[Blood pressure: knowledge and behavior].

Knowledge about blood pressure and practice in terms of its measurement are two important indicators for problem areas in cardiovascular disease prevention. This paper analyses these two indicators based on a representative Health Survey (SOMIPOPS) in order to illustrate the potential of such surveys. The results demonstrate that interesting clues to preventive action can indeed be obtained. In addition, time series analyses could potentially be a basis for the continuous evaluation of health services in this area.
