ABSTRACT
Accurate blood pressure (BP) measurement is central to high-quality hypertension management. There is a lack of validated and approved oscillometric BP devices in clinical and epidemiological settings for paediatric age groups.
This study determined the accuracy of the Dinamap Compact TS in measuring the BP of preschool children in Ogbomosho by comparing the measurements obtained with the mercury sphygmomanometer in accordance with the International Protocol of the European Society of Hypertension (ESH-IP2). It also provided oscillometric BP reference values for preschool children.
The study was a cross-sectional survey of 700 children aged between 12 and 60 months from registered day-care centers, nursery and primary schools in Ogbomosho. Each participant underwent 7 same-arm sequential BP measurements by trained researchers alternatively using a mercury sphygmomanometer and the test device. The results were analysed according to the validation criteria of ESH-IP2.
Dinamap Compact TS satisfied the six criteria of Part 1 validation test and the two criteria of Part 2 validation test for SBP and DBP. There was a positive correlation between the 2 devices in terms of SBP (r = 0.947) and DBP (r = 0.910) readings. Using the Bland-Altman plots, nearly all readings (99.3% of SBP and 99.1% of DBP) of the 2 devices were within the limits of agreement, which was indicative of a high level of agreement between the BP devices. Gender-specific BP percentiles, which simultaneously accounted for age, height and height percentile were constructed.
It is recommended that BP of preschool children between the ages of 12 – 60 months could be measured using the Dinamap Compact TS and the developed BP charts should be used as references for easy interpretation and detection of elevated BP.
