Background: Impaired sleep has significant negative impact on health. Adequate sleep duration not only maintains body function, but also prevents adverse cardiovascular outcomes. For instance, inadequate sleep has been associated with hypertension. Objective: to determine sleep quality among hypertensive patients and the point out the score differences between hypertensive and control groups using the Pittsburgh Sleep Quality Index on patients living in the central area of Saudi Arabia. Methods: case control study conducted among 73 already physician diagnosed hypertensive patients and 73 matched control non-hypertensive group from the central area of Saudi Arabia, during the period from 1 January to 31 May, 2018. Data were collected by personal interview with the hypertensive and control group and filling the questionnaire. We used the Arabic Pittsburg Sleep Quality Index (A-PSQI). Results: About two thirds (67.1%) of hypertensive patients were females and almost the proportions (68.5% Vs. 31.5%) in the control group. By using Pittsburgh Sleep Quality Index (PSQI) we found that, among hypertensive patients 71.2% had poor sleep quality and only 28.8% had good sleep quality. While in the control group 20.5% had good sleep quality and 79.5% poor sleep quality and there was insignificant difference in sleep quality between hypertensive patients and control (P=0.249). The Mean± S.D sleep quality global score was 8± 4.33 in hypertension patients and 7.16 ± 3.6 in the control group but the difference was statistically insignificant (P=0.370). Conclusion: from this study we concluded that By using Pittsburgh Sleep Quality Index (PSQI) we found that, there was insignificant difference in sleep quality between hypertensive patients and control (P=0.249).
