The landscape of suicide risk factors in Latin America

Suicide is a leading cause of death globally, with over 75 % of cases occurring in low- and middle-income countries (LMICs). Latin America, a severely underrepresented region in suicide research, has experienced a 6 % increase in its suicide rate from 2010 to 2016, contrasting with a global decline. In this commentary, we provide an overview of the epidemiological, social, and clinical factors influencing suicide in Latin America. We highlight the distinct trends in Latin America compared to other world regions, including the significant disparities in mental health care accessibility. Our review also considers the role of sociocultural factors such as strong family ties, traditional gender norms, and the impact of religiosity on stigma and care-seeking behaviors. Additionally, we address the lack of representation of Latin American populations in genetic studies on suicide, which hinders the identification of relevant biological markers and the development of tailored interventions. We call for increased research on the clinical, genetic, and social determinants of suicide in this region to better understand risk factors and ultimately inform suicide prevention strategies. Addressing this gap is critical for reducing suicide rates in Latin America.
