行为转变理论对高血压前期患者血压昼夜节律变化的影响

Effect of behavioral change theory on circadian rhythm of blood pressure in pre-hypertensive patients

目的探讨行为转变理论（TTM）对高血压前期患者血压昼夜节律变化的影响效果。方法选择120例高血压前期患者为研究对象，按时间顺序分为对照组和干预组各60例，对照组按常规健康指导，干预组按照行为转变理论模式的不同阶段采取相应干预措施。干预后测评患者的动态血压特点、血压昼夜节律变化、晨峰与昼夜节律出现频率。结果干预后干预组非杓型患者仅有11例，10例出现晨峰现象，41例出现血压昼夜节律变化，与对照组比较差异均有统计学意义（均P〈0．01）。结论行为转变理论对高血压前期患者血压昼夜节律变化有明显效果，利于血压的控制。

Objective To evaluate the effect of behavioral change theory on circadian rhythm of blood pressure in pre-hypertensive patients. Methods 120 pre-hypertensive patients were chosen and divided into the control group and the intervention group randomly and evenly. The control group accepted conventional health guidance, while the intervention group accepted different intervention measures depending on the different stages of behavioral change theory model. After the intervention, patients were assessed in terms of dynamic blood pressure characteristics, the circadian rhythm of blood pressure, and the frequency of morning peak and circadian rhythm. Results After the intervention, there were 11 non-dipper cases in the intervention group, morning peak in 10 cases, the change of circadian rhythm of blood pressure in 41 cases, with statistically significant differences compared with the control group （all P〈0.0l）. Conclusion The behavioral change theory has significant effect on circadian rhythm of blood pressure in pre-hypertensive patients, therefore helps to blood pressure control.
