Abstract：
OBJECTIVE: Blood pressure (BP) measurement using an auscultatory sphygmomanometer is recommended for diagnosing hypertension in children. As mercury sphygmomanometers (MSs) are banned owing to environmental concerns, it is crucial to determine the accuracy of mercury-free sphygmomanometers to replace them. We analyzed the accuracy of these devices to guide the National Survey selection.
METHODS: BP was measured thrice each with MS, auscultatory device (AD), and oscillometric device (OD) in 104 participants aged 10-18 using the National Survey data. The difference in BP was defined as the difference between MS and other devices. The BP differences, correlations, and influencing factors were analyzed. The frequencies of hypertension were also compared.
RESULTS: Systolic BP (SBP) and diastolic BP (DBP) differences between MS and AD were 0.88±3.36 mmHg and 0.63±3.95 mmHg, and those between MS and OD were 0.43±5.83 mmHg and 4.57±6.89 mmHg, respectively. The absolute error of <10 mmHg for DBP between MS and OD was 76%. The concordance correlation coefficient between MS and AD was 0.94 for SBP and 0.90 for DBP, and 0.81 and 0.67, respectively for MS and OD. Arm circumference negatively correlated with BP differences except for SBP between the MS and OD. The frequency of hypertension was not different between MS and AD but was underestimated by OD.
CONCLUSIONS: AD correlated well with MS, while OD did not, especially for DBP. The superiority of AD over OD suggests AD as a possible alternative for MS in the National Survey.

摘要：
目的：建议使用听诊式血压计测量血压（BP）以诊断儿童高血压。由于环境问题，水银血压计（MS）被禁止使用，确定无汞血压计的准确性对于更换它们至关重要。我们分析了这些设备的准确性，以指导国家调查的选择。
方法：每次用MS测量三次BP，听诊装置(AD),使用国家调查数据，104名10-18岁的参与者中的示波装置(OD)。BP的差异定义为MS和其他装置之间的差异。BP的差异，相关性，并对影响因素进行了分析。还比较了高血压的发生频率。
结果：MS和AD之间的收缩压BP（SBP）和舒张压BP（DBP）差异为0.88±3.36mmHg和0.63±3.95mmHg，MS和OD之间的值分别为0.43±5.83mmHg和4.57±6.89mmHg，分别。MS和OD之间DBP的绝对误差<10mmHg为76%。MS和AD的一致相关系数SBP为0.94，DBP为0.90。MS和OD分别为0.81和0.67。除MS和OD之间的SBP外，臂围与BP差异呈负相关。高血压的频率在MS和AD之间没有差异，但被OD低估了。
结论：AD与MS有很好的相关性，而OD没有，尤其是DBP。在全国调查中，AD优于OD表明AD是MS的可能替代品。
