Abstract:
Objective:The metaanalysis aims to estimate the prevalence of suicide plan among college students in mainland China, and to provide more clues and reference for control and prevention of suicide.
Methods:The relevant studies were systematically searched via electronic databases (PubMed，Embase，CNKI，Wan Fang Data，VIP). We only selected original articles that either reported on Chinese retrieval words of "college students" "undergraduate" "university" "college" "colleges and universities" "suicide plans" "detection rate" "prevalence" "report rate", and the English retrieval words of "undergraduate" "college" "university" "suicide" "suicidality" "suicide plans" "suicidal plans suicide intending" "prevalence" "report rate" "detection rate" "China" "Chinese". And Stata 12.0 software was used to make a metaanalysis of the data.
Results:A total of 18 eligible studies, with 47 071 college students, were finally included. The maximum and minimum reported prevalence of suicidal plan among college students in China mainland was 4.4%(95%CI: 3.4%-5.4%).Subgroup analyses showed that the pooled estimate of suicidal plan of boys(5.4%) was higher than girls’(4.2%); The prevalence among college students from earth, middle and west areas were 5.1%，2.7%，4.5%, respectively; The prevalence among college students in 2010 and after (4.4%)was higher than that before 2010(4.3%), The prevalence among college students of life time suicide plan (4.9%)was higher than that during the past 12 months(4.0%), but there was no statistical significance in the subgroup(P>0.05) . Sensitivity analysis suggested that the results of metaanalysis were relatively stable, while funnel plot analysis suggested that publication bias might exist.
Conclusion:Prevalence of suicidal plans among college students in mainland China is respectively low, and there was no statistical significance in gender, region, the period of time and simple size.
