Accuracy of AOBP in a Chinese Population

BP measurement: The nurse or assistant will leave the room after confirmed validity and the WatchBP will automatically measure BP for the participant at 1-minute intervals for 3 more readings; previous research showed that accurate BP readings could be obtained using 1-minute intervals. This is also the measuring method suggested by the manufacturer. The machine will automatically calculate the mean BP using the 3 readings. The mean BP value will be used for analysis. The diagnostic cutoff for diagnosing HT will be ≥135/85 for AOBP
