Suicide Research in Mainland China, Hong Kong, and Macau Over Three Decades

Abstract

Abstract. Background: China accounts for 15% of the global suicide death toll, yet suicide research efforts in the country are not well known by international colleagues. Aims: We aimed to outline the development of suicide research in China, appraise research findings, and identify key contributors. Method: English and Chinese research publication databases were systematically searched and relevant papers were reviewed. Chinese and English publications were compared. Results: There are almost 10 times more Chinese publications than English ones. The research focuses of and key contributors to the Chinese and English literature exhibit more differences than commonalities. The field experienced rapid expansion in the new millennium with more and higher quality publications and more funding support. Psychosocial-oriented perspectives guided most of the papers. Poisoning by pesticide as a suicide method and youth as a subpopulation group received the most research attention. Limitations: The scoping review does not provide in-depth syntheses on specific topics and does not include more recent publications. Conclusion: Research on suicide in China has been actively carried out during the 30-year period we reviewed, which might have contributed to suicide prevention in China. Research gaps identified by the review should be addressed to sustain the achievements.
