目的：我们描述了全国健康与营养检查调查（NHANES）血压（BP）观察员的培训和协议标准化和评估BP measurement.Methods的质量：参与者是8岁及以上的人谁有他们的BP测量（n = 7467）在NHANES 1999-2000年。袖带宽度/臂围比（CW/AC），结束数字的偏好，和观察员的协议进行了examined.Results：在逐步主成分多元回归分析，CW/AC占不到2%的变异R-2在所有读数。所有末端数字的频率接近20%（“0”末端数字= 21%收缩压和23%舒张压）。平均收缩压读数不存在总体观察者效应。显著的观察者效应（P
Objective: We describe the National Health and Nutrition Examination Survey (NHANES) blood pressure (BP) observer training and protocol standardization and evaluate the quality of BP measurement.Methods: The participants were persons aged 8 years and older who had their BP measured (n = 7467) during NHANES 1999-2000. Cuff width/arm circumference ratio (CW/AC), end digit preference, and observer agreement were examined.Results: In stepwise principal components multiple regression analysis, CW/AC accounted for less than 2% of variability R-2 in all readings. The frequencies for all end digits were close to 20% ("0" end digit = 21% systolic and 23% diastolic). No overall observer effect was present for mean systolic BP readings. A significant observer effect (P
