Introduction: Community Health Agents are unique health workers in the Brazilian Unified Health System.Their profile is more social than technical and their main function is to create a link between the health team and the community in a defined geographical area.But they have other important responsibilities, which include: analyzing community needs, acting in health promotion and disease prevention, taking part in basic hygiene and environmental improvement actions, as well as in health team meetings and other health events within the community.Their work tools include home visits, interviews, registration of families, community mapping and community meetings.The involvement of these health agents with the communities makes them important in the prevention and identification of suicidal behaviours within the geographical areas where they work.The purpose of this study was to analyze the knowledge and conceptions related to suicidal behaviours of these professionals, in the Brazilian inland city Diamantina.Methods: Semi-structured individual interviews were conducted with twelve Community Health Agents from different Family Health Program units.The interviews, about suicide, suicidal behaviours and its prevention, and contact with individuals with these behaviours, were recorded, transcribed and then analyzed.The study was evaluated and approved by the University Research Ethics Committee.Results: Most of the respondents had had, at some moment of their professional or personal lives, contact with people with suicidal behaviours.They reported believing that the suicidal behaviours are related to youth (emotional immaturity), family and relationship conflicts, economic difficulties, psychological and psychiatric disorders, the consumption of alcohol and other drug, and lack of spirituality and faith.Although many considered suicidal behaviours to occur in relation to intense suffering, these behaviours are sometimes seen as a way to escape from ones problems, and thus are seen as cowardly and selfish.According to the Community Health Agents, such behaviours can be prevented, and their profession can contribute to this.The cited strategies included conversation, family attention and psychological or psychiatric care.Conclusion: Although Community Health Agents already have reat experience in suicidal behaviours, educational activities on the subject are needed in order to realize the important work of detecting and preventing suicidal behaviours in their communities.
