Introduction: The spreading of scientific knowledge occurs mostly by means of scientific journals, whose quality control is exerted, among other ways, by its indexation in bibliographical databases.The most important Brazilian journals, as well as those from other Latin American and Caribbean countries, in the health field are represented in the database LILACS-Latin American and Caribbean Health Science Literature Database.The access to it is open in the Virtual Library in Health.Considering that suicides are among the main causes of adolescent mortality, and that such phenomena can, in most cases, be prevented, it is necessary that information regarding suicidal behaviours is disseminated in the community and in the academy.This will stimulate the adoption of preventive measures and make the recognition of at-rick individuals easier.The present study aimed to evaluate scientific articles directed to Portuguese-speaking health professionals, available in LILACS, published from 2006 to 2010.Methods: Articles that contained, in the heading, the words suicide/s (suicidio/s), suicidal (suicida/s) and adolescent/s (adolescente/s), adolescence (adolesc(e)ncia) were searched, being selected those with available complete text on the Internet, in the Portuguese language.Results: Only nine articles were found, each of them in a different journal.Of these, two were qualitative studies and the other quantitative ones.One mentioned attempted and consummated suicides, one only attempts, four suicide planning, one the relation between sadness and suicide and the last one the prevention by means of the promotion of self esteem and problem solving skills.The aspects presented in the articles were following ones: a) Prevalence: No relation to skin colour or socioeconomic circumstances; girls attempt suicide more than boys; b) Risk factors: Depression, loneliness and sadness, isolation, difficulty of communication, having fewer than three friends, having friends who use drugs, being a victim of bullying or domestic violence, feelings of abandonment, indifference and unreliability of family members, poor school performance; lack of self confidence, being unable to find help, dwelling on problems, being unable to find alternatives; c) Protective factors: Good familiar support, ability to speak with the family, having three or more close friends; d) Importance of preventive activities in the school, together with the family and other sectors of the society, such as the health sector.Conclusion: Scientific journals, in Portuguese language, found in the database LILACs, presented very pertinent information, but are insufficient sources of information for health professionals in regard to suicidal behaviours in adolescents.
