This randomized controlled trial explored the effects of a supine position or a semi-fowler position on postprandial blood pressure (BP) of older adults with primary hypertension and postprandial hypotension (PPH). Ninety-six participants were divided into the supine group, the semi-fowler group, and the control group with block-randomization. After a meal, the patients were placed in a supine position, a 45° semi-fowler position, or allowed daily activities, respectively. BP, heart rate and PPH symptoms were measured 5 times in 120 minutes after the meal. Repeated measurement analysis showed no statistical difference in BP, heart rate and PPH symptom scores among the three groups. BP in all groups decreased rapidly at the 30-minute point, and then moved steadily downward. Taking a supine position or semi-fowler position after meals had no effect on postprandial BP and heart rate after meals in older adults with hypertension and PPH.

这项随机对照试验探讨了仰卧位或半卧位对患有原发性高血压和餐后低血压 (PPH) 的老年人餐后血压 (BP) 的影响。将 96 名参与者分为仰卧组、半捕鸟组和块随机分组的对照组。饭后，将患者分别置于仰卧位、45°半捕鸟位或允许日常活动。餐后 120 分钟内测量 5 次血压、心率和 PPH 症状。重复测量分析显示，三组间血压、心率和PPH症状评分无统计学差异。各组血压在 30 min 时迅速下降，然后稳步下降。
