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.
