A simple and effective method to teach patients about high blood pressure and obesity

It is an open question whether information about hypertension and obesity increases compliance with therapy. Nevertheless, patients increasingly demand precise but simple and comprehensive information. A simple slide programme is described which can be demonstrated in any waiting room. The learning effect was assessed in 1083 subjects, of whom 485 had seen the programme completely; 256 subjects served as controls. The percentage of subjects with good or excellent knowledge about hypertension and obesity rose from 22.8% in the controls to 64.2% in the experimental group. Age was the only factor influencing learning, but this was of no great importance in subjects under 70. In particular, social status did not have any significant effect on learning. This programme may be an ideal tool to inform patients about hypertension and obesity and to study the influence of information on compliance with therapy.
