[The role of religion in the promotion of health, in the prevention of violence and in the rehabilitation of individuals involved in criminal activity: literature review].

This is a review of the literature on the role of religion in the promotion of health, the prevention of violence and the rehabilitation of individuals involved in criminal activities. Research was conducted in the Medline through PubMed, Lilacs, Scopus, Social Index with full text, Sociological abstracts and Social services abstracts databases. Twenty-nine essays in Portuguese, English and Spanish were selected and analyzed between 1990 and 2011. The results indicate the function of the religious group and the role of religion in the rehabilitation of individuals, the prevention of criminal involvement, corrective orientations and in social iniquity environments. A debate is presented on the main themes revealed, highlighting the multiplicity of religious roles, their influence over prisoners, as a social control and support base and its influence on mental health promotion and quality of life. The relation between religion and the public sphere is discussed, emphasizing the role of religious groups and the fragility of the State in providing basic public policies. Despite revealing the successful role of religion in violence prevention and in rehabilitation, some studies question this relation and highlight the conflicts between the concepts employed and the final results.
