Abstract
Background: Sleep quality is a potential factor associated with blood pressure control. Studying this relationship may help identify questions for further investigation in adults receiving treatment for essential hypertension.
Objective: To demonstrate how a cross-sectional study examining sleep quality and blood pressure control could be reported using synthetic data.
Methods: An illustrative dataset representing 200 adults with treated essential hypertension was constructed. Sleep quality categories were defined using the Pittsburgh Sleep Quality Index (PSQI): scores ≤5 represented good sleep quality and scores >5 represented poor sleep quality. For this example, controlled office blood pressure was defined as systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg. Frequencies, percentages, and a crude odds ratio were calculated from the constructed counts.
Synthetic results: Of 200 illustrative participants, 120 (60.0%) were assigned poor sleep quality. Uncontrolled blood pressure was assigned to 84 of these 120 participants (70.0%), compared with 32 of 80 participants with good sleep quality (40.0%). The crude odds ratio for uncontrolled blood pressure was 3.50.
Conclusion: The synthetic dataset illustrates an association between poor sleep quality and uncontrolled blood pressure. It provides no clinical evidence and cannot establish causation. A real study would require ethical approval, participant recruitment, standardized measurements, and analysis of potential confounders.
