P084 BLOOD PRESSURES MEASUREMENT WITH SITTING ON THE FLOOR POSITION FOR THE HOME BLOOD PRESSURE MONITORING FOR ASIAN LIFESTYLE

Abstract

Objectives: The current standard method for home blood pressure (BP) measurement involves taking measurements while sitting in a chair. In cultures where floor sitting is common as like in Asian countries, the protocol only using sitting on the chair position can not be applied because of a lack of research for interchangeability. Methods & Materials: Among the participants who visited for evaluation of central blood pressure or pulse wave velocity, a total of 116 participants who agreed to participate in the study were randomly selected. All subjects rested for 5 minutes, and BP measurements were taken at 1-minute intervals according to a randomly assigned order of standard method (chair-sitting) and BP in a seated on the floor (floor-sitting). Results: Of the 116 participants, the median age was 67.5 (with an interquartile range of 59.0 to 75.0), and 82% were male. There were no significant differences in systolic BP (SBP, 127.0 [115.0, 142.2] mmHg in chair-sitting and 129.0 [115.5, 142.2] mmHg in floor-sitting, P = 0.228) and diastolic BP (DBP, 73.5 [66.0, 83.0] mmHg in chair-sitting and 72.0 [66.8, 81.3] mmHg in floor-sitting, P = 0.839) between the two positions. Conclusions: These findings provide important insights into securing the reliability of home BP measurements through the commonly practiced floor-sitting posture in cultures where floor sitting is common. Furthermore, this could serve as substantial evidence for providing specific home BP measurement guidelines to patients who adhere to a floor-sitting lifestyle.
