Prenatal adolescent care is characterized by technical actions seeking to provide assistance from the perspective of comprehensive care. The Community Health Agent Program/Family Health Program (PACS/PSF) is a strategy for implementing the changes envisaged, which motivated this scientific investigation. The scope of the research was to assess prenatal care to pregnant adolescents by health professionals of PACS/PSF and analyze it from the standpoint of comprehensive care. It is a qualitative study, with comprehensive care as its theoretical focus. It was conducted in PACS/PSF units in a city in the State of Bahia, and the subjects of study were the practitioners who treat pregnant adolescents. The empirical material was produced by means of semi-structured interviews and non-participative observation in consultations and homecare visits and was analyzed using the speech analysis technique. This revealed that prenatal care for adolescents is provided using the biomedical model, where compliance with institutional protocols and routines takes precedence over considering the specific aspects of the adolescent. Thus it is far removed from comprehensive care, in that the practices are guided by ideological adherence to a model that fails to grant pregnant adolescents the opportunity to be treated as individuals.
