Background/Aims: In France, geographic access to medical care may affect the diagnosis of hepatitis C. The aims of this study were to compare the detection rates of hepatitis C in urban and rural areas after adjusting for distance to medical care, and evaluating the impact of the place of residence on patients' clinical characteristics. Methods: Between 1994 and 2001, 1938 newly detected cases were recorded in a French population of 1,005,817 inhabitants. Age and sex-adjusted detection rates for 105 inhabitants were estimated for urban and rural areas and for classes of distance to the nearest practitioner. Results: Detection rates were lower in rural than in urban areas [14.1, (95CI: 12.5-15.7) versus 24.7, (95CI: 23.526.0)] and decreased as the distance to the general practitioner increased [27.0, (95CI: 25.5-28.4) versus 13.7, (95CI: 12.1-15.3) for a cutoff value of 1.5 km]. In multivariate analyses, detection rates were only influenced by the distance to general practitioner. Hepatocellular carcinoma at diagnosis was more frequent among rural than among urban patients (adjusted OR = 2.28, 95CI: 0.97-5.39, P = 0.059). Conclusions: A poorer geographic access to care explained the lower detection of hepatitis C in rural areas. Hepatocellular carcinoma was more frequent in rural patients. It may result from later detection and/or involvement of environmental factors on hepatocarcinogenesis. (c) 2005 European Association for the Study of the Liver. Published by Elsevier B.V.
