0.012,P<0.05).Conclusion:It suggests that suicidal ideation has shown adecreasing trend during the survey period,while it is more prevalent in younger cohorts.In addition,depres-sion and social support are found to be associated with suicidal ideation.
