Prediction of Hypertension Based on the Quantity and Quality of Sleep in Adults: Results of the First Phase of Shahedieh Cohort Study 2015-2016

Background: The prevalence of high blood pressure is a serious concern in developing countries. The present study aimed to examine hypertension based on the quantity and quality of sleep in adults. Methods: This descriptive study was conducted on the data of the first phase of Shahedieh cohort study in Yazd (Shahdieh, Zarch, and Ashkezar cities), Iran during 2015-2016. The variables of the study were assessed by the questions regarding the sleep status and blood pressure measurement. To analyze the data SPSS version 20 was used. Results: The results showed that blood pressure in people who sleep less than 6 h at night was significantly higher than those who obtain 6-8 h night′s sleep (P = 0.001). Moreover, the findings indicated systolic blood pressure is significantly related to taking naps during the day, using sleeping pills, and restless legs syndrome during sleep (P 0.001). According to the results, 98% of the systolic blood pressure variance and 80% of the diastolic blood pressure variance were explained by the sleep-related variables. Conclusion: Sleep duration at night is a strong predictor for systolic and diastolic blood pressure.
