ObjectiveTo study the consistency between the electronic sphygmomanometer and mercury sphygmomanometer on blood pressure measuring in children and adolescents.Methods201 children and adolescents were from 6neighborhood of Hunan Province. Dr Mike BPA100 Plus electronic sphygmomanometer was used for three times to test the difference. The blood pressure value of mercury sphygmomanometer was gold standard. The difference of systolic pressure and diastolic pressure of two devices was tested using paired t test, Bland-Altman analysis, and interclass correlation coefficient.ResultsPaired t test showed the statistical difference on the systolic pressure( t = 24. 71, 0. 0001) and diastolic pressure( t = 23. 81, < 0. 0001) of two devices. Both the systolic pressure and diastolic pressure of electronic sphygmomanometer was higher than that of mercury sphygmomanometer. Bland-Altman analysis showed mercury sphygmomanometer couldn 't be simply replaced by electronic sphygmomanometer. The result of interclass correlation coefficient presented a poor consistency between two devices.ConclusionIn order to get scientific conclusion, the comparable study between two blood pressure measuring devices should be conductedbefore a large-scale survey on child and adolescent.
