Standard guidelines recommend at least ≥20/7 daytime/nighttime measurements for reliable ambulatory BP monitoring, but newer reports suggest ≥8/4 daytime/nighttime measurements are sufficient. Considering BP oscillates across the night, the temporal distribution of measurements across the night may impact nighttime BP and dipping%. To test whether this new recommendation holds for extreme examples of temporal distribution, we compared average nighttime BP and dipping% when using BP measurements only in the first (1st-half) vs. only in the second half (2nd-half) of the night. 000041336 540__ $$fCC BY 000041336 542__ $$fIn copyright - joint owners 000041336 650__ $$aHealth Services$$019903 000041336 650__ $$aSleep$$026066 000041336 650__ $$aBlood Pressure$$015669 000041336 650__ $$aCardiovascular System$$016153 000041336 6531_ $$aheart, lung, & blood 000041336 6531_ $$anocturnal dipping 000041336 6531_ $$anighttime blood pressure 000041336 6531_ $$ablood pressure monitoring 000041336 691__ $$aSchool of Nursing$$041370 000041336 691__ $$aOHSU-PSU School of Public Health$$041366 000041336 692__ $$aOregon Institute of Occupational Health Sciences$$041496 000041336 692__ $$aDepartment of Behavioral Neuroscience$$041394 000041336 692__ $$aOHSU Knight Cardiovascular Institute$$041489 000041336 7001_ $$aBrito, Leandro C.$$uOregon Health and Science University$$041354 000041336 7001_ $$aBowles, Nicole P.$$uOregon Health and Science University$$041354 000041336 7001_ $$aMcHill, Andrew W.$$uOregon Health and Science University$$041354 000041336 7001_ $$aRice, Sean P.M.$$uOregon Health and Science University$$041354 000041336 7001_ $$aButler, Matthew P.$$uOregon Health and Science University$$041354 000041336 7001_ $$aRueda, Jose$$uPortland VA Medical Center$$041358 000041336 7001_ $$aEmens, Jonathan S.$$uPortland VA Medical Center$$041358 000041336 7001_ $$aShea, Steven A.$$uOregon Health and Science University$$041354 000041336 7001_ $$aThosar, Saurabh S.$$uOregon Health and Science University$$041354 000041336 711__ $$aResearch Week$$uOregon Health and Science University$$d2023 000041336 8564_ $$9e9a4de62-c472-4f13-92cf-db1928e98f6d$$s137121$$uhttps://digitalcollections.ohsu.edu/record/41336/files/ResearchWeek.2023.Leandro.Brito.pdf 000041336 980__ $$aResearch Week 000041336 981__ $$aPublished$$b2023-07-24
