The Relationship Between Sleep Quality and Blood Pressure in Hypertensive Patients at the Sawah Lebar Community Health Center in Bengkulu City in 2025

Abstract

Hypertension is a major global health problem and a leading risk factor for cardiovascular diseases. One of the factors influencing blood pressure regulation is sleep quality, which is often overlooked in clinical management. This study aimed to analyze the relationship between sleep quality and blood pressure among hypertensive patients. This study employed an analytical observational design with a cross-sectional approach. A total of 60 respondents were selected using purposive sampling. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), while blood pressure was measured using a sphygmomanometer. Data were analyzed using univariate and bivariate methods, with the chi-square test at a significance level of 0.05. The results showed that 65% of respondents had poor sleep quality and 70% had uncontrolled blood pressure. The chi-square test indicated a significant relationship between sleep quality and blood pressure (p = 0.021). Respondents with poor sleep quality were more likely to have uncontrolled blood pressure compared to those with good sleep quality. In conclusion, sleep quality is significantly associated with blood pressure in hypertensive patients. Improving sleep quality may serve as an important non-pharmacological strategy in blood pressure management.
