The suicide rate in Guyana has consistently ranked as one of the highest in the world. This systematic review synthesises and critically analyses the existing literature on suicidal behaviours and ideation in Guyana.
Systematic review with narrative synthesis was conducted following PRISMA guidelines. PubMed, PsychInfo, CINAHL and SCOPUS databases were searched until 31 March 2021. Articles which included the analysis of suicidal behaviour or suicidal ideation using data collected in Guyana were eligible for inclusion. Articles relating to the Jonestown mass murder-suicide event were excluded. This review was pre-registered with PROSPERO [CRD42021247669].
The search resulted in 318 articles, of which 24 met eligibility for inclusion. The majority were quantitative (=18), relating to suicide mortality (=9), and suicide attempt and suicidal ideation (=9). Additionally, qualitative (=5) and mixed-method (=1) papers investigated the experiences of those bereaved by suicide, gatekeepers of suicidality, and adolescent students. Eleven studies were multinational, whilst 13 focused on Guyana. The quality of the publications varied.
Despite high annual suicide rates in Guyana, published research is very limited. This review found preliminary evidence for key risk groups; males, female youth, and Indo-Guyanese ethnicity. Pesticide poisoning was identified as the most common method for suicide in Guyana. There is a need for local research investigating the context and narrative of suicide to inform culturally tailored prevention strategies. This study was limited to a narrative synthesis and may be impacted by publication bias.
This research was supported by an Australian Government Research Training Program Scholarship through Griffith University Australia.

圭亚那的自杀率一直位居世界最高之列。本系统评价综合并批判性分析了圭亚那关于自杀行为和自杀观念的现有文献。
按照PRISMA指南进行系统评价并进行叙述性综合分析。检索了PubMed、PsychInfo、CINAHL和SCOPUS数据库，检索截止至2021年3月31日。纳入使用在圭亚那收集的数据对自杀行为或自杀观念进行分析的文章。与琼斯镇集体谋杀自杀事件相关的文章被排除。本评价已在PROSPERO上预先注册[CRD42021247669]。
检索得到318篇文章，其中24篇符合纳入标准。大多数文章是定量研究（=18篇），涉及自杀死亡率（=9篇）、自杀未遂和自杀观念（=9篇）。此外，定性研究（=5篇）和混合方法研究（=1篇）探讨了自杀 bereaved者、自杀守门人和青少年学生的经历。11项研究是跨国研究，13项研究聚焦于圭亚那。出版物的质量各不相同。
尽管圭亚那的年自杀率很高，但已发表的研究非常有限。本评价发现了关键风险群体的初步证据；男性、青年女性和印度裔圭亚那人。农药中毒被确定为圭亚那最常见的自杀方式。需要开展当地研究，调查自杀的背景和情况，为量身定制的文化预防策略提供依据。本研究仅限于叙述性综合分析，可能受到发表偏倚的影响。
本研究由澳大利亚政府研究培训项目奖学金通过澳大利亚格里菲斯大学提供支持。
