Abstract：
Accurate blood pressure (BP) measurement is crucial for hypertension detection and management. The Korea National Health and Nutrition Examination Survey (KNHANES) assesses the health of Koreans using representative cross-sectional data. BP measurements were historically done with mercury sphygmomanometers for participants aged ≥10 years. However, KNHANES transitioned to Greenlight 300TM (mercury-free auscultatory device) in 2020 for participants aged ≥6 years and used dual devices (Microlife WatchBP Office AFIB and Greenlight) in 2021-2022. To ensure consistency, KNHANES will adopt Microlife as the unified BP device with Greenlight for device validation from 2023. Under the new protocol, participants aged ≥6 years will have their BP measured three times at 30-second intervals after a 5-minute rest under ambient temperature (20-25℃) and noise ≤65 dB. The average of the 2nd and 3rd readings will be used as the representative BP value. The quality control (QC) program involves four trained examiners passing the \"quality control and assurance of BP measurement program\" three times annually, and undergoing \"video monitoring of weekly calibration process\" once a year. Additionally, the QC team will conduct \"on-site evaluations of BP measurement\" at mobile examination centers three times a year. A Five-Step QC process for BP devices was also developed. This document outlines the standardized BP measurement protocol and rigorous QC program in KNHANES, aiming to ensure accurate and reliable BP data for epidemiological research and public health policymaking in South Korea.
摘要：
准确的血压（BP）测量对于高血压的检测和管理至关重要。韩国国家健康和营养检查调查（KNHANES）使用代表性的横截面数据评估韩国人的健康状况。历史上，年龄≥10岁的参与者使用水银血压计进行BP测量。然而,KNHANES于2020年过渡到Greenlight300TM（无汞听诊设备），适用于年龄≥6岁的参与者，并在2021-2022年使用了双设备（MicrolifeWatchBPOfficeAFIB和Greenlight）。为了确保一致性，从2023年开始，KNHANES将采用Microlife作为统一的BP设备，与Greenlight一起进行设备验证。根据新协议,年龄≥6岁的参与者将在环境温度(20-25℃)和噪声≤65dB下休息5分钟后,每隔30秒测量3次血压.第二和第三读数的平均值将用作代表性BP值。质量控制（QC）计划涉及四名训练有素的审查员，每年通过“BP测量计划的质量控制和保证”三次，每年进行一次“每周校准过程视频监控”。此外,QC小组将每年在移动考试中心进行三次“BP测量现场评估”。还开发了用于BP设备的五步QC过程。本文档概述了KNHANES中的标准化BP测量协议和严格的QC计划，旨在确保准确可靠的BP数据，用于韩国的流行病学研究和公共卫生政策制定。
