摘　　要：目的观察短时间内3次偶测血压值的变异程度及其影响因素。方法由经过专门培训的医务人员、在21℃室温下，连续测量2020名成年居民（25～90岁，男994例，女1026例）3次血压，以最大和最小值的差值作为收缩压变异度（△SBP）和舒张压变异度（△DBP）。同时记录年龄、性别、身高、体重、腰围、臀围。计算体重指数（BMI）、向心性肥胖指数（WHR）、脉压（PP），并分析其对血压变异度的影响。结果1．△SBP〉10mmHg者占20％，△DBP〉5mmHg占33．4％。2．女性ASBP高于同年龄段男性，而△DBP两性间无明显差异。3．半数人群首测SBP最高（男48．5％、女53．1％），该亚组△SBP亦最大。结论1．即使严格依照血压测量规程，10min内连续3次的血压测值变异较大。2．女性和增龄是△SBP增大的影响因素。Objective To investigate the variability of blood pressure （BP） in 3 consecutive measurements and its influence factors. Methods After 15 minute resting, BP was read by a senior experienced physician using the same calibrated mercurial sphygmomanometer in 2020 adults （male 994, female 1 026 ） in 3 consecutive with 2 min interval. Body weight, height, hip and waist circumference were recorded. SBP and DBP variability （△SBP and △DBP） was defined as the difference between the maximal and the minimal SBP or DBP respectively. Results 1. In 20% adults △SBP was over 10 mm Hg and in 33.4 % adults △DBP over 5 mm Hg. 2. Before 65 years old, △SBP in female was significantly higher than that in male, but △DBP showed little difference between two sexes. 3. About 50% of the maximal SBP occurred in first reading, and this group had the largest △SBP. Conclusion 1. The difference is quite large in three SBP readings within 10 minutes in 30% adults. 2. Female and aging had impact on the increase of △SBP.
