Self-monitoring of psychological stress-induced blood pressure in daily life using a wearable watch-type oscillometric device in working individuals with hypertension


This study investigated psychological stress-induced blood pressure (BP) elevation according to self-measured data obtained by a wearable watch-type oscillometric device for multiple days in 50 working hypertension patients (mean ± SD age: 60.5 ± 8.9 years; 92.0% men; 96% treated for hypertension). Participants were asked to self-measure their BPs at five predetermined times as well as at any additional time points at their own discretion under ambulatory conditions for a maximum of 7 days. At the time of each BP measurement, participants self-reported their location, emotion, and degree of stress. A total of 1220 BP readings with self-reported situational information were obtained from 50 participants over 5.5 ± 1.2 days. Systolic BP (SBP) and diastolic BP (DBP) measured during moments of self-reported negative emotions (i.e., anger, tension, anxiety, or sadness) were significantly higher (5.0 ± 1.3 and 2.0 ± 0.8 mmHg, both p < 0.05) than those during moments of self-reported positive emotions (i.e., happiness or calm). SBP/DBP were significantly increased under a moderate or high degree of stress by [4.5 ± 1.1]/[2.5 ± 0.7] and [10.2 ± 3.0]/[4.7 ± 1.8] mmHg, respectively. As a result, it was estimated that SBP/DBP increased 15.2/8.5 mmHg in the presence of highly stressful negative emotions. In conclusion, self-measurement of BP monitoring with a wearable device for multiple days is a feasible method to detect daily stress-induced BP elevation in working adults.
