[Health indicators in Tunisia, trends in regional disparities over the last thirty years].

The measure of health indicators on a regional-scale seems more interesting then the measure on a national-scale. It allows us to study differences between regions and their evolution. In order to know the time trend's disparities between regions, we have studied seven indicators, concerning different types of the World Health Organisation's classification, using data from yearly statistics and results of decennial census. Regional disparities are evaluated by a ratio between the highest regional value and the lowest regional value. This study showed us a global trend to the decline of regional disparities about indicators that we have studied. The improvement of health care resources indicators and socioeconomic's indicators, in the process of time, is associated with the improvement of health status indicators. The study of regional disparities makes possible to target actions for health in order to promote health's equity between regions.
