Prediction of Hypertension Based on the Quantity and Quality of Sleep in Adults: Results of the First Phase of Shahedieh Cohort Study ۲۰۱۵-۲۰۱۶

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 ۲۰۱۵-۲۰۱۶. The variables of the study were assessed by the questions regarding the sleep status and blood pressure measurement. To analyze the data SPSS version ۲۰ was used. Results: The results showed that blood pressure in people who sleep less than ۶ h  at night was significantly higher than those who obtain ۶-۸ h  night′s sleep (P = ۰.۰۰۱). 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 < ۰.۰۰۱). According to the results, ۹۸% of the systolic blood pressure variance and ۸۰% 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.
