Association of home blood pressure with sleep and physical and mental activity, assessed via a wristwatch-type pulsimeter with accelerometer in adults

摘要

This study aimed to examine the associations between home blood pressure (HBP) and sleep and activity assessed using data obtained via a wristwatch-type pulsimeter with accelerometer (Pulsense (R)) using original software. We recruited 28 elderlies and 40 employees aged 24-81 years who were not on hypotensive agents and sleeping drugs. Sleep, activity, and HBP were measured consecutively over a 5-7-day period. Body mass index (BMI), base heart rate (HR0), and age showed significant correlation with HBP in a simple and multiple linear regression analysis. HR0 was positively, and log deep sleep duration, negatively correlated with HBP in the adjusted multiple linear regression analysis. Physical and mental activities were negatively correlated with systolic blood pressure (SBP) in a simple linear regression, but high physical and mental activities tend to reduce deep sleep duration. Self-recorded sleep duration had no relationship with HBP. In conclusion, HR0, BMI, age, deep sleep duration, and activity showed relationships with HBP. Using this type of wristwatch and observing daily sleep and activity data with HBP measurement may have important clinical implication.
