Home (HBPM) and ambulatory (ABPM) blood pressure measurements have their advantages and disadvantages in diagnosing and managing hypertension. We studied HBPMs and ABPMs in volunteers taking part in a survey.


Of 366 respondents, 270 provided a total of 5997 triplicate HBPMs (Part 1); 175 also provided data on ABPMs, of which the measurements obtained between 6 am and 10 pm were used in this study (Part 2).


Part 1, When all 5997 triplicate HPPMs were considered, 1st readings tended to be significantly higher than those of the 2nd and 3rd for both, systolic and diastolic pressures, but when the consideration was restricted to the very first triplicate of each of the 270 subjects, this was true only for systolic HBPM. Part 2, The ABPMs tended to have a wider range than the corresponding HBPMs, and to be distributed towards higher values. Of the non-parametric indices of (ABPM - corresponding HBPM), (First Quartile, Median, Third Quartile and Maximim) all but the minima had positive values.


In triplicate HBPMs, the first measurement is usually but not always the highest. Increasing the number of triplicates provided by each subject increases the chance of discriminating between measurements in the triplicates. ABPMs tended to be higher than the corresponding HBPMs.
