Real World Home Blood Pressure Variability in Over 56,000 Individuals With Nearly 17 Million Measurements.

ABSTRACT: BACKGROUND:Using the data from 56,365 individuals, from 185 countries, and a Nokia Health Wireless blood pressure (BP) monitor, we investigated real-world characteristics of BP variability (BPV). METHODS:All included individuals self-measured and uploaded their BP using Bluetooth at least 20 times over a period of ≥1 month at a frequency and duration of their choosing. In total, 16,904,844 BP measurements were analyzed, with a median of 146 measurements per person (interquartile range [IQR] 73-321) over a median of 14 months (IQR 7-31). SD, coefficient of variation, maximum BP, and maximum minus minimum BP difference were all calculated as measures of BPV. RESULTS:BPV showed a distinct pattern, influenced by season of year, day of week, and time of day. BPV index was higher in females comp
