Because medically useful information could also be gathered through hospital-based studies, the aim of this study was to assess the prevalence, awareness, treatment, and control of HT among the elderly at a university hospital in Turkey. A total of 3,038 elderly were enrolled. Overall, 75.1% of the patients had HT. Among the hypertensive elderly, 88.9% were aware that they had HT, and only 20.9% had BPs that were under control. The low prevalence of control, even among individuals aware of their HT, suggests that the education of health care providers at all stages of professional training is especially important.
