Demographic factors affecting nocturnal blood pressure variability in the general population: results of a large digital study using an optical blood pressure monitor

This digital investigation showed greater night-to-night variability of nocturnal systolic BP in male and young subjects, and greater variability of nocturnal diastolic BP in females and non-obese subjects. The large-scale deployment of wearable medical devices that continuously record BP enables observations that may help elucidate adverse cardiovascular risk profiles in the general population.
