健步走与健康教育相结合对同煤职工高血压患者血压的影响

The effect of walking and health education on blood pressure in hypertensive patients of Datong Coal Mine Group

目的探讨8周健步走与健康教育对高血压患者血压的影响。方法选取同煤集团中央机厂高血压患者124人,随机分为4组,即健步走组、健康教育组、健步走＋教育组、对照组。干预前后分别对血压进行测量,观察其干预效果。结果健步走组与健步走＋教育组的退出率相比,其差异有统计学意义（χ^2=5.34,P=0.021）,健步走＋教育组的平均步走次数多于健步走组（t=2.19,P=0.034）。对干预前后血压差值进行析因设计的协方差分析显示,健步走和健康教育对降低血压不存在交互效应（收缩压F=0.18,P=0.675;舒张压F=0.76,P=0.386）。健步走对血压的干预效应差异有统计学意义（收缩压F=9.85,P=0.002;舒张压F=14.17,P〈0.001）;而健康教育干预对血压的效应均无统计学意义（收缩压F=0.61,P=0.436;舒张压F=0.81,P=0.371）。结论本次健步走能够降低血压,而健康教育未能降低血压,但是提高了高血压患者的运动依从性。并且健步走和健康教育对血压的干预效果不存在交互作用。

Objective The aim of this study was to discuss the influences of 8 weeks of walking and health education on blood pressure.Methods 124 patients with hypertension were selected from Datong Coal Mine Group central factory,and then they were randomly divided into four groups,included walking group,health education group,walking plus health education group and control group.Blood pressure was measured and then the intervention effect was observed before and after the intervention.Results There were significant difference between the drop-out rate of walking and walking plus health education group（ χ~2= 5.34,P=0.021）,the step frequency of walking plus health education group was more than the walking groups（ t=2.19,P=0.034）.The factorial design of covariance analysis showed that walking and health education had no interaction effect on lower blood pressure（ systolic blood pressure F=0.18,P=0.675; diastolic blood pressure F=0.76,P=0.386）.Walking intervention effect on blood pressure was statistically significant（ systolic blood pressure F=9.85,P=0.002; diastolic blood pressure F=14.17,P 〈0.001）; And the effect of health education intervention on blood pressure had no statistical significance（ systolic blood pressure F=0.61,P=0.436; diastolic blood pressure F =0.81,P=0.371）.Conclusions The walking could reduce blood pressure,the health education was unable,but it could improve exercise adherence in hypertensive patients.There was no interaction effect between walking and health education on blood pressure.
