This survey was designed to investigate the socio-demographic characteristics of and utilization of a Primary Heath Care Unit (PHCU) by Roma people (Turkish Gypsies), who live in the coverage area of Muradiye Primary Health Care Unit, as compared to members of the general population. This was a cross-sectional field study involving members of the Muradiye PHCU district. The study population comprised 127 Turkish gypsies resident in the region and 302 households selected by a stratified random sampling method. 889 household members were interviewed face-to-face at their home by means of a structured questionnaire. When the two sample groups were compared in terms of their social security coverage, rates of unemployment and educational levels, the situation of the Turkish Gypsies was found to be worse than that of the other members of the general population. 63% of the Gypsies applied to the PHCU because of health problems and 87% of these cases were treated successfully. Among those people making use of the PHCU services 47% evaluated them as being "satisfactory". Access to the PHCU services was found to be conditioned by educational level, being a Gypsy, the possession or not of a Green Card (available only to highly indigent people), whether or not the services were provided free of charge and the possession or not of social security coverage. Muradiye PHCU is well known and highly appreciated in its coverage area and is used by almost all of the residents. The main reason for the significant discrepancies in the level of health care obtained by the two population groups is the Gypsies' poorer economic situation. Among the Gypsies, the leading category of low rate social security coverage is the Green Card, which is granted to the very poor in order to reduce these inequalities. Unfortunately, the Green Card does not provide financial support for ambulatory care.
