[Access to primary health care in a sanitary district of Salvador].

The demand for and use of health services results from a set of determinants that include socioeconomic, demographic and health characteristics and organization of the supply of services. The scope of this paper is to define access to and use of the health services in two Family Health Units (FHUs) of the sanitary district of Liberdade, establishing the pattern of use and identifying factors related to socio-organizational and geographical access. A cross-sectional population-based survey was conducted on individuals aged between 20 and 75 resident in the area covered by the two FHUs.
