Abstract : Hypertension presents a distinctive problem in treatment. One of the major contributing factors to poor control of blood pressure is patient adherence. In this study, we investigated adherence in elderly hypertensive patients who had difficulty accessing medicines due to living far from the health care center about age and the duration of illness. It was a descriptive exploratory. Samples of this study were elderly hypertensive patients who lived far from the healthcare center in several districts in Pekanbaru in the Province of Riau, Indonesia. Data was collected using MGL (Morisky, Green, and Levins) adherence scale. A total of 110 respondents, divided into four groups (middle age, 45-59; elderly, 60-74; old, 75-90; and very old, >90 years old). Adherence measurement showed that 41 (37.27%) patients had medium adherence, and 69 (62.73%) patients had low adherence to their antihypertensive. The patients with the highest rate of low adherence were the elderly (35, 31.82%) with duration of illness of 1-5 years (30, 27.27%). Based on the Gamma test, the correlation was weak, and the direction is negative (-0.259), and there is no significant relationship between age groups, and medication adherence (p=0.120). The correlation between duration of illness with adherence was very weak (-0.071) with negative direction, and there is no significant relationship between duration of illness and medication adherence (p=0.7). Most of the respondents had low medication adherence. There was a weak correlation; between age group with medication adherence, and there is a very weak correlation between duration of illness with medication adherence..
