The aim of this study was to investigate whether depressive symptoms are associated with suicidal ideation among university students in China.Five Chinese and English electronic databases (EBSCO, PubMed, Chinese Web of Knowledge, Wanfang, and Weipu) were searched to identify relevant studies. Cross-sectional studies published from 2000 to 2016 reporting about the association between depressive symptoms and suicidal ideation among university students in China were used for meta-analysis to approximate the overall association between depression and suicidal ideation among university students in mainland China. StatsDirect 3 was used for meta-analysis of included literatures.Of 513 initially identified references, 44 studies were selected, including 88,431 participants with depressive symptoms. The combined odd ratio of the relationship was 2.174 (95% confidence interval: 2.027-2.333; P < 0.0001).There exists a moderate association between depressive symptoms and suicidal ideation among university students in China, and depressive symptoms contribute to the development of suicidal ideation. In particular, university students from western regions of China, from nonmedical background, should be provided more psychological and clinical assistance.
本研究旨在调查中国大学生的抑郁症状与自杀意念之间是否存在关联。检索了五个中英文电子数据库（EBSCO、PubMed、中国知网、万方和维普）以识别相关研究。纳入2000年至2016年发表的关于中国大学生抑郁症状与自杀意念之间关联的横断面研究进行荟萃分析，以估算中国大陆大学生抑郁与自杀意念之间的总体关联。使用StatsDirect 3对纳入文献进行荟萃分析。在最初识别出的513篇参考文献中，选取了44项研究，包括88431名有抑郁症状的参与者。该关系的合并比值比为2.174（95%置信区间：2.027 - 2.333；P＜0.0001）。中国大学生的抑郁症状与自杀意念之间存在中度关联，且抑郁症状会促使自杀意念的产生。特别是来自中国西部地区、非医学背景的大学生，应给予更多心理和临床援助。
