同体自身饭前饭后血压差异性研究

Research on the differences of consubstantial blood pressure before and after meals

目的:通过饭前饭后血压值的测量,探讨同体自身饭前和饭后血压值有无差异性,探究人体饭后困倦是否受自身血压的影响。方法:对160例观察对象采用同体自身对照,使用电子血压计分别测量饭前血压和饭后半小时血压,对测量的数据采用配对t检验,进行统计学分析。结果:160例同体自身血压测量,饭后收缩压和舒张压均较饭前明显下降,差异有统计学意义(P<0.001)。结论 :通过160例观察对象同体自身饭前饭后血压值的观察结果表明,饭后困倦与饭后人体大部分血液流经胃肠道帮助消化吸收,从而使循环血流量减少,导致血压下降有关。

Objective： To evaluate the difference of blood pressure before and after meals, and to explore whether the sleepiness after meals is under the influence of blood pressure after meals. Methods： Use electronic blood pressure monitor, BP of 160 people was measured before and half an hour after meals, and the results were analyzed using paired samples test. Results： Compared to BP before meals, BP after meals was significantly dropped （P 〈 0.001）. Conclusion ： We conclude that sleepiness after meals may result from the lower BP.
