Key result
Poor sleep quality linked to higher rates of Stage 2 hypertension, affecting ~32% vs. none.
Why the study?
Hypertension is highly prevalent and a major cardiovascular risk factor, with poor sleep quality potentially increasing blood pressure via sympathetic nervous system activation.
Cross-Sectional (n=70)
No
Absolute Event Rate: 31.9% vs 0%
p-value: p=0.002
Poor sleep quality is significantly associated with higher severity of hypertension, highlighting the importance of sleep hygiene in blood pressure management.
Should not yet change hypertension care; hypothesis-generating for sleep interventions in prospective trials.
Background: Hypertension is one of the non-communicable diseases with a high prevalence and is a major risk factor for cardiovascular disease. Poor sleep quality can increase the activity of the sympathetic nervous system, which may trigger an increase in blood pressure. In the working area of the Parongpong Community Health Center, hypertension is the highest non-communicable disease case, therefore attention to related factors, including sleep quality, is needed. Objective: To determine the relationship between sleep quality and blood pressure in hypertensive patients in the working area of Parongpong Community Health Center. Methods: This study used a quantitative method with a correlational study design. The population in this study consisted of all hypertensive patients registered at the Parongpong Community Health Center. The sampling technique used accidental sampling. Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI), while blood pressure was categorized based on the degree of hypertension. Data analysis was performed using the Chi-Square test. Results: The results of the study on 70 respondents showed a significant relationship between sleep quality and blood pressure in hypertensive patients. The Chi-Square statistical test showed a p-value of 0.002 (p < 0.05). Conclusion: There is a significant relationship between sleep quality and blood pressure in the working area of the Parongpong Community Health Center.

Saputri et al. (2026) conducted a cross-sectional in Hypertension (n=70). Poor sleep quality vs. Good sleep quality was evaluated on Degree of hypertension (Stage 1 vs Stage 2) (p=0.002). Poor sleep quality was significantly associated with worse blood pressure, with 31.9% of poor sleepers having Stage 2 hypertension compared to 0% of good sleepers (p=0.002).
