急慢性心理应激对驻疆军人心血管反应的影响

Effect of acute and chronic psychological stress to cardiovascular responses in soldiers stationed in Xinjiang

目的探讨驻疆军人急性应激状态下心血管反应的特点及其与慢性心理应激水平之间的关系。方法采用整群抽样的方法,对650名驻疆官兵进行问卷调查和试验研究,问卷选用的是军人心理应激自评问卷,以收缩压、舒张压和心率为心血管反应参数。结果驻疆军人心理应激水平在是否独生子女、职别、兵源地上的差异有统计学意义(P<0.01);驻疆军人心算任务前后血压和心率值的差异有统计学意义(P<0.01);心理应激高分组的驻疆军人在心算任务前后血压值均高于低分组,差异有统计学意义(P<0.01);不同心理应激水平的驻疆军人应激前后心血管应激反应指标波动值的差异无统计学意义(P>0.05)。结论驻疆军人心理应激状况总体良好;慢性心理应激是诱发驻疆军人高血压病的危险因素之一。

Objective To explore the characteristics of the cardiovascular responses among soldiers stationed in Xinjiang under acute stress,and the relationship between the cardiovascular responses and the levels of chronic stress.Methods A total of 650 soldiers were chosen by random cluster sampling and measured with the Psychological Stress Self-evaluation Test.Meanwhile,systolic blood pressure,diastolic blood pressure,and heart rate were recorded as cardiovascular responses parameters.Results There were statistically significant differences respectively in whether they were only-child,job title and place of domicile（P〈0.01）.There were statistically significant differences in the changes of cardiovascular responses among soldiers stationed in Xinjiang under acute stress（P 〈0.01）.Compared with low stress level score group,high score group had higher blood pressure in the experiment.The differences were statistically significant（P〈0.01）.High score group was compared with the low score group,the differences of the cardiovascular fluctuation indicators were not statistically significant（（P〉0.05）.Conclusions The soldiers’ psychological stress levels were generally good.Chronic psychological stress is one of the risk factors of hypertension in soldiers stationed in Xinjiang.
