The objective of this work was to study the use of the Internet and the quality of the websites for postgraduate public health courses in France, and to compare them with equivalent courses in the United States of America. Between June 2004 and January 2005, the authorized public health diplomas proposed in France and in the United States were inventoried and listed, and then all websites of these public health diplomas were systematically visited and reviewed using a standardized questionnaire. In France, 36 public health courses (7 post graduate diplomas [DEA], 13 Masters degrees [DESS] and 16 masters of public health [MPH]) were identified and selected from 53 websites. Information on student profiles, prerequisite skills, the courses' curricula and program descriptions and the potential career opportunities were more frequently available for the MPH compared to the DEA and DESS. In United States, 66 MPH and 127 Master of Science in Public Health (MSPH) programs were accredited. The target public and validation methods were more often indicated on the American sites, while the prerequisite skills were more frequently found on the French sites. The recent implementation of the LMD (Bachelor's-Masters-Doctoral degrees) education system in France has encouraged the utilisation of Internet as an information and communications tool for the presentation and marketing of these new diplomas.
