目的：研究体位对高血压患者血压读数的影响。方法和结果：对1487例高血压病患者进行坐位和仰卧位的血压测量。仰卧位的收缩压和舒张压分别比坐位高2·9±-7·8毫米汞和0·9±-5·4毫米汞(P<；0.001)。30~39岁组(3.6±6.8 mm Hg)和80岁以上组(5.3±7.9 mm Hg)卧位与坐位SBP差异最大。在60岁年龄组中，仰卧位和坐位舒张压之间的差异更大。多因素回归分析显示，年龄和性别是仰卧位血压升高的独立预测因素。结论：仰卧位和坐位SBP和DBR存在显著差异，其中年龄和性别是最重要的预测因素。
Objective - The objective of this study was to investigate the impact of postures on blood pressure (BP) readings in patients with hypertension.Methods and results - BP was measured in 1,487 hypertensive patients in sitting and supine positions. The systolic (SBP) and diastolic (DBP) BP in supine position was 2.9 +/- 7.8 mmHg and 0.9 +/- 5.4 mmHg higher, respectively, than in the sitting position (P < 0.001). The greatest difference between supine and sitting SBP was found in those aged between 30 and 39 years (3.6 +/- 6.8 mmHg), and in those who were older than 80 years (5.3 +/- 7.9 mmHg). A greater difference between the supine and sitting DBP was identified in the groups > 60-years of age. Multivariate regression analysis showed that age and sex were independent predictors for the increment of BP in the supine position.Conclusion - There is a significant difference between supine and sitting SBP and DBR with age and sex being the most important predicting factors.
