Suicide among farmers: a scoping review of trends across countries and cultures
摘要
Despite the common perception of farming as a tranquil and healthy way of life, the agricultural industry has the highest fatality rate. To comprehensively assess suicide within a specific group, it is essential to consider biological, psychological, and social variables. However, research on the risk factors associated with farmer suicide is limited, with only a few nations having reported on the issue. This scoping review aims to systematically assess the evidence on factors related to farmer suicides across different countries and cultural contexts, providing insights to inform suicide prevention strategies. A comprehensive literature search was conducted using PubMed, Google Scholar, and PsycINFO databases for studies published up to July 1, 2024. Eligible studies included original research articles examining farmer suicides or suicidality (suicidal ideation, attempts, and deaths). Data were extracted and synthesised to identify key risk factors, including financial stress, psychiatric comorbidities, social isolation, and access to lethal means. Study quality was assessed using the National Heart, Lung, and Blood Institute (NHLBI) quality assessment tool and the Joanna Briggs Institute (JBI) checklists. The 26 articles analysed in this review identified several significant factors associated with farmer suicides, including drought, financial and administrative issues (e.g., debt associated with farming expenses), relationship difficulties, rural lifestyle and mentality, psychiatric comorbidities, substance use, coping strategies, and ready access to firearms. This article presents information regarding the escalating burden of suicide among farmers and the associated factors, encompassing biological, social, and psychological dimensions. Further interventional studies are necessary to understand these factors better, as many can be partially controlled through mental health interventions and government policies.
