The effect of long-term partial sleep deprivation on blood pressure in young men in the military

AIM To evaluate the relationship between hypertension and partial sleep deprivation in young male soldiers.

METHODS Young male soldiers under partial sleep deprivation were divided into two groups according to the days they had been partially sleep deprived. Blood pressure, pulse rate, age, height, body weight and other indicators were collected to compare the differences in blood pressure and pulse rate between the two groups, and the logistic regression was used to analyse the risk factors of hypertension.

RESULTS Compared with the short-term PSD group, the long-term PSD group has older age (P<0.01), larger body mass (P<0.05), higher smoking index (P<0.05), and longer average PSD days (P<0.01); There was no statistically significant difference in BMI, conscription blood pressure, family history, smoking history, and SAS standard score. There was no statistically significant difference in pulse rate between the long-term and short-term groups. The detection rate of hypertension in the long-term group was higher than that in the short-term group (using Chi square segmentation, 8.1% vs. 1.4%, P<0.05), and the proportion of Normal height blood pressure was higher than that in the short-term group (using Chi square segmentation, 54.7% vs. 28.2%, P<0.01). The logistic regression analysis results showed that there is a higher risk of elevated blood pressure when the cumulative number of days of sleep deprivation exceeds 12 months (P<0.01).

CONCLUSION  Both systolic and diastolic blood pressure increased significantly when partial sleep deprivation lasted for more than 12 months. The proportion of high-normal blood pressure increased significantly when partial sleep deprivation lasted for more than 12 months. Increased blood pressure was associated with cumulative days of partial sleep deprivation. The risk of high blood pressure was significantly increased when partial sleep deprivation lasted.
